Computer coolant and application thereof

Abstract

The invention provides a computer coolant. The computer coolant is prepared from the following components in percentage by weight: 1000-2000 parts of N-methyl pyrrolidone, 200-400 parts of glycol, 0.5-5 parts of a silane coupling agent, 0.5-5 parts of silicone, 0.5-2 parts of 1-hexyl-2,3-dimethylimidazolium hexafluorophosphate, 0.5-2 parts of N-butylpyridinium hexafluorophosphate, 0.1-0.5 part ofcopper powder, 0.1-0.5 part of graphite powder, and 0.1-0.5 part of a defoamer. The computer coolant has the steam pressure close to zero, thus is not liable to volatilize, meanwhile has high thermalconductivity, the high specific heat, the low solidification point, the low viscosity and the high flash point and has good compatibility with materials such as fluid pipelines of cooling systems andmetals and rubber of accessories, and the coolant is also environmentally friendly and good in environmental protection. The computer coolant can be applied as the computer coolant and can also be applied as an engine coolant.

Description

technical field [0001] The invention relates to a novel computer cooling liquid, which is mainly used in the heat dissipation system of a large power consumption chip on a computer, and belongs to the field of chemical industry. Background technique [0002] With the development of microelectronics technology, the power consumption of chips is getting higher and higher, and thermal design is also facing important challenges. For computers, the frequency of CPU, graphics card, and memory is constantly increasing, and the heat generated will affect the normal operation of the computer and even damage the computer hardware. Therefore, the design of the computer cooling system and the selection of cooling media are very important. [0003] In the early days, the traditional heat dissipation method of computers was usually passive natural cooling. With the upgrade of chip power consumption, active media heat dissipation appeared: forced air cooling and liquid heat dissipation. C...

Problems solved by technology

Among the three, the advantages of air cooling are simple structure, low price, safety and reliability, and mature technology. The disadvantages are that the temperature cannot be lowered below room temperature, the fan rotation causes noise, and the fan life has a time limit; the advantage of water as a cooling medium is the cooling capacity. Strong, no vibration, and reduces the probability of computer failure caused by overheating. The disadvantage is that water will corrode the cooling system and generate scale; In terms of lack of pertinence, the nitrite, amine, boron, etc. contained in the engine coolant will damage the computer cooling system, and there is a risk of leakage, pollution of the environment and harm to the human body

The above-mentioned coolant is mainly aimed at the engine cooling system. It has the disadvantages of high price, large amount of corrosion inhibitor, and high conductivity when used in computer cooling.

Invention patent ZL201110333874.5 has been further improved on the basis of it. The improved cooling liquid consists of: 1000 parts of ethylene glycol, 0.4-4 parts of azelaic acid, 0.4-4 parts of phthalic acid, 0.1-2 parts of benzotriazole 0.1-3 parts of octanoic acid, 0.2-2 parts of glutaric acid, 0.1-0.09 parts of defoamer and 500-2000 parts of deionized water. Generally speaking, it is more practical for computer cooling, but it still cannot be separated from engine coolant And the category of deionized water cooling
