摘要：为缩短牵引车用冷却模块匹配选型时间，提出一种牵引车用冷却模块匹配计算方法。以某型号牵引车为计算原型，对由中冷器、散热器和风扇组成的牵引车用冷却模块进行匹配计算，并通过整车转毂热平衡试验检验计算方法的准确性。整车转毂热平衡试验结果表明：本文中提出的冷却模块匹配计算方法能成功预测冷却模块的冷却能力，整车实车试验与理论计算结果相符，计算方法能够为实际应用中改善冷却系统的性能提供指导，提升冷却模块的匹配效率。

Abstract:To shorten the time of tractor with cooling module matching selection, a tractor with cooling module matching calculation method is proposed. Based on a type tractor for calculating, the composed of cold, radiator and fan tractor with cooling module matching calculation, and the calculation are verified by the vehicle transfer hub heat balance test method the accuracy of the matching of the cooling module. The results of the heat balance test of the vehicle hub show that the cooling module matching calculation method proposed in this paper can successfully predict the cooling capacity of the cooling module, and the test results of the vehicle in real vehicle are consistent with the theoretical calculation results. The calculation method can provide guidance for improving the performance of the cooling system and improve the matching efficiency of the cooling module.
