Description

本開示に係る熱交換システムは、車両（ＶＣ）に搭載される熱交換システム（１０）であって、空気と熱媒体との間で熱交換を行う熱交換器（１００）と、熱交換器を通過するように空気を送り出すファン（３００）と、を備える。ファンは、車両の後方側に向けて空気を送り出す正回転動作と、車両の前方側に向けて空気を送り出す逆回転動作と、のいずれをも行うことが可能となっている。この熱交換システムは、ファンが逆回転動作を行う際において、熱交換器を通過する空気の流量が増加するように、熱交換器を通過した空気を吸引する吸引部（４１０，４５０，４６０，４７０）を更に備える。吸引部は、車両のエンジン（ＥＧ）に燃焼用の空気を供給するための吸気流路（４００）につながっており、熱交換器を通過した空気を吸引するように構成されている。 A heat exchange system according to the present disclosure is a heat exchange system (10) mounted on a vehicle (VC), the heat exchanger (100) performing heat exchange between air and a heat medium, and a heat exchanger. And a fan (300) for sending air to pass through. The fan can perform both a forward rotation operation for sending air toward the rear side of the vehicle and a reverse rotation operation for sending air toward the front side of the vehicle. This heat exchange system has a suction unit (410, 450, 460, 460) that sucks air that has passed through the heat exchanger so that the flow rate of air that passes through the heat exchanger increases when the fan performs reverse rotation operation. 470). The suction unit is connected to an intake passage (400) for supplying air for combustion to an engine (EG) of the vehicle, and is configured to suck air that has passed through the heat exchanger.
