Abstract

The invention discloses a novel heat transfer fluid material containing nanoscale pure-copper microparticles and belongs to the field of energy chemistry. The novel heat transfer fluid material is characterized by comprising benzyl toluene, methyl hydroxy silicone oil, octadecanaminopropylamine, terminated polyisobutylene and the nanoscale pure-copper microparticles. The invention aims at providing the novel heat transfer fluid material using the nanoscale pure-copper microparticles as dispersed phases, which has the advantages of high heat transfer efficiency and high heat-dissipation speed and is mainly used in a solar CSP optothermal power generation system. The thermal conductivity of the product is between 1.6W / m.K and 2.6W / m.K and is more than 10 times of that in the prior art; the heat-dissipation speed is far higher than that of the similar products in the prior art, which is the core value of 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 pure copper particles as a dispersed phase, and 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 transfer...
