Patent ID: 7036571

Claim:
A compound type heat exchanger, comprising: a core part having a plurality of heat exchanging tubes each formed to allow passage of a heat exchanging medium therein, the heat exchanging tubes being juxtaposed to each other, and a plurality of fins each interposed between the adjoining heat exchanging tubes so that the heat exchanging tubes and the fins are stacked alternately; a pair of header pipes arranged on both ends of the heat exchanging tubes and connected to respective ends of the heat exchanging tubes; a pseudo heat exchanging passage member having a substantially L-shaped section and being positioned within the core part so that a width of a front edge of the pseudo heat exchanging passage member is approximately equal to a width of one of the heat exchanging tubes and one of its associated fins; and partition walls each arranged in the header pipes so as to be close to the pseudo heat exchanging passage member thereby to divide spaces inside the header pipes, wherein the pseudo heat exchanging passage member divides the core part and the partition walls divide the header pipes to form a first heat exchange unit and a second heat exchange unit.
