  • In another prior art, a plurality of heat dissipating tubes are installed into the fins. This prior art is used to a compact space which is not suitable for installing with a fan.
  • In one prior art, the welding material is used to combine the heat dissipating tube to the wall of the via hole of the fin and then they are placed in a vacuum oven for heating so that welding material will permeate into the gaps between the heat dissipating tubes and the via holes. However the cost of the oven is high and time period is long so that the yield rate is low. Furthermore, the welding material will pollute the environment and harm human bodies.
  • With reference to FIG. 1, a prior art is illustrated. Each fin 10 has a plurality of via holes 12 and then the heat dissipating tubes 11 are placed into the via holes 12. Each time only one fin 10 is installed with the heat dissipating tubes 11. The fin 10 is punched so as to tighten the heat dissipating tubes 11 to the via holes 12. Then another fin is installed with the heat dissipating tubes 11 and the process is repeated.
  • However the punching process will generate gaps between the heat dissipating tubes 11 and the via holes 12, see FIG. 2. The yield ratio is low and the heat dissipation from the heat dissipating tube 11 to the fin 10 is affected. The punching process is performed one by one, and thus the punching process will destroy the fins and heat dissipating tubes.
  • Furthermore, in the punching process, oil is added between the heat dissipating tubes and the walls of the via holes. The oil will permeate into the combining surfaces so that the material of the heat dissipating tubes will oxidize to increase the heat resistance of the combining surface and the heat dissipation ability is reduced.
