摘要： A centrifugal fan includes a main plate that is fixed to the rotational shaft of a fan motor and driven by the fan motor, a shroud having an air inlet, and a plurality of blades disposed between the main plate and the shroud. Each blade includes a main blade set on its suction surface side and a blade cover set on its pressure surface side. The main blade is joined to the main plate and the shroud. The blade cover is joined to the main blade, and is biased toward the main blade under the air pressure during rotation. Thus, the joint force between the main blade and the blade cover is enhanced, thereby enhancing the strength of joint of engagement portions of the blade and reducing abnormal noise generated due to the presence of one or a plurality of gaps formed between the engagement portions.

摘要： The invention relates to the blades of a fan wheel. The invention particularly relates to a hollow profiled blade for a fan wheel. A hollow profiled blade according to the invention for a fan wheel is made from a planar semi-finished product and has a leading edge and a trailing edge as well as a compression side and a suction side. A hollow area is formed in the interior of the hollow profiled blade whereby the part of the planar semi-finished product forming the one side of the hollow profiled blade extends over the part of the planar semi-finished product forming the other side of the hollow profiled blade.

摘要： An airfoil array includes a laterally extending endwall 56 with a series of airfoils such as 28, or 38 projecting from the endwall. The airfoils cooperate with the endwall to define a series of fluid flow passages 74. The endwall has a hump 84 toward a pressure side of the passage and a less elevated profile toward a suction side of the passage for reducing secondary flow losses.
