Abstract
This invention relates to a "fanner capable of enhancing operation features at different levels," including at least: a fan wheel and a driving unit. The driving unit drives the fan wheel to maintain at a constant rotational speed. The fan wheel includes at least a hub and plural blades extending radially outwards from the hub. The plural blades are arranged so that each blade overlap the next consecutive, neighboring blade. Or the mounting angles at the roots of the blades are less than 53 degrees, while the blade tips are configured to be less than 46 degrees. The solidity at the blade roots are greater than 1.5 and that at the blade tips are greater than 1, to ensure that the fan wheel is able to operate under a constant rotational speed thereby enhancing the heat dispersion effect of the fanner.
