摘要： A vortex wall (14) and impeller (30) assembly for a transverse or cross flow fan (10). The wall is intended to reduce blade rate tonal noise and is formed in a number of segments (15). The segments have noses with J shaped cross sections and are arranged so that the J tail (16) of one segment points in the opposite direction from the J tail of an adjacent segment. The spanwise widths (W), segment-to-impeller clearances (c) and setting angles (.theta.) vary randomly, within specified limits, among the segments.

摘要： A transverse fan impeller (10) having blades (31) that extend longitudinally parallel to the rotational axis of the impeller. Each blade has an airfoil cross section, defined by a chord line (Ch) and a camber line (Ca), and is positioned in the impeller at a setting angle (.GAMMA.). The outermost edge (Eo) of each blade is located at a distance (Rmax) from the rotational axis (Ar, Ar'). The angular spacing (.SIGMA.) between blades in the fan is uniform. Among the blades of the impeller, the values of at least one of the parameters distance from outermost edge to rotational axis (Rmax), length of chord line (Ch), maximum deviation of camber line from chord line (Dmax) and setting angle of blades vary randomly from reference values of these parameters. The random parametric variations reduce the blade rate tonal noise produced by a fan having such an impeller as compared to a fan having an impeller with uniform blade parameters.
摘要翻译： 一种横向风扇叶轮（10），其具有纵向平行于叶轮旋转轴线延伸的叶片（31）。 每个叶片具有由弦线（Ch）和弧线（Ca）限定的翼型横截面，并且以设定角度（GAMMA）定位在叶轮中。 每个叶片的最外边缘（Eo）位于距旋转轴线（Ar，Ar'）的距离（Rmax）处。 风扇叶片之间的角度间隔（SIGMA）是均匀的。 在叶轮的叶片中，从最外边缘到旋转轴（Rmax）的距离，弦线长度（Ch），曲线与弦线的最大偏差（Dmax）和设定角度 叶片与这些参数的参考值随机变化。 与具有均匀叶片参数的叶轮的风扇相比，随机参数变化减小了具有这种叶轮的风扇产生的叶片速率音调噪声。

摘要： An improved evaporator air management system for trailer refrigeration systems, including an electrically powered, vertical axis, axial flow fan, arranged so as to draw air through a horizontally mounted evaporator coil. The flow is then driven upward through a nozzle and discharged into the trailer. The nozzle shape graduates from a circular cross-section to a wide-aspect ratio rectangular cross-section, while turning through 90°. The preferred choice of axial flow fan for the invention is the vane-axial type incorporating outlet guide vanes. Provision is made for a single fan-nozzle configuration which may be either centered or transversely off-set with respect to the evaporator coil. An additional option provides for an arrangement with a pair of side-by-side fan-nozzles.

摘要： An axial fan assembly including a casing wall with a forward facing step formed therein and a fan rotor with blade tips, each having an aft facing step which radially overlaps the casing step so as to reduce the clearance backflow loss in the assembly. A vane is attached to the suction side of each of the blade tips with the vane having an aft facing step which radially overlaps the casing forward facing step to promote further reduction of clearance backflow. Variations on the invention include the option of an additional inlet bellmouth piece that further restricts the clearance flow and wedges integral to the casing step to improved flow stability.

A module can be ganged in various relationships to collectively provide the total capacity required by the bus. Each module includes an evaporator section, a condenser section and a power section including a compressor and an inverter. The evaporator sections have a return air compartment that extends a substantial distance across the roof of the bus such that a single design can meet the needs of various return air duct installations of various types of buses.

摘要： An inducer fan assembly includes a flow collector piece having a motor support surface, a toroidal collector, and a discharge region extending tangentially from the collector. A fan rotor is rotatably mounted relative to the motor support surface. The fan rotor includes a hub surface, and an outer circumferential edge. The fan rotor further includes a plurality of blades that extend from the hub surface. The plurality of blades extend from a leading edge to a trailing edge that extends beyond the outer circumferential edge. The plurality of blades include a first height and a second height that define a blade tip revolved contour. The collector is arranged radially outward from and axially off-set from the hub surface. An inlet casing piece is mounted to the flow collector piece. The inlet casing piece includes a contour that is substantially similar to the blade tip revolved contour of the fan rotor.
