Description

1. Technical field [0001] The invention relates to a cold feedback system of magnetic liquid magnetic refrigeration. 2. Background technology [0002] At present, there are three main refrigeration technologies: Freon refrigeration, semiconductor refrigeration and magnetic refrigeration. Freon refrigeration is widely used, but it has the defects of damage to the atmosphere, pollution and high energy consumption; semiconductor refrigeration technology is relatively mature, but due to its low refrigeration efficiency, it can only be used in some small-scale refrigeration Occasions: Magnetic refrigeration technology is a rapidly developing refrigeration technology at present, mainly including magnetic refrigeration technology using solid magnetic refrigeration materials and magnetic refrigeration technology using liquid magnetic refrigeration materials. It is impossible for solid magnetic refrigeration materials to exchange heat through piping like liquid or gas heat exchange,...
