Definitions
- the invention relates to a pipe arrangement for a charge air cooler and a charge air cooler with such a pipe arrangement.
- the invention further relates to an internal combustion engine with such a charge air cooler.
- the invention relates to a method for producing the above-mentioned tube arrangement.
- DE 10 2012 008 700 A1 discloses a heat exchanger in the form of a charge air cooler, in which compressed charge air is cooled by means of a cooling liquid in at least two immediately adjacent stages.
- a cooling liquid for the charge air are flow channels, provided for the coolant flow paths.
- the heat exchanger is formed by a single stack of one-piece plates.
- Conventional intercoolers are thus typically constructed in the manner of a heat exchanger, which is part of a coolant circuit and is flowed through by a coolant, which in turn couples thermally to the charge air to be cooled. The heat removed from the charge air is absorbed by the coolant, whereby it evaporates.
- a central component of a charge air cooler known from the prior art represents a tube arrangement with tubes stacked along one another along a stacking direction and through which the charge air to be cooled flows. Between the individual tubes coolant channels are provided, which in turn are flowed through by coolant. In other words, coolant channels and tubes alternate along the stacking direction.
- DE 103 28 746 A1 describes a device for exchanging heat with at least three flow devices, through which at least one flowable fluid flows.
- the device comprises at least two flow assemblies with at least two flow elements which are arranged such that the latter are alternately flowed through by different fluids. These are directly positive-locking and / or material-locking and / or force-locking and / or via fluid distribution devices. connected fluidly connected at least with respect to a flow device in series.
- GB 2 057 564 A also discloses a two-stage heat exchanger based on the principle of a fluidic series connection.
- the basic idea of the invention is accordingly to design the pipe arrangement explained above in such a way that the fluid pipes provided for flowing through the charge air to be cooled pass along their longitudinal direction at a predetermined point an expansion formed integrally on the fluid tubes, in the region of which they have locally an enlarged flow cross-section. Since a cooling channel is provided in each case along the stacking direction between two adjacent fluid pipes, such a widening of the fluid pipes causes a fluidic interruption of the cooling channel along the longitudinal direction and thus its division into a first and a second cooling channel region, so that the two regions are separate Coolant circuits can be used.
- the widening essential to the invention can be introduced into the fluid pipes in a production-technically simple manner, for example, by means of a shaping method familiar to the person skilled in the art as "tucking-in".
- a shaping method familiar to the person skilled in the art as "tucking-in”.
- inflating the pipes are expanded by mechanical stretching and pressing in a negative shape.
- a forming by means of internal high-pressure forming with water is conceivable.
- the pipe arrangement according to the invention proposed here permits the production of a charge air cooler with a compact construction, so that only very little installation space has to be reserved for the arrangement of the charge air cooler, for example in a motor vehicle.
- the tube arrangement presented here due to its structurally very simple construction manufacturing technology is easy to manufacture, resulting in cost advantages in the production.
- the pipe arrangement according to the invention is equipped with a plurality of fluid pipes - that is, with at least two such fluid pipes - which are stacked along a stacking direction.
- Said stacking device extends orthogonal to a longitudinal direction of the fluid pipes.
- a cooling channel is provided in each case between two fluid pipes adjacent in the stacking direction, wherein each cooling channel is delimited along the stacking direction by a first tube wall of a first fluid tube and by a second tube wall of a second fluid tube adjacent to the first fluid tube.
- each fluid tube has a widening of the first and / or second tube wall along the longitudinal direction, thereby achieving the desired separation of each fluid channel into a first cooling channel region and a second cooling channel region fluidly separated therefrom.
- the entirety of the first cooling channel regions can be integrated into a first coolant circuit
- the entirety of the second cooling channel regions can be integrated into a second coolant circuit which is fluidically separated from the first.
- the widening of the fluid channel takes place along the stacking direction.
- the separation of a fluid channel can be achieved by widening the tube walls delimiting the channel along the stacking direction.
- first and second tube walls in the region of the expansion materially connected proves to be particularly favorable.
- a fluid-tight separation of the respective fluid channel is ensured in a first and second region by said expansion (s).
- such a cohesive connection can also be dispensed with.
- Such a scenario is particularly suitable when the respectively prevailing fluid pressure in the two coolant areas is substantially the same, because in this case there is no excessive pressure gradient between the two coolant areas; in the case of such a pressure gradient unilaterally acting on the expansion (s) forces leading to a deformation of the pipe walls in the region of the expansion and thus ultimately undesirable leakage effects between could lead the two cooling channel areas are in the case of identical fluid pressures but largely excluded.
- the idea essential to the invention of interrupting a fluid channel by widening the tube walls extending in the longitudinal direction can also be applied to the end of the fluid channel that is end-side relative to its longitudinal side.
- the fluid channels are each closed fluid-tightly at an end relative to the longitudinal end portion and / or a first end portion opposite the second end portion by widening the first and / or second tube wall.
