Document Type and Number:
WIPO Patent Application WO/2017/195588
Kind Code:
A1
Abstract:
A stack type heat exchanger is provided with a heat exchange section (10) for exchanging heat between first fluid and second fluid. The heat exchange section is formed by stacking and joining a plurality of plate-shaped members (11). A plurality of first fluid passages (12) through which the first fluid flows and a plurality of second fluid passages (13) through which the second fluid flows are formed between the plurality of plate-shaped members. The plurality of first fluid passages and the plurality of second fluid passages are arranged next to each other in the direction in which the plurality of plate-shaped members are stacked. The first and second flow passages have upper passages (12b, 13b) and lower passages (12c, 13c) and are configured so that the first fluid or the second fluid having flowed through the upper passages can make a U-turn and flow through the lower passages. Inner fins (30, 40) are arranged in the first and second fluid passages, the inner fins (30, 40) joining adjacent plate-shaped members and promoting the heat exchange between the first fluid and the second fluid. Partitions (32, 42) for separating the upper passages and the lower passages are formed by the inner fins.
