"24V DC Cooling Fan" impeller
Centrifugal fan impeller is the main component of energy transfer, which consists of the front plate, rear plate, the blade and hub components. There backward curved blades, Radial and forward curved (see centrifugal blade shape, Figure 2-16), backward curved airfoil blade shape is divided, straight and curved plate type. Form premarket impellers have straight front plate, tapered front plate and curved front plate three.
"24V DC Cooling Fan" collector
The gas is introduced into the impeller in two ways, one is a direct inspiration from the atmosphere, known as free intake; the other is to use the suction tube or airbox intake. No matter what kind of intake way, you need to import the device before the impeller current collector. Role of current collectors is to ensure the air flow can be uniformly distributed in the impeller inlet section, the value of imports to achieve the required speed, and air flow into the impeller at minimal loss situations. Collector in the form of a cylindrical, conical, curved, cylindrical and cone curved cone, etc., arc, arc cone good performance, is a large "24V DC Cooling Fan" fans used to improve the efficiency of the fan, efficient fan basically using cone curved collector.
