The material is characterized in comprising dibenzyl toluene, methyl hydroxy silicone oil, octodecamino propylamine, terminated polyisobutylene, and nano-grade nickel-chromium alloy micro-particles. The heat transfer fluid novel material provided by the invention has high heat transfer efficiency and high heat dissipation speed, and is mainly used in a solar energy CSP solar thermal power generation system. The nano-grade nickel-chromium alloy micro-particles are adopted as a dispersed phase in the heat transfer fluid novel material. The product provided by the invention has a heat conductivity coefficient of 1.65W/m.K-2.65W/m.K, which is 10 times that of prior arts. The heat dissipation speed of the product is greatly higher than that of similar products in prior arts. That is also the core value of the invention.
Description
Technical field
The present invention relates to a kind of high-efficiency thermal conductive liquid for sun power CSP solar-thermal generating system, be specifically related to include the heat transfer oil novel material that nano level nichrome particulate is 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 sun power CSP solar-thermal generating system and include the heat transfer oil novel material that nano level nichrome particulate is disperse phase, to solve prior art Problems existing.
For achieving the above object, the technical solution adopted in the present invention is the heat transfer oil novel material including nano level nichrome particulate, and the feature of its formula is: be made up of dibenzyl toluene, methylhydroxy silicone oil, 18 amino propylamine, end group polyisobutene, nano level nichrome particulate.
The weight percent of its each component of filling a prescription is:
Described dibenzyl toluene and methylhydroxy 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, nano level nichrome particulate is as the conductive particles of disperse phase, the diameter of particulate is below 2.5 microns, and distributive law is more than 92%.
The described heat transfer oil novel material including nano level nichrome particulate, 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 nano level nichrome 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 1.65W/mK ~ 2.65W/mK, more than 10 times of prior art, its heat radiation speed far faster than prior art, this just the present invention include the core value place of nano level nichrome particulate heat transfer oil novel material.
Embodiment
The following examples make further proof to the present invention, the present invention is not limited thereto.
Embodiment one
Include the heat transfer oil novel material of nano level nichrome particulate, its component and weight percent as follows:
The present invention includes the heat transfer oil novel material of nano level nichrome particulate, its preparation method is: get 62 grams of dibenzyl toluene, 26 grams of methylhydroxy silicone oil, 2 gram of 18 amino propylamine, 2 grams of end group polyisobutene add respectively in a reactor and stir 20 minutes, after stirring, add 8 grams of nano level nichrome particulates again and continue stirring 15 minutes, then 100 grams of uniform work in-process are taken out, put into again in the ultrasonic emulsator of a 180W " cavitation " of doing 25 minutes, just obtain the good gray translucent of mobility or opaque liquid, this liquid is exactly finished product of the present invention.
Embodiment two
