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 are provided with tabs arranged in pairs at an angle to the flow direction, projecting from at least one wall of the channels, and a liquid cooling medium flows around the outside.
  • the channels are formed from disk-shaped heat exchange elements, between each of which a turbulence insert is arranged, which has the tabs arranged in pairs at an angle to the flow direction.
  • This heat exchanger known from DE-U 94 06 197.1 fulfills the task placed on it in a satisfactory manner.
  • the invention has for its object to provide a heat exchanger of the type mentioned, which can be produced in different sizes with essentially the same structure is, with not too high dimensional tolerances have to be maintained for the individual components.
  • a bundle of rectangular tubes is provided as channels for the exhaust gas, the ends of which are welded into grid-shaped tube sheets, that the bundle of rectangular tubes is surrounded by a sheet metal jacket which follows the contour of the bundle which enters with a cooling medium and is provided with a cooling medium outlet and which is welded to the tube sheets, and that the ends of the sheet metal jacket are provided with welded-on flange plates, each of which is open to the bundle of rectangular tubes by means of a central opening and which are provided with fastening means for fastening to tube pieces of an exhaust pipe .
  • the welded heat exchanger according to the invention essentially consists of sheet metal components that can be manufactured in a simple manner.
  • the welding is preferably carried out as laser welding or micro TIG welding.
  • the grid-shaped tube sheets which are stamped from sheet steel of approximately 1 mm to 3 mm in thickness, have openings in accordance with the number and arrangement of the rectangular tubes.
  • the distances between the rectangular tubes and thus the web width of the tube base varies depending on the mass flow of the coolant and is also on the order of 1 mm to 3 mm.
  • the outer contour of the tube sheets results from the number and arrangement of the flat tubes.
  • the sheet metal jacket is also produced in a simple manner from a steel sheet which has a sheet thickness similar to that of the tube sheets.
  • the sheet metal jacket can be folded in steps according to the contour of the tube sheets in a simple manner.
  • the flange plates provided with fastening means allow the heat exchanger to be arranged in a simple manner between two pipe sections of an exhaust pipe, for example in a manner similar to the arrangement of a catalytic converter.
  • the rectangular tubes are each formed from two tube shells welded together.
  • the pair of tabs can be attached directly to the rectangular tube or be part of this rectangular tube. However, they can also be part of inserts arranged in the rectangular tubes.
  • the flange plates are provided with threaded sleeves in essentially diametrically opposite areas. A screw connection with a counter flange of a pipe section of an exhaust pipe is thereby possible in a simple manner.
  • the sheet metal jacket is provided with a cooling medium inlet in the vicinity of the front flange plate in the flow direction of the exhaust gas and with a cooling medium outlet in the vicinity of the rear flange plate. This initially ensures that the cooling medium is passed in direct current to the exhaust gas through the heat exchanger. This ensures that the risk of steam formation on the inlet side of the exhaust gas is reduced since the cooling medium has the relatively lowest temperature here.
  • the cooling medium inlet and the cooling medium outlet are arranged on opposite sides of the sheet metal jacket. Because of this arrangement, the flow paths of the individual flow paths for the cooling medium around the rectangular tubes are essentially of the same length, so that a uniform flow around these rectangular tubes is ensured.
  • the sheet metal jacket is composed of two preformed sheet metal shells which are joined to the tube sheets by means of joint connections connect. After welding, the two sheet metal shells result in a rigid and pressure-resistant housing.
  • the provision of joint connections has the advantage that the elements to be welded have a certain degree of cohesion before welding, so that the welding process can be carried out relatively easily.
  • the flange plates connect to the sheet metal jacket by means of joint connections. It is also provided for the same purpose that the threaded sleeves connect to the flange plates by means of a joint connection. The welding process can thus be carried out relatively easily.
  • the heat exchanger shown in Figures 1 and 2 has a bundle of flat tubes (10) which have a wall thickness in the area have from 0.3mm to 0.4mm.
  • the ends of the rectangular tubes (10) are inserted into the tubular tube plates (11) and welded to them.
  • Such a tube sheet (11), which serves to hold 16 rectangular tubes, is shown in FIG. 7, for example.
  • These tube sheets (11) are punched from a steel sheet which has a sheet thickness in the order of 1 mm to 3 mm.
  • the webs between the openings which serve to receive the flat tubes have a width which corresponds approximately to the wall thickness of the rectangular tubes (10).
  • the arrangement of the openings and thus the webs of the tube sheets (11) is selected so that a circular or oval cross section is obtained in rough approximation.
  • the webs comprising the external rectangular tubes also have the same web width, so that the outer contour of the tube sheets corresponds to the contour of the tube bundle - increased by the web width.
  • the tube sheets (11) are welded into the ends of a sheet metal jacket (12), which is also indicated by dashed lines in FIG. 7.
  • the sheet metal jacket (12) consists of two half-shells made of sheet steel, which has a thickness which essentially corresponds to the thickness of the tube sheets (11).
