A net chain driving structure includes a conveying net chain. The conveying net chain includes a plurality of chain links successively inserted in a conveying direction, a plurality of lugs spaced apart from each other are arranged on two sides of the chain links, an end portion of the lug is an arcuate face, a meshing groove is disposed on the chain link, the meshing groove is spliced by an open slot provided on a back side of the chain link and the lugs on the adjacent chain links, a gear in transmission meshing with the meshing groove is disposed on each end of the conveying net chain, a tangent plane tangential to the arcuate face is disposed on the arcuate face of the lug, and transmission contact toothed surfaces of the tangent plane and the gear are attached to each other in parallel during meshing transmission.

The present invention relates to a streamlined wavy fin for a finned tube heat exchanger, which comprises a fin body, an airflow inlet on one end of the fin body, an airflow outlet on the other end of the fin body, mounting holes for mounting tubes on the fin body, and several convex/concave ripples consecutively formed from the airflow inlet to the airflow outlet on the fin body in an orientation of an airflow streamlines. A connection line of the wave crests of the same one convex ripple and a connection line of the wave troughs of the same one concave ripple neighboring the same one convex ripple are both streamlines. The present invention efficiently suppresses the flow separation downstream the circular tubes, and obviously reduces the pressure loss of airflow. And at the same time, the surface areas of the fins are increased, heat transfer resistance on the fin side is decreased, the streamlined fluid flow makes that it is not easy to producing a recirculation flow downstream the circular tubes, and heat transfer performance of the fins at the rear part of the tube bank may be obviously improved, which has better fluid flow and heat transfer performances, the fins is not easy to accumulate dust in use, and stability of heat transfer performance is maintained.
