Abstract
A transmission includes a housing made from a metallic material and is provided with a cooling structure in the form of a cooling element made from open-cell metal foam. The cooling element can be secured on the housing, in particular on an outer surface of the housing, by a screw connection and/or adhesive bonding and/or magnetically.

A transmission, comprising a housing made from a metallic material and including a cooling structure, said cooling structure including a plurality of cooling elements made from open-cell metal foam and individually and separately secured on an outer surface of the housing, and an intermediate layer containing silicone and thermally conductive particles provided between each of the plurality of cooling elements and the housing, wherein each of the plurality of cooling elements has an underside shape that matches a shape of a region of the outer surface of the housing to which each of the plurality of cooling elements is individually and separately secured, and a desired cooling capacity of the transmission is adjusted based on a choice of number, shapes, and location of the plurality of cooling elements.
A method for producing a transmission, said method comprising individually and separately securing on an outer surface of a housing made from a metallic material a plurality of cooling elements each having an underside shape that matches a shape of a region of the outer surface of the housing to which each of the plurality of cooling elements is individually and separately secured and made from open-cell metal foam to provide a cooling structure on the housing, providing an intermediate layer containing silicone and thermally conductive particles between each of the plurality of cooling elements and the housing, and adjusting a desired cooling capacity of the transmission based on a choice of number, shapes, and positions of the plurality of cooling elements.
