The result shows that heat transfer coefficient of corrugated tube heat exchanger is over 1.5 times than that of bare tube.
结果表明，波纹管换热器的总传热系数比光管高1.5倍以上。
The results show that this new structure may raise the heat transfer coefficient up to the range of 40% to 100% in comparison with bare tube one; meanwhile, higher flow resistance is also existed.
结果显示螺旋折流片诱导的涡旋流动对于减薄边界层，促进近壁流体与主流区流体的动量和质量交换进而强化传热有明显的作用，传热系数可比光管提高约40％-100％，但其流动阻力也将增大。
