  • Distributed cooling system for a work machine
    Patent number: 10982586
    Abstract: A distributed cooling system is disclosed. The system may include a first radiator to circulate a liquid coolant through the first radiator to cool the liquid coolant, a first fan, electrically connected to the first radiator, to facilitate cooling the liquid coolant, and a first temperature sensor to obtain first temperature data concerning the liquid coolant. The system may include a second radiator to circulate an oil through the second radiator to cool the oil, a second fan, electrically connected to the second radiator, to facilitate cooling the oil, and a second temperature sensor to obtain second temperature data concerning the oil. The system may include a heat exchanger to cool the liquid coolant and the oil and a controller, electrically connected to the first fan, the first temperature sensor, the second fan, and the second temperature sensor, to control the first fan and the second fan.
