Heat pipe, manufacturing method of heat pipe and equipment comprising heat pipe

Abstract

The invention discloses a heat pipe, a manufacturing method of the heat pipe and equipment comprising the heat pipe, mainly relates to a capillary core of the heat pipe and a manufacturing method of the capillary core, and belongs to the technical field of heat conduction. According to the manufacturing method, a positioning tool and a metal net are mainly used, metal powder is arranged and limited in a specific space position in a pipe shell, and the technical problems that in the sintering process in which a traditional method is adopted, the metal powder is bonded with a core rod, when thecore rod is pulled out after sintering, the capillary core is prone to damage, and even a waste product occurs, and the technical problems that core rod is used for separating the reducing atmospherefrom the metal powder, so that the reducing effect is poor, secondary sintering is generally needed, and the energy consumption and the thermal pollution are large can be comprehensively or correspondingly solved; and the technical situations that the capillary core of the sintered layer is damaged due to the deformation processes of bending, flattening and the like can be relieved or avoided, andthe process route in which bending is carried out first, and then sintering is carried out can be realized. The method is applied to manufacturing of the heat pipes (including hot columns and ultra-thin heat pipes). The heat pipe is applied to equipment or a device requiring heat transfer or heat dissipation through the heat pipe.
