Description
Fremgangsmåte til fremstilling av et varmevekslerelement. Method for manufacturing a heat exchanger element.
Oppfinnelsen angår en fremgangsmåte til fremstilling av et varmevekslerelement med i rekker anordnete, parallelt med hverandre forlopende ror for gjennomstrømning av en varmebærer og med som luftledeplater virkende, med rorene sammenloddete tverrlameller.The invention relates to a method for producing a heat exchanger element with tubes arranged in rows, running parallel to each other, for the flow of a heat carrier and with transverse slats soldered together with the tubes acting as air baffles.
Slike varmevekslerelementer anvendes i det vesentlige som kjolere i kjoretoyer og fartoyer eller stasjonært. Anvendelse av elementene som varmelegemer til oppvarmning av lokaler er også mulig. Such heat exchanger elements are mainly used as coolers in vehicles and vessels or stationary. Use of the elements as heaters for heating premises is also possible.
Det har hittil vært alminnelig å montere elementene enkeltvis i den onskede storrelse. Da denne monteringsmåte er tidkreven-de og kostbar, er det fremkommet forslag om forst å montere varmevekslerblokker av en bredde som et antall elementer, og så skjære opp disse blokker til et antall elementer. Ved denne fremstillingsmåte oppstår der særlige vanskeligheter p.g.a. tverrlamellenes lille platetykkelse, som f.eks. kan utgjore kun 0,1 mm. Disse vanskeligheter består spesielt i at plate-kantene lett blir boyningsdeformert, selv ved valg av meget liten snitthastighet. Dessuten oppstår det stor friksjon mellom de frie platekanter av de allerede gjennomskårne lameller og sagbladet eller oppdelingsorganet, som likeledes forutsetter en meget lav snitthastighet. Man har forsokt å avhjelpe disse ulemper ved at der i tverrlamellene utformes avlange hull i områdene for snittplanene, slik at kun en brokdel av det samlede tverrsnitt av lamellene skal gjennom-skjæres. De ved denne foranstaltning oppnådde fordeler er absolutt utilstrekkelige, idet der stadig må arbeides med en meget lav snitthastighet, uten at faren for boyning av lamellkantene er fjernet. Dessuten er friksjonen mellom lamellkantene og skjæreorganet stadig uonsket stor. Oppfinnelsen tar sikte på å unngå disse ulemper og anvise Up until now, it has been common to assemble the elements individually in the desired size. As this assembly method is time-consuming and expensive, a proposal has been made to first assemble heat exchanger blocks of a width equal to a number of elements, and then cut these blocks into a number of elements. With this method of production, special difficulties arise due to the small plate thickness of the transverse slats, such as e.g. can amount to only 0.1 mm. These difficulties consist in particular in the fact that the plate edges are easily deformed by bowing, even when a very low cutting speed is chosen. In addition, great friction occurs between the free plate edges of the already cut through slats and the saw blade or the dividing member, which likewise requires a very low cutting speed. Attempts have been made to remedy these disadvantages by designing oblong holes in the transverse slats in the areas for the cut planes, so that only a fraction of the total cross-section of the slats must be cut through. The advantages achieved by this measure are absolutely insufficient, as work must be done at a very low cutting speed, without the danger of boying of the lamella edges being removed. In addition, the friction between the lamella edges and the cutting device is still undesirably high. The invention aims to avoid these disadvantages and to indicate
en fremgangsmåte ved hjelp av hvilken man kan fremstille en varmevekslerelement av forbedret konstruksjon under unngåelse av det vanlige spill av materiale fra store blokker på en særdeles rasjonell måté. a method by means of which one can produce a heat exchanger element of improved construction while avoiding the usual waste of material from large blocks in a particularly rational manner.
Fremgangsmåten er karakterisert ved at man ved sammenlodding av ror f.eks. med flatt tverrsnitt og tverrlameller fremstiller en varmevekslerblokk med en bredde lik flere elementbredder, og at man fra blokken ved ett eller flere, hvert gjennom en vertikal rorrekke lagt skillesnitt avsted-kommer varmevekslerelementer av onsket bredde, på en slik måte at eh halvdel av hvert av de i den angjeldende gjennomskårne rorrekke inngående ror danner en stabiliseringsstav i det ene element og den annen halvdel danner en stabiliseringsstav i et annet element. The procedure is characterized by the fact that when soldering rudders, e.g. with a flat cross-section and transverse lamellas, a heat exchanger block is produced with a width equal to several element widths, and that heat exchanger elements of the desired width are produced from the block at one or more, each through a vertical row of tubes, heat exchanger elements of the desired width, in such a way that eh half of each of the rudders included in the respective cut-through row of rudders form a stabilizing rod in one element and the other half forms a stabilizing rod in another element.
