Abstract

The invention discloses a thermoelectric power generation device and a power generation method thereof. The device takes heat conduction oil as a heat exchange medium, is flexible to use and high in adaptability, is especially suitable for waste heat utilization occasions where a thermoelectric power generation sheet array (20) is not easy to be directly placed, and realizes maximization of powergeneration efficiency in key technologies of links of power consumption optimization of a water pump (42), power consumption optimization of a high-temperature oil pump (4) and impedance matching of the thermoelectric power generation sheet array and a load and the like. The device and method can be applied to the fields of waste heat utilization semiconductor thermoelectric power generation.

Description

technical field [0001] The invention relates to a power generation device and a power generation method thereof, in particular to a thermoelectric power generation device and a power generation method thereof. Background technique [0002] It is known that with the rapid development of science and technology, the electrification and informatization of industrial and agricultural production are increasing, and the society's demand and dependence on electric energy are getting higher and higher. , Energy depletion and other issues are becoming more and more serious. Therefore, people are actively looking for new energy sources that can replace traditional power generation. Therefore, technologies such as solar energy, wind energy, and nuclear energy have developed rapidly. At the same time, the secondary utilization technology of waste heat generated by diesel generators has also become one of the hot spots that people pay attention to. [0003] Semiconductor thermoelectric ...
