Abstract

본 발명은 차량용 교류발전기에 관한 것으로 교류발전기의 계자코일을 효과적으로 냉각시킬 수 있도록 하기 위하여 회전자(3) 양측의 냉각팬(10)중 일측 냉각팬(10)에 이면으로 형성된 내측날개(11a)를 형성함으로서 회전시 흡기홀(8)로 유기된 공기가 베어링(12)과 자극철심(7), 고정자코일(13)을 지나면서 냉각시키고 일부는 내측날개(11a)에 의해 회전자(3) 내부의 계자코일(6)은 냉각시키게 한 것이다.The present invention relates to a vehicle alternator, the inner blade (11a) formed on the rear surface of one of the cooling fan (10) of the cooling fan (10) on both sides of the rotor (3) in order to effectively cool the field coil of the alternator Air is cooled by passing through the bearing 12, the magnetic pole core 7, the stator coil 13, and part of the rotor 3 by the inner blade 11a. The internal field coil 6 is allowed to cool.

따라서 발전기의 온도상승을 효과적으로 저감시킬 수 있을 뿐만 아니라 내열성을 향상시킬 수 있게 된다.Therefore, not only the temperature rise of the generator can be effectively reduced, but also the heat resistance can be improved.
