Abstract: A cooling control system is provided for a mobile machine having an engine. The cooling control system may have a circuit fluidly connected to the engine, and a heat exchanger configured to dissipate heat from coolant in the circuit. The cooling control system may also have a fan disposed proximate the heat exchanger, a thermostat configured to selectively allow coolant through the heat exchanger, and a locating device configured to generate a location signal indicative of a location of the mobile machine. The cooling control system may further have a pressure sensor configured to generate a pressure signal indicative of a barometric pressure in proximity to the mobile machine, and a controller in communication with the fan, the thermostat, the locating device, and the pressure sensor.

Abstract: A roof structure for a power module of a locomotive is disclosed. The roof structure may have an upper roof layer and at least a portion of the upper roof layer may have a first set of cooling passages. The roof structure may further have a lower roof layer at least partially positioned below the upper roof layer and at least a portion of the lower roof layer may have a second set of cooling passages. Each of the cooling passages of the first set of cooling passages may not overlap a cooling passage of second set of cooling passages.
