Definitions
- the invention relates to a header pipe for a heat exchanger with one or more slots made by internal die-free punching or internal high pressure forming for inserting a respective flat tube, and to a method for producing such a header pipe.
- An important area of application is heat exchangers in the form of evaporators and condensers or gas coolers of motor vehicle air conditioning systems.
- EP 0 198 581 B1 and US 5,052,480 disclose manifolds with a number of transverse slots each, into which flat tube ends of a heat exchanger block constructed from parallel flat tubes are inserted. Due to the transverse position of the slots, the manifold diameter must be kept larger than the slot length.
- the manifolds have a tube wall thickness that is many times smaller than their diameter.
- the collecting pipes of EP 0 198 581 B1 have indentations in the collecting pipe in the areas of the slots which form inwardly curved passages, the outside pipe diameter being outside the slot area is approximately one and a half times larger than in the slot area.
- transverse slots in the form of inward-curved passages are introduced into a manifold by punching by means of an inner die, for which purpose an inner die is inserted into the manifold and the slots from the outside into the by means of a suitable stamp Manifold wall are punched.
- transverse slots it is known to provide collecting tubes with slots running parallel or at an acute angle to the tube longitudinal axis, into which twisted flat tube ends are inserted, see, for example, the patent US Pat. No. 3,416,600 and the published patent applications EP 0 845 648 A2 and DE 197 29 497 AI.
- the invention has the technical problem of providing a collecting tube of the type mentioned at the outset which can be produced with relatively little effort and which is also particularly suitable for applications with high pressure loads, such as
- the invention solves this problem by providing a manifold with the features of claim 1 and a method for manufacturing manifolds with the features of claims 4 or 5.
- the ratio of the outside pipe radius to the pipe wall thickness has a value of less than five, that is, based on its outside pipe radius, the collecting pipe has a comparatively high pipe wall thickness, which makes it suitable for applications with high pressure loads, such as are present in automotive air conditioning systems that work with the refrigerant C0 2 .
- Pipe wall thicknesses between 1.8mm and 2.5mm can be provided.
- the header tube with this high tube wall thickness can be provided with relatively little effort by punching without internal dies or internal high pressure forming with elongated slots, inserted into the associated flat tube ends of a heat exchanger and soldered tightly or otherwise fixed gas-tight.
- a material with a hardness between 35 H v and 80 H v is selected for the header pipe.
- the slots of inwardly curved passages are formed in such a way that the ratio of the tube outer diameter outside the slot area to that in the slot area is between 1.02 and 1.5.
- one or more slots are made in the manifold by internal die-less punching or hydroforming, which are oriented parallel or at an acute angle to the longitudinal axis of the manifold.
- a manifold manufactured in this way is particularly suitable for heat exchangers in which flat tubes with twisted ends are used, which are oriented at an appropriate angle to the longitudinal axis of the manifold due to the twisting.
- a flat piece which can be solder-plated if necessary, is first bent to a blank to form the manifold, the remaining longitudinal gap then being soldered or welded tightly.
- the slots required for inserting heat exchanger flat tubes are either pre-ground into the flat piece or only into the blank bent out of the flat piece by internal die-free punching or broken in after the soldering or welding of the longitudinal gap.
- a solder-plated flat piece is used according to claim 6, so that a corresponding solder-plated manifold is then available, which facilitates sealing the longitudinal gap and / or flat tube ends inserted into the slots.
- the longitudinal gap is soldered in a joint soldering process in which the other components of the heat exchanger are soldered at the same time, so that overall only one complete soldering process is required for the production of the heat exchanger.
- punctual heat treatment and / or mechanical weakening is provided at the locations of the manifold at which the slots are to be made, which facilitates the insertion of the slots without an internal matrix.
- 1 is a schematic, partial side view of a collecting pipe min slots made parallel to the pipe longitudinal axis
- FIG. 3 is a fragmentary plan view of a flat piece that can be used to produce the manifold of FIG. 1,
- FIG. 4 shows a side view of the header pipe blank formed by bending the flat piece from FIG. 3,
- Fig. 5 is a partial side view of a manifold with two slots and adjacent to each other in the circumferential direction
- Fig. 6 is a cross-sectional view of a manifold with two separate longitudinal collecting channels.
