Abstract
A heat exchanger includes a pair of header tanks (4) placed in parallel to each other in a plane; a row of parallel tubes (2) placed in the plane and connected at opposite ends to the header tanks; a plurality of partitions (6, 6') provided in the header tanks to divide each header tank into a plurality of compartments (8a) along the length of the header tank thereby forming a plurality of refrigerant passages (2A, 2B) each consisting of a plurality of multitube paths each having a plurality of the parallel tubes; and a pair of additional tanks (7) each attached to each of the header tanks to form a chamber (8) which communicates with the refrigerant passages through ports formed on the header tank whereby refrigerant is distributed into the plurality of refrigerant passages to provide the reduced flow resistance of refrigerant.
