A low-power magnetic refrigerator without external heat source interference

Abstract

The invention discloses an outer heat source interference-free low power consumption magnetic refrigerator which comprises a rack, a rotary disc, magnetic refrigerants, permanent magnets, a driving wheel, a driving module and a circulating cooling module, wherein the rotary disc is rotatably fixed on the rack; the flake-like magnetic refrigerants are distributed on the front and reverse sides of the rotary disc in an annular array; the permanent magnets are symmetrically distributed at the upper part of the rotary disc; the driving wheel is rotatably fixed on the rack; the side surface of the driving wheel and the side surface of the rotary disc are tangent and the rotary disc is driven by the driving wheel through friction force; and the circulating cooling module comprises a cooling water tank, a plurality of sections of cooling water pipes positioned at the two ends of cooling water tank, and a piezo-stack pump connected on one cooling water pipe. According to the outer heat source interference-free low power consumption magnetic refrigerator, a heat source is eliminated for the integral refrigerator device, so that the heat source is prevented from interfering the environment, the refrigerating efficiency is improved, and the energy consumption is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of refrigerators, in particular to the technical field of magnetic refrigerators. 【Background technique】 [0002] The well-applied traditional refrigeration technology mainly relies on the compression and expansion of the gas to change the phase of the working medium. On the one hand, it produces substances that cause the destruction of the atmospheric ozone layer. On the other hand, this process of gas compression and expansion requires gas compressors and other equipment. Combining structures and complex equipment can be realized. With the development of science and technology and the urgent requirements of environmental protection, refrigeration technology has been developing in the direction of no environmental damage. Magnetic refrigeration technology has developed strongly under the impetus of the above requirements new refrigeration technology. [0003] Magnetic refrigeration technology is a techno...
