摘　　要：传统换热器强化传热研究往往只针对换热系数单一指标进行,较少考虑换热过程中流动阻力的损失。采用响应面分析法以换热系数及流动阻力作为双重目标函数,探讨鼓泡板式换热器中板片深度、角度、鼓泡个数、流速等多变量作用下鼓泡板式换热器的结构优化。结果表明:鼓泡倾角为46°、高度为5 mm、鼓泡个数为3个、流速为0.2 m·s^(-1)时,相对于初始结构摩擦系数下降56.65%,但是努塞尔数降仅降低20.34%。Traditional researches on enhanced heat transfer of heat exchanger are often carried out only for a single index of heat transfer coefficient, and less consideration is given to the loss of flow resistance during the heat transfer process. Using response surface analysis method and taking heat transfer coefficient and flow resistance as the dual objective function, the structure optimization of the bubble plate heat exchanger under the action of multiple variables including the plate depth, angle, number of bubbles and flow rate was explored. The results showed that when the bubbling angle was 46°, the height was 5 mm, the number of bubbling was 3, and the flow rate was 0.2 m·s^(-1), the friction coefficient was reduced by 56.65% from the initial value, but the Nusselt number was reduced by 20.34%.
