HEAT EXCHANGING FIN

The utility model relates to a heat exchanging fin. The utility model relates to a component of the heat exchanging apparatus, particularly a Heat exchanging fin. The fin has the characteristic that the utility model is precast provided with a containing concave and the outline of the containing concave is the same with the coated pipe component; the containing concave is continuously coated on the pipe component. Adopting the fin on the heat exchanging pipe component can enhance the heating quantity in unit surface area of the pipe component, eliminate the surface condensation water film of the heat exchanging pipe component to achieve the purpose of improve heat efficiency and saving energy. The fin has simple structure and low cost and can be mechanically produced continuously.
