What are the components and functions of the cooling system?

The cooling system consists of a water pump, radiator, cooling fan, thermostat, expansion tank, etc. The function of the cooling system is to keep the engine within an appropriate temperature range under all operating conditions. The cooling system must prevent the engine from overheating as well as from becoming too cold in winter. Detailed introduction to the components of the cooling system: Water pump: Pressurizes the coolant to ensure its circulation within the cooling system. Centrifugal water pumps are widely used in automotive engines. Radiator: Composed of three parts: the inlet tank, outlet tank, and radiator core. Coolant flows inside the radiator core while air passes outside it. The hot coolant cools down by dissipating heat to the air, while the cold air warms up by absorbing the heat from the coolant, making the radiator a heat exchanger. Cooling fan: Draws in air when rotating, directing it through the radiator to enhance its cooling capacity and accelerate the cooling of the coolant. Thermostat: A valve that controls the flow path of the coolant. It opens or closes the passage to the radiator based on the temperature of the coolant. Expansion tank: When the coolant expands due to heat, part of it flows into the expansion tank; when the coolant cools down, part of it is drawn back into the radiator, preventing coolant loss.
