The invention relates to the technical field of vehicle ventilation, and discloses a compact ventilation device which comprises an air duct and a filter screen, the filter screen is fixed in the air duct, the air duct comprises two oppositely-arranged concave cambered surfaces, the two concave cambered surfaces protrude outwards in the direction away from each other, the starting ends of the concave cambered surfaces are connected with an inlet of the air duct, and the starting ends of the concave cambered surfaces are connected with an outlet of the air duct. The terminal end of the concave arc surface is connected with an outlet of the air duct; according to the compact ventilation device, ventilation and dust removal of the equipment compartment are achieved only through the air flue and the filter screen, impurities in air are taken away from the air flue through the viscous force of external airflow and the air pressure difference in the air flue, the dust removal efficiency is extremely high, few impurities adhere to the surface of the filter screen, blockage is not prone to occurring, and cleaning is convenient; meanwhile, a large number of parts such as middle flow guide plates, air inlet flow guide plates and air outlet flow guide plates are prevented from being used, the occupied space of the device is saved, and the device can be installed on a vehicle with the small available ventilation region.
本发明涉及交通工具通风技术领域,公开了一种紧凑型通风装置,包括风道和滤网,所述滤网固定于所述风道内,所述风道包括两个相对设置的凹弧面,且两个所述凹弧面沿相互远离的方向外凸,所述凹弧面的始端与所述风道的入口相连,所述凹弧面的终端与所述风道的出口相连;该紧凑型通风装置仅利用风道和滤网实现对设备舱的通风、除尘工作,利用外界气流的粘性力和风道内的气压差,将空气中的杂质带离风道,具有极高的除尘效率,使滤网表面附着杂质较少,不易堵塞,便于清洁,同时避免了使用大量的中间导流板、进风导流板和出风导流板等部件,节约装置占用的空间,可以安装在可利用的通风面积较小的交通工具上。
