Example Embodiment

[0034] See figure 2 The magnetic refrigeration device 100 of an embodiment of the present invention mainly includes a magnetocaloric module 10 and a magnet unit 20 (such as a magnet or an electromagnet). The magnet unit 20 is arranged around the magnetocaloric module 10 and can reciprocate different magnetic fields. Pre-magnetic thermal module 10. Such as figure 2 As shown, the aforementioned magnetocaloric module 10 mainly includes a base 11, a first magnetocaloric material M1, a second magnetocaloric material M2, and a heat insulation structure 12, wherein the first and second magnetocaloric materials M1, M2 are provided In the base 11, the heat insulation structure 12 is located between the first and second magnetocaloric materials M1 and M2. In this embodiment, the gap between the first and second magnetocaloric materials M1 and M2 can be filled by the heat-insulating structure 12. In addition, a through hole or a porous structure can be formed inside the heat-insulating ...

Abstract

Disclosed are a magnetic refrigeration device and a magnetic heating module thereof. The magnetic refrigeration device comprises a magnetic heating module and a magnet unit. The magnet unit reciprocates to act on different magnetic fields for the magnetic heating module. The magnetic heating module comprises a base, first magnetic heating material, second magnetic heating material and a heat insulation structure. The first and second magnetic heating materials are disposed in the base. The heat insulation structure is disposed between the first and second magnetic heating materials. Heat transfer fluid flows through the first and second magnetic heating materials so as to transfer heat between low temperature and high temperature ends of the magnetic heating module. The multiple different magnetic heating materials are disposed in the magnetic heating module, the heat insulation structure is disposed between the different magnetic heating materials, and accordingly heat transfer between the different magnetic heating materials can be avoided effectively and the magnetic heating module is widely applicable to various magnetic refrigeration devices.

Description

technical field [0001] The invention relates to a magnetic refrigeration device, in particular to a magnetic refrigeration device with different magnetic-caloric materials and a magnetic-caloric module thereof. Background technique [0002] Since the magnetic cooling device does not need to use a specific refrigerant or compressor, it is not only simpler in structure than traditional refrigeration and air-conditioning equipment, but also does not generate noise pollution. On the other hand, the magnetic refrigeration device has the advantages of low energy consumption and low maintenance cost, so it has gradually become an important development project in the technical field of refrigeration and air conditioning. [0003] see figure 1 In 2006, International Journal of Refrigeration, Volume 29, pages 1327-1331, introduced a technology about active magnetic refrigeration (active magnetic regeneration, AMR). In the aforementioned literature, Gd 0.92 Y 0.08 、Gd 0.84 Dy 0.16...
