| 摘 要： | 光滑扭带具有自动清洗传热设备水垢的功能，但是在管内低流速下由于自转力矩太小而不能应用。为此研制一种能够显著增大自转力矩的强化型斜齿扭带。试验结果表明：在管内流速相同情况下，强化型斜齿扭带与结构参数相同的光滑扭带相比：自转力矩增大277％，传热系数提高22％，流体阻力保持在工程许可的范围内。因此，这种强化型斜齿扭带可以在低流速的列管式传热设备中广泛应用。

| Abstract: | It is the function of smooth twisted strips that cleans water fouling inhering to the inner wall of heat exchanging tube, but it cannot be used in the conditions of low flowing velocity because of too little rotational moment. So, the twisted strip with teeth is developed to enhance the moment notably. The test results show that the moment and heat transfer coefficient of the twisted strip with teeth are increased by 277% and 22% respectively ,compared with that of the smooth twisted strip without any teeth in the conditions of common flowing velocity. The flowing resistance is in the range of engineering permission. Therefore, the new kind of twisted strip with teeth can be used widely in shell tube heat exchangers of low flowing velocity. |
