小型高速风冷柴油机散热片传热性能研究

本文对散热片组给定了若干假设并以此为基础，对散热片组的传热现象进行详细的分析，找出了影响传热系数的各种因素；根据散热片换热过程的物理特征与实验结果，利用高斯多元线性回归方法，综合成适用于实验条件范围内的传热系数经验公式。结果对各种风冷柴油机在强制对流条件下的传热机理研究及强化传热技术应用有参考价值。

STUDIES ON HEAT TRANSFER CHARATERISTICS OF FIN ARRAYS FOR AN AIR-COOLED DIESEL ENGINE

Several assumptions have been given to the fin arrays in this paper and based on these the heat transfer phenonmon has been analysed in detail to find oat various factors affecting its heat hansfer coefficient At the same time, an experience equation of the coefficient has been built under the experimental conditions through synthesiaing the physical characteristics and experimental results in the course of heat transfer of the arrays by use of Gauss Multichannel Linear Regress. The results of the present research have good reference to the studies of heat transfer mechanism under forced convection for varieties of high speed air-cooled engines and appli canons of heat transfer enhanced technologies.
