Description

144594 i o144594 in o

Opfindelsen angår en fremgangsmåde til fremstilling af et til varmevekslere bestemt rør af den i patentkravets indladning angivne art.The invention relates to a method for producing a tube for heat exchangers of the kind specified in the patent claim.

Sådanne rør kendes fra beskrivelsen til DK-FS nr.Such pipes are known from the description of DK-FS no.

5 136916. De således kendte rør er - jfr. nævnte skrifts fig. 3 og 4 - udformet således med stavene bukket i forskellig grad, at der opnås forskellige urunde omskrivningsflader for rørene med de derpå anbragte stave. På denne måde kan rørene med stavene anbringes tæt sammen uden mellem-10 liggende fyldlegemer eller skillevægge - se navnlig fig. 3.5 136916. The tubes thus known are - cf. FIG. 3 and 4 - designed with the rods bent to varying degrees to obtain different rounded rewrite surfaces for the tubes with the rods placed thereon. In this way, the tubes with the rods can be placed close together without intermediate filler bodies or partitions - see in particular fig. Third

Som det vil kunne ses af DK-FS nr. 136916, svarer de forskellige urunde omskrivningsflader til kappeflader i geometriske legemer, som ikke er af sådan form, at de kan stables sammen i hovedsagen uden mellemrum, således som 15 det f.eks. er tilfældet med regulære sekskantede prismer, der som bekendt kan stables sammen i et såkaldt bikagemønster.As can be seen from DK-FS No. 136916, the various rounded rewrite surfaces correspond to sheath surfaces in geometric bodies which are not of such shape that they can be stacked together in the main case without spaces, such as e.g. is the case with regular hexagonal prisms that, as you know, can be stacked together in a so-called honeycomb pattern.

Opfindelsen adskiller sig fra det således kendte ved den i patentkravets kendetegnende del angivne fremgangsmåde. Herved opnås, at rørene kan anvendes til varmevekslere af 20 vilkårlig størrelse, idet det blot er nødvendigt at stable eller bundte rørene sammen i det ønskede antal, og de i DK-FS nr. 136 916 omtalte fordele, blandt andet med hensyn til forøget turbulens, bibeholdes uændret. Desuden opnås væsentlig forenkling af fremstillingen i forhold til 25 enkelvis eller gruppevis bukning af stavene, og udformningen af rørene ved fremgangsmåden medfører tillige, at der kan anvendes en og samme trækkedyse til samtlige rør i én type varmeveksler - eller i flere typer med samme omskrivningsflade for rørene.The invention differs from the method thus known in the characterizing part of the claim. This provides that the pipes can be used for heat exchangers of any size, since it is only necessary to stack or bundle the pipes together in the desired number, and the advantages mentioned in DK-FS No. 136,916, among other things with regard to increased turbulence. , remains unchanged. In addition, substantial simplification of the manufacture is achieved in relation to single or group bending of the rods, and the design of the pipes by the method also means that one and the same drawing nozzle can be used for all pipes in one type of heat exchanger - or in several types with the same paring surface for pipes.

30 Opfindelsen vil i det følgende blive nærmere forklaret under henvisning til tegningen, der viser et udførelseseksempel, og på hvilken fig. 1 viser et længdesnit gennem en rørvarmeveksler med overfladeforøgende elementer, der er bukket ifølge 35 opfindelsen, fig. 2 et snit efter linien II-II i fig. 1, fig. 3 i større målestok et snit gennem et enkelt rør med overfladeforøgende elementer, bukket ifølge opfindelsen, 3The invention will now be explained in more detail with reference to the accompanying drawings, in which: FIG. 1 is a longitudinal section through a tube heat exchanger with surface-increasing elements bent in accordance with the invention; FIG. 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is an enlarged section through a single tube with surface-increasing elements bent in accordance with the invention; 3

Den i fig. 1 viste varmeveksler har en kappe 1 med tilslutninger 2, 3, 4 og 5 for tilførsel og bortledning 10 af et første (2,3) respektive et andet (4,5) strømmende medium. I en nær ved varmevekslerens ene ende anbragt plade 6 er fastgjort et antal rør 7, som forløber parallelt med varmevekslerens akse. Koncentrisk omkring rørene 7 er yderligere rør 8 anbragt, som er fastgjort i en med pladen 6 parallel 15 plade 9. Rørene 8 er lukket i deres bort fra fastgørelsen vendende ende, og rørene 7 strækker sig i det væsentlige helt igennem rørene 8 og udmunder i nærheden af disses lukkede ender. Det andet medium kan således strømme fra tilførselstilslutningen 4, parallelt gennem rørene 7 ned i 20 rørene 8, op gennem rørene 8 uden for rørene 7, ud i mellemrummet mellem pladerne 6 og 9 og endelig ud gennem tilslutningen 5. Det første medium strømmer på simpel måde ind gennem tilslutningen 2, op omkring rørene 8 og ud gennem tilslutningen 3.The FIG. 1 has a sheath 1 with connections 2, 3, 4 and 5 for supply and discharge 10 of a first (2,3) and a second (4,5) flowing medium, respectively. At a plate 6 located near one end of the heat exchanger is attached a plurality of tubes 7 which extend parallel to the axis of the heat exchanger. Concentrically around the pipes 7, further pipes 8 are arranged which are fixed in a plate 9 parallel to the plate 6. The pipes 8 are closed at their end away from the attachment, and the pipes 7 extend substantially all the way through the pipes 8 and open into the pipes. The proximity of their closed ends. Thus, the second medium can flow from the supply connection 4, parallel through the pipes 7 down into the pipes 8, up through the pipes 8 outside the pipes 7, out into the space between the plates 6 and 9 and finally out through the connection 5. The first medium flows in a simple manner. way in through connection 2, up around pipes 8 and out through connection 3.

