Abstract
The invention relates to a condenser (1) comprising an integrated collector (5) which is arranged parallel to one of the collector tubes (2) and is connected to said connector tube via two overflow opening (8 and 9). Said collector (5) is used to receive a drying/filtering unit (11). The condenser (1), consisting of tubes (3), ribs (4) and collector tubes (2), is produced by welding. According to the invention, the drying/filtering unit (11) is introduced into the collector (5) before the welding process and is positioned therein or connected thereto in a fixed manner. The collector (5) is then closed and the entire condenser (1) is welded. The connection between the drying/filtering unit (11) and the collector (5) is thus carried out before or during the welding process by means of welding. The invention is preferably used for air conditioning systems in motor vehicles.
