Patent ID: 7444822

Claim:
A heat exchanger comprising: a heat radiation side heat exchange body and a heat absorption side heat exchange body; a thermoelectric conversion element module interposed between the heat radiation side heat exchange body and the heat absorption side heat exchange body, the thermoelectric conversion element module being respectively configured of a plurality of heat radiation side electrodes, a plurality of thermoelectric conversion elements, and a plurality of heat absorption side electrodes; a heat radiation side insulating layer which is interposed between the heat radiation side electrodes of the thermoelectric conversion element module and the heat radiation side heat exchange body; and a heat absorption side insulating layer which is interposed between the heat absorption side electrodes of the thermoelectric conversion element module and the heat absorption side heat exchange body, wherein at least one of the heat radiation side insulating layer and the heat absorption side insulating layer is a resin which is fusion bonded to the adjacent heat exchange body by heating and pressing such that the melted resin enters cavities and flaws in a surface of the heat exchange body.
