Abstract

The invention discloses a high-temperature sodium heat pipe filling device and method. The device comprises a transparent sealing box, a sodium storage tank, a filtering tank, a known volume tank, a vacuum pump, a heat pipe shell, a vacuum gauge, a humidity controller and the like. The transparent sealing box provides a closed space for the device; the sodium storage tank is used for storing and heating metal sodium; the filtering tank is used for removing impurities in the liquid metal sodium; the heat pipe shell is used for storing high-purity liquid metal sodium; the vacuum gauge and the vacuum pump are used for providing and monitoring a certain vacuum degree; and the humidity controller is used for controlling the humidity in the transparent sealing box. According to the invention, the specification of the high-temperature sodium heat pipe during processing and manufacturing can be ensured, so that the standardized production of the high-temperature sodium heat pipe becomes possible.

Description

technical field [0001] The invention relates to the technical field of phase change heat equipment, in particular to a high temperature sodium heat pipe filling device and method. Background technique [0002] The heat pipe is one of the heat transfer elements with the highest heat transfer efficiency in the current research. It uses the phase change of the working medium to transfer heat through gravity, centripetal force and capillary force. The sodium heat pipe works stably under high temperature conditions, has high heat transfer efficiency, and has a structural Simple, isothermal, and inherently safe, it has broad application prospects. However, there are still problems such as irregularity and poor cleanliness in the processing and manufacturing of sodium heat pipes at present, especially in the stage of filling working medium, which cannot meet the quantitative and clean requirements, resulting in limited heat transfer performance of sodium heat pipes. Aiming at the ...
