A bypass flow path-type active air flap (10) applied to a vehicle (1) of the present invention allows a bypass flow path to be formed in a surrounding space of the stagnant flow of driving wind, which is blocked by closing of an air flap (30) opened and closed by driving an actuator (20), by a bypass flow path device (40) with any one of or a combination of at least two of an air curtain (7), the hood (7), and an undercover (9), thus reducing pressure of the driving wind applied to the air flap (30). Accordingly, while the excellent sealing performance of the air flap (30) is maintained, the aerodynamic improvement effect is further doubled, and in particular, by forming the bypass flow path in various parts of the vehicle (1), side effects that may be caused by the improvement of the sealing performance of the air flap (30) may be resolved.

    본 발명의 차량(1)에 적용된 바이패스 유로 방식 액티브 에어 플랩(10)은 엑추에이터(20)의 구동으로 개폐되는 에어 플랩(30)의 폐쇄로 차단된 주행 풍의 정체 유동이 바이패스 유로 장치(40)에 의해 에어 커튼(7), 후드(7) 및 언더 커버(9) 중 어느 하나또는 2개 이상의 조합으로 정체 유동의 주변 공간에서 우회 유동 경로를 형성하여 에어 플랩(30)에 가하는 주행 풍 압력을 낮춰줌으로써 에어 플랩(30)의 우수한 실링성능이 유지된 상태에서 공력 개선 효과가 더욱 배가시켜 주고, 특히 바이패스 유로를 차량(1)의 다양한 부위로 형성함으로써 에어 플랩(30)의 실링성 개선에 의한 부작용(SIDE-EFFECT)을 해소하는 특징이 구현된다.
