Heat-conducting medium

Abstract

The invention discloses a heat-conducting medium, comprising the following components of, by weight, 65-90 parts of ethylene glycol or propylene glycol, 15-30 parts of water, 0.15-2.0 parts of sodium benzoate, 0.15-1.5 parts of methyl benzotriazole, 0.35-1.2 parts of sodium molybdate, 0.15-1.0 part of potassium hydroxide, 0.8-1.5 parts of methanol, 0.8-1.2 parts of silicone oil, 0.15-0.7 part of triethanolamine or diethanolamine or monoethanolamine and 0.55-1.5 parts of sodium nitrate or magnesium nitrate. The heat-conducting medium provided by the invention can increase heat efficiency of a boiler, reduce or eliminate corrosion of the heat-conducting medium to a boiler liner or a heat supply system and increase the heat efficiency by 7-10%, without producing precipitates such as water scale and the like. The heat-conducting medium can prevent phenomenon of frozen cracks of equipment when heat is supplied in winter. Besides, the heat-conducting medium provided by the invention is not volatile and is a semi-permanent liquid that can be used for a long time after one time injection.

Description

technical field [0001] The invention relates to the field of heat conduction, in particular to a heat conduction medium. Background technique [0002] At present, in the operation of the boiler system, the heat transfer medium used is ordinary tap water or demineralized water. This liquid is easy to corrode the pipeline system and produce scale and other deposits. The thermal efficiency is low. With the extension of use time, the pipeline system will be corroded and damaged. Seriously, scale and other deposits become thicker and harder to remove, making thermal efficiency lower and lower, resulting in a huge waste of energy, especially when corrosion damage or scale and other deposits are too much to block the pipeline, and people fail to timely In the case of discovery, the pipes are prone to freezing and cracking, resulting in economic losses. In addition, ordinary tap water or demineralized water has poor thermal conductivity, and has a low boiling point and is volatile, ...

Problems solved by technology

[0003] The patent name is a boiler water supply compound, and the invention patent with the patent number of 200480011444.X discloses a boiler water supply compound, which solves the problem of heat conduction and the corrosion of boiler internal combustion devices and pipes to a certain extent. There are still defects in the use of the boiler water supply compound, that is, there are many plastic seals in the boiler and piping system. Using the heat transfer medium provided by the patent number 200480011444.X will cause corrosion of the plastic seals after long-term use, resulting in liquid leakage, etc. , affecting the normal use of the heating system
