Embodiment 1

[0032] Check the airtightness of the host computer of an ordinary desktop PC, directly add perfluoroamine cooling liquid, and let all the accessories of the computer host be submerged in perfluoroamine for cooling. At the same time, the cold and heat exchange tubes are installed, and the cold and heat exchange tubes are immersed in the perfluoroamine cooling liquid, and tap water is passed through the cold and heat exchange tubes to cool down. Start the program and run the program continuously for one month, and observe the CPU temperature changes. The experimental test results when using different perfluoroamine coolants are shown in Table 2. Wherein, the blank sample in Table 2 refers to: the host computer of the desktop PC uses its own fan to rotate for cooling.

Embodiment 3

[0043] The battery of the new energy vehicle is taken out, and different perfluoroamine cooling liquids are placed in the liquid cooling tube and indirectly contact the battery of the new energy vehicle through the liquid cooling tube. The cooling end of the liquid cooling tube is cooled with tap water. Install a temperature indicator on the battery, and test the temperature change of the battery under cooling with different fluorinated liquids. The test results are shown in Table 4. The blank sample in Table 4 refers to that the battery of the new energy vehicle is cooled by contacting the ambient air.

[0044] Table 4 Experimental test results

[0045]

[0046] Through comparison in Table 4, it is found that the immersion cooling fluid can protect the battery from overheating during operation and keep it at a safe temperature, so that the battery can operate more safely and efficiently.

Abstract

The invention discloses a cooling liquid and an application of the cooling liquid in a cooling system of electronic equipment. The main component of the cooling liquid is a perfluoroamine compound. The perfluoroamine compound is one or a mixture of more than two of perfluorotriethylamine, perfluorotripropylamine, perfluorotributylamine, perfluorotriamyl amine and perfluoroN-methylmorpholine. Whenthe cooling liquid is used for cooling systems of electronic equipment such as a data center server, a super computer, an integrated processing server or an electric vehicle battery pack, the coolingliquid has the characteristics of good heat transfer effect, uniform heat dissipation, stable cooling effect and the like.

Description

technical field [0001] The invention relates to the field of liquid cooling, in particular to a cooling liquid and its application in cooling systems of electronic equipment. Background technique [0002] Nowadays, the semiconductor industry and the new energy automobile industry are developing rapidly along with the upgrading of the technology industry. However, during the operation of high-performance computer hosts, data center servers, and new energy vehicles, a large amount of heat is often generated to reduce operating efficiency and cannot be effectively processed, which has become one of the bottlenecks hindering their development. How to transfer or transform these heats has become a key issue that these new technologies need to consider in terms of site selection, regional temperature, green energy, and power supply and distribution systems. [0003] Therefore, the current energy consumption of the data center is mainly concentrated on the servers that run all yea...
