Definitions
- the invention relates to a collector of a heat exchanger according to the preamble of claim 1.
- collector should generally not only be understood to mean an intermediate collector or collector on the outlet side, but also an distributor on the inlet side.
- a lid, a tube sheet or a compartment division has generally been made from sheet metal or plate-shaped material, with the lid being deep-drawn, for example, from sheet metal.
- Injection molded parts have also been used for special constructions.
- a sandwich construction made of injection-molded plates was used for an evaporator, which is also to be used in particular for automotive air conditioning systems, in which the chambers required for the distributor were obtained by appropriate groove designs.
- die-casting is used in the description of the invention instead of the term injection molding, although within the scope of the invention the terms die-casting and injection molding are considered synonymous.
- the invention has for its object to make the possibilities of die casting for collectors in heat exchangers for motor vehicles even more useful than was previously considered.
- the invention thus advantageously enables a combination of the following two aspects which has not previously been considered:
- the use is included in the soldering, in particular hard soldering, of the entire collector.
- the spatial design options for manufacturing the collector from die-cast are made available.
- Die-casting production is not limited to a plate construction, but can also be used for the production of tub-like bodies with a bottom and surrounding side wall. Such a circumferential side wall is in the known plate construction of not available in advance.
- Die-casting technology also makes it possible to manufacture filigree flat grids, which up to now have been produced in a complicated assembly construction from cut sheet metal strips (cf. DE 195 15 526 Cl, Fig. 11).
- the invention focuses on one of the above three aspects and includes the remaining two further aspects as further developments of the invention.
- the invention provides die-cast parts for use and preferably also for the jacket (cf. claim 12), which in many respects correspond in shape to the preformed sheet metal parts.
- the invention also contemplates combining die cast parts with sheet metal parts.
- shaped sheet metal parts have usually been soldered using braze.
- This conventional type of connection by soldering, in particular by brazing, is adopted in the context of the invention with the full or partial inclusion of die-cast parts by using a solderable alloy as the material for the die-cast part in question.
- the pin according to claim 2 (with the further developments of claims 3 to 10 and 14) have the advantage, inter alia, of being able to carry out a mechanically coherent preassembly of the cover and tube plate of the collector before soldering the collector so that the soldering gap is minimal remain and accordingly the security against leaks when soldering is maximum.
- Figure 1 is an external perspective view of a four-pipe flat tube heat exchanger designed as an evaporator.
- FIG. 2 shows a possible cross-sectional configuration of the flat tube heat exchanger according to FIG. 1 with a first variant. ante the training of the collector;
- FIG. 3 shows a cross section corresponding to FIG. 2, but with a second variant of the design of the collector
- Fig. 4 shows a possible die-cast compartment subdivision of the collector according to Fig 3, which can be used between the tube sheet and the lid.
- FIG. 5 shows a plan view of the tube plate of a collector according to FIG. 3 with the cover removed but with the compartment subdivision attached according to FIG. 4;
- 6a to 6d detail cross-sections of four variants each of a connection point of the compartment subdivision according to FIG. 4 with the tube sheet or the cover of the evaporator according to FIG. 3;
- Fig. 7 shows a section along a die-cast cover of an inlet-side collector.
- the flat tube heat exchanger shown in the figures is of four-pipe design in all the exemplary embodiments shown and is designed as an evaporator of a refrigerant circuit.
- the flat tube heat exchanger has the following general structure:
- a larger number of typically twenty to thirty flat tubes 2 are arranged with constant mutual distances and mutually aligned end faces 4.
- a zigzag lamella 8 is sandwiched between the flat sides 6 of the flat tubes.
- a zigzag fin 8 is also arranged on the two outer surfaces 4 of the outer flat tubes.
- Each flat tube has inner stiffening webs 10 which are in the Divide the flat tube into chambers 12 acting as continuous channels. Depending on the overall depth, a number of chambers 12 of ten to thirty is typical.
- the block arrangement of the flat tubes 2 and the zigzag fins 8 is flowed through by outside air in the direction of the arrow shown in FIG. 1 in the depth direction as the external heat exchange medium in the finished state.
- the internal heat exchange medium in the evaporator is a refrigerant such as, in particular, fluorocarbon, which enters the heat exchanger via a feed line 14 and exits the heat exchanger via an outlet line 16.
- the supply line comes from the condenser in the refrigerant circuit.
- the output line 16 leads to the compressor of the refrigerant circuit.
- the refrigerant on the inlet side is distributed from the feed line 14 to the individual flat tubes by a so-called distributor.
