Design Description of Stainless Steel Inner Fin Tube:
The high-efficiency and energy-saving inner fin heat exchanger developed by Cangzhou Datang Steel Pipe Co., Ltd. has a heat transfer area of more than 7 times and a heat transfer film coefficient of more than 8 times compared with the same specification of light tubes; the first-class vacuum brazing technology makes the heat exchanger with large heat transfer area, high vibration resistance and high pressure resistance, and can greatly reduce the volume of the heat exchanger, which is particularly suitable for clean and low-viscosity heat exchange media.
