Definitions
- the invention relates to an arrangement of a charge air cooler in an intake pipe, wherein the charge air cooler has a radiator block through which charge air can flow and through the intake pipe has a first opening through which the intercooler can be inserted into the intake pipe,
- Charged air coolers are used in supercharged engines for cooling the charge air. This is necessary because the intake air is heated by the compression in a turbocharger. This leads to a decrease in the density of the intake air, which effectively leads to a lower proportion of oxygen in the combustion chamber charge.
- the cooling by the intercooler causes, in contrast to the compression, an increase in density, with the result that in the combustion chamber of the internal combustion engine high-density intake air is supplied.
- the amount of oxygen needed for combustion is particularly high in high density air.
- the intercooler In today's applications in the automotive industry, the arrangement of the intercooler has prevailed in the intake manifold of the internal combustion engine for this purpose.
- the intercooler is usually inserted through a lateral opening in the intake pipe and secured by means of a usually materially connected to the intercooler connection flange on the intake manifold.
- a second bearing for the charge air cooler may be provided at the wall of the intake pipe opposite the insertion opening.
- a disadvantage of the prior art is that by this method of installation vibrations on the intake manifold and voltages that may arise due to not 100% tolerances between the flange of the charge air cooler and the intake manifold, are transferred directly to the intercooler.
- the object of the present invention to provide an installation concept for suction pipe integrated intercooler, which allows even long intercooler easy and safe to assemble in the intake manifold.
- the aim is to provide an installation concept which is particularly advantageous for the charge air cooler with regard to the vibrations that occur.
- the object of the present invention is achieved by a ... with the features of claim 1.
- an arrangement of an intercooler in an intake pipe wherein the intercooler has a charge air permeable radiator block and through the intake manifold has a first opening through which the intercooler is inserted into the intake manifold, wherein the intake pipe has a second opening, which to the first Opening is arranged substantially opposite and can be closed by a housing part. It is also advantageous if the intercooler can be fixed to the first opening of the intake pipe.
- the insertable into the intake manifold end of the charge air cooler has a projection and the housing part has a recess, wherein the projection and the AüsEnglishung are plugged into each other, or if the insertable into the intake manifold end of the charge air cooler has a recess and the housing part has a projection, wherein the projection and the recess are inserted into one another, by these configurations of the charge air cooler and the housing part in such a manner, the charge air cooler can be inserted in the housing part and fixed in its installed position.
- the housing part is connectable to the intake pipe. By connecting the housing part with the intake pipe, the second opening of the intake pipe is closed and sealed.
- a sealing means can be introduced between the housing part and the intake pipe and if a sealing means can be introduced between the flange and the intake pipe.
- FIG. 1 shows in the left half a perspective view of an intake manifold of an internal combustion engine with built-in intercooler and in the right half of the intercooler in the dismantled state
- Fig. 2 shows a section through the center plane of the intercooler and the intake pipe in the built-in shown in Figure 1 State
- FIG 3 shows a section through the center plane of an intercooler and an intake pipe in an embodiment according to the invention.
- FIG. 1 shows an external perspective view of an intake pipe 5 in the left half of the drawing.
- This intake pipe 5 serves to supply air to an internal combustion engine (not shown in the drawing). Compressing the intake air in a turbocharger or compressor heats the air. As a result, the density of the air is reduced, which would lead to a poorer filling of the combustion chambers of the internal combustion engine.
- a charge air cooler 4 is installed for the purpose of cooling the air, which is supplied via the intake manifold 5 to an internal combustion engine and thus the increase in the density of the intake air in the intake manifold 5, a charge air cooler 4 is installed.
- the more accurate internal structure of the intake manifold 5 is not described in detail at this point, since this is not essential to the invention. From the left figure of Figure 1, the principle of incorporation of the intercooler 4 in the intake pipe 5 is apparent.
- the right half of Figure 1 shows the intercooler 4, which is installed in the left half of Figure 1 in the intake manifold 5.
- the charge air cooler 4 shown in FIG corresponds in its construction known from the prior art intercoolers.
