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

Embodiment 2

[0037] The thermoelectric refrigeration mechanism is set to include 4 sets of thermoelectric refrigeration units, and materials such as lg-6 isostatic graphite, heat insulation board, 6061 aluminum, semiconductor refrigerator (TEC), and semiconductor thermoelectric generator (TEG) are used to further improve the model. On this basis, the physical object was built, and some experiments were carried out on the basis of the physical object, which preliminarily verified the feasibility of the principle design of this project.

[0038] Estimated energy consumption calculation:

[0039] Electric energy recovery rate: α=TEG output power / external input pulse current power=66.29 / 1040.70*100%=6.37%;

[0040] Subcooling degree = (DC optimal steady-state temperature - transient supercooling temperature) / optimal steady-state temperature = (260K-249.41K) 260K*100%=4.07% (calculated in degrees Celsius);

[0041] Original cooling efficiency = (other parts cooling object temperature - stead...

Abstract

The invention discloses a supercooling maintenance device for pulse thermoelectric refrigeration capable of heat recovery, which includes a thermoelectric refrigeration mechanism, a rotating mechanism, a thermoelectric power generation mechanism and an installation shell. It is installed on the rotating mechanism, and the cold medium conduction block is installed on the side of the installation shell. When the thermoelectric refrigeration unit rotates to communicate with the external pulse current on the cold medium conduction block, there will be transient supercooling on the basis of normal refrigeration, and then the thermoelectric The refrigeration unit will be accompanied by retaliatory thermal feedback, and the rotating mechanism will move the thermoelectric refrigeration unit that has retaliatory thermal feedback to the heat conduction medium block to connect with the electric power generation mechanism, and at the same time, the next group of thermoelectric refrigeration units will follow the external pulse on the cold medium conduction block The current connection continues the transient supercooling based on the normal cooling of the thermoelectric refrigeration unit, and such a cycle realizes the enhancement of the refrigeration capacity of the thermoelectric refrigeration, continuous high-efficiency refrigeration and the recovery and utilization of the heat generated by the thermoelectric refrigeration.

Description

technical field [0001] The invention relates to the technical field of thermoelectric refrigeration, in particular to a pulse thermoelectric refrigeration subcooling maintaining device 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 a medium, which will cause certain damage and impact on the environment; semiconductor refrigerators refer to the use of the thermo-electric effect of semiconductors. The device for taking cold energy, also known as thermoelectric refrigerator, has the characteristics of no noise, no vibration, no refrigerant, small size, light weight, etc., and it is reliable, easy to operate, and easy to adjust the cooling capacity. The principle is to connect two different metals with conductors and connect to direct current, the temperature at one junction will decrease, an...
