Carbon nanotube water-free cooling liquid

Abstract

The invention relates to a carbon nanotube water-free cooling liquid which comprises 0.5-10% of a carbon nano tube, 89.45-99% of propylene glycol and 0.05% of cetyl trimethyl ammonium bromide. According to the carbon nanotube water-free cooling liquid, due to the addition of the carbon nanotube, the heat conductivity coefficient is greatly improved, and at the same time the ice point can be -60 DEG C, the boiling point is as high as 180 DEG C, and the heat conductivity coefficient of the carbon nanotube water-free cooling liquid can be more than 0.468W / mK at 100 DEG C and is twice as much as the heat conductivity coefficient (0.234W / mK) of a propylene glycol basic liquid.

Description

technical field [0001] The invention relates to an anhydrous cooling liquid for carbon nanotubes. Background technique [0002] Coolant, also called antifreeze coolant, is a coolant with antifreeze function, which is well used in the normal maintenance of automobile engines. The traditional coolant is composed of water, antifreeze and additives, which have the functions of heat dissipation, antifreeze and anti-scaling. With the continuous development of technology, the coolant can be divided into several categories according to the composition; for example, ethanol is used as antifreeze, Its boiling point is low, it is easy to evaporate and lose, its freezing point is easy to rise, and it is flammable, so it has been gradually eliminated. Moreover, generally existing coolants have a relatively high water content and are used as engine refrigerants. They also have technical problems such as scale and corrosion, which brings inconvenience to the normal maintenance of automobi...

Problems solved by technology

The traditional coolant is composed of water, antifreeze and additives, which have the functions of heat dissipation, antifreeze and anti-scaling. With the continuous development of technology, the coolant can be divided into several categories according to the composition; for example, ethanol is used as antifreeze, Its boiling point is low, it is easy to lose by evaporation, its freezing point is easy to rise, and it is flammable, so it has been gradually eliminated.

Moreover, generally existing coolants have a relatively high water content and are used as engine refrigerants. There are also technical problems such as rust and corrosion, which brings inconvenience to the normal maintenance of automobile engines.
