Description

(1) Technical field

[0001] The invention relates to a semiconductor refrigeration system, which includes: a semiconductor refrigeration sheet, which has a heat effect surface and a cold effect surface; a refrigeration end exchanger, in which a refrigerant circulates inside, and one side is arranged close to the cold effect surface; and cold utilization equipment , connected to the refrigerating end exchanger through a refrigerant circulation pipeline. (2) Background technology

[0002] At present, it is widely used in the field of refrigeration, and the cooling method with better effect is to use the low-pressure evaporation characteristics of the refrigerant, which has the characteristics of large latent heat, high stability, good condensation, and suitable condensation pressure. Combined with the compression refrigerator to complete the refrigeration, Relying on the function of the compressor to increase the pressure of the refrigerant to realize the refrigeration cycle, i...

Embodiment Construction

[0030] Instructions attached figure 1 with 2 A peltier refrigeration system is shown, comprising:

[0031] The semiconductor cooling chip 4 has a thermal effect surface and a cold effect surface;

[0032] The cooling end exchanger 3 has a refrigerant circulating inside, and one side is arranged close to the cooling effect surface;

[0033] The cold utilization equipment 7 is connected to the refrigerating end exchanger through a refrigerant circulation pipeline;

[0034] The sealing cover 5 is used for the refrigeration element group of the semiconductor refrigeration chip to be isolated from the outside airtight.

[0035] The connection between the sealing cover and the semiconductor refrigeration chip requires different sealing levels due to the different internal fillings. If the internal filling is dry air or other gases, the sealing can be achieved by conventional welding and bonding. Level, even if there is an air leak, the water vapor carried by a small amount of ga...
