Abstract

A heat exchanger for a heating device, especially a fuel value heating device, made up of at least two vertically aligned members, and, in each case, one cover at the end face, which form a combustion chamber, and laterally border at least one heating gas flue, that leads from the combustion chamber in the upper region downwards to an exhaust collector in the lower region, having heat exchanger surfaces which, on the heating gas side, are provided with elements that increase the size of surfaces, especially in the form of ribs, optionally having at least one middle member between the two bordering outer members, and having a plurality of channels guiding the heating medium flowing through in parallel and/or in series in the members and/or the covers. The present system provides a compact heat exchanger for a heating device, and which is light and is especially suitable for the fuel value operation. In the present system, the members and the covers are connected to one another at the end face to form a block that is leak-proof to the heating gas, whose channels guiding the heating medium correspond to one another. The heat exchanger surfaces, acted upon by heating gas, of two adjacent members, over their length have a greater distance from one another in the middle, and thus form a wider heating gas flue than in the edge regions, the ribs each having a greater height in the middle and overlapping one another over a greater surface than in the edge regions.
