Abstract

A method for combining axially heated heat pipes and a heat-conducting base includes the steps of preparing a heat-conducting base and a plurality of heat pipes, providing a plurality of penetrating holes on a surface of the heat-conducting base, inserting one end of each heat pipe into the individual penetrating hole of the heat-conducting base, 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 each corresponding penetrating hole in the direction of pressing, and grinding the bottom surface of the heat-conducting base to become a flat surface to make the end of each heat pipe flush with the bottom surface of the heat-conducting base.

Claims

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

preparing a heat-conducting base and a plurality of heat pipes;

providing a plurality of penetrating holes on a surface of the heat-conducting base, and inserting one end of each heat pipe into a corresponding penetrating hole of the heat-conducting base;

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 each heat pipe flush with the bottom surface of the heat-conducting base.

2. The method for combining axially heated heat pipes and a heat-conducting base according to claim 1, wherein the heat-conducting base is made of aluminum or copper.

3. The method for combining axially heated heat pipes and a heat-conducting base according to claim 1, wherein each penetrating hole is a through hole or blind hole.

4. The method for combining axially heated heat pipes and a heat-conducting base according to claim 1, wherein each penetrating hole is distributed on the heat-conducting base to be heated in a concentric manner.

5. The method for combining axially heated heat pipes and a heat-conducting base according to claim 1, wherein a heat-conducting paste is applied between the end to be heated of each heat pipe and the penetrating hole so as to fill a gap therebetween.

6. The method for combining axially heated heat pipes and a heat-conducting base according to claim 1, wherein a soldering material is heated to be molten and thus filled into a gap between the end to be heated and the penetrating hole.

7. The method for combining axially heated heat pipes and a heat-conducting base according to claim 6, wherein the soldering material is a soldering paste.
