Title:
HEAT PIPE
Document Type and Number:
WIPO Patent Application WO/2018/097131
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve thermal transport efficiency without increasing the surface area exclusive to a heat pipe. A heat pipe (1) is provided with a container (2) in which a working fluid is sealed, and a wick (3) provided inside the container. The width of the container in a width direction orthogonal to both the vertical direction and a longitudinal direction is greater than the vertical thickness of the container. A width-direction space (S) is provided between the inner surface of the container and the outer surface of the wick. A plurality of recesses (3a1) that are recessed in the width direction are formed, with longitudinal-direction gaps therebetween, in a first end part (31) of the wick in the longitudinal direction, and no recesses are formed in a second end part (32) of the wick in the longitudinal direction. The width-direction width of the wick, excluding the portions where the recesses are formed, is equal across the entire length of the wick in the longitudinal direction.
