[0036] A method for preparing an immersion cooling fluid, comprising the following steps:
[0037] A. Weigh raw materials according to the following parts by weight: perfluoropropyl methyl ether 10-20, trans-1,2-dichloroethylene 1-5, isopropanol 1-5, end-capped polyether 70-88; Preferably, the end-capped polyether structure is:
[0038]
[0039] In the formula, m=0~10, n=0~5, m and n are not zero at the same time, R 1 for hydrogen or C 1 ~C 4 alkanes; R 2 is hydrogen or methyl, R 3 for C 2 ~C 5 alkanes, R 4 for where r is hydrogen, C 1 -C 6 Alkyl or C 1 -C 6 cycloalkyl.
[0040] Preferably, the purity of the perfluoropropyl methyl ether is >99%; the purity of the trans-1,2-dichloroethylene is >99.5%; and the purity of the isopropanol should be >99%.
[0041] B. Add perfluoropropyl methyl ether, trans-1,2-dichloroethylene, and isopropanol into the reaction kettle at 20-60°C under nitrogen, and stir for 10-30 minutes to form solution 1;
[0042] C. Add the end...
