在低粘度流体下对扰流子折流杆换热器和折流杆换热器进行了传热性能和阻力性能的对比实验研究。实验以水作为传热介质，热水走壳程，冷水走管程。实验时壳程流体流动状态基本恒定，而管程流体发生变化。通过实验数据的分析关联，得到了加入扰流子后管程对流传热系数的近似计算模型。结果表明，当雷诺数的范围为１０４ ～５ ×１０４ 时，管程对流传热系数增加的幅度高于阻力增加的幅度，管程对流传热系数和换热器总传热系数分别提高５０ ％ 和１０ ％ 以上。说明对水这样的低粘度流体，在传热湍流区（ 即雷诺数大于１０４ 的范围） ，可以采用较大节距的扰流子来强化传热，以取得较佳的综合效果。
A comparative experiment on the heat transfer performance and the resistance performance of the spoiler baffle rod heat exchanger and the baffle rod heat exchanger was carried out under the condition of low viscosity fluid. Experiment with water as a heat transfer medium, hot water shell, cold water tube. During the experiment, the fluid flow in the shell-side fluid was almost constant while the fluid in the tube-side fluid changed. Through the analysis and correlation of the experimental data, an approximate calculation model of the convective heat transfer coefficient of the tube after adding the turbulent flow was obtained. The results show that when the Reynolds number ranges from 104 to 5 × 104, the convective heat transfer coefficient of the pipe increases more than that of the resistance increase, and the convection heat transfer coefficient of the pipe and total heat transfer coefficient of the heat exchanger increase by 50% And 10% or more. It shows that for low viscosity fluid such as water, the larger pitch spoiler can be used to enhance the heat transfer in the heat transfer turbulence zone (ie, the range of Reynolds number is greater than 104), so as to achieve a better overall result.
