Description
Anordning ved kjøleelement Device at cooling element
Oppfinnelsen gjelder en anordning ved et kjøleelement som angitt i innledningen til patentkrav 1. The invention relates to a device for a cooling element as stated in the introduction to patent claim 1.
Bakgrunn Background
Ved oppbygging av lamellkjølere, det vil si kjølelement med platelameller som anordnes i en luftstrøm som skal kjøles, er det viktig å oppnå god utveksling mellom luft og metall. Avstanden mellom kjølelamellene er blitt tilpasset produksjonsteknikken, vanligvis uten full optimalisering i forhold til størrelsen. When constructing lamella coolers, i.e. cooling elements with plate lamellas which are arranged in an air stream to be cooled, it is important to achieve good exchange between air and metal. The distance between the cooling fins has been adapted to the production technique, usually without full optimization in relation to the size.
I forskjellige sammenhenger er plassen begrenset, slik at en ønsker en å gjøre kjølelementene så små som mulig. In various contexts, space is limited, so you want to make the cooling elements as small as possible.
Fra US-patentskrift 3,267,692 er det kjent en lamellkjøler hvor luft skal blåses igjennom. Denne har til oppgave å redusere avisingsfrekvensen. Den er uegnet for bruk ved kjøleoppgaver hvor gravitasjon sørger for at kald luft faller ned av seg selv. From US patent 3,267,692, a lamella cooler is known where air must be blown through. This has the task of reducing the frequency of de-icing. It is unsuitable for use in cooling tasks where gravity ensures that cold air falls down by itself.
Formål Purpose
Hovedformålet med oppfinnelsen er derfor å skape et kjøleelement som er innrettet for bruk ved gravitasjonsstyrt luftgjennomgang og som har større effektivitet enn tilsvarende kjente kjøleelement. The main purpose of the invention is therefore to create a cooling element which is designed for use with gravity-controlled air passage and which has greater efficiency than corresponding known cooling elements.
Oppfinnelsen The invention
Oppfinnelsen er angitt i patentkrav 1. Den gjelder altså en anordning hvor kjøleelementet er innrettet for bruk ved gravitasjonsstyrt luftgjennomgang med oppovervendt innløpsende og nedovervendt utløpsende, og hvor det er anordnet vekselvis kjølelameller som strekker seg opp til innløpsenden og kjølelameller som strekker seg opp til en posisjon under innløpsenden, slik at luft faller fra bredere spalter til smalere spalter og gjennom disse. The invention is stated in patent claim 1. It therefore applies to a device where the cooling element is designed for use in gravity-controlled air passage with an upward-facing inlet end and a downward-facing outlet end, and where alternate cooling lamellas extending up to the inlet end and cooling lamellas extending up to a position are arranged below the inlet end, so that air falls from wider slits to narrower slits and through these.
Med denne utformingen er det blitt mulig å oppnå en vesentlig økning i kuldeoverføringen og senkning av temperaturen på luft som strømmer gjennom et slikt kjøleelement. Denne økningen antas å ha sin årsak i at luftmolekylene vil få økt kollisjon med kjølelamellene gjennom den trinnvise avsnevringen av bredden på luftspaltene. With this design, it has become possible to achieve a significant increase in cold transfer and lowering of the temperature of air flowing through such a cooling element. This increase is believed to be due to the fact that the air molecules will have an increased collision with the cooling fins through the gradual narrowing of the width of the air gaps.
I patentkrav 2 - 4 er det angitt særlig gunstige detaljer ved oppfinnelsen. Flere detaljer om dette vil gå fram av den etterfølgende eksempelskrivelsen. In patent claims 2 - 4, particularly favorable details of the invention are stated. More details about this will emerge from the following sample writing.
