Description
圧縮機を車両の内燃機関に取り付けるにあたり、吸入室を内燃機関とは反対側に位置するように形成したことを特徴としている。従って、吸入室やモータ駆動回路部の発熱部品への内燃機関からの非常に大きい輻射熱の影響が防止でき、結果としてモータ駆動回路部の冷却が促進される。
体ケーシング3との間に形成した連絡通路63を通じて本体ケーシング3の吐出口9を有するモータ5側の空間に通じている。
するように形成し、電動圧縮機1を内燃機関200に取り付けるにおいて、吸入室61を内燃機関200と反対側に位置するようにすることで、吸入室61やモータ駆動回路部101の発熱部品への内燃機関200からの非常に大きい輻射熱の影響が防止でき、結果としてモータ駆動回路部101の冷却がさらに効率的におこなわれる。
