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.
A system for dynamometer testing of motor vehicles, including a cooling device for a braking device and/or a power-generating means, and having power-absorbing means for absorbing a power applied thereto by power-generating means, the cooling device including a fan arrangement for producing an air stream, said air stream being intended to provide a cooling effect, characterised in that said fan arrangement includes two fans, which are substantially axially aligned, and that the cooling device including means for rotating the fans in opposite directions relative to each other.
A method for cooling a braking device and/or a power-generating means in a system for dynamometer testing of motor vehicles, wherein power-absorbing means is used to absorb a power applied thereto by power-generating means, wherein a cooling device includes a fan arrangement for producing an air stream for providing a cooling effect, characterised in that the method includes the step of rotating two fans of said fan arrangement, which are substantially axially aligned, in such a way that the fans rotate in opposite directions relative to each other.
