Claims43
An electric unit with at least one cooler structure and with at least one electric module comprising an electric component on a metal-ceramic substrate,
- wherein the at least one electric module comprises two metal-ceramic substrates, which consist of at least one ceramic layer which is provided on at least one surface side with a first, at least partially structured metallization,
- wherein the two metal-ceramic substrates with their side facing away from the first metallization are connected at least thermally with an active cooler respectively, wherein the electric component is provided between the two metal-ceramic substrates and is connected electrically with the first metallization of the two metal-ceramic substrates and is thermally connected with the first metallizations of both substrates, and
- wherein each of the first metallizations of the metal-ceramic substrates forms external electrical connections
- wherein for forming the external electrical connections a ceramic layer of the metal-ceramic substrate leads out with the structured first metallization through an outer surface of the module of the electric unit.
An electric unit with at least one ladder rung-like cooler structure, the electric unit comprises at least three flat active coolers, which extend parallel to each other and at a distance from each other between pipe sections for a supply and return flow of a coolant,
- wherein between two of the coolers respectively a module with at least one electric component is provided, which is connected at least thermally with both mutually adjacent coolers on two mutually opposing sides of the module,
- wherein the each module comprises at least two metal-ceramic substrates, which consist of at least one ceramic layer respectively, which are provided on at least one surface side with a first, at least partially structured metallization, and with their side facing away from the first metallization connected at least thermally with one of the two coolers,
- that the at least one electric component is provided between the two metal-ceramic substrates of the respective module and is connected electrically with the first metallization of the at least two metal-ceramic substrates and is thermally connected with the first metallizations of both substrates, and
- two modules are connected to form a chamber-like modular unit that can be pushed onto the coolers of a cooler structure.
An electric unit with at least one cooler structure and with at least one electric module comprising an electric component on a metal-ceramic substrate, wherein the at least one module comprises two metal-ceramic substrates, which consist of at least one ceramic layer, which is provided on at least one surface side with a first, at least partially structured metallization, that the two metal-ceramic substrates with their side facing away from the first metallization are connected at least thermally with an active cooler, and that the one electric component is provided between the two metal-ceramic substrates and is connected electrically with the first metallizations of the two metal-ceramic substrates and is thermally connected with the first metallizations of both substrates.
An electric unit consisting of an electric module, which comprises an electric component on a metal-ceramic substrate and at least one cooler, which is connected at least thermally with the electric module or with the metal-ceramic substrate and comprises cooling channels through which a coolant can flow, wherein the at least one cooler is formed by a flat profile of a metal material or plastic with a plurality of channels used as the cooling channels extending in the profile longitudinal direction.
An electric unit consisting essentially of at least one module, which comprises an electric component on a metal-ceramic substrate and at least one cooler, which is connected at least thermally with the electric module or with the metal-ceramic substrate and comprises cooling channels through which a coolant can flow, wherein the at least one cooler is formed by a tub-shaped cooler element forming a cooler interior through which the coolant can flow and by a cover element tightly sealing the cooler element on a side opposing the bottom.
