Description

A high-efficiency atomizing cooling fan

technical field

The invention relates to a cooling fan, in particular to a high-efficiency atomization cooling fan.

Background technique

The cooling fan is an effective heat dissipation tool. The spray can suppress dust and adjust the atmosphere. When the water droplets evaporate, it can reduce the surrounding temperature by 4-8 degrees, and the surrounding area can reach 30-50 square meters. Make the environment clean, cool and comfortable. The airflow blown by the micro-mist through the powerful fan greatly increases the wind speed on the surface of the liquid, accelerates the diffusion of gas molecules, and plays a better heat dissipation effect. However, the existing cooling fan equipment has certain disadvantages in use, for example: due to the direction of the nozzle, the spray is relatively concentrated, not divergent, and it is easy to form water droplets in one place. In addition, due to the generation of water mist, electrical equipment such as fans It is not very safe to use.
