Definitions
- the invention relates to a heat exchanger for cooling Exhaust gas from an internal combustion engine with a plurality of channels for guiding the exhaust gas, which is inclined to the flow direction of the exhaust gas arranged in pairs, from at least one wall of the channels protruding tabs and on the outside with a liquid Coolant can flow around.
- the invention has for its object a heat exchanger to create the type mentioned, which at essentially same structure can be manufactured in different sizes is, for the individual components none too high dimensional tolerances must be observed.
- This object is achieved in that as channels for the exhaust gas a bundle of rectangular tubes is provided, the ends of which are welded into grid-shaped tube sheets that the bundle is surrounded by rectangular tubes with a sheet metal jacket, which the Contour of the bundle follows, which enters with a cooling medium and is provided with a cooling medium outlet and with the Tube sheets is welded, and that the ends of the sheet metal jacket are provided with welded flange plates, each through a central opening to the bundle of rectangular tubes are open and with fasteners for fastening are provided on pipe sections of an exhaust pipe.
- the heat exchanger according to the invention consists in essentially made of sheet metal components that are manufactured in a simple manner can be. Welding is preferred as laser welding or micro TIG welding.
- the lattice-shaped Tube sheets made of sheet steel from about 1mm to 3mm thickness are punched, according to the number and Arrangement of rectangular tubes breakthroughs.
- the distances of the Rectangular tubes and thus the web width of the tube sheet varies depending on the mass flow of the coolant and is also in the range between 1mm and 3mm.
- the outer contour the tube sheets result from the number and arrangement of the flat tubes.
- the sheet metal jacket also becomes easier Made of sheet steel, the one of the tube sheets has similar sheet thickness.
- the sheet metal jacket can be in Steps according to the contour of the tube sheets in simple Way be edged.
- the provided with fasteners Flange plates allow an arrangement of the Heat exchanger between two pipe sections of an exhaust pipe, for example in a manner similar to the arrangement of a catalyst.

- the pair of tabs can be attached directly to the rectangular tube or Be part of this rectangular tube.
- the flange plates in diametrically opposite one another Areas are provided with threaded sleeves. This is a screw connection with a simple Counter flange of a pipe section of an exhaust pipe possible.
- the sheet metal jacket near the in the flow direction of the Exhaust front flange plate with a coolant inlet and near the rear flange plate with a coolant outlet is provided. It is first achieved that the cooling medium in direct current to the exhaust gas through the heat exchanger is directed. This ensures that the danger of Vapor formation on the inlet side of the exhaust gas is reduced is because here the cooling medium is the relatively lowest temperature having.
- cooling medium inlet and the cooling medium outlet on opposite Sides of the sheet metal jacket are arranged. Because of this arrangement are the flow paths of the individual Current paths for the cooling medium around the rectangular tubes in the essentially the same length, so that a uniform flow this rectangular tubes is guaranteed.
- the sheet metal jacket is composed of two preformed sheet metal shells is that by means of joint connections to the tube sheets connect.
- the two sheet metal shells result after welding a rigid and pressure-resistant housing.
- the provision of joint connections has the advantage that those to be welded Elements a certain cohesion even before welding have, so that the welding process is relatively simple can be carried out.

- the two half-shells of the sheet metal jacket (12) are Longitudinal weld seams (13) joined together.
- the tube sheets (11) with a total of four somewhat widened approaches (14) provided the corresponding Cutouts at the end of the two half-shells of the sheet metal jacket (12) are assigned, so that hereby a joint connection is created.
- flange sheets (15) At the two ends of the sheet metal jacket (12) are flange sheets (15) welded, which are also stamped from sheet metal and which is a sheet thickness similar to the sheet thickness of the tube sheets (11) exhibit.
- the flange plates (15) are diametrically divided opposite areas laterally over the contour of the Sheet metal over. In this area the sheet metal jacket (12) extended in the axial direction beyond the tube sheets (11) and with these extended approaches into slit-shaped recesses (17) of the flange plates (15) are inserted. In this A weld is made from the outside of the area Flange plates (15) ago, while in the remaining area a weld is provided from the other side.
- the Flange plates (15) a medium, preferably circular Recess (18), the dimensions of which precede and follow, Pipe pieces, not shown, of an exhaust system or exhaust system of a vehicle.
- the threaded sleeves (20) shown in Fig. 8, on their open side assigned to the flange plates (15) with a Ring collar (22) are also provided on their closed Side with a ring collar (23) with which they are each inserted into a connecting pipe (24).
- the connecting pipe (24) and the threaded sleeve (20) are each with a weld seam (25) welded together. The outside the weld seam (25) is ground off. After that, in the connecting pipe (24) milled into a lateral recess (26).
- the threaded sleeves (20) are with their ring collar (23) welded into recesses in the flange plates (15) and with welded the flange plates (15).
- the connecting pipes (24) are additionally attached to the sheet metal jacket by means of retaining webs (27) welded on.
