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.
- Referring to
FIG. 2 , alinear compressor 20 according to the present invention comprises a closedcontainer 24, a compressing part to intake a refrigerant from the closedcontainer 24 and to discharge the refrigerant after compressing the refrigerant, and a driving part to provide a compressing force to the compressing part. - The compressing part is provided with a
cylindrical cylinder block 29 having acompressing chamber 29 a defined therein, and with a rod-shaped piston 31 equipped in thecompressing chamber 29 a of thecylinder block 29 to linearly reciprocate up and down within thecompressing chamber 9 a. Thecylinder block 29 is supported by asupport spring 25. - A
cylinder head 30 with anintake chamber 30 b defined therein to intake the refrigerant into thecompressing chamber 29 a and with adischarge chamber 30 a defined therein to discharge the compressed refrigerant to the outside is equipped at the lower side of thecylinder block 29. Additionally, thecylinder head 30 is provided, under a lower surface thereof, with at least one heat-radiatingfin 36 extending into oil flowing on the bottom of the closedcontainer 24. The heat-radiatingfin 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 thecylinder head 30. Avalve assembly 34 is equipped between thecylinder head 30 and thecylinder block 29, and has anintake valve 34 a and adischarge valve 34 b opened/closed in a predetermined direction, guiding the refrigerant to constantly flow in a predetermined direction (seeFIG. 3 ). - Furthermore, the
cylinder head 30 is provided, at one side thereof, with adischarge muffler 39, and at the other side thereof with anintake muffler 38 coupled thereto. - For this purpose, a
muffler cover 39 b is fastened to one side of thecylinder head 30. Furthermore, arefrigerant pathway 37 is formed between thedischarge chamber 30 a and the interior of thedischarge muffler 39 to communicate between thedischarge chamber 30 a and thedischarge muffler 39. Noise from thecompressing chamber 29 a is removed while passing through a fluid pathway defined in thedischarge muffler 39. Atube 39 a is extended from thedischarge muffler 39 to the outside of thecompressor 20 to guide the compressed refrigerant passing through thedischarge muffler 39 to the outside of thecompressor 20. Thedischarge muffler 39 is integrally formed with thecylinder head 30, and thedischarge muffler 39 and the cylinder head may, for example, be made of aluminum. Thedischarge muffler 39 is spaced a predetermined distance from thecylinder block 29. - The driving part is provided with a
stator 32 and amover 23, between which an electromagnetic force is generated to reciprocate thepiston 31 within thecylinder block 29. - The
stator 32 includes anoutside core 32 a having acoil 35 equipped therein so that, when an electric power of a predetermined frequency is applied to thecoil 35, a magnetic flux is changed according to the electric power, and aninside core 32 b at a position corresponding to theoutside core 32 a within themover 23. Thestator 32 is securely supported by means of aholding frame 33 and thecylinder block 29. - The
mover 23 has a cylindrical shape with a closed upper side, and is equipped at the lower side thereof with a ring-shapedpermanent magnet 28 in a space between theoutside core 32 a and theinside core 32 b to generate an electromagnetic force between thestator 32 and themover 23. Apiston 31 is fixed at an upper end thereof to the center of an upper portion of themover 23, reciprocates along with themover 23. - A
plate spring 22 is fastened to the upper portion of themover 23 by abolt 23 a while passing through themover 23. Theplate spring 22 has the center thereof fixed to themover 23, and a periphery fixed to the upper end of theholding frame 33. - Operation of the compressor having such a configuration as described above will now be described with reference to
FIG. 3 . - First, when the
piston 31 is moved upward by virtue of cooperation of thestator 32 and themover 23, a refrigerant induced into thecompressor 20 passes through theintake muffler 38, and is then guided into theintake chamber 30 b of thecylinder head 30. The refrigerant guided into theintake chamber 30 b passes through theintake valve 34 a of thevalve assembly 34, and is then guided into the compressingchamber 29 a. - Then, when the
piston 31 is moved downward by virtue of the cooperation of thestator 32 and themover 23, the refrigerant in the compressingchamber 29 a is compressed and then discharged to thedischarge chamber 30 a after passing through thedischarge valve 34 b of thevalve assembly 34. - The high temperature, and high pressure refrigerant discharged into the
discharge chamber 30 a is induced through therefrigerant pathway 37 formed in thecylinder head 30 to the fluid pathway in thedischarge muffler 39, and is then discharged to the outside through thetube 39 a provided in thedischarge muffler 39. - At this time, since the
discharge muffler 39 through which the high temperature, and high pressure refrigerant passes is provided to thecylinder head 30 rather than to thecylinder block 29, the heat of thedischarge muffler 39 is avoided from being directly transmitted to thecylinder block 29. - Additionally, the heat of the
cylinder head 30 and thedischarge muffler 39 provided to thecylinder head 30 is transmitted to the oil through theheat radiating fins 36 formed on thecylinder head 30, and the heat transmitted to the oil is transmitted to the outside of thecompressor 20 through theclosed container 24. Thus, the heat of the refrigerant passing through thecylinder head 30 and thedischarge muffler 39 provided to thecylinder head 30 is prevented from being transmitted to the compressingchamber 29 a formed in thecylinder block 29. - 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.
- 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.
