Adsorption compressor based on semiconductor refrigeration and its driven cryogenic refrigerator

Abstract

The invention provides an adsorption type compressor based on semiconductor refrigeration and low-temperature refrigerating machine driven by adsorption type compressor. The adsorption type compressorcomprises a compressor cavity arranged in a shell, wherein a physical adsorption material is filled in the cavity and is provided with a heating wire, the tail end of the cavity is in communication with one end of a gas pipeline penetrating through the shell through a filter, the part of the gas pipeline protruding out of the shell is wrapped by a rear cooler, and a heat insulation layer is arranged between the inner side of the shell and the outer side of the compressor cavity; and a semiconductor refrigerator used for cooling the physical adsorption material is wrapped on the outer side ofthe shell. The low-temperature throttling refrigerating machine comprises the adsorption type compressor, wherein the tail end of the gas pipeline of the compressor is connected with an evaporator through a high-pressure side pipeline and a low-pressure side pipeline which are connected in parallel, and buffer tanks are arranged on the high-pressure side pipeline and the low-pressure side pipelinecorrespondingly. According to the adsorption type compressor, the refrigeration temperature 120K or below is realized in a mode that semiconductor refrigeration and throttling refrigeration are coupled, and the circulation of refrigerant gas is realized through the adsorption type compressor.

Description

technical field [0001] The invention relates to the technical field of semiconductor refrigerators, adsorption compressors and throttling refrigerators, in particular to an adsorption compressor based on semiconductor refrigeration and a low-temperature refrigerator driven by the same. Background technique [0002] Micro-electromechanical system processing technology has opened up a new direction for the miniaturization of throttling refrigerators, but at this stage, the cold heads of micro-throttling refrigerators mainly rely on relatively large gas cylinders to provide high-pressure gas sources. Such an open refrigeration system has a large overall volume, which largely limits the application potential of micro-throttling refrigerators. To reduce the overall volume of the refrigeration system, a micro-compressor matching the cold head of the micro-throttling refrigerator is required to provide a high-pressure air source for the cold head of the micro-throttling refrigerato...
