Problems solved by technology

This type of structure and design increases the heat dissipation area to a certain extent, and the heat dissipation efficiency is also improved to a certain extent, but there are still shortcomings: the design of this type of heat dissipation structure is based on the heat dissipation under the existing room temperature conditions, that is to say , the heat dissipation threshold of this type of structural scheme cannot be lower than room temperature, the heat dissipation efficiency is low, and once the heat dissipation structure and heat dissipation method are determined, the heat dissipation efficiency of the system, the structural size of the installation, etc. will also be determined, the heat dissipation is constant, and the environmental adaptability is poor

Abstract

The invention discloses a magnetic refrigeration cooling device and control system which comprises a magnetic refrigeration system, a cooling system and a driving control system. The magnetic refrigeration system comprises a magnetic field system, a magnetic working medium device, a refrigeration end and a heating end, a magnetic working medium is placed into the magnetic field system, the magnetic torque of the magnetic working medium is neat or disordered along with change of a magnetic field direction, the cooling system comprises a pump, a disk seamless cooling pipeline, a disk seamless heat absorption pipeline, a draft tube and cooling liquid, and the cooling liquid circulates in the pipeline in a reciprocating manner under driving of the pump. By the aid of a single-chip microcomputer in the adaptive on-off driving control system for an intelligent temperature control switch, on one hand, periodic change of the magnetic field system is controlled, on the other hand, the pump is controlled to drive the cooling liquid to periodically and circularly flow, the cooling efficiency of the system is higher than that of a traditional single cooling system by the aid of magnetic refrigeration technology, magnetic leakage can be effectively decreased, a cooled part can be intelligently cooled, energy is saved, environments are protected, pollution is avoided, and noise is quite low.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a magnetic refrigeration heat dissipation device and a control system. Background technique [0002] Magnetic refrigeration refers to a new type of refrigeration technology that uses magnetic materials as working fluids. During the demagnetization process, due to the change of internal magnetic entropy, the material absorbs and releases heat, that is, when the magnetic field applied to the magnetic material increases, its temperature rises; when the magnetic field applied to the magnetic material decreases, its temperature decreases, and it It is an inherent characteristic of magnetic materials and a new technology with energy saving, environmental protection, low vibration and noise, and high reliability. [0003] With the rapid development of electronics and semiconductor technology, electronic devices and semiconductor integrated circuits are developing in the direct...
