Example Embodiment
[0023] Figure 1 to Figure 3 Shown is a flat heat pipe 100 according to the first embodiment of the present invention. The flat heat pipe 100 is made by powder injection molding technology. The specific steps are as follows:
[0024] (1) A mold 10 is provided. The mold 10 has a first cavity 11 and six second cavities 13 located at the upper and middle part of the first cavity 11 and communicating with the first cavity 11 at equal intervals. The shape of the cavity formed by the first and second cavities 11 and 13 is equivalent to the shape of the flat heat pipe 100. It is understandable that the shape of the first cavity 11 and the second cavity 13 can be a rectangular parallelepiped, a cylinder or other geometric shapes, and in this embodiment, they are all rectangular parallelepiped shapes.
[0025] (2) Provide a two-color molding injection machine (not shown), this two-color molding injection machine has two independent directions of injection systems.
[0026] (3) Provide a fi...
