Description

technical field [0001] The invention relates to a magnetic refrigeration technology, in particular to a high-efficiency heat dissipation system for a magnetic refrigerator and a heat dissipation method thereof. Background technique [0002] Heat dissipation technology is an important aspect of improving the performance of magnetic refrigeration. Good heat dissipation performance can reduce the temperature of the heat exchange fluid entering the refrigeration bed, improve the performance of the refrigerator, and broaden the temperature span of the refrigerator. [0003] At present, the heat dissipation system of magnetic refrigerators is basically air-cooled, that is, the fan is installed on the radiator. The heat exchanging fluid flowing out from the hot end flows into the radiator, where it dissipates heat under the action of the fan. This heat dissipation method is relatively simple, but there is a big problem. When the refrigerator runs for a period of time, the water te...

Problems solved by technology

This heat dissipation method is relatively simple, but there is a big problem. When the refrigerator runs for a period of time, the water temperature gradually rises, and it is difficult to reduce the water temperature by simple air-cooled heat dissipation, resulting in a significantly higher temperature of the water entering the refrigeration bed, even higher than The Curie temperature of the magnetic working medium material is extremely unfavorable to the refrigeration of the refrigerator. A part of the cooling capacity of the demagnetization refrigeration of the refrigerator is neutralized, which makes it difficult to expand the temperature span of the refrigerator, and the cooling capacity drops significantly. Even the temperature of the cold end and the cold room There is a possibility of a slight rebound
