Abstract: 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).

Abstract: A flow distributor (1) is provided for distributing a heat transporting fluid flow (2) of an electrical component across a surface to be cooled and/or heated by the fluid. The distributor includes at least one flow channel configured to direct the fluid flow across the surface, the flow channels being delimited on either side by walls (4) so as to form a path (6) for the fluid flow (2) within the flow channels (3), and comprising wall sections (5) extending into the at least one flow channel (3); and at least one of the wall sections (5) includes at least one bypass passage (7) to connect two adjacent spaces (8) separated by the wall section (5) where the at least one bypass passage (7) extends from one side of the wall section to the other one with an inclined orientation (10) so as to create a short circuit flow (9) for apart of the fluid flow (2).

Abstract: A resistance pressure welding device includes a mounting to support a flange and at least one exhaust pipe to be welded to the flange and arranged in a flange opening of the flange, with the exhaust pipe having an end in the form of an outwardly directed collar. The collar is pressed against the flange by an inner electrode which is movable in an axial direction of the exhaust pipe to press. An outer electrode is placed in spaced-apart surrounding relationship to the inner electrode, and movable in the axial direction of the exhaust pipe against the flange from the same side as the inner electrode so that the welding current can be conducted across the contact surfaces of the collar and the flange.

Abstract: A method of deforming an initial pipe having a circular cross-section into an U-shaped section and a device for carrying out the method wherein the inner surface of one half of the initial pipe rests in a positively engaging manner against the inner surface of the opposite half of the pipe, with the exception of lateral loop-shaped ear portions. The initial pipe is secured in its position by mandrels inserted in the ends of the pipe. Initially, the initial pipe is with its lower half at least over areas thereof supported by an abutment and the top half of the initial pipe is pressed in by a ledge-like top die with a convexly curved front portion located opposite the abutment until the top half of the initial pipe is pressed in until it makes contact with the diametrically oppositely located bottom half of the pipes so as to produce a U-shaped top half.
