【摘要】 对圆形钢串叶散热器自然对流换热的规律进行了试验研究。通过对试验数据的分析整埋得到肋壁局部换热系数的分布和肋壁平均换热系数与结构尺寸之间的经验公式，并得到自然对流换热的准则方程。用多吕标数学规划的方法得出了钢串片散热器的最佳结构尺寸。更多还原

【Abstract】 The authors of this article have done some research work on natural con- vection heat transfer of a radiator of round steel series of slice. According to the disposal and analysis of the experimental data, the distribution of the local heat transfer coefficients(HTC) of the fin, the empirical formulas of the mean HTC and the structure size, as well as a dimesionless equation of free-convection heat transfer have been obtained. By means of the mcthod of multi-objective mathematical programming the optimal structure size of the radiator of round steel series of slice is obtained.更多还原
