Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a heat dissipation structure for a switch. Background Art

[0002] A switch is a network device for forwarding electrical signals. It mainly provides an exclusive electrical signal path for any two network nodes accessing the switch. The core of the switch heat dissipation system is realized through a fan module. These fans are usually installed on the back of the device, and the air intake is from the front and the air outlet is from the back, taking out the heat generated by the MPU, LPU, and SFU single boards inside the frame to ensure that the frame works within the normal temperature range.

[0003] After retrieval, a silent fan structure for switch heat dissipation disclosed in the publication number "CN220979941U" includes a special-shaped aluminum plate, which is composed of a rectangular aluminum plate and a square aluminum plate. The lower left end of the rectangular aluminum plate and the upper right end of the square aluminum plate are welded and fixed staggeredly by two to three centimeters. A number of strip-shaped hollow grooves are arranged at equal intervals on the upper surfaces of the rectangular aluminum plate and the square aluminum plate. A circular groove is arranged at the center of the hollow groove area on the upper surface of the square aluminum plate. This structure constitutes a reasonable air duct through the special-shaped heat sink. At the same time, a shock absorption component is arranged between the connection of the silent fan and the heat sink, and the silent fan itself is designed with a stable component, solving the problem of relatively large noise of the switch fan in the prior art.

[0004] Although this patent can reduce the noise of the fan and reduce the eccentricity phenomenon generated after long-term use of the fan, this patent only uses reinforcing ribs for welding to reinforce the anti-offset shaft. During the welding process, problems such as missed welding or insecure welding of the reinforcing ribs will occur, which will make the use effect of the reinforcing ribs worse, resulting in the eccentricity phenomenon of the fan still existing after long-term use. And when reducing the fan noise, springs and gaskets are used to reduce the vibration transmitted from the fan bracket. However, the vibration frequencies transmitted by the fan bracket at different times are different. When the vibration frequency is too large, the spring may be damaged under the huge vibration, thus affecting the silent effect of the fan. Therefore, it is necessary to improve this.
