Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch casing which is convenient for cleaning dust at an air inlet. Background Art

[0002] A switch is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. In a broad sense, a switch is a device that implements the information exchange function in a communication system. The most common switch is the Ethernet switch, and other common switches include telephone voice switches, fiber optic switches, etc.

[0003] From the hardware structure point of view, the switch is composed of the chassis, power supply, fan, backplane, management engine, system controller, switching module, line card and other components. Since the switch generates heat inside the chassis when it is working, it needs to be discharged to the outside through the fan. The external air is sucked in through the air inlet at the bottom of the chassis and then discharged through the air outlet on the side. After long-term operation, the air inlet at the bottom will absorb a lot of dust, hair and other debris. These debris gather at the air inlet and stick to each other to form a "net" structure, blocking the air inlet, which will affect the normal heat dissipation of the switch, causing the internal components to overheat and reduce the working efficiency. In severe cases, the components may be burned. Therefore, it is necessary to design a structure to clean up these debris in a timely and efficient manner to improve the heat dissipation efficiency of the switch. Utility Model Content
