ABSTRACT:
A receiver-integrated condenser for a refrigerating system for use in an automotive vehicle is disclosed. The condenser is composed of a heat exchanging core having many tubes extending horizontally in which refrigerant is cooled down and condensed, a pair of header tanks elongated vertically and connected to both ends of the tubes, and a refrigerant receiver for reserving liquid refrigerant therein integrally connected to one of the header tanks which has an inlet joint for receiving overheated refrigerant from a compressor. The inner space of the header tank to which the receiver is connected is divided by a separator into an upper space for receiving the overheated refrigerant and a lower space for receiving refrigerant cooled down in the heat exchanging core. The receiver is connected integrally to the header tank so that it does not overlap with the upper space of the header tank in order to minimize heat transfer from the upper space to the receiver. Thus, the liquid refrigerant reserved in the receiver does not evaporate therein, and a whole space of the receiver is utilized for reserving the liquid refrigerant therein, enabling to fill additional refrigerant in the system without causing a sub-cool temperature rise.