- the refrigerant is fed collectively to the output line 16. If the distribution and the collection can also be assigned to separate boxes, both functions are combined in a common collector 18 in all exemplary embodiments.
- This collector 18 is then arranged on one end face 4 of the flat tubes 2, while on the other end face 4 of the flat tubes 2 there is only a reversal of the flow between the floods, here, for example, by means of the individual cups 20 depicted in FIG. 1 or according to the depiction in FIG 2 integrating the deflection functions of such individual bowls in a common deflection collector 22.
- the individual bowls 20 according to FIG. 1 can also if necessary, be integrated into a structural unit by connecting parts, not shown.
- cups 20 or the deflection collector 22 would be replaced by an output collector (not shown).
- the multiple flow means at least one flow reversal in the area of the individual channels formed by the chambers 12 in each flat tube 2.
- the cup 20 or the deflection collector 22 does not need any further sub-chamber division, but only the one-time deflection function must be guaranteed.
- at least the intermediate wall 24 shown in the case of the four-flow arrangement in FIG. 2 is required, so that in this case of the four-flow arrangement, a double simple deflection takes place in the respective bowl 20 or in the respective deflection collector 22. If the number of floods is even higher, the number of partitions 24 may then have to be increased.
- the collector 18 is basically composed of a tube sheet 26 and a cover 28, it being possible, if necessary, to provide further parts for the construction of the collector 18, which are at least partially specified below.
- the collector 18 Since the input function and the output function of the refrigerant are combined in the collector 18, the collector 18 requires at least a two-chamber design which separates an input side from the output side.
- the chamber subdivision, generally designated 30, has at least one flat web in the form of a longitudinal web 32 which separates the input area in the collector 18 communicating with the feed line 14 from an outlet chamber 34 which runs continuously along the collector 18 and which communicates with the output line 16.
- the inlet-side refrigerant In the evaporator, it is also necessary for the inlet-side refrigerant to be fed as uniformly as possible to all flat tubes 2.
- the supplied refrigerant can be fed separately to each individual flat tube 2 via a so-called distributor.
- the feed takes place to neighboring groups of flat tubes in which at least some groups have a higher number of flat tubes than one, and the number of flat tubes per group can also change.
- an equal number of two flat tubes per group is provided with a total of ten flat tubes.
- An inlet chamber 36 is assigned to each group of flat tubes, which communicates directly with the relevant group of flat tubes.
- the inlet chambers 36 are separated from one another in the chamber subdivision 30 by transverse webs 38 designed as flat webs.
- the transverse webs 38 only extend from one side of the longitudinal web 32 at right angles.
- a further longitudinal web 40 parallel to this is provided in addition to the longitudinal web 32 which adjoins the outlet chamber 34. This is crossed by the transverse webs dividing the inlet chambers 36 at right angles to the longitudinal web 32.
- an inner deflection chamber 42 adjoining the respective outer inlet chamber 36 is provided between these longitudinal webs for deflecting the second flood into the third flood within the Collector 18 divided.
- the number of longitudinal webs with the function of the longitudinal web 40 increases as well as the number of inner deflection chambers 42, which then also lie side by side between the inside in the transverse direction of the collector Entry chambers 36 and the exit chamber 34 are nested.
- the feed line 14 communicates with the individual inlet chambers 36 in each case via its own feed line 44 running in the collector 18, which is designed differently in the exemplary embodiments.
- the block of flat tubes 2 and zigzag fins 8 is laterally closed off by a side plate 46 which bears against the outer zigzag plate, so that the side plates 46 form an outer frame for the outside air flowing into the heat exchanger block.
- the flat tubes 2, the zigzag fins 8, the tube sheet 26 and the cover 28 of the collector together with the optionally provided chamber division 10 and the side plates 46 of the heat exchanger are expediently made of aluminum and / or an aluminum alloy and the same as the feed line 14 and the outlet line 16 are brazed including the sections of the line connections to the finished evaporator adjacent to the heat exchanger.
- the tube sheet 26 and the cover 28 are formed from sheet metal pre-coated with solder.
- the free edge of the cover engages in the tube sheet 26 with at least one-sided overlap - a two-sided overlap 52 is shown in FIG. 3.
- the own supply lines 44 of the inlet chambers 36 are integrated in a distribution pipe 54, which has a pipe jacket 56 and an inner star-shaped subdivision 58, the free segments of which form the own supply lines 44.
- the star-shaped subdivision 58 extends in a helical or helical shape.
