介绍了油-水强化换热用整体外肋管和水-水强化换热用整体内、外翅片管的单管筛选试验情况,给出了传热和阻力测试结果,并给出了回归的传热系数关联式。试验结果表明,外肋管的总传热系数比光管提高约15%,内、外翅片管比光管提高约50%
This paper introduces the single-tube screening test of integral external and external finned tubes for oil-water intensified heat exchange with integral external fin tubes and water-water intensified heat exchange. The heat transfer and resistance test results are given and the regression The heat transfer coefficient correlation. The test results show that the total heat transfer coefficient of the outer rib tube is about 15% higher than that of the light pipe, and the inner and outer fin tubes are increased by about 50%
