Abstract
The present invention relates to a refrigerant condenser for motor vehicle air-conditioning systems of the type that include a tube/fin block, header tubes arranged on both sides of the tube/fin block and a collector arranged parallel to one header tube, wherein the header tubes have partitions for creating a multi-pass flow of the refrigerant, and the tube/fin block has an upper condensation region and a lower supercooling region. The collector is flow-connected via passage orifices to the condensation region, on the one hand, and to the supercooling region, on the other hand. The collector has approximately the same diameter or the same cross section as the adjacent header tube, and an additional container of larger cross section or larger diameter is provided for storing refrigerant and/or for receiving a dryer and/or filter. The container is connected to the collector, either in parallel or in series, via connecting lines, with one of the connecting lines being connected between the condensation region and supercooling region.
