Abstract
Изобретение относитс к вентил торе- строению и может быть использовано в системах охлаждени электрических . Целью изобретени вл етс повышение эффективности охлаждени при снижении габаритов и материалоемкости и увеличение КПД. Вентил тор дл охлаждени электрической машины содержит установленные на валу 6 ротора 4 центробежное рабочее колесо 12 с лопатками 14 и 15, выполненными в виде тонких изогнутых дуговых профилей и размещенных на ступице 16с противоположно ориентированной выпуклостью через одну. Рабочее колесо 12 размещено в цилиндрическом кожухе 17, причем между валом 6 и ротором 4 и в статоре выполнены аксиальные каналы 5 дл прокачки охлаждающего воздуха. Кожух 17 снабжен двум цилиндрическими дефлекторами 18 и 19, диаметр которых равен диаметру рабочего колеса 12, причем дефлектор 18 расположен во входном отверстии кожуха 17, а дефлектор 19 - в кожухе 17 с противоположной стороны рабочего колеса 12 на входе в канал дл охлаждени , статора, 5 ил. (Л СThe invention relates to a fan and can be used in electric cooling systems. The aim of the invention is to increase the cooling efficiency while reducing the size and material consumption and increase the efficiency. The fan for cooling the electric machine comprises a centrifugal impeller 12 mounted on the shaft 6 of the rotor 4 with blades 14 and 15 made in the form of thin curved arc profiles and placed on the hub 16c with an oppositely oriented bulge through one. The impeller 12 is housed in a cylindrical housing 17, wherein axial channels 5 are provided between the shaft 6 and the rotor 4 and in the stator. The housing 17 is provided with two cylindrical deflectors 18 and 19, the diameter of which is equal to the diameter of the impeller 12, the deflector 18 being located in the inlet of the housing 17, and the deflector 19 in the housing 17 on the opposite side of the impeller 12 at the entrance to the cooling channel, stator, 5 il.
