Axial ventilator for refrigeration system of rail vehicle, has impeller with hub and blades i.e. sickle blades, where sweeping angles between beaded line and tangents are plotted over radius of impeller and comply nonlinear function
The ventilator has an impeller (1) provided with a hub and multiple blades (3) i.e. sickle blades. Center of gravities of profile sections (3.1 to 3.8) form a spatially curved beaded line (5). Sweeping angles between the beaded line and tangents formed on the lines, are plotted over a radius of the...

| description | The ventilator has an impeller (1) provided with a hub and multiple blades (3) i.e. sickle blades. Center of gravities of profile sections (3.1 to 3.8) form a spatially curved beaded line (5). Sweeping angles between the beaded line and tangents formed on the lines, are plotted over a radius of the impeller and comply a nonlinear function e.g. square function. A motor carrier is provided on a suction side or on a pressing side of the impeller, and is coaxial to the impeller.
Die Erfindung betrifft einen Axialventilator, insbesondere für die Kühlanlage eines Schienenfahrzeuges - mit einem Laufrad, das eine Nabe sowie eine Mehrzahl von Schaufeln aufweist; - die Schaufeln sind Sichelschaufeln; - die Schwerpunkte der Profilschnitte bilden eine räumlich gekrümmte Aufflädellinie; - die Pfeilungswinkel zwischen der Auffädellinie und hieran gelegten Tangenten, aufgetragen über dem Radius des Laufrades, folgt einer nichtlinearen Funktion. |
