EN The air cooled automotive condensers under study are of brazed aluminium tube and center, consisting of one row array of horizontal parallel multi-port flat tubes with corrugated louver fins on the air side. Each tube is with a number of smooth parallel minichannels for internal flow of refrigerant. The analysis uses decomposition of the condenser along refrigerant flow path into specific different zones as follows: two single phase zones, namely: superheated and subcooled, and a few zones of two phase flow that can appear along some specific condensation paths to be: annular/intermittent/bubble or annular/annular-wavy/intermittent/bubble or annular/wavy/stratified. The approach presented is based on two phase flow regimes and corresponding experimental correlations for heat transfer and pressure drop. The heat transfer prediction is performed using [epsilon] - NTU[o] methodology.Results of the analysis refer to variations in the flow regimes and vapour quality along the condensation path, overall heat transfer rate, and for particular zones: contributed thermal resistances, heat transfer effectivenesses, flow lengths, heat transfer rates.
