Description

technical field [0001] The invention relates to a refrigeration and cold storage system, in particular to a heat pipe semiconductor refrigeration and cold storage system. Background technique [0002] Semiconductor refrigeration, also known as thermoelectric refrigeration, is a refrigeration method that utilizes the thermoelectric effect (that is, the Peltier effect). [0003] The structure and principle of semiconductor refrigerators are different from liquid vaporization refrigeration. It does not require a certain working fluid circulation to achieve energy conversion, without any moving parts. The refrigeration temperature and cooling speed can be controlled by changing the size of the working current, and the adjustment and control are flexible and convenient. The operation is reversible, as long as the polarity of the current is changed, the cold and hot ends can be exchanged. [0004] In the case of large capacity, the semiconductor refrigerator consumes a lot of e...

AI Technical Summary

Problems solved by technology

[0006] The current semiconductor refrigeration device has the following problems: the cooling capacity is small and the efficiency is low; the cooling capacity is easily transferred from the cold end to the hot end of the semiconductor refrigeration block through the thermal bridge, which reduces the cooling capacity and efficiency of the system; due to the limited system capacity and Lack of power supply equipment, so it cannot be used in the wild for a long time
