Problems solved by technology

[0005] Due to the relatively large thermal load of the Dewar and the high power consumption of the existing infrared detector components with large pixel specifications, they are mainly suitable for linear split Stirling refrigerators with relatively large cooling capacity.
However, the linear split Stirling refrigerator is large in size, heavy in weight, and high in power consumption, which will bring certain difficulties to the design of the whole machine system and limit some applications of infrared detector components.

Embodiment Construction

[0019] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] Generally speaking, for a rotary integrated Stirling refrigerator, as the cooling capacity increases, the piston stroke / piston diameter of the refrigerator will increase, so that the volume and weight of the refrigerator will also increase. The design technology of a miniaturized large cooling capacity rotary integrated Stirling refrigerator mainly includes: the thermodynamic design technology of the large cooling capacity re...

Abstract

The invention discloses a rotary integrated stirling cryocooler. The rotary integrated stirling cryocooler comprises a motor stator component and a cryocooler body connected with the motor stator component. The motor stator component comprises a first shell, a motor driving controller and a motor stator, and the motor driving controller and the motor stator are located in the first shell. The cryocooler body comprises a second shell, a motor rotor and a cooling component, and the motor rotor and the cooling component are located in the second shell. When the motor stator component is connected with the cryocooler body, the motor rotor in the cryocooler body is inserted into the motor stator, wherein the motor stator and the motor rotor constitute a motor. According to the rotary integrated stirling cryocooler, miniaturization and high cooling capacity of the cryocooler are realized by integrating the motor driving controller in the shell through combination of the optimum structural design. The rotary integrated stirling cryocooler has the characteristics of being compact in structure, small in size, light in weight, low in power consumption and the like.

Description

technical field [0001] The invention relates to the technical field of low-temperature refrigeration, in particular to a rotary integrated Stirling refrigerator. Background technique [0002] In recent years, with the wide application of infrared technology in military fields such as infrared imaging, reconnaissance and warning, early warning and surveillance, guidance, and long-range air defense at medium and high altitudes, infrared focal plane detector technology has developed rapidly. As an important part of the infrared detector Dewar cooling assembly (IDDCA assembly), the Stirling refrigerator is mainly used to cool the infrared detector, provide a low-temperature working environment for the infrared detector, reduce the noise of the infrared detector, and improve the performance of the infrared detector. Sensitivity and resolution, thereby improving the infrared imaging effect. [0003] The development of the Stirling refrigerator is closely related to the developmen...
