Abstract

The invention provides a cooling liquid for a wind power generator set, and a preparation method thereof, wherein the cooling liquid comprises, by weight, 25-95% of ethylene glycol, 0.2-4% of aliphatic monocarboxylic acid, 0.1-2% of an azole-based compound, 0.01-1% of a composite corrosion inhibitor, 0.001-0.3% of a defoamer, and the balance of deionized water. According to the present invention,the wind power cooling liquid adopts the synergetic effect of the azole-based compound, the composite corrosion inhibitor and the low-content aliphatic monocarboxylic acid, does not contain the inorganic salt, has advantages of excellent metal anticorrosive effect and extremely low electrical conductivity, and can meet the requirements of wind power generator set cooling systems on cooling, corrosion resistance, insulation, long-acting and the like of cooling liquids.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a cooling liquid used for a wind power generating set and a preparation method thereof. Background technique [0002] Wind energy is an inexhaustible green renewable energy. Worldwide, wind power is developing rapidly and continuously. During the operation of wind turbines, components such as gearboxes, generators, and control systems will generate a lot of heat. In order to ensure long-term stable and safe operation of the generator set, effective cooling of the above components is required. With the gradual increase of the single-unit capacity of wind turbines, for medium and large wind turbines, it is necessary to use circulating liquid cooling to meet the cooling requirements. [0003] Traditional coolants in the prior art mostly use inorganic salt formulations or organic / inorganic hybrid formulations, which have extremely high electrical conductivity, usually a...
