Abstract

The invention discloses a novel nanometer-grade copper-iron alloy micro-particle heat conducting liquid material and belongs to the field of energy chemistry. The prescription of the novel nanometer-grade copper-iron alloy micro-particle heat conducting liquid material is characterized by consisting of hydrogenated terphenyl, chloridized silicon oil, octadecylamino-propylamine, diethylethanolamine and nanometer-grade copper-iron alloy micro-particles. The invention aims to provide a novel heat conducting liquid material which is high in heat conduction efficiency, rapid in cooling and mainly applied to a solar CSP photo-thermal power generation system and takes nanometer-grade copper-iron alloy micro-particles as a dispersion phase. The novel nanometer-grade copper-iron alloy micro-particle heat conducting liquid material disclosed by the invention is 1.2W/m.K to 2.3W/m.K in heat conduction coefficient which is about ten times that of the prior art and is far faster than the same type of products in the prior art in cooling speed, which is just the core value of the novel nanometer-grade copper-iron alloy micro-particle heat conducting liquid material disclosed by the invention.

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 with nano-scale copper-iron 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 heat transf...
