Pulse tube refrigeration early than at the beginning of 1964 by American scholar W.E.Gifford and R.C.Longsworth at Trans.ASME, propose in " Pulse Tube Refrigeration " literary composition of the 86th phase of J.Eng..They alternately pressurize and reduce pressure the elongated tubular of one one end sealing, and heat just is transferred to the other end by an end of pipe, sets up considerable thermograde in pipe vertically, and this refrigeration modes is called pulse tube refrigeration.E.I.Mikulin etc. 1984 have introduced in the 29th volume " LowTemperature Expansion Pulse Tubes " literary composition of Advances in Cryogenic Engineering and have added aperture in the pulse tube hot junction and air reservoir improves, nineteen ninety S.Zhu etc. have introduced the bidirection air intake improvement project in Cryogenics the 30th volume " Double inlet pulse tuberefrigerators:an important improvement " literary composition, make single-stage pulse tube refrigerating machine minimum temperature can reach 20-30K.Pulse tube refrigeration has at low temperatures distinct advantages such as movement-less part, phase modulation means are various, property regulation wide ranges, but pulse tube refrigeration efficient is lower, the through engineering approaches exploitation relatively lags behind.
Summary of the invention:
Be deficiency and the defective that overcomes prior art, the invention provides a kind of new solutions for refrigeration---split-type gas driven stirling-pulse tube coupled refrigerator, split-type gas driven stirling circularly cooling machine and pulse tube refrigerating machine are coupled to form.The split-type gas driven stirling refrigerating part is freezed according to the operation principle of split-type gas driven stirling refrigeration; The pulse tube refrigeration part is freezed according to the principle of pulse tube refrigeration.Split-type gas driven stirling refrigerating part and pulse tube refrigeration part provide pressure oscillation gas by same compressor, both have same displacer/regenerator, pneumatic cavity/air reservoir is a pneumatic cavity for the effect of split-type gas driven stirling refrigerating part, and effect partly is an air reservoir for pulse tube refrigeration.The cold chamber of split-type gas driven stirling refrigerating part is connected by the cool end heat exchanger of a tubule with the pulse tube refrigeration part, the hot end heat exchanger of pulse tube refrigeration part links to each other with the hot chamber of split-type gas driven stirling refrigerating part by the bidirection air intake valve, and hot end heat exchanger also links to each other with pneumatic cavity/air reservoir by little ports valve.
The split-type gas driven stirling-pulse tube coupled refrigerator that the present invention provides combines the advantage of split-type gas driven stirling refrigeration machine and two kinds of refrigeration machines of pulse tube refrigerating machine, make the two replenish mutually, the multiple control phase means of while pulse tube refrigeration, the adjustable range that obtains high serviceability is further enlarged, and can compensate the weakness of split-type gas driven stirling refrigerating part performance degradation automatically, make refrigeration machine refrigeration better effects if, index of aging that further raising be arranged.
Description of drawings and specific embodiment Fig. 1 split-type gas driven stirling-pulse tube coupled refrigerator structural principle schematic diagram;
As shown in Figure 1, the present invention is coupled to form by split-type gas driven stirling circularly cooling part I and pulse tube refrigeration part II, mainly comprises compressor 2, cooler 3, connection flexible pipe 4, hot chamber 5, drive rod 6, displacer/regenerator 7, cold chamber 8, connects tubule 9, cool end heat exchanger 10, bidirection air intake valve 11, pulse tube 12, hot end heat exchanger 13, aperture valve 14, pneumatic cavity/air reservoir 15 etc.Split-type gas driven stirling circularly cooling part I and pulse tube refrigeration part II provide pressure oscillation gas by same compressor 2, and both have common displacer/regenerator 7.Pneumatic cavity/air reservoir 15 is a pneumatic cavity for the effect of split-type gas driven stirling refrigerating part I, is air reservoir for the effect of pulse tube refrigeration part II.Pulse tube 12 is elongated thin-wall stainless steel, and its two ends are respectively cool end heat exchanger 10 and hot end heat exchanger 13.Cold chamber 8 connects tubule 9 by one and is connected with cool end heat exchanger 10, hot end heat exchanger 13 by bidirection air intake valve 11 be connected flexible pipe 4 one ends and be connected, connection flexible pipe 4 other ends are connected with hot chamber 5.Cooler 3 behind the compressor 2 is connected with hot chamber 5 by connecting flexible pipe 4, installation one aperture valve 14 on hot end heat exchanger 13 and pipeline that pneumatic cavity/air reservoir 15 is connected.
Know that by Gas Refrigerator General Theory cold computing formula Q=∫ pdV (Q is a cold, and p is cold cavity pressure, and V is a cold chamber volume) necessary condition that produces cold is: 1. cold cavity pressure fluctuation; 2. cold chamber volume fluctuations; 3. cold cavity pressure fluctuation keeps rational phase difference with volume fluctuations.
