Abstract
【解決手段】エンジンから排出された排気ガスの熱により純水を加熱する加熱部21側の7本の加熱部側ヒートパイプ部分23aと、この各加熱部側ヒートパイプ部分23aにより加熱された純水を排気ガスの熱により蒸発させる蒸発部22側の6本の蒸発部側ヒートパイプ部分23bとを有するヒートパイプ23を設ける。このヒートパイプ23にその蒸発部側ヒートパイプ部分の内部を流通する純水の流通速度を遅延させる流速遅延手段4を設けている。この流速遅延手段4に、各加熱部側ヒートパイプ部分で加熱された純水を蒸発部側において合流させる合流部を設ける。この蒸発部22側の合流部23cを、各加熱部側ヒートパイプ部分23aの流路断面積よりも大きな流路断面積に設定している。
