Air duct blade device used for vehicle

[0011] 1. Working principle

[0012] 1) Wind flow Q = area of ​​air inlet section A * wind speed V

[0013] 2) Wind pressure F = wind speed V square / 1600 (under one atmospheric pressure under standard conditions, the temperature is 15 degrees, and the air density = 0.01225Kg / m2)

[0014] 3) The effective power of the turbine W=Q*F

[0015] From the changes of the above three formulas, the following results can be obtained theoretically: changing the area A of a certain section in the air duct can change the wind speed. When the area A of the cross-section is reduced by half, the wind speed is doubled and the effective power is increased by four times.

[0016] 2. Design

[0017] 1. Analyze the driving data of the installed vehicle, the shape of the vehicle, and the parts subjected to wind resistance, and determine the size, shape and size, shape and quantity of the bell mouth.

[0018] 2. Determine the specifications and quantities of different wind rotors according to
