摘　　要： 对采用铝翅片扩展表面与弓形折流板支撑结构相结合的新型叠片式油冷却器和采用螺纹强化管的螺旋折流板油冷却器分别进行实验测试研究。结果表明,叠片式油冷却器具有更优良的综合性能;在中、小油流量时,其热交换量大、壳程压降较小,单位压降下的换热量要比螺旋折流板油冷却器约高50%,结构的紧凑性能够较好地满足设备小型及高效的发展趋势。 The experimental validation is used to study the heat transfer performance of two kinds of high-efficiency oil cooler. A fin tube type oil cooler with aluminum fin tubes supported by segmental baffles and an oil cooler with spiral tubes supported by helical baffles are explored in the research respectively. The test results show that the fin tube type oil cooler get a better comprehensive performance. The heat flow rate of fin tube type oil cooler is larger and the pressure drop through the shell pass is smaller than the values of the helical baffle oil cooler under the same condition of low to moderate oil flow rate. The heat transfer capacity of unit pressure drop in the fin tube type oil cooler is 1.5 times as that of the helical baffle oil cooler. Furthermore, the compact structure of the fin tube type oil cooler is good enough to meet the development trend of miniaturization equipment and high efficiency.
