Description

technical field [0001] The invention relates to a fan, in particular to a magnetic refrigeration fan. Background technique [0002] The current refrigeration technology mainly relies on the compressor to compress the gas to cause the phase change of the working medium to refrigerate. The Carnot cycle efficiency is low, so its energy consumption is also large, and its structure is complex. Therefore, with the development of science and technology, magnetic refrigeration technology, as the future green refrigeration technology, is becoming a trend. The magnetocaloric effect is a property in which the internal magnetic entropy of the magnetic refrigeration material changes during the process of magnetization and demagnetization to release or absorb heat, and it is an inherent property of the material. Compared with traditional compressors, magnetic refrigeration can reach 30%-60% of the Carnot cycle, while the compressor refrigeration of general air conditioners can only reach...

Problems solved by technology

The magnetic refrigerators developed at this stage have various disadvantages. At present, the magnetic working medium in the magnetic refrigerator is mostly metal Gd block. In the process of cold and heat exchange, heat exchange is performed by controlling the fluid pipeline. Refrigeration requires the installation of a motion control system, complex structure, large volume, and high price. In the design of the magnetic field, it has the disadvantages of a small magnetic field in the working area or a large volume of the magnetic field module.
