Abstract
The invention discloses a double volute wind wheel fan and belongs to air exhaust devices. An existing single volute wind wheel fan has the defects of disaccording with an extractor hood in air suction, unstable in operation, and relatively low in operation efficiency. The double volute wind wheel fan comprises a first fan and a second fan. A first volute of the first fan is connected with a second volute of the second fan. A first air outlet of the first fan and a second air outlet of the second fan are converged together and are jointly connected with an air outlet port. When used for different rangers, the double volute wind wheel fan is even in air suction and enables a whole machine to be enlarged in air quantity, improves smoke suction effect, and remarkably reduces noise. Matching and electronic control of double motors are more suitable for independent or linkage operation of a single range or double ranges, improve efficiency of the whole machine and remarkably show the advantage of energy conservation. Different shapes of air outlets and corresponding ports are selected according to shell bodies of different extractor hoods so as to reduce air outlet resistance and vortex, and therefore air quantity is increased and noise is reduced.
