Abstract:
1. A molding method for forming a thin-profile composite capillary structure having a thickness of between 0.2 millimeters and 0.8 millimeters, the molding method comprising: preparing a metal grid outside of a heat pipe; preparing a metal powder suitable for sintering outside of the heat pipe; attaching a liquid medium outside of the heat pipe onto at least one lateral surface of said metal grid by either spraying, brushing or steeping; uniformly attaching said metal powder onto the lateral surface of said metal grid with said liquid medium outside of the heat pipe, said liquid medium selected from the group consisting of water, an adhesive and an organic solvent; supporting the metal grid onto a surface of a fixture; and fixing said metal powder onto the surface of said metal grid outside of the heat pipe by sintering such that a sintered powder layer having a thickness of between 0.1 millimeters and 0.7 millimeters is formed on the lateral surface of said metal grid.
