The truck radiator is a very important part of the cooling system. It relies on the heat exchange between two fluids to work, one is coolant and the other is air. The heat dissipation capacity of the radiator cannot be too high or too low. Too high will cause the engine temperature to be too low, resulting in insufficient combustion and poor cooling and lubrication. If it is too low, it will cause the engine to overheat and reduce the strength and rigidity of the parts.
When designing a truck radiator, the first consideration is the heat dissipation capacity and layout space of the radiator, and then we also need to consider the heat dissipation coefficient and weight of the radiator, because we already have requirements for heat dissipation and wind resistance, and water resistance when matching the cooling system, the core structure of the radiator is basically determined. Of course, we hope that the radiator has low wind resistance, high heat dissipation coefficient, and achieves a lightweight and low-cost design.
The main factors that affect the wind resistance are the flat tube spacing of the car radiator, the wave distance of the heat dissipation band, and the window opening angle. At the same time, we must ensure the flatness of the radiator core to ensure good natural convection.
In order to obtain a high heat dissipation coefficient, we have to increase the thermal resistance of the air model as much as possible, because the reciprocal of the thermal resistance sum is the heat dissipation coefficient, and the thermal resistance of the air model accounts for about 80.1% of the thermal resistance of the cooling system. The second is that the heat sink material accounts for about 8.9% of the system's thermal resistance. We need to develop materials with lower thermal resistance. The remaining thermal resistance is pipeline thermal resistance and tube wall thermal resistance. At present, in order to consider costs, aluminum radiators are basically used.
