Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The embodiment relates to a distributor, and more
particularly, to a distributor which allows inputted liquid and
gaseous refrigerants to evenly flow and be discharged and a
refrigerant circulation system comprising the same.
[0003] 2. Description of the Related Art
[0004] In general, an air conditioner is a home appliance that
cools or heats a predetermined space by using a refrigeration
system using characteristics depending on changes in pressure and
temperature of refrigerants.
[0005] FIG. 1 is a configuration diagram schematically showing a
general refrigeration system.
[0006] Referring to FIG. 1, the refrigeration system includes a
compressor 10 that compresses the refrigerant in a high-temperature
and high-pressure gaseous state, a condenser 20 that condenses
refrigerant compressed by the compressor 10 into a liquid state by
heat radiation using air blowing of a cooling fan 22, a capillary
tube 40 that expands the liquid refrigerant condensed by the
condenser 20 into low-pressure liquid refrigerant by a throttle
operation, a distributor 30 that evenly distributes the liquid
refrigerant condensed by the condenser 20 to the capillary tube 40,
and an evaporator 50 that evaporates the low-temperature and
low-pressure refrigerant expanded by the capillary tube 40 into
low-temperature and low-pressure gaseous refrigerant at the same
time when providing cool air by using evaporation latent heat while
evaporating the low-temperature and low-pressure refrigerant
expanded by the capillary tube 40 by air blowing of the cooling fan
52. Accordingly, the refrigeration system of the air conditioner
cools a room by a series of cooling cycles constituted by the
pressure 10, the condenser 20, the distributor 30, the capillary
tube 40, and the evaporator 50.
[0007] Meanwhile, the distributor 30 includes an inlet flow passage
that is in communication with the capillary tube 40 and the
evaporator 50, more specifically, a plurality of distribution flow
passages that are in communication with a plurality of tubes
constituting the evaporator 50. In addition, the inlet flow passage
and the distribution flow passages are in communication with each
other, such that the liquid refrigerant that flows in the inlet
flow passage through the inlet flow passage is distributed into
tubes of the evaporator 50 through the distribution flow
passages.
[0008] However, by the distributor in the related art, the
following problem occurs.
[0009] As described above, the refrigerant that flows in the inlet
flow passage in part includes the liquid refrigerant and the
gaseous refrigerant. However, since the liquid refrigerant and the
gaseous refrigerant have specific gravities different from each
other, the liquid refrigerant and the gaseous refrigerant that flow
in the inlet flow passage through the capillary tube 40 are not
evenly mixed with each other and the liquid refrigerant flows in
some of the tubes of the evaporator 50 and the gaseous refrigerant
flows in other tubes of the evaporator 50 through the distribution
flow passage, such that the efficiency of a heat exchange cycle is
deteriorated.
SUMMARY OF THE INVENTION
[0010] The embodiment relates to a distributor. In the present
invention, refrigerant that flows in from an inlet pipe flows
through an inlet flow passage of the distributor to be thus
transferred to the distribution flow passage of the distributor,
such that the refrigerant flows on the distribution flow passage to
be evenly distributed and transferred to a plurality of outlet
pipes. Accordingly, according to the present invention, the
refrigerant that flows in through an inlet pipe by the distributor
is evenly distributed to the plurality of outlet pipes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Reference will now be made in detail to the embodiments of
the present disclosure, examples of which are illustrated in the

[0017] In the following detailed description of the preferred
embodiments, reference is made to the accompanying drawings that

specific preferred embodiments in which the invention may be
practiced. These embodiments are described in sufficient detail to
enable those skilled in the art to practice the invention, and it
is understood that other embodiments may be utilized and that
logical structural, mechanical, electrical, and chemical changes
may be made without departing from the spirit or scope of the
invention. To avoid detail not necessary to enable those skilled in
the art to practice the invention, the description may omit certain
information known to those skilled in the art. The following
detailed description is, therefore, not to be taken in a limiting
sense, and the scope of the present invention is defined only by
the appended claims.
[0018] Hereinafter, a distributor and a refrigeration circulation
system comprising the same according to an embodiment of the
present invention will be described in detail with reference to the
accompanying drawings.
[0019] FIG. 2 is a perspective of a distributor according to an
embodiment of the present invention. FIG. 3 is an exploded
cross-sectional view according to an embodiment of the present
invention. FIG. 4 is a cross-sectional view according to an
embodiment of the present invention.
