Abstract: Disclosed are a device and a method for pressure-molding an anti-overheating CSP fluorescent membrane. The device comprises a frame, a mould pressing device, a force measuring device, a control device and a feeding device; and the mould pressing device comprises an upper pressing mould, an upper clamp, a lower pressing mould, a guide post, an elastic supporting structure, and a lower clamp. As the stage of pressing the elastic supporting structure is added to the course of pressure molding, a mould clamping force of the pressure molding increases in a relatively steady way, and a force impact of a mould clamping device is reduced, thereby easily determining an initial point for maintain temperature of the pressure molding. The present invention effectively prevents overheating caused by long-term and large-area contact between the lower clamp and the heating lower pressing mould, and avoids the process defect of premature melting of the fluorescent membrane due to overheating, thereby greatly improving the product consistency and yield rate of the CSP-package fluorescent membrane in the pressure molding process.

Abstract: A device for forming inside three-dimensional finned tube by multi-edge ploughing and extruding, comprises a machine frame, a machine head, a supporting mechanism, an axial feeding mechanism and a cutter assembly for forming inside fins. The machine head, the supporting mechanism and the axial feeding mechanism are axially mounted on the machine frame in sequence. The cutter assembly for forming inside fins is mounted on the feeding mechanism. One end of a metal tube to be machined for forming inside three-dimensional fins is clamped on a chunk of a rotary main shaft of the machine head, and the other end thereof is placed on the supporting mechanism. The rotary main shaft of the machine head provides the rotation power for the metal tube, and the axial feeding mechanism drives the cutter assembly to move linearly along a coaxial line of the metal tube and the cutter assembly.

Abstract: A method for sealing a high-temperature heat pipe includes: (1) necking and reducing two ends of the heat pipe separately, so as to obtain a necked end and a reduced end; (2) sealing the necked end by laser welding or electron beam welding; (3) placing the heat pipe in an inert gas glove box, and pouring a working medium without impurities into the heat pipe; (4) heating the heat pipe, connecting the reduced end to a vacuum pump, pumping gas inside the heat pipe by the vacuum pump to vacuumize the heat pipe, such that pressure in an inner cavity of the heat pipe reaches a target pressure, and flattening the reduced end; and (5) sealing an opening of the flattened reduced end by electron beam welding or laser welding, so as to obtain the high-temperature heat pipe.
