Embodiment 1
[0015] A heat dissipation working fluid for phase change radiators, including 7g n-octadecane, 10g sodium dodecylbenzenesulfonate, 10g butanediol, 0.2g ethanol, 0.2g n-propanol, 0.2g isopropanol Alcohol, 0.12g sodium chloride, 0.18g potassium chloride and 72.1g distilled water.
[0016] The preparation process of heat-dissipating working fluid described in the present invention is introduced in detail below:
[0017] In the first step, select 72.1g distilled water, 7g n-octadecane, 10g sodium dodecylbenzenesulfonate, 10g butanediol, 0.2g ethanol, 0.2g n-propanol, 0.2g isopropanol, 0.12g chlorine Sodium chloride, 0.18g potassium chloride;
[0018] In the second step, the ethanol, n-propanol, and isopropanol of the above-mentioned quality are successively put into the above-mentioned distilled water, and fully stirred to obtain the mixed solution A1;
[0019] In the third step, the n-octadecane of the above quality is put into the mixed solution A1, and fully stirred to obtain...
Embodiment 2
[0023] A heat dissipation working fluid for a phase change radiator, including 35g n-octadecane, 10.5g octadecyl polyoxyethylene ether, 10g ethylene glycol, 3g ethanol, 3g n-propanol, 3g isopropanol, 0.6g sodium chloride, 0.9g potassium chloride and 14g distilled water.
Embodiment 3
[0025] A cooling fluid for phase change radiators, including 17g n-octadecane, 10g octadecyl polyoxyethylene ether phosphate, 8g ethylene glycol, 3g ethanol, 3g n-propanol, 3g isopropanol , 1g sodium chloride, 1.5g potassium chloride and 53.5g deionized water.
[0026] The preparation process of Embodiment 2 and Embodiment 3 is the same as that of Embodiment 1, and will not be repeated here.
[0027] Table 1: Comparison of experimental data
[0028]
[0029] It can be seen from the above table that the heat-dissipating working medium prepared by mixing the mass fractions of the present invention has a higher specific heat capacity, better heat transfer effect, and is not easy to solidify in a low temperature environment, and the working state is relatively stable, and the technical effect is equivalent. obvious.
