Study on Optimization of Copper to Aluminum for Locomotive Finned Tube Radiator

The influence of the improvement finned tube radiator unit structure on fluid flow and heat transfer effect locomotive was studied. A saw-toothed fin with aluminum instead copper proposed to keep position size flat hot water pipe unchanged. CFD simulation analysis carried out by ICEPAK17.0, under conditions an ambient temperature 24.6 °C, atmospheric pressure 85,040 Pa air density ? = 0.94 kg/m3, compare changes velocity field, turbulence field synergy angle. sawtooth new sink increases fluid, reduces thickness outer boundary layer pipe, strengthens radiator. Finally, baffle height, wing window width angle were selected, coefficient three low, medium high used as indexes analyze each parameter performance results show that dissipation serrated sheet is higher than sheet, increased about 1.3%, average reduced, improved, reduced 2.3°, has better performance. factor greatest least pressure. When 0.15 mm high, largest, height change highest included Angle effect, higher. By changing structure, thermal can be improved.
