The invention discloses a ventilation structure of a car roof. The ventilation structure comprises the car roof and car walls, wherein the car roof and car walls form a ventilation clearance; a left side plate and a right side plate that are parallel to each other are equipped on the car roof; a ladder folded plate located on the upper portion and a bottom mounting plate located on the lower portion are equipped between the left and right side plates; ventilation channels are formed among the ladder folded plate, the bottom mounting plate, the left side plate and the right side plate; and thebottom mounting plate is provided with a vertical plate that divides the ventilation channels into bent channels. In the invention, the ventilation channels are formed in terms of the enclosure of theladder folded plate, the bottom mounting plate, the left side plate and the right side plate; the inner cavity change is formed because of the ladder pattern of the ladder folded plate; the circumambulating of airflow is realized through the vertical plate to prevent too large and too concentrated airflow; a pull type filter screen can realize the filtration of dust; a cross-flow fan can realizeactive flow control; and an air guide elbow facilitates the entry of air. The ventilation structure is convenient in installation.
本发明公开了一种轿厢箱顶的通风结构,包括轿顶和轿壁,所述轿顶、轿壁形成通风间隙,所述轿顶上设置有两个平行的左侧板、右侧板,所述左侧板、右侧板之间设置有位于上部的阶梯折板和位于下部的底安装板,所述阶梯折板、底安装板、左侧板、右侧板之间形成通风通道,所述底安装板上设置有立板,所述立板将通风通道划分为弯折通道。本发明通过阶梯折板、底安装板、左侧板、右侧板围合形成通风通道,并且由于阶梯折板的阶梯状,从而形成内腔变化,而通过立板实现气流的绕行,避免气流过大和过于集中,通过抽拉式的过滤网实现对灰尘的过滤,通过贯流风扇能够实现主动的流向控制,通过导风弯头便于空气的进入,本发明安装方便。