- the respective own supply line 44 communicates with the associated inlet chamber 36 via an outlet opening 60 arranged in the tubular jacket 56 of the distribution pipe 54.
- the respective outlet openings 60 can also be designed throttle-like for direct injection purposes into the inlet chamber and dimensioned such that the pressure drop between the liquefaction and evaporation pressure is substantially reduced.
- 3 shows an alignment of the outlet opening on the wall of the inlet chamber 36; the appropriate angle can be selected as required, without a direct alignment to the chambers 12 of the flat tubes 2 being excluded.
- the chamber subdivision 30 consists of the two longitudinal webs 32 and 40 and the cross webs 38 crossing them on an integral die-cast or injection-molded part, the terms die-cast and injection-molding being synonymous within the scope of the invention be understood.
- intersecting flat webs of the chamber subdivision 30 should also be understood to mean the borderline case of only one-sided crossing in the sense of the only one-sided right-angled connection of the transverse webs 38 to the longitudinal web 32, which in the case of a double-flow heat exchanger makes up the entire chamber subdivision 30.
- connection points of the longitudinal webs 32 and 40 with the flat webs 38 are each provided with a columnar reinforcement 62 which tapers conically outwards on both opposite sides of the chamber subdivision 30 Pass over pins 64 which are aligned on both sides of the chamber subdivision with one another and with the columnar reinforcements 62.
- These pins 64 are integrally formed on the die-casting of the chamber subdivision 30 and are used for connection to both the tube sheet 26 and the cover 28, a connection type being illustrated in FIG. 3, namely that of FIG. 6c, which will be described below.
- FIG. 5 shows a variant of the embodiment according to FIG. 4, where, in addition to the pins 64 on both sides, between these pins 66, which are additional on both sides, are formed in a uniform grid-shaped interposition between the pins 64, which may also consist of columnar reinforcements 62 the flat webs can emerge, which are then not formed at intersections of the flat webs.
- the grid of the pins 64 and 66 is selected such that it is nested in the grid of the connection points of the flat tubes 2, so that it does not mechanically lead to an unfavorable interaction of the pin connections of the chamber partition 30 the tube sheet on the one hand and the flat tubes 2 with the Rohrêt on the other hand comes.
- An eccentric nesting is shown, but it can also be provided in the center.
- 6a to 6d show four preferred types of connection of the pins with the sheet metal of the tube sheet 26 and / or the cover 28 without intending to provide a final list.
- the sheet only needs to be stamped like a cup, in which case the pin 64 or 66 in question engages with the conical end thereof and is brazed there.
- This connection method would take over the type of connection of the flat webs, in particular the longitudinal webs 32 and 40, the chamber subdivision 30 with the cover 28 and / or the tube plate 26.
- FIG. 6a shows a simple implementation, which in turn is brazed.
- FIG. 6c the pin carried out is upset on the outside according to FIG. 1, so that it forms an external, form-fitting undercutting lock.
- the spigot which is of equal thickness in the other embodiments, with the exception of the conical bevel, is additionally thickened in a column-shaped manner so that an undercut occurs on the inside of the header 18, which in connection with the upsetting in the sense 6c causes a complete encompassing of the sheet metal from the tube sheet and cover.
- the cup-like shape of FIG. 6a is also adopted in the embodiments according to FIGS. 6b to 6d, but in addition a penetration hole is present in this cup-shaped shape. This increases the dimensional stability of the sheet metal structure.
- the transverse webs 38 are each provided with an approximately semicircular recess 70 in which the distribution tube 54 according to FIG. 3 is inserted. If it is made of hard-solderable aluminum or a corresponding aluminum alloy, then the distribution pipe can be soldered in the manner described with the entire heat exchanger.
- FIG. 2 corresponds to the embodiment according to FIGS. 3 and 4 with the exception that the distribution pipe 54 and the recesses 70 matched to it are dispensed with. Instead, the own supply lines 44 to the individual inlet chambers 36 are additionally formed integrally in addition to the pressure casting of the chamber subdivision 30 in this pressure casting.
- the collector 18 has two levels when viewed in the direction of extension of the flat tubes.
- all of the inlet chambers 36 mentioned are arranged in the groups of flat tubes.
- In the upper level there are additional feed lines 44 to the chambers 36.
