Problems solved by technology

Of the above three schemes, the first two need to switch the cold and hot water circulation according to the magnetic field position to complete the refrigeration or heating cycle, so a corresponding water distribution system needs to be designed and due to the limitation of the system response time, the refrigeration efficiency of the magnetic refrigeration system is low.
The third scheme has high cooling efficiency but the structure is complicated, and the use of water separator makes it more difficult to realize

Abstract

The invention relates to the technical field of refrigeration, in particular to a dynamic-seal dynamic closed-loop water channel circulating device for a magnetic refrigerator. The dynamic-seal dynamic closed-loop water channel circulating device comprises dynamic-seal slide slots and a rotary grid. The dynamic-seal slide slots are used for sealing refrigerants of the magnetic refrigerator, each slide slot is divided into the inner side and the outer side which are of multi-layer labyrinth rotary dynamic-seal structures, the inner side and the outer side of each slide slot are in dynamically slide seal, and water inlets and water outlets are attached onto the slide slots, so that a part of a dynamic water channel is formed. Besides, the rotary grid is used for holding magnetic working media, and the rotary grid and the dynamic-seal slide slots form a slide seal unit for forming the circulating water channel with the water inlets and the water outlets. The device can be used as a water cooling mechanism for the rotary magnetic refrigerator to complete heat exchange in a magnetic refrigeration process.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a dynamic sealing and dynamic closed-loop water circulation device for a magnetic refrigerator. Background technique [0002] Traditional magnetic refrigerators achieve the purpose of refrigeration through compressed gas expansion technology. Among them, Freon or hydrofluorocarbon is used as the compressed gas. Both gases are damaging to the atmosphere, can damage the atmospheric ozone layer or have a greenhouse effect. The magnetic refrigeration technology developed in recent years achieves the purpose of refrigeration through the change of magnetic entropy of materials in the process of magnetization and demagnetization. Because this material does not use gas refrigeration technology, it will not cause the greenhouse effect, so it is called green environmental protection refrigeration technology. In addition, compared with gas refrigeration systems, magnetic refrigerat...
