PROBLEM TO BE SOLVED: To provide a shutter structure of a vehicle heat exchanger which operates switching means by a simple constitution, and can reduce draft resistance.SOLUTION: In a shutter structure of a vehicle heat exchanger which is arranged at a vehicle front side or a vehicle rear side of the vehicle heat exchanger 200 having a plurality of laminated tubes 201a in which heat exchange mediums pass, and adjusts a draft amount of the vehicle heat exchanger 200, there are arranged switching means 402, 502a which can switch a first state that the switching means are located between the adjacent tubes 201a and a second state that the switching means are located so as to be overlapped with the tubes 201a. When an air velocity of an airflow progressing toward the vehicle heat exchanger 200 from the vehicle front side is lower than a prescribed value, the switching means 402, 502a are brought into the first state, and when the air velocity of the airflow exceeds the prescribed value, the switching means are transited to the second state from the first state by the airflow.SELECTED DRAWING: Figure 8
【課題】簡易な構成で開閉手段を作動させるとともに通風抵抗を低減させることが可能な車両用熱交換器のシャッター構造を提供する。【解決手段】内部を熱交換媒体が通過する複数の積層されたチューブ201aを有する車両用熱交換器200の車両前方側または車両後方側に配置され、車両用熱交換器200の通風量を調整する車両用熱交換器のシャッター構造において、車両前後方向から見て、隣り合うチューブ201aの間に位置する第1状態と、チューブ201aと重なり合うように位置する第2状態とを切り替え可能な開閉手段402、502aを設ける。開閉手段402、502aは、車両前方側から車両用熱交換器200に向かう空気流れの風速が所定値を下回っている場合には、第1状態となっており、空気流れの風速が所定値を上回った場合には、空気流れによって第1状態から第2状態に移行する。【選択図】図8
