Abstract:
1. A heat exchanger comprising: a heat exchange section having a core comprising a high temperature fluid channel in which a high temperature fluid flows and a low temperature fluid channel in which a low temperature fluid flows, wherein a heat exchange between the high temperature fluid and the low temperature fluid is conducted; a housing comprising a housing body having a first and a second planar wall and a third wall between said first and said second planar wall, said first and said second planar wall being substantially parallel to each other and each having a flanged portion extending outwardly along an end opposite to the third wall, and a cover member, covering the outside of the heat exchange section except for a high temperature fluid inlet side and outlet side, said cover member being joined at a periphery thereof to the flanged portions of said first planar wall and said second planar wall to form a first joint and a second joint, respectively; and a heat resistant filler intervening between the heat exchange section and the housing; and a heat deformation absorbing mechanism formed by bending at least one of the first joint or second joint substantially perpendicular to the cover member.
