Abstract

The invention discloses a cooling fan for an electrical device. The cooling fan comprises a shell, an impeller, an air outlet, an upper side plate (11), a lower side plate (12), an annular side plate(13), an arc-shaped guide plate (14), blades (21), a hub (22), a first base plate (23), a main air inlet and an auxiliary air inlet, and is characterized in that one end of the arc-shaped guide plateis connected with the upper side plate, the other end of the arc-shaped guide plate is not connected with the lower side plate, and a second base plate (24) is arranged at the radial outer peripheralend of the first base plate. According to the cooling fan, through the matched design of the arc-shaped guide plate and the second base plate, noise can be lowered under the condition that the air volume is guaranteed, and pressure fluctuation on the two sides of the arc-shaped guide plate is reduced.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of electrical / electrical equipment / systems, in particular to a cooling fan for electrical equipment. Background technique [0002] The heat dissipation device in the electrical / electrical device / system generally uses a heat dissipation fan for heat dissipation. The heat dissipation fan includes a housing 1, an impeller 2, an air outlet 3, an upper side plate 11, a lower side plate 12, a ring side plate 13, and an arc guide Plate 14, blade 21, hub 22, first base plate 23, main air inlet F1, auxiliary air inlet F2 (such as Figure 1-2 shown). However, the existing cooling fan has the problems of high noise and pressure fluctuations on both sides of the arc deflector. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a cooling fan for electrical devices. The cooling fan can reduce the air volume while ensur...
