DETAILED DESCRIPTION
[0008] It will be appreciated that for simplicity and clarity of
illustration, where appropriate, reference numerals have been
repeated among the different figures to indicate corresponding or
analogous elements. Additionally, numerous specific details are set
forth in order to provide a thorough understanding of the
embodiments described herein. However, it will be understood by
those of ordinary skill in the art that the embodiments described
herein can be practiced without these specific details. In other
instances, methods, procedures and components have not been
described in detail so as not to obscure the related relevant
feature being described. The drawings are not necessarily to scale
and the proportions of certain parts may be exaggerated to better
illustrate details and features. The description is not to be
considered as limiting the scope of the embodiments described
herein.
[0009] Several definitions that apply throughout this disclosure
will now be presented.
[0010] The term "coupled" is defined as connected, whether directly
or indirectly through intervening components, and is not
necessarily limited to physical connections. The connection can be
such that the objects are permanently connected or releasably
connected. The term "substantially" is defined to be essentially
conforming to the particular dimension, shape, or other word that
"substantially" modifies, such that the component need not be
exact. For example, "substantially cylindrical" means that the
object resembles a cylinder, but can have one or more deviations
from a true cylinder. The term "comprising" means "including, but
not necessarily limited to"; it specifically indicates open-ended
inclusion or membership in a so-described combination, group,
series and the like.
[0011] FIG. 1 shows an embodiment of refrigeration equipment 100
including a compressor 11, a condenser 12, a dry filter 13, a
capillary 14, a noise reduction device 15, and an evaporator 16.
Air having a low temperature and low pressure flows into the
compressor 11. The compressor 11 compresses the air, and the
compressed air has a high temperature and high pressure. The
compressed air flows from the compressor 11 to the condenser 12 to
be cooled. The air cooled by the condenser 12 has a low temperature
and a high pressure. The cooled air having a low temperature and a
high pressure flows through the dry filter 13 into the capillary
14. The air flowed into the capillary is condensed into a
refrigerant liquid having a low temperature and low pressure. The
refrigerant liquid is passed from the capillary 14 to the
evaporator 16 through the noise reduction device 15. The
refrigerant liquid flowing into the evaporator 16 is evaporated
into air having a low temperature and low pressure. The air having
a low temperature and low pressure is once again passed through the
compressor 11, and the cycle continues as described above.
[0012] The noise reduction device 15 includes at least one
transition tube through which the refrigerant liquid flows from the
capillary 14 to the evaporator 16. A diameter of the at least one
transition tube gradually increases from the capillary 14 to the
evaporator 16. The gradually increasing diameter of the transition
tube reduces a speed of flow of the refrigerant liquid from the
capillary 14 to the evaporator 16, thereby preventing a sputtering
noise caused by a speed of flow of the refrigerant liquid being too
fast from the capillary 14 to the evaporator 16. Referring to FIG.
2, the noise reduction device 15 further includes a damping
adhesive 154 for further reducing noise of the refrigerant liquid
during a transition from the capillary 14 to the evaporator 16. It
should be understood that the refrigeration equipment 100 further
includes a fan, a humidity control system, a housing, and other
components which will not be discussed herein.
[0013] FIGS. 2-3 show a first embodiment of a structure of the
noise reduction device 15. In one embodiment, the noise reduction
device 15 includes a first transition tube 151, a second transition
tube 152, and a coupling portion 153. A first end of the first
transition tube 151 is coupled to the capillary 14, a second end of
the first transition tube 151 opposite to the first end is coupled
to a first end of the second transition tube 152 through the
coupling portion 153. A second end of the second transition tube
152 opposite to the first end is coupled to the evaporator 16. In
one embodiment, an inner diameter .PHI.A of the first transition
tube 151 is greater than an inner diameter of the capillary 14, and
an inner diameter .PHI.B of the second transition tube 152 is
greater than the inner diameter .PHI.A of the first transition tube
151. In one embodiment the inner diameter of the capillary 14 is
1.8 mm, the inner diameter of the first transition tube 151 is 3.2
mm, and the inner diameter of the second transition tube 152 is 4.0
mm. An inner diameter of the coupling portion 153 gradually
increases from the first transition tube 151 to the second
transition tube 152. An end of the coupling portion 153 directly
coupled to the first transition tube 151 is substantially equal to
the inner diameter .PHI.A of the first transition tube 151, and an
end of the coupling portion 153 directly coupled to the second
transition tube 152 is substantially equal to the inner diameter
.PHI.B of the second transition tube 152.
[0014] In the first embodiment, a length of the first transition
tube 151 is equal to a length of the second transition tube 152.
For example, the length of the first transition tube 151 is 140 mm,
and the length of the second transition tube 152 is 140 mm.
[0015] In the first embodiment, the damping adhesive 154 covers
over a connecting joint between the first transition tube 151 and
the capillary 14 and a connecting joint between the second
transition tube 152 and the evaporator 16. In other embodiments,
the damping adhesive 154 covers from the connecting joint between
the first transition tube 151 and the capillary 14 to the
connecting joint between the second transition tube 152 and the
evaporator 16.
[0016] In the first embodiment, the first transition tube 151 is
coupled to the capillary 14 by welding, and the second transition
tube 152 is coupled to the evaporator 16 by welding. In other
embodiments, the first transition tube 151 may be coupled to the
capillary 14 by other means, such as by screwing, and the second
transition tube 152 may be coupled to the evaporator 16 by other
means, such as by screwing.
[0017] In the first embodiment, the first transition tube 151, the
coupling portion 153, and the second transition tube 152 are
integrally formed. In other embodiments, the first transition tube
151, the coupling portion 153, and the second transition tube 152
are coupled together by welding or by other means.
[0018] In the first embodiment, the first transition tube 151, the
second transition tube 152, and the coupling portion 153 are made
of copper. In other embodiments, the first transition tube 151, the
second transition tube 152, and the coupling portion 153 may be
made of stainless steel or other material.
[0019] In the first embodiment, inner walls of the first transition
tube 151, the second transition tube 152, and the coupling portion
153 are smooth.
[0020] In the first embodiment, an end portion 1521 of the second
transition tube 152 coupled to the evaporator 16 is a rounded
connecting joint. In another embodiment, an end portion of the
first transition tube 151 coupled to the capillary 14 may also be a
rounded connecting joint.
[0021] In other embodiments, the noise reduction device 15 may
include more than two transition tubes, such as shown in FIG.
4.
[0022] FIG. 4 shows a second embodiment of the structure of the
noise reduction device 15. In the second embodiment, the noise
reduction device 15 includes transition tubes 151a, 151b, and 151c.
The transition tube 151a is coupled to the capillary 14, and the
transition tube 151c is coupled to the evaporator 16. The damping
adhesive 154 covers over a junction between the transition tube
151a and the capillary 14 and a junction between the transition
tube 151c and the evaporator 16. It should be understood that the
damping adhesive 154 may further cover all points of the transition
tubes 151a, 151b, and 151c.
[0023] The embodiments shown and described above are only examples.
Even though numerous characteristics and advantages of the present
technology have been set forth in the foregoing description,
together with details of the structure and function of the present
disclosure, the disclosure is illustrative only, and changes may be
made in the detail, including in matters of shape, size and
arrangement of the parts within the principles of the present
disclosure up to, and including, the full extent established by the
broad general meaning of the terms used in the claims.
