Patent ID: 7077193

Claim:
A compound type heat exchanger, comprising: a plurality of heat exchanging passage members each formed to allow passage of a heat exchanging medium therein, the heat exchanging passage members being juxtaposed to each other; a plurality of fins each interposed between the adjoining heat exchanging passage members so as to form a lamination having the heat exchanging passage members and the fins stacked alternately; a pair of header pipes arranged on both ends of the heat exchanging passage members and also connected to respective ends of the heat exchanging passage members; partition walls each arranged in the header pipes thereby to divide spaces inside the header pipes in a direction perpendicular to a longitudinal direction of the header pipes; and a pseudo heat exchanging passage member located at a position corresponding to the partition walls, wherein two of the fins adjoin the pseudo heat exchanging passage member wherein the lamination and the header pipes are divided in a direction perpendicular to a laminating direction at a boundary containing the partition walls and the pseudo heat exchanging passage member to form a first heat exchanging unit and a second heat exchanging unit, wherein there is a space between one of the fins adjoining the pseudo heat exchanging passage member and the pseudo heat exchanging passage member.
