Abstract：
 A dynamo driven ventilation and air blast exchanger features in the even flow and dynamo driven characteristics. Based on the traditional device, it adds an inside linear even flow barricade between which and the output grid forms into a secondary curve cavity. Due to the shape and structure of the linear even flow barricade, remaining constant differential static pressure at the end of the wind channel, sending the wind to wind blast device through the wind channel. After the treatment of the linear even flow barricade, the dynamic pressure decreases and the static pressure increases. Inside the secondary curve cavity between the linear even flow barricade and the output grid, an even flow field is formed with even distribution of wind height and width and meeting wind speed requirement for ventilation exchanging.
