Superchargers have become a focus of much research into new-energy vehicles, for which the cooling high-current cable cores is key problem that needs to be solved. To estimate influences different core structures liquid-cooled cables on fluid flow and heat transfer characteristics in circular pipes, nine helical with insertion smooth pipes were designed taking dimethyl silicone oil as coolant. The studied through computational dynamics (CFD) numerical simulation at inlet velocities (0.2–2.0...
A 3-D flow and heat transfer theoretical model was established for a 5 mm micro-fin tube to explore the characteristics of supercritical CO2/R41 therein under different pressures, mass fluxes, components. The research attempts provide reference selecting components working media setting pressure flux in application scenarios. Results show that closer temperature medium critical temperature, larger local convective coefficient (CHTC). CHTC at is 8 16 times higher compared with non-critical...
This research establishes 5 mm 3-D flow and heat transfer microfin tube theoretical models with three different geometric structures. Using these models, the thermal-hydraulic performances of supercritical CO2/R32 in tubes structures at various working conditions were investigated. The influences each factors (pressure, mass-flow, structures) on performance evaluated, respectively. Furthermore, orthogonal tests undertaken to obtain optimized combination overall performance. Results indicate...
