Research on Flow Distribution of Multi-branch Liquid Cooling Pipeline Network Based on Simulation

For the cooling system of large electronic equipment, in order to realize the transmission of cooling medium, it is necessary to lay a complex network of liquid cooling pipeline. How to reasonably realize the flow distribution for each pipeline is directly related to the safety, reliability and economy of the equipment. In order to solve the flow distribution problem of the multi-branch complex liquid-cooling pipeline network, this paper presents a design method of combining theoretical calculation and simulation analysis. Taking a liquid-cooling pipeline network with equal flow rates as an example, through theoretical calculation, simulation analysis, flow resistance optimization and test, the accuracy of the designed flow distribution is higher than 94%. The method has certain reference significance for the flow distribution design of similar systems in engineering applications.
