摘要
Cooling device (15) for cooling semiconductor switching elements (10, 11), comprising - a first wall (17) having a first side (18) for carrying the semiconductor switching elements (10, 11) and having a second side (19) being opposite the first side (18), - a second wall (20) having a first side (21) that forms a main cooling channel (22) together with the second side (19) of the first wall (17) and having a second side (25) being opposite to the first side (21) of the second wall (20), and - a third wall (23) that forms an auxiliary cooling channel (24) together with the second side (25) of the second wall (20), wherein the second wall (20) comprises a connection means (26) that connects the auxiliary cooling channel (24) with the main cooling channel (22) in a fluid- conductive manner.
