SHEET-TYPE HEAT PIPE AND MOBILE TERMINAL USING THE SAME

摘要

Provided is a sheet-type heat pipe that has a sufficient heat transport capability and can be effortlessly installed in a thin chassis. The sheet-type heat pipe is made of a sealed container having a thickness of not larger than 0.5 mm. This container is formed by stacking and diffusion-joining together etched sheet bodies. Particularly, etching is performed on one side surface of each of the sheet bodies such that fine concavities and convexities can be formed on the inner surface of the container and the sheet-type heat pipe with a sufficient heat transport capability can thus be obtained even when the thickness of the container is not larger than 0.5 mm. More particularly, since the thickness of the container is formed to not larger than 0.5 mm, the sheet-type heat pipe can be effortlessly installed in a thin chassis such as that of a mobile terminal.

主权项

1. A sheet-type heat pipe comprising:
at least two etched metal sheets including a first metal sheet and a second metal sheet; and a container that is formed by stacking together said metal sheets and is sealed by joining at least a part of an outer circumferential portion thereof.
