The bendable region occupies a small proportion of the whole machine, and the graphite film in the bendable region mainly plays a role in heat conduction, so that heat exchange on two sides of the bendable region is realized. However, the graphite film is easily wrinkled or even broken after being deformed by multiple times of stretching, so that the heat conduction function of the graphite film is weakened or even completely lost, and further, the heat exchange at two sides of the bendable region is blocked, and the heat can not be smoothly radiated at the same temperature.

Example 1
Referring to fig. 1 to 5, the present embodiment provides a heat dissipation film 100 applied to a foldable display device to make the foldable display device dissipate heat at a uniform temperature. The heat dissipation film 100 includes a heat conduction region 110 and a temperature equalizing region 120, wherein the heat conduction region 110 is located in a bendable region of the foldable display device, and the temperature equalizing region 120 is disposed at two ends of the heat conduction region 110. It is understood that in other embodiments, the number and the positions of the heat conduction area 110 and the temperature equalizing area 120 may be set as required, for example, the heat dissipation film 100 only includes one heat conduction area 110 and one temperature equalizing area 120, and the temperature equalizing area 120 is set at one end of the heat conduction area 110; for another example, the heat dissipation film 100 includes two heat conduction areas 110 and a temperature equalizing area 120, and the heat conduction areas 110 are disposed at two ends of the temperature equalizing area 120.
When the temperature equalizing area 120 is used, the temperature equalizing area is attached to the main board, the battery, the framework, the shell and other structures of the foldable display device, and the heat generated by the main board, the battery and other structures is transferred to the framework, the shell and other structures by utilizing the excellent heat conducting performance of the material, so that the temperature equalizing is realized in the area opposite to the temperature equalizing area 120, and the effective heat dissipation area of the foldable display device is increased. In addition, the heat of the two temperature equalizing regions 120 is transferred through the heat conducting region 110, so that the temperature equalization is achieved in the region opposite to the whole heat dissipation film 100, and the effective heat dissipation area of the foldable display device is further increased.
In particular, the heat conduction area 110 is provided with at least one extension 111. When the foldable display device is bent, the extension 111 on the heat conduction region 110 is unfolded, thereby stretching the heat conduction region 110 to accommodate the length change of the bendable region. When the foldable display device is straightened from the bent state, the extension parts 111 of the heat conduction areas 110 are folded, so that the length of the heat conduction areas 110 is reduced. The above-mentioned "unfolding" and "folding" are to be understood as length changes in at least one direction, such as an increase in length in one direction to "unfolding" and a decrease in length in one direction to "folding".
The length change of the heat conduction area 110 is completed by the expansion and contraction of the extension part 111, rather than by the expansion and contraction of the heat dissipation film 100, so that the heat conduction area 110 does not wrinkle or even break after being folded for many times, and the temperature equalizing areas 120 at the two ends of the heat conduction area 110 can stably conduct heat through the heat conduction area 110, thereby effectively equalizing the temperature and dissipating the heat.
Specifically, the extension 111 is provided as a protrusion. When the heat dissipation film 100 is processed, the original straight heat dissipation film 100 is placed on the jig and is extruded while being heated, so that the local part of the heat dissipation film 100 is slightly shaped to form a bulge.
The protrusion may extend from one side of the heat conduction region 110 to the other side, or may extend from the other side of the heat conduction region 110 to one side. When the number of the protrusions is greater than or equal to two, a part of the protrusions may extend from one side of the heat conductive area 110 to the other side, and another part of the protrusions may extend from the other side of the heat conductive area 110 to one side.
Referring to fig. 3, in an embodiment, the protrusions extending from one side of heat conducting region 110 to the other side and the protrusions extending from the other side of heat conducting region 110 to one side are disposed at intervals one by one to form a wave-like structure. Of course, the present application is not limited to the spacing of the projections extending in different directions.
Wherein, the side of the heat conduction area 110 is parallel to the connection line direction of the two temperature equalizing areas 120. In the present embodiment, the protrusions extend in a direction perpendicular to the side of the heat conduction area 110, and the plurality of protrusions are disposed at intervals in a direction parallel to the side of the heat conduction area 110.
During the unfolding process, the height of the protrusion extending outwards is gradually reduced, and the two sides are far away from each other, i.e. the width is gradually increased, so that the length of the heat conduction area 110 is increased. In the process of folding the protrusion, the height of the protrusion extending outward is gradually increased, and the two side edges are close to each other, i.e. the width is gradually reduced, so that the length of the heat conduction area 110 is reduced.
In the direction parallel to the side of the heat conducting area 110, the widths of the protrusions before and after bending are W1 and W2, respectively, and if the number of the protrusions is n, the expansion and contraction amount of the heat conducting area 110 before and after bending is (W1-W2) × n.
Further, the heat conduction area 110 is likely to rub against other structures of the bendable area during the expansion and contraction process, and in order to avoid damage of the heat conduction area 110 after multiple rubs, the wear-resistant layer 100c is disposed on the heat conduction area 110. The wear resistant layer 100c has good wear resistance and can protect the structure in the heat conducting area 110, which plays a role in heat conduction.
In this embodiment, the heat dissipation film 100 is made of graphite, graphene or carbon composite fiber, and is covered with a protective film, and the wear-resistant layer 100c is made of teflon.
Specifically, the heat conduction area 110 may be divided into four layers, which are a protective layer 100a, a heat conduction layer 100b, a protective layer 100a, and an abrasion resistant layer 100c in this order in the thickness direction. The temperature equalizing zone 120 is divided into three layers, which are a protective layer 100a, a heat conductive layer 100b, and a protective layer 100a in this order along the thickness direction.
The protective layer 100a may be a PI (Polyimide) film or a CPI (Colorless transparent Polyimide) film, and the heat conductive layer 100b may be a graphite layer, a graphene layer, a composite carbon fiber layer, or a graphite layer coated with graphene. It is understood that in other embodiments, the heat dissipation film 100 may be a polymeric material that is a blend of materials.
Further, since the foldable display device occupies a smaller proportion of the bendable region, the line width of the bendable region is limited, and the area of the heat conducting region 110 is set to be smaller than that of the uniform temperature region 120 for the purpose of reducing stress at the time of bending.
In the present embodiment, the heat dissipation film 100 is composed of a heat conduction area 110 and two temperature equalization areas 120, and is suitable for a foldable display device that is folded in two sections. In another embodiment of the present application, the heat dissipation film 100 may also be composed of two heat conduction areas 110 and three temperature equalization areas 120, and is suitable for a foldable display device folded in three sections.

