Description

Technical Field

[0001] This utility model relates to the field of heat dissipation materials technology, and in particular to a wear-resistant and shielded graphite heat sink that prevents displacement. Background Technology

[0002] Graphite heat sinks are mainly used in electronic equipment, communication equipment, medical instruments and other products that have high requirements for heat dissipation performance, stability and electromagnetic compatibility. Graphite heat sinks, also known as thermally conductive graphite sheets, are a new type of thermally conductive and heat dissipation material that can effectively solve the heat dissipation problem during equipment operation, while improving the reliability and safety of the equipment.

[0003] With the rapid development of electronic technology, the integration of electronic devices is constantly increasing, and the power density is continuously growing. This causes a large amount of heat to be generated during the operation of the equipment. If the heat cannot be dissipated in time, it will lead to a decline in equipment performance, a shortened lifespan, or even failure. Graphite heat sinks are widely used in the field of heat dissipation due to their excellent thermal conductivity. However, existing graphite heat sinks have many shortcomings. During the operation of the equipment, vibration and temperature changes will occur. Traditional graphite heat sinks, due to the lack of a reliable anti-displacement design, are prone to displacement under the influence of these factors. For example, in some industrial equipment with large vibrations, the graphite heat sink may gradually shift from its original position, resulting in uneven heat dissipation and even overheating of the equipment. To address these issues, we propose an anti-displacement wear-resistant shielded graphite heat sink. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant, shielded graphite heat sink that prevents displacement, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wear-resistant shielded graphite heat sink with anti-displacement capability includes a graphite heat sink substrate and a mounting base. The upper surface of the mounting base is fixedly connected with multiple positioning posts and has multiple slots. The outer surface of the graphite heat sink substrate is fixedly connected with multiple edge buckles and has multiple positioning holes that are adapted to the positioning posts.

[0007] In a further embodiment, an electromagnetic shielding layer is connected to the outer surface of the graphite heat dissipation substrate, and a wear-resistant coating is connected to the outer surface of the electromagnetic shielding layer.

[0008] In a further embodiment, a grounding pin is connected to the outer surface of the electromagnetic shielding layer.

[0009] In a further embodiment, the outer surface of the wear-resistant coating is connected with a plurality of bumps and recesses.

[0010] In a further embodiment, the bottom surface of the graphite heat dissipation substrate is provided with multiple grooves.

[0011] In a further embodiment, each of the edge buckles has a fixedly connected buckle protrusion on its outer surface, and the edge buckle is adapted to the buckle groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This anti-displacement wear-resistant shielded graphite heat sink achieves multi-directional anti-displacement functionality through the design of positioning posts, slots, edge clips, and positioning holes. The positioning posts and positioning holes work together to accurately determine the position of the heat sink during installation, while the edge clips and slots securely fix the heat sink in the installation position, preventing it from shifting due to vibration or other factors during equipment operation. The shape and size of the clips are carefully designed to ensure stable fixing force without negatively impacting the heat dissipation performance of the heat sink. This ensures that the heat sink and the heat-generating element always maintain good contact, improving heat dissipation efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4In this utility model, a wear-resistant shielded graphite heat sink with anti-displacement capability includes a graphite heat sink substrate 1 and a mounting base 2. Multiple positioning posts 4 are fixedly connected to the upper surface of the mounting base 2, and multiple slots 3 are formed on the upper surface of the mounting base 2. Multiple edge clips 6 are fixedly connected to the outer surface of the graphite heat sink substrate 1, and multiple positioning holes 5 that match the positioning posts 4 are formed on the outer surface of the graphite heat sink substrate 1. The graphite heat sink substrate 1 needs to be adjusted according to actual heat dissipation requirements, generally consisting of 5-20 layers, with the total thickness controlled between 0.1-0.5 mm, while ensuring… While providing excellent heat dissipation performance, it also maintains the thinness and lightness of the heat sink, making it suitable for various electronic devices with high space requirements. The edge clip 6 is made of high-strength, high-temperature resistant engineering plastics, such as polyetheretherketone (PEEK) or polyphenylene sulfide (PPS). The positioning post 4, the slot 3, the edge clip 6, and the positioning hole 5 together constitute the basic structure to prevent displacement. The positioning post 4 and the positioning hole 5 cooperate to position the heat sink during installation, ensuring that it can be accurately placed. The edge clip 6 and the slot 3 cooperate to fix the heat sink in the installation position and prevent it from shifting during use.