[0020] Referring to FIG. 2, the distributor 100 according to the
present invention includes a distributor body 110 and a distributor
head 120. The distributor body 110 is inserted and fixed into the
distributor head 120. For example, the distributor body 110 can be
fixed with being inserted into the distributor head 120 by bonding
or soldering.
[0021] More specifically, the distributor body 110 is formed in a
hollow cylindrical shape having generally the same diameter.
Accordingly, an inner diameter and an outer diameter of the
distributor body 110 generally have the same value. In addition, an
inlet flow passage 111 and a mixed flow passage 113 are provided in
the distributor body 110.
[0022] The inlet flow passage 111 is provided at a central portion
and a lower portion of the distributor body 110 in the figure. An
inlet pipe 10 (see FIG. 4) for transferring refrigerant expanded at
low pressure in a capillary tube (not shown) is connected to a
lower end in the figure, that is, to a upstream portion of the
inlet flow passage 111. Of course, the capillary tube may be
directly connected. In addition, an upper end in the figure, that
is, a downstream portion of the inlet flow passage 111 is in
communication with a lower end in the figure of the mixed flow
passage 113. Liquid refrigerant and some gaseous refrigerant
expanded by the capillary tube flow in the inlet flow passage
111.
[0023] The mixed flow passage 113 is provided at a central portion
and a lower portion of the distributor body 110 in the figure. The
mixed flow passage 113 has a flow cross-sectional area
comparatively smaller than the inlet flow passage 111. In addition,
a downstream portion of the mixed flow passage 113 is in
communication with an upstream portion of a distribution flow
passage 121 to be described below. The liquid and gaseous
refrigerants that flow on the inlet flow passage 111 flow in the
mixed flow passage 113. However, the mixed flow passage 113 has a
flow cross-sectional area smaller than the inlet flow passage 111.
Accordingly, the liquid and gaseous refrigerants that flow on the
inlet flow passage 111 are mixed with each other. More
specifically, the liquid refrigerant has a specific gravity
comparatively larger than the gaseous refrigerant. Therefore, for
example, like a case in which the refrigerant is transferred to the
inlet flow passage 111 through the inlet pipe 10 having a J or U
shape, when the liquid and gaseous refrigerants that flow in the
inlet flow passage 111 flow on not a linear trajectory but a curved
trajectory, the liquid refrigerant flows in one portion of the
inlet flow passage 111 adjacent to an inner peripheral surface of
the distributor body 110 and the gaseous refrigerant flows at the
rest portion of the inlet flow passage 111. In addition, the liquid
and gaseous refrigerants that flow on the inlet flow passage 111,
which are partitioned from each other, flow in different directions
to be mixed with each other while flowing on the mixed flow passage
113 having a flow cross-sectional area comparatively smaller than
the inlet flow passage 111.
[0024] Meanwhile, the flow cross-sectional area of the mixed flow
passage 113 is substantially reduced by a flow interference unit
115 provided on the top of the inner peripheral surface of the
distributor body 110. The flow interference unit 115 extends
radially on the top of the inner peripheral surface of the
distributor body 110. Therefore, a part of the downstream portion
of the inlet flow passage 111 has a diameter comparatively smaller
than the rest portions of the inlet flow passage 111 by the flow
interference unit 115, such that the mixed flow passage 113 may be
formed. In addition, one surface of the flow interference unit 115
facing the downstream portion of the inlet flow passage 111, that
is, the bottom of the flow interference unit 115 in the figure is
rounded. This purpose is to prevent a vortex phenomenon from being
generated by an edge between the inner peripheral surface of the
distributor body 110 corresponding to the downstream portion of the
inlet flow passage 111 and one surface of the flow interference
unit 115 while the liquid and gaseous refrigerants are transferred
to the mixed flow passage 113.
[0025] Further, a projection portion 117 is provided in the
distributor body 110. The projection portion 117 of the distributor
body 110 is provided on the inlet flow passage 111. An end portion
of the inlet pipe 10 connected to the inlet flow passage 111 is
suspended on the projection portion 117 of the distributor body
110. The projection portion 117 of the distributor body 110 is
substantially formed by stepping the upstream portion and the
downstream portion of the inlet flow passage 111.
