Method for producing a cooling element, and cooling element produced using such a method

A method of manufacturing a microcooling element (1), the method comprising:

• providing at least one first metal layer (11) and at least one second metal layer (12), oxidizing (101) the at least one first metal layer (11) and/or the at least one second metal layer (12), after oxidizing, structuring (102) the at least one first metal layer (11) and/or the at least one second metal layer (12) to form at least one recess (21, 22), and performing a direct metal bonding at a temperature between 850° C. and 1080° C. to join the at least one first metal layer (11) and the at least one second metal layer (12) to form the cooling element (1), wherein, in a bonded state, at least a partial section of a cooling channel is formed in the cooling element (1) by the recess (21, 22) in the at least one first metal layer (11) and/or the at least one second metal layer (12), and wherein, while performing the direct metal bonding, an inner side of the recess (21, 22) is provided completely free of an oxidized surface.
