Description

technical field

[0001] The invention relates to a two-way intake type pulse tube refrigerator with a bellows direct current blocking structure. Background technique

[0002] Because the low-temperature moving part-the ejector is removed, the pulse tube refrigerator avoids problems such as sliding seals and mechanical wear at low temperatures, and is expected to become a low-cost, low-vibration, stable and reliable long-life low-temperature refrigerator. Especially with the proposal and successful application of phase modulation structures such as small holes, gas banks, and two-way air intake, the cooling temperature of pulse tube refrigerators has been continuously reduced, and the cooling capacity and cooling efficiency have also been greatly improved, which is close to or even exceeded in some working conditions. Traditional regenerative cryogenic refrigerators (such as G-M refrigerators, Stirling refrigerators, etc.) have been practically used in the cooling of supercond...