- a particularly compact design of the charge air cooler using the tube arrangement can be achieved if the fluid tubes of the tube arrangement are designed as flat tubes.
- each fluid pipe may have a pipe height measured along the stacking direction, which is at most one fifth, preferably at most one tenth, of a pipe width.
- the tube width is defined by a width direction which extends orthogonally both to the stacking direction and orthogonal to the longitudinal direction.
- a rib structure in at least one cooling channel, preferably in all cooling channels, on which the tube walls of the fluid pipes adjoining in the stacking direction can be supported.
- the tube arrangement may comprise at least five, preferably at least ten, most preferably at least twenty, fluid tubes which are stacked on top of one another along the stacking direction.
- a measured in the stacking directiondekanal- height is at most a fifth, preferably at most one tenth of the tube height of the fluid pipes.
- the tube arrangement comprises a first tube part which comprises the first cooling channel region and a second tube part which comprises the second cooling channel region.
- the two cooling channel areas are thus formed as separate components, in such a way that the first tube part can be fastened to the second tube part or vice versa.
- the widening essential to the invention with respect to the longitudinal direction is provided at an end of the second tube part facing the first tube part, so that the first tube part can be inserted into the second tube part, or vice versa.
- the second pipe part extends the first pipe part along the longitudinal direction.
- first and second pipe parts may be formed integrally, i. the entire tube assembly is integrally formed.
- the invention further relates to a charge air cooler for an internal combustion engine having a pipe arrangement one or more of the aforementioned features.
- the intercooler according to the invention is equipped with a first coolant circuit as well as with a second coolant circuit which is fluidically separated therefrom.
- the first cooling channel region of each cooling channel is fluidly connected to the first coolant circuit, the second cooling channel region of each cooling channel with the second coolant circuit.
- the invention also relates to an internal combustion engine for a motor vehicle with a charge air cooler presented above.
- the invention relates to a method for producing a pipe arrangement.

- FIG. 2 shows a detailed representation of the example of FIG. 1,
- Figure 1 illustrates a pipe assembly 1 according to the invention in a perspective view.
- the pipe arrangement 1 comprises a plurality of fluid pipes 2, through which the charge air of an internal combustion engine to be cooled flows can.
- five fluid pipes 2 are shown by way of example; of course, in variants, however, a larger number, for example at least five, at least 10, or even at least 20 fluid pipes are conceivable.
- the term "plurality" includes all pipe arrangements 1 with at least two fluid pipes 2.
- the fluid pipes 2 are stacked along a stacking direction S which extends transversely to a longitudinal direction L of the fluid pipes 2.
- Each fluid tube 2 comprises a first and a second tube wall 3 a, 3 b, which delimit a fluid path 4 formed by the fluid tube 2 in the stacking direction S.
- the two tube walls 3a, 3b may be integrally formed.
- the fluid pipes 2 are also designed as flat tubes.
- Each of the fluid pipes 2 has a pipe height measured along the stacking direction S, which is at most one fifth of a pipe width.
- Said tube width is defined by a width direction B which extends orthogonally to both the stacking direction S and the longitudinal direction L.
- the pipe height can amount to at most one tenth of the pipe width.
- a cooling channel height measured in the stacking direction S is at most one fifth, preferably at most one tenth, of the pipe height of the fluid pipes 2.
- a cooling channel 5 is formed, through which a coolant can flow.
- Each cooling channel 5 is thereby bounded along the stacking direction S by a first tube wall 3a of the first fluid tube 2, which faces the second fluid tube 2, and by a second tube wall 3b of the second fluid tube 2, which in turn faces the first fluid tube 2.
- the fluid pipes 2 have in the stacking direction S extending widenings 6 - see.
- the detailed representation of Figure 2 - the first and second pipe wall 3a, 3b, which subdivide each cooling channel 5 with respect to the longitudinal direction L into a first cooling channel region 5a and a second cooling channel region 5b which is fluidically separated from the latter.
- the widening 6 is formed in the example shown in the figures by the two tube walls 3a, 3b delimiting the cooling channel 5 in the stacking direction and is integrally formed thereon.
- the widenings 6 can be introduced into the tube walls 3 a, 3 b of the fluid pipes 2 in a manner which is simple in terms of production technology, for example by means of a forming process familiar to the person skilled in the art as "flare-ups".
- the widenings 6 can each be formed by only one of the two tube walls 3a, 3b, in order to achieve the desired effect of interrupting the respective cooling channel 5 along its longitudinal direction L.
- the first and second tube walls 3a, 3b are in the region of the widenings 6 in each case materially connected to one another by means of a solder connection. In this way, a fluid-tight separation of the respective fluid channel 5 in the first and second region 5a, 5b is ensured.
- FIG. 3 now illustrates a variant of the pipe arrangement of FIGS. 1 and 2, in which the widenings 6 of the fluid pipes 3 presented above are additionally provided on an end section 7 a of the fluid pipes 2 relative to the longitudinal direction L and on an end section 7 b opposite the first end section 7 a.
