Embodiment 1

[0012] The new heat transfer fluid material containing nano-sized aluminum-silicon alloy particles, its composition and weight percentage are as follows:

[0013]

[0014] The new material of the heat conduction liquid containing nano-scale aluminum-silicon alloy particles in the present invention is prepared by: taking 62 grams of xylyl ether, 26 grams of methyl phenyl silicone oil, 2 grams of diethylethanolamine, and 2 grams of terminal polyisobutylene Put them into a reactor and stir for 25 minutes. After stirring evenly, add 8 grams of nano-sized aluminum silicon alloy particles and continue stirring for 15 minutes. Then take out 100 grams of uniform semi-finished products and put them into a 180W ultrasonic emulsifier for 25 minutes. Within minutes of "cavitation", an off-white translucent or opaque liquid with good fluidity is obtained, which is the finished product of the present invention.

Description

Technical field [0001] The invention relates to a high-efficiency heat conduction liquid used in a solar CSP photothermal power generation system, in particular to a new heat conduction liquid material containing nano-scale aluminum-silicon 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 the mature and commercialized trough solar CSP photothermal power generation system is heat transfer fluid, which is divided into two types: mineral type and synthetic type. The mineral type heat transfer fluid is called mineral heat transfer oil. The synthetic heat transfer medium The liquid is called synthetic heat transfer oil. Mineral heat transfer oil is made by extracting a certain fraction in the process of petroleum processing, after refining, and adding a variety of additives. It is easy to solidify at low temperature, easy to oxidize at high temperature, and has a sho...
