Patent number: 6745829Abstract: This invention provides an auxiliary heating and cooling circuit for an automobile interior compartment. The auxiliary circuit uses a circulated liquid heat transfer fluid such as the same liquid used for the vehicle engine system. In a cooling mode, the liquid is circulated through a heat exchanger within the vehicles air-conditioning circuit. The cooled fluid flows to an auxiliary heat exchanger where cooled air is made available. In a heating mode, the auxiliary system is connected directly with the engines cooling system where the hot engine coolant flows through the auxiliary heat exchanger for interior compartment heating.Type: GrantFiled: November 29, 2001Date of Patent: June 8, 2004Assignee: Visteon Global Technologies, Inc.Inventors: Henry Mehraban, John J. Meyer

Patent number: 6523365Abstract: An accumulator with an internal heat exchanger for use in an air conditioning or refrigeration system having a compressor, a condenser, an expansion device, and an evaporator is disclosed. In operation, the accumulator is placed in the system so high pressure, high temperature refrigerant flowing from the condenser and low pressure, low temperature refrigerant flowing from the evaporator simultaneously enter and flow through the heat exchanger disposed in the accumulator whereby the low pressure, low temperature refrigerant absorbs heat and thereby cools the high pressure, high temperature refrigerant. In one embodiment, the heat exchanger comprises a tube having at least one high temperature channel and one low temperature channel extending through the interior of the tube. In a second embodiment, the heat exchanger comprises a single spirally wound coaxial tube having an outer tube and an inner tube positioned within the outer tube.Type: GrantFiled: December 29, 2000Date of Patent: February 25, 2003Assignee: Visteon Global Technologies, Inc.Inventors: Chao A. Zhang, Henry Mehraban, Richard G. Gibbons, Jr., Teodor Urdea

Patent number: 6401809Abstract: A continuous combination fin for a heat exchanger includes a base wall having a first portion, a second portion and a third portion. The continuous combination fin also includes a plurality of entrance louvers in the first portion extending outwardly at a predetermined angle in a first direction from the base wall. The continuous combination fin includes a plurality of exit louvers in the third portion extending outwardly at a predetermined angle in a second direction from the base wall reversed from the first direction. The continuous combination fin further includes a plurality of drainage louvers in one of the first portion and the second portion and the third portion that are off-set relative to each other such that air flows through the entrance louvers and exit louvers and water drains through the drainage louvers.Type: GrantFiled: December 10, 1999Date of Patent: June 11, 2002Assignee: Visteon Global Technologies, Inc.Inventors: Chao Abraham Zhang, Shyr-Ing Hu, Henry Mehraban, Ramez S.