[0026] Meanwhile, a lower portion in the figure of the distributor
head 120, that is, the upstream portion is formed in a hollow
cylindrical shape having an inner diameter corresponding to an
outer diameter of the distributor body 110. In addition, an upper
portion in the figure of the distributor head 120, that is, the
downstream portion has a cone shape of which a diameter gradually
increases in comparison with the lower portion in the figure the
distributor head 120. Of course, the upstream portion and the
downstream portion of the distributor head 120 are preferably
formed integrally with each other.
[0027] In addition, the distribution flow passage 121 is provided
in the distributor head 120. The distribution flow passage 121 is
configured to distribute the liquid and gaseous refrigerants that
are mixed with each other while flowing on the mixed flow passage
113 to a plurality of tubes (not shown) constituting an evaporator
(not shown). For this purpose, the distribution flow passage 121
includes a mixing unit 122 and a plurality of distribution units
123.
[0028] A lower portion in the figure of the mixing unit 122, that
is, the upstream portion is in communication with the mixed flow
passage 113. In addition, an upper portion in the figure of the
mixing unit 122, that is, the downstream portion is in
communication with lower portions in the figure of the plurality of
distribution units 123, that upstream end portions. The upstream
portion of the mixing unit 122 has a flow cross-sectional area
comparatively larger than the mixed flow passage 113. It can be
expected a phenomenon that the liquid and gaseous refrigerants that
are mixed in the mixed flow passage 113 and transferred to the
mixing unit 122 are once again mixed. In the embodiment, the
upstream portion of the mixing unit 122 has the same flow
cross-sectional area as the inlet flow passage 111, but is not
necessarily limited thereto and may have a flow cross-sectional
area comparatively larger than the mixed flow passage 113. Further,
the downstream portion of the mixing unit 122 has a flow
cross-sectional area that is reduced toward the distribution unit
123. This purpose is to evenly distribute and transfer the
refrigerant that flows on the mixing unit 122 to the distribution
unit 123. For this, the downstream portion of the mixing unit 122
has a cone shape using a virtual plane generally perpendicularly
passing through a virtual straight line parallel to a flow
direction of the refrigerant. More specifically, in the downstream
portion of the mixing unit 122, the top of the cone projected on
the downstream portion of the mixing unit 122 is cut, such that a
cross section in a direction where the refrigerant flows has a
trapezoidal shape.
[0029] As described above, in the distribution unit 123, each lower
portion in the figure, that is, the upstream portion is in
communication with the downstream portion of the mixing unit 122.
More specifically, the upstream portions of the distribution unit
123 are positioned separated from each other by a predetermined
central angle on a virtual circular shape having the same circular
center at the downstream portion of the mixing unit 122
corresponding to a cone-shape outer peripheral surface. In
addition, an upstream end portion to a downstream end portion of
the distribution unit 123 extends to slope in the direction where
the refrigerant flows at a predetermined angle. In addition, the
outlet pipe 20 (see FIG. 4) for transferring the refrigerant to the
tube is connected to the downstream portion of the distribution
unit 123.
[0030] Meanwhile, a distribution projection 125 is provided in the
distributor head 120 corresponding to an inner part of the
distribution flow passage 121. A part of the downstream portion of
the mixing unit 122 excluding a portion which is in communication
with the upstream end portion of the distribution unit 123 is
projected in a direction opposite to the flowing direction of the
refrigerant to form the distribution projection 125. In the
embodiment, the distribution projection 125 has the cone shape as a
whole, but the shape of the distribution projection 125 is not
limited thereto. The distribution projection 125 is configured to
evenly distribute the refrigerant that flows on the mixing unit 122
to the distribution unit 123. That is, the refrigerant that flows
on the distribution unit 123 flows substantially toward the
distribution unit 123 by the distribution projection 125. Further,
the distribution projection 125 serves to reduce the flow
cross-sectional area of the downstream portion of the mixing unit
122 which is in communication with the distribution unit 123 toward
the distribution unit 123.
[0031] Further, a projection portion 127 is provided in the
distributor head 120. The projection portion 127 of the distributor
head 120 is provided on the distribution unit 123 adjacent to the
downstream end portion of the distribution unit 123. The projection
portion 127 of the distributor head 120 is a location on which an
end portion of the outlet pipe 20 connected to the downstream end
portion of the distribution unit 123 is suspended. The projection
portion 127 of the distributor head 120 is formed by stepping the
distribution unit 123.
