technical field

Usually trucks use a turbocharged engine, the temperature of the air will increase significantly after entering the turbocharger, and the intercooler just plays the role of cooling the air, the high temperature air is cooled by the intercooler, and then enters the engine. The system layout of the car is greatly affected by the space. Generally, the cooling system arranges the radiator at the rear of the intercooler, and the distance is very close. When natural wind blows into the engine compartment from the front, it first passes through the intercooler and then through the radiator. The air passing through the intercooler is heated and the temperature rises. The coolant on the upper part of the radiator has just come out of the engine, and the uncooled temperature is very high. It needs the wind with a lower temperature to cool it. At this time, the natural wind has been heated by the intercooler and its temperature has risen, which greatly affects the heat dissipation performance.

In the radiator 4, the engine water cools the pressurized air, causing the temperature of the engine water to rise. Under the same conditions, the increased heat dissipation will cause the radiator 4 to increase, which is not conducive to the layout of the vehicle.
