Patent number: 11832425Abstract: A support for at least one electrical component includes a heat sink having a heat sink surface and two opposing lateral walls protruding from the heat sink surface. The heat sink includes a base body made of aluminum and a copper layer as a heat spreading layer which forms the heat sink surface. The copper layer is produced together with the base body through continuous casting, or with the copper layer being applied additively through cold gas spraying to a surface of the base body. Two spaced-apart sealing blocks lie on the heat sink surface, with each of the two sealing blocks extending between the two lateral walls and contacting the two lateral walls. A support structure is arranged on the heat sink surface between the two sealing blocks.Type: GrantFiled: August 21, 2020Date of Patent: November 28, 2023Assignee: Siemens AktiengesellschaftInventors: Daniel Kappauf, Lutz Namyslo

Patent number: 11689116Abstract: A substrate and a first circuit board each have an upper side and a lower side. The substrate lower side is connected to a cooling body. On the upper side of the substrate, first electronic switching elements connect an alternating current potential at a phase terminal to a high direct current potential at a first potential terminal and to a low direct current potential at a second potential terminal. Second electronic switching elements connect the alternating current potential to a middle direct current potential at a third potential terminal. The substrate is spaced from the first circuit board under the first circuit board lower side. The upper side of the substrate faces toward the first circuit board. The second switching elements are at least on the upper side of the first circuit board, possibly additionally also on the lower side of the first circuit board.Type: GrantFiled: August 13, 2021Date of Patent: June 27, 2023Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Jens Schmenger, Lutz Namyslo
