A magnetic refrigeration heat exchange system

Abstract

The invention relates to a magnetic refrigeration heat exchange system. The magnetic refrigeration heat exchange system comprises a heat end heat exchange part, a magnetic heat exchange part and a cold end heat exchange part communicating in sequence by pipelines, and a power module communicating with the heat end heat exchange part and used for driving a fluid in the magnetic refrigeration heat exchange system; and a refrigerating part is arranged between the cold end heat exchange part and the magnetic heat exchange part. The refrigerating part is arranged between the cold end heat exchangepart and the magnetic heat exchange part; and after the demagnetization cooling is performed on the fluid flowing out from the magnetic heat exchange part, the temperature of the fluid is further lowered through secondary cooling by the refrigerating part, so that the temperature difference of the fluid with the cold end heat exchange part after the fluid enters the cold end heat exchange part ishigher, the refrigerating quantity is sufficient, and the refrigerating effect is obviously improved.

Description

technical field [0001] The invention relates to the technical field of magnetic refrigeration, in particular to a magnetic refrigeration heat exchange system. Background technique [0002] Magnetic refrigeration technology is a technology that applies the magnetocaloric effect of magnetic materials to the field of refrigeration. The magnetocaloric effect is an inherent property of magnetic materials. It is the change of the magnetic entropy of the material itself caused by the change of the external magnetic field. Endothermic and exothermic process. For example, for ferromagnetic materials, the magnetocaloric effect is most significant near its Curie temperature. When an external magnetic field acts, the magnetic entropy of the material decreases and heat is released; conversely, when the external magnetic field is removed, the magnetic entropy of the material The value rises and absorbs heat, which is similar to the exothermic-endothermic phenomenon caused by the compress...

Problems solved by technology

However, in the existing magnetic refrigeration system, the temperature of the fluid cooled by demagnetization is still high, and the temperature difference between the cold-end heat exchanger and the cold-end heat exchanger after entering the cold-end heat exchanger is small, the cooling capacity is insufficient, and the cooling effect is not good.
