Temperature-control arrangement for a microelectric system

A microelectric system, comprising:

• at least one object to be temperature-controlled;
• and
• at least one temperature-control arrangement, including:
• a closed channel system, which includes at least one channel for guiding an electrically and thermally conductive medium and is thermally coupled to the at least one object of the microelectric system to be temperature-controlled, and
• a magnetohydrodynamic pump with a plurality of magnetohydrodynamic modules, each of the magnetohydrodynamic modules including an electrode device with two electrodes and a magnet device which generates a magnetic field, wherein at least two of the magnetohydrodynamic modules are configured as pump modules and are electrically connected in series, wherein, in each of the pump modules, a first electrode of the electrode device introduces an electric current flow with a specified current density at at least one channel portion into the electrically and thermally conductive medium and a second electrode of the electrode device conducts the electric current flow at the at least one channel portion out of the electrically and thermally conductive medium so that cooperation of the electrically and thermally conductive medium, guided in the closed channel system, with the introduced electric current flow and with the generated magnetic field generates a Lorentz force, which in a targeted manner accelerates the electrically and thermally conductive medium in the at least one channel portion, and a resulting pressure build-up brings about a desired volume flow of the electrically and thermally conductive medium through the at least one channel of the closed channel system, wherein the volume flow of the electrically and thermally conductive medium brings about a temperature control of the at least one object to be temperature-controlled, wherein the electrically and thermally conductive medium transfers heat to the at least one object to be temperature-controlled during a heating process or absorbs heat from the at least one object to be temperature-controlled during a cooling process.
