Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, in particular to a graphite composite aerogel heat sink. Background Art

[0002] With the continuous improvement of the performance of electronic devices, the demand for heat dissipation technology is also increasing. Modern electronic devices generate a lot of heat during operation, especially under high power density conditions. Heat dissipation becomes an important factor affecting the performance and life of the equipment. Therefore, the development and application of high-efficiency heat dissipation materials have attracted much attention. Although traditional metal heat sinks (such as aluminum, copper, etc.) have good thermal conductivity, they are dense and heavy, and are not suitable for application scenarios that require lightweight and flexibility. At the same time, with the integration and miniaturization of electronic devices, heat dissipation materials are required to have better thermal conductivity and lower weight.

[0003] As a new type of thermal conductive material, graphite-based materials have gradually attracted the attention of scientific research and industry due to their excellent thermal conductivity, lightness and designability. Aerogel, as an ultra-light and ultra-porous material, has become an important choice for weight reduction materials due to its low density and high porosity. Laptop computers, tablets, mobile phones and other consumer electronic products usually use heat sinks for heat dissipation. In actual use, existing heat sinks are usually fixed in shape and need to be customized for electronic products of different sizes and types. The time cycle is relatively long and it is not possible to quickly adapt to different types of electronic products. The utility model proposes a graphite composite aerogel heat sink to meet the demand for rapid adaptation to the heat dissipation of different types of electronic products. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a graphite composite aerogel heat sink to solve the problem that existing heat sinks are usually fixed in shape and cannot be quickly adapted to dissipate heat from different types of electronic products.

[0005] Based on the above purpose, the utility model provides a graphite composite aerogel heat sink, including a heat sink assembly, which is formed by multiple groups of heat sink bodies connected to each other. The heat sink bodies can be folded with each other, and split seams are provided between the heat sink bodies.

[0006] Preferably, an aerogel layer is provided in the center of the heat sink body, and the aerogel layer is made of aerogel material. Graphite layers are provided at both ends of the aerogel layer, and the graphite layers are made of graphite material.

[0007] Preferably, a plurality of groups of heat-conducting spacers are provided in the heat sink body, the plurality of groups of heat-conducting spacers penetrate the graphite layer, and the heat-conducting spacers are of a cavity structure.

[0008] Preferably, expansion joints are provided on both side surfaces of the heat sink body.

[0009] Preferably, the graphite layer is composite-woven with reinforcing fibers, and the reinforcing fibers are made of carbon fiber.

[0010] Beneficial effects of the utility model:

[0011] 1. By interconnecting multiple groups of heat sink bodies, a foldable structure is achieved, which is convenient for flexible adjustment according to the shape and needs of different devices. At the same time, the split seams between the heat sink bodies allow each group of heat sinks to be easily separated, increasing the applicability and service life of the product. At the same time, the graphite composite aerogel material has excellent thermal conductivity and lightweight properties. It can reduce the burden on the equipment while ensuring efficient heat dissipation. It is suitable for the heat dissipation needs of modern electronic equipment and improves the convenience, practicality and reliability of the heat sink.

[0012] 2. An aerogel layer is set in the inner center of the heat sink body. By utilizing the excellent thermal insulation and ultra-lightweight properties of aerogel, the weight of the heat sink body is significantly reduced while effectively isolating heat conduction. The aerogel material can block unnecessary heat conduction and reduce heat flow resistance through its porous structure, ensuring the overall weight of the heat dissipation system.

[0013] 3. The graphite layers at both ends of the aerogel layer are high thermal conductivity materials. Graphite has an extremely high thermal conductivity coefficient and can quickly transfer the heat isolated by the aerogel layer to the outer surface of the heat sink, allowing the heat to diffuse rapidly and be conducted to the external environment. The graphite layer can greatly improve the thermal conductivity of the heat sink, while ensuring the stability and durability of the heat sink in high temperature environments, which helps to extend the service life of the equipment and is suitable for electronic equipment with high lightweight requirements.

[0014] 4. Multiple sets of thermal spacers are installed inside the heat sink body. The thermal spacers penetrate the graphite layer structure and have a cavity structure, forming multiple independent heat conduction paths. The thermal spacers can further optimize the heat conduction process, evenly distribute the heat and quickly discharge it from the inside of the device, avoiding localized heat accumulation and improving the overall performance of the cooling system. The cavity structure of the thermal spacers reduces weight, improves thermal conductivity, and enables heat to be diffused in a more efficient manner.

