Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0032] It should be noted that when it is called "fixed to" another, it can be directly on the other or there can be another middle, fixed through the middle. When one is considered to be "connected" to the other, it can be directly connected to the other or may exist in the other at the same time. When one is considered to be "set on" the other, it may be directly set on the other or may exist in the other at the same time. The terms "...

Abstract

The invention discloses a refrigerating machine. The refrigerating machine comprises a pressure shell, a machine body, a linear motor, a gas distributing piston and a power piston, the linear motor comprises an external stator, a magnet tank and an internal stator, the machine body and the external stator are fixedly mounted on the pressure shell, the internal stator is mounted on the machine body, the magnet tank is mounted on the power piston so as to enable the magnet tank to be in clearance fit with the external stator and the internal stator, the power piston is mounted in the machine body, the gas distributing piston is partially located in the power piston and is coaxial with the power piston, an expansion cavity is formed between the pressure shell and the gas distributing piston,and a compression cavity is formed between the gas distributing piston and the power piston. Through the design, the refrigerating machine is simple in structure, small in size and small in weight andis miniaturized.

Description

Technical field [0001] The present invention relates to refrigeration technology, in particular to a refrigerator. Background technique [0002] The working gas in the Stirling cycle refrigerator is helium or hydrogen which is sealed at high pressure and easily leaks. The working fluid (hydrogen or helium) in the cylinder is cooled, compressed, absorbed heat, and expanded into a cycle for refrigeration. [0003] However, the existing refrigerators are complex in structure, large in size and heavy in weight, and cannot be miniaturized, so that they can be applied to some occasions. Summary of the invention [0004] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a refrigerator with a simple structure, a small volume, a small weight and a miniaturization. [0005] A refrigerator includes a pressure shell, a body, a linear motor, a gas distribution piston, and a power piston. The linear motor includes an outer stator, a magnet ...
