Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2014/050026
Kind Code:
A1
Abstract:
This heat exchanger is provided with flow path forming parts (40), which divide one row of first flow paths (11) into one-direction flow parts (81) formed around other-direction piping parts (22) and other-direction flow parts (82) formed around one-direction piping parts (21). The cross-sectional area of the one-direction flow parts (81) decreases toward the downstream side, and the cross-sectional area of the other-direction-flow parts (82) increases toward the downstream side. Therefore, the heat transfer promotion effect can be increased and pressure loss can be decreased.
