Abstract: An enclosure for a generator includes an air inlet formed at a first end of the enclosure, and an air inlet opening formed in a sidewall of the enclosure. The air inlet includes an air inlet duct formed in an interior space of the enclosure, and in fluid communication with the air inlet opening. The air inlet duct receives the airflow from the air inlet opening to direct the airflow towards an air outlet of the enclosure. The air outlet includes an air outlet duct formed at a second end of the enclosure which receives the airflow from the air inlet opening. The air outlet duct directs the airflow towards an air outlet opening formed in a top plate of the enclosure which provides an exit for the airflow to escape from the interior space to an ambient environment of the enclosure.

Abstract: An insulated reductant tank that is arranged so that it has an insulated upper portion and a tapered lower portion, the reductant tank configured to allow frozen reductant to move into the insulated upper portion and reduce the damage that frozen reductant can cause to a reductant tank when the frozen reductant expands. The insulated reductant tank can include at least one header configured to draw reductant from the reductant tank and supply the reductant to an exhaust aftertreatment system, an insulation layer lining an upper portion of the reductant tank, a tapered lower portion, and at least one baffle configured to control a flow of reductant.

Abstract: An energy storage device cooling system includes a housing, at least one energy storage device within the housing, and a coolant circuit including a first flow portion extending through the housing, the coolant circuit configured to supply coolant for heat exchange with the at least one energy storage device. The energy storage device cooling system also includes a chiller system including: a coolant supply, a heat exchanger, and an outlet in fluid communication with the first flow portion. The energy storage device cooling system also includes a controller configured to alter a function of the chiller system when a sensed temperature does not exceed a first temperature threshold.

Abstract: In one aspect, a thermal management system includes a first coolant circuit, through which a first coolant circulates, and including at least a radiator for cooling the first coolant, a storage containing one or more power electronics, a heat exchanger, and a thermostatic valve that outputs the first coolant to at least one of the storage containing the one or more power electronics and the heat exchanger. A second coolant circuit, through which a second coolant circulates, includes the heat exchanger configured to cool the second coolant using the first coolant, an energy storage unit cooled by the second coolant, and a refrigeration unit configured to cool the second coolant. A coolant temperature sensor outputs a temperature of the coolant in the second coolant circuit, and a controller controls at least the refrigeration unit based on the temperature of the coolant output by the coolant temperature sensor.

Abstract: A system for obtaining purified water includes a heat exchanger fluidly coupled to the heat source for receiving a thermal management fluid from the heat source, and a reservoir fluidly coupled with the heat exchanger to supply water, at an ambient temperature, for receiving heat from the thermal management fluid at the heat exchanger. A pump provides a pre-defined flow rate of the water from the reservoir to the heat exchanger based on a temperature gradient of the thermal management fluid across the heat exchanger. A purification device has a cold side chamber in fluid communication with the pump and the heat exchanger while a hot side chamber is in fluid communication with the heat exchanger and the reservoir. The cold and hot side chambers of the purification device thermally co-operate with each other to develop condensate therebetween from moisture present in the ambient air for forming water.
