Fan rotating speed controlling method and switchboard equipment

Abstract

The utility model relates to system heat dissipation processing technology of table type network equipment, and discloses a fan rotating speed controlling method. According to the fan rotating speed controlling method, heat dissipation is conducted on a system according to needs, and noise is reasonably controlled while requirements of heat dissipation are met. The method includes the following steps of calculating an actual working temperature value of a power source module, making sure a duty ratio of fan rotating speed needed by heat dissipation of the power source module according to the actual working temperature value of the power source module and a set temperature value when the power source module works stably, and controlling a fan module to rotate in the rotating speed. Besides, the invention further discloses switchboard equipment. The fan rotating speed controlling method is applicable to system heat dissipation on the network equipment.

Description

technical field [0001] The invention relates to a system heat dissipation processing technology of a desktop network device, in particular to a fan speed control technology in the network device. Background technique [0002] As an access device in various networks, an Ethernet switch is an important support to ensure the performance of the entire network. With the development of technology, higher requirements are put forward for the overall performance and reliability of Ethernet switches. Not only are Ethernet switches required to be able to forward between ports; Ethernet switches can also withstand the test of various external environments, such as: harsh climate environment, mechanical environment, EMC, etc. As the port density of Ethernet switches is getting higher and higher, the rate has also been increased from the previous 10M and 100M to 1G and 10G, and the function has also changed from the previous simple layer-2 forwarding to now being able to handle some lay...

Problems solved by technology

[0004] 1. Add a heat sink to the main heating chip to dissipate heat; this method is suitable for Layer 2 switches with single functions and low port density, but the heat dissipation effect cannot be guaranteed, and problems such as crashes may still occur in high-temperature and high-humidity environments;

[0005] 2. On the basis of method 1, add a certain number of fans for forced cooling; this method is applicable to most 1G, 10G high-density port two-layer and three-layer switches, but in order to ensure the cooling effect, high-speed fans are usually used , which will cause the noise of the whole machine to increase, and the noise test will not meet the standard