- the intercooler 4 In addition to a radiator block 1 5, which consists of a plurality of coolant-carrying cooling tubes, which are flowed around by an air to be cooled, the intercooler 4 has outer walls 7. Laterally on one of the manifolds of the intercooler 4, a flange plate 12 is attached. This serves for fastening the intercooler 4 on the intake manifold 5.
- the intercooler 4 has two coolant connection pieces 16a, 16b.
- a centering means 17 is arranged, which serves for the additional storage of the intercooler 4 in the intake manifold 5.
- intercooler is not further described at this point, since this is not essential to the invention.
- intercoolers in different designs is conceivable.
- U-shaped intercoolers with a deflection in the interior as well as the use of a straight-flow intercooler without deflection, which have the inlet and the outlet at opposite ends.
- FIG. 2 shows a section through the center plane of the installed intercooler 4 in the intake pipe 5.
- the section through the intake pipe 5, which has intake pipe inner walls 9, can be seen in particular.
- the inner region of the intake pipe 5 in this case has dimensions that allow insertion of the charge air cooler 4.
- a recess in the intake pipe is provided, which serves to receive the centering means 1 7, which is attached to one of the outer ends of the charge air cooler 4.
- the intercooler could have a recess in which engages a projecting portion of the housing part, or the intercooler has a mandrel which engages in the housing wall of the intake pipe.
- the flange 12 closes flush with the outer wall of the loading luftroh res 5 and can be fixed on the screw 13 on the intake manifold 5.
- a sealant 19 such as an O-ring seal is provided.
- the radiator block 15 is thus effectively exposed to the air flow which flows in the interior of the intake pipe 5, whereby a heat transfer from the air flowing through the cooling medium, which flows in the interior of the intercooler 4, is promoted.
- FIG. 2 represents in its execution the current state of the art with all the disadvantages described in the introduction.
- FIG. 2 In contrast to the intake pipe 5 shown in FIG. 1 and the arrangement of the intake pipe 5 and the installed intercooler 4 shown in FIG. 2, an intake pipe 5 with two openings 1, 1 1 facing one another is now shown in FIG. In addition to the insertion opening 1 1 through which the intercooler in the intake pipe 5 is inserted, the, the opening 1 1 opposite opening 1 in the intake manifold 5 is shown.
- This opening 1 in the intake pipe 5 is closed by a housing part 2 of the intake pipe 5.
- This housing part is about Versch raubungen 14 on the intake manifold 5 fixed.
- the housing part has in its interior a bearing point 3 for the centering means 17 of the intercooler 4.
- the screw 14 are executed here by screw-through holes with an enlarged diameter, whereby a balance of tolerances in the mounting plane of the housing part 3 is possible.
- a sealing means 19 is arranged, as well as between the housing part 2 and the intake pipe 5, a sealing means 18 is arranged.
- the sealing means 18, 19 are used to better seal the intake manifold 5 to prevent leaks and concomitant pressure losses, for example.
- connection techniques for fixing the housing part on the intake manifold such as riveting, gluing or clipping are conceivable. It is also possible under the flange and the lid to install additional sealant to prevent leaks.
- the intercooler 4 is stored in the installed state in two places. On the one hand on the Fianschplatte 12 of the intercooler 4 and the other in the connected to the intake pipe 5 housing part 2. This comes the intercooler 4 in particular with regard to the vibrations resulting in operation of the internal combustion engine to good.
- the intercooler is characterized particularly vibration resistant mounted in the intake manifold 5, which is beneficial to a longer life of the intercooler.
- the fact that the centering means 17 of the intercooler, the housing part 2 of the intake pipe 6 is taken for a stable hold of the charge air cooler is provided within the intake manifold 5.
- the arrangement of the bearing between the housing part and the inserted intercooler may also differ from that shown here.
- the housing part has an inwardly standing in the intake manifold intent, which engages in a recess in the end region of the charge air cooler.
- the exact configuration of the bearing pair of housing part and intercooler must be designed according to the application and the assembly process accordingly.
- the intercooler is supported with its centering on the intake pipe itself and the housing part takes over only the function of closing the intake pipe.
