Definitions

  • the invention relates to a ventilator according to claim 1 or claim 2.
  • the WO 2004/094835 A1 describes a fan with a fan conveyor channel and fan disposed therein, which is rotatable about a central axis and has a central hub with an outer periphery on which fan blades are fixed, which extend with their radial outer edges to an outwardly limiting surface and which crescent-shaped Have leading edges and which are provided in the region of the radially outer edge with flow elements, which are designed for flow around this radially outer edge from the pressure side to the suction side compensating flow as Umströmungshindernisse.
  • the object of the invention is to disclose a fan, which has in a compact design, a further noise reduction and higher efficiency, with a protective grid is integrated with the same fan in the invention.
  • the housing (1) of the fan which is made of plastic, comprises the elements (1.1), cylindrical flow guide (1.2), guide vanes (1.3) and diffuser (1.5) which are decisive for the increase in efficiency in a compact component integrated, wherein the guide vanes simultaneously take over the connection of the motor carrier (1.4), the use of external rotor motors allows a particularly compact design.
  • the object is achieved in that profiled wing (2.2) and Nachleiteriel (1.3) are used, the radially outer ends (2.3) of the impeller blades (2.2) are provided with flow elements (winglets) and wherein the head gap between impeller blades (2.2) and cylindrical flow guide (1.2) is designed to be particularly small, which is made possible only by using special plastics and injection molding techniques.
  • the housing (1) takes over several functions at the same time and requires relatively little space.
  • the housing (1) takes over the suspension of the complete impeller (2) with its electric drive motor (5), which is designed as an external rotor motor.
  • the transmission of all forces and torques acting on the fan to the outside takes place via the guide vanes (1.3) connected to the engine mount and housing.
  • This Nachleiteriel (1.3) which reduce the peripheral component of the outflow velocity, contribute with their special profiling significantly to increase the static efficiency of the fan.
  • the inlet nozzle (1.1) of the housing in this case has the task to accelerate the fluid from the suction-side space largely loss and has this purpose in the flow direction on a special, narrowing contour.
  • this gap is made very small. Furthermore, flow elements (winglets) (2.3) ensure a significantly reduced generation of noise.
  • the flow passes downstream of the impeller (2), deflected by the Nachleiterieln (1.3), in the diffuser (1.5), ie in an expanding flow channel.
  • the diffuser (1.5) in particular the axial component of the outflow velocity is reduced, which contributes to a further increase in the efficiency and thus the performance of the fan.
  • a protective grid (3) which is designed in particular as a mesh grid, fastened.
  • Another aspect of the invention is that external rotor motors, either in AC or in EC technology, are used. This allows a particularly compact design, with EC motors still bring an additional efficiency advantage.
  • FIG. 1 shows a fan, here an axial fan in longitudinal section with its housing (1), in the flow direction a specially trained, narrowing contour of the inlet nozzle (1.1) to which a cylindrical flow guide (1.2) and thereto an expanding flow channel, a diffuser (1.5) connects.
  • the cylindrical flow guide (1.2) is the impeller (2) arranged, whose vane tips, which are designed as special flow elements (winglets), to minimize the noise generation and losses of efficiency only a very small distance from the cylindrical flow guide (1.2).
  • the impeller (2) with the housing (1) fixedly connected Nachleitulatel (1.3) are arranged, the hub side fixed to the motor carrier (1.4) are fixed to which the drive motor (5) together with impeller (2).
  • a protective grid (3) is arranged, which can be fastened both inside and outside of the diffuser (1.5).
  • FIG. 2 shows the axial fan in an oblique front view in which in the housing (1) the spatial arrangement of the impeller (2) with impeller hub (2.1) and motor (5) is shown. Also shown are fastening devices (1.6) in the inlet nozzle (1.1), which are designed here as holes.
  • FIG. 3 shows the axial fan in plan view with the inlet nozzle (1.1), impeller (2) and protective grid (3).
  • the outer shape (1.11) of the inlet nozzle (1.1) not only round, as shown here, but also have a square, rectangular or other shape.
  • FIG. 4 the axial fan is shown in an oblique rear view with protective grid (3) and centrally arranged terminal box (4).
  • Terminal box (4) can be releasably attached both to the protective grid (3) and to the motor carrier (1.4).
  • FIG. 5 shows a section of the axial fan with impeller and Nachleitulatel, in which the leading edges (2.21) of the winding wing (2.2) on the impeller hub (2.1) are preferably concave and arranged crescent-shaped leading in the direction of rotation. Furthermore, it is shown that the Nachleiteriel (1.3) are curved multi-dimensional, wherein the leading edges (1.31) are preferably sickle-shaped and their trailing edges (1.32) are preferably serrated or wavy.
  • FIG. 6 further shows a section of the axial fan, in which the trailing edges (2.22) of the wings (2.2) may be convex and serrated or wavy and whose radially outer ends are formed as a winglet (2.3).
  • the wings (2.2) designed as winglets (2.3) at the radial end contribute to a substantial reduction in the flow vortices and thus to a significant reduction in noise.
