Problems solved by technology

On the one hand, since the power consumption is proportional to the cube of the speed, the multi-stage motor is limited by the space size, and its performance improvement is limited so that the speed cannot continue to increase
On the other hand, the rapid increase of multi-level noise makes it difficult to meet the strict equipment noise admission standards, thus becoming an important bottleneck restricting its continuous evolution

Abstract

The invention provides a fan assembly and a communication device. The fan assembly comprises a housing for containing an axial fan, wherein the axial fan of a fan assembly is arranged within the housing when arranged. In addition, the housing is further connected with an air guide cover, the air guide cover is provided with an air inlet, and a rectifying grid is arranged in the air inlet of the air guide cover. In use, non-uniformity on a plane of airflow entering from the air inlet creates a strong vortex, thereby increasing axial flow fan broadband and narrow-band noise. Through the arrangedaxial fan, the air supply amount can be increased, air inlet air guide and flow equalizing functions can be realized by the rectifying grid, so that turbulence noise of the fan assembly in the air inlet can be reduced, and the noise of the whole axial fan can be reduced. Moreover, the rectifying grid is arranged in the air inlet, so that occupied space is reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a fan assembly and communication equipment. Background technique [0002] With the advent of the 5G era, the requirements for the integration and power consumption of ICT (Information Communications Tecknology, Information and Communication Technology) equipment continue to increase. At present, the power consumption of a single slot of core router equipment has reached 2000W and is still increasing. At the same time, the high heat dissipation generated by high power consumption chips poses a serious challenge to the long-term stable operation of the device. As the core component of system heat dissipation, the performance improvement of the fan box has become a key technology to solve the heat dissipation bottleneck and support the evolution of high-power consumption devices. [0003] In the existing fan box space, since the air volume is directly proportio...
