The router motherboard radiator mainly achieves efficient heat dissipation through the following ways to ensure the stable operation of the router:
1. Heat dissipation hole design
Many routers have small holes evenly distributed around the body. The design of these heat dissipation holes helps to achieve good heat dissipation. When the router is running, the internal heating components will generate heat, which will increase the temperature of the surrounding air. The hot air flows upward through the heat dissipation holes, while the cold air outside will enter the router from the heat dissipation holes below, forming an air circulation and continuously taking away the heat. The size, shape and layout of the heat dissipation holes will also affect the heat dissipation effect. Larger heat dissipation holes can make air circulation smoother, but at the same time, it is necessary to consider preventing dust and other impurities from entering the router.
2. Application of heat dissipation fins
Some routers are equipped with heat dissipation fins near the motherboard. Heat dissipation fins are usually made of metal materials, such as aluminum or copper, which have good thermal conductivity. The heat sink fins are in close contact with the heating element of the router, which can quickly transfer heat to the fins, and then dissipate the heat by increasing the contact area between the fins and the air. In order to ensure stability under high-load operation, high-performance home routers will use large-area heat sink fins to assist in heat dissipation.
3. Use of heat sink pads
The heat sink pad is a heat dissipation component located inside the router, usually made of thermal conductive materials, such as silicone pads. Its function is to fill the gap between the heating element and the router shell so that the heat can be better transferred to the shell, and then dissipated through the heat dissipation holes on the shell.
4. Built-in fan heat dissipation
Some high-end routers use built-in fans for active heat dissipation. The built-in fan can form forced convection inside the router, greatly increasing the air circulation speed, thereby taking away the heat more quickly. This heat dissipation method is very effective and can maintain a low temperature even when the router is running at high load. Enterprise-level routers or high-performance routers for gamers are usually equipped with powerful built-in fans to meet the needs of long-term and high-load use. These fans usually have a high speed and a large air volume, which can effectively reduce the temperature of the router and ensure the stable operation of the network.
5. External cooling assistance
In addition to the router's own cooling method, users can also add external fans to the router for auxiliary cooling as needed. The external fan can blow directly at the router to speed up the air flow around the router and improve the cooling effect. This method is relatively simple and easy. Users can buy some small USB fans online and place them next to the router, or fix the fans above the router through some brackets so that the fans blow at the router's cooling holes. However, it is necessary to pay attention to the noise of the fan and ensure that the placement of the fan does not hinder the normal cooling of the router.
6. Optimize the placement and regular cleaning
The placement of the router also has a great impact on heat dissipation. The router should be placed in a well-ventilated and open space as much as possible, and avoid placing it in a small space, drawer or cabinet, otherwise it will affect the air circulation and cause poor heat dissipation. In addition, dust is an important factor affecting the heat dissipation of the router. After long-term use, a lot of dust will accumulate in the cooling holes and inside of the router. This dust will block the cooling holes and hinder the air circulation, thereby affecting the heat dissipation effect. Therefore, it is very necessary to clean the dust of the router regularly.
The router motherboard radiator achieves efficient heat dissipation through a variety of methods to ensure the stable operation of the router. When using the router, users can also take some auxiliary measures to improve the heat dissipation effect and extend the service life of the router.
