Embodiment Construction

[0030] In order to make the above and other objectives, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below, which are described in detail below in conjunction with the accompanying drawings.

[0031] Please refer first figure 1 , figure 1 It is a system architecture diagram of the fan control system of the present invention.

[0032] The fan control system 10 of the present invention is used in an electronic device 1 to control the vibration of the swing fan device 20 in the electronic device 1 so that the swing fan device 20 can cool the electronic device 1. The electronic device 1 can be a notebook computer, a smart phone or a tablet computer, but the invention is not limited thereto.

[0033] The swing fan device 20 includes an actuation module 21 and a thin film swing 22. The flap fan device 20 may be a piezoelectric fan or an electromagnetic fan. The actuating module 21 is connected to the diaphr...

Abstract

A fan control system and a fan controlling method thereof are disclosed. The fan control system is used to an electronic apparatus for controlling an air pump fan device. The fan controlling method includes following steps: setting a plurality of vibrating working periods of the air pump fan device; setting a plurality of vibrating frequencies of the air pump fan device, wherein each vibrating frequency has a different vibrating frequency value; detecting a temperature of the electronic apparatus; determining whether the temperature of the electronic apparatus exceeding a first setting temperature; and if yes, controlling the air pump fan device to vibrate according to the plurality of vibrating frequencies during the plurality of vibrating working periods, wherein adjacent vibrating working periods of the plurality of vibrating working periods correspond to different vibrating frequency values.

Description

Technical field [0001] The invention relates to a fan control system and a fan control method thereof, in particular to a fan control system and a fan control method thereof that can prevent the fan from continuously vibrating at a fixed frequency. Background technique [0002] With the advancement of science and technology, today's electronic products are developing towards the goal of lightness, thinness and shortness. On the other hand, when electronic products are operating, they must be accompanied by heat generation. Without proper heat dissipation system, this electronic product will be damaged due to temperature rise. Traditional heat dissipation systems mainly use rotary fan blades to dissipate heat. However, for thin and light electronic products, these electronic products are not suitable for installing rotary fan blade fans with a rotating shaft. Therefore, the current technology has developed a smaller swing-blade fan. [0003] The swing plate fan can be divided int...