  • the half-shells are shaped according to the outer contour of the tube sheets (11), for example edged or by means of a high-pressure forming process.
  • the two half-shells of the sheet metal jacket (12) are connected to one another by means of longitudinal weld seams (13).
  • the tube sheets (11) are provided with a total of four somewhat widened lugs (14), which are assigned corresponding recesses at the end of the two half-shells of the sheet metal jacket (12), so that a joint connection is hereby created.
  • Flange plates (15) are welded to the two ends of the sheet metal jacket (12), which are also stamped from sheet metal and have a sheet thickness similar to the sheet thickness of the tube sheets (11).
  • the flange plates (15) are in two diametrically opposite areas laterally over the contour of the Sheet metal over. In this area, the sheet metal jacket (12) is extended in the axial direction beyond the tube sheets (11) and inserted with these extended approaches into slot-shaped recesses (17) in the flange sheets (15). In this area, welding takes place from the outside of the flange plates (15), while in the remaining area, welding is provided from the other side.
  • the flange plates (15) have a central, preferably circular recess (18), the dimensions of which correspond to the preceding and following pipe sections, not shown, of an exhaust system or exhaust system of a vehicle.
  • the flange plates (15) are provided with threaded sleeves (19, 20) in the diametrically opposite regions which project outwardly beyond the sheet metal jacket (12).
  • the threaded sleeves (19) are inserted with an annular collar located on their open side into bores in the flange plates (15) and welded to them from the respective outside of the flange plates (15).
  • the threaded sleeves (19) In the area of their closed side, the threaded sleeves (19) have an annular collar with which they are inserted into a retaining web (21). This retaining web (21) is welded to the threaded sleeves (19) and the sheet metal jacket (12).
  • the connecting pipe (24) and the threaded sleeve (20) are each welded to one another with a weld seam (25).
  • the outside of the weld seam (25) is ground off.
  • a lateral recess (26) is then milled into the connecting pipe (24).
  • the threaded sleeves (20) are welded with their ring collar (23) into recesses in the flange plates (15) and with welded the flange plates (15).
  • the connecting pipes (24) are additionally welded to the sheet metal jacket by means of retaining webs (27).

They are covered by welded cover plates (28) which are welded to the sheet metal jacket (12), the retaining webs (27), the connecting pipe (24), the threaded sleeves (20) and the flange plate (15).
  • a kind of water box is thus formed in the area of the cutouts (26) between the holding webs (27) and the flange sheets (15), in the area of which the sheet metal jacket is provided with an inlet opening.
  • the connecting pipes (24) and the associated water boxes are on opposite sides of the sheet metal jacket, so that an approximately Z-shaped flow path is created for the cooling medium indicated by the arrows (29).
  • This flow path has approximately the same flow path in the area of all rectangular tubes (10), so that there is a very good and uniform flow around the rectangular tubes (10).
  • the coolant inlet in FIG. 1 above is arranged on the side on which the exhaust gas indicated by the arrow (30) is also located, while the coolant outlet is located on the side indicated by the arrow ( 31) indicated outlet side of the exhaust gas. The cooling medium and the exhaust gas thus flow in cocurrent within the heat exchanger.
  • the rectangular tubes are provided with tabs (32) which are arranged in pairs and project inwardly from opposite walls and which are arranged obliquely to the flow direction of the exhaust gas that they diverge from a narrowest point at an angle of about 40 °.
  • the rectangular tubes are each welded together from two tube shells (10 ') which are welded together on their narrow sides.
  • the pipe shells have a sheet thickness of about 0.3mm to 0.4mm.
  • the tabs (32) have approximately the same thickness and a length of about ten times their sheet thickness. They diverge from a narrowest point at which they are about 1.2 mm apart at an angle of 40 °.

  • the tube halves (10 ') are provided with slots into which the tabs (32) are inserted and then welded to the tube halves (10').
  • the tabs (32) can be provided on their side facing the tube halves (10 ') with one or more elevations, so that they are welded to the tube halves (10') using the known stud welding technique, so that the Tight welding is not necessary.
  • the tabs (32) of the two tube halves are arranged opposite one another.
  • the tabs (32) of the two tube halves (10 ') are arranged off-center such that the tabs (32) of the upper tube half and the lower tube half (10') are offset in the transverse direction to one another.
  • the distance between the tabs (32) in the flow direction of the exhaust gas is approximately 30 mm.
  • the tabs (32 ') are each formed out of the tube half (10') by deep drawing and compression. This eliminates the need for a welding process, particularly sealing welding in the area of the tabs (32 ').
  • Fig. 4a it is further shown that the tube half (10 ') is provided with an outward button-like shape (33).
  • a component which is a folded sheet metal part (34) which forms pairs of tabs (35).
  • This component (34) can be attached to the tube halves (10 ') in the region of the web connecting the tabs (35) by means of spot welding. This also eliminates sealing welding.
