7毫米（0.276英寸）板翅管换热器传热和摩擦特性的实验研究导管被取出。在本研究中，对8个商用板翅管换热器样品进行了测试。试验结果表明，对于四排盘管，翅片间距的影响可以忽略不计，对于两排盘管，随着翅片间距的增加，传热性能有明显的降低。此外，随着翅片间距的减小，强化传热率降低。单位:双引证:研讨会，ASHRAE交易，1998年，第104卷，第2部分，多伦多

Experimental investigation of the heat transfer and friction characteristics of plate fin-and-tube heat exchangers having 7 mm (0.276 in.) tube was carried out. In the present study, eight samples of commercially available plate fin-and-tube heat exchangers were tested. The test results indicated that the effect of fin pitch is negligible for four-row coils, and there is a detectable decrease of heat transfer performance with increase of fin pitch for two-row coil. In addition, the heat transfer enhancement ratios decrease with decrease of fin pitch.Units: Dual
