Abstract

FIELD: turbine fan engineering. SUBSTANCE: motor has shaft 16 which passes through motor 10 and carries impeller 20 of a turbine fan which is positioned outside of housing 11. The impeller of the turbine fan rotates with a speed that exceeds 50000 revolutions per minute thus forming the primary air flow which leaves the turbine fan through outlet port 35. Unit 20 of the turbine fan has a facility for generating the secondary air flow which at least partially cools the electric motor, is supplied from one or several outlet openings 28 and 30, and separated from the primary air flow. EFFECT: enhanced efficiency. 1 dwg

Изобретение относится к устройству для охлаждения электрического двигателя для турбовентилятора. Двигатель имеет вал 16, который простирается через двигатель 10 и поддерживает крыльчатку 20 турбовентилятора, которую размещают вне корпуса 11, принадлежащего к двигателю. Крыльчатка турбовентилятора вращается со скоростью, превышающей 50000 оборотов в минуту, создавая тем самым первичный поток воздуха, который через выпускное отверстие 35 выходит из турбовентилятора. Узел 20 турбовентилятора содержит средство, с помощью которого создают вторичный воздушный поток, который по меньшей мере частично охлаждает электрический двигатель и поступает из одного или нескольких впускных отверстий 28, 30 охлаждающего воздуха, отделенный от первичного потока воздуха.The invention relates to a device for cooling an electric motor for a turbofan. The engine has a shaft 16, which extends through the engine 10 and supports the turbofan impeller 20, which is placed outside the casing 11 belonging to the engine. The turbofan impeller rotates at a speed exceeding 50,000 revolutions per minute, thereby creating a primary stream of air that exits the turbofan through the outlet 35. The turbofan assembly 20 comprises a means by which a secondary air stream is generated that at least partially cools the electric motor and comes from one or more cooling air inlets 28, 30, separated from the primary air stream.
