Background
The intercooler is usually installed and used together with a supercharger, is a turbocharging accessory, and has the functions of reducing the temperature of the supercharged high-temperature air so as to reduce the heat load of the engine, improve the air inflow and further increase the power of the engine. For supercharged engines, the charge air cooler is an important component of the supercharging system. In either a supercharged engine or a turbocharged engine, an intercooler is required to be installed between the supercharger and the intake manifold.
One reason why turbocharged engines have more power than conventional engines is that they can be ventilated more efficiently than the natural air intake of a typical engine. After air enters the turbo-charger, the temperature of the air can be greatly increased, the density of the air is correspondingly reduced, the intercooler plays a role in cooling the air, and high-temperature air is cooled by the intercooler and then enters the engine. If the high-temperature air after pressurization directly enters the engine due to lack of an intercooler, the phenomenon that the engine knocks or even is damaged and stalls due to overhigh air temperature can be caused.
The cooling mode of the intercooler is classified, and the cooling mode can be divided into air cooling and water cooling. The air-cooled intercooler is installed near a radiator of an engine and directly cools air in the intercooler by means of air flow during vehicle running. A water-cooled intercooler is installed adjacent the intake manifold and cools by cooling heat rejection from the coolant in the engine cooling system.
