a heat exchanging pipe manufacturing apparatus for HRSG and a heat exchanging pipe

摘要

present invention the outer surface of the metal tube to heat transfer fins are closed burden and at the same time as the heat transfer fins welded on I, relates to a device for manufacturing a heat transfer tube, and the waste heat recovery heat exchanger plant to be done irregularly bent rearward, and the rotation support portion which rotates at a constant speed of the tube, one side of the strip-shaped section at a predetermined interval on the outside of the tube and the heat conductive fins wound helically so that the supply unit for continuous supply with the heat conductive fins, in the heat transfer tube production apparatus comprising a welded portion for fixing the welding heat conductive fins wound around a tube integrally with the heat conductive fins wound in a spiral in the tube welding is that at the same time as further comprising a heat conductive fin bent in a zigzag pattern to transform the heat conductive fins. ; In this way, the task of forming a fire in the heat conductive fins are bent so that the regular schedule and at the same time easily made electrothermal yirueojim the direction of movement of the fluid passing through between the fins are irregularly formed, and the residence time of the fluid is increased, by which will have the effect that can quickly produce a maximized heat transfer tube heat exchange efficiency.
