Description
Oppfinnelsen angår en konvektor ifølge innledningen til patentkrav 1. The invention relates to a convector according to the introduction to patent claim 1.
Ved tidligere kjente konvektorer av den angitte art er platelamellene fast anbragt på røret ved lodding e.l., for å skaffe god kontakt mellom dette og lamellene for å overføre varme til eller fra den omgivende luft. In the case of previously known convectors of the type indicated, the plate slats are firmly placed on the tube by soldering or the like, in order to provide good contact between this and the slats in order to transfer heat to or from the surrounding air.
Véd tidligere kjente konventorer av nevnte art danner røret og platelamellene en fast enhet, hvilket medfører at røret i sine to ender må kobles til det rørsystem som er bestemt for varme- eller kjølemedium med skjøtemuffer e.l. Nevnte fremgangsmåte innebærer meget manuelt arbeide, hvilket medfører høye omkostninger og for-holdsvis lang arbeidstid. With previously known convectors of the aforementioned type, the tube and the plate slats form a fixed unit, which means that the tube must be connected at its two ends to the tube system that is intended for heating or cooling medium with joint sleeves etc. Said method involves a lot of manual work, which entails high costs and relatively long working hours.
Da det fra et arbeidsteknisk synspunkt ofte er fordelaktig først Since, from a work-technical point of view, it is often advantageous first
å montere og gjøre ferdig selve rørsystemet som en enhet, har det lenge foreligget behov for etter monteringen hurtig og effektivt å kunne montere "pakker" (grupper) av lameller på passende steder i rørsystemet. Ved hjelp av hittil kjente konvektorer har dette imidlertid ikke vært mulig å gjennomføre. to assemble and finish the pipe system itself as a unit, there has long been a need to be able to quickly and efficiently assemble "packs" (groups) of lamellas at suitable places in the pipe system after assembly. With the help of hitherto known convectors, however, this has not been possible.
Blant annet fra søkerens norske utlegningsskrift nr. 129.109 er Among other things from the applicant's Norwegian interpretation document no. 129.109 is
det kjent en konvektor hvor lamellene er vinkelrett innfestet i to motstående, parallelle og langstrakte sidestykker av plate, hvor hver lamell er utformet med en krage som spennes mot røret. Disse krager kan imidlertid ikke alltid bringes til å ligge an mot røret med tilstrekkelig stor kraft. a convector is known where the slats are perpendicularly fixed in two opposite, parallel and elongated side pieces of plate, where each slat is designed with a collar that is clamped against the tube. However, these collars cannot always be made to rest against the pipe with sufficient force.
Vedohjelp av konvektoren ifølge foreliggende oppfinnelse fylles nevnte behov på en særdeles effektiv og formålstjenlig måte. Det oppnås hovedsakelig ved å utforme konvektoren i overensstemmelse med patentkrav 1. With the help of the convector according to the present invention, said needs are met in a particularly efficient and expedient manner. It is mainly achieved by designing the convector in accordance with patent claim 1.
Det skal understrekes særlig at lamellenes sfæriske form gjør dem enklere å anbringe på røret. Ved at de overspennes i motsatt retning kommer lamellene til å ligge tett an mot røret med spennvirkning, hvilket forårsaker at varmeovergangen blir betydelig mer effektiv enn hva som tidligere har vært mulig. It should be emphasized in particular that the spherical shape of the slats makes them easier to attach to the pipe. By overstressing them in the opposite direction, the slats come to lie close to the tube with a tension effect, which causes the heat transfer to become significantly more efficient than what has previously been possible.
