一种自散热型消防排烟风机。去掉了普通高温排烟风机的内循环叶轮,两引风导管横向左右分布在外筒两端,将内筒与外筒连接在一起;在内筒前端设置出风弯管,利用管道内气流诱导内筒气体从出风弯管排出,实现了给电机降温的目的,避免了高温损坏电机。
A self-cooling fire exhaust fan. The inner circulation impeller of the ordinary high-temperature exhaust fan is removed, the two draft tubes are horizontally arranged at both ends of the outer cylinder in horizontal direction, and the inner cylinder and the outer cylinder are connected together; the outlet bend is arranged at the front end of the inner cylinder, Cylinder gas discharge from the outlet pipe, to achieve the purpose of cooling the motor to avoid damage to the motor at high temperatures.
