Patent number: 9587888Abstract: An internal heat exchanger assembly for an air conditioning system, having a housing defining a cylindrical with opposing ends. The ends are sealed with end caps having inlets/outlets. A helical coil tube is coaxially disposed within the cylindrical cavity, in which the helical coil includes two tube ends extending in opposing directions and exiting the cylindrical cavity through tube ports provided in the end caps. A twisted elongated strip is coaxially disposed within the cylindrical cavity extending from the first end to the second end. The twisted elongated strip includes a plurality of radially extending fingers adapted to engage the helical coil to maintain the helical coil in a predetermined position.Type: GrantFiled: June 19, 2009Date of Patent: March 7, 2017Assignee: MAHLE International GmbHInventors: Edward Wolfe, IV, Prasad Shripad Kadle, Carrie M. Kowsky, James Alan Bright

Patent number: 8978745Abstract: An exhaust gas heat recovery (EGHR) heat exchanger, for recovering waste heat from the hot exhaust gases of an internal combustion engine, having a housing and a cylindrical body disposed within the housing. The cylindrical body defines a central passageway and together with the housing defines an annular passageway for the flow of hot exhaust gases. A bypass means is disposed within the central passageway and adapted to selectively by-pass at least a portion of the exhaust gas from the central passageway to the annular passageway. The EGHR heat exchanger also includes at least one fluid tube extending along a tube axis and having at least one lobe extending the length of the tube thereby defining a lobed tube. The lobed tube is twisted about the tube axis forming a twisted lobed tube which is then coiled about the longitudinal axis within the annular exhaust gas passageway.Type: GrantFiled: November 4, 2011Date of Patent: March 17, 2015Assignee: Delphi Technologies, Inc.Inventors: James J. Koo, Mark James Zima, James Alan Bright, James A. Acre

Patent number: 8596080Abstract: An air conditioning system having an improved internal heat exchanger (IHX) assembly. The IHX assembly includes an elongated cavity for low pressure refrigerant flow from an evaporator and an interior tube disposed within the cavity for high pressure refrigerant flow from a condenser, and a pressure equalization passage between the low and high pressure sides. The passage is large enough to allow pressures to equalize between the condenser and evaporator while the air conditioning system is inactive, so as to prevent the pressure differential that would otherwise enable the loss of refrigerant oil from the compressor, and small enough not to effect the operation of the air conditioning system. The pressure equalization passage may be a by-pass valve assembly having a reed portion that is normally open when the air conditioning system is inactive and closed when the air conditioning system is active for maximum cooling efficiency.Type: GrantFiled: May 27, 2010Date of Patent: December 3, 2013Assignee: Delphi Technologies, Inc.Inventors: Edward Wolfe, IV, Prasad Shripad Kadle, James Alan Bright, Mingyu Wang

Patent number: 7770632Abstract: The invention provides for an orientation insensitive heat exchanger assembly for cooling an electronic device comprising a hermetically sealed housing defining a boiling chamber and two condensing chambers. A partition is disposed in the boiling chamber and defines two sets of alternating channels extending in overlapping relationship to one another and with one set of alternating channels open to one of the condensing chambers and the other set of alternating channels open to the other condensing chamber for sealing the condensing chambers from one another. Coolant is maintained in each of the condensing chambers. In operation, if the thermosiphon is tilted with one side lower than the other, the channels open to the lower side are empty of coolant into the lower condensing chamber while the channels open to the opposite upper side hold the coolant over the entire boiling chamber aligning with an electronic device to continue cooling.Type: GrantFiled: September 26, 2007Date of Patent: August 10, 2010Assignee: Coolit Systems, Inc.Inventors: Mohinder Singh Bhatti, Ilya Reyzin, James Alan Bright, Stephen Michael Vetter, Shrikant Mukund Joshi

Patent number: 4076671Abstract: Coating compositions, useful for marking trafficable surfaces such as roads, are disclosed and claimed which comprise a polymer-monomer mixture and a catalyst system. The relative amounts of the components are chosen so as to provide compositions which have, surprisingly, a desirable balance of stability and fast cure.Type: GrantFiled: January 23, 1976Date of Patent: February 28, 1978Assignee: Rohm and Haas CompanyInventor: Alan Bright
