Abstract

The invention relates to a split-stirling cryocooler air inflation and performance test bed, comprising a vacuumizing device used for vacuumizing a cryocooler, a helium gas injection device used for injecting a helium gas into the cryocooler, a helium mass spectrometer leak detector used for detecting leak of the cryocooler and a test system used for testing cooling performance of the cryocooler,wherein the cryocooler, the vacuumizing device, the helium gas injection device and the helium mass spectrometer leak detector are connected with the test system. The test bed provided by the invention solves many problems appearing in a manual operation process and is integrated with later data processing and report generation. The test bed provided by the invention is high in automation degree and high in reliability and can achieve unattended operation, so that research and development time is greatly shortened and product engineering application level is improved, and the test bed is innovative, is a leading technology in China, has a wide use space and can produe relatively high economic benefit.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a test bench for charging and performance testing of a separate Stirling refrigerator. Background technique [0002] With the development of photoelectric technology, infrared detectors are more and more widely used in military reconnaissance, thermal imaging, early warning, remote sensing and meteorology. The sensitivity of the infrared detector is greatly affected by temperature, so it is necessary to cool down the infrared detector to improve the sensitivity. Due to its small size, compact structure and low vibration, the Stirling refrigerator is especially suitable for providing refrigeration for the infrared detector. Therefore, the cooling performance of the Stirling refrigerator has a great relationship with the sensitivity of the infrared detector. The detection of the refrigeration performance of the Stirling refrigerator is also particularly important. [0003] ...
