  • Patent number: 10295264
    Abstract: A fluid/air heat exchanging device (2) has fluid-conducting outside collecting chambers (6, 10) having an inlet (8) or outlet (12) and being connected to one another via duct-shaped fluid guides (14) that control the temperature of a fluid flow by an air flow. The air flows in duct-shaped air guides separated from the fluid guides (14). A further collecting chamber (18; 20, 22) is inserted between outside collecting chambers (6, 10). The further collecting chamber (18; 20, 22) is arranged parallel to the outside collecting chambers (6, 10). All the fluid guides (14) are connected to the further collecting chamber and one of the outside collecting chambers (6, 10).

  • Publication number: 20160341482
    Abstract: A heat exchanging device (2), in particular a fluid/air heat exchanger, having individual fluid-conducting collecting chambers (6, 10) which in each case have an inlet (8) or outlet (12) for fluid supply and discharge and which are connected to one another via duct-like fluid guides (14) which control the temperature of, in particular cool, a fluid flow during operation of the device by means of an air flow which flows in duct-like air guides which are separated from the fluid guides (14) in a medium-tight manner, is characterized in that, in order to construct the overall heat exchanging device (2), at least one further collecting chamber (18; 20, 22) is inserted between collecting chambers (6, 10) which are arranged on outer sides which lie opposite one another, which further collecting chamber (18; 20, 22) is arranged parallel to the collecting chambers (6, 10) which lie on the outside, and into which further collecting chamber (18; 20, 22) all the fluid guides (14) which are connected to a collecting cham

  • Publication number: 20090278465
    Abstract: A power conversion unit converts an AC voltage into substantially constant DC current. The power conversion unit can be placed into an end cap of an LED lighting unit, to power LED modules. The power conversion unit uses capacitors and a bridge rectifier to perform the power conversion. The capacitors and bridge rectifier are selected to configure the power conversion and to produce the desired variable voltage substantially constant DC current.

  • Publication number: 20060171378
    Abstract: An IP video telephone includes a video display for displaying received video signals and a speaker for playing received audio signals. A gateway processor connects the IP video telephone to an external IP network and receives the received audio and video signals. A video processor processes the received video signals while an audio processor processes the received audio signals. Each of the gateway processor, the video processor and the audio processor are interconnected via an ethernet network.
