Publication number: 20150357692Abstract: Disclosed embodiments include thermoelectric-based thermal management systems and methods configured to heat and/or cool an electrical device. Thermal management systems can include at least one electrical conductor in electrical and thermal communication with a temperature-sensitive region of the electrical device and at least one thermoelectric device in thermal communication with the at least one electrical conductor. Electric power can be directed to the thermoelectric device by the same electrical conductor or an external power supply, causing the thermoelectric device to provide controlled heating and/or cooling to the electrical device via the at least one electrical conductor. The thermoelectric management system can be integrated with the management system of the electrical device on a printed circuit substrate.Type: ApplicationFiled: January 28, 2014Publication date: December 10, 2015Inventors: Alfred Piggott, Dmitri Kossakovski, Todd Robert Barnhart

Patent number: 8931584Abstract: A seal member may include a base portion, a plurality of deflector portions, and an expansion portion. The base portion may include a plurality of tabs adapted to be mounted to a heat exchanger. The plurality of deflector portions may each extending from a corresponding one of the plurality of tabs and manipulate a flow of fluid proximate the heat exchanger. The expansion portion may be disposed between adjacent deflector portions and may be expandable in response to exposure to heat between a first position at which the adjacent deflector portions are a first distance apart from each other and a second position at which the adjacent deflector portions are a second distance apart from each other.Type: GrantFiled: January 18, 2011Date of Patent: January 13, 2015Assignee: DENSO International America, Inc.Inventors: Matthew Sasina, Alfred Piggott

Patent number: 8789805Abstract: A bracket for stabilizing a heat exchanger has a base member extending between first and second ends. An aperture at the first end of the base member receives a fastener. The bracket is fixedly secured to a vehicle through the fastener. A flex zone extends between the first and second ends of the base member. The flex zone is movable between a first, relaxed position and a second, flexed position.Type: GrantFiled: March 31, 2010Date of Patent: July 29, 2014Assignee: DENSO International America, Inc.Inventors: Alfred Piggott, Simon Kehimkar

Patent number: 8397797Abstract: A heat exchanger with multi-flow capabilities includes a pair of intermediate tanks located between a pair of header tanks. An open gap is provided between the two intermediate tanks. A first plurality of tubes extend between the header tanks. A second plurality of tubes extend between one of the header tanks and one of the intermediate tanks. A third plurality of tubes extend between the other header tank and the other intermediate tank. In a two flow system, the two intermediate tanks are in fluid communication through a flexible jumper tube. In a three flow system the two intermediate tanks are isolated from each other. The open gap between the intermediate tanks allows for the uneven heat expansion between the various fluid flows.Type: GrantFiled: March 31, 2010Date of Patent: March 19, 2013Assignee: DENSO International America, Inc.Inventor: Alfred Piggott

Publication number: 20120095670Abstract: A method of controlling an internal combustion engine of a vehicle may involve turning on the internal combustion engine, stopping the vehicle or while the vehicle is approaching a known potential stopping location, inquiring whether a first predetermined quantity of data samples exists in memory and further inquiring whether the first predetermined quantity of data samples corresponds to a specific time of day, of a specific day of the week, of a specific month of the year, for a specific GPS location, inquiring whether a second predetermined quantity of data samples exists in memory for the specific time of any day of the week for the specific GPS location, inquiring whether a third predetermined quantity of data samples exists for any single, specific time of day for any day of the week for the specific GPS location. Depending upon the reply to each of the above inquiries, the method may include turning off the internal combustion engine.Type: ApplicationFiled: October 13, 2010Publication date: April 19, 2012Applicant: DENSO INTERNATIONAL AMERICA, INC.Inventor: Alfred Piggott
