[0002] The blades of the cooling fan push the air to flow in the same direction as the axis. The impeller of the cooling fan is somewhat similar to a propeller. When it is working, most of the airflow is parallel to the axis. When the inlet airflow of the cooling fan is free air with 0 static pressure, its power consumption is the lowest. When it is running, the power consumption will increase with the increase of the airflow back pressure. In mining, petroleum and chemical engineering, cooling fans are usually used to dissipate heat for large main motors.

The rotor blades are connected to the rotor center cage hub in the form of staggered long and short pieces, and the gap is increased, which is beneficial to increase the air volume and improve the quality and production efficiency. In the utility model device, the air outlet can gather the energy of wind, and the wind is blown out through the air guide plate to control the wind direction and the different positions of the wind outlet size, so that the air volume is large where the heat is large and the air volume is small where the heat is small, so as to achieve a targeted heat dissipation effect, reduce energy loss, improve the overall heat dissipation effect, and make the product have good performance and long life.

[0004] However, the above two methods still have the following defects in actual use: the heat dissipation fan does not have the function of cooling, so when cooling the large main motor, the wind blown out is the wind of natural temperature, and the heat dissipation efficiency is low.
