。Prior art and its problems A method of converting thermal energy into electrical energy by the Seebeck effect using two types of fluids with different temperatures is as follows.
It is publicly known. For example, as schematically shown in Figure 2, the temperature (
An aluminum pipe (3) with a hot water flow path (1) of temperature (TC) and an aluminum pipe (7) with a cold water flow path (5) of 99 digits are connected to a copper plate (9). and (11), and a thermoelectric power generation device arranged facing each other via a thermoelectric conversion element (13) has been proposed. In this device, the tube (3)
and (7) are required to have high thermal conductivity, but the three sides other than the one on which the thermoelectric conversion element (13) is arranged are required to have heat insulation properties, so the heat insulating material layer (15) and ( 17) is required and the equipment is expensive. Moreover, as is clear from the temperature profile shown in FIG. 3, the effective temperature range (ΔT) applied to the thermoelectric conversion element (13) is small, which means that the tube (
3) and the tube (7) is not effectively converted into electrical energy, indicating that energy loss is large.
