Passively cooled capillary drain tube and method for a two-phase fluid circuit reservoir

Abstract

The invention discloses a passive cooling capillary drainage pipe and method for a two-phase fluid loop liquid storer. The passive cooling capillary drainage pipe penetrates through a liquid storer shell, and communicates with an external fluid loop system; and when liquid to be cooled passes through the liquid storer, the passive cooling capillary drainage pipe is used for cooling. A heat exchange mode is adopted to cool the internal of the liquid storer; a temperature control function is achieved only through adjustment of the heating power consumption, so that the structure of the liquid storer is prominently simplified; and meanwhile, the drainage pipe can be locally located in a colder state always, so that bubbles near the drainage pipe are effectively prevented, and emissions of theliquid storer are guaranteed as liquid-phase working mediums.

Description

technical field [0001] The invention relates to the technical field of spacecraft thermal control, in particular to a passive cooling capillary drain pipe and method for a two-phase fluid circuit liquid storage device. Background technique [0002] With the rapid development of aerospace technology, the thermal control requirements of high load, large heat flux density, long-distance heat transfer and high-precision temperature control are becoming more and more obvious.

Problems solved by technology

The liquid receiver refrigeration of AMS-02 is realized by the semiconductor refrigeration chip, and the heat conduction of the semiconductor cooling surface is installed on the outer surface of the liquid receiver shell, and the cold energy is transferred to the inside of the liquid receiver through the side wall of the liquid receiver. Large power consumption, low cooling efficiency, low utilization rate of cooling capacity, and the need for control circuits to regulate, which makes the structure of the liquid receiver more complex, greatly reducing the reliability of the system, and the semiconductor cooling chip will generate a lot of waste heat at the same time, Still need other cooling capacity
