generic Heat exchangers are of the prior art already known and can be used for indirect cooling a first medium to be cooled by means of another Medium used as a coolant well.

For example, in the patent DE 103 29 153 B4 a heat exchanger described in which profiled, thin-walled and deep-drawn Plati NEN are arranged one above the other, that the superposed boards form channel profiles through which different warm media can be passed, so that a warmer medium can be cooled by a cooler medium. By means of the multiplicity of printed circuit boards, the channels of the heat exchanger can be made relatively easy to construct.

A simplified structure with regard to the formation of channels on a heat exchanger shows a plate heat exchanger from the patent DD 243 087 A1 in which a profile of the plate heat exchanger is formed by means of a continuous profiled sheet metal strip, which seen in the flow direction meandered over one another. Due to the meander-shaped profiled sheet metal strip partitions of the channels of the plate heat exchanger can be structurally particularly easily made by means of a single continuous profiled sheet metal strip, so that a heat exchanger is structurally further simplified.

It Object of the present invention, a structure of a generic To further simplify the heat exchanger, at the same time Extension of the application possibilities of the heat exchanger.

The The object of the invention is a heat exchanger, in particular of a motor vehicle, with a heat exchanger block comprising a corrugated profile with radial and axial openings and comprising means for closing the radial openings solved the corrugated profile, wherein the closure devices are arranged radially on the profile, in which the corrugated profile first channels for conducting a first medium and second Forms channels for conducting a second medium, and at which of the heat exchangers is characterized by that the radially arranged closure means both radial openings as well as axial openings of the corrugated profile and / or at the axial openings an axial collection box is arranged axially on the heat exchanger block, wherein at least two channels by means of the axial collection box axially spatially interconnected.

Especially in that the radially arranged closure devices are not only radial openings of the corrugated profile but according to the invention at the same time also close axial openings of the corrugated profile can, can the present heat exchanger very easy to build.

is cumulatively or alternatively at at least one axial end of the heat exchanger block arranged an axial collection box, by means of which channels the heat exchanger block axially spatially with each other can be connected, the field of application of the present Heat exchanger structurally very easy versatile be extended.

Especially It is advantageous that the heat exchanger block of the heat exchanger ideally only one single corrugated profile to all major channels to realize the heat exchanger block.

By This simple structure allows the individual components put the respective heat exchanger together and ideally in a single soldering process within soldered to each other, provided that the components consist of solderable materials. It goes without saying that in the present case also other joining methods advantageous for Application can come, such as welding and gluing the components.

In the present case, the term "heat exchanger" describes any device by means of which thermal energy is transferred from a first medium, which can flow in first passages of the heat exchanger, to another medium, which can flow into the other, further passages of the heat exchanger can be that the first medium is cooled here. In particular, in the present case heat exchangers of motor vehicles are detected, such as cross-flow heat exchangers used there, in which coolant is passed liquid and / or gaseous through cooling passages of the heat exchanger. Due to the versatile and structurally simple design of the present heat exchanger can advantageously be the most different heat exchanger structurally exceptionally easy to implement, such as an exhaust gas heat exchanger, in particular an exhaust gas heat evaporator, a condenser or other high-temperature and low-temperature radiator on a motor vehicle. The present heat exchanger can be used with its corrugated profile advantageously continue to cool battery cells, electronic components or the like. Also for room air conditioning, the heat exchanger can be used.

Of the Term "heat exchanger block" describes in this context, essentially that area of a Heat exchanger, in which mainly a transfer of heat energy from one first warmer medium to another colder Medium can take place.

at the "wavy profile" may be present to act on any form, which meanders are designed so that they have several channels structurally particular can train easily. It is understood that a variety to manufacturing process is available, by means of which a corrugated profile can be made. The corrugated profile can here from a folded, folded or rolled sheet material be prepared. In addition to such mechanical forming processes a corrugated profile can also be made primitive, for example by means of an extrusion process in which the corrugated profile extruded out of an extruder. Accordingly sees an advantageous embodiment also before that the corrugated profile of a folded sheet or extruded Material is made.

On Reason of the meandering shape of the corrugated Profiles can structurally channels on corrugated profile be easily formed, with first channels of the corrugated Profile radially only from a first direction are accessible while second channels the corrugated profile radially exclusively from a preferably the first direction opposite, further direction accessible are, unless the channels are arranged radially Locking devices are closed. Axial are all channels readily accessible, unless they are arranged radially Locking devices are closed.

Advantageous can even longer channels on the heat exchanger be formed when the corrugated profile transverse to the longitudinal extent meandering of the heat exchanger block is arranged.

Favorable Way, the corrugated profile forms common partitions the first channels and the second channels. insofar The heat exchanger can be made of fewer individual components be put together.

