A capillary driven flat plate evaporator fluid circuit

Abstract

The invention discloses a fluid circuit of a capillary force-driven flat plate evaporator, which comprises a flat plate evaporator (1), a steam pipeline (2), an auxiliary condensation pipe (3), a capillary evaporator (4), a main The condensing pipe (5) and the liquid pipeline (6), the auxiliary condensing pipe (3) and the main condensing pipe (5) are wound on the condensing column (10), and the steam pipeline (2) is connected to the gas storage chamber (7); The flat plate evaporator (1) includes a heat conduction plate (8) and a serpentine pipe (9) embedded in the upper channel of the heat conduction plate (8); the plate evaporator (1) is coupled with an infrared heat source, and the condensation column (10) is coupled with a refrigerator ; The capillary evaporator (4) is in direct contact with the condensation column (10). The invention adopts the form of a flat plate evaporator and only includes one capillary evaporator, and realizes the miniaturization of the structure while solving the supercritical start-up of the cryogenic heat transfer device.

Description

A capillary force-driven flat plate evaporator fluid circuit technical field The present invention relates to the cryogenic heat transfer device of space application background, particularly a kind of evaporator driven by capillary force fluid circuit. Background technique In the face of space-based infrared satellites etc. to the special demand of space cold source, must be in infrared detector and space deep low temperature refrigeration Create a "bridge" between the cold machines, that is, the cryogenic heat transfer device. In addition to the need to achieve cryogenic conditions, the cryogenic heat transfer device The high-efficiency collection and transmission of heat will also have the function of isolating or reducing mechanical vibration and electromagnetic interference. for space applications Background, at present, the cryogenic heat transfer device mainly needs to solve two technical problems: 1) solve the supercritical start-up from the normal temperature...
