Abstract
【解決手段】熱交換器22が、第1の入口30と、複数の第1のチャネル34によって第1の入口30に接続された第1の出口44と、第2のチャネル38によって第1の入口30に接続された第2の出口40とを備える。バイパス弁24は、第1の出口44に接続された第1の入口50と、第2の出口40に接続された第2の入口52と出口54とを備える。また、出口54は、第1の入口30に接続されている。通常の動作モードでは、オイルが、チャネル34および出口マニホールド42を通して出口44へと通流する。熱交換器22内のオイルの温度が閾値よりも低いときには、バイパス弁24は、入口52から出口54へとオイルを通流させるように切り換わり、オイルは、入口チャネル32に沿って第2の部分38へと通流する。
