Document Type and Number:
WIPO Patent Application WO/2022/185908
Kind Code:
A1
Abstract:
The present invention provides a heat pipe that has excellent circulation properties for a working fluid, that makes it possible to prevent abnormal noise from occurring during circulation of the working fluid, and that demonstrates excellent heat transport properties. This heat pipe is provided with: a container which is a tube and has a sealed end surface at one end and the other end; a wick structure provided to the interior of the container; and a working fluid sealed in the interior of the container. In at least one cross-section of the cross-sections of the direction orthogonal to the longitudinal direction of the container, the wick structure includes: a first wick part having a thickness of 50% or more of the height of an interior space of the container; and a second wick part that is integrated with the first wick part, stretches to an outer direction from the first wick part, and has a thickness of less than 50% of the height of the interior space of the container, the second wick part having a flat section that extends along a direction orthogonal to the height direction of the interior space of the container.
