摘　　要：为了探究高度对散热器散热量的影响,将中心距作为体现散热器高度的参数。对铜铝复合柱翼型散热器、钢铝复合柱翼型散热器、压铸铝散热器、钢制柱型散热器这几类散热器进行了试验研究,测试了它们在不同高度和温度条件下的散热量。根据所测量的数据,利用最小二乘法拟合计算得到关于散热量与高度和温差的两个函数关系。在标准工况下,将通过函数关系式计算得到的数据与实际测量数据进行比较分析,从中得到准确性更高的关系式。In order to explore the influence of height on radiator heat dissipation, the center distance as the embodiment of the height parameters of radiator. The copper-aluminum column-wing-type radiator, the steel-aluminum column-wing-type radiator, die-cast aluminum radiator and steel column radiator are tested in conditions of different height and temperature of heat dissipating capacity. The least squares fitting applied to gain two functions of heat dissipation and height, heat dissipation and temperature based on the measured datc~ Under stan- dard conditions, the calculated and actual measured data are compared and analyzed, obtaining the higher accuracy relation.
