Definitions
- the invention relates to a method for introduction at least one flat tube insertion slot in a collecting tube, in which in a first step a saw cut for the sawed respective flat tube insertion slot in the header and in a subsequent second step the flat tube insertion slot by means of one in the saw cut area punching slot stamp is formed.
- a process is suitable, for example, for introducing a or several flat tube insertion slots in manifolds of air conditioning heat exchangers, as used in motor vehicles as evaporators or condenser or gas cooler can be used.
- the length of the cross Longitudinal axis of the collecting pipe introduced saw cut at least twice the wall thickness of the collector pipe is smaller than the inside pipe diameter to choose so that in the punching step the front area of the diaphragm walls over the outer jacket of the Manifold is pushed outwards and the slot length becomes larger than the inside diameter of the header pipe.
- the first step is a saw slot across the entire desired slot width introduced, namely deeper than the wall thickness of the header, so that the individual chambers or longitudinal channels of the same reached, but not to the longitudinal median plane of the Collection tube.
- the second sawing step then becomes the first Saw step introduced saw slot on a smaller one Width deepened so that in the web areas, which the separate individual chambers, shoulders or shoulders formed become. These serve as stop surfaces for what is to be inserted Flat tube, with the result that when plugged in Flat tube connecting channels between the chambers remain.
- the slot length is chosen to be somewhat smaller than the effective one inner manifold width, i.e. than the outside width of the header minus the double pipe wall thickness.
- the invention is a technical problem of providing a new method of the type mentioned with which one or more flat tube insertion slots with advantageous slot contour and / or in advantageous Have it inserted into a collecting tube.
- the invention solves this problem by providing it a method having the features of claim 1, 2 or 3.
- the method according to claim 3 is particularly suitable for multi-chamber manifolds and is designed so that when punching the respective web area of the header pipe, the two adjacent Separates manifold chambers, deeper than that Level of a manifold wall area that acts as a flat tube insertion stop is pushed in this way to a Chamber connection channel to form.
- the flat tube insertion stop various possibilities. This is how he can do further training of the invention according to claim 4 include stop surfaces, that of the inner wall area of the two outer manifold chambers are formed. This inner wall area can e.g. around a rear chamber wall area in the flat tube insertion direction act or, as in an embodiment of the invention provided according to claim 5 to a formed during punching Shoulder in the inside of the two outer ones on the narrow side Collecting tube wall regions.
- the flat tube insertion stop one or more protrusions that are punched in each Web area between two chambers are formed.
- the figures illustrate examples of the insertion of a respective flat tube insertion slot into a single-chamber or multi-chamber manifold which is comparatively thick-walled and is therefore suitable for heat exchangers with high pressure loads, for example for evaporators and gas coolers of CO 2 air conditioning systems, as are increasingly used in motor vehicles.
- FIGS. 1 to 4 illustrate the introduction of a respective longitudinal slot 2 into a single-chamber manifold 1, in which, as is known, a pipe end of a flat heat exchanger twisted by 90 ° can be inserted and connected to the manifold in a fluid-tight manner.
- the longitudinal slot or slots are introduced in a two-step process. First, as shown in FIGS. 1 and 2, a saw cut 2 with a length a 1 and a width b 1 is sawn into the collecting pipe 1 at the desired location. The saw cut 2 is introduced to a depth d 1 which is smaller than the wall thickness D of the collecting tube 1. As a result, in this sawing step, no sawdust gets into the interior 3 of the collecting tube 1.
- the sawing cut can also be made to a depth greater than the collecting tube wall thickness D, ie the sawing cut produced in this first process step then forms a saw slot penetrating the collecting tube wall. In this case, sawdust can be removed in a corresponding cleaning step if necessary.
- the desired flat tube insertion slot is produced radially from the outside into the area of the saw cut 2 by means of punching with a slot punch (not shown).
- 3 and 4 illustrate the flat tube insertion slot 4 thus formed.
- the slot punch used and consequently the flat tube insertion slot 4 punched by it have a length a 2 greater than the saw cut length a 1 and a width b 2 greater than the saw cut width b 1 .
- the excess length a 2 -a 1 and the excess width b 2 -b 1 of the slot punch compared to the saw cut 2 are selected such that there is a constant height h of the passage 5 along the entire flat tube insertion slot 4.
- FIG. 5 shows a variant of the method in which the length oversize and the width oversize of the slot punch are selected in relation to the saw cut previously introduced in such a way that in the narrow area of a flat tube insertion slot 4a formed therewith with passage 5a there is a greater passage height c 2 and in the wide slot area a smaller one Passage height c 1 result.
