Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to an air-cooled refrigeration system and a semiconductor refrigerator. Background technique [0002] The refrigeration principle of semiconductor refrigerators is completely different from that of ordinary compressor refrigerators. When the semiconductor chip is powered on, it uses the difference in the energy level of the charge carrier between the two materials to achieve cooling / heating. The semiconductor refrigerator utilizes the Peltier effect and has low power consumption. Since there is no compressor and other components, the product is small, light and easy to carry. However, semiconductor refrigerators also have small cooling capacity, large heat dissipation, poor cooling speed, and poor cooling effect. problem has been difficult to solve. [0003] At present, most semiconductor refrigerators on the market generally install semiconductor chips at a suitable position...
