Abstract
Description
なお、インバータの冷却水の温度上限は、パワー素子を構成する半導体(シリコン:Si)の熱損失、耐熱性、及び冷却構造等で決定される。Siで構成される一般的なパワー素子の場合、例えば65℃程度までに温度上昇を抑える必要がある。
また、低外気温時は、エンジン内のオイル粘度の上昇によりクランキング動力抵抗が増大し、エンジン始動性が悪化する。特許文献1では、SiCインバータからの発熱を利用してエンジン始動性を向上させることが開示されている。
また、空調用のパワー素子と発熱体とが一体化されてヒータを構成する。このため、熱媒体を加熱するために要する発熱体の電力は、従来に比べて少なくて済み、かつ発熱体の負荷が低減するためヒータの信頼性も向上する。一方、空調用のパワー素子だけでは不十分な加熱量を発熱体が補うため、熱媒体の加熱が不十分となることはない。このように、本構成に係るヒータは、空調用のパワー素子と発熱体とが相互に補完し合うので、より効率良く熱媒体を加熱できる。
本実施形態に係る車両用空調装置10は、ハイブリッド電気自動車(Hybrid Electric Vehicle:HEV)やプラグインハイブリッド電気自動車(Plug-in Hybrid Electric Vehicle:PHEV)に搭載されている。
すなわち、ヒータコア30へ流れるクーラントは、温水ヒータ50によって加熱される。このように、車両側発熱機器14の冷却システム16と車両用空調装置10の暖房系統が統合されている。
高耐熱性の半導体素子は、一例としてSiCであるが、これに限らず、窒化ガリウム系やダイヤモンド系の半導体とされてもよい。
すなわち、PTC素子72からの熱は、電極板74及び熱伝導シート76を介して、クーラントに伝導される。また、パワー素子70からの熱は、ケース78を介して、クーラントに伝導される。
多層化させた温水ヒータ50は、PTC素子72を複数備え、分岐されたクーラント流路46各々に対して熱伝導シート76を介してPTC素子72を接触させ、クーラントを加熱する。なお、クーラント流路46に挟まれるPTC素子72は、その上下でクーラント流路46に接触する。
図4は、バルブ54が閉じられた状態である通常暖房運転におけるクーラントの流れを示す。
従って、本実施形態に係る車両用空調装置10は、空調用のパワー素子70の冷却を車両側発熱機器14の冷却システム16で冷却し、かつその熱を暖房空調に用いることとなる。
また、温水ヒータ50が用いられることで、低外気温時でも、エンジン18を停止した状態で暖房が可能となる。このため、車室内を暖房するためだけにエンジン18を作動させる必要がないため、燃費が向上する。
さらに、低外気温時のエンジン18の始動に温水ヒータ50で暖められたクーラントを用いることで、燃費が向上する。
図5は、バルブ54が開かれた状態であるバイパス暖房運転におけるクーラントの流れを示す。
一方、ラジエータ44をバイパスしないでクーラントを温水ヒータ50によって加熱すると、暖房のために必要なクーラントの加熱量が少なく、暖房の立ち上がりが早くなる。
従って、本実施形態に係る車両用空調装置10は、車両の冷却システム16と暖房空調に係る構成を統合し、より効率的な暖房空調を可能とする。
図6は、車両用空調装置10の第1変形例に係る構成を示す。なお、図6における図1と同一の構成部分については図1と同一の符号を付して、その説明を省略する。
図7は、車両用空調装置10の第2変形例に係る構成を示す。なお、図7における図1と同一の構成部分については図1と同一の符号を付して、その説明を省略する。
そして、車両と外部電源90とが接続状態の場合に、携帯型端末機器等を用いた無線による温水ヒータ50の制御が可能とされる。また、タイマーを設定することによる温水ヒータ50の作動が可能とされる。
