摘要：PURPOSE:To improve the capability of thermal transfer of a fin in itself and enable a substantial improvement of an air flow at a rear side of a pipe by a method wherein the spiral fin formed with a mesh forming part and a bending part is wound around a tube in a spiral form. CONSTITUTION:A heat exchanging tube is made such that a spiral fin 3 having a high thermal transfer characteristic formed with a mesh working part 5 having mesh work and a bending work part 6 are wound around and the mesh worked fin 3 is continuously wound around the tube 1. The tube is a passage for thermal medium so as to perform a heat exchanging operation between the fin and the thermal medium. The fin is to perform a heat exchanging operation, the fin is formed with meshes. When the fin is wound around the tube, the meshes are expanded at the outer most circumference of the fin and so it can be wound while the fin is connected. With this arrangement, it is possible to increase air resistance or air accumulation which are problem in the prior art slit fin and then to improve substantially a capability of heat exchanging operation.
