1. A method for combining axially heated heat pipes and a heat-conducting base, comprising the steps of:

  • preparing a heat-conducting base with a bottom surface to be heated for adhering onto a heat source and a heat-dissipating surface opposite to the bottom surface, and a plurality of heat pipes each with an end to be heated and a condensed end opposite to the end to be heated;

    providing a plurality of penetrating holes on the heat-dissipating surface of the heat-conducting base, and inserting the end to be heated of each heat pipe into a corresponding penetrating hole of the heat-conducting base, an axial direction of the end to be heated of the heat pipe being substantially identical to that of the corresponding penetrating hole and substantially perpendicular to the heat-dissipating surface;

    performing a lateral pressing to the heat-conducting base so as to bring each heat pipe into a tight and planar contact with the wall of the corresponding penetrating hole in a direction of pressing; and

    grinding the bottom surface of the heat-conducting base to become a flat surface to make an end portion of the end to be heated of each heat pipe flush with the bottom surface of the heat-conducting base, so that the end portion of the end to be heated of each heat pipe is directly heated by the heat source,wherein the heat-dissipating surface is substantially a round surface and one of the penetrating holes is located at a center of the round surface and other penetrating holes are arranged at different circles with the same center of the round surface.
