Description
Denne oppfinnelse angår platestabel-varmevekslere, og spesielt platestabel-varmevekslere med mindre manifolder. This invention relates to plate stack heat exchangers, and in particular to plate stack heat exchangers with smaller manifolds.
Varmevekslere med ribbeplater er hovedsakelig av en type med ribbe/kanal-konstruksjon. Motstrøm kan oppnås, men manifolder i en platestabel som må fluidene ved inlet og utlet blitt svært kompliserte. Siden manifolderne i varmevekslere av kryss-strøm-typen er forholdsvis enkel, er dette varmevekslersystem mest brukt, skjønt det er mindre effeftivt enn motstrøm-systemet, og det induserer alvorlige termiske og mekaniske påkjenninger. Heat exchangers with finned plates are mainly of a type with fin/channel construction. Counterflow can be achieved, but manifolds in a plate stack that must have the fluids at the inlet and outlet become very complicated. Since the manifolds in cross-flow type heat exchangers are relatively simple, this heat exchanger system is most widely used, although it is less efficient than the counter-flow system, and it induces severe thermal and mechanical stresses.
Et krysstrømsystem som forsøker å løse manifoldproblemene i motstrøms-varmeveksleren er vist Campbell og andre, U.S. patent nr. 3,305,010. Campbell viser en varmeveksler med overlagte plate- og ribbeelementer og en komplisert manifoldanordning for innføring av fluida med forskjellige temperaturer i motsatte ender av enheten. Campbell viser imidlertid ikke en plate som. vi tjene både som plate og ribbe, og heller ikke en anordning for indre manifoldutforming av platen innenfor dennes plan. A cross-flow system which attempts to solve the manifold problems in the counter-flow heat exchanger is shown in Campbell et al., U.S. Pat. Patent No. 3,305,010. Campbell shows a heat exchanger with superimposed plate and fin elements and a complicated manifold device for introducing fluids of different temperatures into opposite ends of the unit. However, Campbell does not show a record that. we serve both as plate and rib, and also not a device for internal manifold design of the plate within its plane.
Et av problemene ved platestabel-varmevekslere er blokker-ing av utvalgte indre åpninger på ethvert stabelnivå for å hindre at et fluid strømmer fra den valgte åpning gjennom kanalen på det nivået, for dermed å tvinge fluidet gjennom åpningen til det neste nivå, hvor det tillates å strømme gjennom kanalen. One of the problems with plate stack heat exchangers is the blocking of selected internal openings at any stack level to prevent a fluid from flowing from the selected opening through the channel at that level, thereby forcing the fluid through the opening to the next level, where it is allowed to flow through the channel.
Et formål med den foreliggende oppfinnelse er å frembringe en ribbe-plate for en platestabel-varmeveksler med indre manifolder. An object of the present invention is to produce a ribbed plate for a plate stack heat exchanger with internal manifolds.
Et annet formål er å frembringe en enkel anordning for å blokkere strømmen fra en fluid-innløpsåpning ved et gitt plate-nivå i en platestabel-varmeveksler og for å føre dette fluid til en innløpsåpning i den neste høyere plate. Another object is to provide a simple device for blocking the flow from a fluid inlet opening at a given plate level in a plate stack heat exchanger and for leading this fluid to an inlet opening in the next higher plate.
Andre formål, fordeler og nye trekk ved den foreliggende oppfinnelse vil fremgå fra den følgende detaljbeskrivelse i forbindelse med tegningene. Other purposes, advantages and new features of the present invention will be apparent from the following detailed description in connection with the drawings.
Oppfinnelsen omfatter en motstrøms-varmeveksler med stabl-ede, ribbede plater og indre manifolder, der hver indre plate har manifold-områder på motsatte ender. Åpninger for gjennom-strømning eller innløp er skåret ut i platene, minst to åpninger i hvert manifoldområde. Åpningene og ribbene er slik utformet at platene kan dreies 180 grader uten at det totale utseende endres, d.v.s. at åpningene i den roterte plate vil befinne seg på linje med åpningene i en ikke-rotert plate når de to platene er stablet. Bøssinger av sammenpressbart, fluidtett materiale er innlagt i to diagonalt motsatte åpninger i hver plate, og en pakning er lagt i et spor i den øvre overflate av veggen rundt periferien av platen, slik at fluid ikke kan strømme mellom pakning/bøssing og den nedre overflate av den platen som ligger umiddelbart over. The invention comprises a counter-flow heat exchanger with stacked, ribbed plates and inner manifolds, where each inner plate has manifold areas on opposite ends. Openings for through-flow or inlet are cut out in the plates, at least two openings in each manifold area. The openings and ribs are designed in such a way that the plates can be turned 180 degrees without the overall appearance changing, i.e. that the openings in the rotated plate will line up with the openings in a non-rotated plate when the two plates are stacked. Bushings of compressible, fluid-tight material are inserted into two diagonally opposite openings in each plate, and a gasket is placed in a groove in the upper surface of the wall around the periphery of the plate, so that fluid cannot flow between the gasket/bushing and the lower surface of the plate immediately above.
