Water-cooled engine cooling circuit is an important component, can absorb the heat of the cylinder to prevent engine overheating due to the specific heat capacity of water is large, absorb the heat of the cylinder after the temperature rise is not a lot, so the engine's heat through the cooling water of this liquid circuit, the use of water as a heat carrier heat conduction, and then through a large area of the heat sink to the convection of the way to dissipate heat, in order to maintain the engine's appropriate working temperature.Water-cooled engine cooling circuit is an important component, can absorb the heat of the cylinder to prevent engine overheating due to the specific heat capacity of water is large, absorb the heat of the cylinder after the temperature rise is not a lot, so the engine's heat through the cooling water of this liquid circuit, the use of water as a heat carrier heat conduction, and then through a large area of the heat sink to the convection of the way to dissipate heat, in order to maintain the engine's appropriate working temperature.

The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal operating range. On high-power reinforced engines, an oil cooler must be installed due to the high thermal load. When the engine is running, the viscosity of the oil becomes thinner as the temperature rises, which reduces the lubricating ability. Therefore, some engines are equipped with an oil cooler, the role of which is to reduce the oil temperature, to maintain a certain viscosity of the lubricant.The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal operating range.

The principle of the intercooler is to cool the air entering the cylinder between the turbocharger outlet and the intake pipe. The intercooler is like a radiator, air-cooled or water-cooled, and the heat of the air escapes into the atmosphere through cooling.

The role of the condenser is to compressor discharge of high-temperature, high-pressure refrigerant vapor cooling, so that it condenses into liquid high-pressure refrigerant.The role of the condenser is to compressor discharge of high-temperature, high-pressure refrigerant vapor cooling, so that it condenses into liquid high-pressure refrigerant.

The main function of an automotive evaporator is to cool the air inside the vehicle by utilizing the principle of heat absorption by refrigerant evaporation. The low-pressure, low-temperature liquid refrigerant enters the evaporator and exchanges heat with the fan-driven airflow at the ambient temperature of the vehicle.
