[0003] Radar and wind power heat exchange fluid media can be divided into water-type heat exchange fluid media and non-aqueous heat exchange fluid media according to the evaluation of the impact on radar and wind power working systems. Currently, radar and wind power heat exchange fluid media commonly used in the market are mostly Water-type heat exchange fluid medium, water-type heat exchange fluid medium has high heat exchange efficiency and good anti-corrosion effect, but its fatal disadvantage is its high electrical conductivity. Once leaked in the working environment, it is easy to cause short-circuit and burn the electronic system and cannot continue to work. The protection performance of the working medium with high conductivity cannot meet the long-term working requirements. The water-type heat exchange fluid medium has a low boiling point and is easy to evaporate. It needs to replenish deionized water from time to time, and maintenance is not very convenient. In addition, the general water-type heat exchange fluid medium , Ethylene glycol is used as antifreeze in production. Ethylene glycol is toxic and not easy to biodegrade

Description

technical field [0001] The invention relates to a non-aqueous glycol ether-based heat-exchange fluid medium that provides comprehensive protection for radar and wind power heat-exchange systems. Background technique [0002] Radar and wind power heat exchange fluid medium is a low freezing point liquid loaded in radar and wind power systems for all-weather work. It can not freeze at low temperatures, has good fluidity, and has little evaporation at high temperatures. It is a heat exchange fluid medium that takes away a large amount of heat generated by radar and wind power during operation, adapts to various complex working environments, and has low conductivity in the case of leakage, and will not cause short circuits in electronic systems such as radar and wind power. , to ensure that the radar still has continuous working ability when the power-on time is greater than 100h, and it can have long-term anti-foaming, anti-boiling, anti-corrosion, anti-scaling, anti-freezing, ...
