HEAT PIPE

摘要

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.

主权项

1. A sheet-shaped heat pipe comprising:
a container in which a hollow portion is formed; a wick structure that is stored in the container and generates a capillary force; and working fluid that is sealed in the hollow portion formed in the container, wherein the hollow portion formed in the container includes a wick-occupied portion that is occupied by the wick structure, and a space portion that is not occupied by the wick structure, a protruding portion is provided on at least a part of the wick-occupied portion and the space portion, the protruding portion is formed in a shape in which a widthwise cross-section of the protruding portion protrudes in height directions of the wick-occupied portion and the space portion, and the longitudinal direction of the protruding portion extends along the surface of the container, and the protruding portion is provided so that the height of the wick-occupied portion is larger than the height of the space portion.
