Research on matching of engine cooling system of a certain type of tractor

The performance of the cooling system is crucial to ensure that the engine runs stably at a suitable temperature, and improves the service life and fuel economy of the engine. In this study, based on the actual parameters of the tractor engine, the theoretical calculation of the cooling system is carried out, and the heat dissipation, ventilation and water flow are determined; Then, based on this, the parameters of each module of the cooling system are selected to determine the matching scheme of the cooling system; Finally, the performance of the cooling system is verified. The test results show that the matching design of the cooling system can meet the cooling requirements of the engine, and can provide a reference for the matching design of the same type of cooling system.
