Does the Car Cooling Fan Blow or Suck Air?
1 Answers
For front-mounted engines, the cooling fan blows air towards the engine, while for rear-mounted engines, it blows air towards the radiator. Below are the relevant details: 1. Principle: High-temperature coolant flows from the upper inlet of the radiator to the lower inlet, during which part of the heat carried by the coolant dissipates into the air. As the engine runs longer, the coolant temperature gradually rises, and the radiator's cooling capacity becomes limited, reducing the engine's cooling efficiency. At this point, the fan operates to force cooling, using convective air to accelerate the radiator's heat dissipation. 2. Car Cooling System: The primary function of the cooling system is to dissipate heat into the air to prevent engine overheating, but the cooling system also has other important roles. The engine in a car operates best at an appropriately high temperature.
