Due to the excellent heat transfer characteristics, the spiral coil sub-cooled condenser(SCSCC) has a bright application for the prospective automotive air-conditioning system. The engine load and emissions can be diminished by increasing the coefficient of performance of the vehicular A/C unit because this load is the second power consumption unit after the engine. Experimentally, two different cross-sectional channel of SCSCC has been analyzed and then compared with CFD investigation. The CFD results revealed the generation of Dean vortices inside the refrigerant and illustrate the co-relationship among heat transfer rate and pressure loss inside SCSCC
