Abstract

A heat-exchanger tube block is disclosed having at least two header tubes (6, 7), which are C-shaped in cross section and each of which has a continuous longitudinal slot (10, 11). Flat tubes (2a, 2b) are inserted into the header-tube longitudinal slots. A cover-plate element (12) is provided which has a plurality of C-shaped openings and is fitted over one end of the at least two header tubes, so that the header tubes respectively fit into one of the openings and are secured in a fluid-tight manner. The tube-block can be used, for example, in an evaporator of CO2 air-conditioning installations for a motor vehicle.
