Experimental Study of Heat Transfer Intensification for a Water cooled Shell and tube Oil Cooler

通过实验研究 ,比较了螺旋隔板花瓣管油冷却器和螺旋隔板低肋管油冷却器的传热和压降性能 ,实验结果表明 ,螺旋隔板花瓣管油冷却器比螺旋隔板低肋管油冷却器的总传热系数提高 10 %以上 ,而压降却低 46

On the basis of an experimental study a comparison was made of the heat transfer and pressure drop performance of the following two types of oil cooler, the petal shaped finned tube cooler with helical baffles and low finned tube cooler with helical baffles. The results of the study show that the total heat transfer coefficient of the first named oil cooler is higher than that of the second named one by more than 10% with the pressure drop of the former about 46% lower than that of the latter.
