Description
Technical Field
The invention relates to the field of automobiles, in particular to a radiator.
Background
The design and development of the radiator for radiating the water air cooler and the EGR by the six engines in the state of commercial vehicles are realized. The requirement of the gas commercial vehicle on a cooling system is increased by about 15 percent compared with the fuel vehicle, meanwhile, the self weight of the whole vehicle is reduced as much as possible for saving energy, and a narrow body frame and a narrow body vehicle body are very feasible measures. But this also presents new challenges to the cooling system. Meanwhile, the emission reaches the standard, and EGR is an effective means for meeting the emission requirement of the engine. In order to meet the overall performance requirement, a cooling module of a double-radiator water-adding air intercooler is newly developed.
In the process of radiating the water air cooler and the EGR. The flow of the cooling liquid for the water-air intercooler and the EGR heat dissipation is low, and the liquid-gas temperature difference is low. The cooling liquid is driven by a water diversion pump of the engine to circulate. And the EGR and the water air coolers are smaller, and the diameters of the inlet medium and outlet pipes of the EGR and water air coolers are also smaller, so that the water flow is also smaller, and is generally 40-60L/min. Meanwhile, the intercooler has requirements on the temperature rise of the inlet air, and the temperature rise of the inlet air is within 25-30 degrees, so that the cooling temperature of the intercooler used as a radiator for cooling the intercooler is lower than the temperature. However, the heat dissipation capacity of the radiator must meet the requirement of simultaneously taking away the heat of the water air intercooler and the EGR, and the existing radiator cannot meet the working environment with low flow, low liquid cooler temperature difference and high heat dissipation capacity.
