Various embodiments include stator for an electrical machine comprising: a stator winding; and a yoke with a plurality of slots. There are a plurality of conductor segments connected to one another, wherein each conductor segment has one respective axially internal inner section and two respective axially external outer sections. The respective inner section of each conductor segment is embedded into a respective slot. Ducts for coolant flow in the axial direction are formed at least in a portion of each of the slots. The stator defines, at least in a first axial end region, a first coolant chamber fluidically encapsulated from a surrounding area. The first coolant chamber surrounds at least a portion of the respective outer sections of each of the conductor segments situated in the first axial end region. The first coolant chamber is fluidically connected to the ducts to conduct coolant into and/or out of the ducts.

A super conductor is disclosed, in particular a high temperature super conductor of a synchronous machine, including a cooling circuit for a coolant. The liquefied coolant in the cold head provided with a condenser is guided to the super conductor which is to be cooled, in particular in the rotor of the synchronous machine and is returned to the condenser in a gaseous form. In order to guide the coolant from the condenser to the super conductor, pressure generated by a component of the coolant evaporated by a heat source is used.

A cooling device is disclosed for cooling a superconductor, wherein the cooling device includes a linear compressor for compressing a working medium and a cooling unit for providing a cooling power to a cryogenic coolant of the superconductor by expanding the working medium. The linear compressor includes two pistons of which at least one, preferably both synchronously relative to each other, are displaceable at a frequency and a stroke linear to the other piston, wherein a defined cooling power can be generated at a good efficiency so that the cooling device is suitable for use particularly in mobile installations, such as ships. To this end, according to at least one embodiment of the invention, the stroke of the at least one displaceable piston is controlled at a preferably prescribed target value.

In order to cool the windings, core and optionally the wall of the element () receiving the windings () and the core () as effectively as possible, conducting surfaces () are disposed inside said element in such a way that the flow of coolant initially passes along the windings (), followed by the limbs () of the core surrounded by the windings, and subsequently the other areas (). Said arrangement of conducting surfaces is particularly suitable for use with transformers having superconductive windings made of HTSL conductor material.

An injection-molded part (1) includes elevations (2) and/or depressions (12) arranged between integrated printed conductors (4). If the elevations (2) or depressions (12) are uncoated and thus electrically insulating, they increase the effective voltage clearances between the printed conductors (4) and the components (3) arranged next to the printed conductors (4). The geometric distances can then be reduced. Alternatively, by electroconductively coating the elevations (2), electric and magnetic shielding is achieved in a simple manner. A cover (6) is provided as a top of a box which uses elevations (2) as side walls. A tapering portion (5) connects coatings (7,7') of the cover (6) and elevations (2) via a printed conductor (8) running diagonally across the tapering portion (5).

An insulating part for an electronic device includes a first metallized outer surface capable of cooling one or more electronic components disposed on the insulating part. The insulating part also includes one or more additional metallized outer surfaces, such as a set of cooling ribs, to provide improved cooling for the electronic components. These additional outer surfaces are coupled electrically and thermally to the first metallized outer surface, and to each other by recesses containing a heat transfer element, such as a metallization or a soldered connection. Thus, heat transferred to the first outer surface is further dissipated among the several additional cooling surfaces.

An insulating part for an electronic device includes a body having a metallized outer surface and a heat sink arranged within the body. The heat sink is thermally coupled to an electronic component and to the metallized outer surface, and may also be either electrically coupled or electrically isolated from the electronic component. The insulating part is preferably made of plastic by an injection-molding process, while the heat sink is preferably a metal block integrally formed within the insulating part.

Insulating part with integral cooling element

Previously known circuit boards as components of devices having a housing have a plastic rear wall of the housing and the circuit board creates a connection between at least two printed circuit boards in the housing. Furthermore, processes for the production of three-dimensional printed circuits are known. Taking these as a point of departure, a one-piece circuit board as an integral portion of the housing of the device is created. One that not only produces the function of an electrically-conductive connection between the aforementioned printed circuit boards, but also serves as a mounting for the printed circuit boards, i.e., it can assume mechanical functions. This is solved by virtue of the fact that the rear wall (1) of the housing consists of plastic and embodies a circuit board having metallized strip conductors (2) and flat surfaces (3) that conduct electricity. And, on the interior of the rear wall (1), protruding connectors are moulded. The latter are themselves metallized, and they are, by dint of the strip conductors (2) and/or the flat surfaces (3), connected with one another so as to conduct electricity. The printed circuit boards ( 5) may be connected electrically to the connective media (4). Such circuit boards may be used in devices that provide automation.

Device housing having an integrated circuit board

An electronic module includes two printed-circuit boards which are equipped with hybrid assemblies. The electronic module takes up only a small amount of space and, at the same time, efficiently dissipates the heat loss caused by the hybrid assemblies. The hybrid assemblies are arranged in such a manner that they can be interspersed with one another, similar to a sandwich-type construction. The interspersing provides duct-type, perpendicularly aligned interspaces between the hybrid assemblies, allowing the heat loss to be dissipated in a chimney-like fashion.

Electronic module

An automating assembly for electrical installations comprises a plurality of input and output modules each detachably fastened to a respective modular module carrier removably attached to a support bar. The module carriers each include an integrated circuit connectable to the integrated circuits of adjacent module carriers by means of rigidly mounted plug strips and cooperating jack strips connected to the integrated circuits of the module carriers via flat flexible cables. Each modular module carrier is connected to a respective terminal block for the coupling of external wires to the automating assembly. The module carriers are designed to facilitate the removal of individual module carriers for applications in which a reduced number of input and output modules is required.
