Abstract: A temperature-control arrangement for a microelectric system, and a microelectric system. The temperature-control arrangement includes a closed channel system, which includes at least one channel for guiding an electrically and thermally conductive medium and is thermally coupled to at least one object to be temperature-controlled of the microelectric system, and a magnetohydrodynamic pump with a plurality of magnetohydrodynamic modules, which each include an electrode device with two electrodes and a magnet device, which generates a magnetic field, wherein at least two magnetohydrodynamic modules are designed as pump modules and are electrically connected in series.

Abstract: A cooling device for the redundant cooling of a control unit for a vehicle. The control unit has a first electronic component and a second electronic component that is redundant with respect to the first electronic component. The cooling device has a first cooling circuit for cooling the first electronic component and a second cooling circuit, fluidically separated from the first cooling circuit, for cooling the first and/or second electronic component.

Abstract: A carrier system for a high-frequency antenna having at least two electrodes situated at a predefined distance from one another and implemented as essentially flat, a dielectric being situated between the at least two electrodes, is distinguished in that the at least two electrodes are situated on a frame part which is as difficult to deform as possible. The frame part preferably has recesses or openings in such a way that air having ?r=1 is essentially situated between the at least two electrodes as the dielectric.
