Patent number: 11795850Abstract: An exhaust gas treatment device for arranging in an exhaust gas section of a motor vehicle that includes a heating disk which is assigned to an exhaust gas aftertreatment component. The heating disk is configured by way of a flat heating element and a holder which is coupled to the former. The holder extends over the cross-sectional area of the heating element, and the holder itself is of disk-shaped configuration. The inner face of the heating disk is configured by way of arcuate spokes which are coupled irregularly to one another.Type: GrantFiled: February 10, 2022Date of Patent: October 24, 2023Assignee: BENTELER AUTOMOBILTECHNIK GMBHInventors: Elmar Grussmann, Ulrich Rusche

Patent number: 11633796Abstract: A plate heat exchanger has two metal plates brought into abutment, with a solder material between the plates. The plates are heated up to a first temperature. The plates are placed into a mold, the mold surfaces of which have cavities for envisaged channel structures. Channel structures are formed by local internal pressure forming of at least one plate under pressurization by the tool. The plates are heated up to a second temperature. The plates are solder bonded at the abuted surfaces. A plate heat exchanger has two metal plates, wherein channel structures have been formed in at least one plate and the plates are bonded to one another by soldering away from the channel structures. Eutectic microstructures having a longest extent of less than 50 micrometers are formed in the solder layer.Type: GrantFiled: December 7, 2021Date of Patent: April 25, 2023Assignee: BENTELER AUTOMOBILETECHNIK GMBHInventors: Max Boehnke, Ulrich Huschen, Elmar Grussmann, Ulrich Rusche, Jochem Grewe

Patent number: 9494055Abstract: The invention provides an exhaust heat utilization device for a combustion engine with an exhaust heat utilization circuit, in which a working medium circulates. An evaporator is arranged in the exhaust heat utilization circuit for evaporating the working medium, which can be supplied with exhaust gas of the combustion engine, with an expansion machine arranged in the exhaust heat utilization circuit downstream of the evaporator for expanding the working medium. A condenser is arranged in the exhaust heat utilization circuit downstream of the expansion machine for condensing the working medium. A delivery device is arranged in the exhaust heat utilization circuit downstream of the condenser for driving the working medium in the exhaust heat utilization circuit and with a heat storage unit. The device is given an improved functionality when the heat storage unit is incorporated in the exhaust heat utilization circuit and can be supplied with working medium.Type: GrantFiled: May 17, 2012Date of Patent: November 15, 2016Assignee: Eberspaecher Exhaust Technology GmbH & Co.
