Simulation And Analysis Of Locomotive Electronic Components Ventilation Cooling System

The progress of science and technology make the internal structure of locomotive is more and more complex,the locomotive electronic components also increase gradually,which resulted in increased heat dissipation is,how to reasonable heat dissipation has become a key problem.Nowadays CFD technology is increasingly mature,make it become the main approach for the analysis of electronic components and ventilation cooling system,it can reduce the test time,compared with the traditional design method,greatly improving the efficiency.Based on the locomotive electrical components ventilation cooling system as the research object.First in a three dimensional software Creo entity modeling and analysis of construction ventilation system in its internal structure and main characteristics,then the electrical components ventilation system was established based on ANSYS FLUENT software calculation model of the whole flow field,and generate the Unstructured grid.Through to the electrical cabinet internal flow field numerical simulation calculation,calculate the electrical components ventilation cooling system in the gas flow characteristics,the main analysis system including the temperature of the air duct distribution,temperature distribution in the various electrical components and relative radiator temperature distribution.By the calculation analysis,through constantly adjust the structure of the fin optimization scheme,in the case of meet the cooling requirements as far as possible to save material.The optimization design of this item makes relevant personnel can make use of computer simulation technology,combined with the mathematical model,carries on the air duct design,reduce test cost,shorten the development cycle,reducing the cost of production.
