[0002] An embedded chassis is usually a smaller chassis that can be embedded in other devices, such as motherboards, routers, firewalls, industrial control systems, etc. An embedded chassis is a chassis designed specifically for embedding in other devices. Its shape is usually determined by the embedded device and varies in size. It is widely used in devices that need to run for a long time, such as industrial control systems, automotive electronics, medical equipment, game consoles and other embedded industrial fields. A large number of electronic components are usually integrated inside the embedded chassis. These components will generate a lot of heat during operation. In order to ensure the long-term stable operation of the equipment, this heat must be effectively dissipated. Some embedded chassis will be equipped with cooling fans to enhance the heat dissipation effect. These fans are usually installed on the side or rear of the chassis. By inhaling external low-temperature air, passing through the heating elements inside the chassis, the hot air is discharged outside the chassis. The speed and wind force of the fan can be intelligently adjusted according to the temperature inside the chassis to achieve the best heat dissipation effect.
