A system for mounting at least one cylindrical electrolytic capacitor on a heat sink, the heat sink having at least one bore for at least partially receiving a cylindrical electrolytic capacitor, and the bore partially or fully encompassing the cylindrical electrolytic capacitor once it has been received, wherein lateral surfaces of the cylindrical electrolytic capacitor are mechanically and thermally connected to surfaces forming the bore. The system providing thermal cooling of the electrolytic capacitor and enabling substantially uniform thermal cooling of the capacitor. A method for producing a connection between the at least one cylindrical electrolytic capacitor and the heat sink, and to a connection, obtainable by the method, between the at least one electrolytic capacitor and the heat sink.

Cooling of electrolytic capacitors in electrical climate compressors

The invention which relates to an EMC filter () addresses the problem of specifying an EMC filter () that is simple of structure, cost-effective and temperature resistant. This problem is resolved thereby that the core of the choke () is comprised of one or two core parts (), that at least one first planar or convex heat transfer area () is located on an outside of the core and that the core with this first planar or convex heat transfer area () is disposed on a housing () of the refrigerant compressor, wherein the housing () in the region of the first planar or convex heat transfer area () is implemented planar or concave.

EMC-filter

The invention, which relates to an arrangement for current measurement at a current lead-through, addresses the problem of specifying an arrangement for current measurement by means of which a reliable, galvanically isolated measurement of motor phase currents can be carried out, wherein the space requirement of the arrangement is reduced. This problem is resolved thereby that the sensor is a measuring coil and that the measuring coil is disposed on the lead-through contact such that it is galvanically isolated from the same.