- the passage height and a flat tube import bevel which is preferably formed by appropriately shaping the passage, can be influenced by material properties, for example by the hardness of the header tube material used.
- the bevel at right angles to the pipe extension can be influenced by the flank angle of the slot punch.
- the width and length of the saw cut determine the so-called manifold blockage through the passage formed or the inserted flat tube.
- preferred dimensioning ratios for pulling through have a ratio of saw cut length a 1 to slot punch length a 2 between about 0.2 and about 0.95 and a ratio of saw cut width b 1 to slot punch width b 2 between about 0.3 and about 0.95 include.
- flat tube insertion slots have to be inserted in the collecting tube are preferably provided in the sawing step saw all associated saw cuts in one operation and in the subsequent stamping step all flat tube slots in a further single operation by punching train.
- a slot punch can be used with any other dimensions, especially one that is only longer, but not a larger width, or just a larger width, but has no greater length, so that then only in A passage on the narrow-side or broad-side slot area arises.
- FIG. 6 illustrates in a cross-sectional view the insertion of a flat tube insertion slot 6 into a three-chamber manifold 9, which has three longitudinal chambers or channels 7a, 7b, 7c, which are arranged parallel to one another and are separated from one another in pairs by a web area 8a, 8b ,
- this flat tube insertion slot 6 a saw cut is first made in the desired slot length S 1 to a depth d, which in turn is preferably slightly less than the tube wall thickness D, so that no sawdust reaches the header tube channels 7a, 7b, 7c. Subsequently, the flat tube insertion slot 6 in the form shown in FIG. 6 is produced by punching with a suitably designed slot punch into the saw cut area.
- the slot punch preferably has a somewhat larger width than the saw cut, so that an inward-facing passage 10 is formed in the slot area on the broad side.
- the slot punch is designed such that it presses in the web areas 8a, 8b during punching, corresponding bulges 11a, 11b forming on the opposite side of the collecting tube, and forming projections 12a, 12b on the pressed-in web surface 13a, 13b , which act as a stop surface for the flat tube to be inserted.
- the multiple channels can be one or several multi-channel flat tubes inserted into the collecting tube 9 a fluid in parallel across the plurality of manifold ducts 7a, 7b, 7c supplied or removed from these become.
- FIG. 7 and 8 show a slot stamp 14 which in Stamping step to form the flat tube insertion slot 6 from Fig. 6 can be used.
- Fig. 7 shows the slot stamp 14 in a narrow side view
- Fig. 8 in a plan view on a broadside.
- the Slotted stamp 14 on its front active side 14a is suitable designed in a special way. From the broad sides to the middle of the stamp 14b it tapers to a point.
- FIG. 9 illustrates a variant of the exemplary embodiment from FIG. 6, in which connection channels between the header tube channels 7a, 7b, 7c are also created in the punching process by pressing in the web regions 8a, 8b, but without the projections 12a, 12b in the FIGS indented web areas 8a, 8b of the example of FIG. 6 are necessary to prevent a complete closure of these connecting channels by the inserted flat tube. Rather, the latter is prevented in the embodiment of FIG.
- FIG. 10 shows a further variant of the exemplary embodiment from FIG. 6 without the web area projections 12a, 12b, reference symbols being used for the same elements as in FIG. 9 for the sake of clarity.
- a shoulder or a shoulder 18a, 18b is formed laterally on the outside on the inner walls of the two outer header pipe channels 7a, 7c, respectively, by appropriate design of the slot stamp and the selection of a suitable slot length S 11 Height of a desired flat tube insertion level N A1 .
- the web areas 8a, 8b are again pressed in by the appropriately designed slot punch to a level T which lies in the flat tube insertion direction behind the flat tube insertion level N A1 .
- the flat tube comes to a stop when it is inserted against the two shoulders 18a, 18b, so that its front end lies at the insertion level N A1 as desired.
- the connecting channels created by pressing in the web areas 8a, 8b between the manifold chambers 7a, 7b, 7c remain at a height
- the inventive two-step process an advantageous introduction of longitudinal or transverse flat tube slots in a single-chamber or multi-chamber manifold, especially in a comparatively thick-walled collecting pipe, by insertion a saw cut and subsequent punching with a Slot temple.
- the geometry of the insertion slot leaves choose by the shape of the slot stamp.
