Wind guiding structure and electronic device applying same

Abstract

The invention provides a wind guiding structure and an electronic device applying the same. The wind guiding structure comprises a fan and a guide impeller; the guide impeller is mounted on a wind outlet side of the fan, and comprises a base and a plurality of blades; the base comprises a wind inlet cylinder and an extension part; the wind inlet cylinder is close to the fan; the extension part extends to the periphery from the wind inlet cylinder; the connection part between the extension part and the wind inlet cylinder is in fillet transition; the blades are arranged on the base; each bladeis provided with a front-section linking part and a rear-section guiding part; the linking parts of the blades are close to the fan; the inclination angles of the blades at the linking parts are opposite to those of fan blades of the fan, so that a wind outlet field continues swirl characteristics; and the guiding parts extend from the linking parts to the outer part of the base, so that the windoutlet field is gradually converted from a high axial component state to a high radial component state, and is dispersed in a direction far from the axial center of the fan. The wind guiding structurecan continue and enhance the rotary swirl characteristics of the wind outlet field, reduces the axial wind resistance, and improves the wind exhausting efficiency of the fan.

Description

technical field [0001] The invention relates to the field of heat dissipation of electronic equipment, in particular to an air guiding structure and electronic equipment using the same. Background technique [0002] IP cameras can be widely used in video conferencing, network teaching, security monitoring and other fields. IP cameras are generally composed of lenses, image sensors, controllers, and control interfaces. In some application scenarios, a transparent dome cover is installed on the outside of the network camera. Because the camera module in the inner spherical shell needs to dissipate heat, a fan is installed on the surface of the inner spherical shell to draw hot air from the inner spherical shell to the inner layer. Between the spherical shell and the outer transparent cover, the temperature of the air in the entire body can be uniformed by means of air circulation. [0003] Because the gap between the inner spherical shell and the outer transparent cover is ve...

Problems solved by technology

However, it is not the best practice to directly stack two fans, the heat dissipation effect is not ideal, and some potential problems will still occur
