Problems solved by technology

At present, the heat dissipation working fluid for phase change radiators is mainly water. Compared with other working fluids, water has the advantages of relatively large specific heat capacity, non-toxic and harmless, and strong compatibility. However, under high heat flux conditions (such as When LED lamps dissipate heat), the heat dissipation efficiency is limited. At the same time, under cold conditions, water is prone to volume expansion due to freezing, resulting in cracking of the phase change radiator
In order to improve the apparent specific heat of the cooling medium, organic solid-liquid phase change materials are usually dispersed in the base liquid

Abstract

The invention relates to a heat dissipating working medium of a radiator and a preparation method thereof. The heat dissipating working medium is prepared from, by weight, 5 to 9 parts of n-octadecane, 3 to 5 parts of glycerol, 6 to 8 parts of triazole toluene , 1 to 3 parts of ethyl acetate, 5 to 9 parts of phenoxyethanol, 2 to 5 parts of diethanolamine, 3 to 5 parts of acetone, 1 to 3 parts of methanol, 3 to 5 parts of isopropyl alcohol and 20 to 30 parts of distilled water. The heating dissipating working medium has the advantages that the specific heat capacity is high, the heat transfer effect is better, and the solidification is not easy under the low temperature environment, and the working condition is relatively stable.

Description

technical field [0001] The invention relates to the field of heat dissipation, in particular to a heat dissipation working fluid of a radiator and a preparation method thereof. Background technique [0002] Radiator is a relatively common heat dissipation device, which is mainly used to absorb heat from heating equipment and dissipate heat in the form of heat transfer. Phase change radiators are widely used, especially in the field of lighting. The working principle of the phase change radiator is to use the heat dissipation working fluid to take away a large amount of heat when it flows, so as to achieve the effect of cooling and heat dissipation. At present, the heat dissipation working fluid for phase change radiators is mainly water. Compared with other working fluids, water has the advantages of relatively large specific heat capacity, non-toxic and harmless, and strong compatibility. However, under high heat flux conditions (such as When LED lamps dissipate heat), th...
