Problems solved by technology

However, if the step size is too small, the heat dissipation efficiency will be reduced, and when the ambient temperature fluctuates slightly, it will cause the fan speed to rebound or oscillate.
This hot and cold heat dissipation is not conducive to the safe operation of the equipment, and the noise will be louder
[0005] For the above-mentioned problems in related technologies, no effective solution has been proposed yet

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 ...
