Patent number: 8365813Abstract: A switchable exhaust gas heat exchanger includes an exhaust gas feed line and an exhaust gas discharge for an exhaust gas stream; a first exhaust gas passage and a second exhaust gas passage; a switching valve configured to switch the exhaust gas stream between the first and second exhaust gas passages; and a heat exchanger through which a coolant flows which is arranged in the first exhaust gas passage. The second exhaust gas passage routes the exhaust gas stream past the heat exchanger to the exhaust gas discharge. The switching valve is configured to be switched as a function of the temperature of the coolant and is a proportional control valve. A switching threshold and a switching limit of the coolant determine flow of the exhaust gas stream through the first and second exhaust gas passages.Type: GrantFiled: June 28, 2010Date of Patent: February 5, 2013Assignee: Behr GmbH & Co.

Publication number: 20080202724Abstract: The invention relates to exhaust gas heat exchangers, as they are generally known, and to a sealing device which is especially suitable for using in exhaust gas heat exchangers. The inventive exhaust gas heat exchanger comprises connection points for the exhaust gas flow, for connecting the exhaust gas heat exchanger both to an exhaust gas supply line for supplying a hot exhaust gas and an exhaust gas withdrawal line for withdrawing the exhaust gas flow cooled in the exhaust gas heat exchanger. The exhaust gas flow flows through the exhaust gas heat exchanger in a bundle of exhaust gas guiding pipes in a flow direction. A coolant also flows through the exhaust gas heat exchanger, in a coolant flow. To this end, the exhaust gas heat exchanger is provided with at least one coolant supply connection and at least one coolant withdrawal connection. The coolant is guided in a coolant channel in the exhaust gas heat exchanger, inside which it flows around the bundle of exhaust gas guiding pipes.Type: ApplicationFiled: March 18, 2004Publication date: August 28, 2008Applicant: BEHR GMBH & CO.
