Problems solved by technology

However, due to the connection between the motor design and the refrigerator, the processing and manufacturing process requires high processing precision for motors, leaf springs and other components, so the cost is high
In addition, the thermodynamic and dynamic characteristics of the refrigerator interact and restrict each other. The motion phase and stroke will change due to changes in the internal and external environments of the refrigerator, and there are also mutual influences and constraints. The cooling capacity and temperature control are more complicated, which affects refrigeration Machine working reliability

Abstract

The Stirling refrigerator with linear slide rail bearing support consists of mainly compressor, cold head in 90 deg to the compressor, drive motor, and crank connecting mechanism. It features that there are linear slide rail bearing installed between the piston and the cylinder body and linear slide rail bearing installed between the exhauster and the cold cylinder. Supporting the piston and the exhauster separately with linear slide rail bearing can ensure the radial positions of the piston and the exhauster during the axial reciprocation, reduce or eliminate friction to cylinder, raise the reliability of the refrigerator and prolong the service life of the refrigerator.

Description

technical field [0001] The invention belongs to a refrigerator in the technical field of refrigeration, in particular to a Stirling refrigerator supported by a linear sliding rail bearing. Background technique [0002] The Stirling refrigerator is an active refrigerator, and its refrigeration cycle is a Stirling reverse cycle (a thermodynamic cycle consisting of two isothermal processes and two isothermal reheat processes). Stirling refrigeration has the advantages of high cooling efficiency, small size, light weight, fast start-up, flexible installation, wide working temperature range, easy operation, etc. It is widely used in infrared detectors, X-ray meters, gamma ray measuring instruments, high temperature CMOS circuits in superconducting filters and computers, cold traps for trapping water vapor, etc. [0003] Since the first Stirling refrigerator came out in 1954, countries have conducted in-depth research on Stirling refrigerators. Due to the development of infrared...
