Embodiment 1
[0027] Figure 4 It is a structural schematic diagram of Embodiment 1 of the low-temperature thermoacoustic refrigerator without inertia tube and gas store of the present invention, as Figure 4 As shown, the low-temperature thermoacoustic refrigerator without inertia tube and gas store of the present invention includes two refrigeration units composed of pressure wave generating device 1 and refrigerator components: the left refrigeration unit and the right refrigeration unit with the same structure unit; the refrigerator components of the left refrigeration unit and the right refrigeration unit include: regenerator hot-end heat exchanger 2, regenerator 3, cold-end heat exchanger 4, pulse tube 5, pulse tube hot-end heat exchanger device 6, small hole regulating valve 7 and two-way air intake regulating valve 8; said regenerator hot end heat exchanger 2, regenerator 3, cold end heat exchanger 4, pulse tube 5, pulse tube hot end heat exchange The device 6 and the small hole re...
Embodiment 2
[0031] Figure 5 It is a structural schematic diagram of embodiment 2 of the low-temperature thermoacoustic refrigerator without inertial tube and gas store of the present invention, as Figure 5 As shown, the main difference between it and Embodiment 1 is that: a bypass pipe is drawn between the regenerators of each refrigeration unit to connect to the pulse tube, and a bypass regulating valve 11 is set on the bypass pipe to adjust the heat from the regenerator. In this way, the phase adjustment capability of the small hole regulating valve 7 and the two-way inlet valve 8 can be increased to improve the efficiency of the low-temperature thermoacoustic refrigerator. The bypass is one or more.
[0032]Further, due to the loop formed by the two-way intake pipe where the two-way intake valve is located and the main gas circuit (or the loop formed by the bypass pipe between the regenerator and the pulse tube and the main gas circuit) may cause For circulation loss, a resistance ...
Embodiment 3
[0035] Image 6 It is a structural schematic diagram of Embodiment 3 of the low-temperature thermoacoustic refrigerator without inertia tube and gas store of the present invention, as Image 6 As shown, the main difference between it and Embodiment 1 is that the regenerators 3 of the left and right refrigeration units are composed of two cascaded upper sub-regenerators and lower sub-regenerators, (of course, the sub-regenerators The number is not limited to two, and more sub-regenerators can be set in series), and the sub-regenerators with multi-stage structure can achieve lower cooling temperatures, and can also obtain cooling capacity at different temperatures at the same time; Embodiment The joints of the upper and lower sub-regenerators of the two regenerators 3 are respectively connected to the second cold-end heat exchanger 4', the second pulse tube 5', and the second pulse tube hot-end heat exchanger through pipelines. 6' and the second small hole regulating valve 7', ...
