Supercooling maintaining device used for pulse thermoelectric refrigeration and capable of recovering heat

Abstract

The invention discloses a supercooling maintaining device used for pulse thermoelectric refrigeration and capable of recovering heat. The supercooling maintaining device comprises a thermoelectric refrigeration mechanism, a rotating mechanism, a thermoelectric power generation mechanism and a mounting shell; the thermoelectric refrigeration mechanism comprises a plurality of sets of thermoelectric refrigeration units, the thermoelectric refrigeration units are mounted on the rotating mechanism, and a cold medium conduction block is mounted at one side of the mounting shell; when one thermoelectric refrigeration unit rotates to be communicated with an external pulse current on the cold medium conduction block, transient ultracold on the basis of normal refrigeration can occur, then the thermoelectric refrigeration unit is subjected to retaliatory heat feedback, and the rotating mechanism moves the thermoelectric refrigeration unit with the retaliatory heat feedback from the position where the thermoelectric refrigeration unit is in butt joint with the heat conduction medium block to the position where the thermoelectric refrigeration unit is in butt joint with the thermoelectric power generation mechanism; and meanwhile, the next group of thermoelectric refrigeration unit is communicated with the external pulse current on the cold medium conduction block to continuously carry out transient ultracold on the basis of normal refrigeration of the thermoelectric refrigeration unit, and the cycle is carried out, so that the refrigeration capacity of thermoelectric refrigeration is enhanced, continuous and efficient refrigeration is realized, and heat generated by thermoelectric refrigeration is recycled.

Description

technical field [0001] The invention relates to the technical field of thermoelectric refrigeration, in particular to a supercooling maintenance device for pulse thermoelectric refrigeration capable of heat recovery. Background technique [0002] At present, the refrigerators on the market are mainly divided into vapor compression cooling and semiconductor refrigerators. Vapor compression cooling needs to use refrigerant as the medium, which will cause certain damage and impact on the environment; The cooling device, also known as thermoelectric cooler, has the characteristics of no noise, no vibration, no refrigerant, small size, light weight, etc., and is reliable in operation, easy to operate, and easy to adjust the cooling capacity. The principle is to connect two different metals with a conductor, and when direct current is connected, the temperature at one joint will decrease, and the temperature at the other joint will increase. [0003] The so-called thermoelectric ...

Problems solved by technology

[0004] The existing semiconductor refrigerators still have the following problems to be solved: 1. The DC semiconductor refrigerator has a small cooling coefficient and the cooling temperature is limited; 2. The traditional semiconductor refrigerator uses a conductor to connect two different metals, and when DC is connected, one contact 3. The heat generated by the semiconductor refrigerator cannot be recycled, which consumes a lot of resources
