Abstract
A vehicle heat exchanger arrangement is provided basically with a heat exchanger, a pusher fan and a power recovery device. The heat exchanger has a first side and a second side. The pusher fan is disposed on the first side of the heat exchanger to push air through the heat exchanger to the second side. The power recovery device is disposed on the second side of the heat exchanger to receive the air pushed through the heat exchanger by the pusher fan such that the power recovery device generates electricity.
Claims19
A vehicle heat exchanger arrangement comprising:
- a shroud having an inlet, an outlet and a bypass outlet;
- a heat exchanger disposed within the shroud having a first side facing the inlet and a second side facing the outlet and the bypass outlet;
- a pusher fan disposed at the inlet of the shroud to push air through the heat exchanger to the outlet;
- a power recovery device disposed at the outlet of the shroud to receive the air pushed through the heat exchanger by the pusher fan such that the power recovery device generates electricity;
- a bypass member disposed over the bypass outlet and configured to move between a closed position covering the bypass outlet and an open position, the bypass member being arranged to selectively discharge the air pushed through the heat exchanger by the pusher fan out of the bypass opening;
- and
- a controller configured to automatically operate the bypass member in response to cooling demand conditions.
4 more elements
A vehicle heat exchanger arrangement comprising:
- a heat exchanger having a first side and a second side;
- an electrically powered pusher fan disposed on the first side of the heat exchanger to push air through the heat exchanger to the second side;
- a generator fan disposed on the second side of the heat exchanger to receive the air pushed through the heat exchanger by the pusher fan such that the generator fan generates electricity in response to the air rotating blades of the generator fan, the generator fan being electrically connected to the pusher fan to supply electrical power generated by the generator fan to the pusher fan.
