Problems solved by technology

Since water is easy to introduce impurity ions to reduce electrical insulation, it is easy to cause short circuit of equipment
Mineral oil has high electrical insulation performance, but mineral oil is flammable, once the equipment generates electric sparks or has external fire sources, static electricity, etc., it is easy to burn and explode

Embodiment 1

[0017] Replace the shell of an ordinary desktop computer host with a liquid cooling device. The liquid cooling device is equipped with a cooling liquid and a heat exchange pipe network. The heat exchange pipe network is suspended above the cooling liquid, and all the accessories of the main computer are immersed in the cooling liquid. The gas formed by the vaporization of the cooling liquid when it meets heat is cooled down when it flows upwards and touches the heat exchange pipe network (passing ordinary tap water into the heat exchange pipe network for cooling). Computer host external display. Check the CPU temperature by installing Master Lu. The fuselage is equipped with a digital display thermometer to display the coolant temperature, and the computer configuration is shown in Table 2 below:

Abstract

The invention discloses an immersed phase change cooling medium and application thereof in a cooling system of an electronic device. The cooling medium is one or a mixture of two or more of perfluoro-4-methyl-2-pentene, perfluoro-2-methyl-3-pentanone, perfluoro-2-methyl-2, 3-epoxypentane and perfluorohexanone. The immersed phase-change cooling medium provided by the invention has the characteristics of high electrical insulation property, low viscosity, lower boiling point, high gasification latent heat, good compatibility and stability, incombustibility, combustion inhibition, low global warming potential (GWP), zero ozone consumption potential (ODP) and the like.

Description

technical field [0001] The invention belongs to the field of liquid cooling medium, in particular to an immersion type phase change cooling medium and its application in the cooling system of electronic equipment. Background technique [0002] In today's society, with the vigorous development of artificial intelligence, cloud computing, blockchain, and big data technologies, the actual business has higher and higher performance requirements for the underlying IT infrastructure, which directly leads to an increase in the power consumption of infrastructure such as servers. When the number of servers in a single cabinet remains unchanged, the power consumption of the entire data center cabinet presents a trend of rapid growth, which brings unprecedented challenges to the heat dissipation of the computer room, which has also become a major bottleneck restricting the development of the data center. [0003] At present, the commonly used heat dissipation methods in data centers a...
