Document Type and Number:
WIPO Patent Application WO/2022/030566
Kind Code:
A1
Abstract:
An attachment structure in which a flange 2 of a heat exchanger and a casing 3 form a metal touch 12, wherein a liquid is prevented from leaking out from a hole edge section of a flow path hole 6. A protruding step surface 8 is formed at the hole edge section of the flow path hole 6 in the flange 2 of the heat exchanger, the protruding step surface 8 projecting farther toward the casing 3 than does the surface of the metal touch 12. The flange 2 is thereby press-fitted firmly to the casing 3, and a liquid is thereby prevented from leaking out from the hole edge of the flow path hole 6.
