Patent number: 6993838Abstract: The invention relates to a collector tube (1) for a heat transfer unit. The tube comprises one or several slits (3d) on the periphery thereof, whereby said slits are formed by a punch press without an inner die or by high-pressure shaping for inserting a respective flat tube. The invention also relates to a method for producing said collector tube (1). According to the invention, a collector tube (1) is provided with an outer radius (D/2) to tube wall thickness (s) ratio of less than 5. The slits (3d) are introduced preferably parallel to, or at an acute 2 angle to the longitudinal axis of the tube.

Patent number: 6971440Abstract: The invention relates to a heating or air-conditioning system for a motor vehicle, by which individual zones of the vehicle interior can be supplied with separately temperature-controlled air. An improved heating or air-conditioning system, which requires just a small amount of installation space, feeds differently temperature-controlled air to a plurality of air-conditioning zones. Despite the small amount of installation space, optimum mixing of cold air and warm air takes place in the heating or air-conditioning system, with the result that the air emerging from air-outlet openings in a respective air-conditioning zone have a constant temperature over the outlet cross section.Type: GrantFiled: July 24, 1998Date of Patent: December 6, 2005Assignee: Behr GmbH & Co.Inventors: Oliver Beck, Michael Forster, Christian Grommer, Norbert Wocht

Patent number: 6957689Abstract: A heat exchange arrangement for a vehicle has at least two heat exchangers exposed to the action of ambient air. One of the heat exchanger is coolant cooler and the other one is a charge-air coolant. Each of these coolers has tubes through which liquid or gas flows and heat dissipating ribs connected to the tubes. The coolant cooler is positioned upstream of the charge-air cooler in the air-flow direction. The charge-air cooler has an overlapping region in which the coolant cooler and the charge-air cooler overlap one another and a non-overlapping region in which the coolant cooler projects substantially perpendicularly to the cooling air flow direction. The non-overlapping region is formed at least in the charge-air outlet region and is cooled directly by ambient cooling air. The overlapping region is cooled by the ambient cooling air that has passed through the coolant cooler, which is positioned immediately upstream of the overlapping region of the charge-air cooler.Type: GrantFiled: December 2, 2002Date of Patent: October 25, 2005Assignee: BEHR GmbH & CO.Inventors: Peter Ambros, Peter Griesheimer, Reinhard Kull, Eberhard Pantow

Patent number: 6953325Abstract: A safety device limits the pressure in an axial-piston compressor with variable piston displacement. The compressor has as wobble plate or swash plate whose tilt angle can be variably controlled by the pressure differential between the high pressure in the discharge pressure zone and the pressure in the piston-drive chamber. The safety device consists of a valve arranged in a connector channel between the discharge pressure zone and the pressure zone of the piston-drive chamber. When the discharge pressure exceeds a given pressure limit, the safety device responds by allowing an increased flow of pressure medium from the discharge pressure zone to the piston-drive chamber. The influx of pressure medium into the piston-drive chamber causes a reduction of the tilt angle of the swash plate or wobble plate.Type: GrantFiled: January 6, 2003Date of Patent: October 11, 2005Assignees: LuK Fahrzeug-Hydraulik GmbH & Co., KG, Behr GmbH & Co.Inventors: Georg Weber, Michael Sickelmann, Tilo Schäfer, Christoph Walter, Hans-Joachim Krauss, Harald Raiser, Frank Obrist
