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 lower melting point compared to the inner layers of thereof. Thereby, the capillary force of the heat pipe is enhanced, while the mesh at the inner layers with higher melting point provides better support to the outer layers of the wick structure.
Claims7
A support structure of a multi-layer wick structure attached to a tubular member of a heat pipe, comprising:
- a first weaving mesh attached to an interior surface of the tubular member;
- and
- a second weaving mesh encircled by the first weaving mesh, wherein the first weaving mesh has a melting point lower than that of the second weaving mesh.
A heat pipe, comprising:
- a tubular member;
- and
- 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 has a melting point lower than the other weaving meshes.
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 has a melting point lower 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 a tubular member;
- shrinking 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.
