Combined semiconductor refrigeration refrigerator

Abstract

A combined type semiconductor refrigeration refrigerator comprises a refrigerator body and a refrigeration temperature-difference power generation module. The refrigeration temperature-difference power generation module is arranged on the box body. A cold conduction structure is fixedly arranged on the surface of the cold end of a semiconductor refrigeration piece in the refrigeration temperature-difference power generation module. Cooling fins of a heat sink in the refrigeration temperature-difference power generation module are exposed out of the box body. The combined semiconductor refrigeration refrigerator has the beneficial effects of being efficient in refrigeration, simple in structure, small in number of mechanical components, free of noise, high in reliability, small in mounting size, low in weight, low in cost and the like and is suitable for mass industrial production

Description

technical field [0001] The invention relates to a refrigerating device, in particular to a refrigerator which adopts semi-conductor refrigerating sheets to refrigerate, and simultaneously recovers the heat generated by the refrigerating sheets to generate electricity, and can be stacked and used in combination. Background technique [0002] With the improvement and development of the performance of existing semiconductor refrigeration chips, their application fields are also expanding. Compared with traditional refrigeration equipment, it can overcome the shortcomings of mechanical compression refrigeration methods. For example, there is a risk of leakage of refrigeration media (such as Freon), which is not environmentally friendly. , high power consumption, thermal pollution and noise. The semiconductor refrigeration chip utilizes the Peltier effect of semiconductor materials. When direct current passes through a galvanic couple formed by two different semiconductor materia...

Problems solved by technology

[0005] However, this invention not only cannot recover the heat generated by the hot end of the semiconductor refrigeration sheet, but also needs to be cooled by a heat dissipation unit, which not only makes the structure of the refrigeration device more complicated, but also increases the cost to a certain extent

In terms of refrigeration efficiency, if the semiconductor refrigeration sheet is directly used for refrigeration, the conduction efficiency and effect of refrigeration will be affected due to the limitation of the area of ​​the refrigeration sheet.

On the other hand, for the use that requires multiple larger spaces, it is difficult to expand the fixed space through combination, which also limits some applications
