Heat exchange device

Abstract

A heat exchange device includes a heat exchanger disposed in connection with at least one of a heat-dissipation electrode and a heat-absorption electrode, between which a plurality of thermoelectric elements is connected in series, via an insulating resin layer, which is composed of an epoxy resin or polyimide resin doped with fillers having high thermal conductivity, without intervention of a substrate. The heat exchanger corresponds to a plurality of corrugated fins which are constituted of a plurality of joint regions joining with one of the heat-dissipation electrode and heat-absorption electrode and a plurality of non-joint regions projecting externally from a plurality of gaps formed between the joint regions adjacently aligned together, wherein the joint regions and non-joint regions are alternately aligned. Thus, it is possible to achieve high reliability by reducing thermal resistance and thermal stress while increasing the maximum heat absorption coefficient (Qmax).
