Abstract

The invention relates to a device for filling a dual process interface heat pipe with solid working mediums. The device comprises a glovebox, a working medium tank, an upper cover, an inert gas source, a vacuum molecular pump set, a heater and a cooler and the like. First dual process interface design is adopted, a main process interface is a vacuumizing interface and inert gas access interface and is also a working medium filling interface, an auxiliary process interface is a vacuumizing interface and is also an inert gas access interface, an exhaust passage of the heat pipe and a process tank is increased by one time, exhaust vacuumizing is smoother, the filling range can be expanded as required; an air pillow and a screen drum are added; novel design is performed on the cooler and the heater; the filling process is optimized, and the goals of heat pipe charging range expansion according to the requirements, no working medium residue on a pipeline during the filling, a more stable process, higher working medium purity, more convenient aftertreatment, more excellent heat pipe performance and longer service life are achieved.

Description

technical field [0001] The invention relates to a solid working medium filling device and a filling method for a dual-process interface heat pipe, and belongs to the technical field of heat pipe key process processes in the subject of engineering thermophysics. Background technique [0002] The concept of heat pipes has been extended to heat pipe plates (two-dimensional) and even heat pipe steam chambers (three-dimensional). At present, to meet the needs of special thermal control occasions, it is required to design the shape and internal space of the heat pipe to increase continuously. The demand for large-capacity heat pipe plates and heat pipes in steam chambers continues to increase. [0003] High-temperature heat pipes (when the working temperature reaches or exceeds 500°C) and ultra-high-temperature heat pipes (when the working temperature reaches or exceeds 1200°C) generally use alkali metals, lead, silver, etc. as working fluids, and these working fluids are mostly ...