25 Rørene 8's yderside er forsynet med tæt ved hinan den placerede, overfladeforøgende tappe 10, som er i hovedsagen vinkelret indsat i rørvæggene 1. Som vist i fig. 3 og 4 er imidlertid hver enkelt tap 10 bukket ned mod det tilhørende rør 8 til en i forhold til den pågældende rørydervæg 30 således afpasset individuel afstand, at hvert rørtværsnit, som det især fremgår af fig. 3, kan omskrives af en regulær sekskant. I det her omtalte udførelseseksempel indebærer dette, at tappene ved sekskantens hjørner er ubukkede, mens tappene ved midten af sekskantens sider er stærkest bukket. Denne buk-35 ning af tappene medfører, at rørene 8 kan anbringes i bikagemønster, som det fremgår af fig. 2, hvad der dels indebærer, at rø-The outer surface of the pipes 8 is provided with adjacent to each other the surface-increasing pin 10, which is generally perpendicularly inserted into the pipe walls 1. As shown in FIG. 3 and 4, however, each pin 10 is bent down against the associated pipe 8 to an individual distance so adapted to the respective pipe riser wall 30 that each pipe cross-section, as can be seen in particular in FIG. 3, can be rewritten by a regular hexagon. In the embodiment described herein, this means that the pins at the corners of the hexagon are unbuckled, while the pins at the center of the sides of the hexagon are strongly bent. This bending of the pins means that the tubes 8 can be placed in honeycomb pattern, as can be seen in FIG. 2, which in part implies that

3 f44594 rene kan placeres på en meget pladsbesparende måde, dels, at der kun behøves fyldelegemer mellem de yderste rør og kappens væg.3 f44594 cleans can be placed in a very space-saving way, partly that only filler bodies are needed between the outer tubes and the casing wall.

I den i fig. 5-8 viste varmeveksler indføres det 5 første medium gennem en tilslutning 2 i varmevekslerens ene ende, og det udtages gennem en tilslutning 3 i dens anden ende, hvori der ligeledes er anbragt en tilslutning 4 for tilførsel af det andet medium. Pra tilsituningen 4 strømmer det andet medium til et fordelerhus 20, hvorfra det fordeles 10 til et antal, i dette tilfælde tre, rækker rør 13, 14 og 15, af hvilke rækkerne 13 og 14 direkte modtager det andet medium i deres mod fordelerhuset vendende ende, mens en diametral række rør 15 er forsynet med indvendige rør 7, der på lignende måde som ovenfor beskrevet leder det andet medium 15 ned til rørene 151 s bund for derpå at lade det strømme op langs rørene 7. Hvert enkelt rør 13 og 14 står i sin bort fra fordelerhuset 20 vendende ende gennem rør 16 i forbindelse med to yderligere rækker rør 17 og 18, som leder det andet medium hen til et samlehus 19 ved samme ende af varmeveksle-20 ren som fordelerhuset 20. I forbindelse med samlehuset 19 står også den tilsvarende ende af den diametralt anbragte rørrække 15, så at også den i disse rør strømmende del af det andet medium når samlehuset 19 og kan strømme ud gennem tilslutningen 5.In the embodiment shown in FIG. 5-8, the first medium is introduced through a connection 2 at one end of the heat exchanger and it is taken out through a connection 3 at its other end, in which is also provided a connection 4 for supplying the second medium. At junction 4, the second medium flows to a distributor housing 20, from which it is distributed 10 to a plurality of, in this case three, rows of pipes 13, 14 and 15, of which rows 13 and 14 directly receive the second medium at their end facing the distributor housing. whereas a diametrical row of tubes 15 is provided with inner tubes 7 which, in a similar manner as described above, guide the second medium 15 down to the bottom of tubes 151 and then allow it to flow up along tubes 7. Each tubes 13 and 14 stand in its away from the distributor housing 20 facing end through pipes 16 in conjunction with two further rows of pipes 17 and 18, which direct the second medium to a collector housing 19 at the same end of the heat exchanger 20 as the distributor housing 20. In connection with the collector housing 19 stands also the corresponding end of the diametrically arranged pipe row 15, so that the portion of the second medium flowing in these pipes also reaches the assembly housing 19 and can flow out through the connection 5.

25 En væsentlig fordel ud over de allerede omtalte ligger i, at det ikke er nødvendigt med styre- eller lederør omkring de med tappe forsynede rør, og rørpladen kan således helt undværes, som det er vist i fig. 5, eller blot indsættes i varmevekslerens ene ende, som fig. 1 viser det.A significant advantage over the aforementioned is that no guide or guide pipes are needed around the tapped pipes, and the tube plate can thus be completely avoided, as shown in FIG. 5, or simply inserted into one end of the heat exchanger, as FIG. 1 shows it.

30 Dette betyder igen, at rørene kan forsynes med overfladeforøgende elementer tilnærmelsesvis over hele deres længde, hvorved varmeveksleren kan gøres kortere.This in turn means that the pipes can be provided with surface-increasing elements approximately their entire length, thereby reducing the heat exchanger.
