Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of Korean Patent
Application No. 2004-46195, filed on Jun. 21, 2004 in the Korean
Intellectual Property Office, the disclosure of which is
incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] An apparatus consistent with the present invention relates
to a compressor and, more particularly, to a compressor designed to
discharge a refrigerant compressed in the compressor to the outside
through a cylinder head and a discharge muffler.
[0004] 2. Description of the Related Art
[0005] Generally, a compressor is a component for a freezing cycle,
which generates conditioned air by circulating a refrigerant in an
air conditioner or a freezer, and has a function to compress the
refrigerant with high temperature and pressure, and to discharge a
compressed refrigerant.
[0006] One type of such a compressor is a linear compressor, which
will be described as one example of a conventional compressor
hereinafter. The linear compressor 1 forces a piston to linearly
reciprocate by means of a linear motor, which is driven by virtue
of cooperation of magnetic members generating a magnetic flux
subjected to a directional variation. Referring to FIG. 1, the
linear compressor 1 is provided with various components, which can
be broadly classified into a compressing part to intake the
refrigerant from a closed container 14 and to discharge the
refrigerant after compressing the refrigerant, and a driving part
to provide a compressing force to the compressing part.
[0007] The compressing part is provided with a cylindrical cylinder
block 9 having a compressing chamber 9a defined therein, and with a
rod-shaped piston 11 equipped in the compressing chamber 9a of the
cylinder block 9 to linearly reciprocate up and down within the
compressing chamber 9a. Under the cylinder block 9, the compressing
part is further provided with a cylinder head 10 having an intake
chamber 10b to intake the refrigerant into the compressing chamber
9a and a discharge chamber 10a to discharge the compressed
refrigerant to the outside. Additionally, a discharge muffler 12 is
equipped at one side of the cylinder head 10 under the cylinder
block 9, for reducing noise due to refrigerant discharge from the
discharge chamber 10a.
[0008] The driving part is provided with a stator 13 and a mover 3,
between which an electromagnetic force is generated to reciprocate
the piston 11 within the cylinder block 9. As the piston 11 is
reciprocated within the cylinder block 9, the refrigerant is
compressed to a high temperature and pressure, and the compressed
refrigerant is then discharged to the outside, through a tube 12a
provided to the discharge muffler 12, after passing through the
discharge chamber 10a and the discharge muffler 12.
[0009] However, the conventional compressor has a problem in that,
when passing through the discharge chamber 10a and the discharge
muffler 12, heat is transferred from the refrigerant of the high
temperature and pressure to the compressing chamber 9a through the
cylinder head 10 and the cylinder block 9, thereby lowering
efficiency of the compressor 1.
SUMMARY OF THE INVENTION
[0010] Illustrative, non-limiting embodiments of the present
invention overcome the above disadvantages and other disadvantages
not described above. Also, the present invention is not required to
overcome the disadvantages described above, and an illustrative,
non-limiting embodiment of the present invention may not overcome
any of the problems described above.
[0011] The present invention has been made in view of the above and
other problems, and an aspect of the present invention is to
provide a compressor designed to prevent heat of a refrigerant
passing through a discharge chamber and a discharge muffler in a
cylinder head from being transferred to a compressing chamber,
thereby enhancing efficiency of the compressor.
[0012] Additional aspects and/or advantages of the invention will
be set forth in part in the description which follows and, in part,
will be apparent from the description, or may be learned by
practice of the invention.
[0013] Consistent with the present invention, these and/or other
aspects are accomplished by providing a compressor comprising a
discharge chamber to contain temporarily a refrigerant compressed
in a compressing chamber, and a heat-radiating member to radiate
heat from the discharge chamber to the outside.
[0014] The heat-radiating member may have one end submerged to oil
flowing in the compressor.
[0015] The heat-radiating member may be a heat-radiating fin made
of a metallic material.
[0016] The compressing chamber may be defined in a space between a
cylinder block and a piston received in the cylinder block, and the
discharge chamber may be defined in a cylinder head disposed on the
cylinder block.
[0017] The heat-radiating member may be provided to the cylinder
head.
[0018] The cylinder head may be provided with a discharge muffler
to prevent noise from the compressing chamber from being

DETAILED DESCRIPTION OF THE ILLUSTRATIVE, NON-LIMITING EMBODIMENTS
OF THE INVENTION
[0027] Reference will now be made in detail to illustrative,
non-limiting embodiments of the present invention, examples of
which are illustrated in the accompanying drawings. The embodiments
are described below to explain the present invention by referring
to the drawings. In the exemplary embodiment, a linear compressor
will be explained as one example of a compressor.
[0028] Referring to FIG. 2, a linear compressor 20 according to the
present invention comprises a closed container 24, a compressing
part to intake a refrigerant from the closed container 24 and to
discharge the refrigerant after compressing the refrigerant, and a
driving part to provide a compressing force to the compressing
part.
[0029] The compressing part is provided with a cylindrical cylinder
block 29 having a compressing chamber 29a defined therein, and with
a rod-shaped piston 31 equipped in the compressing chamber 29a of
the cylinder block 29 to linearly reciprocate up and down within
the compressing chamber 9a. The cylinder block 29 is supported by a
support spring 25.
