Furthermore the performances of heat transfers including corrugate plate, tube and fin-tube were compared under the same conditions. The results show that when the air frontal velocity is between 2.45 and 4.1m/s, the overall heat-transfer coefficient of plate heat exchanger ranges from 100 to 160 W/m^2/ equal to one sixth of that of fin- tube cooler based on tube outside area, which is about 70% higher than that of tube cooler. The volumetric heat transfer capacity of plate cooler is 1.5 times as that of fin-tube cooler and 15 times as that of tube cooler. The heat transfer capacity of per unit power of plate cooler is 5.5 times as that of tube cooler and similar results for fin-tube cooler.

在相同工况下，比较了波纹板式、光管式和翅片管式空冷器的性能指标，结果表明：迎面风速在2.45~4.1m/s之间，波纹板式空冷器传热系数达到100~160W/平方公尺/℃；约比光管式提高70%，但只有以管束外表面为基准的翅片管式传热系数的六分之一；板式空冷器单位体积换热量约是翅片管式空冷器的1.5倍，是光管式的15倍；板式空冷器单位功耗换热量约是光管式空冷器的5.5倍，而翅片管式空冷器与光管式空冷器则相差不大。
