A flexible display device is provided. The flexible display device includes a display module, a heat plate, a heat collecting component, and a heat conducting tube connecting the heat plate to the heat collecting component. The heat plate transmits heat to a bending portion of the display module when the display module is in an expanded state. By collecting the heat during the operation, the collected heat is applied to the warped bending portion when the flexible display device is flattened, so that the warped bending portion is restored to be flat, thereby improving the product appearance and product stability.

A heat dissipating structure of a foldable electronic device is provided. The electronic device includes a first housing including a first component, a second housing including a second component, a hinge assembly rotatably coupling the first and second housings, a hinge housing accommodating the hinge assembly and disposed between the first and second housings, a flexible display disposed from one region of the first housing to a region of the second housing across the hinge assembly, and foldable depending on a rotation of the hinge assembly, a first plate disposed between the flexible display and the first housing, a second plate disposed between the flexible display and the second housing, and a first heat dissipating structure disposed between the first component and thermally coupled to one end of the hinge housing, and providing a first heat transfer path for transferring heat generated from the first component to the hinge housing.

A device assembly as disclosed herein includes a heat pipe coupled to a heat transfer device, and a thermal interface. The assembly further includes a cold plate rotatably coupled with the heat pipe through a hinge. The thermal interface is coupled with the cold plate through a plane to rotate about the heat pipe together with the cold plate, and the thermal interface includes a material having a thickness and a resiliency configured to make thermal contact with a circuit in a circuit card when the cold plate is rotated over the circuit card. A chassis and a method to build the chassis including the above assembly are also disclosed.

A heat pipe, a heat pipe assembly and a method for assembling the heat pipe assembly. The heat pipe includes a main body part and an insertion part. The insertion part is connected to the main body part. The main body part and the insertion part together form a single hollow pipe. The insertion part has an outer surface and at least one recessed part formed on the outer surface.

A flexible display device is provided, which includes a first housing, a second housing, a hinge structure that connects the first housing and the second housing and supports a hinge motion of the first housing or the second housing, a heat source disposed in the first housing, a heat sink disposed in the second housing, and a heat-dissipation path structure disposed across the first housing, the hinge structure, and the second housing. The heat-dissipation path structure transfers heat generated by the heat source to the heat sink.

A portable information handling system transfers thermal energy associated with operation of processing components in a first housing portion to a thermal exchanger in a second housing portion through a hinge that rotationally couples the first and second housing portions. The hinge has first and second axles that each define a channel. Fluid heated at the first housing portion passes through the channel to the thermal exchanger where thermal energy is rejected from the system. In one embodiment, a second hinge having first and second axles that each define a channel provides a return path for the fluid from the second housing portion to the first housing portion.

A portable information handling system transfers thermal energy associated with operation of a CPU from a main housing portion to a lid housing portion with thermal conduction through a hinge assembly that rotationally couples the main and lid housing portions to each other. For example, thermal conduits insert into a hinge body and transfer thermal energy across the hinge body through a thermally conductive interface, such as the hinge body itself, thermal grease disposed in the hinge body, a liquid that fills a cavity of the hinge body shared by the thermal conduits, and a vapor chamber integrated in the hinge body.

This application provides a heat dissipation apparatus which includes an accommodating part and a heat dissipator assembly. The accommodating part includes an accommodating cavity for accommodating a heating component. The heating component is plugged into the accommodating cavity along a first direction. The heat dissipator assembly includes a heat dissipator, a support, a sliding component, and a linkage part. The support is fixed to the accommodating part. The heat dissipator is connected to the support by using the sliding component. The accommodating part includes a first side surface and a second side surface that are opposite to each other, and the heat dissipator is located on the first side surface. The sliding component includes an oblique slot and a sliding block. The oblique slot gradually approaches the second side surface of the accommodating part along the first direction.

The present embodiment proposes a supportive composite plate, a fabrication method of the supportive composite plate, and a display module. The supportive composite plate applied to a foldable display panel. The supportive composite plate includes a rigid supportive layer and a heat-dissipation layer. The rigid supportive layer includes a first planar portion, a second planar portion, and a bending portion arranged between the first planar portion and the second planar portion. The heat-dissipation layer, embedded in the rigid supportive layer, comprises a first heat-dissipation portion corresponding to the first planar portion, a second heat-dissipation portion corresponding to the second planar portion, and a bridge portion corresponding to the bending portion. The first heat-dissipation portion is connected to the second heat-dissipation portion via the bridge portion.
