Receiver-drier for condensor of vehicle air conditioner

The present invention relates to a receiver provided in a condenser for a vehicle, and more particularly, to a receiver provided in a condenser in which a condenser is formed at an upper part and a subcooling part is formed in a lower part. The desiccant in the receiver includes a header tank and a receiver tank. The present invention relates to a condenser receiver of a vehicle air conditioner, which not only prevents the possibility of blocking the inlet of the connecting pipe to be connected.

In general, a condenser employed in a vehicle air conditioner is a heat exchanger that converts a refrigerant in a gaseous phase compressed at high temperature and high pressure into a liquid refrigerant by heat exchange with lower ambient air. The condenser has a structure in which a tube and a heat dissipation fin are alternately stacked between a pair of header tanks to form a core part, and the inlet and outlet pipes are installed in the header tank so that refrigerant flows in and out. A receiver drier is coupled to one header tank of the pair of header tanks to store a liquid refrigerant. The receiver is provided with a desiccant and a filter. The desiccant removes moisture contained in the liquid refrigerant in the receiver, and removes foreign substances contained in the refrigerant in the liquid due to the filter.

In the condenser having the configuration described above, baffles are alternately installed in the header tanks, so that a meandering refrigerant passage may be formed by the header tank and the tubes by separating the header tank into a plurality of staggered compartments. . The refrigerant passage may be divided into a condensation unit in which gaseous refrigerant introduced from an inlet tube installed in the other header tank of the pair of header tanks is liquefied while moving in the tubes, and a subcooling unit cooling the condensed refrigerant as described above. Can be.

On the other hand, as a conventional technique, a condenser is located in the upper part of the core part, and the technique in which the supercooling part is located in the lower part of the core part is a receiver (public number: JP2003-302126) disclosed in Japan.

However, a receiver (published number: JP2003-302126) disclosed in Japan has a receiver cap to facilitate attachment and detachment of the receiver cap when replacing desiccant or the like provided inside the receiver. The assembly was taken at the upper end. At this time, the filter is a receiver cap (cap) and the filter is separated and installed in the lower portion of the receiver, and also a separate support member for fixing the filter separated from the receiver cap (cap) is installed. In other words, the receiver (published number: JP2003-302126) disclosed in Japan is simplified because the receiver cap and the filter are integrally formed because the receiver cap and the filter must be applied separately up and down. There is a disadvantage in that the advantage of the structure is complicated.

The present invention simplifies the configuration by placing the filter-integrated receiver cap on the upper end of the receiver tank, all liquid refrigerant flowing into the receiver tank passes through the filter, the desiccant for supporting the lower end of the desiccant on the lower end of the receiver tank It is to provide a receiver that is provided with a supporting member to prevent the disadvantage that the lower end of the desiccant blocking the connection tube inlet connecting the receiver tank and the header tank.
