Through -flow wind channel and have its thermantidote

The utility model provides a through -flow wind channel and have its thermantidote, including spiral case, snail tongue and tubular wine wheel, the spiral case with the snail ligulate becomes the through -flow space, the tubular wine wheel sets up in the through -flow space, the snail tongue is being on a parallel with extend in the axial direction of tubular wine wheel, be equipped with a plurality of discharge orifices that increase on the spiral case, the fluid can form certain negative pressure during surface flow in the spiral case, owing to be equipped with a plurality of discharge orifices that increase on the spiral case, gather the negative pressure of class formation aspirates the outside air through the spiral case internal surface, promote the fluidic flow by a wide margin, thereby can reduce the rotational speed of tubular wine wheel in the dependable flow, and then the noise of reduction fan, the discharge orifice that increases on the spiral case can be for the circular port, one or more combinations of slotted eye or long square hole, service environment according to the difference, choose corresponding spiral case for use, and great practicality.
