Magnetic fluid refrigerating refrigerator

Abstract

The invention provides a magnetic fluid refrigerating refrigerator, and belongs to household appliances; the refrigerator comprises a shell, a metal circulating pipeline section is arranged on the shell, a part of the circulating pipeline is arranged at the interior of the shell, the other part of the circulating pipeline is arranged on the exterior of the shell, and the external part of the shell is composed of an iron pipe; the internal part of the shell is composed of a copper pipe or an aluminum pipe, the circulating pipeline is filled with a magnetic fluid, and the circulating pipeline is connected with a circulating pump in series; and the circulating pipeline arranged on the exterior of the shell is tightly attached to a permanent magnet along the circulating pipeline. The refrigerator abandons a compressor refrigeration system of a traditional refrigerator and adopts a magnetic refrigeration system; compared with a refrigerating ring type magnetic refrigeration system, the refrigerator provided by the invention has the advantages of small volume, good magnetization effect, and good refrigerating efficient.

Description

Technical field [0001] The present invention relates to a household electrical appliance, in particular to a refrigeration refrigerator, which includes a refrigerator casing. Background technique [0002] Refrigerator is a basic household electrical equipment used to store food. Its refrigeration system mainly includes compressor, evaporator, condenser, throttle valve and circulation pipeline. The evaporator is located in the refrigerator body and is mainly composed of copper tubes. Installed outside the refrigerator, with a fan, the compressor compresses the working medium to liquefy it in the condenser to release heat, and circulates the liquid working medium to the throttle valve and evaporator to evaporate and absorb heat in the evaporator. Thereby reducing the temperature in the refrigerator. [0003] For the above-mentioned traditional refrigerator, since the compressor is required to work, it has relatively large noise. In addition, there are many mechanical parts in...

AI Technical Summary

Problems solved by technology

In the current magnetic refrigeration refrigerator, the cooling effect is obtained mainly through a circular ring composed of paramagnets, which rotates continuously inside and outside the refrigerator. For this kind of refrigeration ring structure, a large layout space is required, which increases the capacity of the refrigerator. In addition, because the refrigeration ring needs to rotate, the magnetized body cannot be close to the refrigeration ring, and the air gap between them will cause a large magnetic leakage, which is not conducive to the magnetization of the refrigeration ring and affects the refrigeration efficiency
