传热系数换热操作中热量通量 q（见传热过程）与传热推动力（温度差Δt）的比例系数，即： K＝q/Δt它在数值上等于在单位温度差推动下于单位时间内经单位传热面所传递的热量，它与传热面积乘积的倒数为传热过程的总热阻。对于通过平壁的传热，K可表述为：式中 α1和 α2分别为壁面两侧的传热分系数;λ和δ分别为间壁的热导率和厚度;R1和R2分别为表征壁面两侧的垢层热阻的系数。当传热过程的温度差一定时，传热系数越大，则换热器的传热速率越高。虽然减小任何一项热阻都可提高传热系数，但当某项热阻远高于其他项时，传热系数将主要取决于此控制项的热阻。壁面热阻通常很小，可忽略不计。垢层可产生相当大的热阻，因之换热器的传热面需定期清洗。换热器设计时，控制项的热阻需准确地确定。在考虑强化传热过程时，首先设法减少控制项的热阻。传热系数的大小与冷热流体的性质、换热的操作条件（如流速、温度等）、传热面的结垢状况以及换热器的结构和尺寸等许多因素有关。对流传热十分复杂，垢层热阻又难以确定，因此传热系数的计算值与实际值往往相差较大。在设计换热器时，最好有实测值或生产中积累的经验数据作为参考。
