Abstract

The invention discloses a semiconductor refrigerating module provided with solid-state fans. The semiconductor refrigerating module comprises semiconductor refrigerating pieces and heat dissipation assemblies. The hot end faces and the cold end faces of the semiconductor refrigerating pieces are provided with the heat dissipation assemblies respectively. At least one heat dissipation assembly is provided with the solid-state fan. The invention further discloses a refrigerating container comprising the semiconductor refrigerating module. According to the semiconductor refrigerating module provided with the solid-state fans and the refrigerating container comprising the semiconductor refrigerating module, the solid-state fans are based on the corona discharge principle, mechanical movement components are omitted, and vibration and noise caused by a mechanical fan are avoided; meanwhile, the solid-state fans are low in working current and low in power consumption, heat dissipation fin plates can be utilized directly to serve as collector electrodes, and therefore the overall size and weight of a heat dissipation system are greatly reduced; in addition, the air speed can be changed by changing the voltage applied to discharge electrodes, the distance between the discharge electrodes and an electrode plate, and the distance between the discharge electrodes. The semiconductor refrigerating module provided with the solid-state fans and the refrigerating container comprising the semiconductor refrigerating module have the advantages that the structure is more compact and lighter, the operation process is free of vibration and noise, the efficiency is higher, the air speed is easy to control, and design and optimization can be conducted with higher degree of freedom according to requirements.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a semiconductor refrigeration module with a solid-state fan and a refrigerator including the module. Background technique [0002] In order to reduce the vibration and noise caused by mechanical pumps, valves and other structures in the refrigeration process, more and more researches have been carried out on refrigeration devices without valves and mechanical pumps. Ammonia diffusion absorption refrigerator is a ternary working fluid absorption refrigerator, which uses liquid evaporation to achieve continuous refrigeration. The ammonia water diffusion absorption refrigerator uses ammonia as the refrigerant, water as the absorbent, and auxiliary inert gas as the diffusing agent. Function, so that the whole system does not need to be equipped with valves, and at the same time, the principle of thermosiphon is used to enable the refrigeration system to run in a cycle, without...
