Abstract

The invention provides an ultra-miniature rotary integral Stirling cryocooler. The ultra-miniature rotary integral Stirling cryocooler comprises a base, a compression assembly, a pushing assembly, a rotor assembly and a stator assembly, the rotor assembly comprises a motor rotor and an eccentric rotating shaft, and an eccentric part of the eccentric rotating shaft extends into the base; and the compression assembly is in transmission connection with the eccentric rotating shaft through a compression connecting rod, one end of the pushing assembly is connected with the side face of the compression connecting rod, and the movement axes of the compression assembly and the pushing assembly are located on the same horizontal plane. According to the ultra-miniature rotary integral Stirling cryocooler, the compression assembly and the pushing assembly are connected with the eccentric rotating shaft through the compression connecting rod, the movement axes of the compression assembly and the pushing assembly are located on the same horizontal plane, the axial height of the cryocooler is effectively reduced, therefore, the size of the cryocooleris reduced, the problems that an existing integral Stirling cryocooler is tedious in structure, large in size and heavy in mass are solved, the movement direction of the compression assembly and the movement direction of the pushing assembly are located on the same horizontal plane, the bending moment load of the rotating shaft is reduced, and the system reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of Stirling refrigerators, and in particular relates to an ultraminiature rotary integrated Stirling refrigerator. Background technique [0002] With the continuous application of infrared technology in the fields of reconnaissance and warning, guidance and control, and long-range air defense at medium and high altitudes, infrared focal plane detectors continue to develop. As an important part of infrared detectors, refrigerators provide low-temperature working environments for chips. The integral Stirling refrigerator is one of the commonly used refrigerators in the field of infrared detection. With the diversification of application scenarios (such as: high temperature, field, etc.), infrared focal plane detectors continue to be light in weight, small in size, and low in power consumption. and development in the direction of high reliability. [0003] However, the existing integral Stirling refrigerators ...
