摘　　要：在对R134a在水平直齿外翅片管表面冷凝传热理论研究的基础上,利用用计算机建立了传热数学模型,并在实验室中用5根紫铜外翅片铜管进行试验验证,结果表明该理论数学模型在一定范围内的预测值是准确的。Based on the theoretical research on R134 condensation heat transfer behavior on the out surface of the horizontal outer-finned tube, the heat transfer mathematical model was built. With the help of relevant experimental analysis, it proves that the forecast value deduced from the model was accurate in a specific range.