En utførelsesform for konvektoren ifølge oppfinnelsen er beskrevet nærmere i det følgende i tilknytning til tegningene. Fig. 1 viser et perspektivriss av lamellpakken, nedpresset over et rør som inngår i et rørsystem. Fig. 2 viser, i større målestokk, et perspektivriss av en i lamellpakken inngående sfærisk bøyd lamell. Fig. 3 viser et snitt gjennom samme lamell etter linjen A-A i fig. 2. Fig. 4 viser i perspektiv lamellenes innfestning i de to motstående sidestykker. Fig. 5 viser, i snitt og i større målestokk, en del av en sfærisk bøyd lamell og et rør, som omgis av lamellens krage, uten at denne spennes mot røret. Fig. 6 viser samme riss, der en sfærisk bøyd lamell ved kraftpåvirk-ning er bøyd sfærisk i motsatt retning slik at lamellens krage ligger spennvirkende an mot røret. Fig. 7 anskueliggjør i perspektiv en fremgangsmåte til å presse ned lamellpakken over røret, idet et mothold anbringes mot røret, mens et presstrykk (pilen) anbringes mot lamellpakken. Fig. 8 viser, i større målestokk, et perspektivriss av en del av lamellpakken og et rør, der et trykkvirkende forankringsorgan for lamellenes bøyning er anordnet ved pakkens ene ende. Fig. 9 viser ovenfra et enderiss av lamellpakken og røret med det trykkvirkende forankringsorgan. An embodiment of the convector according to the invention is described in more detail below in connection with the drawings. Fig. 1 shows a perspective view of the lamella pack, pressed down over a pipe that is part of a pipe system. Fig. 2 shows, on a larger scale, a perspective view of a spherically bent lamella included in the lamella package. Fig. 3 shows a section through the same lamella along the line A-A in fig. 2. Fig. 4 shows in perspective the attachment of the slats in the two opposite side pieces. Fig. 5 shows, in section and on a larger scale, part of a spherically bent lamella and a tube, which is surrounded by the collar of the lamella, without this being clamped against the tube. Fig. 6 shows the same drawing, where a spherically bent lamella is bent spherically in the opposite direction under the influence of force so that the collar of the lamella rests against the pipe in a tensioning manner. Fig. 7 shows in perspective a method for pressing down the lamella package over the pipe, a counter-hold being placed against the pipe, while a pressing pressure (the arrow) is placed against the lamella package. Fig. 8 shows, on a larger scale, a perspective view of part of the slat pack and a tube, where a pressure-acting anchoring means for bending the slats is arranged at one end of the pack. Fig. 9 shows from above an end view of the lamellar package and the tube with the pressure-acting anchoring device.
Med 10 på figurene angis en i lamellpakken inngående sfærisk formet platelamell av meget tynt, hensiktsmessig fjæryirkende platemateriale. Lamellen 10 er utformet med et sentralt uttak 11 og en inntil dens kant utgående krage 12,^ som er bestemt til å bringes-til å ligge an mot et, i et varme- eller kjølesystems inngående rør 13. Lamellen 10 er rektangulært eller kvadratisk formet, og ved to motstående kantpartier utformet med vinkelbøyde flenser 14, 14', som er innfestbare i to langstrakte sidestykker 15 og 15' av plate, slik at et antall, likt utformede lameller 10, With 10 in the figures, a spherically shaped plate lamella of very thin, suitable spring-acting plate material included in the lamella package is indicated. The lamella 10 is designed with a central outlet 11 and a collar 12 extending to its edge, which is intended to be brought into contact with an incoming pipe 13 of a heating or cooling system. The lamella 10 is rectangular or square shaped , and at two opposite edge parts designed with angled flanges 14, 14', which can be attached to two elongated side pieces 15 and 15' of plate, so that a number of similarly designed slats 10,
sammen med sidestykkene 15, 15' danner lamellpakken. together with the side pieces 15, 15' form the lamellar package.
Hver lamell 10 er ved sitt ene frie kantparti utformet med en åpning 16 som strekker seg frem til uttak 11, slik at samtlige i pakken inngående lameller 10 kan presses ettergivende over røret 13. Ved at hver lamell 10 er sfærisk formet og kragen 12 er anordnet på dens utadbøyde side samt at uttakets 11 og kragens 12 areal er lik med eller noe større enn rørets 13 ytre tverrsnitts-areal, spenner lamellenes 10 krager 12 ikke mot røret når lamellpakken er nedført over røret 13 ifølge fig. 5. Hver lamell 10 er på sin utadbøyde side dessuten forsynt eller utformet med et antall distanseorganer 17 og 17' av samme høyde som kragens 12 bredde. Disse distanseorganer 17, 17' kan hensiktsmessig bestå av opp-pressede utbuktninger i lamellens 10 platemateriale, idet utbukt-ningene i hver annen lamell 10 hensiktsmessig er stillingsforskjøvet i forhold til hverandre, slik at de alltid ligger an mot lamellenes 10 flater. Each slat 10 is designed at its one free edge with an opening 16 that extends to outlet 11, so that all slats 10 included in the package can be pressed yieldingly over the tube 13. As each slat 10 is spherically shaped and the collar 12 is arranged on its outwardly bent side and that the area of the outlet 11 and the collar 12 is equal to or somewhat larger than the outer cross-sectional area of the tube 13, the collars 12 of the lamellas 10 do not tension against the tube when the lamella package is lowered over the tube 13 according to fig. 5. On its outwardly bent side, each slat 10 is also provided or designed with a number of spacers 17 and 17' of the same height as the width of the collar 12. These spacers 17, 17' can suitably consist of pressed-up bulges in the plate material of the slats 10, the bulges in every other slat 10 being appropriately shifted in position relative to each other, so that they always rest against the surfaces of the slats 10.
