Heat Exchanger

摘要

A spacer portion (3) of this heat exchanger (100) includes an outer peripheral portion (3a) circumferentially provided along outer peripheral edges of bonded surfaces (1a) of cores (1) and a gap portion (3b and 3c) provided in a partial region of the circumferential outer peripheral portion, and the gap portion is provided at a position where a temperature gradient on the bonded surfaces of the cores is relatively shallow.

1. A heat exchanger comprising:
multiple cores in which flow path portions through which multiple types of fluids flow are alternately stacked; and a spacer portion arranged between bonded surfaces of the cores adjacent to each other and integrally fixed to the cores on both sides by welding, wherein the spacer portion includes an outer peripheral portion circumferentially provided along outer peripheral edges of the bonded surfaces of the cores and a gap portion provided in a partial region of the circumferential outer peripheral portion, and the gap portion is provided at a position where a temperature gradient on the bonded surfaces of the cores is relatively shallow.
