Abstract
A solid working medium filling device for heat pipe with double process ports includes a working medium tank, an upper cover, an inert gas source and a vacuum molecular pump set. The upper cover is arranged on an upper side of the working medium tank, a process port in the upper cover is in communication with the inert gas source and the vacuum molecular pump set respectively. A heat pipe to be filled includes two process ports, in which a main process port is a vacuumizing port and an inert gas passage port as well as a working medium filling port; and an auxiliary process port is a vacuumizing port as well as a port for inert gas passage. Size of an exhaust passage of the heat pipe and the process tank is doubled, exhausting and vacuumizing are smooth and the filling range can be enlarged as required.