[0030] A cylinder head 30 with an intake chamber 30b defined
therein to intake the refrigerant into the compressing chamber 29a
and with a discharge chamber 30a defined therein to discharge the
compressed refrigerant to the outside is equipped at the lower side
of the cylinder block 29. Additionally, the cylinder head 30 is
provided, under a lower surface thereof, with at least one
heat-radiating fin 36 extending into oil flowing on the bottom of
the closed container 24. The heat-radiating fin 36 is made of a
metallic material in order to enhance heat exchange efficiency, and
a plurality of heat-radiating fins may be provided under the lower
surface of the cylinder head 30. A valve assembly 34 is equipped
between the cylinder head 30 and the cylinder block 29, and has an
intake valve 34a and a discharge valve 34b opened/closed in a
predetermined direction, guiding the refrigerant to constantly flow
in a predetermined direction (see FIG. 3).
[0031] Furthermore, the cylinder head 30 is provided, at one side
thereof, with a discharge muffler 39, and at the other side thereof
with an intake muffler 38 coupled thereto.
[0032] For this purpose, a muffler cover 39b is fastened to one
side of the cylinder head 30. Furthermore, a refrigerant pathway 37
is formed between the discharge chamber 30a and the interior of the
discharge muffler 39 to communicate between the discharge chamber
30a and the discharge muffler 39. Noise from the compressing
chamber 29a is removed while passing through a fluid pathway
defined in the discharge muffler 39. A tube 39a is extended from
the discharge muffler 39 to the outside of the compressor 20 to
guide the compressed refrigerant passing through the discharge
muffler 39 to the outside of the compressor 20. The discharge
muffler 39 is integrally formed with the cylinder head 30, and the
discharge muffler 39 and the cylinder head may, for example, be
made of aluminum. The discharge muffler 39 is spaced a
predetermined distance from the cylinder block 29.
[0033] The driving part is provided with a stator 32 and a mover
23, between which an electromagnetic force is generated to
reciprocate the piston 31 within the cylinder block 29.
[0034] The stator 32 includes an outside core 32a having a coil 35
equipped therein so that, when an electric power of a predetermined
frequency is applied to the coil 35, a magnetic flux is changed
according to the electric power, and an inside core 32b at a
position corresponding to the outside core 32a within the mover 23.
The stator 32 is securely supported by means of a holding frame 33
and the cylinder block 29.
[0035] The mover 23 has a cylindrical shape with a closed upper
side, and is equipped at the lower side thereof with a ring-shaped
permanent magnet 28 in a space between the outside core 32a and the
inside core 32b to generate an electromagnetic force between the
stator 32 and the mover 23. A piston 31 is fixed at an upper end
thereof to the center of an upper portion of the mover 23,
reciprocates along with the mover 23.
[0036] A plate spring 22 is fastened to the upper portion of the
mover 23 by a bolt 23a while passing through the mover 23. The
plate spring 22 has the center thereof fixed to the mover 23, and a
periphery fixed to the upper end of the holding frame 33.
[0037] Operation of the compressor having such a configuration as
described above will now be described with reference to FIG. 3.
[0038] First, when the piston 31 is moved upward by virtue of
cooperation of the stator 32 and the mover 23, a refrigerant
induced into the compressor 20 passes through the intake muffler
38, and is then guided into the intake chamber 30b of the cylinder
head 30. The refrigerant guided into the intake chamber 30b passes
through the intake valve 34a of the valve assembly 34, and is then
guided into the compressing chamber 29a.
[0039] Then, when the piston 31 is moved downward by virtue of the
cooperation of the stator 32 and the mover 23, the refrigerant in
the compressing chamber 29a is compressed and then discharged to
the discharge chamber 30a after passing through the discharge valve
34b of the valve assembly 34.
[0040] The high temperature, and high pressure refrigerant
discharged into the discharge chamber 30a is induced through the
refrigerant pathway 37 formed in the cylinder head 30 to the fluid
pathway in the discharge muffler 39, and is then discharged to the
outside through the tube 39a provided in the discharge muffler
39.
[0041] At this time, since the discharge muffler 39 through which
the high temperature, and high pressure refrigerant passes is
provided to the cylinder head 30 rather than to the cylinder block
29, the heat of the discharge muffler 39 is avoided from being
directly transmitted to the cylinder block 29.
[0042] Additionally, the heat of the cylinder head 30 and the
discharge muffler 39 provided to the cylinder head 30 is
transmitted to the oil through the heat radiating fins 36 formed on
the cylinder head 30, and the heat transmitted to the oil is
transmitted to the outside of the compressor 20 through the closed
container 24. Thus, the heat of the refrigerant passing through the
cylinder head 30 and the discharge muffler 39 provided to the
cylinder head 30 is prevented from being transmitted to the
compressing chamber 29a formed in the cylinder block 29.
[0043] As is apparent from the above description, the compressor
consistent with the present invention prevents the heat of the
refrigerant passing through the discharging chamber from being
transmitted to the compressing chamber, thereby preventing a
reduction of efficiency of the compressor.
[0044] Although an exemplary embodiment of the present invention
have been shown and described, it would be appreciated by those
skilled in the art that changes may be made in this exemplary
embodiment without departing from the principles and spirit of the
invention, the scope of which is defined in the claims and their
equivalents.
