Problems solved by technology

As mentioned before, although the specific heat capacity of water is large, its thermal conductivity is not very good, and it corrodes the metal parts of electronic equipment. Therefore, it is often unable to meet the heat exchange requirements of electronic equipment with increasing power density.

Embodiment 1

[0023] Embodiment 1 provides a kind of heat transfer fluid, and it is made up of the raw material of following weight ratio:

[0024] 2 parts of coupling agent, 0.1 part of cobalt oxide, 5 parts of emulsifier, 0.1 part of heterocyclic compound, 50 parts of deionized water, and 50 parts of ethylene glycol.

[0025] Among them, the coupling agent is tetraethylene glycol, polyethylene glycol 100 and polypropylene glycol 400 three kinds of additives compounded at 8:1:1. The emulsifier is lauryl glutamate, lauryl methionine, and lauryl arachidic acid at a ratio of 1:1:1. The heterocyclic compound is 5-butylbenzotriazole and 1H-benzotriazole- 1-methanol was used in a 2:1 compounding ratio.

[0026] The heat transfer fluid of this embodiment is prepared by the following method: 0.1 parts of cobalt oxide nanoparticles are weighed with an electronic balance with a resolution of 0.1 mg. Then add 5 parts of emulsifier to 50 parts of deionized water and 50 parts of ethylene glycol and s...

Embodiment 2

[0028] Embodiment 2 provides a heat transfer fluid, which differs from Embodiment 1 only in that: the coupling agent is polyethylene glycol 100, and the emulsifier is lauryl glutamate.

Abstract

The invention relates to the technical field of heat transfer fluids, in particular to a heat transfer fluid and a preparation method and application thereof. The heat transfer fluid comprises the following components in parts by weight: 40-60 parts of water, 40-60 parts of ethylene glycol, 2-8 parts of an emulsifier, 1-3 parts of a coupling agent, 0.05-0.2 part of cobalt oxide and 0.05-0.2 part of a heterocyclic compound. Compared with a traditional water-ethylene glycol heat conduction liquid, the heat conduction coefficient of the heat transfer fluid is increased by 15%, the heat transfer strength in the aspect of a cooling system is enhanced by 60%, the area of a radiator is reduced by 26%, and the performance is remarkably improved. The additive in the heat transfer fluid has high performance of dispersing stable nanoparticles and does not affect the corrosion inhibition performance of metal, and meanwhile the heterocyclic corrosion inhibitor has excellent corrosion inhibition performance.

Description

technical field [0001] The invention relates to the technical field of heat transfer fluid, in particular to a heat transfer fluid and its preparation method and application. Background technique [0002] In the field of heat dissipation of electronic and electrical equipment, liquid cooling technology has long been accepted by equipment manufacturers. As a mature heat dissipation technology, liquid cooling has been widely used in the cooling of electronic equipment, especially components with high power density such as power semiconductors, CPU / GPU and ASIC chips. The coolant used in liquid cooling is mainly water-based and oil-based. The advantage of water-based over oil-based is that the heat dissipation medium has a large specific heat capacity, does not burn, and is cheap. Therefore, more and more electronic devices now use water-based Coolant. As mentioned before, although water has a large specific heat capacity, its thermal conductivity is not very good, and it cor...
