Zusammenfassung:	An electrical system includes modules and a frame structure for mechanically supporting the modules successively in an arrival direction of cooling air. Each module includes a cooling element in heat conductive relation with one or more electrical components. The frame structure mechanically supports the modules so that the cooling elements are substantially in the same attitude and successively in the arrival direction of the cooling air. The cooling elements are shaped so that, when the modules are mechanically supported by the frame structure, the cooling elements conduct cooling air in a direction deviating from the arrival direction of the cooling air. Furthermore, at least a part of a flank of the heat transfer portion of each cooling element is oblique with respect to the arrival direction of the cooling air. Thus, each of the cooling elements receives a fresh portion of the cooling air.
