Patent ID: 7800220

Claim:
A power electronic arrangement comprising: an insulating substrate which is provided with one or more metallization surfaces, a cooling element arranged beneath the insulating substrate and one or more power electronic components which are disposed on one side of the insulating substrate in opposite relationship to the cooling element on respective metallisation surfaces, wherein disposed on the surface of the insulating substrate that is in opposite relationship to the cooling element or that is towards the cooling element is a metal layer portion of a thickness of between 0.1 mm and 2 mm, which projects beyond the insulating substrate at all sides, wherein the insulating substrate is a ceramic substrate and the metal layer portion is bonded or actively soldered on to the insulating substrate, and wherein the region of the metal layer portion that projects beyond the insulating substrate forms a metal flange which borders the insulating substrate, the cooling element has one or more openings on its side that is towards the insulating substrate beneath the insulating substrate and provided beneath the insulating substrate is a cavity delimited by the insulating substrate and by wall surfaces of the one or more openings for receiving a liquid cooling agent and the metal flange is connected to the cooling element wherein the power electronic arrangement has a peripherally extending clamping frame overlapping the metal flange and the metal flange is clamped between the clamping frame and the cooling element and is thereby connected to the cooling element, wherein the clamping frame is connected to the cooling element by means of two or more clamping screws.
