The degree of improvement was seen. It was also confirmed that the efficiency difference decreases when the temperature difference is large. this is,
It is considered that the difference in the heat input amount appears as it is, and when the relationship between the temperature difference and the heat input is actually shown in the figure, it is better to take anti-freezing measures as shown in FIGS. 9 and 10. The amount of heat input is smaller than when no preventive measures are taken. This phenomenon is considered to be caused by freezing, and it is considered that freezing causes another heat flow field through other paths in addition to the one passing through the inside of the element. Further, when the average temperature of the thermoelectric power generation element rises, the substance attached to the surface of the thermoelectric generation element as frost melts into a completely iced state, and it solidifies under the power generation element. Here, it is considered that the heat source takes heat to melt the ice, resulting in an increase in heat input.

It can be seen that the heat input value is smaller than that of. As mentioned above,
In the example of the present invention, even if liquid nitrogen is used as the low-temperature heat source, the thermoelectric power generation element does not freeze, and the power generation efficiency is improved.
