Description

Technical Field

[0002] A switch is a network device used to forward electrical signals. With the development of the communications industry and the advancement of informatization of the national economy, the market for network switches has been steadily increasing. It has the characteristics of high cost performance, high flexibility, relative simplicity and easy implementation. Ethernet technology has become the most important LAN networking technology today, and network switches have become the most popular switches. Existing switches will generate a lot of heat during use. If the ambient temperature of the switch is high, it is easy for the switch to work poorly.

[0003] The patent with application number 202322172098.6 discloses a heat dissipation device for a network equipment switch, including a heat dissipation shell, the heat dissipation shell is fixedly connected to the switch, and also includes a heat dissipation mechanism and a cooling mechanism; the heat dissipation mechanism includes a first fixed block fixedly connected to the heat dissipation shell, the first fixed block is rotatably connected to the first screw rod, the first screw rod is threadedly connected to the first slider slidably connected to the inner wall of the shell, the middle part of the first slider is rotatably connected to the rotating shaft, and the rotating shaft is fixedly connected to the alcohol cotton strip; the cooling mechanism includes a second fixed block fixedly connected to the heat dissipation shell, the second fixed block is rotatably connected to the second screw rod, the second screw rod is threadedly connected to the second slider slidably connected to the inner wall of the shell, and the second slider is fixedly connected to the alcohol tank.

[0004] The above technical solution uses a rotating shaft with an alcohol cotton strip, a first motor and a second motor, so that the alcohol cotton strip on the rotating shaft is dipped in alcohol to dissipate the heat of the switch. There is a safety hazard due to the volatilization of alcohol during use, and the first motor and the second motor will generate heat that affects the heat dissipation effect when working. At the same time, since the inside of the switch is in a closed state, the heat is difficult to be transmitted to the rotating shaft, and the contact area between the rotating shaft and the surface of the switch is small during the movement, and the heat dissipation effect is poor.
