Предлагается устройство направляющих лопаток для осевого вентилятора предназначено для преобразования вращательной составляющей скорости газового потока на выходе с крыльчатки преимущественно в осевую составляющую скорости. Устройство содержит обечайку направляющих лопаток, расположенных по потоку вентилятора и расставленных с промежутками между ними. Чередующиеся направляющие лопатки смещены в осевом направлении по отношению к остальным направляющим лопаткам таким образом, что чередующиеся направляющие лопатки находятся на первом осевом расстоянии от вентилятора, а остальные лопатки - на втором осевом расстоянии от вентилятора. В качестве переменных чередующиеся лопатки имеют часть на концевой части, обращенной к вентилятору, снятую таким образом, что передняя кромка чередующейся направляющей лопатки находится на первом расстоянии от вентилятора, а остальная часть направляющей лопатки находится на втором осевом расстоянии, и направляющие лопатки неравномерно распределены по периферии обечайки.An arrangement of guide vanes for an axial fan is proposed for converting the rotational component of the gas flow velocity at the exit from the impeller mainly into the axial velocity component. The device contains a shell of guide vanes located along the fan flow and spaced between them. The alternating guide vanes are axially displaced with respect to the remaining guide vanes in such a way that the alternating guide vanes are at the first axial distance from the fan, and the other vanes are at the second axial distance from the fan. As variables, the alternating blades have a portion on the end portion facing the fan, taken in such a way that the leading edge of the alternating guide vanes is at a first distance from the fan, and the rest of the vanes is at a second axial distance, and the vanes are unevenly distributed around the periphery shells.
