Heat pipe assembly
View Patent ↗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.
1. A heat pipe assembly comprising;
a heat pipe enclosing space for working fluid, at least a portion of said heat pipe enclosing said space being flattened,
a metallic web wick structure compressed and attached to the internal surface of the heat pipe by a mesh supporting member disposed against the wick structure, said mesh supporting member comprising a nonwoven combination of strips;
said strips comprising a first layer of radially extending discrete strips spaced from each other along the axis of the heat pipe, and a second layer of axially extending strips disposed generally orthogonally to the radially extrending strips;
said nonwoven combination of strips forming mutually communicable working fluid channels in the flattened portion of the heat pipe.
2. The heat pipe assembly as recited in claim 1 , wherein the mesh supporting member comprises a structure having capillary forces.
3. The heat pipe assembly as recited in claim 2 , wherein the structure having capillary forces comprises soldering powders.
4. 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 misaligned.
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 mutually aligned.
6. The heat pipe assembly as recited in claim 1 , wherein the cross section of the radially and axially arranged stripes is rectangular.
7. The heat pipe assembly as recited in claim 1 , wherein the cross section of the radially and axially arranged stripes is circular.
8. The heat pipe assembly as recited in claim 1 , wherein the cross section of the radially and axially arranged stripes is trapezoidal.
9. The heat pipe assembly as recited in claim 1 , wherein the cross section of the radially and axially arranged stripes is triangular.
10. The heat pipe assembly as recited in claim 1 , wherein the radially and axially arranged stripes are equally spaced.
11. The heat pipe assembly as recited in claim 1 , wherein the radially and axially arranged stripes are unequally spaced.
12. The heat pipe assembly as recited in claim 1 , wherein the geometrical dimension of the radially and axially arranged stripes in inhomogeneous.
13. The heat pipe assembly a recited in claim 12 , wherein the cross section area of the radially arranged stripes is large that of the axially arranged stripes.
14. The heat pipe assembly as recited in claim 12 , wherein the radially and axially arranged stripes comprise cross section area of different shapes.
