Abstract

The invention discloses a hot metal high-temperature heat pipe. The hot metal high-temperature heat pipe comprises a liquid filling pipe, a top end cover, a heat pipe shell, a bottom end cover, a gap,a condensation section liquid absorbing core, a heat insulation section liquid absorbing core, an evaporation section liquid absorbing core, a steam cavity, a liquid absorbing core plug and a gas storage bag. The closed liquid filling pipe, the top end cover, the heat pipe shell and the bottom end cover jointly form a closed space of the heat pipe. The liquid filling pipe is connected with a hotmetal filling loop through a connecting element, and filling of a working medium is achieved. The backflow resistance of the liquid working medium can be reduced through the gap. The evaporation section liquid absorbing core, the heat insulation section liquid absorbing core and the condensation section liquid absorbing core jointly provide power for backflow of the liquid working medium. The wavestructure of the heat insulation section liquid absorbing core can reduce liquid drop entrainment, and the condensation section liquid absorbing core adopts a fin structure to accelerate steam condensation. The liquid absorbing core plug can store the working medium and adjust the mass of the working medium participating in circulation. The gas storage bag can limit non-condensable gas, and the influence of the non-condensable gas on heat transfer is reduced.

Description

technical field [0001] The invention relates to the technical field of phase-change heat equipment, in particular to a liquid metal high-temperature heat pipe. Background technique [0002] The heat pipe is an efficient passive heat transfer device, which has the advantages of high heat transfer efficiency, excellent isothermal performance, simple processing and manufacturing, simple physical structure, and convenient installation and maintenance. A typical heat pipe structure mainly includes a shell, a wick and a working fluid. Heat pipes are usually artificially divided into three parts: the evaporating section, the adiabatic section, and the condensing section. The evaporating section absorbs heat from the heat source, and the working fluid absorbs heat and evaporates; the steam condenses in the condensing section, and the released heat passes through the tube wall of the condensing section to reach the heat sink; the adiabatic section connects the evaporating section an...
