Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the specific embodiment of the present invention is described in further detail:

[0024] As shown in FIG. 2 , it is a flowchart of a fan control method according to an embodiment of the present invention. It mainly includes the following steps:

[0025] Step 201, divide the fans in the fan system into multiple fan groups. All the fans in the fan system are grouped into multiple different fan groups, each fan group includes at least one fan, and the number of fans in each fan group may be the same or different. Then set the speed regulation level of the fan system according to the number of fan groups obtained from the division. The speed regulation level is generally set to be greater than or equal to the number of fan groups, and of course it can also be set to be smaller than the number of fan groups. But for the preferred embodiment of the present invention, the speed level of the fan system is set to b...

Abstract

The invention discloses a fan controlling means, which is used for a fan system comprising at least two fan sets and used for making one or more steps of speed regulation on the fan system, wherein, each of the fan sets at least comprises a fan and comprises the following steps: a fan set is selected to be regulated from the fan system; the speed of the fan set is regulated in a gradual way when two or more speed steps need to be regulated. The invention additionally provides a fan controlling device, which can cause the fan to effectively reduce the current shock during the operation, avoid the influence on the power supply system, reduce the noise and save the energy.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a fan control method and device. Background technique [0002] With the vigorous development of the electronic industry, electronic equipment has entered the research and development direction of multi-function and high performance. In pursuit of multi-functional and high-performance electronic equipment, the integration density of electronic components is constantly increasing, and the working power is constantly increasing. Electronic equipment generates heat when it is working. In order to prevent various problems caused by overheating of the electronic equipment, a cooling device is provided on the electronic equipment to reduce the temperature of the electronic equipment during operation. Because fans have the characteristics of small size and good heat dissipation effect, electronic equipment usually uses fans to dissipate heat, and in order to meet heat dissip...
