What is the radiator on a diesel generator? What is it for?
The radiator on a diesel generator is the part that removes the heat from the engine coolant and helps to keep the engine from overheating.
How does it work?
The radiator has fins and pipes. The engine coolant is pumped though the pipes by the engines coolant pump. This coolant is hot, having come from the engine and as it passes through the radiator pipes, the heat transfers to the fins.
The radiator will have a fan, either electric or driven from the engines crank shaft by a series of pulleys and belts, which blows cool ambient air through the radiator fins. The heat at the fins is transferred to the cool air heating it up. this process takes the heat away from the engine.
