Description

Technical Field

[0001] The utility model relates to the field of heat sinks, in particular to a router heat sink. Background Art

[0002] A router is a device that connects local area networks and wide area networks in the Internet. It will automatically select and set the route according to the channel conditions, send signals in the best path in sequence. The router is the hub of the interconnected network. At present, routers have been widely used in all walks of life, and various products of different grades have become the main force for realizing internal connections of various backbone networks, interconnections between backbone networks, and interconnections between backbone networks and the Internet. Various electronic components are installed inside the router, and the heat generated by the electronic components usually needs to be discharged through the router heat sink. The router heat sink is installed on the router and is an important component for helping to reduce the device temperature.

[0003] However, in actual use, there are still some disadvantages: when the existing router is working, the heat sink is fixed by screws. The heat sink is fixed to the outer shell of the router by screws. The working environment of the router is external. Therefore, once there is humid air around the router, the humid air adheres to the surface of the bolts, and over time, the surface of the screws will rust, which will cause the connection between the screws to become tight, making it inconvenient to disassemble the heat sink. Tools such as screwdrivers are required for installation and disassembly, which is very troublesome. Therefore, the heat sink fixed by screws has the problem of inconvenient installation and disassembly. When the existing router is working, the heat sink is directly installed on the outer shell of the router by screws, and the components that generate heat in the router are the internal electronic components. The electronic components are installed inside the router, and the heat sink is installed outside the router. The electronic components usually do not directly contact the heat sink. Therefore, when the heat sink dissipates heat, the heat generated by the electronic components will not be directly discharged through the heat sink, but the heat generated by the electronic components accumulates on the outer shell of the router, is transferred to the heat sink through the outer shell of the router, and then the heat sink discharges the heat. Therefore, the heat sink does not directly contact the electronic components, resulting in the heat of the electronic components needing to be transferred through multiple layers to reach the heat sink, resulting in low heat dissipation efficiency and slow heat dissipation speed of the heat sink, and unable to quickly discharge the heat from the router. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art solutions, the utility model provides a router heat sink, which can effectively solve the technical problems that the existing heat sink is installed by screw fixation, making the heat sink inconvenient to install and disassemble, and the heat sink does not directly contact the electronic components inside the router, resulting in low heat dissipation efficiency and slow heat dissipation speed of the heat sink, and unable to quickly discharge the heat from the router.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: A router heat sink includes a bottom plate and side plates. The side plates are fixedly arranged on the side of the bottom plate. A connecting plate is fixedly arranged at the bottom of the bottom plate. The connecting plate is provided with a positioning portion and a clamping portion. A positioning groove is formed between the positioning portion and the clamping portion. A clamping groove is formed on the side of the clamping portion. A contact plate is fixedly arranged at the bottom of the bottom plate. The contact plate is perpendicular to the bottom plate. After installation, the contact plate is in contact with the electronic components inside the router. A plurality of heat dissipation fins are fixedly arranged on the top of the bottom plate. The plurality of heat dissipation fins are evenly arranged at equal intervals. The plurality of heat dissipation fins are used to absorb the heat generated by the electronic components inside the router.

[0006] Further, the heat dissipation fins are divided into a first fin, a second fin and a third fin. The first fin, the second fin and the third fin are respectively perpendicular to the bottom plate. The height of the first fin is less than the height of the second fin. The height of the second fin is less than the height of the third fin.

[0007] Further, side aluminum sheets are fixedly arranged on the top of the bottom plate. The side aluminum sheets are respectively parallel to the first fin, the second fin and the third fin.

[0008] Further, the surfaces of the side plates are respectively fixedly connected to the sides of the first fin, the second fin and the third fin.

