Patent number: 8333108Abstract: The present invention relates to the field of automotive heat exchanger assemblies, and, in particular, assemblies with cores with headers and end tanks and/or male and female connections. The present invention also relates to a method of making a positive leak path to determine leaks prior to employment of heat exchanger assembles. The present invention further relates to a method of determining whether or not a leak seal is temporary by providing a positive leak path at the point of assembly or initial evaluation or testing a heat exchanger.Type: GrantFiled: June 30, 2005Date of Patent: December 18, 2012Assignee: Valeo, Inc.Inventors: Jay Lorentz, Stephen Gunn, Eric Leroy, Nicolas Lelievre

Patent number: 7523782Abstract: There is disclosed a heat exchanger for transferring heat between at least two fluids and a method for forming the heat exchanger. The heat exchanger preferably includes one or more end tanks, one or more inlets and outlets, one or more tubes, one or more fins, and one or more improved baffle combinations including at least one single piece double baffle. The improved single piece double baffles act as part of a baffle system, with advantages over multiple-piece only double baffle systems due to being assembled in one piece.Type: GrantFiled: July 31, 2004Date of Patent: April 28, 2009Assignee: Valeo, Inc.Inventors: Jay Lorentz, Bradley A. Smith

Patent number: 7497245Abstract: A heat exchanger assembly includes a core with a header, an end tank and a joint between the header and the end tank. A seal between the header and the end tank is in an area at the joint between the header and the end tank. The seal normally produces a permanent seal except when a misalignment of the seal at the joint between the header and the end tank produces a temporary seal. At least one groove or channel is defined in the header or the end tank at the joint between the header and the end tank, for detecting the temporary seal. The at least one groove or channel extends beyond a highest point at which the temporary seal is formed. The groove or channel functions as a positive leak path between the temporary seal and the header and/or the end tank in the area at the joint between the header and the end tank.Type: GrantFiled: June 30, 2004Date of Patent: March 3, 2009Assignee: Valeo, Inc.Inventors: Jay Lorentz, Stephen J. Gunn

Patent number: 7059393Abstract: An improved heat exchanger for an automotive vehicle, comprising at least one end tank; and at least two heat exchangers including a plurality of spaced apart extruded metal tubes with fins between the spaced tubes. The heat exchangers are disposed so that their respective tubes and fins are generally co-planar with each other and are connected to the end tank. In preferred embodiments, the heat exchanger may include a bypass element.Type: GrantFiled: March 22, 2005Date of Patent: June 13, 2006Assignee: Valeo, Inc.Inventors: Lei Fang, Zaiqian Hu, Pascal Bonnet, Jason W. McKittrick, Jay Lorentz, David W. Baylor, Daniel R. Domen
