对于大型电子设备的液冷散热系统,为实现冷却介质的传输,需敷设复杂的液冷管路网络,如何合理实现各管路的流量分配,直接关系到设备的安全可靠性及经济性。针对多分支复杂液冷管路网络的流量分配问题,提出一种理论计算与仿真分析相结合的设计方法。以某等分流量液冷管路网络为例,经过理论计算、仿真分析、流阻优化和试验测试,设计的流量分配的准确度高于94%,对工程应用中类似系统的流量分配设计具有一定的借鉴意义。

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.
