Stacked type multi-flow heat exchanger |
(57) A stacked type multi-flow heat exchanger (1) includes a plurality of heat transfer
tubes (2) and fins (3) stacked alternately, and upper front (31a) and an upper rear
tank (31b), a lower front (32a) and a lower rear tank (32b). The heat exchanger (1)
includes partitions (33,34) provided at the lower front and rear tanks (32a,b), respectively,
and a communication path (36) communicating between the same side ends of the lower
front and rear tanks (32a,b). A communication header (38) forming the communication
path (36) is formed integrally with the outermost heat transfer tube (2b). Liquid
refrigerant flows at a greater amount through the central portion of the heat exchanger
core (1a), whereas high temperature refrigerant flows through the edge portions of
the heat exchanger core (1a). A uniform temperature distribution of air having passed
through the heat exchanger (1) may be achieved.
