Abstract: A cooling device for a lighting unit of a motor vehicle, in particular for an LED headlight, at least comprising a metallic base plate, a heat sink, and a fan that is accommodated on a fan mount. The heat sink and the fan mount are situated on the base plate in such a way that an air flow that is generatable by the fan is directed onto the heat sink. The fan mount being made of a metal.

Abstract: An arrangement for making a flow uniform, having a housing, which is designed to limit the flow, wherein the housing has holes through which the flow flows, as a jet, into a space outside the housing, wherein the holes are spaced apart in such a way that it is not possible for jets coming from two adjacent holes to merge.

Abstract: A control valve for controlling a gaseous volumetric flow rate, in particular a steam volumetric flow rate, having a valve housing, a valve seat, and a valve throttle element which can be moved relative to the valve seat along a movement axis. The valve housing shapes the valve seat, and the movable valve throttle element has a throttle edge region which interacts with the valve seat. The control valve has multiple volumetric flow rate swirl elements which interact with the throttle edge region and which prevent or at least reduce shear layer instabilities in a shear layer between a wall jet region of the gaseous volumetric flow rate and a core flow region of the gaseous volumetric flow rate.

Abstract: A structure and method are provided for preventing or at least minimizing thermally-induced structural distortions, such as may occur when a steam turbine is cooling down. The steam turbine may include an inner housing and an outer housing. An intermediate space is formed between the inner housing and the outer housing, and sealing steam may be injected into the intermediate space to avoid the formation of temperature strata in the interspace and thus prevent the outer housing from bowing.

Abstract: A steam turbine arrangement and a method for operating a steam turbine, wherein the steam turbine is supplied with steam via a first valve in a first steam supply line and via a second valve in a second steam supply line. The valves are controlled asymmetrically so that in the event of unwanted vibrations measured by acceleration sensors one valve closes and the other valve opens in order to ensure the desired total mass flow.

Abstract: A turbine condenser includes an area with condenser tubes for liquefying waste steam from the steam turbine, a chamber formed by condenser walls for receiving the waste steam, and a diverted steam channelling system for channelling diverted steam into the chamber in the turbine condenser, wherein the diverted steam channelling system includes an annular nozzle extending into the turbine condenser, the outlet end of which has an uneven edge.

Abstract: A turbomachine is provided having an inflow segment which carries an inflow segment vane and bores, a partial mass flow arriving through these bores at a relief space and leading to a cooling system.

Abstract: A diversion station is provided. The diversion station makes it possible to particularly effectively cool diverted water vapor by mixing it with water. The diversion station includes a mixing device, which comprises a so-called static mixer that is substantially made of a wire mesh. The wire mesh is produced by at least one wire that is substantially interlaced into loops. In the intended installation situation, the mixer is installed upstream of a water injection with regard to a flow direction specified by the water vapor such that the mixture of water and water vapor flows through the loops.
