[0003] At present, the experiment on the principle of semiconductor heating and cooling is mainly done through the power-on demonstration of the existing semiconductor cooling chips on the market. Students can only feel the temperature changes by touching the semiconductor cooling chips, and they do not have an intuitive understanding of the performance of semiconductor cooling and heating.

[0004] Moreover, although the current semiconductor refrigeration technology has made considerable progress in single refrigeration, it has not made good use of the performance of semiconductor refrigeration and heating.

The working intensity of the semiconductor temperature control experimental system is generally displayed by the power value of semiconductor refrigeration or heating, which does not save energy.
