  • Publication number: 20080266047
    Abstract: A power resistor module for electrical circuits has at least one resistor element and at least one housing element. The at least one resistor element is mounted at least section-wise between two electrically insulating, thermally conductive insulation elements in the housing element. The insulation elements at least section-wise abut against the at least one housing element. Methods for producing an electrical power resistor module for an electrical circuit include compressing, at least one resistor element with two electrically insulating, thermally conductive insulation elements. At least one of the two insulation elements is pressed at least section-wise against a housing element. If a wire is used as the resistor element, the use of possible fillers such as magnesium oxide may be waived by providing that the wire abuts at least section-wise against at least one of the two insulation elements during the compression.

  • Patent number: 7335855
    Abstract: An electric PCB heating component for a heating electric component is coupleable to an electronic circuit board. The PCB heating component includes a fastening element, a heating element for generating thermal energy, and a heating body. The heating body emits thermal energy via a heat radiating surface. For a low cost PCB heating component, the heating element is a PTC heating element. A plurality of heating projections of the heating element cooperate to form a relatively large heat radiating surface such that thermal energy can be emitted in a substantially directional mode. The heating projections can be convection or radiation elements.

  • Publication number: 20070157602
    Abstract: A tank system can provide a predetermined cold start volume (VKS) of an operating liquid required by a liquid consumer after a cold start. The tank system can provide a urea solution to an SCR catalytic converter. The tank system includes a main tank with a filling opening through which the interior of the main tank can be filled with operating liquid. To melt a predetermined volume of the frozen liquid in a fast, efficient and complete manner, a melting device is provided. The melting device includes a melt tank which encloses a melting space and which comprises an inlet opening through which the melting space can be filled with the operating liquid from the interior of the main tank. The melting device includes a cold start heater for melting frozen liquid in the melting space. The melting space is at least as large as the cold start volume (VKS) and is smaller than the interior of the main tank.

  • Publication number: 20070003458
    Abstract: Heating device for the heating and gasification of urea or an urea solution, particularly for internal combustion engines, wherein said heating device is designed for installation in a gas line extending in a direction of flow and wherein said heating device has at least two gas-permeable heating surfaces that are spaced apart from each other in the direction of flow and that define a heating chamber. In order to create an improved heating device for stable urea gasification in an exhaust gas line that guarantees a uniform temperature distribution in the heating room as well as a quick response time, according to the invention an inlet opening is provided that discharges into the heating chamber between the at least two heating surfaces and through which the urea or urea solutions can be fed into the heating chamber.

  • Publication number: 20060289477
    Abstract: The invention relates to a folded heater element and a method of manufacturing a through-flow spatial structure in a folded heater element of a track material of a heater substance lying in an initial surface, whereby in the track material a heater meander is produced by parting the track material into single heater limbs connected to one another at the ends at connection zones and the heater meander is shaped out of the initial surface to form the through-flow spatial structure. In order to improve folded heater elements and their manufacturing methods such that they can be manufactured more economically and with a more flexible spatial structure, it is provided according to the invention that at least some connection zones are offset with respect to other connection zones and in achieving this the heater limbs connected to the connection zones are moved relative to one another and thereby a heater network is produced from the heater limbs.
