Definitions
- Heat exchanger in particular exhaust gas cooler
- the invention relates to a heat exchanger, in particular exhaust gas cooler of the type specified in the preamble of claim 1.
- DE 10 2009 050 884 A1 describes an exhaust gas heat exchanger, in particular for a motor vehicle, which comprises at least one diffuser for supplying and / or discharging an exhaust gas flow, an exchanger region and a housing through which a coolant can flow.
- the exchanger section is formed of a plurality of exchanger tubes extending in axial lease, which are connected at one end to a bottom in a fluid-tight manner.
- the invention has for its object to provide a heat exchanger of the type mentioned, in which the ground on the flange of the housing simple way is accurately positioned and a relative movement of the soil on the flange is prevented with certainty.
- the pins are provided diametrically opposite to the opening. As a result, the floor is most effectively fixed against rotation.
- the pins are surrounded at their foot by a circumferential groove. This avoids burr formation and high notch effect at the transition between the pin attachment and the housing end face (flange surface).
- the pins are bypassed by the cutter.
- the pin is not touched during milling.
- the circumferential groove preferably has a radius of 0.5 mm to 1.5 mm with respect to its cross section. The milling cutter works on the face at a distance of approx. 0.5 mm away from the pin.
- the pins and the corresponding recesses at least in sections one have elliptical and / or circular and / or angular and / or elongated contour.
- the pins can, for example, also at the very edge of the flange
- the pins have a height sufficient to protrude from the ground with the bottom adjacent to the flange.
- a bottom-mounted diffuser can be accurately positioned by gripping the pins into corresponding openings on the bottom-facing side of the diffuser.
- the diffuser is centered by means of the pins relative to the housing. This eliminates the need for time consuming interfacing at the end of the production line, saving investment in a dimension control facility.
- the bottom has a shape adapted to the shape of the flange of the housing. As a result, a large area uniform contact of the soil is achieved on the flange.
- protrusions or arms with threaded holes arranged therein are provided on an outer edge of the flange, and at the edge of the bottom projections and arms designed in the same way are provided with bores arranged therein.
- FIG. 1 is a view of a housing flange on a housing of a radiator, in particular exhaust gas heat exchanger,
- FIG. 2 shows a bottom for receiving the ends of heat exchanger tubes (winglets),
- FIG. 3 representation of an integrally formed on the housing flange arm with one of the
- Flange plane protruding pin, 4 shows a section of the housing flange with a corresponding section of the floor
- FIG. 6 shows a detail of the housing flange according to FIG. 4 with a detail of the bottom and a diffuser shown above, FIG.
- Fig. 7 is a view of a housing attached to the flange diffuser.
- Fig. 1 is a view of a flange 1 of a housing 2 of a heat exchanger 3, for example, an exhaust gas cooler shown.
- the flange 1 surrounds a substantially rectangular opening 4, which forms a shaft for receiving a heat exchanger block comprising a plurality of heat exchanger tubes (winglets).
- a pin 10 is disposed adjacent to the threaded hole 9, which protrudes perpendicularly from the flange surface of the flange 1.
- Such a pin 10 is also provided on the left in Fig. 1 arm 7.
- the pins 10 are located on relative to the flange surface diagonally opposite locations of the flange 1.
- the pins 10 are cast on the flange 1, d. H. they are generated when casting the housing 2 and do not need to be added later.
- Fig. 2 shows a bottom 11 with a plurality of openings 12, in which the ends of heat exchanger tubes received and materially connected, in particular welded.
- the shape of the bottom 11 corresponds to the shape of the flange 1 in Fig. 1 including the projections 6 'and 8' and the arms 7 '. By this shape of the bottom 11 results in a contact surface for bearing the bottom 11 on the flange 1.
- In the projections 6 ', 8' and arms T are holes or punched holes 13, which are congruent with the threaded holes 9 on the flange 1 (see Fig .. 1).
- bores 14 or openings are provided, which are suitable with regard to their position and size to receive the pins 10 (cf., Fig. 1), such that the pins 10 fit exactly into the holes 14.
- Fig. 3 one of the integrally formed on the flange 1 of the housing 2 arms 7 is shown, arranged in the arm 7 threaded bore 9 and the pin 10.
- the pin 10 has at its foot a circumferential groove 15, which also during casting of the housing 2 is already generated.
- the circumferential groove preferably has a radius of 0.5 mm with respect to its cross section.
- FIG. 4 shows that the bottom 11 is fed to the flange 1, which is however only the case when the bottom 11 is equipped with heat exchanger tubes 17, as shown in FIG.
- both pins 10 shown in Fig. 1 are inserted into the respective opening 14 in the bottom 11, whereby an exact positioning of the bottom 11 takes place on the flange 1.
- the pins 10 in the openings 14 and a subsequent relative movement of the bottom 11 is prevented from the flange.
- Fig. 5 it can be seen that the pin 10 protrudes from the bottom plane 11 placed on the flange 1 floor and that the bore 13 is congruent with the threaded hole 9. This ensures that the mounting screws can be reliably inserted during final assembly.
- FIG. 5 shows that the pin 10 protrudes from the bottom plane 11 placed on the flange 1 floor and that the bore 13 is congruent with the threaded hole 9. This ensures that the mounting screws can be reliably inserted during final assembly.
- FIG. 6 shows that the heat exchanger tubes 5 or their ends are received in the bottom 11.
- the block formed from the heat exchanger tubes 5 is inserted into the opening shown in Fig. 1, wherein the bottom 11 comes to rest on the flange 1.
- the exact positioning of the base 11 on the flange 1 takes place by the insertion of the in particular diametrically arranged pins 10 (see Fig. 1) in the holes 14, because the dimensioning of Pin 10 and bore 14 are selected to preclude relative sliding of the bottom 11 on the flange surface.
- the exact positioning also ensures that the holes or holes 13 are congruent with the threaded holes 9 and thus covering the threaded holes 9 is excluded. From Fig.
- a diffuser 16 is placed.
- This diffuser 16 has, on its surface facing the bottom 11, corresponding openings into which the pins 10 projecting beyond the bottom 11 are inserted, so that the diffuser 16 also assumes a precisely defined position.
- the diffuser 16 has a shape adapted to the shape of the bottom 11 of a contact surface, on whose outer edge also projections 6 and arms 7 are formed, as is the case on the flange 1 and bottom 11.
- the projections 6 and arms 7 of the diffuser 16 are also provided with holes 17 which are congruent with the holes 13 on the bottom 11 and the threaded holes 9, so that screws for fixing the diffuser 16 and the fixed bracing of the components 16, 11 and second can be inserted and tightened.
- Fig. 7 is a view is shown on the overall arrangement, wherein the diffuser 16 is fixed by means of screws 18 on the housing 2. All other reference numerals are identical to those of FIGS. 1 to 6 for the same parts.
- the shape of the pins 10 can be selected according to the application.
- the pins and the corresponding recesses have, at least in sections, an elliptical and / or circular and / or angular and / or oblong contour.