Samtlige lameller 10 i lamellpakken, når denne er anordnet over røret 13, forskyves samtidig ved sitt midtparti ved hjelp av et trykkvirkende forankringsorgan, slik at lamellene 10 bøyes sfærisk til motsatt side, ifølge fig. 6 og 9. Dette medfører at hver la-mells 10 krage 12 automatisk minsker i areal og dermed bringes til spennvirkende og å ligge tett an mot røret 13, slik at god temperaturledning oppnås. Ved lamellenes 10 forskyvning og over-spenning, låses disse automatisk i denne stilling selv etter fjernelse av det trykkvirkende forankringsorgan. Nevnte overspen-ning av lamellene 10 kan utføres dels ved fremstillingen av pre-fabrikerte konvektorer og dels ved lamellpakkens anbringelse på All lamellas 10 in the lamella pack, when this is arranged above the pipe 13, are simultaneously displaced at their middle part by means of a pressure-acting anchoring device, so that the lamellas 10 are bent spherically to the opposite side, according to fig. 6 and 9. This means that the collar 12 of each lamella 10 automatically decreases in area and is thus brought to tension and to lie closely against the pipe 13, so that good temperature conduction is achieved. When the lamellas 10 are displaced and over-tensioned, they are automatically locked in this position even after the pressure-acting anchoring device has been removed. Said overvoltage of the slats 10 can be carried out partly during the production of prefabricated convectors and partly when the slat pack is placed on
rør i ferdig fremstilte rørsystemer til dannelse av konvektorer. Ved lamellpakkens anbringelse på rør 13 i et ferdiglaget rør-system er det i visse tilfelle hensiktsmessig å utføre et mottrykk mot røret 13 ved pakkens nedpressing over røret. Gjennom lamellenes 10 åpninger 16 og mot røret 13 kan derved innføres et mothold 18 i form av en stålskinne e.l., som kan kobles til et mot pakken pressvirkende organ (fig. 7). Ved denne fremgangsmåte er pipes in ready-made pipe systems to form convectors. When placing the lamellar pack on pipe 13 in a ready-made pipe system, it is appropriate in certain cases to exert a counter pressure against the pipe 13 when the pack is pressed down over the pipe. Through the openings 16 of the slats 10 and towards the pipe 13, a counter-hold 18 can thereby be introduced in the form of a steel rail or the like, which can be connected to a body that exerts pressure on the package (fig. 7). By this procedure is
det også hensiktsmessig, å anordne et trykkvirkende forankringsorgan 19 ved lamellpakkens ene ende, ifølge fig. 8 og 9, hvormed lamellenes 10 midtparti forskyves sfærisk til motsatt side, slik som tidligere angitt. Dette organ kan hensiktsmessig bestå av et U-formet stålstøtteorgan 19, som føres ned over røret 13 og mellom sidestykkenes 15, 15' ene endepartier, som kan være vinkel-bøyde og forsynt med mot stålstøtten 19 virkende skrueorgan 20. Stålstøtten 19 kan hensiktsmessig ved sin mot lamellenes rettede side, være sfærisk utadbuktet, for effektivt å muliggjøre nevnte forskyvning av lamellenes midtparti. it is also appropriate to arrange a pressure-acting anchoring member 19 at one end of the lamellar pack, according to fig. 8 and 9, whereby the middle part of the lamellae 10 is displaced spherically to the opposite side, as previously stated. This body can suitably consist of a U-shaped steel support body 19, which is guided down over the pipe 13 and between the end parts of the side pieces 15, 15', which can be bent at an angle and provided with a screw body 20 acting against the steel support 19. The steel support 19 can suitably its side facing the slats, be spherically convex, to effectively enable said displacement of the slats' middle part.
Ved hjelp av konvektoren ifølge oppfinnelsen kan effektive konvektorer anordnes ved ferdigtrukne rørsystemer på hensiktsmessige steder på disse. With the help of the convector according to the invention, efficient convectors can be arranged in ready-made pipe systems in suitable places on them.
