Abstract

The invention discloses an immersed cooling fluid and a preparation method thereof. The cooling fluid comprises the following raw materials in parts by weight: perfluoropropyl methyl ether 10-20, trans-1,2-dichloroethylene 1-5, iso- Propanol 1-5, end-capped polyether 70-88. Preparation method: comprising the following steps: A. Weighing raw materials according to the following parts by weight: perfluoropropyl methyl ether 10-20, trans-1,2-ethylene dichloride 1-5, isopropanol 1-5, sealing Terminated polyether 70-88; B. At 20-60°C, under nitrogen conditions, add perfluoropropyl methyl ether, trans-1,2-dichloroethylene and isopropanol into the reaction kettle, stir for 10-30 minutes to form solution 1; C. At 50-70° C., under nitrogen conditions, the end-capped polyether is added to solution 1, stirred for 30-60 minutes, and filtered to obtain the product. The cooling fluid of the invention is clear and transparent, has high dielectric strength, is incombustible, and has a large thermal conductivity; the preparation process is simple, safe, and has industrial application value.

Description

technical field [0001] The invention belongs to the technical field of cooling, and relates to a cooling fluid and a preparation method thereof, in particular to an immersion cooling fluid and a preparation method thereof. Background technique [0002] With the development of new energy technologies, various electronic devices are widely used, such as supercomputers, radars, 5G base stations, etc. Heat dissipation is a prominent factor in the design and application of these devices. How to effectively reduce the operating temperature of the device and keep the device running efficiently, stably, and for a long period of time is the biggest challenge. At present, the traditional cooling fluid (coolant / cold water) combined with the design of the cooling system (device) is the main solution. CN201720033007.2 designed a full immersion cooling device, which can ensure the stable and efficient operation of the server, and solve the problems of excessive local temperature and high...
