FOLDABLE DISPLAY DEVICE AND HEAT DISSIPATION DEVICE THEREOF

WIPO Patent Application WO/2021/249316

A1

The present application provides a heat dissipation device, a foldable display device, and a terminal device. The heat dissipation device is used for a foldable electronic device, and the heat dissipation device comprises a foldable heat conducting portion, which is used for being folded along with the folding of the electronic device and being unfolded along with the unfolding of the electronic device; a first heat conducting portion which extends from a first side of the folding heat conducting portion and is used for dissipating heat for the electronic device; and a first fixing mechanism which is used for fixing the first heat conducting portion to the electronic device in a movable manner; the first heat conducting portion comprises a first moving mechanism which is used in conjunction with the first fixing mechanism to enable the first heat conducting portion to move relative to the first fixing mechanism. By means of the relative movement of the first heat conducting portion relative to the first fixing mechanism, the first heat conducting portion can adapt to changes in the sectional length of the electronic device in the process of folding and unfolding, thereby satisfying repeated folding of electronic devices and improving the heat dissipation capability of the electronic devices.
