Abstract:
1. A cooling system for an engine, the cooling system comprising: a coolant tank configured to hold a fluid coolant and coupled with a tank conduit through which the coolant flows into the coolant tank; a heat exchanger fluidly coupled with a supply conduit through which the coolant flows at least one of into or out of the heat exchanger, the heat exchanger also fluidly coupled with a radiator conduit through which the coolant flows out of the heat exchanger to the coolant tank, the heat exchanger disposed above the coolant tank in a rail vehicle that includes the engine, along a top side of the rail vehicle, and between opposite lateral exterior walls of the rail vehicle, the heat exchanger exposed to ambient air along the top side of the rail vehicle; and a drain valve fluidly coupled with the coolant tank by the tank conduit and with the heat exchanger by the supply conduit, the drain valve disposed above the coolant tank and beneath the heat exchanger in the rail vehicle, the drain valve accessible through a window in at least one of the lateral exterior walls of the rail vehicle and above a walkway extending outside of and along the at least one of the lateral exterior walls so that a human operator can access the drain valve through the window in the at least one of the lateral exterior walls while the human operator stands on the walkway, the drain valve fluidly coupled with a drain conduit that directs the coolant out of the cooling system, the drain valve configured to alternate between a closed position and an open position, wherein the fluid flows from the heat exchanger to the coolant tank through the radiator conduit and from the heat exchanger to the coolant tank via the supply conduit, the drain valve, and the tank conduit when the drain valve is in the closed position, and wherein the fluid flows from the heat exchanger and out of the cooling system through the supply conduit, the drain valve, and the drain conduit when the drain valve is in the open position, further wherein the drain valve prevents the fluid from flowing from the heat exchanger to the coolant tank via the supply conduit, the drain valve, and the tank conduit when the drain valve is in the open position.
