A reserve tank device includes a first reserve tank, a second reserve tank, a passage switching member, and a gas-liquid separator. The first reserve tank reserves a cooling water flowing through an engine cooling circuit. The second reserve tank reserves a cooling water flowing through an auxiliary machine cooling circuit. The gas-liquid separator is disposed in the first reserve tank and removes bubbles from the cooling water flowing through the first reserve tank.

Cooling and debris mitigation systems for use with work vehicle powertrains include a pressurized air source, a plurality of impingement outlets positioned proximate the work vehicle powertrain, and a flow network fluidly coupling the pressurized air source to the impingement outlets. A first vortex tube is positioned in the flow network and configured to separate pressurized airflow received from the pressurized air source into a hot stream and a reduced temperature stream. The first vortex tube includes a vortex tube inlet fluidly coupled to the pressurized air source, an exhaust port through which the hot stream is discharged, and a nozzle through which the reduced temperature stream is discharged. The reduced temperature stream impinges upon at least one of the targeted exterior regions of the work vehicle powertrain to provide cooling thereto and reduce debris accumulation thereon.

An air management assembly for a work machine, the air management assembly having a cooling orifice defined in a panel, a cooling fan generating a cooling airflow through the cooling orifice to a cooling package, at least one fixed screen positioned along an intake orifice, and a first baffle positioned at least partially between the cooling orifice and the intake orifice. Wherein, the first baffle directs the cooling airflow partially across the fixed screen to clear the fixed screen of debris.

An air intake screen debris cleaning system may include an intake screen through which air is drawn in a first direction for cooling, a reverse airflow generation system to create a reverse airflow in a second direction opposite the first direction to clear debris from the intake screen, a sensor to sense debris that is collected on the intake screen and a controller to activate the reverse airflow generation system based upon signals from the sensor. In one implementation, the sensor comprises an emitter to emit a sensor beam that extends along a face of the air intake screen and which does not intersect or pass through the air intake screen prior to being sensed.

A cooling device for a power source for a boat propulsion apparatus includes a cooling water passage. The cooling water passage includes a passage provided in the power source, in which an engine or an electric motor is used as the power source of the boat propulsion apparatus that propels a boat. Water from outside the boat is taken into the cooling water passage as cooling water to cool the power source, and the cooling water after cooling the power source is drained from the cooling water passage. From the cooling water flowing through the cooling water passage, foreign substances having a size that clogs the cooling water passage are removed. The cooling water passage is provided with a filter device which can filter residual foreign substances remaining in the cooling water.
