The invention relates to a fully-metal heat exchanger comprising flat tubes ( 1 ), which have two narrow sides and two wide sides ( 2, 3 ), and comprising fins ( 4 ) which form a block together with the flat tubes, and comprising either at least one tube plate ( 5 ) and one collecting tank ( 6 ), with edges ( 10 ) of the collecting tank ( 6 ) being connected, for example soldered, to edges ( 20 ) of the tube plate ( 5 ), or at least one collecting tank ( 6 ) which contains the tube plate, and having projections ( 11 ) which are arranged at intervals. The invention leads to a heat exchanger which has a small installation space requirement while having comparatively good thermal properties in that, according to the invention, the projections ( 11 ) engage in the ends of the flat tubes ( 1 ) in the region of the narrow sides ( 2 ). The production method according to the invention accordingly provides that the projections ( 11 ) are inserted into the ends of the flat tubes ( 1 ) approximately in the region of the narrow sides ( 2 ). |
