摘　　要：基于对现有混水器换热结构的数值研究,分析造成其出口温度波动大、压力损失高的原因,并在此基础上提出高效混水结构形式。数值研究结果显示:新型换热结构出口温度波动在±1℃以内,而系统压损没有显著降低。在考虑结构工艺性的同时,结合优化算法,提出一种多排短叶片混热方式,温度波动控制在±1.1℃,而压力损失降低超过50%。Based on the numerical study of the heat transfer structure of the existing water mixer,the reasons for the large temperature fluctuation at the outlet and the high pressure loss are analyzed.Then,an efficient water mixer structure is proposed.The numerical results show that the outlet temperature fluctuates of the new structure within±1℃,while the pressure loss of the system does not decrease significantly.Considering the structure process ability,and combined with the optimization algorithm,a multi-row short blade heat mixer structure is proposed.The temperature fluctuation is controlled within±1.1℃,and the pressure loss is reduced by more than 50%.
