Abstract

The invention relates to a pulse tube refrigerating machine. The pulse tube refrigerating machine comprises a linear compressor, a main water cooler, a reheater, a cold-end heat exchanger, a pulse tube, a flow guide layer, an inertia tube cooling structure and a gas bin which are all sequentially connected. The inertia tube cooling structure comprises an inertia tube unit and a cooling unit. The cooling unit is used for cooling gas in the inertia tube unit. By the adoption of the pulse tube refrigerating machine, refrigerating efficiency is improved, an auxiliary water cooler in an existing pulse tube refrigerating machine can be omitted, the mechanism of the pulse tube refrigerating machine is simplified, and cost is reduced. The pulse tube refrigerating machine has the beneficial effects of being simple in structure, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the field of pulse tube refrigerators, in particular to a pulse tube refrigerator. Background technique [0002] The pulse tube refrigerator has no moving parts in the cold head, has the advantages of simple structure, stable operation, and reliable performance. It is a low-temperature refrigerator with great development potential. At present, Stirling-type pulse tube refrigerators have been successfully applied to many fields such as infrared detectors and superconducting filters. With the rise of strong electric superconducting technology, new requirements are put forward for the power of the pulse tube refrigerant: the refrigeration in the liquid nitrogen temperature zone must reach the kW level. High-power refrigerators need water coolers with high heat flux for cooling. [0003] figure 1 It is a schematic structural diagram of an existing pulse tube refrigerator, which consists of a linear compressor (not shown in the f...
