Thermosiphon type heat pipe

Abstract

Abstract PURPOSE:To alleviate restriction of dropping of liquid with a blowing gas and improve a limiting characteristic of thermal transportation by a method wherein a thermal transporting passage between an evaporation part and a condensation part is divided into two sections and a metering part having a minimum sectional area is arranged at a lower part of one flow passage. CONSTITUTION:Heat is applied to an evaporater part 3 from an external source to evaporate a working fluid or boil it, the generated gas may blow up both gas passage 11 and liquid passage 10. However, a metering part 12 is arranged at a lower part, a gas flow rate v2 at the upper end is lower than a flow rate v1 at the upper end of the gas passage 11 and even when liquid generated at a condensation part 1 may not be dropped, the liquid can be dropped from the upper end of the liquid passage 10. When liquid is held at the liquid passage 10, the gas flow rate blowing up within the liquid passage 10 is decreased, and the liquid can drop from the upper end of the liquid passage 10. With such a mechanism as above, finally only the gas is blown up in the gas passage 11 and only the liquid drops at the liquid passage 10 to make a stable condition.