A Heat transfer between two media in can flow in adjacent channels, can intensify when the corrugated profile has a surface with imprints having. Such embossments can for example Winglets within the channels condition or other Mirkostrukturen, which an improvement in performance, pressure drop and / or contamination of the channels, such as deposits can achieve.

In The channels thus produced can be different Media preferably in layers through the heat exchanger be directed, the media being a liquid or have a gaseous state of matter.

Of the The term "axial openings" describes the openings at the top of the corrugated profile, with an axial view a head side of the corrugated profile is a substantially sinusoidal Course of the corrugated profile can be seen. In this context are the axial openings of the corrugated profile in terms the heat exchanger block from axial ends of the Heat exchanger block accessible from, unless provided by the means for axial closure the axial openings are closed.

In contrast, The term "radial openings" describes transversely to the above-mentioned head pages extending openings on the corrugated profile, which in terms of the heat exchanger block are radially accessible.

With the term "axial collection box" is a device described by means of which on the one hand an axial termination of the Heat exchanger block, in particular an axial Completion of the corrugated profile, and on the other hand, a spatial Connection of axial openings of channels of the corrugated Profile can be created.

Especially It is advantageous if the radially arranged closure devices Means for axially closing the axial openings of the corrugated profile, whereby the axial openings can be reliably closed. For example The radially arranged closure devices here have tines on which radially into the channels of the corrugated profile protrude into it and in this case the axial openings of the corrugated Can close profiles.

Preferably, the means for axial sealing in the region of a head side of the gewell th profile, so that they do not have to protrude directly into the channels, but only axially abut the corrugated profile, with a particularly good solder connection between the tines and the corrugated profile can be made when the tines are arranged within the channels , So project radially into the channels of the corrugated profile.

constructive The axial openings can be particularly simple axially closed by means of the radially arranged closure devices be when the radially arranged closure means comb-shaped formed means for closing the axial openings of the corrugated profile. For example, end regions the locking devices bent by 90 ° and as from each other spaced tines are formed, each radially in a channel of the corrugated profile can protrude.

are the means for axially closing a first radial arranged closure device to a further radially arranged Closure device of the heat exchanger block arranged, the heat exchanger can be special stable and in particular very pressure resistant to be built. Furthermore can comb-shaped means for closing the axial openings of two on a head side opposite radially arranged closure devices axially one above the other be arranged lying, so that in this case a double tine wall thickness can result.

Especially tines protruding into the channels of the corrugated profile can be particularly intimately connected with the corrugated profile be when the radially arranged locking devices prongs include, which are U-shaped. By means of a U-shape can structurally on the means for axial sealing simply a circumferential collar can be formed, which is a larger Contact surface on the means for axial Ver close ready so that this larger area with can be soldered to the corrugated profile. hereby Advantageously, the risk of leaking solder joints be reduced. In addition, larger-scale Soldering areas the strength of the heat exchanger continue to increase.

A preferred embodiment provides that the radial arranged closure means first channels and / or second channels of the heat exchanger block radially and / or axially close. This can be a Heat exchanger with a variety of channels, through which for the purpose of heat transfer different media can flow, extraordinary be realized compact.

The Possible use of the present heat exchanger is further advantageous increased when the heat exchanger cumulatively or alternatively has a radial collection box, whereby channels of the heat exchanger block can also be connected to each other radially. Such Radial collection boxes can be particularly simple be integrated in the construction of the heat exchanger, when the radially arranged closure means a radial Include collection box, by means of which at least two channels radially spatially connectable to each other.

At It should be noted that in particular an axial Collection box weight reduced on the basis of the invention Heat exchanger can be provided if the axial collection box made of plastic and mechanically is attached to the heat exchanger block. For example such a connection succeeds well with the prior art known Wellenbördelungen.

Especially It is advantageous in this context, if at the heat exchanger block, in particular on the corrugated profile, axially a bottom with Wellenschlitzbördelungen and / or means for clawing are arranged.

For example is such a floor with the heat exchanger block soldered and forms at one axial end of the heat exchanger block a particularly good mounting option for the axial collection box. But also rivet, clip and / or clip connections are possible here alternatively.

A further improvement of heat transfer can be achieved at the present heat exchanger, if within the first and / or second channels turbulators are arranged.

