Problems solved by technology

Therefore, if a high-speed airflow is to be provided for a specific area (such as a certain part of an electronic component), the fan speed can only be increased, but this also causes the airflow generated by the fan to not be used effectively, thereby reducing the efficiency of the fan

Abstract

The invention discloses a fan assembly applied to an electronic device. The fan assembly comprises a housing, a fan, a throttle valve and a regulator. The housing is provided with an air outlet. The fan is arranged in the housing, and is applicable to providing air current, wherein, the air current produces air flow at the air outlet. The throttle valve is movably arranged in the housing, and located at the air outlet. The regulator is connected to the throttle valve for controlling the motion of the throttle valve to regulate opening size of the air outlet.

Description

technical field [0001] The present invention relates to a fan assembly, and in particular to a fan assembly applied to an electronic device. Background technique [0002] In recent years, portable electronic devices are developing towards miniaturization and multi-function. Portable electronic devices with more powerful functions usually have higher speed chips. However, the higher the speed of the chip, the more heat energy it will generate, coupled with the miniaturization of the portable electronic device, these factors make the heat dissipation capability of the portable electronic device very important. [0003] A fan is a fairly common component in electronic heat dissipation technology. It usually cooperates with heat dissipation fins to dissipate heat from high-power components to keep the temperature of the components within their operating temperature range. In addition, the active airflow generated by the fan can convect the interior of the electronic device with...
