In order to solve problems accompanying the super slimming of an air ventilation outlet, provided are an air ventilation apparatus and a method thereof, which can naturally adjust an air ventilation discharge wind direction by applying a method different from a conventional wind direction adjusting wing. A basic principle of the present invention of adjusting the wind direction by applying a Coanda effect is to design air ventilation apparatus such that the wind direction is adjusted upward or downward by causing the Coanda effect on one curved surface of the air ventilation apparatus connected to the skin surface of a dashboard garnish and preventing the Coanda effect from being caused on an opposite surface. In addition to the Coanda effect, a structure for artificially forming a vortex is added to the air ventilation apparatus to maximize the Coanda effect. In a wind direction adjusting manner of the present invention, the wind direction is not directly changed using a wind direction adjusting wing and a guide related thereto, but the wind direction is changed due to the Coanda effect and the vortex formation.

    에어벤트 토출구의 초슬림화에 수반되는 문제점을 해결하기 위하여 종래의 풍향조절윙과 다른 방식을 적용하여 에어벤트의 토출 풍향을 자연스럽게 조절할 수 있는 에어벤트 장치 및 방법을 제안한다. 본 발명에서 코안다효과를 응용하여 풍향을 조절하는 방식의 기본 원리는, 대쉬보드 가니쉬의 스킨면과 연결된 에어벤트의 한쪽 곡면에서 코안다효과를 만들어내고 반대쪽 면에서는 코안다효과의 생성을 막아 풍향이 상향 또는 하향되도록 에어벤트를 설계한다. 또한 이러한 코안다효과와 더불어, 인위적으로 와류를 형성하는 구조를 에어벤트에 추가하여서 코안다효과를 극대화한다. 즉, 본 발명의 풍향 조절 방식은 풍향조절윙 및 이에 관련된 가이드를 이용한 직접적인 풍향의 변경이 아니라, 코안다효과 및 와류 형성에 의한 풍향 변경이다.
