Research Of Heat Exchange Technology Of The Whole Bearing Radiator For AC Drive E-loco

Traction transformer and traction converter are the key components of AC drive electric locomotive and wirings in them will bring heat dissipation during operating.Danger such as ageing of insulation and firing will appear in wirings if the temperature of wirings rises beyond what it can bear.Suit cooling system must be adopted to take the heat away during traction transformation and traction converter operating,so that traction transformer and traction converter could work normally and the train could operate safely.Traction transformer and traction converter are the key parts of cooling system.Flowing the development of AC drive electric locomotive and cooling technology of traction transformer and traction converter develops forward also,It appears more kinds of cooler structures and the whole bearing radiator is a new type of traction transformer and traction converter.We accumulate a lot of basic data of design and test during research of radiator structure,heat transfer analyzation,design technology,process and test research for the whole bearing radiator,especially the research of heat transfer ability, fluid pressure loss characteristic,press Feasibility and products reliability(including Simulated long life test at increased random vibration levels,pulse pressure test, release pressure etc.) and all the research will given a great push for radiator developing.we master the heat transfer technology principle of the whole bearing radiator and current design method of this kind of radiator.The whole bearing radiator technology will lead cooling technology of local e-loco to international top-grade level and raise the technology level of local locomotive key parts.