The in the 1 and 2 shown heat exchanger 1 can be used on a motor vehicle (not shown here) as an indirect cooler. The heat exchanger 1 has a heat exchanger block 2 which basically consists of a corrugated profile 3 (such as in the 3 shown). The wavy profile 3 has a meandering body 4 made of a sheet metal material 5 folded. Here, the corrugated profile 3 a folding direction 6 on which transverse to the longitudinal extent 7 of the heat exchanger 1 and in particular transversely to the longitudinal extent of the heat exchanger block 2 or the corrugated profile 3 runs, with the longitudinal extensions 7 identical. By means of the corrugated profile 3 can first channels 8th and second channels 9 at the heat exchanger block 2 are formed, wherein the corrugated profile 3 at the same time the partitions 10 (numbered here only as an example) between the first and second channels 8th and 9 forms.

Through the first channels 8th can in the assembled state of the heat exchanger 1 a first medium (not shown here) through the heat exchanger block 2 while flowing through the second channels 9 another medium (not shown here) through the heat exchanger block 2 can flow.

All channels 8th and 9 have radial openings 11 and axial openings 12 , where the channels 8th respectively. 9 depending on the meandering body 4 radially only from one side 13 or 14 are accessible. Axially seen are the channels 8th and 9 in the wavy profile 3 both from a first side of the head 15 as well as from a second side of the head 16 accessible.

The channels can be radial 8th and 9 of locking devices 17 (only exemplified here) for closing the radial openings 11 be closed. Because the locking devices 17 radially to the corrugated profile 3 In the present case, they are also arranged as radially arranged closure devices 17 designated. So that the radially arranged closure devices 17 with radial narrow ends 18 of the corrugated profile 3 can be connected particularly well, has the corrugated profile 3 at the Schmalenden 18 a fold 19 on. The fold 19 can provide a sufficiently large solder surface, via which a secure and permanently sealed solder joint between the corrugated profile 3 and the radially arranged closure devices 17 can be guaranteed.

channels 8th and 9 can at least partially at the radial openings 11 of the corrugated profile 3 spatially interconnected when the radially arranged closure devices 17 radial collection boxes 20 include, as in this embodiment, the heat exchanger 1 can be seen. At the radial collection boxes 20 can be particularly advantageous radial nozzle 21 Be provided (only exemplified), which as a supply or discharge pipe for fluid media with respect to the heat exchanger 1 can serve. In particular, with the radial collection boxes 20 Be redirected to media and connected channels 8th or 9 be initiated.

Advantageously, the radially arranged closure devices 17 also the axial openings 12 of the corrugated profile 3 close by the radially arranged closure devices 17 medium 22 for closing the axial openings 12 in the form of comb-like prongs 23 (see also 4 to 6 ) which radially into the channels 8th respectively. 9 of the heat exchanger block 2 can reach into it. To a particularly intimate solder joint between the individual comb-like prongs 23 and the wavy profile 3 to obtain, have the comb-like prongs 23 additionally each still a U-shaped cross-section 23A (see in particular 5 ), resulting in extra large contact surfaces 25 at the comb-like prongs for soldering available.

Due to the fact that the radially arranged closure devices 17 medium 22 for closing the axial openings 12 include builds the present heat exchanger 1 very compact, because it will close the channels 8th respectively. 9 still few components needed.

So completely closed axially, the heat exchanger is suitable 1 in that a first medium according to a first feed direction 24 in the heat exchanger 1 is initiated, first channels 8th of the heat exchanger 1 flows through and according to a first discharge direction 25 again from the heat exchanger 1 is discharged. Accordingly, a second medium according to a second feed direction 26 also in the heat exchanger 1 be introduced, wherein the second medium, the heat exchanger 1 in second channels 9 flows through and the heat exchanger 1 subsequently according to a second discharge direction 27 leaves again. One of the two media has absorbed heat energy and another of the two media was able to emit heat energy.

Advantageously, the four radially arranged closure means with varied means 22 for closing the axial openings 12 be equipped, depending on what kind of ducting on the heat exchanger 1 to be realized.

Especially if all components of the heat exchanger 1 are made of a solderable material, the components can be soldered together in a known manner in a single soldering process.

An advantageous development of a heat exchanger 1 shows the further embodiment 30 from the 7 and 8th in which the heat exchanger 1 only with two radially arranged closure devices 17 is equipped, but on a first side of the head 15 a first axial collection box 31 and on a second side of the head 16 a second axial collection box 32 is arranged. By means of the two axial manifolds 31 and 32 For example, suitable media can also be transferred axially into a heat exchanger block 2 of the heat exchanger 1 be initiated or discharged. For this purpose, for example, channels are suitable 8th of the heat exchanger 1 with their axial openings 12 by means of the axial collection boxes 31 and 32 interconnected. The axial collection boxes 31 and 32 are each with an axial neck 33 to connect to other components (not shown here) equipped. For example, a first medium according to a first feed direction 24 axially in the heat exchanger 1 initiated and according to a first discharge direction 25 discharged again after the first channels 8th from a first side of the head 15 to a second head page 16 flowed through. A second medium, however, according to a second feed direction 26 radially in the heat exchanger 1 introduced and according to a second discharge direction 27 from the heat exchanger 1 discharged again, after the second medium, the heat exchanger 1 could flow through; and by the second channels 9 , however, axially by means of tines 23 one of the radially arranged closure devices 17 are closed. Suitable radial manifolds 20 and radial nozzles 21 are at the two radially arranged closure devices 17 on a first page 13 of the heat exchanger 1 available.

