Abstract

A heat exchanger consists of a plurality of exchange tubes (1) arranged parallel to one another. For the passage of one of the media participating in the heat exchange, the cross-section of the exchange tubes has a width which is large in relation to the height. Fastened to each of the two flat sides (2) of the exchange tubes (1) are ribs (3) which are formed from a ribbed band (strip) (4) which is multiply deflected in a meandering fashion. In order to reduce the influence of any possible pollutants (pollution) on the heat transfer performance of the heat exchanger, the ribs (3) are provided with a plurality of openings (9). The cross-sections of these openings are respectively at least as large as the cross-section (Q), through which flow occurs, between two adjacent ribs (3). The ribs (3) are preferably fastened to the flat sides (2) of the exchange tubes (1) by means of a capacitor discharge welding process. <IMAGE>
