Definitions
- the invention relates to a crossflow cooler for motor vehicles, consisting of horizontally arranged tubes with ribs in between, the Pipes lead into collecting boxes at both ends; on one of the longitudinal and Collection boxes with transverse walls are parallel to this also a longitudinal and transverse walls having expansion vessel, one of which a longitudinal wall shaped degassing line is provided, which with the Expansion vessel and the header is in flow connection to Gas inclusions in the coolant from the collection box in the Lead expansion tank.
- cross-flow cooler described is known from DE 33 41 390 A1.
- Known cross flow coolers consist of the expansion tank and the Collection box from a single part made by injection molding Plastic. Located between the expansion tank and the header a molded connecting line connecting the degassing line with the Expansion vessel connects.
- the expansion tank and the collection box have a small distance from each other, which may be due to the special manufacturing process is required so that this design is not considered can be viewed particularly compact.
- The also has similar disadvantages
- Cross flow cooler which is known from DE 34 46 007 C2 and the rest also corresponds to the generic term.
- the object of the invention is an extreme in the cross-flow cooler compact design of his collection box with the expansion tank achieve or preserve while reducing the number of individual parts.
- the solution according to the invention provides that the collection box and that Expansion vessel from two arranged in the direction of their longitudinal axes and parts connected by joining technology is formed by means of a common Wall are separated from each other, with the degassing line in the seam is arranged.
- An independent, secondary solution provides according to the invention that the Collection box and the expansion tank from two towards their Longitudinally arranged and joined parts are formed, which are separated from each other by a common wall, the Degassing line and at least one additional line in the seam are arranged, the additional line with the collecting box and communicates with the expansion tank.
- the direct joining technology connection preferably a welded or adhesive connection between the Collection box and the expansion tank ensures a very compact Shape because there is no space-consuming, unused space between the Collection box and the expansion tank is available. Since the lines in the seam between the header and the expansion tank trained - that is, part of the seam - they can be used in the production the collecting tanks and the expansion tank are designed in the same way that they arise when the same is put together. Thus for the Case that both the collection boxes and the expansion tank from Plastic, no metal lines required, which makes the Disposal is improved.
- This feature of the invention also creates also the prerequisite for the collection box and the Expansion vessel can be easily manufactured using injection molding technology, in particular from can be removed from the mold.
- the expansion tank and the header boxes are preferably made of plastic or also formed from aluminum and by means of known joining processes in the joining seam connected. They are preferably welded together or bonded.
- the cross-flow cooler consists, in a manner known per se and therefore not to be described in detail, of horizontal tubes 20, which are flat tubes, and ribs 21 arranged between them .
- the tubes 20 connect the two header boxes 1 and 2, so that the cooling liquid of the Motor vehicle can flow to be cooled by means of cooling air which flows through the ribs 21 perpendicular to the image plane of FIG. 1.
- the tubes 20 open into tube sheets 23, specifically in openings (not shown) there, in which they are tightly connected, for example by means of soldering.
- the collection boxes 1; 2 are mechanically connected with their border 32 at the edge of the tube sheets 23 , a seal being arranged between them. (Not shown)
- the coolant flows from the cooling circuit (not shown) into the cooler at the header 1 via the inlet connector 25 and back into the circuit at the outlet 24 of the header 2 .
- an expansion vessel 3 is connected, and that at the joint 7, which extends in the exemplary embodiment in a plane 13, joined together by welding.
- the collection boxes 1; 2 and the expansion vessel 3 are made of plastic. They are shaped in such a way that they can be easily manufactured using injection molding technology.
- a suitable connection method is also an adhesive connection, in particular if, as shown in these exemplary embodiments, the collecting boxes 1; 2 and the expansion tank 3 are made of plastic.
- detachable connections that have seals are not completely excluded.
- the degassing line 8 and an additional line 4 are located in the plane 13 of the joining seam 7.
