This utility model discloses a dual-purpose (dry and wet) heat exchange tube, belonging to the field of heat exchange technology. It includes a flat heat exchange tube with straight-through S-shaped fins connected to it. A partition plate is fixed inside the flat heat exchange tube, and a baffle plate is installed inside the tube. A connecting assembly is installed at the end of the tube, and a support and protective structure is snapped onto it. Using a flat heat exchange tube in conjunction with straight-through S-shaped fins achieves both dry and wet application, reducing equipment size.
