摘要： The present invention discloses a cooling trough comprising an unflat surface, surrounding an opening of the cooling trough, configured with a height essentially decreasing inwardly. At least one supporting line, running around the opening of the cooling trough, is formed on the unflat surface. The at least one supporting line contacts a baseplate of a power module after the baseplate is attached to the unflat surface of the cooling trough. In addition, the present invention also discloses a cooler comprising the cooling trough and a power module assembly comprising the cooler.

摘要： The invention relates to an electronic power system (1) comprising at least one electronic power module (2). The electronic power module (2) comprises a base plate (3) and at least one heat generating component arranged on a first side of the base plate (3). The electronic power module (2) comprises a cooling structure (4) transporting heat away from the electronic power module (2) via a coolant that is guided by the cooling structure (4). The cooling structure (4) is arranged on a second side (5) of the base plate (3) opposite to the first side. Task of the invention is to provide an electronic power system (1) with an improved cooling. According to the present invention this task is solved in that the cooling structure (4) is integrally formed with the base plate (3).

摘要： A flow distribution module (1) for distributing a flow of fluid over a surface to be cooled is disclosed. The flow distribution module (1) comprises a housing (2) and a cover plate (3). The housing (2) defines at least one flow cell (5), the flow cell(s) (5) being positioned in such a way that a flow of fluid flowing through a flow cell (5) from an inlet opening (6) to an outlet opening (7) is conveyed over the surface to be cooled, each flow cell (5) being formed to cause at least one change in the direction of flow of the fluid flowing through the flow cell (5). The cover plate (3) is arranged adjacent to the flow cell(s) (5) and defines the surface to be cooled. At least a part of the surface to be cooled defined by the cover plate (3) is provided with a surface pattern (8) of raised and depressed surface portions.

摘要： The present invention discloses a cooling trough comprising an unflat surface, surrounding an opening of the cooling trough, configured with a height essentially decreasing inwardly. At least one supporting line, running around the opening of the cooling trough, is formed on the unflat surface. The at least one supporting line contacts a baseplate of a power module after the baseplate is attached to the unflat surface of the cooling trough. In addition, the present invention also discloses a cooler comprising the cooling trough and a power module assembly comprising the cooler.
