Abstract
The utility model discloses a threaded fin heat exchange pipe which comprises a base tube, wherein a plurality of first light tube regions used for connecting a baffle plate are arranged on the outer wall of the middle part of the base tube, threaded fins are arranged on the outer wall of the middle part of the base tube and outside the light tube regions, and second light tube regions used for connecting a heat exchanger pipe plate is arranged on the outer walls at the two ends of the base tube. According to the utility model, the threaded fins are arranged, so that the heat exchange area of a single heat exchange pipe is effectively increased, when the shell side medium flows through the surface of the heat exchange pipe, the threaded fins play a cutting effect to a edge layer of layer flow, the thickness of a boundary layer is thinned, the turbulent flow formed on the surface is stronger than that of a light tube, further the boundary layer thickness is thinned, and a higher heat exchange effect is achieved; the threaded fins are arranged in lower positions, so as to be convenient for pipe penetration, meanwhile the fluid passing resisting force can be reduced, the pressure drop is lowered, and the required power is reduced; and the first light tube regions and the second light tube regions are arranged, so that the connection among the fin tubes, the heat exchanger pipe plate and the baffle plate are reliable, and the mounting is convenient.
