摘要
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 fire smoke from the cooling fan.Remove the ordinary high temperature exhaust fan inner circle of impeller,two lead wind transverse distribution around outside cylinder catheter tube ends,will with the tube connected together;Set out front,the wind tube bend pipe,use air pipe inner cylinder induced gases from the wind from the bend,realized the purpose of cooling to motor,avoid the high temperature damage on motor.
