Abstract
A temperature control system includes an enclosure having a plurality of adjoining walls. At least one inlet is disposed within at least one of the walls. The at least one inlet has an electrically controlled inlet fan associated with it. A plurality of outlet louver assemblies are disposed within at least an other wall and include a plurality of moveable louvers. An actuator is coupled with each outlet louver assembly to move the plurality of moveable louvers. An ambient air sensor is disposed within the enclosure for sensing the ambient temperature within the enclosure and providing an output signal which is conducted to an electrical processing circuit. Alternatively, the ambient air sensor may be located without the enclosure. Temperature sensors are also coupled with the engine, charge air and transmission cooler for sensing their respective temperatures and providing output signals which are conducted to the electrical processing circuit. The electrical processing circuit is coupled with the actuators and inlet fans and controls the movement of the plurality of louvers and inlet fans dependent upon the output signals from the temperatures sensors.