- the collector tube 1 shown in sections in FIGS. 1 and 2 is circumferential, i.e. on its tubular casing, provided with a series of slits 3a, 3b, 3c, 3d, 3e, 3f which follow one another in the direction of the longitudinal tube axis and which are of an elongated shape adapted to the cross-sectional shape of flat tube ends to be inserted. They run with their longitudinal extension parallel to the pipe longitudinal axis or pipe jacket line 2 and follow one another with the formation of corresponding web areas 4a, 4b, 4c, 4d, 4e with the same, slight spacing. It is understood that depending on the need, i.e. depending on the sequence of the flat tube ends to be inserted in a heat exchanger flat tube block configuration used, any other sequence of slots is possible, e.g. a sequence of further spaced pairs of slots, each consisting of two closely adjacent slots.
- the slots 3a to 3f can be introduced by a punching process, in which the collecting tube 1 is surrounded by a two-part outer die, the lower die half of which supports the collecting tube 1 and the upper die half of which has a corresponding number of spaced slots, through which the corresponding punch punches plunge and thereby Slots 3a to 3f "tear" into the collecting tube 1 as inward-facing passages.
- the slots can be introduced partially by means of suitable punches, with the outer tube being only partially guided on the outer circumference become. As can be seen more clearly from FIG.
- the collecting tube 1 has, through the inwardly bent through slots 3a to 3f, a tube outer diameter D x in the respective slot region which is smaller than the tube outer diameter D outside the slot regions, ie at the level of the webs 4a, 4b , 4c, is.
- outer diameter is to be understood in the present context in a broad sense in that it generally denotes the transverse extent, even in the case of non-circular cross-sectional shapes. It can be seen that the "tearing" or punching of the slots 3a to 3f should preferably take place in such a way that the ratio of the tube outer diameter D outside the slot regions to the tube outer diameter ⁇ 1 in the slot regions is between approximately 1.02 and approximately 1.5.
- the introduction of the slots 3a to 3f can be influenced or facilitated by the fact that the collecting tube 1 is previously heat-treated at the points in question or that the tube wall is mechanically weakened at these points.
- the slots can also be made by internal high-pressure stamping.
- the collecting tube 1 has a relatively large wall thickness s in relation to its diameter D, so that it is also suitable for applications with high pressure loads.
- the manifold 1 is therefore particularly suitable for heat exchangers, such as evaporators and gas coolers, of C0 2 air conditioning systems, which are increasingly intended for use in motor vehicles.
- the tube wall thickness s is typically greater than 1.0 mm and is preferably in the range between approximately 1.3 mm and 2.5 mm. Based on the pipe outer diameter D or the pipe radius D / 2, it proves to be advantageous if the ratio D / 2s of pipe radius D / 2 to pipe wall thickness s is kept less than five and is preferably between about two and about five.
- the choice of a material for the manifold with a material hardness between about 35H V and about 80 ⁇ L has proven to be favorable, in particular for use in a heat exchanger of a C0 2 air conditioning system.
- Associated flat tube ends in particular flat tube ends twisted by 90 °, can be inserted into the slots 3a to 3f and connected gas-tight.
- the slots 3a to 3f can be provided with suitable pipe insertion bevels, which facilitates the achievement of a gas-tight connection by a subsequent sealing soldering process.
- the collecting tube can be solder-clad, or suitable shaped solder parts are used.
- the previous plating of the header pipe can be carried out by a common plating method, or also by a CD process or by galvanizing.
- the slots made in the collecting tube can also be made in the collecting tube without an inward pull-through area and without an inclined entry.
- a more or less pronounced, continuous deformation is formed parallel to the pipe extension, which due to its trough shape when sealing the flat pipe ends inserted into the slots 3a to 3f, the solder in the area to be soldered holds.
