УСТРОЙСТВО ДЛЯ ОХЛАЖДЕНИЯ ЭЛЕКТРИЧЕСКОЙ ГЕНЕРАТОРНОЙ УСТАНОВКИ

摘要

The invention relates to a current generator unit consisting of a generator and reciprocating engine as the drive system, in particular consisting of a synchronous generator and a diesel engine and comprising a cooling device for the common cooling of the generator and reciprocating engine. Said unit comprises a fan wheel ( 2 ) that axially aspirates the cooling air (L) on the motor side and evacuates the latter radially and that has a first passage ( 49 ) located in the radial exterior zone of the blades ( 4 ) and a second passage ( 50 ) located radially inside the blades ( 4 ). A small portion (S 2 ) of the cooling air (L) ("generator cooling air") is fed exclusively to the generator on the motor side via the first passage ( 49 ) and is evacuated via the second passage ( 50 ) and a predominant portion (S 1 ) of the cooling air (L) ("motor cooling air") is fed to the reciprocating engine.
