Thermoelectric power generation experimental device

Abstract

The invention relates to a thermoelectric power generation experimental device, which comprises a heating device, a thermoelectric battery and a water cooling circulating device in turn from bottom totop. The temperature difference power generation experiment device of the invention utilizes a temperature control probe, a temperature control meter and a solid state relay to precisely control thetemperature on the upper side and the lower side of the temperature difference power generation chip, so that the temperature on the upper side and the lower side of the temperature difference power generation chip is kept stable, heat dissipation is reduced, and measurement accuracy is improved. The thermoelectric power generation experiment device of the invention maintains the low temperature of the cold end of the thermoelectric power generation sheet constant through a water cooling circulating system, and reduces the temperature dissipation of the hot end of the thermoelectric power generation sheet through a heat insulation asbestos material. The experimental device is suitable for the teaching of college physics experiment because of its rapid temperature rise and accurate temperature difference measurement.

Description

technical field [0001] The invention relates to the technical field of thermoelectric power generation, in particular to an experimental device for thermoelectric power generation. Background technique [0002] Thermoelectric power generation is a technology that uses thermal energy to generate electricity, which can directly convert thermal energy into electrical energy. Different from mainstream power generation methods, thermoelectric power generation has no waste emissions, no noise, safe, reliable and stable work, and is a way to recover and reuse heat energy. But for a long time, the application of thermoelectric power generation technology has been limited to high-tech, military and aerospace fields. [0003] In the current college physics experiment teaching, the existing experimental devices are complex in structure and cumbersome in operation, which is not conducive for students to observe the phenomenon of thermoelectric power generation and master the basic prin...
