The heat concentrator has a top surface and a bottom surface contacting a high-temperature surface of the object, and an area of the bottom surface is smaller than that of the high-temperature surface. The thermoelectric module is disposed on the top surface of the heat concentrator. The cold-side heat sink is disposed on the thermoelectric module. Heat generated by the heat source is concentrated on the heat concentrator and flows to the hot side of the thermoelectric module for increasing the heat flux (Q?) passing the thermoelectric module and the hot side temperature of the thermoelectric module. Consequently, the thermoelectric conversion efficiency (?) is improved, and the power generation of the thermoelectric module is increased.
