However, there are also certain defects in the semiconductor thermoelectric power generation device that provides high-temperature liquid as a heat source in the prior art: hot water is usually used as a heat source for high-temperature liquid in the prior art, but even if heat preservation measures are taken, due to the need to consume heat when generating electric energy, Therefore, the temperature of the hot water will drop, resulting in a decrease in the temperature of the hot end of the semiconductor power generation chip, and the temperature difference between the hot end and the cold end will continue to decrease.

At present, there is no use of the temperature of the exhaust pipe of the automobile to generate electricity, so as to achieve the goal of providing stable and sufficient driving voltage to the components to be driven for a long time
