Abstract
A cooled electrical assembly is disclosed which includes a plurality of cooled components and a first cooling fan adapted to provide a cooling flow for cooling the cooled components, the first cooling fan including a blade holder and a fan blade, the fan blade having a fixed end stationary mounted to the blade holder and a free end adapted to swing for generating the cooling flow. The plurality of cooled components can include four substantially cylindrical components each having a centre axis, the four substantially cylindrical components being spaced apart and located such that the centre axis of each said substantially cylindrical component passes through a respective vertex of a quadrilateral, the free end of the fan blade being located between the four substantially cylindrical components and inside the quadrilateral.
