Microgravity environment-based spray cooling loop device

Abstract

The invention discloses a microgravity environment-based spray cooling loop device. According to the device, a heat sink is arranged on a liquid storage component; a hydraulic driving pipeline is provided with a micro high pressure diaphragm pump; two ends of the hydraulic driving pipe are communicated with a liquid collector and a spray component respectively; three hole drain pipes of the liquid collector are inserted into a second capillary core of the liquid storage component; and the spray component and the liquid storage component are connected through a steam collecting pipeline, a first liquid collecting pipeline and a second liquid collecting pipeline. The device generates high-speed atomized liquid drops under high pressure impact, and the high speed atomized liquid drops impact the surface of the first capillary core connected with a heat source to take away heat generated by the heat source in heat transfer modes such as forced convection, boiling, evaporation phase change and the like. By the capillary characteristics of the capillary core, the device collects and circulates the liquid under microgravity environment; and moreover, a steam collector, a steam condenser and the liquid collector are integrated into a unit, so the volume is reduced.
