Description

Technical Field

[0001] The utility model relates to the technical field of temperature equalizing plates, and more specifically to an integrally formed flexible temperature equalizing plate for folding products. Background Art

[0002] Existing foldable products, such as mobile phones, tablets, and ultra-thin laptops, mostly utilize backplanes for heat dissipation. However, with the arrival of flexible screen electronics, the demand for heat dissipation has further increased. The heat spreaders for these products require specialized molding and unconventional production methods. However, other manufacturers currently use an organic metal process, which cannot fold with the foldable screen. This significantly reduces the heat dissipation area, making it difficult to further improve heat dissipation efficiency. Even with this reduced heat dissipation area, it's difficult to maintain the original heat dissipation efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides an integrally formed flexible temperature equalizing plate for folding products.

[0004] The technical solution of this utility model is as follows:

[0005] An integrally formed flexible temperature equalizing plate for folding products comprises an upper layer of flexible raw material and a bottom layer of composite raw material metal mesh, with a plurality of flexible keel assemblies arranged between the upper layer of flexible raw material and the bottom layer of composite raw material metal mesh; a heat conducting fixing block is also provided, a composite raw material metal mesh block is fixed to the bottom of the heat conducting fixing block, both ends of the composite raw material metal mesh block are connected to a capillary wick, and the capillary wick is in close contact with the bottom layer of composite raw material metal mesh.

[0006] The composite raw material metal mesh block and the capillary liquid absorption core are both hollow inside and communicated with each other.

[0007] 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.

[0008] 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.

[0009] 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.

[0010] The keel elastic composite structure is a wavy strip.

[0011] The thermal block is located where the processor is installed.

[0012] 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.

[0013] The capillary wick is in the shape of an elongated strip, with an end portion 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.

[0014] The capillary wick is a copper powder sintered structure, a copper wire braided structure, or a composite copper foam structure.

[0015] The upper flexible raw material is a polyester composite material, which is the material for foldable display screens.

[0016] The bottom composite raw material metal mesh layer is made of copper mesh.

[0017] Technical effects and advantages of this utility model:

[0018] 1. This structure is formed using a new solution and can be folded 180-360 degrees at will. It is flexible VC and the raw materials used are in line with the environmental protection demands actively promoted by various countries and are low-carbon and environmentally friendly.

[0019] 2. It has mass production capability, simple and easy-to-understand structure, high yield rate, and is suitable for large-scale mass production operations.

[0020] 3. Due to the high yield rate and the absence of additional testing methods or equipment and subsequent processing, the overall cost of the product is reduced, making it competitive in the market.

[0021] 4. Setting up multiple flexible keel assemblies can ensure that it can be bent at any angle (laptop or mobile phone, 2-fold, 3-fold, multiple folds), and the internal cavity will not collapse after folding; it can also compress and deform the capillary wick without clogging problems, thereby preventing local failure of the capillary wick.

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a 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 making creative efforts are within the scope of protection of the present invention. Example 1

[0028] A one-piece flexible temperature equalizing plate for folding products, comprising an upper flexible raw material 1 and a bottom composite raw material metal mesh layer 2, with multiple flexible keel assemblies 3 arranged between the upper flexible raw material and the bottom composite raw material metal mesh layer; a heat-conducting fixing block 4 is also provided, with a composite raw material metal mesh block 5 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 in close contact with the bottom composite raw material metal mesh layer 2.

[0029] Furthermore, the upper layer of flexible raw material and the bottom layer of composite raw material metal mesh are sealed around each other, and the interior is vacuum.

[0030] 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 a folding product, for example, the interior of the three back panels of a tri-fold screen.

[0031] 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. The keel elastic composite structure is disposed between the upper and lower keel brackets. The keel elastic composite structure can be partially connected to the upper and lower keel brackets by welding or bonding.

[0032] Further, such as Figure 4 As shown, the keel elastic composite structure 33 is a wavy strip.

[0033] Furthermore, the heat-conducting fixing block 4 is located at the installation position of the processor 8 .

[0034] 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.

[0035] Furthermore, the capillary wick 6 is in the shape of an elongated strip, with the end portion 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. Example 2

[0036] 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.

[0037] The entire flexible vapor chamber (VC) cavity requires a vacuum. The flexible keel assembly ensures that it can be bent at any angle (like a laptop or phone, folded in two, three, or multiple times) without collapsing or clogging. Capillary wicking absorbs the coolant, but it preheats and turns it into vapor. If bending compresses or clogs the space, performance will be partially compromised, making the flexible keel assembly a crucial design consideration. Example 3

[0038] The upper surface of the heat-conducting fixing block 5 contacts the processor 8 and absorbs the processor's heat, transferring it to the composite material metal mesh 5. The composite material metal mesh 5 then transfers the heat to the capillary wick 6. The capillary wick 6 then disperses the heat to the underlying composite material metal mesh layer 2, which then dissipates the heat. This effectively dissipates the heat from the processor. Figure 1 The middle 7 is the motherboard. Example 4

[0039] The foldable products that can be used by the present invention may be mobile phones, laptop computers, servers, wearable products, etc., and may be folded 20% or 30% of the way.

[0040] The shape and size of the flexible keel assembly can be optimized and adjusted to different shapes and structures, such as wave shape and rotation shape. No matter how it is optimized and adjusted, its function remains unchanged.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
