Abstract

The invention discloses a heat transfer fluid new material internally containing titanium nickel alloy nanoparticles, belonging to the field of energy chemistry. The formula of the new material is characterized by comprising hydrogenated terphenyl, methyl silicone oil, octadecyl amino propylamine, diethyl ethanolamine, and titanium nickel alloy nanoparticles. The invention is to provide the heat transfer fluid new material internally containing titanium nickel alloy nanoparticles as a dispersion phase. The new material is high in heat transfer efficiency and fast in heat dissipation and mainly applied in a solar CSP solar-thermal power generation system. The product has a thermal conductivity coefficient of 1.25-2.35 W/m.K which is about ten times of that of products in the prior art, and the heat dissipation is faster than that of similar products in the prior art.

Description

technical field [0001] The invention relates to a high-efficiency heat transfer liquid used in a solar CSP photothermal power generation system, in particular to a new heat transfer liquid material containing nano-scale titanium-nickel alloy particles as a dispersed phase. The invention belongs to the field of energy chemistry. Background technique [0002] At present, the heat transfer medium used in mature and commercial trough solar CSP photothermal power generation systems is heat transfer fluid, which is divided into mineral type and synthetic type. Mineral type heat transfer fluid is called mineral heat transfer oil, and synthetic type heat transfer fluid The liquid is called synthetic heat transfer oil. Mineral heat transfer oil is obtained by extracting a certain fraction during petroleum processing, refining it, and then adding various additives. It is easy to solidify at low temperature, easy to oxidize at high temperature, and has a short service life; synthetic h...
