Description

Dustproof and waterproof formula radiator fan

Technical Field

The utility model relates to a fan technical field specifically is a dustproof and waterproof formula radiator fan.

Background

The heat dissipation fan is generally classified into an axial flow fan and a centrifugal fan, and blades of the axial flow fan push air to flow in the same direction as the shaft. The impeller and propeller of an axial fan are somewhat similar in that, in operation, the majority of the airflow is directed parallel to the shaft, in other words, in the axial direction. The axial flow fan has the lowest power consumption when the inlet air flow is free air of 0 static pressure, and the power consumption is increased along with the rising of the counter pressure of the air flow when the axial flow fan is operated. The axial flow fan is usually installed on a cabinet of electrical equipment and sometimes integrated on a motor, and the axial flow fan has a compact structure, so that a lot of space can be saved, and meanwhile, the axial flow fan is convenient to install, and therefore, the axial flow fan is widely applied. When the centrifugal fan is operated, the blades push air to flow in a direction perpendicular to the axis (i.e., radial direction), the inlet air is in the axial direction, and the outlet air is perpendicular to the axial direction. In most cases, an axial fan is used to achieve the cooling effect, however, sometimes a centrifugal fan is needed if the air flow is discharged by rotating 90 degrees or a large wind pressure is needed. Fans also belong to centrifugal fans strictly.

At present, electrical equipment is at the in-process of using, can produce the heat and need carry out timely heat dissipation treatment, otherwise can lead to electrical equipment to damage, and current radiator fan is relatively poor to the protection of dust, and the fender aqueous vapor protection impeller that separates that moreover can not be fine to and the access security of power cord is lower, reduces the practicality.
