Solid-state refrigeration device

Abstract

The invention relates to the technical field of solid-state refrigeration, and discloses a solid-state refrigeration device which comprises a magnet, a first heat exchanger, a second heat exchanger, a valve body, a mounting shell with a cavity, a first magnetostrictor, a second magnetostrictor and a solid-state refrigeration working medium. The solid refrigeration working medium is clamped between the first magnetostriction body and the second magnetostriction body; a through hole communicated with the cavity is formed in the mounting shell; the multiple installation shells are sequentially arranged in the circumferential direction of the first axis and define a channel communicating with the through hole. And when the multiple mounting shells rotate relative to the first axis, the first magnetostriction body and the second magnetostriction body passing through the magnetic field of the magnet move in opposite directions, so that the corresponding solid-state refrigeration working media are compressed to release heat. According to the solid-state refrigeration device, due to the fact that the multiple mounting shells rotate around the first axis, the influence of inertia force on the solid-state refrigeration device is small, and work of the solid-state refrigeration device is more stable.

Description

technical field [0001] The invention relates to the technical field of solid-state refrigeration, in particular to a solid-state refrigeration device. Background technique [0002] At present, air conditioners and refrigerators are mainly refrigerated by mechanical evaporation-condensation cycle, in which Freon is a gas that causes the greenhouse effect. Therefore, it is necessary to seek a new refrigeration technology that is relatively cheap and does not cause the greenhouse effect. With the continuous in-depth research of scientists, solid-state refrigeration technology is considered to be a new type of refrigeration technology with great potential and can replace Freon. [0003] Solid-state refrigeration technology has attracted more and more attention because of its higher refrigeration efficiency and more environmentally friendly advantages. However, the current refrigeration devices using solid-state refrigeration technology are too large in size and need to continuo...

[0003] Solid-state refrigeration technology has attracted more and more attention because of its higher refrigeration efficiency and more environmentally friendly advantages. However, the current refrigeration devices using solid-state refrigeration technology are too large in size and need to continuously use the reciprocating motion of solid-state refrigerants. Each reciprocating movement requires a start and stop, resulting in the current solid-state refrigeration device being too bulky and complex in structure
