In this exemplary embodiment; The cold-producing medium that is condensed that drier receiver part 130 receives through main radiator portion 110; And form being connected to this main radiator portion 110, thereby separate refrigerant gas and liquid and eliminate water with an end of main radiator portion 110 is whole.Should be appreciated that drier receiver part and main radiator portion can be integrally formed.
In this situation, first interface channel 127 forms at the downside of main radiator portion 110, makes that condensed refrigerant flows into drier receiver part 130 through passage 127 through carrying out heat exchange with cooling agent.
Than the cylindric drier receiver of routine, drier receiver part 130 has reduced volume through having with condenser 100 identical shaped drier receivers, thereby can eliminate the pipeline of separation.
Simultaneously, in this exemplary embodiment, first installing space 131 forms in drier receiver part 130, and patchhole 133 forms on corresponding to the lower cover 113 of this first installing space 131.
Drier 135 is inserted in first installing space 131 through patchhole 133, and this drier 135 has been removed the water in the cold-producing medium of supplying autonomous radiator portion 110.
That is, drier 135 is arranged in the drier receiver part 130, thereby can be replaced according to the replacement circulation through patchhole 133.
Simultaneously, filter whole formation with bag filter in drier 135 is contained in the foreign material in the cold-producing medium of drier receiver part 130.
That is, drier receiver part 130 is passed through the water that drier 135 is eliminated in the cold-producing mediums, and filters foreign material to prevent that foreign material is supplied to expansion valve 101 through filter.
Therefore, expansion valve 101 can not stopped up by the foreign material of cold-producing medium.
In this article, can locking cap 137 be arranged in the patchhole 133 preventing that the drier 135 that inserts first installing space 131 from separating, and prevent the leaking of cold-producing medium in drier receiver part 130.
In addition, crossing cold heat sink 140 forms with the bottom of main radiator portion 110 is whole between main radiator portion 110 and drier receiver part 130.Should be appreciated that cold heat sink and main radiator portion can be integrally formed.
Cross the low temperature/low-pressure refrigerant gas of cold heat sink 140 circulation-supplied flash-pots 103, and carried out cold to the cold-producing medium of supply from receiver drier part 130 through carrying out heat exchange with low temperature/low-pressure refrigerant gas.
In this exemplary embodiment; Cross cold heat sink 140 and have second interface channel 141 that forms corresponding to the upper part of drier receiver part 130, thereby from receiver drier part 130 has been supplied the cold-producing medium that liquids and gases have separated and eliminated water.
