<p>The invention relates to an arrangement for cooling braking resistors (9; 19) by ventilating air, wherein the braking resistors (9; 19) are adapted to dissipate electric energy caused by braking a track bound vehicle, in particular a rail vehicle, into heat, wherein the arrangement comprises:
- a radial fan (7; 17),
- a plurality of braking resistors (9; 19) to be cooled, characterised in that
- the fan (7; 17) is a radial fan (7; 17) adapted to deflect the air in different directions transverse to a rotating axis of the fan (7; 17),
- the plurality of braking resistors (9; 19) are arranged in at least some of the different directions,
- the rotating axis of the fan (7; 17) extends from top to bottom, or vice versa, so that, during operation of the arrangement, the cool air is guided from top to bottom to the fan (7: 17) and is deflected by the fan (7; 17) towards the plurality of the braking resistors (9; 19).</p> |
