Abstract

In a method for juxtaposing and combining a plurality of heat pipes with a fixing base, first, a fixing base having an accommodating trough is provided. The accommodating trough is provided therein with at least one recess. Further, a plurality of heat pipes is provided. Adhesive medium is coated on the contacting surface between the heat pipe and the accommodating trough. The plurality of heat pipes is pressed into the accommodating trough. Finally, the heat pipes juxtaposed in the accommodating trough are pressed coplanarly the surface of the fixing base while a portion of the adhesive medium is received in the recess.

Claims

1. A method for combining heat pipes (20) with a fixing base (10), comprising the steps of:

a) providing a fixing base (10) having an accommodating trough (12) on a bottom surface (11) thereof, the accommodating trough (12) being provided therein with at least one recess (13);

b) providing at least two heat pipes (20);

c) coating adhesive medium (30) on a contacting surface between the heat pipes (20) and the accommodating trough (12);

d) pressing the heat pipes (20) in the accommodating trough (12) with a portion of adhesive medium (30) being received in the recess (13); and

e) pressing the heat pipes (20) juxtaposed in the accommodating trough (12), thereby making the heat pipes (20) coplanarly the surface of the fixing base (10).

2. The method according to claim 1, wherein the step c) is to coat the adhesive medium (30) on the surface of the heat pipes (20).

3. The method according to claim 1, wherein the step c) is to coat the adhesive medium (30) on the surface of the accommodating trough (12).

4. The method according to claim 1, wherein in the step d), one of the heat pipes (20) is disposed first in the accommodating trough (12), and then at least one heat pipe (20) is pressed into the accommodating trough (12).

5. The method according to claim 1, wherein in the step d), the heat pipes (20) are juxtaposed in an opening of the accommodating trough (12), and the juxtaposed heat pipes (20) are pressed into the accommodating trough (12) simultaneously.

6. The method according to claim 1, wherein the recess (13) is a hole.

7. The method according to claim 1, wherein the recess (13) is an elongate slot.

8. The method according to claim 1, wherein the adhesive medium (30) is epoxy resin.

9. The method according to claim 1, wherein the adhesive medium (30) is heat-conducting glue.

10. The method according to claim 1, wherein the adhesive medium (30) is thermosetting adhesive medium.

11. The method according to claim 10, further comprising a step f) of heating the adhesive medium (30) to melt.

12. A structure of combining heat pipes (20) with a fixing base (10), comprising:

a fixing base (10) having an accommodating trough (12) on a bottom surface (11) thereof, the accommodating trough (12) being provided with at least one recess (13);

at least two heat pipes (20) juxtaposed in the accommodating trough (12), the surfaces of the juxtaposed heat pipes (20) being pressed coplanarly the surface of the fixing base (10); and

adhesive medium (30) coated between the heat pipes (20) and the accommodating trough (12), a portion of the adhesive medium (30) being received in the recess (13).

13. The structure of combining heat pipes with a fixing base according to claim 12, wherein the recess (13) is a hole.

14. The structure of combining heat pipes with a fixing base according to claim 12, wherein the recess (13) is an elongate slot.

15. The structure of combining heat pipes with a fixing base according to claim 12, wherein the adhesive medium (30) is epoxy resin.

16. The structure of combining heat pipes with a fixing base according to claim 12, wherein the adhesive medium (30) is heat-conducting glue.

17. The structure of combining heat pipes with a fixing base according to claim 12, wherein the adhesive medium (30) is thermosetting adhesive medium.
