Description

technical field [0001] The invention relates to the technical field of cooling liquid, in particular to a multi-effect organic cooling liquid composition and its application, which can be applied in cooling systems of low-temperature environment equipment such as radars and lasers. Background technique [0002] With the continuous development of military electronic equipment technology and electronic laser technology, the calorific value and heat flux density of devices are getting higher and higher. Traditional air-cooled heat dissipation can no longer meet the increasing heat flux density requirements. Liquid cooling is becoming the first choice for radar and electronic laser heat dissipation. One of the main technical approaches.

AI Technical Summary

Problems solved by technology

At present, commonly used coolants mainly include water, alcohols (ethylene glycol aqueous solution, propylene glycol aqueous solution), polyalphaolefin (PAO), silicates, mineral oils and fluorocarbons, among which water is the most common and Very efficient cooling medium, which is widely used in industry and life, but due to its corrosiveness and freezing point, it cannot meet the environmental adaptability requirements of the cooling system

Ethylene glycol aqueous solution is currently the most commonly used cooling medium due to its low freezing point, low corrosiveness, high specific heat capacity, and good fluidity. However, it will oxidize under high-temperature thermal load operating conditions. The cooling system is filled with air and uses a large amount of copper and copper alloys. The components will promote the oxidation of ethylene glycol to form a mixed acid with formic acid as the main corrosive effect. This solution is more corrosive than tap water without coolant

PAO belongs to oil, insoluble in water, and can burn when exposed to open flames, and its safety is poor

After a certain period of storage and use, the stability of silicates becomes poor, and it is easy to form gel-like substances to precipitate, which affects the cooling effect

Mineral oils create a mess and make maintenance difficult

[0003] There are some problems in the current radar and laser coolants. For example, Chinese patent CN109762533A discloses a multi-effect, low-foaming organic radar coolant and its application. It is based on ethylene glycol and deionized water and uses organic compound slow Corrosion agent, using the synergistic effect between organic corrosion inhibitors to improve the corrosion inhibition effect of anti-corrosion corrosion inhibitors, but its composition is relatively complex, and additional defoamers need to be added; Chinese patent CN105038727A discloses a cooling liquid , using oligosaccharides as free radical scavenger, polyols as organic additives, and quaternary ammonium salts as flow drag reducers and pipeline preservatives to prepare a non-corrosive and pollution-free cooling fluid, but oligosaccharides are easy to decompose at high temperatures, affecting Therefore, it is imperative to develop a radar and electronic laser coolant that can achieve multi-effect protection for metal and non-metal materials
