Description

technical field [0001] The invention relates to performance testing technology of temperature difference materials, in particular to a thermoelectric conversion performance testing system and method of temperature difference materials, belonging to the field of thermoelectric conversion. Background technique [0002] Thermoelectric power generation is a green and environmentally friendly power generation method. Thermoelectric power generation technology is widely used because of its simple structure, sturdy and durable, no moving parts, no noise, long service life, and reasonable use of solar energy, geothermal energy, and industrial waste heat. research and application. However, with the development of thermoelectric power generation technology, how to accurately measure the performance of thermoelectric materials has become a concern. [0003] In 2006, Chen Yuncheng of Xiamen University proposed a semiconductor thermoelectric power generation module performance test plat...

AI Technical Summary

Problems solved by technology

The test platform uses air cooling for heat dissipation, which cannot fully dissipate heat, and the heat dissipation effect without water cooling is excellent

In addition, the temperature of the hot and cold ends of the thermoelectric power generation module cannot be measured, and it is difficult to obtain information such as the optimal working temperature and temperature difference of the material
