Patent ID: 11874034

Abstract:
A heat exchanger includes a heat transfer unit (HTU) including a heat transfer channel portion (HTCP) and auxiliary heat transfer portions (AHTPs). The HTCP and the AHTPs extend in a direction and are disposed in another direction being perpendicular to the direction. One of the AHTPs is an AHTP adjacent to the HTCP in another direction. When viewed from the direction, the AHTP is at an end of the HTU in another direction. A distance from the AHTP to the HTCP in another direction is defined as a length, in a case where the HTU further includes a plurality of HTCPs, the length is larger than a distance between adjacent ones of the HTCPs in another direction, and in a caser where the heat exchanger further includes a plurality of HTUs, the length is larger than a distance between the HTUs adjacent to each other in a direction different.