Oppfinnelsen skal i det følgende beskrives nærmere ved hen-visning til tegningene, hvor: Fig. 1 viser skjematisk utførelsen av to tilstøtende plater ifølge den foreliggende oppfinnelse. Fig. 2 viser skjematisk en ramme som kan brukes til å danne en periferisk vegg rundt en plate. Fig. 3 viser skjematisk en utførelse av platene i en platestabel-varmeveksler ifølge oppfinnelsen.

De samme elementer eller deler er betegnet med de samme henvisningstall på alle figurene, mens ekvivalente elementer har en merket betegnelse. The same elements or parts are designated by the same reference numbers in all the figures, while equivalent elements have a marked designation.
Det henvises først til Fig. 1, som viser et skjematisk riss av to indre, tilstøtende ribbe/kanal-plater 10 og 12 for en varmeveksler 50 (Fig.3) ifølge den foreliggende oppfinnelse. Den øvre og nedre plate 10 og 12 er fortrinnsvis rektangulære, og er utformet med parallelle langsgående, stående ribber 16 som danner langsgående kanaler 18 mellom dem. Platene kan være utformet i metall ved en ekstruderingsprosess, og områdene 20 og 21 (se Fig. 2) kan bli utformet senere, idet ribbene 16 blir frest ved hver ende. Et par adskilte fluid-innløpsåpninger 22 og 24 er boret ved en ende nær platenes hjørner, og nok et par åpninger er boret på lignende måte ved den andre enden. Reference is first made to Fig. 1, which shows a schematic diagram of two inner, adjacent rib/channel plates 10 and 12 for a heat exchanger 50 (Fig. 3) according to the present invention. The upper and lower plates 10 and 12 are preferably rectangular, and are designed with parallel longitudinal vertical ribs 16 which form longitudinal channels 18 between them. The plates can be formed in metal by an extrusion process, and the areas 20 and 21 (see Fig. 2) can be formed later, the ribs 16 being milled at each end. A pair of separate fluid inlet openings 22 and 24 are drilled at one end near the corners of the plates, and another pair of openings are similarly drilled at the other end.
En ramme 30 er plassert oppå og festet til periferien av den øvre overflate av hver ribbeplate, og danner således en vegg 31 rundt platen og en brønn eller manifold 32, 33 ved hver ende. hvor ribbene 16 er frest av. To diagonalt motsatte åpninger på hver plate er utstyrt med en innlagt bøssing 34 som strekker seg oppover så langt som til toppen av veggen 31 på rammen 30, og toppene av ribbene 16, idet toppoverflåtene av disse delene danner et flatt plan. Bøssingene 34 er fortrinnsvis utformet av et sammenpressbart materiale, f.eks. et varmebestandig elastomer-materiale, i hvilket tilfelle de kan strekke seg noe ovenfor det ovennevnte flateplan, eller de kan være utformet av metall med et spor i den øvre overflate i hvilket en sirkelrund pakning 36 eller O-ring kan legges inn. Ramme 30 er også fortrinnsvis utformet med et spor i sin øvre overflate, i hvilket en pakning 38 er innlagt. Bunnflatene av de indre platene 10 og 12, så vel som topplaten 14, må være flate overflater slik at de gjør god kontakt med pakningene 38 og 36 på rammene 30 og bøssingene 34 A frame 30 is placed on top and attached to the periphery of the upper surface of each rib plate, thus forming a wall 31 around the plate and a well or manifold 32, 33 at each end. where the ribs 16 have been milled off. Two diagonally opposite openings on each plate are provided with an inset bushing 34 which extends upwards as far as the top of the wall 31 of the frame 30, and the tops of the ribs 16, the top surfaces of these parts forming a flat plane. The bushings 34 are preferably made of a compressible material, e.g. a heat-resistant elastomeric material, in which case they may extend somewhat above the above plane, or they may be formed of metal with a groove in the upper surface into which a circular gasket 36 or O-ring may be inserted. Frame 30 is also preferably designed with a groove in its upper surface, in which a gasket 38 is inserted. The bottom surfaces of the inner plates 10 and 12, as well as the top plate 14, must be flat surfaces so that they make good contact with the gaskets 38 and 36 on the frames 30 and bushings 34
i de platene som ligger under overflatene. Pakningene 36 og 38 hindrer selvfølgelig gjennomstrømning av fluid. in the plates that lie below the surfaces. The seals 36 and 38 naturally prevent the flow of fluid.
Bunnplaten 10 merket (se Fig. 3) i platestabelen er utformet noe forskjellig fra de indre platene 10, 12 etc. Bunnplaten 10' er utformet med bare to åpninger 24' og 28', i hvert sitt manifoldområde og på den samme langsgående side av platen. En åpning 24' er innløpsåpningen for et fluid (B), f.eks. kjølig luft, og den andre åpningen 28' er innløpsåpning for et annet fluid (A), f.eks. varm olje som skal avkjøles. En bøssing 34 er satt inn gjennom innløpsåpningen 24' for det fluid som ikke skal sirkulere gjennom kanalene 18 i bunnplaten 10', og omformer dermed denne åpningen til en ikke-spredende åpning, d.v.s. en åpning gjennom hvilken fluid strømmer bare til den neste plate 12 ovenfor bunnplaten 10'. The bottom plate 10 marked (see Fig. 3) in the plate stack is designed somewhat differently from the inner plates 10, 12 etc. The bottom plate 10' is designed with only two openings 24' and 28', each in its manifold area and on the same longitudinal side of the plate. An opening 24' is the inlet opening for a fluid (B), e.g. cool air, and the second opening 28' is an inlet opening for another fluid (A), e.g. hot oil to be cooled. A bushing 34 is inserted through the inlet opening 24' for the fluid that is not to circulate through the channels 18 in the bottom plate 10', and thus transforms this opening into a non-spreading opening, i.e. an opening through which fluid flows only to the next plate 12 above the bottom plate 10'.
