摘要： The present invention is to provide a modular fan assembly mounted in an electronic device comprising a frame having a defined opening for air circulation; at least two spaced apart fans disposed within the frame, each fan having a stator and a plurality of blades attached to the stator; and a divider disposed between the fans for partial separation wherein an outer end of the divider is smaller than a depth of the frame, thereby leaving a distance between the outer end of the divider and an outer surface of the frame so that an area of the opening for an escape of air from the fans is increased for effectively reducing a resistance of air flow and obtaining a maximum draft by means of the divider.

摘要： A centrifugal pump has an impeller rotatable by means of a drive shaft. The impeller has a plurality of radially extending vanes connected to a hub and a partial back shroud with sharpened leading edges. The pump has a pump casing with a back plate adjacent to the back side of the impeller. Spiral grooves on the back plate interact with the sharpened edges on the back shroud to aid in protecting the area between the back plate and the impeller by cutting of solids and expulsion of solids through an output port. Cutting bars on the front plate of the casing project into the pump intake and interact with front edges of the vanes to cut incoming solids in a liquid mixture. A preferred form of impeller has vanes with sharpened leading edges that extend in a generally radial plane. These vanes sweep backwardly from their leading edges and each vane is given a double twist between the leading edge and its trailing edge. This form of impeller has both an effective slicing action and an efficient transmission of kinetic energy to the fluid.

摘要： The disclosed system is directed towards a tray bracket. The tray bracket comprises a tray bracket inlet, the tray bracket inlet has tray bracket inlet coupling elements. A tray bracket outlet is coupled to the tray bracket inlet and the tray bracket outlet has a body. The tray bracket includes a plurality of tray bracket outlet passages contiguous with the body. The plurality of tray bracket outlet passages are aligned with fan passages of at least one fan unit. The tray bracket outlet passages and the fan passages provide low impedance to air flow and low noise. The tray bracket includes attaching mechanisms contiguous with the body. The attaching mechanisms are manually demountably coupled to the tray bracket inlet coupling elements.

摘要： A compressor casing structure in the region of a rotor blade ring through which there is an axial flow, having a multiplicity of axial grooves which extend from a first radial plane upstream of the blade-tip inlet edges into a second radial plane between the blade-tip inlet edges and the blade-tip outlet edges and have groove cross sections with parallel side walls. The center axes of the groove cross sections have, at the upstream groove ends, from the opening to the groove base, an angle of inclination with a circumferential component counter to the direction of movement of the blade. The center axes of the groove cross sections have, at the downstream groove ends, an angle of inclination with a circumferential component in the direction of movement of the blade.
