Patent ID: 8532154

Claim:
Power semiconductor arrangement comprising, in combination: (a) a plurality of power semiconductor devices arranged next to each other forming a linear array; (b) an elongate heat sink on which the semiconductor devices are mounted, said heat sink having a longitudinal axis; (c) a cooling element that is in close contact with the heat sink, wherein the cooling element has two linear coolant channels that extend parallel to the longitudinal axis of the heat sink and are designed as a feed channel and as a discharge channel, respectively, for a fluid coolant; and (d) a plurality of linear cooling channels that are located next to each other, and which branch off from the feed channel, run alongside the heat sink and thereafter empty into the discharge channel, wherein cooling channels that are located directly adjacent to one another branch off at different points around the circumference of the feed channel and terminate at different points around the circumference of the discharge channel.
