【摘要】 在高粘度流体下对新型的螺旋折流板换热器和普通的垂直折流板换热器进行了对比实验研究，并对实验数据进行了关联，得到了螺旋折流板换热器壳程对流传热系数的近似计算模型。实验结果表明，对高粘度油品，相同流量下单位压降的壳程对流传热系数，螺旋折流板约为普通折流板的１．５倍，显示螺旋折流板换热器不仅适用于低粘度流体，也可用于高粘度流体，具有广阔的开发应用前景。更多还原

【Abstract】 An comparative experimental investigation of the helical baffes heat exchanger and the natural heat exchenger has been finished for the high viscosity fluid. The approximate model of convection heat transfer coefficient as been reported according to the experimental results. The convection heat transfer coefficient in unit pressure drop of the helical baffles heat exchanger is 1.5 times of the natural heat exchanger for the high viscosity oil. This indicates that the helical baffles heat exchanger is suitable for not only the low viscosity fluid but also the high viscosity fluid. Thus it has a wide developing and appling prospect.更多还原
