选取了发动机机油冷却器的4个主要厂家生产的同一型号的8个板翅式机油冷却器进行了传热和阻力特性的实验研究.结果表明,由于生产工艺的不同,机油冷却器的传热性能和阻力特性有较大的差异.根据机油冷却器传热性能和阻力特性的实验数据拟合了换热量、阻力、传热系数随机油流速的变化关系,可为机油冷却器的结构设计及选型提供依据.
The experimental results of heat transfer and resistance characteristics of the 8 plate-fin oil coolers of the same type produced by 4 major manufacturers of engine oil cooler were taken.The results show that due to the different production process, the heat transfer of oil cooler Performance and resistance characteristics are quite different.According to the experimental data of the heat transfer performance and the resistance characteristics of the oil cooler, the relationship between the heat transfer coefficient, the resistance and the heat transfer coefficient of the random oil flow rate is fitted, and the structure design of the oil cooler And selection based on.