Eksempel Example
Oppfinnelsen er nedenfor beskrevet nærmere under henvisning til tegningene, hvor The invention is described below in more detail with reference to the drawings, where
Figur 1 viser et sideriss av en utførelsesform av oppfinnelsen, med et kjøleelement med lameller på kjølerør, mens Figure 1 shows a side view of an embodiment of the invention, with a cooling element with lamellae on cooling pipes, while
Figur 2 viser et forstørret utsnitt av lamellene i Figur 1, Figure 2 shows an enlarged section of the slats in Figure 1,
I Figur 1 er det vist et kjølelement 11 som er bygd opp mellom to endebraketter 12 og 13. Mellom endebrakettene 12 og 13 strekker det seg i eksemplet to par U-formete kjølerør 14 og 15 som blir tilkoblet for gjennomstrømning av kuldemedium. Kjølerørene 14 og 15 bærer ei rekke kjølelameller 16 og 17, som er anbragt vekselvis. Kjølelamellene 16 strekker seg i full høyde av kjøleelementet 11, og er festet til begge de U-formete kjølerørene 14,15, mens de øvrige kjølelamellene 17 har halvparten så stor utstrekning i høyden som kjølelamellene 16 og er festet til det nedre U-formete kjølerøret 14. In Figure 1, a cooling element 11 is shown which is built up between two end brackets 12 and 13. Between the end brackets 12 and 13, in the example, two pairs of U-shaped cooling pipes 14 and 15 extend, which are connected for the flow of coolant. The cooling pipes 14 and 15 carry a number of cooling fins 16 and 17, which are placed alternately. The cooling fins 16 extend to the full height of the cooling element 11, and are attached to both U-shaped cooling pipes 14,15, while the other cooling fins 17 extend half as far in height as the cooling fins 16 and are attached to the lower U-shaped cooling pipe 14.
Avstanden mellom kjølelamellene kan være 9 millimeter i den øvre delen og 2,5 - 3 millimeter i den nedre delen. Dette betyr en vesentlig reduksjon av lamellavstanden i forhold til tilsvarende kjente kjøleelement. Samtidig betyr det en økning i effektiviteten i varmeoverføringen. Grunnen til denne effektivitetsøkningen er ikke klarlagt, men det antas at den kan forklares ved at den trange lamellavstanden fører til økt molekylbevegelse og dermed til flere kollisjoner mellom luftmolekylene. The distance between the cooling fins can be 9 millimeters in the upper part and 2.5 - 3 millimeters in the lower part. This means a significant reduction of the lamella distance compared to corresponding known cooling elements. At the same time, it means an increase in the efficiency of heat transfer. The reason for this increase in efficiency is not clear, but it is assumed that it can be explained by the fact that the narrow lamella spacing leads to increased molecular movement and thus to more collisions between the air molecules.
Luftmolekyler som blir avkjølt ved overgangen fra en vid til en trangere del av lamellspaltene, antas å få økt spesifikk tyngde og dermed falle hurtigere og samtidig oscillere saktere og skape færre kollisjoner med nabomolekyler. Air molecules that are cooled by the transition from a wide to a narrower part of the lamellar gaps are assumed to have an increased specific gravity and thus fall faster and at the same time oscillate more slowly and create fewer collisions with neighboring molecules.
En reduksjon av lamellavstanden til under ca. 2,5 millimeter vil føre til risiko for gjenriming og tiltetning. A reduction of the slat spacing to less than approx. 2.5 millimeters will lead to a risk of re-rhyming and sealing.
Kjøleelementet 11 i eksemplet er vist med vertikal spalteorientering, med gravitasjonstyrt luftgjennomløp. The cooling element 11 in the example is shown with vertical slot orientation, with gravity-controlled air flow.
Kjøleelmentet 11 i samsvar med oppfinnelsen kan brukes for forskjellige kjøleformål, både teknisk og i boliger og kontorer. Det er for eksempel egnet for kjøleelement som skal plasseres frittliggende over godset som skal kjøles. The cooling element 11 in accordance with the invention can be used for various cooling purposes, both technically and in homes and offices. It is, for example, suitable for cooling elements that are to be placed free-standing above the goods to be cooled.
Modifikasjoner Modifications
Det er også mulig å oppnå tilsvarende fordeler ved andre oppbygninger av trinnvis innsnevrete lamellavstander. Det kan brukes to eller flere korte lameller mellom hvert par med full utstrekning. Eller det kan lages flere trinnvise avkortinger. Forutsetningen er at de trangeste spaltene eller lamellavstandene er i området 2,5 til 3 millimeter. It is also possible to achieve similar advantages with other constructions of progressively narrower lamella distances. Two or more short slats may be used between each full-span pair. Or several gradual cuts can be made. The prerequisite is that the narrowest gaps or lamella distances are in the range of 2.5 to 3 millimeters.
