Abstract

The embodiment of the invention provides a combined fan, electronic equipment and an information processing method. The fan comprises a first fan assembly and a second fan assembly which are arranged coaxially, wherein the first direction of the first fan assembly conducting airflow is different from the second direction of the second fan assembly conducting airflow. High airflow and high wind pressure can be obtained without increasing the thickness of the combined fan. The heat dissipation capacity of the combined fan can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a composite fan, electronic equipment including the composite fan, and an information processing method. Background technique [0002] Considering that electronic devices such as desktop computers and notebook computers need to dissipate heat, fans are usually built into these electronic devices. Generally speaking, fans include centrifugal fans and axial fans. Among them, since the axial flow fan has a strong air flow, it is suitable for larger electronic equipment such as servers, desktop computers, and the like. For smaller electronic devices using centrifugal fans, such as notebook computers, when the power consumption is large, in order to improve heat dissipation efficiency, it is necessary to increase the air flow of the fan by increasing the thickness of the centrifugal fan. For notebook computers with limited volume , this approach is not advisable. Contents of the inve...
