Since the ribs 22, 26 in the housing longitudinal direction L each have a substantially constant cross-sectional profile, these ribs 22, 26 can be provided in a simple manner in an extrusion process.
- the housing interior 16 is closed off by the second housing part 58 provided with a substantially flat plate 64 in this exemplary embodiment.

Further, the maximum overall length of the heat exchanger housing 10 is kept compact at the maximum possible axial length of the peripheral wall portion 14, so the first housing part 56.
- the first housing part 56 is connected to the third housing part 60 forming the combustion subrack region 28.
- the third housing part 60 has a connecting region 74 with a circumferential wall 76, which is dimensioned and substantially so is designed so that it continues the peripheral wall portion 14 axially.
- the circumferential wall region 14 has, in this second axial end region 72, a connection surface 78 which is oriented radially outwards and which surrounds the housing longitudinal axis L without interruption. This can be provided, for example, by removing a length section of the second heat transfer ribs 26 and also the radially outer region of the circumferential wall region 14 in this longitudinal region of the first housing part 56 by material-removing machining.

- a radially outwardly leading exhaust nozzle 52 is further provided in the region of the connecting region 74 and the peripheral wall 76 with an exhaust outlet opening 54 formed therein and open in the direction of the housing interior 16. Since the third housing part 60 has a comparatively complex structure, in particular with the exhaust nozzle 52 to be provided, which can not be produced with all its structural features in an extrusion process, this third housing part 60 is preferably provided as a cast component in a casting process. wherein, for example, for the third housing part 60, the same building material, as can be used for the first housing part 56, for example, aluminum or an aluminum-containing alloy. Also, the second housing part 58 may be constructed with the same construction material as the first housing part 56, and the third housing part 58th
- the in the Fig. 5 and 6 illustrated embodiment of a heat exchanger housing 10 differs from the above with reference to the Fig. 1 to 4 described embodiment is substantially in the construction of the second housing part 58.

- heat transfer ribs 102 are provided in association with the first heat transfer ribs 22 on the inner side 20 of the peripheral wall region 14. At least a portion of these, preferably all heat transfer fins 102 are positioned and / or dimensioned such that these first heat transfer fins 22 continue substantially continuously on the inner side 20 of the peripheral wall region 14. Thus, even in this area, in which the two housing parts 56, 58 adjoin one another, the exhaust gas flow in the housing interior 16 at the transition from the heat transfer ribs 102 to the first heat transfer ribs 22 is substantially not affected.
- heat transfer ribs 106 are provided on a side facing away from the housing interior 16 outside 104 of the wall 92 of the second housing part 58. These are preferably arranged or dimensioned such that at least a part of, preferably all heat transfer ribs 106 continue second heat transfer ribs 26 on the outer side 24 of the peripheral wall region 14 substantially continuously. Thus, the air flow on the outside of the heat exchanger housing 10 in the adjoining region of the two housing parts 56, 58 to each other is not substantially affected.
- a gap-like gap may be present, which is essentially formed by the length region in which the two connection surfaces 96, 98 overlap one another.
- the heat transfer ribs 106 provided on the outside 104 of the wall 92 could be guided in the direction of the housing longitudinal axis L into that region of the wall 92 in which the radially inwardly oriented connection surface 96 is provided.
- second housing part 58 has a comparatively complex, not in an extrusion process geometry, this is also preferably produced as a cast component in a casting process, in which case the same construction material as for the first housing part 56 and the third housing part 60 can be used.
- the first housing part is such that it has a substantially constant over its entire axial length cross-sectional geometry, this first housing part can be made in an extrusion process, which leads to a better material quality and avoids the introduction of a Entformungsschräge. Only in those axial end regions, where, due to the structure of a respectively adjacent housing part, a radially oriented connection surface is to be provided, is a mechanical or machining post-processing of such an extrusion component necessary in order to produce the area required for the production of the welded connection.
- the first housing part can be provided as an extruded component, this can be adapted in a simple manner to different dimensions of a heat exchanger housing to be constructed by appropriately sized lengths are separated from a strand produced by the extrusion process. Since a Entformungsschräge does not exist, has the peripheral wall area in all axial regions at the same radial distance from the flame tube, which favors the exhaust gas flow and improves the heat transfer capacity.
- the other housing parts to be connected with such a first housing part which, if required by the complex geometry of these components, for example as die-cast components, can be adapted to the structure of a respective heat exchanger housing to be fitted, so that ultimately a modular housing System can be provided, in which for different heater types, for example, different third housing parts can be combined with correspondingly shaped combustion subrack carrier areas with different sized first housing parts or differently designed second housing parts.
