Abstract:
1. A cooled base plate for electric components, the base plate comprising: a first side configured for attaching exothermal electric components thereto; and a second side, opposite to the first side, into which a cooling channel system is embedded, the cooling system having a cooling fluid inlet at a first end of the base plate and a cooling fluid outlet at a second end of the base plate, wherein a thickness of the base plate increases in a direction from the inlet of the cooling channel system towards the outlet of the cooling channel system corresponding to a flow direction of a cooling fluid for at least a portion of the length of the base plate, and wherein the cooling channel system is embedded at a substantially even distance from the first side onto which the electric components are attachable, wherein the cooling channel system comprises separate, finned pipes that are embedded in grooves provided in the base plate at a substantially even distance from the first side onto which the electric components are attachable, the grooves being substantially parallel to each other such that the separate, finned pipes respectively embedded therein are independent from each other entirely between the first and second ends of the base plate, wherein a heat transfer surface of the base plate including the grooves in the base plate and associated with the finned pipes increases in the flow direction of the cooling fluid, and wherein a protrusion of the finned pipes from the base plate reduces respectively in the flow direction of the cooling fluid.
