The invention relates to a cooling arrangement for an adjustable electric drive. The arrangement is arranged to conduct heat generated in electric devices by means of a liquid flowing through the cooling element to the surrounding space. The arrangement comprises a cooling element which is made of aluminum and to which components to be cooled can be fastened, and a base having means for fastening the cooling element. The arrangement is characterized in that the base is made of an aluminum profile that is stiffened and has mounting rails for receiving the cooling element and for preventing the movement of the cooling element transversely to the longitudinal direction of the mounting rails, and the cooling element can be fastened perpendicular to the profile base by using fastening means that support the cooling element so that components can be fastened to the cooling element, whereby the combined base and cooling element serve as a heat-conducting support base of the frequency converter.
