Matthias Banzhaf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6837194
    Abstract: The motor vehicle cooling system (10) contains a fan (12) with which at least one cooler (13) is associated. Provision is made for the fan (12) to be in the form of a centrifugal blower with an air guiding housing (18).
    Type: Grant
    Filed: August 19, 2002
    Date of Patent: January 4, 2005
    Assignee: BEHR GmbH & Co.
    Inventors: Matthias Banzhaf, Wolfgang Kramer, Reinhard Kull, Eberhard Pantow, Wolfgang Reeb, Annegret Tillmann
  • Patent number: 6792898
    Abstract: The invention relates to a coolant circuit for a motor vehicle having an engine and a radiator. The coolant circuit includes an exhaust gas heat exchanger and enables engine coolant coming from the radiator to be supplied directly to the exhaust gas heat exchanger. In a preferred embodiment, coolant coming from the radiator and/or from the engine can be selectively supplied to the exhaust gas heat exchanger via a changeover device.

  • Patent number: 6269870
    Abstract: In a heat exchanger used especially as an exhaust heat exchanger, provision is made for tube sheets, the tubes of a tube bundle, and a housing to be shaped from stainless steel sheets. The tube sheets are formed as deep-drawn and stamped parts, each of which has a circumferential wall that projects outward beyond the ends of the tubes in the tube bundle. The walls are welded to the housing, and each of the walls is abutted by a diffuser.

  • Patent number: 6213105
    Abstract: A device for exhaust recycling for an internal combustion engine with an exhaust cooler has a valve that determines the quantity of exhaust that is recycled and is adjustable by an adjusting element. Provision is made for the exhaust cooler and the valve to connect to one another directly and to form a module.

  • Patent number: 5215044
    Abstract: A cooling system for a vehicle having an internal-combustion engine has a plurality of cooling circuits with heat exchangers for each circuit. The temperatures of different cooling media are measured and processed in a switching device to form an output signal which serves to control a fan. In this way, the air flow through the heat exchangers can be varied depending on measured temperature conditions. Individual capacity control of each cooling circuit is possible, thereby preventing unfavorable operating conditions in the individual circuits. The cooling capacity demand of the individual cooling circuits is determined by a central control unit which receives signals from temperature sensors in each circuit. The central control unit includes a microprocessor. Each cooling circuit has an actuating means for individually controlling the capacity of the relevant heat exchanger.