Specifically, two middle frames 300 are provided, and the two middle frames 300 are rigid structures and serve as mounting bases for other elements.

In addition, the two middle frames 300 are respectively provided with a rear cover 310 for enclosing the first electrical component 500 and the second electrical component 600 therein.

In addition, a wire passing groove is formed in the middle of the hinge 200 for the flexible circuit board 700 to pass through. The hinge covering piece 210 is installed at the notch of the wire passing groove to encapsulate the flexible circuit board 700 in the wire passing groove.
Specifically, the flexible screen 400 covers the middle frame 300 and the hinge 200, and is fixedly connected to a side of the middle frame 300 opposite to the rear cover 310. The flexible screen 400 is supported by the hinge 200 at the middle portion thereof and is bent along with the hinge 200.
Specifically, the temperature equalizing region 120 of the heat dissipating film 100 is opposite to the middle frame 300, so that the heat within the middle frame 300 is distributed as uniformly as possible. The heat conduction area 110 is connected with the hinge 200, the heat exchange between the two temperature equalizing areas 120 is realized while the heat conduction area is bent along with the hinge 200, and the wear-resistant layer 100c is positioned on one side of the heat conduction area 110, which faces the hinge 200. Since the hinge 200 is typically made of metal or alloy material, the connection of the heat conducting area 110 to the hinge 200 also facilitates the heat conducting area 110 to conduct heat to the hinge 200 for heat dissipation.
In this embodiment, the heat dissipation film 100 is disposed on a side of the hinge 200 facing the flexible panel 400, and the temperature equalizing regions 120 are respectively attached and fixed to a side of the middle frame 300 facing the flexible panel 400.

Further, the heat conduction area 110 is provided with a plurality of first connecting portions 112. The first connecting portion 112 is fixed on the hinge 200 by dispensing or double-sided adhesive tape, so that the heat conducting area 110 is not prone to deviation in the bending process, and the extending portions 111 are uniformly distributed in the bendable area, thereby facilitating stable extension and retraction of the heat conducting area 110.
In the present embodiment, the first connection portions 112 and the extension portions 111 are alternately arranged in a direction parallel to the side edges of the heat conduction area 110.
In another embodiment, the first connection portion 112 is located on the extension portion 111. More specifically, the first connection portion 112 is located at a convex top end of the extension portion 111 to facilitate connection with the hinge 200.
