Abstract:
1. An extruded aluminum electrical circuit component carrier on which at least one electrical circuit component is to be mounted, said carrier comprising: a first side portion and a second side portion, wherein said first side portion comprises an area for mounting at least one first electrical circuit component part and said second side portion comprises an area for mounting at least one second electrical circuit component part, an inlet to which an inlet conduit for a cooling liquid can be connected, an outlet to which an outlet conduit for the cooling liquid can be connected, and at least one supply passage for the cooling liquid, wherein the at least one supply passage is formed through the first side portion of the carrier, and at least one return passage for the cooling liquid, wherein the at least one return passage is formed through the second side portion of the carrier, wherein the at least one supply passage is connected to the at least one return passage in series, wherein an area of a cross-section of the at least one return passage is smaller than an area of a cross-section of the at least one supply passage, whereby in use a flow velocity of the at least one return passage exceeds a flow velocity of the at least one supply passage so that an essentially uniform cooling capacity for the first and second electrical circuit component parts is achieved.
