ABSTRACT:
An integrated condenser/receiver includes a multi-pass heat exchanger core, an elongated receiver housing, and a refrigerant conduit to direct refrigerant between the receiver housing and the multi-pass heat exchanger core. The heat exchanger core includes an elongate header extending along an axis, a plurality of tubes extending parallel to each other and transverse to the axis to direct a refrigerant through the core, with the tubes spaced along the header and having ends received therein to direct refrigerant to and from the header, and at least one baffle in the header to separate the header into a first portion that receives refrigerant from a first set of the tubes and a second portion that directs refrigerant to a second set of the tubes. Each of the set of tubes defines a refrigerant pass through the core. The receiver housing is mounted to the core, with the second set of tubes located between the receiver housing and the first set of tubes. The receiver housing includes a first port connected to the second portion. The refrigerant conduit is connected to the first portion and to the receiver housing to direct refrigerant between the first portion and the receiver housing.
