Abstract

A heat pipe mounting method and a heat pipe assembly thereof are disclosed. The method includes the step of providing a heat-transfer block and a plurality of heat pipes. A plurality of heat pipe grooves is formed on the heat-transfer block. The heat pipes are then press-fitted to respective heat pipe grooves. During the press-fitting step, the heat pipes are flattened to force the flattened part of one heat pipe into abutment against the flattened part of another heat pipe in a flushed manner. Thereby, the heat pipes are abutted to each other with no separation therebetween. Hence, the heat transfer performance is increased.

Claims

1. A heat pipe mounting method, comprising the steps of:

a) providing a heat-transfer block and a plurality of heat pipes, a plurality of heat pipe grooves being formed on the heat-transfer block for accommodating respective heat pipes, a supporting rib being formed between each heat pipe groove, a tip portion being formed on the supporting rib;

b) press-fitting the heat pipes into respective heat pipe grooves; and

c) flattening the heat pipes to force the flattened parts of the heat pipes into abutment against one another in a flushed manner when press-fitting the heat pipes into respective heat pipe grooves.

2. The heat pipe mounting method as claimed in claim 1, wherein a protrusion is formed on the supporting rib toward one of the adjacent heat pipe groove in step a).

3. The heat pipe mounting method as claimed in claim 1, wherein a protrusion is formed on the supporting rib toward each adjacent heat pipe groove in step a).

4. The heat pipe mounting method as claimed in claim 1, 2 or 3, wherein at least one fixing rib is protruded on the heat pipe groove in step a).

5. The heat pipe mounting method as claimed in claim 4, wherein the flattened part of the heat pipe extends along and over the tip portion of the supporting rib in step c).

6. The heat pipe mounting method as claimed in claim 1, 2 or 3, wherein the flattened part of the heat pipe extends along and over the tip portion of the supporting rib in step c).

7. The heat pipe mounting method as claimed in claim 1, wherein a flat heat-absorbing surface is formed on the heat pipe by flattening the exposed portion thereof during step c).

8. The heat pipe mounting method as claimed in claim 7, wherein the heat-absorbing surface of each heat pipe is flushed coplanarly.

9. A heat pipe assembly, comprising:

a heat-transfer block having a surface, a plurality of closely arranged heat pipe grooves being formed on the surface, a supporting rib being formed between each heat pipe groove, a tip portion being formed on the supporting rib; and

a plurality of heat pipes press-fitted into respective heat pipe grooves, an abutting portion being formed on the heat pipe along each tip portion of the adjacent supporting rib, the abutting portions between each heat pipe are flushed against one another.

10. The heat pipe assembly as claimed in claim 9, wherein the surface is defined as a bottom surface of the heat-transfer block.

11. The heat pipe assembly as claimed in claim 10, wherein a top surface is formed on the heat-transfer block opposite to the bottom surface, and wherein a plurality of heat-dissipating fins is disposed on the top surface of the heat-transfer block.

12. The heat pipe assembly as claimed in claim 9, wherein the heat pipe grooves of the heat-transfer block are arched slightly larger than semi-circularly shaped.

13. The heat pipe assembly as claimed in claim 9, wherein the tip portion of the supporting rib of the heat-transfer block is short of flushing coplanarly with the bottom surface of the heat-transfer block.

14. The heat pipe assembly claimed in claim 9, wherein a protrusion is formed on the supporting rib toward one of the adjacent heat pipe groove.

15. The heat pipe assembly as claimed in claim 9, wherein a protrusion is formed on the supporting rib toward each adjacent heat pipe groove.

16. The heat pipe assembly as claimed in claim 9, 14 or 15, wherein at least one fixing rib is protruded on the heat pipe groove.

17. The heat pipe assembly as claimed in claim 16, wherein the fixing rib impresses into the corresponding heat pipe and forms an impression thereon.

18. The heat pipe assembly as claimed in claim 9, wherein abutting portions between each heat pipe cover the corresponding tip portion of the supporting rib.

19. The heat pipe assembly as claimed in claim 9, wherein a heat-absorbing surface is formed on the heat pipe exposing from the heat pipe groove.

20. The heat pipe assembly as claimed in claim 19, wherein a protruding block is disposed on the heat-absorbing surface of the heat pipe in parallel.
