    • PURPOSE: A ventilation system for controlling the location of a flange is provided to simplify a duct structure by controlling the location of a flange. CONSTITUTION: A ventilation system comprises a case(10), a vent unit, and a flange. The vent unit which is installed inside the case comprises an exhaust pipe connected to an outlet of the case. The vent unit comprises a body, a ventilation fan, and a scroll. The body is fixed to the case. An exhaust pipe is formed on one side of the body. The ventilation fan is installed inside the body. The scroll covers the ventilation fan and guides the airflow formed by the ventilation fan to the exhaust pipe. The flange which is mounted on the outer circumference of the case is connected to the duct member.
    • 目的:提供一种用于控制法兰位置的通风系统,以通过控制法兰的位置来简化管道结构。 构成:通风系统包括壳体(10),通风单元和凸缘。 安装在壳体内的排气单元包括连接到壳体的出口的排气管。 排气单元包括主体,通风扇和涡卷。 身体固定在箱子上。 排气管形成在主体的一侧。 通风扇安装在车身内。 涡卷覆盖通风扇,并将通风扇形成的气流引导到排气管。 安装在壳体的外周上的凸缘连接到管道构件。
