Abstract

The invention discloses a fan device and an electronic device. The fan device comprises a volute and a vane wheel, wherein the vane wheel is arranged inside the volute, and comprises a hub and at least two fan blades; the hub has an axis; air inlets and air outlets are formed in the volute; airflow can enter the air inlets in the axial direction of the vane wheel, and can flow out of the air outlets in the radial direction of the vane wheel; the at least two fan blades are arranged on the hub; and the included angle formed by the axial path line of each fan blade in the at least two fan blades in the axial direction and a radial plane vertical to the axis is an acute angle.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a fan device and electronic equipment. Background technique [0002] With the continuous development of science and technology, electronic products have also been developed rapidly. In order to avoid damage to internal components caused by the heat generated by electronic products during work, fans are usually installed inside electronic products to promote the internal cooling of the casing. The heat is dissipated to the outside. [0003] In many electronic devices, a centrifugal fan is used, which includes: a volute; an impeller, the impeller is arranged in the volute; the impeller includes a hub, and at least two fan blades. The volute is provided with an air inlet and an air outlet, the air flow enters the air inlet along the axial direction of the impeller, and flows out of the outlet air along the radial direction of the impeller. [0004] However, in the process of r...
