Description
technical field [0001] The invention relates to a gas-sensing-oriented miniature multifunctional structure liquid leakage detector, which belongs to the technical field of phased array antenna cold plate liquid leakage detection instruments. Background technique [0002] Active phased array radar will generate extremely high heat flux density when it is working, and it usually uses a liquid-cooled cold plate to dissipate heat. The lowest freezing point of ethylene glycol-based coolant can reach -68°C. It has good antifreeze performance, high boiling point, low foam tendency, good viscosity-temperature performance, anti-corrosion and anti-scaling, etc. It is widely used in phased array radar, aviation, automobile, etc. In cooling systems such as engines. In the actual engineering application of coolant, micro-scale leakage is often encountered. Due to the small leakage and the viscosity and surface tension of the liquid working fluid, it is difficult to effectively measure t...
