Description
Technical field [0001] The invention relates to a gas sensing-oriented liquid leakage detector with a miniature multifunctional structure, which belongs to the technical field of liquid leakage detectors for phased array antenna cold plates. Background technique [0002] Active phased array radars produce extremely high heat fluxes when they work, and liquid-cooled cold plates are usually used to dissipate heat. The lowest freezing point of glycol-based coolant can reach -68℃, and it has good antifreeze performance. It has the characteristics of 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 In the cooling system of the engine. In the actual engineering application of coolant, it is often encountered with micro-scale leakage. Due to the small leakage and the viscosity and surface tension of the liquid working fluid, it is difficult to effectively me...
