Abstract:
This work aims to demonstrate a cooling package selection for an agricultural machine equipped with Diesel engine considering different radiators area / material and fan blade angles, pursuing the best match of performance, cost and weight.It was investigated two types of radiators made from copper-brass and aluminum, two types of charge air cooler varying the dimensions and four types of fans varying the blade angle.The selection method chosen was the experimental testing. The tests were performed according to the standard SAE and internal procedures at MWM Motores Diesel laboratories located at São Paulo / Brazil.When compared with cooper-brass, the aluminum radiator presents worse heat exchange performance what makes its size increase in order to compensate the gap. Even with bigger size, the aluminum radiator keeps lighter and cheaper.The fan with bigger angle blade can deliver more airflow helping the overall cooling package performance but in other hand, some specific issues should be taken care such as the increase of fan noise.
