Gas gap phase modulation cryogenic refrigerator technology

It combines the advantages of GM cryogenic refrigerator and pulse tube cryocooler. The effect of the gas between the cylinder and the piston in the GM cryogenic refrigerator is achieved through the function of the phase modulation device to achieve the effect of the pulse tube refrigeration, and the sealing ring is cancelled, thus the problem of the cooling performance and the decrease of the reliability caused by the wear of the seal ring is solved, and the maintenance period and life of the cold head are greatly extended. A global patent and a domestic patent have been applied.
Oil separation technology of nanofiltration channel

Through the use of nano scale advanced filter materials and oil separation technology, the oil in the high-pressure helium produced by the pressure package is completely separated and returned to the pressure package, which reduces the burden of the oil absorber and greatly prolongs the maintenance cycle of the compressor.
Pulse tube refrigerator technology for automatically adjusting gas flow and phase

According to the performance attenuation signal caused by the changing conditions of the refrigerator, the flow and phase of the gas in the system are automatically adjusted, thus reducing the attenuation of the refrigeration performance and greatly improving the reliability and stability of the refrigerator.
Environmental protection and energy saving cryogenic vacuum pump technology for large scale integrated circuit

The air volume distribution of frequency conversion and compressor can be adjusted to achieve the effect of energy saving; environmental protection type cold storage materials are adopted, intelligent control, rapid regeneration and complete regeneration, and improved structure and size design of cold plate, large pumping speed and pumping capacity; gas clearance phase modulation cryogenic refrigeration technology and nanometer filter pass. The oil separation technology has greatly extended the maintenance cycle and service life of cryogenic vacuum pumps
