Abstract: A heat exchanger tube for an automobile cooling system comprising a first end, a second end and a wall formed from a unitary sheet of formable material. The wall has an outer surface and an inner surface and includes a first side and a second side spaced apart and parallel to one another extending longitudinally between the first end and the second end, a first distal end, a second distal end, a first edge, a second edge, a first partition, a second partition and a compound partition extending between the first and second sides longitudinally between the first and second ends and defining four fluid channels extending longitudinally between the first and second ends.

Abstract: An air-to-air charge air cooler for cooling air supplied to an internal combustion engine includes a tube assembly including a plurality of tubes extending in a longitudinal direction. The plurality of tubes is arranged adjacent to one another. Each of the plurality of tubes includes an inlet to receive airflow and an outlet to output airflow. A turbulator is arranged in at least one of the plurality of tubes, the turbulator having a pitch defined in a direction transverse to airflow through the tube. The pitch varies in at least one of a longitudinal direction and a transverse direction of the tube.

Abstract: A method for internal transmission oil cooler (ITOC) mounting includes molding an ITOC end tank to include at least one aperture extending through an external fluid port for connecting a transmission fluid line. At least one ITOC mounting fixture is disposed internal to the ITOC end tank, and an ITOC having at least one fluid aperture surrounded by an O-ring is aligned with the at least one mounting fixture. The ITOC is snapped into the at least one mounting fixture to create a press fit fluid seal between the O-ring and the at least one aperture of the end tank.

Abstract: System and methods are disclosed incorporating a battery cooling system design that may provide for relatively uniform cooling of an associated battery system. In certain embodiments, a battery cooling system may include a central coolant delivery system configured to circulate liquid coolant through one or more coolant flow channels included in one or more cooling plates. One or more seals may be used to couple the central coolant delivery system to the one or more coolant delivery plates. Embodiments of the disclosed battery cooling system may allow for relatively straightforward manufacturing processes and/or assembly of the cooling system, provide sufficient mechanical strength to support a group of battery packs, reduce the occurrence of liquid coolant leaks, and/or provide for relatively uniform cooling of a group of battery packs.

Abstract: A fan assembly includes a first fan and a second fan spaced from the first fan. The first fan includes a first central portion and a plurality of first fan blades being supported by the first central portion. The second fan includes a second central portion and a plurality of second fan blades being supported by the second central portion. The fan assembly also includes a single drive unit configured to selectively operate both of the first and second fans. The single drive unit is spaced from at least one of the first and second fans to indirectly operate at least one of the fans.

Abstract: Vehicular radiators and other heat exchangers containing carbon nanotubes (CNTs) are provided, as are methods for manufacturing nanotube heat exchangers. In one embodiment, the nanotube heat exchanger includes a coolant flow passage, an airflow path, a heat exchanger core bounding at least a portion of the coolant flow passage and the airflow path. The heat exchanger core contains a plurality of CNTs configured to enhance heat transfer from a coolant conducted through the coolant flow passage to airflow directed along the airflow path during operation of the nanotube heat exchanger. The CNTs can be, for example, single walled CNTs or other CNTs incorporated into one or more regions of the heat exchanger core by applying a nanotube coating to selected surfaces of the heat exchanger core or by producing the heat exchanger core to include one or more sintered, CNT-containing components.

Abstract: A fuel system is provided for supplying fuel to a fuel injector associated with a cylinder head, wherein the fuel injector has an opening and the cylinder head has a bore. The fuel system includes a fuel pipe disposable in the bore of the cylinder head and including a pipe body having first and second ends. The first end is engageable with the fuel injector and alignable with the opening. The fuel system further includes a fuel line assembly including a fuel line having an end that is engageable with the second end of the pipe body. The assembly further includes a rotatable nut engageable with the fuel line and threadingly engageable with the cylinder head for urging the end of the fuel line into engagement with the second end of the pipe body to thereby urge the first end of the pipe body into engagement with the fuel injector.
