Description

Technical Field

[0001] This application relates to a multifunctional two-phase immersion coolant composition, specifically, to a multifunctional two-phase immersion coolant composition comprising perfluorohexanone, fluorinated ethers, hexafluoropropylene polymers, and fluoropolymers. Prior Technology

[0002] In today's society, the development of the digital economy and the demand for digitalization and energy storage driven by energy conservation and carbon reduction have promoted the breakthrough and integrated development of technologies such as big data, cloud computing, artificial intelligence, the Internet of Things, blockchain, and energy storage cabinets, energy storage boxes, and energy storage power stations. This will inevitably place higher demands on basic equipment. Hardware equipment will generate a lot of heat when processing large amounts of data. How to efficiently, environmentally friendly, and safely cool down hardware equipment, as well as the safety of energy storage batteries and the prevention of related disasters, are the problems we need to solve.

[0003] Currently, there are several cooling methods: First, traditional air cooling, which relies on air to carry away heat. Its heat conduction is only 4% that of immersion dielectric fluid, and its noise level is 13±2 dBA higher, while its power consumption is 28% higher. Second, indirect cooling coolant, whose main components are ultrapure water and propylene glycol. This coolant is inexpensive and environmentally friendly, but it has fatal flaws: leaks can cause severe damage to the equipment, and it also has a limited lifespan. Third, mineral oil cooling, mostly used in mechanical equipment. Its advantages include low cost, insulation, and non-flammability, but it also has disadvantages: it decomposes easily over time, has high viscosity, is difficult to clean, and poses a risk of combustion in special circumstances. Summary of the Invention

[0004] In view of the aforementioned problems with the cooling methods of the prior art, the present invention provides a multifunctional two-phase immersion coolant composition, which can be used as a working fluid for antifreeze, auxiliary heat dissipation, and heat transfer.

[0005] To achieve the above and other objectives, the present invention provides a multifunctional two-phase immersion coolant composition, comprising: 40-60 parts by weight of perfluorohexanone; 4-20 parts by weight of fluorinated ethers; 20-50 parts by weight of hexafluoropropylene polymer; and 1-3 parts by weight of fluoropolymer.

[0006] In one embodiment of the present invention, the fluoropolymer in the above-mentioned multifunctional two-phase immersion coolant composition may be a fluorinated acrylate polymer.

[0007] In one embodiment of the present invention, the above-mentioned hexafluoropropene polymer system is selected from the group consisting of hexafluoropropene dimer and hexafluoropropene trimer.

[0008] In one embodiment of the present invention, the above-mentioned fluorinated ethers are selected from the group consisting of methyl nonafluorobutyl ether, 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether and ethyl 1,1,2,2-tetrafluoroethyl ether.

[0009] This invention optimizes the proportions of various components in multiple organofluorine compounds, introducing perfluoropolymers (waterproof, moisture-proof, and corrosion-resistant) and perfluorohexanone (for automatic fire extinguishing). In equipment cooling (immersing heat-generating electronic devices in coolant), it can achieve advantages such as efficient heat dissipation (two-phase immersion), environmental protection (ODP: 0, GWP < 10), energy saving, safety (moisture-proof and corrosion-resistant), insulation, and fire extinguishing.
