Two-phase fluid circuit condenser structure

Abstract

The invention provides a two-phase fluid loop condensation pipe structure. The two-phase fluid loop condensation pipe structure comprises a condensation pipe body, wherein a liquid flow channel and asteam flow channel are formed inside the condensation pipe body in the length direction of the condensation pipe body, the liquid flow channel and the steam flow channel are communicate through a communication slit, the cross section size of the steam flow channel is larger than the cross section size of the liquid flow channel, and the cross section size of the liquid flow channel is larger thanthe cross section size of the communication slit. According to the two-phase fluid loop condensation pipe structure, due to the design of the steam flow channel and the liquid flow channel, gas and liquid can be effectively separated in the condensation process, and the conduction thermal resistance caused by a liquid film and a liquid plug is reduced; according to the tail end of the flow direction of the condensation section, the liquid flow channel is connected with an outlet, the steam flow channel is closed, and steam can be prevented from being discharged from the outlet by controlling the liquid filling rate in the two-phase fluid loop.

Description

technical field [0001] The invention relates to a condensation pipe structure of a two-phase fluid circuit, in particular to a solid structure of a steam condensation section of a gas-liquid separation type two-phase fluid circuit. Background technique [0002] Existing two-phase fluid loop technologies mainly include split gravity heat pipes, loop heat pipes, capillary suction loops, and pump-driven two-phase fluid loops. Except for a few gas-liquid mixing pump-driven two-phase fluid circuits, the mainstream in industrial applications is gas-liquid separation two-phase fluid circuits, whether driven by a pump or not. These two-phase fluid circuits all need to condense all the steam in the condensation section, so that all the working fluid becomes liquid before returning to the evaporator. In the condensation section of various gas-liquid separation two-phase fluid circuits, except for a few loop heat pipes for pure scientific research, which use reverse capillary cores an...

In addition, in a microgravity environment, the annular condensate film in the circular tube lasts longer and is less likely to be damaged by steam flow, resulting in earlier formation of the thermal resistance of the pipeline and a greater negative impact on heat conduction
