Solid-state refrigeration device and method based on Lalka effect

Abstract

The invention provides a solid-state refrigeration device and method based on a Lalka effect. The solid-state refrigeration device comprises an internal accessory and an external accessory, the internal accessory comprises a shell, a cover plate, a solid-state refrigerant, a deformation driving mechanism and a transportation medium, an inner groove is formed in the center of the shell, the cover plate and the shell are connected in a sealed configuration mode to form an inner concave cavity, the deformation driving mechanism is arranged in the center of the inner concave cavity, an annular medium cavity is formed, the transportation medium is stored at the bottom in the medium cavity, one end of the solid-state refrigerant is fixed to the shell, the other end of the solid-state refrigerant is fixed to the deformation driving mechanism, and heat and cold energy generated by the solid-state refrigerant are conveyed to the external accessory through the transportation medium. Heat and cold energy generated by reversible conformation change or reversible phase change of the solid-state refrigerant material are utilized, and the effect of separating and transmitting the cold energy and the heat is achieved through flowing of the transportation medium.

Description

technical field [0001] The invention belongs to the technical field of solid-state refrigeration, and in particular relates to a solid-state refrigeration device and method based on the Racha effect. Background technique [0002] Refrigeration through the compression or expansion of gas is the main working method of modern refrigeration equipment. During its long-term application, it was found that there are two obvious disadvantages: the refrigeration efficiency of the compressor is low, and the refrigerant represented by Freon is the culprit of air pollution. As people's requirements for energy saving and environmental protection are getting higher and higher, it is particularly urgent to find new refrigeration methods to replace traditional gas compression refrigeration. In this social background, solid-state refrigeration technology came into being. [0003] The working basis of this new refrigeration technology is the reversible thermal effect of solid-state materials...

Problems solved by technology

Although the lower stress requirement improves the feasibility of the research and development of this type of Larca effect material refrigeration device, the larger strain also increases the external size of the refrigeration device, and is not conducive to the separation and export of Larca effect heat
