Method for controlling quality of cooling liquid

Abstract

The invention discloses a method for controlling the quality of cooling liquid. The method comprises the following steps of: extracting a certain amount of cooling liquid serving as a sample, wherein the cooling liquid is metal corrosion inhibitor-containing distilled water; detecting numerical values of parameters in the sample, wherein the parameters comprise at least one of a pH value, total hardness, a total bacterial count, metal ion concentration, halogen ion concentration and conductivity; and comparing the detected numerical values of the parameters with preset reference indexes, and when the numerical values of the parameters is out of the range of the reference indexes, replacing the cooling liquid. In the method, the cooling liquid in a liquid cooling system is detected, so that the running cooling liquid can be monitored in real time, the cooling liquid which does not meet the quality requirement is replaced, the quality of the cooling liquid and the cooling effect are guaranteed, scaling and corrosion trends of the cooling liquid are inhibited, and all pieces of equipment in the cooling system can be ensured to be normally used.

Description

technical field [0001] The invention relates to a quality control method of cooling liquid. Background technique [0002] With the application of VLSI, the processing power of computers is getting stronger and stronger, which leads to the increase of power consumption of computer chips. For example, the power consumption of existing large-scale computer devices can be increased to 160W, and the heat flux Can reach 100W / cm 2 . [0003] It is becoming more and more urgent to design an efficient cooling system to obtain greater cooling capacity. Liquid cooling system is a widely used cooling system. In order to solve the heat dissipation problem of high heat flux components, whether the design of liquid cooling system is reliable and advanced is directly related to the success or failure of the entire computer system. [0004] A common liquid cooling system is composed of coolant, pump, coolant unit, valves, pipes, cold plate (heat exchanger), etc. The coolant is driven by t...
