Abstract

A heat pipe assembly includes at least a flattened portion formed on the heat pipe. The internal surface of the heat pipe includes a wick structure attached thereon, and a mesh supporting member disposed therein. The wick structure is compressed on the internal surface of the heat pipe by using the mesh supporting member. The mesh supporting member includes a plurality of radially and axially arranged stripes. The radially and axially arranged stripes are orthogonally stacked, thereby forming mutually communicable working fluid channels in the flattened portion of the heat pipe.

Claims

1. A heat pipe assembly, comprising:

at least a flattened portion formed on the heat pipe;

a metallic web wick structure is compressed and attached to the internal surface of the heat pipe by a mesh supporting member disposed on the wick structure therein; and

the mesh supporting member further comprising alternative layers of radially arranged strips and axially arranged stripes being orthogonally stacked, thereby forming mutually communicable working fluid channels in the flattened portion of the heat pipe.

3. The heat pipe assembly as recited in claim 1, wherein the mesh supporting member comprises a structure having capillary forces.

4. The heat pipe assembly as recited in claim 3, wherein the structure having capillary forces comprises soldering powders.

5. The heat pipe assembly as recited in claim 1, wherein the axially arranged stripes of the mesh supporting member at the upper and lower portion of the flattened portion are usually misaligned.

6. The heat pipe assembly as recited in claim 1, wherein the axially arranged stripes of the mesh supporting member at the upper and lower portion of the flattened portion are mutually aligned.

7. The heat pipe assembly as recited in claim 1, wherein the cross section of the radially and axially arranged stripes is rectangular.

8. The heat pipe assembly as recited in claim 1, wherein the cross section of the radially and axially arranged stripes is circular.

9. The heat pipe assembly as recited in claim 1, wherein the cross section of the radially and axially arranged stripes is trapezoidal.

10. The heat pipe assembly as recited in claim 1, wherein the cross section of the radially and axially arranged stripes is triangular.

11. The heat pipe assembly as recited in claim 1, wherein the radially and axially arranged stripes are equally spaced.

12. The heat pipe assembly as in claim 1, wherein the radially and axially arranged stripes are equally spaced.

13. The heat pipe assembly as recited in claim 1, wherein the geometrical dimension of the radially arranged stripes is inhomogeneous.

14. The heat pipe assembly as recited in claim 1, wherein the cross section area of the radially arranged stripes is larger that of the axially arranged stripes.

15. The heat pipe assembly as recited in claim 13, wherein the radially and axially arranged stripes comprise cross section area of different shapes.
