Patent number: 10436526Abstract: A heat exchanger may include a plate, a seal and a cover. The plate may have at least two receiving grooves having a respective groove base, an intermediate region disposed in a plane between a plurality of rim holes, and a ramp extending between the intermediate region and the respective groove base of the at least two receiving grooves. The seal extends in the at least two receiving grooves. The ramp may be rounded at a transition to the receiving grooves with a first radius and at a transition to the intermediate region with a second radius, and the ramp may be inclined between 20°<?<65° relative to the intermediate region or has an S-shaped progression. An inflection point of the plate may be arranged in a region from 10% to 80% of a height difference between the intermediate region and the respective groove base.Type: GrantFiled: December 2, 2014Date of Patent: October 8, 2019Assignee: Mahle Behr GmbH & Co. KGInventors: Harald Bronner, Markus Gutjahr, Markus Huebsch, Claus Augenstein, Reinhard Kull, Stefan Weise, Jens Ruckwied, Jochen Haeussermann

Patent number: 10107571Abstract: A gas-cooled heat exchanger, in particular a direct intercooler, for cooling of a fluid which flows through the heat exchanger, with a heat transfer block featuring a plurality of flow channels, with a first collection chamber and a second collection chamber. The collection chambers are fluidically connected with one another via the flow channels and the outside of the heat transfer block can be perfused by gas. In the direction of the perfusion, a screen is arranged in front of the heat transfer block for the prevention of flow in certain areas around the flow channels of the screen. One of the collection chambers features a vent for discharge of condensate of the fluid which can be sealed from or released into the surrounding area of the heat exchanger.Type: GrantFiled: September 14, 2015Date of Patent: October 23, 2018Assignee: MAHLE International GmbHInventors: Claus Augenstein, Christian Oberlechner, Markus Reck, Wolfgang Reeb, Stefan Weise

Patent number: 8439252Abstract: A method for bonding two partially form-fitting surfaces of two metal bodies which contain the same metal is carried out by generating a first layer on the surface of a first one of the two bodies, the first layer containing a mixture of the metal and the oxide of the metal; generating a second layer on the first layer, the second layer containing the metal but less oxide of the metal than does the first layer; placing the partially form-fitting surfaces of the two metal bodies adjacent to each other; heating the bodies placed adjacent to each other to a temperature which lies in a target range below the melting point of the metal and above the eutectic temperature of the eutectic of the metal and the metal oxide; and holding the temperature within the target range over a predetermined or a controllable duration of time.Type: GrantFiled: October 31, 2007Date of Patent: May 14, 2013Assignee: Excelitas Technologies GmbH & Co KGInventors: Ulrich Traupe, Stefan Weise, Pellegrino Ballacchino, Edgar Spandl

Patent number: 7896065Abstract: The invention relates to a heat exchanger for motor vehicles, especially for utility vehicles. The heat exchanger can include a heat exchanger unit that includes tubes having tube ends and ribs disposed between the tubes, and collecting tanks disposed on both ends and produced by internal high pressure forming for introducing and discharging a medium. The collecting tanks can include bottoms with openings for receiving the tube ends, covers, and inlet and outlet tubes.Type: GrantFiled: September 30, 2004Date of Patent: March 1, 2011Assignee: Behr GmbH & Co. KGInventors: Claus Augenstein, Karsten Emrich, Martin Engelhardt, Klaus Förster, Franco Ghiani, Daniel Hendrix, Scott Horoho, Reinhard Kull, Andre Schairer, Bernd Weiler, Stefan Weise
