Description
TECHNICAL FIELD
[0001] The utility model relates to heat transfer device technical field especially relates to a multi -passage condensation heat dissipation's gravity heat pipe.
BACKGROUND
[0002] The gravity heat pipe is composed of three parts: evaporation section, adiabatic section and condensation section. A closed cavity is formed inside the gravity heat pipe body. When the gravity heat pipe works, the working medium in the heat pipe absorbs heat in the evaporation section of the heat pipe and vaporizes into steam. The steam flows to the condensation section under the action of pressure difference and releases heat above the condensation section to condense into liquid. The liquid flows back to the evaporation section by condensation under the action of gravity, and the cycle is repeated to realize heat transfer.
