Description

Technical Field

[0001] The present application relates to an immersion dielectric composition, and more particularly, to an immersion dielectric composition comprising a fluorinated organic compound, a fluorinated polymer, perfluoromethyl hexanone, a fluorinated ether, and a perfluorosiloxane. Background Art

[0002] In today's society, with the development of the digital economy and the demand for digitalization and energy storage in energy conservation and carbon reduction, it has promoted the breakthrough and integrated development of technologies such as big data, cloud computing, artificial intelligence, the Internet of Things, blockchain, as well as energy storage cabinets, energy storage boxes, and energy storage power stations. Inevitably, higher requirements will be imposed on basic equipment. When hardware equipment processes a large amount of data, it will emit a large amount of heat. How to efficiently, environmentally friendly, and safely cool the hardware equipment and the safety of energy storage-related batteries and prevent related disasters are the problems we need to solve.

[0003] The current cooling methods are as follows: First, traditional air cooling. This traditional cooling method relies on air to take away heat, and the heat conduction is only 4% of that of immersion dielectric fluid. Moreover, the noise is 13 ± 2 dBA higher than that of immersion dielectric fluid, and the power consumption increases by 28%. Second, indirect cooling coolant. The main components of this coolant are ultrapure water and propylene glycol. The advantages of this coolant are low price and environmental friendliness, but it also has fatal disadvantages. If there is a leakage, it will cause fatal damage to the hardware equipment. Secondly, there is a limit to its service life. Third, mineral oil cooling. This cooling method is mostly used in some mechanical equipment. The advantages are low price, insulation, and non-flammability, but it also has disadvantages. It is easy to decompose after long-term use, has a high viscosity, is difficult to clean the equipment, and has a risk of combustion in special cases. Summary of the Invention

[0004] In view of the above problems in the existing cooling methods, the present invention provides an immersion dielectric composition, which can be used as an antifreeze and auxiliary heat dissipation and heat transfer working fluid.

[0009] 7.5 - 14 parts by weight of a fluorinated ether; and

[0010] 0.075 - 0.4 parts by weight of a perfluorosiloxane.

[0011] In one embodiment of the present invention, the above perfluorinated organic compound is selected from the group consisting of octadecafluorooctane (perfluorooctane), perfluorotriethylamine, perfluoro-2-butyltetrahydrofuran, perfluorohexane-1-sulphonic acid, and perfluoro(2-methyl-3-pentanone).

[0012] In one embodiment of the present invention, the above fluoropolymer is selected from the group consisting of hexafluoropropene dimer and hexafluoropropene trimer.

[0013] In one embodiment of the present invention, the above fluorinated ether is selected from the group consisting of 1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxybutane, 1,1,2,2-tetrafluoroethyl 2,2,2-trifluoroethyl ether, 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropylether, and ethyl 1,1,2,2-tetrafluoroethyl ether.

[0014] In one embodiment of the present invention, the above-mentioned perfluorosiloxane is selected from the group consisting of (Heptadecafluoro-1,1,2,2-tetradecyl)trimethoxysilane, Triethoxy-1H,1H,2H,2H-tridecafluoro-n-octylsilane, 1H,1H,2H,2H-Perfluorodecyltrimethoxysilane, 3,3,3-Trifluoropropylmethyldimethoxysilane, and 1H,1H,2H,2H-perfluorooctyl trichlorosilane.

[0015] By optimizing the ratio of each component in the various organic fluorine compounds contained in the immersion dielectric composition, and by introducing perfluorosiloxane (to improve insulation performance) and perfluoroketone (to achieve automatic fire extinguishing), the immersion dielectric composition of the present invention can achieve high-efficiency heat dissipation, environmental protection, energy conservation, safety, insulation, etc. during equipment cooling (immersing the heat-generating electronic device or battery and components in the dielectric fluid), and can also achieve the fire extinguishing effect by means of the dielectric fluid with fire extinguishing efficacy when an electrical disaster occurs, etc. Detailed implementation mode
