Abstract
A cooling device for a high-power semiconductor module has a cooler lower part (1) and a cooler upper part (2), with the cooler upper part (2) being connected to the cooler lower part (1) by an integral material connection. The cooler upper part (2) has a cooling plate (20) composed of metal matrix composite, for at least one semiconductor component (4) to be fitted to. A metal border (21) is integrally formed on the cooling plate (20) in order to allow an integral material connection between the cooler upper part (2) and the cooler lower part (1). This results in a cooling device which can be produced easily and whose cost is low.
Claims18
A cooling device for a high-power semiconductor module, said cooling device comprising:
- a lower part, said lower part being made of solid metal;
- and
- an upper part, said upper part comprising a metal matrix composite inner plate for at least one semiconductor component to be placed on it, and said upper part comprising a metal peripheral edge surrounding said plate on its periphery, said inner plate being infiltrated with metal of said peripheral edge, forming a single piece upper part;
- wherein said upper part is connected to the lower part by an integral material connection between the metal peripheral edge and the lower part.
A cooling device for a semiconductor module, said cooling device comprising:
- a lower part entirely made of a first material;
- and
- an upper part for receiving at least one semiconductor component, the upper part comprising an inner plate formed of a second material, and comprising a peripheral edge formed of the first material about the inner plate, said inner plate being infiltrated with the first material to form the upper part as a single piece, said upper part being connected to the lower part by an integral material connection between the peripheral edge and the lower part.
