PROBLEM TO BE SOLVED: To restrain reduction in the utilization efficiency of energy due to defrosting of an outdoor heat exchanger.SOLUTION: A thermal management device 10A for a vehicle includes a pipe 20 that passes through an engine 14 of the vehicle, a first solenoid valve 34 capable of switching the pipe 20 between a state in communication with pipes 22 and 24 and a cut-off state among a cooling water circulation passage 12 including pipes 22, 24, 26, 28 and 30 that pass through a radiator 32 without passing through the engine 14, a water pump (WP) 16 for circulating cooling water in the cooling water circulation passage 12, and an electric fan 64 for blowing air to an outdoor heat exchanger 52 of an air conditioner via the radiator 32. A cooling water control ECU circulates the cooling water via the WP 16 with the pipe 20 cut off from the pipes 22 and 24 by the first solenoid valve 34 when determining that frost is formed on the outdoor heat exchanger 52, and also blows air to the outdoor heat exchanger 52 via the radiator 32 by the electric fan 64.SELECTED DRAWING: Figure 1

    【課題】室外熱交換器の除霜のためにエネルギーの利用効率が低下することを抑制する。【解決手段】車両用熱管理装置10Aは、車両のエンジン14を経由する配管20、エンジン14を経由せずラジエタ32を経由する配管22,24,26,28,30を含む冷却水循環路12のうち、配管20を配管22,24と連通する状態及び遮断する状態に切り替え可能な第1電磁弁34と、冷却水循環路12に冷却水を循環させるウォーターポンプ(WP)16と、ラジエタ32を通じて空調装置の室外熱交換器52に送風する電動ファン64を含んでいる。冷却水制御ECUは、室外熱交換器52の着霜を判断した場合に、第1電磁弁34によって配管20を配管22,24と遮断させた状態でWP16によって冷却水を循環させ、かつ電動ファン64によってラジエタ32を通じて室外熱交換器52に送風させる。【選択図】図1
