Abstract
The utility model relates to a plate-type sound elimination device for a large-scale air cooling fan. The plate-type sound elimination device is characterized by comprising a motor, a fan, an air duct and a sound eliminator, wherein the fan is arranged at the bottom of the motor, the air duct is sleeved at the outer part of the fan, the sound eliminator is arranged at the bottom of the air duct, a transition section is arranged between the air duct and the sound eliminator, a plurality of sound elimination sheets are arranged in the sound eliminator, perforated plates are arranged on the outer surfaces of the sound elimination sheets, and superfine sound elimination cottons are filled in the perforated plates. The plate-type sound elimination device for the large-scale air cooling fan has the advantages that the heights of the sound elimination sheets of the sound eliminator are 2000 mm, the thicknesses of the sound elimination sheets are 150 mm, the segment pitches are 400 mm, and the perforated plates having punching rates of 25% are arranged on the outer surfaces of the sound elimination sheets; and as the sound eliminator is arranged at the lower part of the sound elimination device for the large-scale air cooling fan, the air inflow fields of impellers of the fan on the upper part of the sound elimination device can be improved, the efficiency of the sound elimination device is improved by1.5%, the space of an air cooling island is adequately adopted, the mounting space of a device is unnecessary to be added, and an ultralow-noise level is achieved.
