Pilot Study Of The Temperature Field Simulation Of Evaporative Cooling Electromagnetic Separator And Composite-type Evaporative Cooling Media

The temperature field in RCDZ type electromagnetic iron-separator wassimulated by finite element method in this paper. Based on a 4 kVAsingle-phase evaporative cooling transformer model, the experimentalresearches were performed with three combining ways of coolants, such aspure evaporative cooling material, evaporative cooling material combiningwith solid filling blocks (Hereinafter as "solid filling") and evaporativecooling material mixing with other liquid materials (Hereinafter as "liquidmixing").In chapter 2, a two-dimensional temperature field situation model of theRCDZ type electromagnetic iron-separator is set up, and the temperaturedistribution is analyzed. A comparison study between the experimental dataand computational ones verifies the validity of the temperature fieldsimulation method.The coolant used in the evaporative cooling electromagnetic iron-separatorand the evaporative cooling power transformer model is very expensive, inchapter 3 , 4 and 5, the temperature distribution experiments for pureevaporative cooling material, solid filling and liquid mixing coolants wereimplemented and described detailedly. The experimental results show therelationship among current density, cooling water velocity, the temperaturedistribution and coolants mixing proportion. In chapter 5, the cost reducingeffects are analyzed by comparing the various coolant mixing schemesdescribed above.The temperature distributions of RCDZ type electromagnetic iron-separatorhave been known in this paper. Above research results provide a primary basisand reference for further structural improvements and experimental research.At the same time, the experimental research results of the 4 kVA single-phaseevaporative cooling transformer using solid filling and liquid mixingtechnologies can be used not only in electromagnetic iron-separators andpower transformers, but also in various evaporative cooling electricalequipments. The research results in this paper are high valuable for practicalapplication obviously, and they will be very helpful for boosting financialbenefits greatly. Thanks to the excellent performance technically and brilliantbenefits economically, the solid filling and liquid mixing technologies mayarouse the attention of engineers who are engaging in electrical equipmentdesign and manufacture.
