Description
Technical Field
The invention relates to an electronic device cooling liquid and a preparation method thereof.
Background
With the rapid development of the information-oriented society of China and the rise of industries such as cloud computing and the Internet of things, the computer technology enters a rapid development stage, and the performance requirements of people on IT equipment are higher and higher. With the performance improvement of IT devices and the development trend of high integration and miniaturization of electronic devices, the power consumption of IT devices is increased, so that the heat dissipation problem is more prominent.
At present, the commonly used heat dissipation mode of the electronic device is air-cooled heat dissipation, namely air is used as a cooling medium to cool the electronic device, but the traditional air-cooled heat dissipation cannot meet the heat dissipation requirement along with the continuous rising of the power consumption and the integration level of the electronic device. Liquid cooling heat dissipation is mainly to take away waste heat generated by a heating element through direct contact of cooling liquid. The heat carrying capacity of the working medium, which is reflected by the product of the density and the specific heat of the cooling liquid, is nearly 2000 times higher than that of air-cooled heat dissipation, so the liquid-cooled heat dissipation becomes the mainstream technology of heat dissipation in the future.
The liquid cooling heat dissipation comprises an immersion type liquid cooling and a spraying type liquid cooling, wherein the spraying type liquid cooling adopts insulating cooling liquid to spray on the heating electronic device to take away waste heat of the electronic device, so that the purpose of quickly dissipating heat of the electronic device is achieved. Because the cooling liquid directly contacts with the electronic device and is suitable for a relatively open spraying liquid cooling system, higher requirements are provided for the insulativity, the liquidity, the volatility, the chemical stability and the like of the cooling liquid. At present, the IT equipment is cooled by commonly used organic fluoride, but the organic fluoride has high cost and high density, has a certain destructive effect on the environment and influences the popularization and the application of the organic fluoride. Common mineral oil is also used as the cooling liquid, but the common mineral oil has poor insulating effect, relatively high viscosity and poor fluidity.

Example 1
The cooling liquid for the electronic device comprises the following components in percentage by mass: 99.0 to 99.9 percent of base oil, 0.005 to 0.9 percent of dispersant and 0.005 to 0.5 percent of antioxidant; viscosity of base oil μ: mu is more than or equal to 5 and less than or equal to 30cst or mu is more than 40 and less than or equal to 50 cst; the sum of the contents of the components is 100 percent.

The preparation method of the electronic device cooling liquid specifically comprises the following steps:
s1, respectively weighing the following components in percentage by mass:
99.0 percent of dimethyl silicone oil, 0.9 percent of polyethylene glycol and 0.1 percent of 2, 6-di-tert-butyl-p-cresol;
s2, mixing the dimethyl silicone oil weighed in the step S1 and the 2, 6-di-tert-butyl-p-cresol, heating to 60 ℃, stirring until the mixture is transparent, and then cooling to room temperature of 25 ℃;

In this embodiment, the base oil is a natural ester oil with a viscosity of 30cst, the dispersant is a polyglycerol ester, the dispersant is 0.495% by mass, and the antioxidant is an antioxidant 1076, which is β - (3, 5-di-tert-butyl-4-hydroxyphenyl) n-octadecyl propionate, and the mass percentage of the antioxidant is 0.005%.
The preparation method of the electronic device cooling liquid in this example is the same as that in example 1 (the steps are the same, and only the specific raw materials and mass percentages are different), and details are not repeated. The subsequent steps of preparing the electronic device cooling liquid of examples 3 to 7 were the same as in example 1.
Example 1 and example 2 the cooling fluid and conventional mineral oil performance index tests were compared as follows:
| performance index | Common mineral oil | Example 1 | Example 2 | Test standard |
| Viscosity of the oil | 26.5 | 23.5 | 36 | GB/T 265 |
| Flash point. C | 185 | 245 | 319 | GB/T |
| Breakdown voltage KV | 25 | 71.8 | 54.4 | GB/T 507 |
| Loss by weight of evaporation | 1.40％ | 1.85％ | 1.18％ | GB/T 7325 |
| Acid value mgKOH/g | 0.02 | 0.01 | 0.03 | GB/T7304 |
(Table 1)
As can be seen from Table 1, the cooling liquid in example 1 has a viscosity of 23.5, which meets the flow requirement of spraying liquid cooling, but the lower the viscosity, the higher the volatility, the higher the loss and the easy fire-fighting hazard; the flash point and the breakdown voltage of the cooling liquid in the embodiment 1 are much higher than those of common mineral oil, which shows that the insulating property and the fireproof property are greatly improved; the evaporation loss of the cooling liquid in the embodiment 1 is slightly larger than that of the common mineral oil, and the loss is slightly increased; the acid value of the cooling liquid of example 1 was lower than that of ordinary mineral oil, and the corrosiveness was reduced. As can be seen,
the overall performance of example 1 is better improved compared to conventional mineral oils.
The viscosity of the cooling liquid in the embodiment 2 is 36, the flowing requirement of spraying liquid cooling is met, compared with the embodiment 1, the viscosity is increased, the volatility is reduced, the loss is reduced, the fire-fighting hidden danger is not easy to generate, but if the viscosity is too high, the pumping power of the system needs to be improved, and thus the energy-saving and environment-friendly requirements are not met; in the embodiment 2, the flash point and the breakdown voltage of the cooling liquid are much higher than those of common mineral oil, which shows that the insulating property and the fireproof property are greatly improved; in the embodiment 2, the evaporation loss of the cooling liquid is less than that of common mineral oil, and the loss is reduced; the acid value of the cooling liquid of example 2 is slightly lower than that of the common mineral oil, and the corrosiveness is slightly higher. It can be seen that the overall performance of example 2 is better improved compared to conventional mineral oils.
Example 1 and example 2 coolant heat rejection parameters are as follows:
(Table 2)
As can be seen from table 2, when the cooling liquids of example 1 and example 2 are used to cool the electronic device, compared to the conventional air cooling mode, the cooling liquids of example 1 and example 2 can obtain a lower temperature difference, which indicates that the cooling liquid has a significantly higher ability to remove heat from the electronic device (e.g., GPU) than the conventional air cooling.

In this example, the viscosity of 20cst dimethicone was 99.4% by mass, the polyethylene glycol was 0.595% by mass, and the 2, 6-di-t-butyl-p-cresol was 0.005% by mass.
Example 4

In this example, the base oil was dimethicone with a viscosity of 40cst of 99.5% by mass, and the antioxidant was 2, 6-di-tert-butyl-p-cresol of 0.5% by mass.
The preparation method of the electronic device cooling liquid specifically comprises the following steps:

Example 8 comparison of coolant and common mineral oil performance index tests, the following table:
| performance index | Common mineral oil | Example 8 | Test standard |
| Viscosity of the oil | 26.5 | 39 | GB/T 265 |
| Flash point. C | 185 | 310 | GB/T |
| Breakdown voltage KV | 25 | 84.4 | GB/T 507 |
| Loss by weight of evaporation | 1.40％ | 1.05％ | GB/T 7325 |
| Acid value mgKOH/g | 0.02 | 0.01 | GB/T7304 |
(Table 3)
As can be seen from table 3, the viscosity 39 of the cooling liquid of example 8 satisfies the flow requirement of the spray liquid cooling; in example 8, the flash point and the breakdown voltage of the cooling liquid are much higher than those of common mineral oil, which shows that the insulating property and the fireproof property are greatly improved; example 8 the evaporation loss of the cooling liquid is less than that of the common mineral oil, and the loss is reduced; example 8 the acid value of the cooling fluid was lower than that of ordinary mineral oil and the corrosiveness was reduced.
