  • Publication number: 20230331119
    Abstract: A coolant distribution manifold for a vehicle propulsion battery cooling system is disclosed. The coolant distribution manifold comprises a coolant inlet configured to receive coolant from a temperature conditioning circuit, a receiving section configured to receive coolant from at least two propulsion battery coolant circuits, and a supplying section configured to supply coolant to the at least two coolant circuits. The supplying section is arranged downstream of the coolant inlet and of the receiving section. The present disclosure further relates to a vehicle propulsion battery cooling system, and a vehicle.

  • Patent number: 8250867
    Abstract: An arrangement for recirculation of exhaust gases of a supercharged combustion engine includes a return line for recirculating exhaust gases, an air-cooled EGR cooler and a bypass line having an extent such that it can lead recirculating exhaust gases past the EGR cooler. A valve is operable to be placed in a first position to lead the whole flow of recirculating exhaust gases through the EGR cooler during situations where there is no risk of ice formation in the EGR cooler, and in a second position to lead the whole flow of recirculating exhaust gases through the bypass line during situations where there is risk of ice formation in the EGR cooler.

  • Patent number: 8166758
    Abstract: A cooling arrangement for a vehicle engine including at least one cooling element which has flowing through it a gaseous medium operable to being cooled by an external air flow which flows in a specified direction through the cooling element during operation of the combustion engine. A heat-supplying element is fitted at a location upstream from the cooling element with respect to the direction of the cooling air flow so that at least part of the air flowing through the heat-supplying element also flows through the cooling element. A control device is operable to activate the heat-supplying element so that the air flowing through the heat-supplying element is warmed during situations where there is risk of the gaseous medium in the cooling element being cooled to below a lowest acceptable temperature. The heat-supplying element and the cooling element have a connection so that they constitute a composite unit.

  • Patent number: 8091624
    Abstract: A radiator element in a motor vehicle is disclosed, the motor vehicle including a body, a driver's space with at least one door for access to the driver's space, and a step element with at least one step and situated below the door. An engine cooling system includes a radiator element in which a circulating coolant is cooled by an airflow flowing through the radiator element. The radiator element is positioned close to the step element. An air inlet aperture is positioned between or behind the steps. The radiator element is a second radiator element of the vehicle, operable when the first radiator element cools insufficiently.