Da snittene fores gjennom stabiliseringsstavene, kan tverrlamellene, henholdsvis disses snittkanter ikke boyes under deleoperasjonen. Det kan derfor arbeides med hoy snitthastighet. En ytterligere fordel består i at de ved opp-delingen av en blokk i flere elementer dannede lengdeside-flater samtidig stabiliseres ved halvdelene av stabiliseringsstavene, d.v.s. delekantene av tverrlamellene er fast-lagt i deres innbyrdes avstand til stabiliseringsstavhalv-delene og er beskyttet mot deformerende boyning som folge av mekaniske påvirkninger. Det sistnevnte er for opplagringen, transporten og selv i montert tilstand av elementene av den aller storste betydning. As the cuts are guided through the stabilization rods, the transverse slats, or their cut edges, cannot be bent during the cutting operation. Work can therefore be done at a high average speed. A further advantage consists in that the longitudinal side surfaces formed by dividing a block into several elements are simultaneously stabilized by the halves of the stabilization rods, i.e. the dividing edges of the transverse slats are fixed in their mutual distance to the stabilizing rod halves and are protected against deforming bowing as a result of mechanical influences. The latter is for the storage, transport and even in assembled state of the elements of the greatest importance.
Ifolge oppfinnelsen kan snittbredden omtrent svare til den indre veggavstand av rorene med flatt tverrsnitt. According to the invention, the section width can roughly correspond to the inner wall distance of the rudders with a flat cross-section.
Spesielt når varmevekslerelementet anvendes som rom-varme-legeme er oppfinnelsen av den aller storste betydning. Selvom det til forskjellige bygningsprosjekter kreves elementer av forskjellig bredde, kan en vilkårlig mengde elementer pre-fabrikeres av elementer som blokker og holdes på lager. Etter ordreinngang skal bare et tilsvarende antall av disse blokker oppskjæres til elementer av onsket bredde, slik at hver bestilling kan leveres uten tidstap. Ellers alminnelige regningsforhoyelser for utforelse av smo ordrer reduseres til et minimum. Av de foran anforte grunner er det altså ved oppfinnelsen for forste gang blitt mulig å gjore et på samme måte som en bilkjoler utformet varmevekslerelement disponibelt for oppvarmningssektoren på bkonomislc måte. Especially when the heat exchanger element is used as a space heater, the invention is of the greatest importance. Although different building projects require elements of different widths, an arbitrary amount of elements can be pre-fabricated from elements such as blocks and kept in stock. After order entry, only a corresponding number of these blocks must be cut into elements of the desired width, so that each order can be delivered without loss of time. Otherwise, general bill increases for the execution of similar orders are reduced to a minimum. For the reasons stated above, the invention has for the first time made it possible to make a heat exchanger element designed in the same way as a car skirt available for the heating sector in an economical way.
På tegningen er vist en utforelsesform for et varmevekslerelement fremstilt i henhold til fremgangsmåten ifolge oppfinnelsen . The drawing shows an embodiment of a heat exchanger element produced according to the method according to the invention.
På tegningen betegner 1 horisontalt forlopende, vertikale og horisontale rekker dannende flate ror av et varmevekslerelement. De består av fortinnet messing. Deres utvendige tverrsnitt har en bredde av 2 mm og en hoyde av 12 mm. Vegg-tykkelsen er 0,25 mm, og den horisontale innbyrdes avstand fra midte ror til midte ror er 10 mm. Rorene 1 er fastholdt i forhold til hverandre ved hjelp av påtrukne, som luftledeplater tjenende lameller 2, som er 0,1 mm tykke og har liten innbyrdes avstand. 1 planene av de vertikale lengde-sideflater 3 og 4 av elementet ligger rorhalvdeler la av In the drawing, 1 denotes horizontally extending, vertical and horizontal rows forming flat tubes of a heat exchanger element. They consist of tinned brass. Their external cross-section has a width of 2 mm and a height of 12 mm. The wall thickness is 0.25 mm, and the horizontal mutual distance from center rudder to center rudder is 10 mm. The rudders 1 are held in relation to each other by means of drawn lamellas 2, which serve as air baffles, which are 0.1 mm thick and have a small mutual distance. 1 the planes of the vertical length-side surfaces 3 and 4 of the element lie rudder halves la of
en vertikal rorrekke (kun lengdesideflaten 3 er synlig). Tverrlamellene består av jernplate, som er overtrukket med bly. a vertical row of rudders (only the longitudinal side surface 3 is visible). The transverse slats consist of iron plate, which is coated with lead.
Rorhalvdelene la er fremkommet ved at rorene 1 og luftlede-platene (tverrlamellene) 2 forst er blitt sammenfoyet til en blokk med en bredde som et antall elementer, er blitt loddet og deretter er blitt skåret opp til elementer av onsket storrelse. Som folge av den flate rortverrsnittsform og en tilsvarende snittbredde fås de flate avslutningsstrimler (rorhalvdeler) la, som folgelig ligger forsenket i utspar-inger i lamellkantene og stabiliserer lengdesidekantene 3,4, hhv. de lengdesideflatene 3 og 4 dannende kanter av luftledeplåtene 2, såvel under oppdelingsoperasjonen som mot senere mekaniske påvirkninger. The rudder halves 1a have been produced by the rudders 1 and the air guide plates (transverse slats) 2 having first been joined into a block with a width equal to a number of elements, have been soldered and then have been cut up into elements of the desired size. As a result of the flat rudder cross-section shape and a corresponding section width, the flat end strips (rudder halves) are obtained, which consequently lie recessed in recesses in the lamella edges and stabilize the longitudinal side edges 3,4, respectively. the longitudinal side surfaces 3 and 4 forming edges of the air guide plates 2, both during the splitting operation and against later mechanical influences.
Endesidene av elementet dannes av endeplater 5, av hvilke kun én er synlig. The end sides of the element are formed by end plates 5, of which only one is visible.
