The wind circle has nothing to do with several layers of film blowers.Whether it is a single layer,two layers,three layers,five layers,seven layers and nine layers,its principle is the same.There is not much in the wind circle.You can take it apart to have a look
The most important thing in the wind circle is the wind deflector.Its function is to let the air inlet under the wind circle.The incoming wind blows the membrane column (bubble) evenly through the sealing plate.Let me give you an example.If your palm is closed,it is a wind deflector.The handle is square.When you blow from under the palm,the air you blow out is blocked by the palm.It will flow evenly from the circumference of the palm to the upper part of the palm (because the wind ring is sealed,there is no scattering from the circumference).The wind circle is the same as this principle,with bubbles above the palm (wind circle).When the incoming air is blocked by the wind deflector (palm),the air flow will flow evenly from the circumference of the palm to the top of the palm,and the bubble is just above the palm (wind deflector).Its purpose is to use the wind diverted from the wind deflector to evenly from the wind deflector to evenly blow the membrane wall (column),so that its thickness is the same without deviation.