Pilene indikerer retningen av fluidstrømmen. Fluid A som er under trykk ledes således inn gjennom bunnplaten 10' gjennom inn-løpsåpningen 28', fyller manifoldet 33, og en del går videre gjennom kanalen 18 mellom ribbene 16 og opp gjennom innløpsåpn-ingen 22 i den andre platen 12. En annen del fortsetter direkte gjennom den ikke-spredende åpningen 28 i den andre platen 12, gjennom innløpsåpningen 28 i den tredje platen 10 hvor det danner kilden for fluidstrøm til venstre som i den første plate. The arrows indicate the direction of fluid flow. Fluid A, which is under pressure, is thus led in through the bottom plate 10' through the inlet opening 28', fills the manifold 33, and a part continues through the channel 18 between the ribs 16 and up through the inlet opening 22 in the second plate 12. Another part continues directly through the non-spreading opening 28 in the second plate 12, through the inlet opening 28 in the third plate 10 where it forms the source of fluid flow to the left as in the first plate.
Fluid B som er under trykk føres inn i bunnplaten 10' gjennom den ikke-spredende åpning 24', og blir hindret fra strømme inn i bunnplaten 10' av bøssingen 34. Fluid B går gjennom inn-løpsåpningen 24 i den andre platen 12, og fyller manifoldet 32 Fluid B under pressure is introduced into the bottom plate 10' through the non-spreading opening 24', and is prevented from flowing into the bottom plate 10' by the bushing 34. Fluid B passes through the inlet opening 24 in the second plate 12, and fills the manifold 32
på den venstre side. En del av manifold-fluidet strømmer til høyre gjennom kanalen 18, og så opp gjennom den ikke-spredende åpning 26 i platen 10 og åpningen 26 i plate 11. Det forlater platestabelen gjennom utløpskanalen 42 i topplaten 14, som er on the left side. A portion of the manifold fluid flows to the right through the channel 18, and then up through the non-spreading opening 26 in the plate 10 and the opening 26 in the plate 11. It leaves the plate stack through the outlet channel 42 in the top plate 14, which is
utformet med to utløpskanaler, 42 for fluid B og 40 for fluid A. Fluid B strømmer alltid til høyre i vekslende plater, f.eks. platene 12 og 11. For fluid B er åpningene 24' og 24 i hver plate innløpsåpninger, og åpningene 26 diagonalt motsatt er utløps-åpninger. For fluid A er åpningene 28' og 28 innløpsåpninger, og åpningene 22 er utløpsåpninger. Strømmene i kanalene 18 for fluidene A og B er motstrømmer. designed with two outlet channels, 42 for fluid B and 40 for fluid A. Fluid B always flows to the right in alternating plates, e.g. the plates 12 and 11. For fluid B, the openings 24' and 24 in each plate are inlet openings, and the openings 26 diagonally opposite are outlet openings. For fluid A, the openings 28' and 28 are inlet openings, and the openings 22 are outlet openings. The currents in the channels 18 for the fluids A and B are counter currents.
Det skal bemerkes at det er mange flere indre plater, skjønt disse er utelatt i tegningen. Alle indre plater 10, 11, 12 har den samme konstruksjon, skjønt to tilstøtende plater er rotert 180 grader fra hverandre. (Plate 10 kan være forskjellig bare i utelatelsen av åpningen 26.) It should be noted that there are many more inner plates, although these are omitted in the drawing. All inner plates 10, 11, 12 have the same construction, although two adjacent plates are rotated 180 degrees from each other. (Plate 10 may differ only in the omission of opening 26.)
På Fig. 4 er det vist en enhetlig konstruksjonsform for en pakning 62 som kan legges inn i et spor langs toppen av den periferiske vegg og de sirkelrunde pakningene 60 som kan legges legges på toppen av bøssingene 34. Fig. 4 shows a uniform design for a gasket 62 which can be placed in a groove along the top of the peripheral wall and the circular gaskets 60 which can be placed on top of the bushings 34.
Mange modifikasjoner og variasjoner i den foreliggende oppfinnelse er selvfølgelig mulig i henhold til de foregående for-klaringer. Det må derfor forstås at oppfinnelsen, innenfor om-fanget av kravene, kan utføres på andre måter enn hva som er be-skrevet. Many modifications and variations in the present invention are of course possible according to the preceding explanations. It must therefore be understood that the invention, within the scope of the claims, can be carried out in other ways than what is described.
