Automotive Engine Colling System

The function of the automotive cooling system is to dissipate part of the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature state.

The cooling system of the engine is divided into air cooling and water cooling. The cooling system that uses air as the cooling medium is called the air cooling system; the cooling system that uses the cooling liquid as the cooling medium is called the water cooling system.

The cooling system of the automotive engine is a forced circulation water cooling system, that is, the water pump is used to increase the pressure of the cooling liquid, and the forced cooling liquid circulates in the engine. The cooling system is mainly composed of a water pump, a radiator, a cooling fan, a compensation water tank, a thermostat, a water jacket in the engine block and the cylinder head, and accessory devices.

In the cooling system, there are actually two cooling cycles: one is the main cycle for cooling the engine, and the other is the heating cycle in the car. Both cycles are centered on the engine and use the same coolant.

In the entire cooling system, the cooling medium is the coolant, and the main components are thermostat, water pump, water pump belt, radiator, cooling fan, water temperature sensor, storage tank, and heating device (similar to radiator).

The role of the cooling system is to ensure that the engine works at the most suitable temperature under all working conditions. Whether the cooling system is matched properly will directly affect the service life and fuel economy of the engine. Therefore, in the design and calculation of the cooling system, The choice of radiator and the matching of fans play a vital role in the cooling system.

In order to facilitate the organization of airflow, the radiator is arranged in front of the vehicle, but due to the limitation of the layout space of the vehicle, an air-conditioning condenser is also arranged in front of it, which will increase the air resistance and affect the air intake of the radiator, thus affecting the cooling system Cooling capacity. The fan is arranged behind the radiator, driven by the fan motor
