Abstract

A method for connecting heat pipes and a heat sink comprises the steps of drilling a set of through holes through a heat dissipating base slab, implanting heat pipes through the through holes, integrating the heat-dissipating base slab with the heat pipes by punching using a press machine, and bending and twisting the heat pipes according to a predetermined angle and shape, whereby a set of radiation fins will be connected. The heat radiating device thereby produced is used on electronic elements.

Claims

1. A method for connecting a plurality of heat pipes and a heat sink, comprising the steps of:

(1) drilling a set of through holes through a heat dissipating base slab;

(2) implanting at least one heat pipe through one of said through holes;

(3) press-shaping said heat-dissipating base slab inserted with said heat pipe so that said heat-dissipating base slab and said heat pipe are integrated by mutual deformation;

(4) bending and twisting said heat pipe according to a predetermined angle and shape, whereby a set of radiation fins will be connected.

2. The method for connecting a plurality of heat pipes and a heat sink of claim 1 further including a step of applying a press machine in said step of press-shaping perpendicular to said combination of said heat dissipating base slab and said heat pipes so as to form a local deformed region to assist said integration of said heat dissipating base slab and said heat pipes.

3. The method for connecting a plurality of heat pipes and a heat sink of claim 2 wherein said press machine consists of an upper and lower casting parts each having a side facing the other casting part provided with an impression portion;

said upper and lower casting parts pressing said heat dissipating base slab and said heat pipes to form an integral body.

4. The method for connecting a plurality of heat pipes and a heat sink of claim 1 wherein said step of bending and twisting is an extension of said heat pipes toward one side of said heat dissipating base slab for connecting a plurality of heat radiation fins.

5. The method for connecting a plurality of heat pipes and a heat sink of claim 1 wherein said step of bending and twisting is an extension of said heat pipes by two opposite sides of said heat dissipating base slab for connecting a set of heat radiation fins.

6. A method for connecting a plurality of heat pipes and a heat sink, comprising the steps of:

(1) drilling a set of through holes through a heat dissipating base slab and forming at least a depressed portion on at least one side of said heat dissipating base slab;

(2) implanting at least one heat pipe through one of said through holes;

(3) press-shaping said heat-dissipating base slab inserted with said heat pipe so that said heat-dissipating base slab and said heat pipe are integrated by mutual deformation;

(4) bending and twisting said heat pipe according to a predetermined angle and shape, whereby a set of radiation fins will be connected.

7. The method for connecting a plurality of heat pipes and a heat sink of claim 6 further comprising the step of utilizing a press machine consisting of an upper and lower casting parts each having a side facing the other casting part, said oppositely facing sides each being provided with an impression portion corresponding to said depressed portions;

(4) bending and twisting said heat pipe according to a predetermined angle and shape, whereby a set of radiation fins will be connected.

10. The method for connecting a plurality of heat pipes and a heat sink of claim 9 wherein said upper and said lower rows of through holes are aligned so that each of said through holes of said upper row is located right above one of said through holes of said lower row.

11. The method for connecting a plurality of heat pipes and a heat sink of claim 9 wherein said upper and said lower rows of through holes are aligned so that each of said through holes of said upper row is located above the mid point between two adjacent through holes of said lower row.

12. The method for connecting a plurality of heat pipes and a heat sink of claim 9 wherein said heat dissipating base slab further has at least one surface provided with at least a surface portion selected from a depressed portion, a bulged portion and a mixture of a bulged portion and an internal passage.
