Modified type unidirectional gravity force hot pipe

Abstract

The invention discloses an improved unidirectional gravity assisted heat pipe which comprises a sealed chamber (4), and proper quantity of heat pipe working fluid (5) sealed in the sealed chamber (4). The pipe body is divided into a condensation section (1), an evaporation section (3) and an insulation section (2) arranged between the condensation section (1) and the evaporation section (3). The condensation section (1) is arranged on the top of the gravity assisted heat pipe, and the evaporation section (3) is arranged at the bottom of the gravity assisted heat pipe. The enclosers of the condensation section (1) and the evaporation section (3) are made of materials with high coefficient of heat conductivity; the insulation section (2) is made of insulant different from the condensation section (1) and the evaporation section (3). When the temperature of the evaporation section (3) is higher than the temperature of the condensation section (1), heat is transferred to the condensation section (1) of lower temperature under the action of the gravity assisted heat pipe. When the temperature of the evaporation section (3) is lower than the temperature of the condensation section (1), heat can not be transferred to the evaporation section (1) along the shell of the gravity assisted heat pipe, thus preventing heat from being transferred inversely along the shell of the gravity assisted heat pipe and achieving the unidirectional thermal conduction of the gravity assisted heat pipe. The improved unidirectional gravity assisted heat pipe is applicable for unidirectional transfer of heat of gravity assisted heat pipes which are strictly required.

Description

technical field [0001] The invention relates to an improved one-way gravity heat pipe which can overcome the heat transfer of metal pipe shells and has strict one-way thermal conductivity. Background technique [0002] At present, the shells of gravity heat pipes are all made of materials with high thermal conductivity, the evaporation section is located at the bottom, and the condensation section is located at the top. When the temperature of the evaporating section is higher than that of the condensing section, heat is transferred from the evaporating section to the condensing section. When the temperature of the evaporating section is lower than that of the condensing section, the gravity heat pipe cannot transfer heat, so the gravity heat pipe can realize one-way heat transfer. However, the shells of traditional gravity heat pipes are made of materials with high thermal conductivity. When the temperature of the condensing section is higher than that of the evaporating se...

Problems solved by technology

Although the heat transfer capacity of the metal shell is much lower than that of the gravity heat pipe, in some applications that strictly require the one-way heat transfer of the gravity heat pipe, the reverse transfer of heat may bring some adverse effects
