Abstract

The invention discloses a temperature difference power generation system and a working method thereof. The temperature difference power generation system comprises a temperature difference power generation set, the temperature difference power generation set comprises a first temperature difference power generation chip, a heat dissipation structure and a black heat dissipation sheet, the hot end of the first temperature difference power generation chip is connected with the black heat dissipation sheet, and the cold end of the temperature difference power generation chip is connected with the heat dissipation structure. According to the temperature difference power generation system, the hot end of the temperature difference power generation chip is connected with the black cooling fin to absorb heat to increase the temperature, an original method for increasing the temperature by absorbing heat through heat radiation is abandoned, and an original method for increasing the temperature by absorbing heat through single heat conduction is improved. The cold end is connected with the heat dissipation structure, the temperature difference between the two ends of the thermoelectric power generation chip under limited hot and cold end temperatures can be increased, and the power generation efficiency is improved. By means of the heat dissipation structure power generation system, heat in an area with the large day and night temperature difference can be effectively utilized.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a thermoelectric power generation system and a working method thereof. Background technique [0002] In many regions with large temperature difference between day and night, such as semi-arid and arid regions, the intensity of solar radiation is high, and the sand and stones on the surface absorb a lot of heat, but the heat is eventually lost in the form of heat energy, causing waste, and the heat has not been utilized so far. [0003] Thermoelectric power generation refers to the effective utilization of low-grade energy through the direct conversion of thermal energy and electrical energy. The use of thermothermal power generation technology is expected to be used for heat utilization in areas with large temperature differences between day and night. In the existing technology, a variety of technologies using temperature difference power generation such as seawater temperature...
