Abstract

The invention discloses a fan module and electronic equipment. The fan module and the electronic equipment are used for solving the technical problem of the low utilization rate of wind generated by a fan due to the large system flow resistance of the fan. The fan module comprises a fan body and a fan shell. The fan body comprises a rotary shaft and multiple fan blades. The multiple fan blades are arranged on the rotary shaft and are driven to rotate through rotation of the rotary shaft. The fan shell comprises containing space and a wind guide opening. Multiple wind outlets are formed in the wind guide opening. The fan body is arranged in the containing space. Wind generated by the fan body is guided out to the outer portion of the containing space through the multiple wind outlets. The wind outlets distributed in a first area of the wind guide opening have the first aperture ratio, the wind outlets distributed in a second area of the wind guide opening have the second aperture ratio, and the first aperture ratio is different from the second aperture ratio.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a fan module and electronic equipment. Background technique [0002] With the rapid development of the electronics industry, the operating speed of electronic components in electronic equipment continues to increase, and a large amount of heat is generated during operation, which increases the temperature of itself and the system, which in turn affects the stability of the system. Therefore, the heat dissipation problem of electronic equipment is becoming more and more serious. are getting more and more attention. In order to efficiently remove the heat generated by the system in a limited space, heat sinks and centrifugal fans are generally used to dissipate heat. Specifically, an air guide is provided in the area close to the centrifugal fan, and a plurality of air outlets are arranged at the air guide, through which the wind generated by the centrifugal fan can be exporte...
