Magnetic refrigeration system and magnetic refrigeration device

Abstract

The invention provides a magnetic refrigeration system and a magnetic refrigeration device. The magnetic refrigeration system comprises a cold accumulation bed (1), a magnet (2) and a cold accumulation bed mounting disc (4), wherein the cold accumulation bed (1) is arranged on the cold accumulation bed mounting disc (4), the cold accumulation bed (1) and the cold accumulation bed mounting disc (4)can be integrally rotated, so that the relative movement between the cold accumulation bed (1) and the magnet (2) can be generated and a process of magnetizing or demagnetizing can be performed; andthe system further comprises a rotating shaft (5), the rotating shaft (5) is connected with the cold accumulation bed mounting disc (4) and can also be integrally rotated with the cold accumulation bed mounting disc (4), a flow path for a heat exchange fluid to flow is arranged on the rotating shaft (5), and the heat exchange fluid can enter the cold accumulation bed (1) from the outside through the flow path and can also flow out from the cold accumulation bed (1) to the outside through the flow path. According to the device, the existing technical problems of large energy consumption and lowmechanical efficiency can be solved, and the existing problems of pipeline winding and complex structure caused by the rotation of the cold accumulation bed can also be solved.

Description

technical field [0001] The invention belongs to the technical field of magnetic refrigeration, and in particular relates to a magnetic refrigeration system and a magnetic refrigeration device. Background technique [0002] Magnetic refrigeration technology is a new type of refrigeration technology based on the magnetocaloric effect, which refers to the physical phenomenon that magnetocaloric materials release or absorb heat when the magnetic field increases or decreases. When the magnetic field magnetizes the magnetocaloric material, the magnetic entropy of the magnetocaloric material becomes low and releases heat; when the magnetic field is removed, the magnetic entropy of the magnetocaloric material becomes high and absorbs heat. Magnetic refrigeration is to use the phenomenon of magnetocaloric effect to achieve the purpose of refrigeration. [0003] According to the development of the magnetic refrigerator, it can be divided into static type, reciprocating type and rotar...
