Active seal arrangement for use with vehicle condensers
An active seal arrangement operably connected to a radiator and condenser of a vehicle. The arrangement includes at least one movable seal. The seal is selectively movable between a closed, air-restricting position and an open, air-passing position. The seal is slidably attached to a side wall fitted between the radiator and the condenser. A position controller operably connected to at least one sensor regulates the position of the seal.
1. A cooling system for a vehicle comprising:
a heat exchanger assembly including a radiator and a condenser spaced apart from said radiator, whereby a gap is formed between said radiator and said condenser;
opposed side walls extending across the gap between the radiator and condenser;
a slidable seal provided in at least one of the opposed side walls, said slidable seal being selectively slidable between a closed position in which airflow is blocked from entering the gap through the slidable seal and an open position in which airflow passes through the slidable seal and into the gap; and
a seal position controller operatively associated with said slidable seal for moving the slidable seal between the closed and open positions.
2. The cooling system for a vehicle of claim 1 further including a sensor operatively associated with said seal position controller.
3. The cooling system for a vehicle of claim 2 wherein said sensor is a temperature sensor.
4. The cooling system for a vehicle of claim 2 wherein said sensor is selected from the group consisting of an ambient air temperature sensor, a radiator coolant temperature sensor, a condenser fluid temperature sensor, a vehicle speed sensor, an engine RPM sensor, a grade sensor, and a transmission gear selector sensor.
5. An active seal arrangement for use with an engine cooling system having first and second heat exchangers and a gap therebetween, the arrangement comprising:
opposed side walls extending across the gap between the first and second heat exchangers;
a first slidable seal provided in one of the opposed side walls, said first slidable seal being selectively slidable between a closed position in which airflow is blocked from entering the gap through the first slidable seal and an open position in which airflow passes through the first slidable seal and into the gap; and
a second slidable seal provided in another of the opposed side walls, said second slidable seal being selectively slidable between a closed position in which airflow is blocked from entering the gap through the second slidable seal and an open position in which airflow passes through the second slidable seal and into the gap.
6. The active seal arrangement of claim 5 wherein at least one of said first and second slidable seals is a door, said door being slidably positioned on said side wall.
7. The active seal arrangement of claim 5 further including a position controller operatively associated with said first and second slidable seals for moving said first and second slidable seals between the closed and open positions.
8. The active sea arrangement of claim 7 further including a sensor operatively associated with said position controller, said sensor being a temperature sensor.
9. The active sea arrangement of claim 7 further including a sensor associated with said position controller, said sensor being selected from the group consisting of an ambient air temperature sensor, a radiator coolant temperature sensor, a condenser fluid temperature sensor, a vehicle speed sensor, an engine RPM sensor, a grade sensor, and a transmission gear selector sensor.
10. An active seal arrangement for use with an engine cooling system having first and second heat exchangers and a gap therebetween, the arrangement comprising:
opposed side walls extending across the gap between the first and second heat exchangers;
a slidable seal provided in at least one of the side walls, said slidable seal being selectively slidable between a closed position in which airflow is blocked from entering the gap through the slidable seal and an open position in which airflow passes through the slidable seal and into the gap;
a seal position controller operatively associated with said slidable seal for moving the slidable seal between the closed and open positions; and
a temperature sensor operatively associated with said controller.
11. The active seal arrangement of claim 10 wherein said temperature sensor is selected from the group consisting of an air temperature sensor and a fluid temperature sensor.
