Abstract: A thermal management system for an exothermic process includes cooling units, each including a hot coolant port through which coolant heated by the exothermic process flows and a cold coolant port through which the coolant that has been heat reduced by the cooling units flows. A pair of mounting rails have respective interior chambers that are in fluid communication with corresponding coolant ports formed on the respective mounting rails. Conduits interconnect the coolant port of one of the mounting rails to the hot coolant port of each of the cooling units and the coolant port of the other one of the mounting rails to the cold coolant port of each of the cooling units.

Abstract: Integrated fuel cell cooling systems and methods can comprise or implement a first coolant circuit to process a first coolant; a second coolant circuit to process a second coolant, the second coolant being a dielectric fluid; a liquid-liquid heat exchanger operatively coupled to the first coolant circuit and the second coolant circuit; and a proton exchange membrane (PEM) fuel cell. The first coolant circuit and the second coolant circuit can be fluidly separated from each other.

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.