- the soldering of the flat tube ends used can be carried out in a single soldering process in which the entire structure, for example a tube / fin block structure, of the associated heat exchanger is soldered together.
- This manufacturing method can be used to manufacture flat tube condensers or gas coolers as well as evaporators of various types, for example those with a block of straight or serpentine bent flat tubes. Suitable manifolds of the type in question are then arranged on the side of the block for distributing the refrigerant of the air conditioning system to the flat tubes and for collecting the same from the flat tubes.
- the manifold 1 can be manufactured as an initially unplated manifold blank by pulling and subsequent optional plating. Another manufacturing method is illustrated in FIGS. 3 and 4. With this type of production the flat tube 1 is made of a flat material 5, which can already be solder-plated if desired. The flat piece 5, as illustrated by bending arrows B in FIG. 3, is bent parallel to its longitudinal axis 5a to form a round tube blank, as shown in FIG. 4. As can further be seen from FIG. 4, the two former flat longitudinal sides 7a, 7b lie opposite one another in the round tube blank .6, forming a narrow longitudinal gap 8. The longitudinal gap 8 is then closed gas-tight in a subsequent manufacturing step by welding or soldering.
- the sealing of the longitudinal gap 8 is carried out with flux in a separate soldering process or in a common operation together with the sealing soldering of flat tube ends, which are inserted into slots of the blank 6, which acts as a collecting tube in the finished state.
- a single complete soldering process can be provided, in which the soldered connections as well as all other soldered connections of the components required for the construction of a corresponding heat exchanger are produced.
- the push-through slots for the flat tube ends can already be inserted into the flat piece 5 or only into the round tube blank 6 before or after the gas-tight closing of the longitudinal gap 8.
- the row of slots, as shown in FIG. 1, is preferably located diametrically opposite the longitudinal gap 8.
- the elongated slots required for inserting flat tube ends can also be introduced in a different manner, for example as eccentric slots that are laterally offset from the longitudinal center plane or surface line of the collecting tube are incorporated, or as inclined slits which are inclined at an angle of more than 0 ° and less than 90 ° to telline Rohrman ⁇ or longitudinal center plane of the collection tube, a ⁇ are accommodated.
- eccentric slots that are laterally offset from the longitudinal center plane or surface line of the collecting tube are incorporated, or as inclined slits which are inclined at an angle of more than 0 ° and less than 90 ° to telline Rohrman ⁇ or longitudinal center plane of the collection tube, a ⁇ are accommodated.
- the pipe ends in this way do not open transversely to the longitudinal direction of the pipe, but instead parallel or inclined to the collecting pipe, its inside diameter can are kept smaller than the flat tube width. This favors the pressure stability of the header pipe and allows a reduction in volume of the header pipe and thus the amount of refrigerant required
- FIG. 5 Another variant is shown in FIG. 5.
- two slots 11a, 11b which are adjacent in the circumferential direction are provided, which unite to form a corresponding double slot by touching one another along the tube jacket line 10 along the side.
- Two closely spaced flat tube ends can be inserted gas-tight in this double slot.
- a row of slots similar to that of FIG. 1 can be provided, in which the slots are not spaced apart from one another, but abut with their narrow sides.
- header pipe cross sections are also possible depending on the application, e.g. a rectangular or square, a semicircular or an oval cross section.
- the manifold according to the invention is not only a single-chamber pipe, i.e. with a single distribution or collection room, but also possible as a multi-chamber pipe.
- 6 shows, as an example, a two-chamber tube 12 which contains two longitudinal channels 13a, 13b which are separate from one another. Two adjacent rows of slots 14, 15 are introduced into the two-chamber tube 12, each row of slots being designed according to that of FIG. 1 or one of the variants mentioned above and opening into one of the two longitudinal channels 13a, 13b.
- a collecting pipe can be provided, the pipe interior of which is divided by one or more transverse dividing walls into a plurality of collecting rooms which follow one another in the longitudinal direction of the pipe, into each of which one or several flat tube ends open, which are tightly inserted in the associated header tube slots.
