Description

자동차용 교류발전기의 냉각장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본원 발명의 일실시예를 나타내는 자동차용 교류발전기의 종단면도.
제2도는 제1도의 실시예에 사용하는 냉각팬을 나타내는 정면도.

Claims (2)

  1. 회전자의 양쪽면에 이 회전자와 동기해서 횐전하는 냉각팬을 배치하고, 이 냉각팬의 각각을 1쌍의 브래킷내에 수용하고, 상기 각 브래킷에는 상기 냉각팬의 회전에 의해서 외부로부터 도입되는 냉각풍을 교류발전기내에 통풍시키는 흡입공 및 토출공을 형성하고, 이 냉각풍에 의해서 교류발전기의 고전다권선 및 한쪽의 브래킷내에 장착된 교류출력 정류용 다이오드 등을 냉각하도록 이루어진 자옹차용 교류발전기의 냉각장치에 있어서, 상기 냉각팬은 상기 다이오드를 가진 한쪽의 브래킷쪽의 팬보다 다른 편의 브래킷쪽의 팬의 흡입용량을 크게 해서, 상기 다른 편의 브래킷쪽의 팬의 흡입용량을 크게 해서, 상기 다른 편의 브래킷팬에 있어서의 흡입부의 부압을 상기 다이오드를 가진 브래킷쪽의 팬의 흡입부보다 크게 설정해서 이루어진 것을 특징으로 하는 자동차용 교류발전기의 냉각장치.
  2. 제1항에 있어서, 상기 2개의 냉각팬중 흡입용량을 크게해서 이루어진 팬은 합성수지에 의해서 몰드성형된 터보팬으로 이루어진 자동차용 교류발전기의 냉각장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