The two axial manifolds 31 . 32 are designed here as a curved U-profile. Each of the U-profiles is axially on the heat exchanger block 2 plugged, in this embodiment 30 at the heat exchanger block 2 two opposite edges 34 are provided, to which the axial manifolds 31 and 32 each can be soldered.

The in the 9 and 10 shown and alternatively designed axial collection box 31 is made of a U-profile, which laterally with covers 35 closed so that the axial collection box 31 in this embodiment directly as a closed unit 36 axially on one side of the head 15 a heat exchanger block 2 can be soldered. Advantageously, in this case heat exchanger block 2 sided edges 34 (please refer 8th ) accounted for. The heat exchanger block 2 has a wavy profile 3 on.

To generic axial manifolds 31 or 32 especially good on a heat exchanger block 2 can attach to a head side 15 of the heat exchanger block 2 outside of the heat exchanger block 2 in addition a revolving floor 37 ( 11 ) be provided. The revolving floor 37 is preferably simultaneously with the other components of a heat exchanger 1 soldered. The revolving floor 37 may be on an outer panel 38 of the heat exchanger block 2 support, with the revolving floor 37 on a side facing away from this 39 a groove 40 has, in which a suitably trained end 41 an axial collection box 31 can intervene. This allows a particularly good solder joint between the axial collection box 31 and the surrounding floor 37 getting produced. The heat exchanger block 2 also includes a corrugated profile in this embodiment 3 from a sheet metal material 5 , by means of which first channels 8th and second channels 9 of the heat exchanger block 2 are formed. The first channels 8th open into the axial collection box 31 and are thus connected to each other via this. The second channels 9 of the heat exchanger block 2 are at their ends by means of U-shaped tines 23 one radially on the heat exchanger block 2 arranged closure device 17 (not to be seen here, see for example 6 ) locked. Here, the U-shaped cross-section is particularly good 23A with the extra large contact surfaces 23B to recognize, by means of which the tines 23 a very intimate solder joint to partitions 10 can produce.

An alternative rotating floor 37 is at one in the 12 and 13 shown heat exchanger block 2 intended. The heat exchanger block 2 again has a wavy profile 3 on which a radially arranged closure device 17 attached, which with closure means 22 axial openings 12 of the heat exchanger block 2 closes. The revolving floor 37 stands here on a head side 15 axially across an axial end of the heat exchanger block 2 out, leaving an axial collection box 31 (please refer 13 ) in the surrounding soil 37 can be inserted and soldered. In this embodiment, the radially arranged closure device comprises 17 a radial collection box 20 with a radial neck 21 ,

In the latter revolving floor 37 can advantageously be an axial collection box 31 be secured by means of a positive connection, when the axial collection box 31 not to be soldered, for example because it is made of a plastic. Because of the revolving floor 37 relatively high above the axial end of the heat exchanger block 2 sticks out, offers the revolving floor 37 axially sufficient space for providing a known Wellenschlitzbördelung or a known claw connection. By means of such a positive connection, the axial collection box 31 alternatively on the heat exchanger block 2 be attached when the axial collection box 31 has corresponding counter-structures (not shown here).

In the in the 14 shown heat exchanger block 2 is on a wavy profile 2 a radially arranged closure device 17 soldered, with comb-like prongs 23 in first channels 8th of the heat exchanger block 2 protrudes into it and the first channels 8th thereby closes. Second channels 9 of the heat exchanger block 2 are not axially closed, but are in the second channels 9 additional turbulators 42 arranged, by means of which a better heat transfer between a first medium in the first channels 8th and a second medium in second channels 9 can be achieved.

In the 15 and 16 are representations 43 and 44 different imprints 45 and 46 a sheet metal material 5 for a wavy profile 3 shown. The first coinage 45 allows a rhomboid structure while further imprinting 46 simulating a surface of a shark skin, thereby reducing the risk of pressure drop in channels of the corrugated profile 3 can be reduced.

The cutout 47 from the 17 illustrates first channels 8th and second channels 9 by means of a partition wall 10 a wavy profile 3 are separated from each other. In the first channels 8th are winglets 48 integrated while in the second channels 9 further microstructures 49 available. By means of such variations in the channels 8th and 9 can improve the performance of a heat exchanger 1 be increased.
