Embodiment 1

[0008] Embodiment 1, the method for improving the cooling performance of cooling oil in this embodiment is to add submicron copper powder to the base cooling oil, and the mass ratio of the submicron copper powder to the base cooling oil is 2:100, of course, in specific implementation The mass ratio of the submicron copper powder to the base cooling oil can also be other values ​​within the range of 1-10:100, and the diameter of the submicron copper powder is 0.1-5.0 microns.

Embodiment 2

[0009] Embodiment 2, the method for improving the cooling performance of cooling oil in this embodiment is to add submicron copper powder to the base cooling oil, the mass ratio of the submicron copper powder to the base cooling oil is 6:100, and the submicron copper powder The diameter of the powder is 0.1-5.0 microns.

Embodiment 3

[0010] Embodiment 3, the method for improving the cooling performance of cooling oil in this embodiment is to add submicron copper powder to the base cooling oil, the mass ratio of the submicron copper powder to the base cooling oil is 8:100, and the submicron copper powder The diameter of the powder is 0.1-5.0 microns.

[0011] The cooling oil in the above-mentioned embodiments one to three can be prepared by the following method:

[0012] (1) Add sub-micron copper powder and deionized water to form a slurry with a concentration of 110-150g / L. After standing for 90-120 seconds, take the above slurry and separate and remove it by suspension separation and filtration and sieving. The large copper powder particles in the submicron copper powder make the particle size and diameter between 1.5 and 4.5 microns;

[0013] (2), adopt vacuum filtration method, repeatedly wash and separate the soluble salt in the slurry with deionized water, check until there is no sulfate ion with the...

Abstract

A disclosed method for improving cooling performance of cooling oil comprises adding submicron copper powder into base cooling oil, wherein the mass ratio of submicron copper powder to base cooling oil is 1-10:100, and the diameter of the submicron copper powder is 0.1-5.0 mu m. According to the method for improving cooling performance of cooling oil, by adding submicron copper powder into cooling oil, millions of particles of the submicron copper powder are uniformly dispersed in per liter of cooling oil, and copper possesses extremely high heat conduction coefficient (up to 377 W / m*K), therefore, when submicron copper powder is contacted with a high-temperature part, the submicron copper powder is capable of rapidly adsorbing heat, and thus the cooling performance of the cooling oil can be substantially improved.

Description

technical field [0001] The invention relates to the technical field of cooling, in particular to a method for improving the cooling performance of cooling oil. Background technique [0002] Cooling oil is widely used in mechanical processing and equipment cooling, such as cooling of engine block, machine tool processing tools, cooling of machined parts, etc., all need cooling oil. [0003] However, the thermal conductivity of the cooling oil in the prior art is low, generally 0.4 to 0.6w / (m·k), and only a small number of cooling oils with high thermal conductivity can reach a thermal conductivity above 1.0, so the cooling oil in the prior art The cooling performance of the oil cannot fully meet the needs of users, and needs to be greatly improved. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method for improving the cooling performance of cooling oil to solve the problem of poor thermal conductivity of existing co...
