To enable uniform pressurization superior in thermal contact in a thermoelectric module, a heat exchanger for heating and a heat exchanger for cooling by filling the gaps among the heat exchanger for heating, the thermoelectric module and the heat exchanger for cooling with helium gas, and using a pressurizing means which uses fluid as the pressurizing medium.
A thermoelectric power generation unit 1 is provided with a nine-layered laminate, constituted of plate fin type heat exchangers 3 for heating, thermoelectric power generating modules 2 and plate fin type heat exchangers 4 for cooling. These apparatuses are encapsulated in a box-type sealing material, which is filled with helium gas. As a pressuring means, air pressure in a bellows is changed, and the pressure applied to the nine-layered laminate encapsulated in the seal material is adjusted. As a result, thermal contact (thermal efficiency) among the heat exchangers 3, the thermoelectric modules 2 and the heat exchangers 4 is improved. These apparatuses are pressurized by using a pressurizing means 9 which uses fluid such as air for the pressurizing medium, so that uniform pressurization is enabled.