- Both lines 4; 8 fluidly connect the header tank 1 to the expansion vessel 3, which are otherwise separated from one another by means of the common wall 6 .
- the degassing line 8 is connected clearly below the level ( arrow ) of the cooling liquid in the expansion tank 3 by means of a bore 35 to the header tank 1 , while the additional line 4 has a connecting bore 36, at the top, to the valve cover connection 27 .
- FIG. 3 Since FIG. 1 is only a relatively abstract representation, the arrangement of the lines 4; 8 in the joining seam 7 are referred to FIG. 2.
- the lines 4 and 8 have a rectangular cross section, as shown in FIG. 2.
- FIG. 3 shows another embodiment in a more detailed manner than in FIGS. 1 and 2.
- the degassing line 8 is partially formed there in the elongated longitudinal wall 11 of the header tank 1 .
- the other part of the degassing line 8 is located in the longitudinal wall 15 of the expansion vessel 3.
- Both parts have a U-shaped cross-section, so that they get an approximately rectangular cross-section after the connection by welding, the rectangular cross-section not being particularly important, because Both parts could, for example, also be semicircular, so that there is an approximately round cross section of the lines 4 ; 8 results.
- the degassing line 8 is fluidly connected at the lower end by means of a bore 35 to the header tank 1 .
- the degassing line 8 opens into the collecting tank 1 with a bore 28.
- the additional line 4 is on the other, opposite, elongated longitudinal wall 10 of the collecting tank 1 and also in the corresponding longitudinal wall 9 of the expansion tank 3 been ordered.
- the fluidic connection to the collecting tank 1 is provided here by means of the bore 26 at the lower end of the line 4 and above 36 to the base 27 of the valve cover.
- the valve cover not shown here, is equipped in a known manner with a safety function in order to prevent the coolant from being ejected.
- the additional line 4 of the exemplary embodiment has the following function: During driving operation, the locking force of the valve cover or the pressure in the expansion vessel 3 is somewhat reduced by means of the additional line 4 in order to relieve the cooling system. When the engine is switched off, the coolant is reheated because cooling air no longer flows through the radiator and the stored heat is not dissipated. In this situation, the additional line 4 ensures that the locking force rises again to the original value, the valve cover fulfilling its sealing function. If the longitudinal walls 10 and 11 run parallel to one another, both lines 4, 8 are also arranged parallel to one another. In other versions, not shown, it is of course also possible to deviate from the parallelism if the function of the lines 4, 8 is fulfilled.
- the expansion vessel 3 extends with its longitudinal axis 5 only over part of the length of the header tank 1 .
- this is a measure at the discretion of the person skilled in the art, which he can take as a function of the required volume of the expansion vessel 3 or of existing installation restrictions of the cross-flow cooler in the motor vehicle.
- FIG. 4 is a cut-away representation of an embodiment in which only the additional line 4 is provided, which is formed between the longitudinal wall 9 of the expansion vessel 3 and the elongated longitudinal wall 10 of the collecting tank 1 .
- the connection is made by welding.
- the degassing line 8 is the degassing line 8 , which is required in all versions.
- FIG 5 shows the expansion vessel 3 of a further embodiment, in which the two lines 4 and 8 are arranged parallel to one another on a longitudinal wall 15 of the expansion vessel 3 . With 7 the entire joining seam was designated in the plane 13 the welded connection is made.
- FIG. 6 shows the connection between the expansion vessel 3 and the collecting tank 1 in this embodiment in cross section.
- parts of both lines 4; 8 only formed on the longitudinal wall 10 of the collecting tank 1 , so that they complete lines 4; 8 result when assembling and welding the expansion vessel 3 with the collecting box 1 .
- the elongated longitudinal and transverse walls of the collecting tank 1 and the longitudinal and transverse walls of the expansion vessel 3 were equipped with a peripheral edge flange 33 . The welding connection can thus be simplified.
- the expansion tank 3 also has a return port 34, which also serves to vent the cooler and the system.
