Transmission mechanism for magnetic refrigerator

Abstract

The transmission mechanism for the magnetic refrigerator comprises a refrigeration pipe and a refrigeration block sliding in the refrigeration pipe, the side wall of the first side of the refrigeration pipe is fixedly connected with a driving box, the side wall of the refrigeration block is fixedly connected with a driving rod, and the tail end of the driving rod penetrates through the driving box and extends into the driving box. And a driving mechanism capable of controlling the driving rod to reciprocate is arranged in the driving box. The reciprocating motion of the refrigeration block can be effectively controlled, and meanwhile the heat exchange process can be achieved.

Description

technical field [0001] The invention relates to the technical field of magnetic refrigerators, in particular to a transmission mechanism for magnetic refrigerators. Background technique [0002] Magnetic refrigerator is a new type of refrigeration equipment using magnetocaloric effect. Compared with traditional compression refrigeration technology, it has the advantages of low noise and low vibration. It achieves the purpose of refrigeration by controlling the repeated magnetization and demagnetization of magnetic materials. The refrigeration process does not require the participation of freon and other substances, and it is a new type of environmentally friendly refrigeration equipment. [0003] Patent document CN104329422B discloses a transmission mechanism, which uses a screw to drive the slider on the guide rail to move, and then realizes the control of the magnetic working fluid packaging box entering and exiting the magnetic field to achieve the purpose of cooling, but...

Problems solved by technology

[0003] Patent document CN104329422B discloses a transmission mechanism, which uses a lead screw to drive the slider on the guide rail to move, and then realizes the control of the magnetic working fluid packaging box entering and exiting the magnetic field to achieve the purpose of cooling, but the above-mentioned transmission mode occupies a large volume, It is only suitable for large-scale magnetic refrigerators, and cannot be applied to lightweight and small refrigerators, and the water pump installed inside the small magnetic refrigerator is noisy, and the water flow cannot be accurately controlled, which affects the use of the equipment. In view of the above situation, so There is a need for a transmission mechanism for a magnetic refrigerator
