Do you know the cooling system of cars?

The function of the car cooling system is to keep the car in an appropriate temperature range under all operating conditions.


The cooling system of a car is divided into air cooling and water cooling. The air-cooled system is called the air-cooled system with air as the cooling medium, and the water-cooled system is called the water-cooled system with the coolant as the cooling medium. Usually the water cooling system consists of water pump, radiator, cooling fan, thermostat, compensation bucket, water jacket in the engine block and cylinder head, and other auxiliary devices. Among them, the radiator is responsible for the cooling of circulating water. Its water pipes and radiating fins are mostly made of aluminum. The aluminum water pipes are made of flat shape, and the radiating fins are corrugated. Pay attention to the heat dissipation performance. The installation direction is perpendicular to the direction of air flow. The wind resistance should be small and the cooling efficiency should be high.


 Coolant flows in the radiator core, and air passes outside the radiator core. The hot coolant becomes cold by dissipating heat to the air, and the cold air heats up by absorbing the heat from the coolant, so the radiator is a heat exchanger.
