Abstract
【解決手段】冷却装置5は、モータ用冷却水通路部8が、モータ用冷却水通路部8において冷却水を循環させるモータ用ウォータポンプ10と、機関用冷却水通路部7からモータ3に冷却水を導入するモータ用冷却水入口管8Aと、モータ3を冷却した冷却水を機関用冷却水通路部7に戻すモータ用冷却水出口管8Bとを含んで構成され、モータ用冷却水入口管8Aの上流端8aをロアタンク16に接続するとともに、モータ用冷却水出口管8Bの下流端8dを機関用冷却水入口管7Aに接続し、サーモスタット11の開弁時に、モータ用冷却水入口管8Aおよびモータ用冷却水出口管8Bを流れる冷却水を、ロアタンク16を通して循環させる。
【選択図】図4
Description
本発明の第3の態様としては、ラジエータのコア部が、電動ファンを有し、開口部を通して電動ファンに走行風を取り込むファンシュラウドを備え、回転電機用冷却水入口通路部の上流端が、開口部の下方において下流タンク部に接続されてもよい。
これにより、機関用ウォータポンプに比べて回転電機用ウォータポンプをより一層小型することができ、冷却装置をより一層小型化することができる。
具体的には、回転電機の冷却上限温度は、内燃機関の冷却上限温度よりも低く、回転電機は、内燃機関よりも低い温度の冷却水で冷却する必要がある。
図1〜図5は、本発明に係る一実施形態のハイブリッド車両の冷却装置を示す図である。
図1において、ハイブリッド車両1は、車体1Aのエンジンルーム1aの内部に内燃機関としてのエンジン2と回転電機としてモータ3とを収納している。
エンジンルーム1aの内部には冷却装置5が収容されており、冷却装置5は、冷却水によってエンジン2およびモータ3を冷却する。
ラジエータ6は、エンジン2に対して前方に設けられており、走行風と冷却水との間で熱交換を行うコア部14を備えている。コア部14はコア部14を通過する空気と熱交換を行い、高温の冷却水を冷却する。
まず、図4に基づいてエンジン2の冷機時の冷却装置5の動作を説明する。
図4において、エンジン2の冷機時には冷却水の温度が低いため、サーモスタット11が閉弁状態となる。このため、機関用ウォータポンプ9が駆動されると、冷却水は、機関用ウォータポンプ9、冷却水通路2a、閉弁されるサーモスタット11、バイパス管13および機関用ウォータポンプ9を循環する。これにより、エンジン2の暖機が行われる。
この結果、モータ用ウォータポンプ10の容量を小さくしてモータ用ウォータポンプ10を小型化できる。
エンジン2の暖機後には冷却水が高温となるため、サーモスタット11が開弁状態となる。このため、機関用ウォータポンプ9が駆動されると、冷却水は、機関用ウォータポンプ9、冷却水通路2a、開弁されるサーモスタット11、機関用冷却水出口管7B、アッパタンク15、コア部14、ロアタンク16、機関用冷却水入口管7Aおよび機関用ウォータポンプ9を循環する。これにより、エンジン2が冷却される。
以上の結果、モータ用ウォータポンプ10の容量を小さくしてモータ用ウォータポンプ10を小型化できる。
これにより、機関用ウォータポンプ9に比べてモータ用ウォータポンプ10をより一層小型することができ、冷却装置5をより一層小型化することができる。
