铝翼散热管式中冷器的设计计算方法

介绍了铝翼散热管式中冷器的特点，导出了该种形式的中冷器冷却元件几何参数的计算公式；对管外流体侧的通道当量直径计算、对流换热和流通阻力准则方程的建立提出了一种新的方法，总结出一套完整的中冷器设计和校核的计算步骤，并对12V190B柴油机中冷器进行了设计计算和试验。由计算和试验结果对比可知，增压空气进、出口温差的计算误差在6％以内，进、出口压力损失的计算误差在10％以内，说明该计算方法可以满足铝翼散热管式中冷器的设计使用要求。

Design and Calculation of Intercooler with Aluminum Radiating Fins

The paper introduces characteristics of the intercooler with aluminum radiating fins lists the formulas to calculate the geometry parameters of the radiator and raises a method to calculate equivalent diameter of the channel outsides fins, forms a equation of convection and heat exchanging and flowing resistance, and reveals the processes to design intercooler. The results show that the calculating error of temperature difference is less than 6%, and the calculating error of flow resistance is below 10%. The method can meet the requirement of designing intercooler.