- the formation of this area in an integral die-cast piece is easily possible because in the die-cast piece the inlet chambers 36 are still open to the long side of the collector 18 and the own feed lines 44 on the are open to the side facing away from the flat tubes 2 and are separated from the inlet chambers 36 only by an intermediate wall 72 separating the two levels, in each of which the outlet openings 60 are arranged, the dimensioning of which is the same as stated with regard to the distributor tube 54.
- the own feed lines 44 of the inlet chambers 36 upstream are jointly fed by the inlet-side refrigerant, as is also the case with respect to the distribution pipe 54.
- the own supply lines 44 are each terminated at their end, as is the same for the free end of the distribution pipe 54.
- At least the chamber subdivision and optionally the distribution device of the inlet-side refrigerant to the individual inlet chambers are integrated in a die-cast part.
- this can be inserted as a separate part in a tube sheet 26 and cover 28 of the collector 18 formed from sheet metal, the cover and the bottom also forming the peripheral surface of the collector 18 entirely or predominantly.
- the cover and / or the tube sheet can each be an integral die-cast part. This is described with reference to FIG. 7, in the embodiment of which at least the cover 28, which is only considered below, is itself made of die-cast.
- the tube sheet can advantageously be formed from solder-coated sheet metal, as in the previously described designs, but, as mentioned, can also be an integral die-cast piece in a manner not described in detail.
- the embodiment according to FIG. 9 is not intended to exclude the possibility described with reference to FIGS. 1 to 6b to manufacture the chamber subdivision 30 as a separate die-cast piece, which is inserted into a cover 28, which is likewise made on the die-cast part, and optionally also on a die-cast part manufactured tube sheet 26 is placed together with the cover 28.
- the own supply lines 44 can also be arranged in a separate distribution pipe 54 according to FIG. installed as a separate component in the collector and e.g. 4 is placed on the semicircular recesses 70 of the chamber partition 30.
- the cover 28, tube sheet 26, chamber partition 30 and distributor tube 54 can be separate components.
- cover 28 as a die-cast part can e.g. transferred to the variant according to FIG. 2, where the own feed lines 44 are arranged only in the area of the inlet chambers 36 and can be integrated in the cover if necessary. In the borderline case, however, the own supply lines 44 can extend as far as the longitudinal web 32 adjoining the outlet chamber 34 and, if necessary, can be integrated in the die-cast part of the cover 28.
- supply line 14 and output line 16 are arranged on the end face of the collector 18 or on its cover 28, as in FIG. 1.
- an arrangement of the output line 16 on the long side of the collector, in particular at the center thereof, can also be provided.
- FIG. 7 shows an embodiment of the cover 28 in which the fluid distribution over the individual gene supply lines 44 to the inlet chambers 36 is designed in a preferred manner.
- a thermostatically controlled injection valve 86 is partly included in the design of the cover 28 as a die-cast part and thus, with its essential component outside of the evaporator, no longer takes up its own installation space, as is still the case with the design as a block valve 50 in FIG. 1 .
- the housing 88 of the injection valve 86 is also formed from the die-cast part of the cover 28.
- a threaded bore 90 is recessed, which is obtained in post-processing by unscrewing and into which an adjusting screw 94 can be screwed in to different degrees under circumferential sealing by means of an O-ring seal 92.
- This adjusting screw 94 forms, with a cavity formed on its inner end face, a receiving space for the valve spring 96, which is held on its inner side by a valve cage 98, which carries a spherical valve element 100 on its end face facing away from the valve spring, which cooperates with a valve seat 102 .
- valve element is biased by the valve spring 96 in the closed position of the valve opening 104 surrounded by the valve seat and controls the cross-section of the connection between the feed line 14 and a mixing space 106 which is arranged upstream of the feed openings 44 to the inlet chambers 36.
- a guide extension 108 is also formed in the die-cast part, which protrudes obliquely into the mixing space 106 and has a distribution function on the individual feed lines 44.
- a baffle function is also taken over by the throttle function on the injection valve.
- Axial of the threaded bore 90 is in the Die-cast part recessed a further threaded bore 110 for receiving the thermal head 112, which communicates with the outlet chamber 34.
- the thermal head is connected to the spherical valve element 100 via a stepped valve pin 114, the valve pin having play in relation to the inner opening of the threaded bore 110, so that the flow connection between the outlet chamber 34 and the thermal head remains guaranteed.
- the injection valve is opened more or less, so that an adjustment to a constant temperature determined by the screwing depth of the adjusting screw 94 is established.
- the supply line 14 and the output line 16 have a common connecting flange 116 which engages in bag-shaped threaded bores 120 on the outside of the die-casting by means of fastening screws 118.
