Example Embodiment

[0029] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.

[0030] In order to achieve the following purposes: when using an adjustable-speed fan to dissipate heat, it can prevent the fan speed from oscillating, and can reduce system noise and power consumption, especially when a fan fails, other fans can coordinate the speed, and can be based on user needs , Can flexibly switch the fan speed to control the device in a constant temperature set by the user. The following solutions are now provided, as follows:

[0031] figure 1 It is a flowchart of a method for controlling the speed of a fan in an electronic device according to an embodiment of the present invention. Such as figure 1 As shown, the method includes: step S102 to step S106,

Abstract

A method and device for controlling a rotating speed of a fan in an electronic device. The method comprises the following steps: obtaining a first temperature value of a designated temperature collecting point in the electronic device at a current rotating speed of the fan (S102), obtaining a change value of the first temperature value in a first preset time period (S104); and adjusting the rotating speed of the fan while the change value is greater than a first preset threshold (S106). By the method and device mentioned above, the technical problem of rotating speed rebound or vibration can be solved during the radiating process of a speed adjustable fan, and thus the steady running of the fan is ensured in a certain degree and the service life of the fan is prolonged.

Description

technical field [0001] The invention relates to the field of heat dissipation, in particular to a method and device for controlling the rotational speed of a fan in electronic equipment. Background technique [0002] With the improvement of the integration of electronic, communication and electrical equipment, the power consumption of the equipment is also increasing, and at the same time, the heat generation of the equipment is also increasing. The electronic components in the equipment, especially the key chips, have strict requirements on the temperature. If the temperature is too high, it will cause business abnormalities and even damage the equipment. Therefore, the heat dissipation and cooling of the equipment has become an important concern. At present, the main heat dissipation method of electronic equipment is to cool down through fans. In order to meet the heat dissipation and cooling requirements of the system, multiple high-power fans are often configured. The ...
