Embodiment approach
[0034]In an optional embodiment of the present invention, the refrigerant medium is perfluoro-2-methyl-2,3-epoxypentane, perfluoro-4-methyl-2-pentene, perfluorohexanone , perfluorohexane, perfluoropentane, one, two, three or any combination of components.
[0035] Optionally, when the cold medium is a mixture of two or more components, the mass proportion of each component is 4-70%, calculated by taking the total mass of the composition as 100%.
[0036] Compared with the prior art, the beneficial effects of the embodiments of the present invention are reflected in:
[0037] 1) The refrigerant medium provided by the embodiments of the present invention has high electrical insulation performance, low viscosity, low boiling point, low dielectric constant (low polarity), high thermal conductivity, high latent heat of vaporization, good compatibility and stability , non-flammable and inhibited combustion, low global warming potential (GWP), zero ozone depletion potential (ODP) an...
Embodiment 1
[0049] Place the desktop computer host in a closed liquid cooling device. The liquid cooling device is equipped with cooling liquid and heat exchange pipe network. The heat exchange pipe network is suspended above the cooling liquid. All accessories of the main computer are immersed in the cooling liquid. Use perfluoro-4-methyl-2-pentene as cooling liquid. The CPU generates heat during operation, and the gas formed by the vaporization of the coolant when it encounters heat is cooled down when it flows upwards and touches the heat exchange pipe network (the heat exchange pipe network is passed into ordinary tap water for cooling). Computer host external display. The temperature of the CPU and GPU is detected through the CPU-Z program, and the body is equipped with a digital display thermometer to display the temperature of the coolant. When the CPU and GPU are running at full load, the computer runs smoothly for 24 hours, the CPU temperature is 51°C, the GPU temperature is 62°...
Embodiment 2
[0053] Using the same computer configuration as in Example 1, place the mainframe of the desktop computer in a closed liquid cooling device. The liquid cooling device is equipped with a cooling liquid and a heat exchange pipe network, and the heat exchange pipe network is suspended above the cooling liquid. All accessories of the main computer Submerged in coolant. Perfluorohexanone is used as the cooling liquid. The CPU generates heat during operation, and the gas formed by the vaporization of the coolant when it encounters heat is cooled down when it flows upwards and touches the heat exchange pipe network (the heat exchange pipe network is passed into ordinary tap water for cooling). Computer host external display. The temperature of the CPU and GPU is detected through the CPU-Z program, and the body is equipped with a digital display thermometer to display the temperature of the coolant. When the CPU and GPU are running at full load, the computer runs smoothly for 24 hou...
