| 摘 要： | 通过实验及计算得到散热器传热系数的实验值及理论值,对平片型平直翅片管散热器、螺旋形翅片圆管散热器与整体式梳状翅片管散热器在同一工况下的散热性能进行了比较.通过实验导出平片型平直翅片管散热器和整体式梳状翅片管散热器的气侧传热因子二次拟合式.由二次拟合式计算出的2种散热器的传热系数与理论计算系数相比误差较小.

| Abstract: | Experimental value and theoretical value of heat transfer parameter of the heat transfer have been acquired by experiments and calculation.An experiment has been made among three diesel engines,that is,a flat plate-finned tube radiator,a helical round-finned tube radiator and an integral comb-finned tube radiator to compare their heat transfer factors under one operating mode.Compared with theoretical value,experimental value of heat transfer parameter of 2 heat transfers is smaller,and the experimental val... |
