Direct cooling magnetic refrigeration equipment

Abstract

The invention discloses a direct cooling type magnetic refrigeration device. The direct cooling type magnetic refrigeration device comprises a heat preservation box body and a magnetic refrigeration assembly; a heat conduction inner container is arranged in the heat preservation box body; and the magnetic refrigeration assembly comprises a magnetic field system. The direct cooling type magnetic refrigeration device is characterized is that the magnetic refrigeration assembly further comprises a heat pipe type magnetic refrigeration bed; the heat pipe type magnetic refrigeration bed comprises a heat pipe and magnetic working mediums; the heat pipe comprises a pipe body and liquid absorption cores arranged in the pipe body and comprises a condensation pipe section, a magnetic effect pipe section and an evaporation pipe section which are arranged in sequence; the magnetic effect pipe section is provided with the magnetic working mediums; valve assemblies capable of being opened and closed are arranged between the magnetic effect pipe section and the condensation pipe section and between the magnetic effect pipe section and the evaporation pipe section separately; the condensation pipe section is attached to the heat conduction inner container; and the evaporation pipe section is located outside the heat preservation box body. The direct cooling type magnetic refrigeration device has the advantage that the heat transfer efficiency can be improved so as to improve the refrigeration efficiency.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a direct cooling magnetic refrigeration equipment. Background technique [0002] At present, refrigeration equipment (such as refrigerators, freezers, and wine cabinets) is an electrical appliance commonly used in people's daily life. Refrigeration equipment usually has a refrigeration system. Generally, the refrigeration system is composed of a compressor, a condenser, and an evaporator, which can achieve a lower temperature. of refrigeration. However, with the development of magnetic refrigeration technology, refrigeration equipment using magnetic refrigeration modules for refrigeration is also widely used. The magnetic refrigeration module in the prior art usually includes a hot-end radiator, a cold-end radiator, a heat exchange fluid-driven pump, and a magnetic refrigeration assembly, and the magnetic refrigeration assembly includes a magnet and a magnetic refrigeration bed, and the...

Problems solved by technology

However, in the process of refrigeration using magnetic refrigeration technology, heat transfer is required through heat exchange fluid. Therefore, an additional solution circulation pump is required, which leads to complex piping structure of the refrigeration system, and the use of heat exchange fluid to transfer heat , will make the heat transfer efficiency lower
