摘要： Injection molded ring fan embodiments and methods for making them. The methods influence material flow during the injection molding process such that a major portion of the materials flowing in opposite directions in the outer rings preferably flow past one another, intermix in a swirling relationship, and/or collide at an angle relative to one another. This results in better material mixing or integration of the flow fronts. In one embodiment, the thickness of the outer ring varies in different portions between adjacent fan blades.

摘要： A method to influence material flow during the injection molding of thermoplastic, polymeric ring type fans such that a major portion of the materials flowing in opposite directions preferably flow past one another, or collide at an angle relative to one another, rather than colliding at an 180 degree angle relative to each other to form weld lines. This flow bypassing results in better material mixing or integrating than merely allowing flow fronts to collide and cool. In one embodiment, a portion of the fan's ring is thickened in the weld line area to minimize the amount of material colliding at a 180-degree angle relative to each. Alternatively, at least one appendage could be added to the ring fan that will influence the material flow during molding conditions. Each appendage will be removed prior to introducing the ring fan to a cooling system.

摘要： A cooling fan assembly (10) includes a hubless polymer fan body molded around the perimetrical flange (20) of a metallic mounting hub (12). The fan body includes a circumferential ring (18) interlocked with the flange (20) and a plurality of fan blades (16) projecting outwardly from the ring (18). The fan body (14) is formed in an injection mold with molten polymer material being introduced into the mold at hot runner locations (25) disposed between the circumferential ring (18) and the root diameter (17) of the fan blades (16). At one face of the hubless fan (14), the circumferential ring (18) includes a plurality of uniformly spaced raised bosses (30). Each boss (30) defines a bore (31) configured to receive a balancing weight therein, preferably in the form of a balancing screw (35) threaded into the bore. The bosses (30) are interconnected by a stiffening ring (33) having a height substantially equal to the height (h) of the bosses (30). The stiffening ring (33) is modified between a plurality of pairs of bosses (30) to define a recessed flat (38). On the opposite face of the hubless fan (14), the circumferential ring (18) includes a plurality of raised tabs (40), arranged and configured to mate within a corresponding recessed flat (38). The corresponding recessed flats (38) and raised tabs (40) nest between stacked fan assemblies (10) to enhance the stability and increase the number and height of stacked sets of assemblies.

摘要： A ring fan and shroud assembly having a fan, a shroud member, a recirculating flow member, and a plurality of curved guide vanes. The fan has a hub with a plurality of projecting fan blades and an outer ring member. The shroud member is positioned around the outer ring member. The recirculating flow member is on the shroud member and is positioned forward adjacent the outer ring member. The guide vanes are positioned within the recirculating flow member and define an inlet angle, which is nearly tangential with an outer entry diameter radial surface of the recirculating flow member, and an outlet angle that is nearly radial along an inner exit diameter of the recirculating flow member.

摘要： A cooling fan (10) includes a plurality of blades (12) molded about a central hub plate (11) at an annular molded ring (13). A plurality of helical gussets (30) are formed on inlet side (25) of the molded ring (13) at the blade root (15) that are spaced apart to define flow gaps (32) therebetween, and are curved to substantially follow the airflow path through those gaps (32). A like plurality of radial ribs (40) may be formed at the outlet side (26) of the fan (10) that can include an indented stacking surface (41) that engages a contact surface (42) on the inlet side (25) to facilitate stacking of multiple fans. In another aspect, the fan blades (10) are configured to include elliptical or parabolic camber lines (C) that vary along the radial length of the blade so that the blade stacking, or the centers of gravity (CG) of radial blade segments, achieve a predetermined alignment under normal operating loads to minimize bending moments between blade sections.
