THERMOCOMPRESSION DEVICE Russian patent published in 2014 - IPC F17C5/06 F04B19/24 

FIELD: machine building.

SUBSTANCE: thermocompression device comprises a source of high pressure gas with connected cylinders-compressors, connected in parallel into a combined manifold for charging of cylinders-compressors and supply of gas to a consumer at the inlet to a heat-exchanger-cooler and also a source of cold. Each cylinder-compressor is made in the form of a thermally insulated double-wall reservoir with ribbing of the internal vessel located in the wall-to-wall cavity. The wall-to-wall cavity of each thermally insulated double-wall reservoir is connected directly to the common source of cold made in the form of a Dewar flask with liquid nitrogen. In each thermally insulated double-wall reservoir the internal vessel is equipped with an autonomous heater, made in the form of an electric heater from carbon cloth, fixed on the outer wall of the inner vessel and connected to the outer source of power supply. Valves are connected into the combined manifold, installed accordingly at the outlet (inlet) of the high-pressure gas source, of each cylinder-compressor and heat-exchanger-cooler.

EFFECT: improvement and simplification of design and operation of a device for thermocycling of cylinders-compressors and provision of continuous charging of consumer cylinders with gas, preventing its contamination.
