Experimental Study Of Radiator Module In Vehicle

Radiator module is an essential part of the engine cooling system. The cooling effect of the engine and vehicle is, in a large part, decided by the performance of the radiator module. Along with the development of vehicle and engine technology, the requirements on the radiator module have become increasingly high. As domestic researches mainly focus on single radiator, and lack of radiator module study, a radiator module consisted by an intercooler and a water radiator was chosen to be the study object, on which some experiments were carried out.In order to get the data while the radiator module is working in engine room with the vehicle running on the road, a measurement system for on road test based on the software developed on the platform of C++Builder was developed. The system construction was also researched, and some suggestions on sensor selection and optimization of data collection system were given.An on road test was carried out, which was followed by the analysis of the working performance of the radiator module while the vehicle was in different gears and the engine was at different speed. The suggestions for the optimization of the experiment method were also given.The radiator module was then mounted in a wind tunnel, and the data collected in on road test was used here to set the initial state. The wind tunnel test results verified that the radiator module basically met the cooling requirements of the engine. The Impact of wind velocity, flow of hot air in intercooler and flow of hot water in water radiator on the cooling performance of the radiator module was also analyzed. Then some recommendations on the optimization of the radiator module were given.
