  • Patent number: 9327592
    Abstract: A vehicle includes a body that extends along a longitudinal axis, between a forward end and a rearward end. A front bumper assembly is disposed at the forward end of the body. The front bumper assembly includes a B-shaped structure that defines a channel that extends transversely across the body, relative to the longitudinal axis. A heat exchanger is disposed within the channel of the bumper structure. The heat exchanger is operable to transfer heat from a fluid circulating through the heat exchanger to a flow of air passing across the heat exchanger. The fluid may include, but is not limited to, engine oil, transmission fluid, power steering fluid, or an engine coolant from a low temperature coolant loop.

  • Patent number: 8966917
    Abstract: A coolant reservoir includes a body portion defining an interior cavity configured to hold a coolant; and a barrier wall positioned within the body portion to partition the interior cavity into an upper chamber and a lower chamber, the barrier wall defining an opening therethrough that allows fluid communication between the lower chamber and the upper chamber.

  • Patent number: 8448460
    Abstract: A chiller bypass system is provided for deployment onboard a vehicle that includes a battery pack through which a first coolant is circulated. In one embodiment, the chiller bypass system comprises a chiller, a chiller bypass duct fluidly coupled to the battery pack and configured to supply the first coolant thereto, and a chiller bypass valve. The chiller bypass valve includes: (i) a valve inlet fluidly coupled to the battery pack and configured to receive the first coolant therefrom, (ii) a first valve outlet fluidly coupled to the chiller and configured to supply the first coolant thereto, and (iii) a second valve outlet fluidly coupled to the chiller bypass duct and configured to supply the first coolant thereto. The chiller bypass valve selectively directs coolant flow between the first valve outlet and the second valve outlet to adjust the volume of the first coolant cooled by the chiller.

  • Patent number: 8029343
    Abstract: A battery pack cooling and body pressure relief system for a vehicle having a passenger cabin is disclosed. The system may include an intake air flow duct connected between the passenger cabin and the battery pack, and an air flow duct connected between the exhaust air outlet and the body pressure relief valve. The system may include a one-way cabin pressure relief vent connected to the air flow duct and configured to selectively allow for air flow into the air flow duct, and may include a duct pressure relief vent connected to the air flow duct and configured to selectively allow for air flow out of the air flow duct into the vehicle.

  • Patent number: 7275379
    Abstract: The present invention concerns a method for controlling the operation of an automotive HVAC system. The HVAC system includes at least a refrigerant compressor and a refrigerant evaporator. The method includes the steps of calculating an ambient air enthalpy value; comparing the calculated ambient air enthalpy value to at least one predetermined enthalpy value; and selectively changing the operation of the refrigerant compressor based on the comparison.
