Abstract
A support structure of a heat-pipe multi-layer wick structure, having a hollow heat-pipe tube and multiple separate layers of weaving mesh wick structure overlaying on an interior surface of the heat-pipe tube. The wick structure has a curly circular shape. The outermost layer of the wick structure has finer mesh compared to the inner layers of thereof. Thereby, the capillary force of the heat pipe is enhanced, while the coarse mesh at the inner layers provide better support to the outer layers of the wick structure.

A heat pipe, comprising:
- a tubular member;
- a wick structure, comprising multiple layers of weaving meshes, wherein an outermost weaving mesh of the wick structure is directly attached to an interior surface of the tubular member, and the outermost weaving mesh is finer than the other weaving mesh here the outmost weaving mesh and the other weaving meshes each has a plurality of longitudinal extending along an axis of the tubular member and a plurality of transverse we extending about the axis and the longitudinal wires and the transverse wires are fabricated from materials having different melting points;
- and
- wherein before an external force is applied, the inserted first weaving mesh and the second weaving mesh would form two open circles and after the external force is applied, the diameter of the tubular member will be reduced to a predetermined size where both open-circles become enclosed.

A support structure of a multi-layer wick structure attached to a tubular member fabricated by the steps of:
- overlying a first weaving mesh and a second weaving mesh, wherein the first weaving mesh is finer than the second weaving mesh;
- winding the first and the second weaving meshes into an open circular wick structure with the first weaving mesh encircling the second weaving mesh;
- inserting the open circular wick structure into the tubular member;
- shrinking the diameter of the tubular member to press the open circular wick structure into a close circular wick structure;
- and
- melting the first weaving mesh to firmly attach on an interior surface of the tubular member by an annealing process.
A support structure of a multi-layer wick structure attached to a tubular member of a heat pipe, comprising:
- a first weaving mesh which is sandwiched between a second weaving mesh and an interior surface of the tubular member, wherein the wires of the first weaving mesh is finer than the wires of the second weaving mesh, and the fist and the second weaving meshes comprise a plurality of longitudinal wires extending along an axis of the tubular member and a plurality of transverse wires extending about the axis and the longitudinal wires and the transverse wires are fabricated from materials having different melting points;
- and
- wherein before an external force is applied, the inserted first weaving mesh and the second weaving mesh would form two open circles and after the external force is applied, the diameter of the tubular member will be reduced to a predetermined size where both open-circles become enclosed.
