Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2022/196192
Kind Code:
A1
Abstract:
Provided is a heat exchanger whereby corrosion of the metallic heat-transfer layers can be simply and reliably prevented. The present invention is directed to a heat exchanger provided with: an outer envelope (1) through the interior of which a heat exchange medium circulates; and inner fins (2) that are housed in the outer envelope (1) in a state in which a portion of the inner fins are in contact with the inner surface of the outer envelope 1. This heat exchanger is configured so that: the outer envelope (1) is constituted by an externally-enveloping laminate material (L1) in which on at least one side of a metal layer, a resin polymer layer is laminated; and the inner fins (2) are constituted by an internal-core laminate material (L2) in which on both sides of a metallic heat-transfer layer (61), resin hot-melt adhesive layers (62) are respectively laminated. On a lateral edge (7a) of the internal-core laminate material (L2), a thin edge section (7) is formed, and the thin edge section (7) includes: a lateral edge (6a) of the heat-transfer layer (61); heat-transfer-layer lateral-edge laminate sections (72) that are made of a resin and are laminated on both sides of the lateral edge (6a); and a heat-transfer-layer end-surface cover section (73) that is made of a resin and covers an end surface (6b) of the heat-transfer layer (61).