[0023] An electromagnetic shielding layer 7 is connected to the outer surface of the graphite heat sink substrate 1. A wear-resistant coating 9 is connected to the outer surface of the electromagnetic shielding layer 7. The electromagnetic shielding layer 7 can be made of copper foil, aluminum foil, or electromagnetic shielding fabric, possessing good conductivity and high electromagnetic shielding effectiveness. It generally provides good shielding against both low-frequency and high-frequency electromagnetic interference. Its thickness is selected according to actual shielding requirements; the thickness of copper foil or aluminum foil is generally 0.01-0.05 mm, and the thickness of electromagnetic shielding fabric is 0.05-0.2 mm. A grounding pin 8 is connected to the outer surface of the electromagnetic shielding layer 7. This pin is made of a highly conductive metal material, such as copper or silver, and is tightly connected to the electromagnetic shielding layer 7 by welding or riveting. It guides the generated electromagnetic radiation to the ground, thus achieving a good electromagnetic shielding effect. The wear-resistant coating 9 is made of a material with high hardness, good wear resistance, and chemical stability, such as titanium nitride, silicon carbide, or diamond-like carbon. The electromagnetic shielding layer 7 can shield electromagnetic interference and protect the normal operation of electronic equipment. The wear-resistant coating 9 enhances the wear resistance of the heat sink and extends its service life.

[0024] The outer surface of the wear-resistant coating 9 is connected with multiple bumps 10, which can increase the roughness of the coating surface and improve its friction with the surrounding environment, thereby further reducing the possibility of the heat sink sliding or shifting when subjected to external force. The bottom surface of the graphite heat dissipation substrate 1 is provided with multiple grooves 11, which can be filled with thermal grease to improve the heat dissipation effect. Each edge buckle 6 is fixedly connected with a buckle protrusion 12 on its outer surface, and the edge buckle 6 is adapted to the buckle groove 3, which enhances the connection strength between the edge buckle 6 and the buckle groove 3 and further improves the anti-shifting effect. When the edge buckle 6 is snapped into the buckle groove 3, the buckle protrusion 12 can be tightly snapped into the buckle groove 3, making it difficult for the edge buckle 6 to fall out, and ensuring that the heat sink is more stable during use.

[0025] The working principle of this utility model is as follows:

[0026] During assembly, the mounting base 2 is equipped with corresponding positioning posts 4 and slots 3 at the mounting locations of electronic devices. During installation, the positioning holes 5 on the graphite heat sink 1 are fitted onto the positioning posts 4, and the edge clips 6 are inserted into the corresponding slots 3. Once the graphite heat sink 1 is installed on the positioning posts 4, the edge clips 6 will engage with the pre-designed slots 3, firmly securing the graphite heat sink 1. This prevents it from shifting due to vibration, temperature changes, or other factors during equipment operation. Furthermore, it ensures proper positioning between the graphite heat sink 1 and the mounting base 2 during installation. Fill the groove 11 with an appropriate amount of thermal grease. Thermal grease is commonly known as heat dissipation paste. It is a thermally conductive silicone grease compound made by adding heat-resistant and thermally conductive materials as the main raw material. The electromagnetic shielding layer 7 connected to the outer surface of the graphite heat dissipation substrate 1 can effectively shield the surrounding electromagnetic interference, protect the electronic equipment from the influence of electromagnetic radiation, and improve the stability and reliability of the equipment. The wear-resistant coating 9 enhances the wear resistance of the graphite heat dissipation substrate 1 and reduces the damage caused by friction, scratches and other factors during use.
