Classification: CPC F  Y | IPC F  H

Claim 0:
1. A heat exchanger comprising:
at least one outer packaging material wherein
the at least one outer packaging material are provided with a heat medium inlet and a heat medium outlet, wherein a heat medium flows into an inner space of the at least one outer packaging material via the heat medium inlet, flows through the inner space, and flows out of the at least one outer packaging material via the heat medium outlet; and
an inner core material arranged in the inner space of the outer packaging material,
wherein each of the at least one outer packaging material is constituted by an outer packaging laminate material including a heat transfer layer, a resin thermal fusion layer provided on an inner surface side of each heat transfer layer, and a resin coating layer provided on an outer surface side of each heat transfer layer and the resin thermal fusion layers of the outer packaging laminate material are integrally joined to each other along a peripheral edge portion of the outer packaging laminate material,
wherein each resin coating layer has a melting point higher than that of the resin thermal fusion layer of the outer packaging laminate material in each of the at least one outer packaging material by 10° Celsius or more;
wherein the resin thermal fusion layer of the at least one outer packaging material and a resin thermal fusion layer of the inner core material are made of the same polyolefin-based resin;
wherein the inner core material is constituted by an inner core laminate material formed in a corrugated plate shape including a heat transfer layer and resin thermal fusion layers provided on each surface side of the heat transfer layer, and wherein the inner core laminate material includes concave and convex portions,
wherein the heat transfer layer of the outer packaging laminate material of each of the at least one outer packaging material and the heat transfer layer of the inner core laminate material are comprised of aluminum foil;
wherein resin thermal fusion layers of a concave portion bottom and a convex portion top of the inner core material and the resin thermal fusion layer of the at least one outer packaging material are integrally joined,
wherein the resin thermal fusion layer at the bottom of the concave portion of the inner core material and the resin thermal fusion layer of the at least one outer packaging material are thermally fused and polyolefin-based resin layers are interposed entirely between the heat transfer layer of the inner core material and the heat transfer layer of the at least one outer packaging material, and
wherein the resin thermal fusion layer at the top of the convex portion of the inner core material and the resin thermal fusion layer of the at least one outer packaging material are thermally fused and polyolefin-based resin layers are interposed entirely between the heat transfer layer of the inner core material and the heat transfer layer of the at least one outer packaging material.
