Description

Technical Field

[0001] The present invention relates to the technical field of temperature averaging plates, and more specifically to an integrally formed flexible temperature averaging plate. Background Art

[0002] Most existing foldable products, such as mobile phones, tablets, or ultra-thin laptops, use back panels for heat dissipation. However, with the launch of flexible screen electronic products, the demand for heat dissipation of electronic products has further increased. The heat spreader of such products requires special molding and is produced using non-conventional methods. However, other manufacturers currently use an organic metal process, which cannot be folded along with the folding screen, resulting in a significant reduction in the heat dissipation area, making it difficult to further improve the heat dissipation effect. After the heat dissipation area is reduced, it is even difficult to maintain the original heat dissipation effect. Summary of the invention

[0007] The coverage area of ​​the upper flexible raw material and the bottom composite raw material metal mesh layer can cover the inner wall of each back panel of the folding product.

[0008] The flexible keel assembly comprises an upper keel flexible bracket, a lower keel flexible bracket, and a keel elastic composite structure, wherein the keel elastic composite structure is located between the upper keel bracket and the lower keel bracket.

[0009] The keel elastic composite structure is a wavy strip.

[0010] The thermal block is located where the processor is installed.

[0011] The two sides of the flexible keel assembly are respectively connected to the upper flexible raw material and the bottom composite raw material metal mesh layer.

[0012] The capillary absorbent core is in the shape of an elongated strip, and the end thereof extends to the edge of the bottom composite raw material metal mesh layer, and the capillary absorbent core is closely attached to the bottom composite raw material metal mesh layer.

[0013] The capillary wick is a copper powder sintering structure, a copper wire weaving structure or a composite copper foam structure.

[0014] The upper flexible raw material is a polyester composite material, which is the material for the foldable display screen.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0022] An integrally formed flexible temperature equalizing plate comprises an upper flexible raw material 1 and a bottom composite raw material metal mesh layer 2, a plurality of flexible keel assemblies 3 are arranged between the upper flexible raw material and the bottom composite raw material metal mesh layer; a heat conductive fixing block 4 is also provided, a composite raw material metal mesh block 5 is fixed to the bottom of the fixing block, both ends of the composite raw material metal mesh block 5 are connected to a capillary wick 6, and the interior is hollow and connected, and the capillary wick 6 is closely attached to the bottom composite raw material metal mesh layer 2.

[0023] Furthermore, the upper flexible raw material layer and the bottom composite raw material metal mesh layer are sealed around each other, and the interior is vacuum.

[0024] Furthermore, the coverage area of ​​the upper flexible raw material and the bottom composite raw material metal mesh layer can cover the back panel of the folding product, for example, the inside of the back panels of the three parts of the tri-fold screen will be covered.

[0025] Furthermore, the flexible keel assembly 3 includes an upper keel flexible bracket 31, a lower keel flexible bracket 32, and a keel elastic composite structure 33, wherein the keel elastic composite structure is disposed between the upper keel bracket and the lower keel bracket. The keel elastic composite structure can be partially connected to the upper keel bracket and the lower keel bracket by welding or bonding.

[0026] Further, such as Figure 4 As shown, the keel elastic composite structure 33 is a wavy strip.

[0027] Furthermore, the heat-conducting fixing block 4 is located at the installation position of the processor 8 .

[0028] Furthermore, two sides of the flexible keel assembly are respectively welded or bonded to the upper flexible raw material layer and the bottom composite raw material metal mesh layer.

[0029] Furthermore, the capillary wick 6 is in the shape of an elongated strip, with the end thereof extending to the edge of the bottom composite raw material metal mesh layer, and the capillary wick is closely attached to the bottom composite raw material metal mesh layer. Embodiment 2

[0030] The heat-conducting fixed block quickly transfers heat to the vacuum capillary flexible cavity, i.e. the capillary wick, through the capillary conductor, so that the maximum area of ​​the cavity is evenly heated to each effective space, and then the heat is transferred to the appearance surface for heat dissipation through the surface of the special composite raw material.

[0031] The entire flexible heat spreader VC cavity needs to be evacuated. The flexible keel assembly can ensure that it can be bent at any angle (laptop or mobile phone, 2-fold, 3-fold, multi-fold), the internal cavity does not collapse, and there is no clogging problem. The capillary wick absorbs the coolant, but it is preheated to become steam. If the bending causes the space to be compressed or blocked, the performance will be partially ineffective, so the flexible keel assembly is a very important design. Embodiment 3

[0032] The upper surface of the heat-conducting fixing block 5 contacts the processor 8 and absorbs the heat of the processor, and conducts it to the composite raw material metal mesh 5, which conducts the heat to the capillary wick 6. The capillary wick 6 disperses the heat to the bottom composite raw material metal mesh layer 2, and the bottom composite raw material metal mesh layer 2 dissipates the heat. Thus, the heat dissipation of the processor can be achieved. Figure 1 The number 7 is the main board. Embodiment 4

[0033] The foldable products to which the present invention can be applied can be mobile phones, laptop computers, servers, wearable products, etc., and can be 20% or 30% folded, etc.

[0034] The shape and size of the flexible keel assembly can be optimized to adjust different shape structures, such as wave shape and rotation shape. No matter how it is optimized and adjusted, its function remains unchanged.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
