Abstract

The invention discloses a pulse tube refrigerator with an elastic air reservoir. The pulse tube refrigerator comprises a compressor, a transport tube, a water cooler, a heat regenerator, a cold end connecting pipe, a cold end heat exchanger, a pulse tube, a hot end heat exchanger, an inertance tube and an elastic air reservoir. The compressor is sequentially connected with the transport tube, thewater cooler, the heat regenerator, the cold end connecting pipe, the cold end heat exchanger, the pulse tube, the hot end heat exchanger, the inertance tube and the elastic air reservoir. A pulse tube refrigerator is usually provided with a huge air reservoir to obtain a better performance. The pulse tube refrigerator with the elastic air reservoir can obtain the same phase modulation effect with just a few percent of a common air reservoir in volume after employing the elastic air reservoir, so that the whole system becomes compact, and the charging quantity of working medium is reduced, which is particularly important for rare helium-4 and helium-3. As for the air reservoir in low temperature, the elastic air reservoir can shorten the cooling time and accelerate the cooling speed of a system.

Description

technical field [0001] The invention relates to a pulse tube refrigerator with an elastic gas store, which is suitable for pulse tube refrigerators of various applications such as small hole type, two-way air intake type, inertial tube type, or two-way air intake and inertial tube combined phase modulation type. tube refrigerator. Background technique [0002] The pulse tube refrigerator was jointly proposed by Gifford and Longthworth in the United States in the 1960s. The pulse tube refrigerator at that time was a basic pulse tube refrigerator, and the lowest temperature reached 124K in the experiment. This performance is far from that of Stirling and GM refrigerators. Therefore, the relevant research was interrupted for a while, and it was not until Mikulin in the former Soviet Union proposed the small hole type 20 years later that the pulse tube refrigerator entered a period of rapid development. In the 1990s, two-way inlet type, inertial tube type, four-valve type, do...
