Patent number: 10107306Abstract: A housing for a fan or blower, in particular an axial fan, includes a wall ring (2) having an inlet nozzle section (3), an outer diffuser (6) having an inlet flow opening (7) and an outlet flow opening (8), and a holder for an electric motor (9) of the fan. The holder is arranged in an inner space of the housing. The outer diffuser (6) is formed by at least two partial ring sections that are connected to the outer circumferential surface via mechanical connection elements. The holder includes several struts (14) that are fastened to an inner circumferential surface of the outer diffuser (6) by one end, are circumferentially spaced apart, and are fastened in the edge region of the inlet flow opening (7). The struts can be installed by their other end to a motor flange (16) of the motor housing (17) of the electric motor (9).Type: GrantFiled: April 12, 2013Date of Patent: October 23, 2018Assignee: EBM-PAPST MULFINGEN GMBH & CO.

Patent number: 10072671Abstract: A diffuser (3) for a fan (2) of axial, radial or diagonal type of construction, has an inlet opening (10) and having an outlet opening (20) for a gaseous medium which flows through a diffuser interior (I), which is enclosed by an outer housing (30), in an axially oriented main flow direction (S) from the inlet opening (10) to the outlet opening (20). The cross section of the diffuser interior (I) increases from the cross section (11) of the inlet opening to the cross section (21) of the outlet opening (20), wherein the outer housing (30) forms an outer diffuser part (AD) which delimits the diffuser interior (I) to the outside. Along the main flow direction (S), the cross section of the outer diffuser part (AD) changes from a circular cross section (31) at the inlet opening (10) to a non-circular cross section (32) at the outlet opening (20).Type: GrantFiled: December 16, 2011Date of Patent: September 11, 2018Assignee: ebm-papst Mulfingen GmbH & Co.

Patent number: 8932019Abstract: A fan wheel (1) is designed as a radial or diagonal fan, comprising a top plate (2) with an inlet port (4), a base plate (6) and a plurality of fan blades (8) distributed around the inlet port (4) and around an axis of rotation (Z). Blade ducts extend (10) respectively between the adjacent fan blades (8). The blade ducts lead radially or diagonally outward from the area of the inlet port (4) and form blow-out ports in the outer region. The blade ducts (10) are designed, with respect to their effective flow cross-section, as large enough that during operation, a turbulent flow with a Reynolds number markedly greater than 2300 is achieved. The top plate (2) or the base plate (6) or both feature a rotationally asymmetrical geometry with a continuous profile, at least in angular sections encompassing the fan blades (8).Type: GrantFiled: February 24, 2011Date of Patent: January 13, 2015Assignee: EMB-PAPST Mulfingen GmbH & Co.

Patent number: 6462494Abstract: A tan having a fan wheel and an electric motor driving it, and a control unit for controlling the motor output as a function of fan-specific parameters. An actual-value signal corresponding to an actual rotational speed of the fan is measured and compared with a control signal corresponding to a required speed, and the actual speed is adjusted to the required speed by means of the control unit, wherefore the actual speed and the actual motor current or supply current are measured and conducted to a microcontroller as input signal variables, whereby the fan-specific data such as wheel diameter, density of the conveying medium, fan coefficients, motor coefficients, and a preset artificial characteristic curve ps=ƒ({dot over (V)}s ) are stored in the microcontroller as default values.Type: GrantFiled: March 23, 2000Date of Patent: October 8, 2002Assignee: ebm Werke GmbH & Co.Inventors: Jürgen Schöne, Hartmut Schneeweiss, Wilhelm Reinhardt
