Description
Technical field
The present invention relates to a kind of high-efficiency thermal conductive liquid for sun power CSP solar-thermal generating system, the heat transfer oil novel material that to be specifically related to nanosized copper zinc alloy particulate be disperse phase, the invention belongs to field of energy chemistry.
Background technology
At present, ripe and the heat transmission medium that business-like groove type solar CSP solar-thermal generating system uses is heat transfer oil, it is divided into mineral type and synthesis type two kinds, and the heat transfer oil of mineral type is called mineral thermal conduction oil, and the heat transfer oil of synthesis type is called synthesis type thermal conduction oil.Mineral type thermal conduction oil is in petroleum refining process, extracts certain section of cut, and through refining, then add that multiple additives produces, its low temperature easily solidifies, and high temperature is oxidizable, and work-ing life is not long; Synthesis type thermal conduction oil is pure or purer chemical, has Heat stability is good, use temperature is high, the life-span is long and the feature such as renewable; No matter the heat transfer oil of mineral type, or the heat transfer oil of synthesis type, all there is heat transfer efficiency low, slow problem of dispelling the heat.
Summary of the invention
The object of the invention is: for above-mentioned deficiency, there is provided that a kind of heat transfer efficiency is high, rapid heat dissipation, be mainly used in the heat transfer oil novel material that nanosized copper zinc alloy particulate is disperse phase in sun power CSP solar-thermal generating system, to solve prior art Problems existing.
For achieving the above object, the technical solution adopted in the present invention is a kind of nanosized copper zinc alloy particulate heat transfer oil novel material, and the feature of its formula is: be made up of biphenyl-biphenyl ether, methyl-silicone oil, 18 amino propylamine, end group polyisobutene, nanosized copper zinc alloy particulate.
The weight percent of its component is:
Described biphenyl-biphenyl ether and methyl-silicone oil in the middle of the present invention as the external phase carrier fluid of temperature tolerance, oxidation resistant, 18 amino propylamine and end group polyisobutene are as hyper-dispersant, nanosized copper zinc alloy particulate is as the conductive particles of disperse phase, the diameter of particulate is below 1.5 microns, and distributive law is more than 92%.
Described a kind of nanosized copper zinc alloy particulate heat transfer oil novel material, the use temperature of its best is 400 degrees Celsius.
The present invention compared with the existing technology has the following advantages and positively effect: first, and its thermal conductivity of the thermal oil of prior art, usually between 0.12W/mK ~ 0.19W/mK, exists heat radiation slow, the problem that heat transfer efficiency is low.The present invention is through secondary reality examination up to a hundred and after improving, the nanosized copper zinc alloy particulate adopting heat transfer efficiency high is conductive particles, and, it is made to be highly dispersed in carrier fluid, its thermal conductivity of product of the present invention is between 1.3W/mK ~ 2.4W/mK, about 10 times of prior art, speed of its heat radiation far faster than prior art, the core value place of this kind of nanosized copper zinc alloy of the present invention particulate heat transfer oil novel material just.
