摘　　要：建立了用于计算板管式冷凝器空气侧换热的数学模型,模型中考虑了背板的非等温特性,确定了背板表面传热系数的计算公式,并讨论了影响空气侧换热的因素。另外还通过板管式冷凝器的换热实验验证了模型的可靠性。A simulation model is developed to calculate the heat transfer on air side of tubeplate condenser and the heat convection coefficients for the outer plate are compared in the model including the non-isothermal characteristics. The results of heat transfer are compared with the experimental ones, which shows that the model and the calculation method are practical.
