Numerical Simulation And Research On Hydraulic Oil Cooler Of GMC16A Type Rail Grinding Train

Now with the continuous development of technology in the field of railway engineeringmachine, the use of the high power engine mounting, also increasing more and more the heat,in order to make the normal work of the engineering machinery, it must require heatdissipation by the cooling system. Therefore, people pay more and more attention to thestudy of engineering machinery of heat balance.The radiator is an important part in thecooling system, the rationality of structure and heat transfer efficiency is the pursuit ofcommon goals in recent years.Aluminum plate fin type radiator is a kind of economic efficiency, the quality of light,durable, strong practicability, which has been widely applied in railway engineeringmachinery in our country. In this article analysis the type GMC16A rail grinding train sourcesand hydraulic oil cooler GMC16A type rail grinding the cooling unit of the train, thehydraulic oil use the double process of aluminum fin type radiator, which can be cooldown by a motor drive the fan.Firstly this article summarizes the development and application of fin type radiatorconditions, introducing the fin type radiator heat transfer theory and numerical heat transfercalculation method, stating detailediy the theory of the heat transfer performance of theanalysis process, and discussing the numerical calculation method in brief, at the same timeillustrating the design process and the methods of the hydraulic oil cooler, establishingGMC16A type rail grinding train overall Two-dimensional model of the hydraulic oil coolerand fin channel3D model, then using computational fluid dynamics (CFD) software Fluenton the fluid flow and heat transfer properties are analyzed in numerical simulation,discussing the radiator on the air side inlet velocity changes cause by unit of the change ofthe flow field and temperature field, different waveform of finned air side flow field changesare compared, in order to verify the rationality of the structure of the radiator, for moreeffective radiator numerical simulation calculation method is discussed, in order to furthercarry out the thermal balance of the cooling unit work provides theory basis.