[0009] Further, the bottom plate, the contact plate and the heat dissipation fins are all made of metal copper.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: For a router heat sink of the present utility model, by arranging a connecting plate at the bottom of the bottom plate and having a positioning groove formed by a positioning portion and a clamping portion, as well as the cooperation of the clamping groove, the effect of convenient disassembly of the heat sink is achieved. Compared with the traditional screw-fixed heat sink, the heat sink is convenient to install and disassemble. By arranging a contact plate and heat dissipation fins on the bottom plate, its heat dissipation efficiency is greatly improved. The contact plate is in contact with the electronic components inside the router. The heat generated when the electronic components work is transmitted to the bottom plate through the contact piece. The bottom plate transmits the heat to the heat dissipation fins. The heat dissipation fins absorb the heat transmitted by the bottom plate and are in contact with the air through the heat dissipation fins. The contact plate of the heat sink is directly in contact with the electronic components, greatly improving the heat dissipation speed and effectively avoiding the problem that heat cannot be quickly discharged from the router.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0020] As Figures 1-6 shown, a heat sink for a router includes a bottom plate 6 and a side plate 1. The side plate 1 is fixedly arranged on the side of the bottom plate 6. A connecting plate is fixedly arranged at the bottom of the bottom plate 6. The connecting plate is provided with a positioning portion 8 and an engaging portion 9. A positioning groove 10 is formed between the positioning portion 8 and the engaging portion 9. An engaging groove 11 is formed on the side of the engaging portion 9. A contact plate 7 is fixedly arranged at the bottom of the bottom plate 6. The contact plate 7 is perpendicular to the bottom plate 6. After installation, the contact plate 7 is in contact with the electronic component 13 inside the router 12. A plurality of heat dissipation fins are fixedly arranged on the top of the bottom plate 6. The plurality of heat dissipation fins are evenly arranged at equal intervals. The plurality of heat dissipation fins are used to absorb the heat generated by the electronic component 13 inside the router 12. The contact plate 7 is perpendicularly arranged with the bottom plate 6 and is in direct contact with the electronic component 13 inside the router 12 after installation, effectively increasing the heat conduction area and improving the heat transfer efficiency from the electronic component 13 to the heat sink, thereby dissipating the heat more quickly.

[0021] The heat dissipation fins are divided into a first fin 5, a second fin 4 and a third fin 3. The first fin 5, the second fin 4 and the third fin 3 are respectively perpendicular to the bottom plate 6. The height of the first fin 5 is less than the height of the second fin 4, and the height of the second fin 4 is less than the height of the third fin 3. Multi-level heat convection channels are formed by the heat dissipation fins with different heights, which helps to dissipate heat into the air faster. The equidistant arrangement of several heat dissipation fins also ensures the uniformity of heat distribution and improves the overall heat dissipation effect. A side aluminum sheet 2 is fixedly arranged on the top of the bottom plate 6, which further increases the heat dissipation area and can promote heat convection, thus accelerating the dissipation of heat. The side aluminum sheet 2 is parallel to the first fin 5, the second fin 4 and the third fin 3 respectively. The surfaces of the side plates 1 are fixedly connected to the sides of the first fin 5, the second fin 4 and the third fin 3 respectively. The bottom plate 6, the contact plate 7 and the heat dissipation fins are all made of metal copper. Copper has excellent thermal conductivity and can quickly conduct heat from the electronic component 13 to the heat sink, and dissipate it into the air through the heat dissipation fins and the side aluminum sheet 2, significantly improving the heat conduction efficiency and heat dissipation performance of the heat sink. An installation structure that mates with the positioning groove 10 and the engaging groove 11 is provided inside the router 12. A cavity and several electronic components 13 are provided inside the router 12. When the electronic components 13 work, heat is generated. The heat is transferred to the heat dissipation fins and the side aluminum sheet 2 through the contact plate 7 and the bottom plate 6, and can quickly discharge the heat outside the router 12.

[0022] For a router heat sink of this embodiment, by providing a connecting plate at the bottom of the bottom plate 6 and forming a positioning groove 10 with a positioning portion 8 and an engaging portion 9, as well as the cooperation of the engaging groove 11, the effect of convenient disassembly of the heat sink is achieved. Compared with the traditional screw-fixed heat sink, the heat sink is convenient to install and disassemble. By providing the contact plate 7 and the heat dissipation fins on the bottom plate 6, its heat dissipation efficiency is greatly improved. The contact plate 7 is in contact with the electronic component 13 inside the router 12. When the electronic component 13 works, the heat generated is transferred to the bottom plate 6 through the contact piece. The bottom plate 6 transfers the heat to the heat dissipation fins. The heat dissipation fins absorb the heat transferred by the bottom plate 6, and come into contact with the air through the heat dissipation fins to take away the heat and play a role in cooling, greatly improving the heat dissipation speed and effectively avoiding the problem that heat accumulation causes the heat to be unable to be discharged quickly.

[0023] In use, the heat sink is better installed on the surface of the router 12 by direct sliding. The side surface of the side plate 1 contacts the outer surface of the router 12. The heat sink can act as the top cover part of the router 12 housing, while the contact plate 7 contacts the electronic components 13 inside the router 12. The heat generated when the electronic components 13 work is transferred to the bottom plate 6 through the contact piece. The bottom plate 6 transfers the heat to the heat dissipation fins. The heat dissipation fins absorb the heat transferred by the bottom plate 6 and contact the air through the heat dissipation fins, thereby taking away the heat.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
