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 present application provides a fan assembly and a communication device. The fan assembly includes a casing for accommodating an axial flow fan, and the axial flow fan of the fan assembly is arranged in the casing during installation. In addition, the casing is also connected with an air guide cover, and 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. When in use, the non-uniformity of the airflow entering from the air inlet on the plane will generate a strong vortex, thereby increasing the broadband and narrow-band noise of the axial fan. The air supply volume can be increased by setting the axial flow fan, and the rectification grid realizes the function of air inlet guide and flow equalization, thereby reducing the turbulent flow noise of the fan assembly at the air inlet, thereby reducing the noise of the entire axial flow fan. And the rectifying grid is set in the air inlet, which reduces the occupied space.

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...
