Embodiment Construction

[0077] Such as Figure 1-11 As shown, the present invention provides a magnetic refrigeration device, which includes:

[0078] A magnet assembly 1 capable of generating an alternating magnetic field;

[0079] The cold storage bed assembly 2 can accommodate the magnetic working medium, so that the magnetic working medium can generate excitation heat release or demagnetization heat absorption through the alternating magnetic field;

[0080] The cold-end heat exchanger 3 is capable of releasing the cold energy in the cold-end heat exchanger 3 through the heat exchange fluid that is absorbed and cooled by the magnetic working fluid in the cold storage bed assembly;

[0081] The hot-end heat exchanger 4 is capable of releasing heat in the hot-end heat exchanger 4 through the heat exchange fluid heated by the magnetic working fluid in the cold storage bed assembly;

[0082] It also includes a cold end rotary valve 5, the cold end rotary valve 5 is arranged between the cold storage...

Abstract

The invention provides a magnetic cooling device. The magnetic cooling device comprises a cold-end rotary valve which is arranged between a cold accumulation bed component and a cold-end heat exchanger; and a heat exchanging fluid between the cold accumulation bed component and the cold-end heat exchanger is enabled to be switched between communication and closing communication through rotation ofthe cold-end rotary valve; and / or, the magnetic cooling device further comprises a hot-end rotary valve which is arranged between the cold accumulation bed component and the hot-end heat exchanger; and besides, the hot-end rotary valve can rotate to enable the heat exchanging fluid to be switched between communication and closing communication. By adopting the magnetic cooling device, the situation in a magnetic cooling device in the prior art that a great number of pipelines need to be connected between the cold accumulation bed component and the cold-end heat exchanger as well as between the cold accumulation bed component and the hot-end heat exchanger to realize communication and closing communication of the fluid path is omitted; and the problems of large size and uncompact structureof the magnetic cooling mechanism are solved.

Description

technical field [0001] The invention belongs to the technical field of magnetic refrigeration, and in particular relates to a magnetic refrigeration device. Background technique [0002] The invention relates to the field of magnetic refrigeration, and mainly relates to the structure and flow path system of a rotary magnetic refrigeration device. [0003] As the disadvantages of traditional vapor compression refrigeration technology in terms of environmental unfriendliness and heat transfer efficiency are becoming more and more obvious, the research and development of new refrigeration technology (non-vapor compression refrigeration) is becoming more and more urgent. Magnetic refrigeration technology is one of the new refrigeration technologies with the most promising development prospects, especially its advantages in environmental friendliness and high efficiency. Compared with traditional vapor compression refrigeration, the refrigeration efficiency of magnetic refrigerat...