[0032] Next, an operation of an embodiment of a distributor and a
refrigeration circulation system comprising the same according to
the present invention will be described in more detail with
reference to the accompanying drawings.
[0033] FIG. 5 is a cross-sectional view showing a process in which
refrigerant is distributed by an embodiment of a distributor
according to the present invention.
[0034] Referring to FIG. 5, refrigerant expanded in a capillary
tube is first transferred to an inlet flow passage 111 through an
inlet pipe 10. At this time, most of refrigerants transferred to
the inlet flow passage 111 are a liquid refrigerant (indicated by
solid lines in the figure), but some of refrigerants are
transferred to the inlet flow passage 111 as a gaseous refrigerant
(indicated by dot lines in the figure). Further, the liquid
refrigerant will flow on a part of the inlet flow passage 111
mainly adjacent to an inner surface of the distributor body 110 and
the gaseous refrigerant will flow on the rest part of the inlet
flow passage 111 by a difference in centrifugal force depending on
a difference in specific gravity between the liquid refrigerant and
the gaseous refrigerant.
[0035] Meanwhile, the liquid and gaseous refrigerants that flow on
the inlet flow passage 111 are transferred to the mixed flow
passage 113. In addition, the liquid and gaseous refrigerants
transferred to the mixed flow passage 113 are mixed with each other
to be transferred to the distribution flow passage 121 while
flowing on the mixed flow passage 113. However, the mixed flow
passage 113 has a flow cross-sectional area comparatively smaller
than the distribution flow passage 121 as described above.
Accordingly, the liquid and gaseous refrigerants are mixed with
each other to be transferred to the distribution flow passage 121
while flowing on the mixed flow passage 113.
[0036] In addition, the liquid and gaseous refrigerants transferred
to the distribution flow passage 121 are remixed in the mixing unit
122 of the distribution flow passage 121 having the flow
cross-sectional area comparatively larger than the mixed flow
passage 113. As such, the liquid and gaseous refrigerants that are
remixed in the mixing unit 122 are transferred to the outlet pipe
connected to the distribution unit 123 through the distribution
unit 123 of the distribution flow passage 121.
[0037] At this time, the flow cross-sectional area of the
downstream portion of the mixing unit 122 is reduced toward the
distribution unit 123 by the distribution projection 125. Further,
the refrigerant that flows on the mixing unit 122 is substantially
guided to the distribution unit 123 by the distribution projection
125. Accordingly, the refrigerant that flows on the mixing unit 122
can be evenly distributed to the outlet pipe 20 through the
distribution unit 123.
[0038] Next, the refrigerant that flows on the outlet pipe 20 is
transferred to tubes of an evaporator (not shown) connected to the
outlet pipe 20. In addition, the refrigerant transferred to the
evaporator by circulating a compressor (not shown), a condenser
(not shown), a capillary tube (not shown), a distributor (not
shown), and an evaporator in sequence to drive a refrigeration
cycle.
[0039] It will be appreciated by those skilled in the art that
substitutions, modifications, and changes may be made in these
embodiments without departing from the principles and the spirit of
the general inventive concept, the scope of which is defined in the
appended claims and their equivalents.
[0040] In the above-mentioned embodiment, a component forming the
mixed flow passage is referred to as a flow interference unit, but
its name is not limited to the flow interference unit. That is,
when an inlet direction of the refrigerant that flows in the inlet
flow passage can be substantially changed, although the component
is referred to as another name, for example, a direction converting
unit, the component will be substantially the same component.
[0041] Further, in the above-mentioned embodiment, one surface of
the flow interference unit facing the inlet flow passage is
rounded, but is not limited thereto. That is, one surface of the
flow interference unit facing the inlet flow passage may be
perpendicular to the flowing direction of the refrigerant that
flows on the inlet flow passage.
[0042] In a distributor and a refrigeration circulation system
comprising the same according to the present invention, which are
configured as described above, a refrigerant that flows in through
an inlet pipe is evenly distributed and discharged to a plurality
of outlet pipes. Accordingly, according to the present invention,
the refrigerant that is evenly distributed to the outlet pipe is
transferred to a plurality of tubes constituting, for example, an
evaporator, such that it can be expected an effect in which the
efficiency of a refrigeration cycle is substantially increased.
