对汽车钎焊铝热交换器的传热和压降特性进行了广泛的试验。在诱导开放式风洞中，对18个不同几何参数（包括管宽、百叶窗长度、百叶窗间距、翅片高度和翅片间距）的百叶窗翅片换热器样品进行了测试。结果显示为摩擦系数和科尔伯恩j系数与雷诺数的关系图，基于200至1600范围内的体积水力直径。报告了Sahnoun和Webb模型与当前测试数据之间的比较，发现了良好的一致性。 通过引入翅片因子，得到了科尔伯恩j因子的简单关联式。Colburn j系数的传热数据关联度在10%以内，摩擦系数的传热数据关联度在15%以内。关键词:热流、汽车、钎焊、铝、热交换器、实验、百叶窗、翅片管热交换器、几何形状、测试、风洞、摩擦系数、雷诺数、比较引文:研讨会、ASHRAE Trans。1994年，第100卷，第2部分

Extensive experiments on the heat transfer and pressure-drop characteristics of automotive brazed aluminium heat exchangers were carried out. 18 samples of louvred-fin heat exchangers with different geometrical parameters, including tube width, louvre length, louvre pitch, fin height, and fin pitch, were tested in an induced open wind tunnel. Results are presented as plots of friction factor and Colburn j-factor against Reynolds number based on the volumetric hydraulic diameter in the range of 200 to 1,600. The comparisons between the Sahnoun and Webb model and the present test data are reported and good agreement was found. By introducing a finning factor, a simpler correlation of the Colbourn j-factor is obtained. The heat transfer data for the Colburn j-factor are correlated within 10%, and those for the friction factor are within 15%.KEYWORDS: heat flow, motor cars, brazing, aluminium, heat exchangers, experiment, louvres, finned tube heat exchangers, geometry, testing, wind tunnels, friction factor, Reynolds numbers, comparing
