摘要： An improvement to forwardly skewed axial fans whereby blade camber and rake are coordinated with skew. The blades are characterized in that a line defined by the points of maximum chordwise camber (f.sub.max) as a function of changing radial position (r) is on the leading edge side of the mid-chord line (M.sub.CL) at values of r toward the root of the blade, and is less forwardly skewed than the leading edge (LE), the mid-chord line (M.sub.CL), and the trailing edge (TE) of said blade; the blade is raked forwardly so that the trailing edge of the blade tip is axially forward of the trailing edge at the blade root; rake (k) increases monotonically as radial position r increases from 0.75R to 1.0R, R being the fan radius; the blade has a relatively large pitch ratio (P/D); and rake is corrected to reflect the chordwise position of maximum camber. As a result, the fan produces a flow that is generally in radial equilibrium having a reduced component of flow normal to the2 desired axial flow and normal to the tangential flow. The coordinated fan can be (but need not be) combined with a housing/band configuration for controlling airflow that recirculates (i.e., counter to the desired axial airflow) in a channel formed between the band and housing.
摘要翻译： 前进倾斜的轴流风扇的改进，其中叶片外倾和耙子与偏斜协调。 叶片的特征在于，作为随着径向位置（r）的变化而变化的最大和弦倾斜点（fmax）所限定的线在中弦线（MCL）的前缘侧上以r向r 并且不如前述边缘（LE），中弦线（MCL）和所述叶片的后缘（TE）向前倾斜; 叶片向前倾斜，使得叶片尖端的后缘在叶根处沿着后缘的轴向向前; 随着径向位置r从0.75R增加到1.0R，耙子（k）单调增加，R是风扇半径; 叶片具有相对较大的间距比（P / D）; 并且耙子被校正以反映最大弯度的弦向位置。 结果，风扇产生通常处于径向平衡状态的流动，其具有垂直于所需的轴向流并垂直于切向流的流动分量。 协调的风扇可以（但不必须）与壳体/带配置结合，用于控制在带和壳体之间形成的通道中再循环（即，与期望的轴向气流相反）的气流。

摘要： A plastic fan includes two injection molded parts, each of which includes its own hub and a set blades extending outwardly from the hub to a band. The two parts are co-operatively sized and shaped to be assembled into a single operable fan having: 1) a hub comprising the hubs of each of the component parts; 2) the blades of the component parts; and 3) a circumferential band comprising the bands of the component parts. The fan blade separation on each of the fan parts is relatively large, permitting separate injection molding of each part. The resulting fan may be designed to have far greater blade number and blade solidity that would be possible for a fan that is injection molded by standard techniques. The fan may be packaged in an airhandler assembly that includes a flexible cylindrical retraining member generally coaxial with, and external to, a rigid cylindrical member, the fan band and the stator assembly, so as to support the stator assembly and to maintain the parts in place. A conical airguide may be positioned axially between the fan assembly and the stators. Also disclosed are methods of assembling the airhandler described above; and a bell mouth airguide that guides airflow smoothly into the round fan.

摘要： A rearwardly curved centrifugal blower having an annular envelope around the impeller, so that the rotating impeller draws air in through a central inlet and forces it radially outward into the envelope and out of an annular discharge. Multiple airfoil vanes are positioned in the annular envelope, in two axially displaced stages. The vanes are angled to turn and diffuse airflow entering the envelope.

摘要： Stationary flow control vanes positioned to encounter and redirect recirculating airflow provide a surprising combination of efficiency, low noise, and manufacturability for shrouded, banded, axial fans that are positioned in a housing. Such fan and housing combinations reduce swirl in recirculating airflow, so that the airflow entering the fan (which includes the recirculating airflow) is more ordered and fan performance is improved. The invention is particularly suited for fans that draw airflow through an upstream heat exchanger. It can also be applied to fans that blow air through a downstream heat exchanger. The invention is also suited for ducted fans.

摘要： Boundary layer separation in a rearwardly skewed centrifugal impeller can be better controlled by designing the impeller blades with an "S" camber, i.e., with rearward curved radially extending blades in a centrifugal blower. The blades have a positive camber at a radially inward region and a negative camber at a radially outward region of the blade.
