Abstract: A heat pipe suited for thinning, and achieving high heat transport performance is provided. A heat pipe 1 according to the invention includes working liquid, a container 2 into which the working liquid is sealed, and a mesh member 3 disposed in such a position as to come into contact with at least two inner surfaces of the container, the two surfaces facing to each other. The mesh member 3 is formed by a plurality of meshes 31 and 32 laminated on each other. The porosity in the portion where the respective meshes 31 and 32 contact each other is lower than the porosity in the portion where the meshes 31 and 32 contact the container 2.

Abstract: The purpose of this invention is to provide a sheet-shaped heat pipe that makes it possible to reduce a pressure loss caused by a vapor flow or a pressure loss caused by a working fluid flow to improve the maximum amount of heat to be transported and reduce thermal resistance by increasing the cross-sectional area of a vapor flow passage or a fluid flow passage, which has been limited by the length of a container in a height direction. A heat pipe (20) is provided with a protruding portion (24) so that the height of the wick-occupied portion (23) serving as the fluid flow passage is larger than the height of the space portion (22) serving as the vapor flow passage.

Abstract: A planar heat pipe includes a container having a hollow portion provided at a central portion thereof with two opposing plate-shaped bodies, and a working fluid enclosed in the hollow portion. The hollow portion is provided with a wick structure. At least one of the plate-shaped bodies is a composite member of two or more types of metal members that are laminated and integrated. A metal member of the composite member forming a layer that contacts the hollow portion has a thermal conductivity of greater than or equal to 200 W/m·K and a metal member of the composite member forming a layer that contacts an exterior has a thermal conductivity of less than or equal to 100 W/m·K, a peripheral portion of the hollow portion being sealed.
