Abstract:
1. A cooling system for a heat producing system in a vehicle, comprising: a heat exchanger in fluid communication with the heat producing system and configured to receive a temperature control fluid therethrough; a first fan operable in a first rotational direction to move air through the heat exchanger in a first direction; a second fan disposed radially adjacent the first fan, the second fan being operable in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in the first direction; and a control system for controlling operation of the fans and including at least one controller and a temperature sensor, the controller being configured to: shut off when the vehicle is operating and the temperature of the al least one controller is greater than a first predetermined controller temperature, operate for a predetermined period of time after the vehicle is started, independently of the temperature of the at least one controller, and shut off after the predetermined period of time has elapsed and the temperature of the at least one controller is greater than the first predetermined controller temperature.
