To warm-up a vicinity of an air-intake port of an internal combustion engine before starting the engine while effectively utilizing waste heat from an inverter 21, a motor generator 22 for running or the like.SOLUTION: A cooling device of a series hybrid vehicle comprises: a first cooling water circuit 1 for mainly cooling a water jacket 11 of an internal combustion engine; a second cooling water circuit 2 that cools an inverter 21, a motor generator 22 for running or the like; and a refrigeration cycle 3 constituting a vehicle interior air-conditioner. The refrigeration cycle 3, through which first cooling water circuit 1 is thermally connected to the second cooling water circuit 2, absorbs heat of cooling water in the second cooling water circuit 2, as vaporization heat in a chiller 37, and heats cooling water in the first cooling water circuit 1 as condensation heat in a capacitor 36 for warming-up an engine, where the heated cooling water is circulated in the air-intake port water jacket 16.SELECTED DRAWING: Figure 1

    【課題】インバータ21や走行用モータジェネレータ22等の廃熱を有効利用して内燃機関の吸気ポート周辺を始動前に暖機する。【解決手段】シリーズハイブリッド車両の冷却装置は、内燃機関のウォータジャケット11を主に冷却する第1の冷却水回路1と、インバータ21や走行用モータジェネレータ22等を冷却対象とする第2の冷却水回路2と、車室空調装置を構成する冷凍サイクル3と、を備える。冷凍サイクル3が第1の冷却水回路1と第2の冷却水回路2とを熱的に接続しており、チラー37において気化熱として第2の冷却水回路2の冷却水の熱を吸収し、エンジン暖機用コンデンサ36において凝縮熱として第1の冷却水回路1の冷却水を加熱する。加熱された冷却水は、吸気ポートウォータジャケット16を循環する。【選択図】図1
