Abstract

A absorptive phase-regulating vessel refrigerating machine, belongs to vessel refrigerating machine comprising two-way intake valve, hot end vessel heat-exchanger, vessel, cold end vessel heat exchanger, cold head, cold-end heat exchanger of regenerator, regenerator, hot end heat exchanger of regenerator; its characteristics are a absorber connected with it is also set on the outer end of the said hot end vessel heat-exchanger, through the good capacitance and inductive resistance effect of absorber to replace the gas storeroom and inertia tube so as to achieve the best phase shift the refrigerating machine required in operation. Compared with the present vessel refrigerating machine installed with gas storeroom and inertia tube, the system has compact structure, good phase modulation capability, good stability and lower energy consumption, and will contribute to large-scale commercial application of vessel refrigerating machine.

Description

1. Technical field [0001] The invention relates to an adsorption phase modulation type pulse tube refrigerator, which belongs to the pulse tube refrigerator. 2. Background technology [0002] Because there are no moving parts at low temperatures, pulse tube refrigerators have outstanding advantages such as simple structure, low vibration, and high reliability. They are expected to be widely used in high-tech fields such as information, superconductivity, and space. According to the fluid theory of alternating fluid, in order to obtain good refrigeration performance of the pulse tube refrigerator, it is necessary to use various phase modulation mechanisms to make the pressure wave at the cold end in phase with the mass flow. After nearly 20 years of hard work by scholars from various countries, pulse tube refrigerators with various structures such as small hole gas storage type, two-way air inlet type and inertial tube type have been proposed successively. The performance of ...
