Problems solved by technology

This product has a good anti-corrosion effect on copper, brass, steel, cast iron, solder, cast aluminum and other materials, but it has no anti-corrosion effect on zinc, nickel, magnesium and some emerging materials. At the same time, the efficiency of the cooling liquid needs to be improved. Pollution is also getting worse
Therefore, the traditional thermal management system fluid cannot meet the environmental requirements and heat management of precision equipment

Abstract

The invention discloses a thermal management system liquid composition, which is prepared from the following raw materials in parts by weight: 20 to 40 parts of polyether, 0.1 to 5 parts of preservatives, 0.5 to 4 parts of antirust agents, 0.01 to 1.5 parts of triazole compounds, 0.2 to 3 parts of antioxidants, 0.001 to 0.1 part of odorizers, 0.001 to 0.005 part of defoaming agents and 60 to 80 parts of deionized water. The composition provided by the invention has the advantages of good anti-corrosion effect, high heat conductivity coefficient, oxidation resistance and good thermal stability.

Description

technical field [0001] The invention belongs to the technical field of thermal management and relates to a thermal management system liquid composition. Background technique [0002] With the improvement of the degree of refinement of various mechanical and electronic equipment, heat management has gradually received attention. Accurate thermal management is conducive to the normal operation and extended service life of equipment. The thermal management system fluid is a fluid that precisely manages the heat of the equipment. It can take away the heat generated by the equipment in time, and can also provide the required heat for the normal operation of the equipment. Such as car engine coolant can take away the heat generated by the engine. For electric vehicles, the coolant can provide the required heat for starting. For radar equipment, the precise control of temperature has a great relationship with the accuracy of equipment use, and the thermal management system fluid...
