The present invention relates to a system for dynamometer testing of motor vehicles. The system includes a cooling device for cooling a braking device and/or a power-generating arrangement, such as the engine of a car. The system is arranged to, using the braking device, absorb power applied thereto by the power-generating arrangement. The cooling device includes a fan arrangement for producing an air stream, the air stream being intended to be directed towards the braking device and/or the power-generating arrangement and/or a heat exchanger for providing a cooling effect. The fan arrangement includes two substantially axially aligned fans, and the cooling device is arranged to rotate the fans in opposite directions relative to each other. The present invention also relates to a method. |
