Abstract

The invention discloses a heat dissipation and electromagnetic interference prevention device for network equipment, which comprises a shell, a plurality of placement bins are arranged in the shell, a heat dissipation plate is arranged on one side of the shell, a plurality of first heat dissipation holes are formed in the heat dissipation plate, and sliding grooves are formed between the heat dissipation plate and the placement bins; an elastic piece is arranged at one end in the sliding groove, an air bag is arranged at the other end in the sliding groove, a sliding block is arranged between the elastic piece and the air bag, a plurality of second heat dissipation holes are formed in the sliding block, and the second heat dissipation holes are communicated with or staggered with the first heat dissipation holes along with sliding of the sliding block. The device not only meets the conventional working requirements of the network equipment, but also can divide each working area, realize fixed-point efficient cooling and ensure the heat dissipation efficiency and heat dissipation effect of the device, and meanwhile, the device also can judge whether the device is influenced by electromagnetic interference or not according to the displacement difference detected by each displacement sensor, so that the working efficiency of the device is improved. Therefore, electromagnetic interference can be prevented, and the efficient heat dissipation performance of the device can be continuously realized. The invention is applied to the technical field of network equipment.

Description

technical field [0001] The invention relates to the technical field of network equipment, in particular to a heat dissipation and electromagnetic interference prevention device for network equipment. Background technique [0002] Network devices and components are physical entities connected to a network, and there are many and growing types of them. Basic network devices are: computers, hubs, switches, bridges, routers, gateways, network interface cards, wireless access points, printers and modems, fiber optic transceivers, fiber optic cables, etc. EMI is electrical noise that interferes with the cable signal and degrades signal integrity. EMI is typically generated by sources of electromagnetic radiation such as motors and machines. Electromagnetic interference is an electromagnetic phenomenon that people have discovered a long time ago. It was discovered almost at the same time as the electromagnetic effect. In 1881, the British scientist Heaviside published an article "...

Problems solved by technology

However, this invention can only dissipate heat through the heat dissipation element, the heat dissipation efficiency is low, and the anti-electromagnetic interference effect is poor

[0004] In actual use, the anti-electromagnetic interference needs to completely isolate the internal components from the outside world, so as to effectively prevent the influence of electromagnetic interference on the internal components. However, when the network equipment is completely isolated from the outside world, the electrical components inside the network equipment The heat dissipation effect of the components will be reduced synchronously, resulting in electrical overheating and damage
