摘要： PTC thermistors are used in reversible short circuit current limiters, in particular in series connection with electrical valves and/or capacitors. An electrically insulated, thermally conductive insulation or ceramic layer (20) is in contact electrically and with good thermal conduction via a first main surface with a metallic cooling element (25). A second main surface of the ceramic layer (20), opposite the first main surface, is covered with an electrically insulating thermal-conduction layer (21) having a thickness in the range from 10 .mu.m-100 .mu.m. Meandering tracks (16) of the resistive body of the PTC thermistor (5) are pressed between this thermal conduction layer (21) and an electrically insulating, preferably thermally conductive, flexible high-temperature stable polymer film (22). In order to provide pressure, a pressure compensation cushion (23) on which a force (F) orthogonal to the second main surface of the ceramic layer (20) acts, may be provided. The pressure compensation cushion (23) is filled with a dielectric or electrically conductive fluid (24) having a boiling temperature above preferably 150.degree. C. The resistive track (16) may also be embedded in a filled polymer matrix, it being possible for geometrically congruent resistive tracks to be opposite on a ceramic layer.

摘要： A liquid-cooled high-load resistor includes an element carrier having an inlet and an outlet, a break-through and a first and second electrical terminal connection, and one resistor element, respectively, on its flat sides. The active parts of the resistor elements are electrically connected in series by means of the break-through in the element carrier and are electroconductively connected to an electrical terminal connection of the element carrier. The liquid-cooled high-load resistor further includes two covers that each cover a flat side of the element carrier, to form an enclosed space between the cover and the flat side of the element carrier. The enclosed space is subdivided so as to provide a free space in the area of the inlet, the outlet, and the break-through, and to provide a cooling channel that embeds the active part of the resistor element. Thus, one obtains a liquid-cooled high-load resistor of a relatively small size, whose self-inductance is minimal and which is capable of being loaded with a high voltage and of being operated at high power levels that entail high losses.

摘要： A liquid-cooled electrical assembly containing an arrangement for cooling at least one electrical component under current flow. In this assembly, liquid coolant flows into an inlet in the cooling arrangement and the heated-up coolant is removed through an outlet. In order to increase the power handling capacity of such an arrangement over that of known arrangements having similar dimensions, a cooler is constructed from sheet-like or layer-like cooling elements, each of which have an entrance or inlet opening and an exit or outlet opening for the liquid coolant. The cooling elements are stacked together in alternating fashion with the electrical components so that the entrance openings and exit openings of the cooling elements are in direct connection with the inlet and outlet of the whole cooler. This kind of assembly will find many preferred applications when they are constructed as resistors or power semiconductors.

摘要： A method of making a light weight compact power resistor is disclosed comprising the steps of positioning a flexible nonconductive fluid conduit in a substantially straight path, threading a lead having clamping means completely through the interior of the conduit, attaching the clamping means to one end of a flexible conductive strip and drawing the strip axially through the conduit in a substantially straight path by means of the lead, coiling the conduit containing the conductive strip through at least 360* in a plane substantially perpendicular to the width of the conductive strip and fixedly attaching the resulting coil to a rigid support in a manner sufficient to enable flexure of the fluid conduit and conductive strip under the influence of pressure variations in a cooling fluid passed into and through the fluid conduit.
