    摘要： A mixed flow fan and a method of manufacturing a mixed flow fan. The method may include molding a fan wheel with a plurality of blades and a plurality of apertures. The plurality of blades extends radially outward from an axis of rotation and a plurality of apertures arranged with one aperture positioned between each pair of adjacent blades. The method also includes molding a plug having a conical shape. The plug includes a plurality of plugging members arranged circumferentially, where the number of the plurality of plugging members corresponds to the number of the plurality of apertures in the fan wheel. The method further includes welding together the fan wheel and the plug, where each of the plurality of apertures of the fan wheel is sealed by one of the plurality of plugging members of the plug to form a continuous surface.

    摘要： Fan assemblies, and in particular fan wheels and stator assemblies for fan assemblies, are disclosed. In one embodiment, the fan wheel includes a wheel back having an outer surface forming one of a curved dome-shape and a truncated cone-shape. The fan wheel may also include a plurality of fan blades radially spaced about and mounted to the outer surface of the wheel back. In one embodiment, each of the fan blades is formed from a segment of an airfoil-shaped aluminum extrusion defining at least one internal cavity. The fan blade first ends can be provided with a compound cut profile with at least one curved cut such that the first end of the blade is mounted flush to the wheel back outer surface. The stator assembly can also be provided with a plurality of stator blades formed from airfoil-shaped aluminum extrusion segments and provided with compound cut profiles.

    摘要： A vortex compressor comprises a housing (1) which is provided with an annular operating channel, an inlet port (2) and a discharge port (3) connected to the annular operating channel, and a cut-off (4) situated between the inlet port (2) and the discharge port (3). The disk (5) of the operating wheel mounted in the housing (1) is provided with a vane rim (6) accomodated in the annular operating channel. The housing (1) and cut-off (4) are provided with interconnnecting openings (7 and 8) which are arch-shaped and eequidistant from the vane rim (6). The inlet and outlet edges of the vane rim (6) are arranged coaxially at the edge of the lateral face of the disk (5). The inlet port (2) is in the form of an opening which is bow shaped and equidistant from the vane rim (6) and situated towards the inlet edges of the vanes, while the opening (7) in the housing (1) and the opening (8) in the cut-off (4) are situated towards the outlet edges of the vanes. The opening (7), the opening of the inlet port (2) and the cut-off are arranged in three segments on a plane perpendicular to the axis of rotation of the disk (5). The segment of the opening of the inlet port (2) is adjacent to the segment of the cut-off (4). Part of the segment of the cut-off (4) coincides with the segment of the opening in the housing, and the opening (8) in the cut-off (4) is situated in the part of the segment of the opening (7) of the housing (1) which coincides with segment of the cut-off (4).

    摘要： A compressor is disclosed wherein a diffuser flow path is curved in a radial direction in the vicinity of an outlet of a mixed-flow turbine (1), and guide vanes (7) each having a height larger than a maximum radius (r b ) at the outlet of the mixed-flow turbine (1) are arranged in the form of a circular wing row at the curved portion on a flow path surface of the diffuser plate (4) located toward a side plate. Thus, it is possible to keep uniform the flow within the diffuser (6) and to enhance the performance of the compressor. In addition, the axial length of the compressor may be shortened to thereby make the compressor compact in size.