[0015] 5. Carbon fiber reinforced fibers are woven inside the graphite layer, which significantly improves the mechanical strength of the heat sink. Carbon fiber materials have high strength and good tensile strength, which makes the heat sink have stronger bending resistance and impact resistance while maintaining lightweight, ensuring that the heat sink can still maintain stable operation in complex environments and is not easily deformed or damaged. The addition of reinforced fibers enhances the durability of the heat sink, so that it can still maintain good performance during long-term use, making the heat sink have excellent heat dissipation effect, while taking into account lightweight and structural strength. It is suitable for electronic equipment cooling systems with high performance, lightweight and durability requirements.

[0016] 6. The expansion joint allows the heat sink to deform flexibly under the influence of external forces, preventing structural damage and improving the reliability and fatigue resistance of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1-4 As shown, a graphite composite aerogel heat sink includes a heat sink assembly 1, which is formed by a plurality of heat sink bodies 3 connected to each other. The heat sink bodies 3 can be folded together, and split seams 2 are provided between the heat sink bodies 3;

[0026] By interconnecting multiple groups of heat sink bodies 3, a foldable structure is achieved, which is convenient for flexible adjustment according to the shape and needs of different devices. At the same time, the split seams 2 between the heat sink bodies 3 enable each group of heat sinks to be easily separated, which is convenient for maintenance and replacement, and increases the applicability and service life of the product. At the same time, the graphite composite aerogel material has excellent thermal conductivity and lightweight properties, which can reduce the burden on the equipment while ensuring efficient heat dissipation. It is suitable for the heat dissipation needs of modern electronic equipment and improves the convenience, practicality and reliability of the heat sink.

[0027] like Figure 2-Figure 4 As shown, an aerogel layer 5 is provided in the center of the heat sink body 3. The aerogel layer 5 is made of aerogel material. Graphite layers 6 are provided at both ends of the aerogel layer 5. The graphite layers 6 are made of graphite material. Multiple groups of heat-conducting spacers 4 are provided in the heat sink body 3. The multiple groups of heat-conducting spacers 4 pass through the graphite layer 6. The heat-conducting spacers 4 have a cavity structure. Reinforcement fibers are compositely woven in the graphite layer 6. The reinforcement fibers are made of carbon fiber material.

[0028] An aerogel layer 5 is provided at the center of the heat sink body 3. Utilizing the excellent thermal insulation and ultra-lightweight properties of aerogel, the aerogel effectively isolates heat conduction while significantly reducing the weight of the heat sink body 3. The aerogel material blocks unnecessary heat conduction and, through its porous structure, reduces heat flow resistance, ensuring the overall weight of the heat dissipation system.

[0029] Secondly, the graphite layers 6 at both ends of the aerogel layer 5 are made of highly thermally conductive materials. Graphite has an extremely high thermal conductivity coefficient and can quickly transfer the heat isolated by the aerogel layer 5 to the outer surface of the heat sink, allowing the heat to diffuse rapidly and be conducted to the external environment. The graphite layer 6 can significantly improve the thermal conductivity of the heat sink, while ensuring the stability and durability of the heat sink in high-temperature environments, helping to extend the service life of the device, and is suitable for electronic devices with high lightweight requirements.

[0030] At the same time, multiple groups of heat-conducting spacers 4 are arranged inside the heat sink body 3. The heat-conducting spacers 4 penetrate the structure of the graphite layer 6. The heat-conducting spacers 4 have a cavity structure, forming multiple independent heat conduction paths. The heat-conducting spacers 4 can further optimize the heat conduction process, evenly distribute the heat and quickly discharge it from the inside of the device, avoiding local heat accumulation and improving the overall performance of the heat dissipation system. The heat-conducting spacers 4 with a cavity structure reduce weight and improve thermal conductivity, allowing heat to be diffused in a more efficient manner.

[0031] Finally, carbon fiber reinforced fibers are woven inside the graphite layer 6, which significantly improves the mechanical strength of the heat sink. The carbon fiber material has high strength and good tensile strength, which makes the heat sink have stronger bending resistance and impact resistance while maintaining lightweight, ensuring that the heat sink can still maintain stable operation in complex environments and is not easily deformed or damaged. The addition of reinforced fibers enhances the durability of the heat sink, so that it can still maintain good performance during long-term use, making the heat sink have excellent heat dissipation effect, while taking into account lightweight and structural strength, and is suitable for electronic equipment cooling systems with high performance, lightweight and durability requirements.

[0032] like Figure 3 and Figure 4 As shown, expansion joints 7 are provided on both sides of the surface of the heat sink body 3;

[0033] The expansion joint 7 enables the heat sink to deform flexibly under the influence of external forces, thereby preventing structural damage and improving the reliability and fatigue resistance of the product.
