Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to an ultra-thin plate type heat pipe and in particular to a thermal conductor with an ultra-thin flat wick structure.
  • 2. Description of Related Art
  • Since most current 3C electronic products indicate a trend towards a light, thin, short, and compact design, the heat pipes used therein for heat dissipation or heat conduction also need to be thinned down, which causes the creation of the ultra-thin plate type heat pipe (the thickness is below about 1.5 mm).
  • However, the thickness of the ultra-thin plate type heat pipe needs to be thinned, thus resulting in a thinner thickness of the wick structure therein, otherwise the steam channels with sufficient space cannot be formed in the heat pipe. During the manufacturing process, the excessively thin wick structure cannot be filled through the gap between the wall of the heat pipe and the mandrel. The reason is that a relatively small gap causes a greater resistance when the metal powder is filled and thus cannot be processed subsequently. Therefore, the powder wick structure in the previous ultra-thin plate type heat pipe is formed only in the local area in the heat pipe and not thinned. Consequently, the powder wick structure in the ultra-thin plate type heat pipe of the prior art cannot be easily filled into the cross section of the heat pipe completely, which cannot provide the adequate surfaces for evaporation and condensation and the truncated transfer surface. Also, this still does not have sufficient steam channels and solid internal support structures, resulting in easy collapse of the heat pipe and thus greater thermal contact resistance. Hence, the heat transfer efficiency cannot be improved further.
  • In view of this, the inventor pays special attention to research with the application of related theory and tries to overcome the above disadvantages. Finally, the inventor proposes the present invention which is a reasonable design and effectively overcomes the above disadvantages.
    • SUMMARY OF THE INVENTION

  • To achieve the above objective, the present invention provides a thermal conductor with an ultra-thin flat wick structure, comprising a hollow shell having a flat shape, and a wick structure disposed in the shell and contacted with an inner wall of the shell. The wick structure is a thin planar body having a plane and a pressing surface opposite to the plane. The plane is attached to the inner wall of the shell. A plurality of elongated concave surfaces are spacedly arranged on the pressing surface such that a steam channel is formed in the shell via each of the concave surfaces and an elongated wick structure connection is formed between each concave surface and the plane.
