Abstract

The invention provides novel new energy vehicle cooling liquid and a preparation method thereof, and relates to the technical field of cooling liquid. The novel new energy vehicle cooling liquid comprises the following raw materials in parts by weight: 30-40 parts of ultrapure water, 0.1-0.4 part of 1, 3-propylene glycol, 0.1-0.6 part of sodium chloride, 0.05-0.15 part of sucrose syrup, 1-4 parts of mixed particles and 0.02-0.06 part of an additive, and the specific preparation method comprises the following steps: S1, preparing the raw materials in proportion; s2, mixing and stirring 1, 3-propylene glycol, sucrose syrup and ultrapure water to obtain primary cooling liquid; s3, sequentially adding sodium chloride into the primary cooling liquid, and then mixing and stirring in an environment of 60-80 DEG C to obtain secondary cooling liquid; and S4, adding the mixed particles and an additive into the secondary cooling liquid, and mixing and stirring in an environment of 90-115 DEG C to complete the preparation of the cooling liquid. The new energy vehicle cooling liquid disclosed by the invention has excellent cooling efficiency, can realize rapid cooling, is small in viscosity change and good in stability after being used for a long time, and is good in overall environmental protection property.

Description

technical field [0001] The invention relates to the technical field of cooling liquid, in particular to a new type of new energy vehicle cooling liquid and a preparation method thereof. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new vehicle power units), and the integration of advanced technologies in vehicle power control and driving. New technology, new structure of the car. Among them, the most common new energy vehicle is pure electric vehicle. The power battery is the core power component of the new energy pure electric vehicle. The heat generated by the internal reaction during charging and discharging can easily cause the temperature of the battery to rise. The temperature uniformity between the battery and the battery module affects the performance and cycle life of the battery. Especially in the high power demand of the automobile or und...
