PROBLEM TO BE SOLVED: To improve a yield in manufacturing a heat exchanger by securing insulation between a heat exchanging member and a thermoelectric converting element module. SOLUTION: Resins 5, 6 as insulating layers are placed between heat radiation-side and heat absorption-side heat exchanging members 2, 3 and between heat radiation-side and heat absorption-side electrodes 41, 42 of the thermoelectric converting element module 4, respectively. The resin 5 is welded to the heat radiation-side heat exchanging member 2, and the resin 6 is welded to the heat absorption-side heat exchanging member 3. A material of the resin 5, 6 is, for example, thermosetting plastic. The thermosetting plastic is softened by heating, and then hardened. In welding the resin 5, 6 to the heat exchanging members 2, 3, the heat exchanging members 2, 3 and the resins 5, 6 are heated and pressed. Then, the resins 5, 6 are softened and intrude into cavities and scratches on surfaces of the heat exchanging members 2, 3. The resins 5, 6 intruding in the cavities and scratches are hardened to bury the cavities existing on the surfaces of the heat exchanging members 2, 3. COPYRIGHT: (C)2006,JPO&NCIPI |
