High Efficiency Spiral Coil-wound Heat Exchanger

       High efficiency Spiral Coil-wound heat exchanger has structure parts of shell, central cylinder, tube sheet, tube and gasket etc. The tubes is tightly wound on the central cylinder with a certain helix angle and pitch. Each layer of tubes was separated by flat pad and special-shaped pad to ensure horizontal and vertical spacing between tubes. It has advantages of compact structure, high voltage resistance, reliable seal and heat expansion offset, etc.The inner fluid flows in a spiral manner and shell fluid crosses laterally through the wounded tubes, with high heat exchange coefficient. Since the heat transfer component is circular tube, the differential pressure and temperature limitation requirements between different fluids are little when several fluid coexist in one coil-wound heat exchanger for heat transfer to reduce the operation difficulty and run safety.
