Abstract

Provided is a heat exchanger capable of improving the flowability of a heat exchange medium in an inlet / outlet forming part. The present invention relates to a heat exchanger provided with: a heat transfer unit (2) configured as a heat exchange flow path (20) through which a heat exchange medium (L) flows in a hollow section; and inlet / outlet forming parts (1a, 1b), the interior of which is connected to the heat exchange flow path (20) in a communicating manner and in which an inlet / outlet (15) through which the heat exchange medium (L) flows in and out is formed. At least a portion of the outer surface portion of the heat transfer portion (2) is configured from a cover sheet (6) which is a laminated material obtained by providing a resin cover layer on at least one surface side of a metal heat transfer layer, and the outer dimension thickness (T1) of the inlet / outlet forming portions (1a, 1b) is formed to be thicker than the outer dimension thickness (T2) of the heat transfer portion (2).

Description

technical field [0001] The present invention relates to a heat exchanger having a laminated material in which a metal heat transfer layer and a resin coating layer are laminated on an outer surface. Background technique [0002] Hybrid vehicles (HEV), electric vehicles (EV), and the like are equipped with battery devices that supply electric power for driving electric motors. As such a battery device, a battery device in the form of a battery pack formed by connecting a plurality of small cells including various secondary batteries such as lithium secondary batteries in series or in parallel is generally used. In particular, in recent years, in order to extend the cruising distance of electric vehicles, a plurality of battery packs have been combined in series or in parallel to further increase the capacity of battery devices. [0003] On the other hand, since the performance and life of lithium secondary batteries widely used as battery devices vary greatly depending on th...
