Den foreliggende opfindelse angår en loddet pladevarme veksl er omfattende en stabel plader, der har bølgeformede overflader, som danner indbyrdes krydsende kanaler imellem hver efterfølgende plade i pladestablen, og som ved hver ende har to sidestillede åbninger for mediernes gennemstrømning mellem de forskellige lag, samt støttebun-5 de, der er anbragt på hver side af pladestablen, og hvor en første støttebund er forsynet med ind- og udløbsåbninger for de gennemstrømmende medier.The present invention relates to a brazed plate heat exchange comprising a stack of plates having corrugated surfaces forming intersecting channels between each subsequent plate in the plate stack and having at each end two parallel openings for media flow between the various layers, -5 are provided on each side of the sheet stack and wherein a first support bottom is provided with inlet and outlet openings for the flowing media.
Der kendes pladevarmevekslere, som består af en stabel tynde plader. Pladerne presses imod hinanden, således at der dannes varmeudvekslingskamre mellem pladerne. Hver 10 plade vil være forsynet med fire passagéåbninger. To af disse er beregnet til det ene medie, og de to andre åbninger er beregnet til det andet medie i varmeveksleren. Passa-geåbningeme definerer forbindelser mellem hvert andet kammer i pladestablen for at etablere mediestrømningen gennem varmeveksleren. På grund af varmevekslerens opbygning vil ind- og udløbsåbninger for de to medier, som passerer gennem varmeveks-15 leren, passere ud gennem den første støttebund ved stillinger ud for passageåbningeme i pladerne. Disse ind- og udløbsåbninger vil således være dannet ved hjørnerne af et rektangel, der befinder sig inden for varmevekslerens tværsnitsprofil. Dette volder ulemper ved montage. Der vil således kræves bøjninger for at føre rør fra de to ijemeste åbninger ind til en understøtning eller en væg, hvorpå varmeveksleren normalt vil være monteret 20 i brug. Dette kræver manuel tilpasning på stedet og vil medføre risiko for utætheder, da sådanne rørbøjninger vil medføre flere samlinger/lodninger. Endvidere vil sådanne rørbøjninger være æstetisk uønskede at se på.Plate heat exchangers are known which consist of a stack of thin plates. The plates are pressed against each other so that heat exchange chambers are formed between the plates. Each 10 plate will be provided with four passage openings. Two of these are for one medium and the other two openings are for the other medium in the heat exchanger. The passage openings define connections between each other chamber in the plate stack to establish the media flow through the heat exchanger. Due to the structure of the heat exchanger, inlet and outlet openings for the two media passing through the heat exchanger will pass out through the first support floor at positions adjacent the passage openings in the plates. Thus, these inlet and outlet openings will be formed at the corners of a rectangle located within the cross-sectional profile of the heat exchanger. This causes the disadvantages of assembly. Thus, bends will be required to pass pipes from the two innermost openings to a support or wall on which the heat exchanger will normally be mounted 20 in use. This requires manual on-site adaptation and will pose a risk of leaks as such pipe bends will cause multiple joints / brazing. Furthermore, such pipe bends will be aesthetically undesirable to look at.
Der er således ønske om en loddet varmeveksler, hvor alle rørene er placeret ved den 25 ene sidekant af varmeveksleren, som i brug er beregnet til at blive monteret imod en væg, for således at opnå et produkt, som er let at montere, og som har lille risiko for utætheder. Dette opnås ifølge den foreliggende opfindelse med en pladevarmeveksler af den indledningsvis nævnte type, som er særpræget ved, at den første støttebund er forsynet med mindst to kanaldannende elementer, der er i forbindelse med en af de sidestil-30 lede åbninger i hver ende af varmeveksleren og danner en kanal, der forløber skråt i retning mod et plan gennem de to andre åbninger, og som udmunder i en åbning i nævnte plan, således at alle ind- og udløbsåbninger er placeret på linie.Thus, there is a desire for a soldered heat exchanger, where all the pipes are located at the one side edge of the heat exchanger, which in use is intended to be mounted against a wall, so as to obtain a product which is easy to assemble and which have little risk of leaks. This is achieved according to the present invention with a plate heat exchanger of the type mentioned initially, which is characterized in that the first support bottom is provided with at least two duct forming elements which are connected to one of the adjacent openings at each end of the heat exchanger. and forming a channel which extends obliquely towards a plane through the other two openings and which opens into an opening in said plane so that all inlet and outlet openings are aligned.

De kanaldannende: elementer vil udgøre en integreret del af pladevarmeveksleren og vil fremstilles samtidig med fremstillingen af varmeveksleren. Dette betyder, at der er lille risiko for utætheder. Ved anvendelsen af kanalelementeme føres alle varmevekslerens ind- og udløbsåbninger ind i et og samme plan, som kan befinde sig tæt ved den side af varmeveksleren, som i brug er monteret på en væg. Med andre ord kan man sige, at det kanaldannende element afblænder en åbning, som befinder sig fjernest fra en væg og leder mediet ind til en ind-/udløbsåbning ved varmevekslerens bagside. Herved kan varmeveksleren let forbindes med tilslutningsrør, som alle kan være anbragt i et rørbatteri eller på rørbøjler, som alle har placeret sådanne tilslutningsrør i samme afstand fra den væg, hvorpå varmeveksleren også er monteret. Alle ind- og udløbsåbninger vil fortrinsvis være forsynet med studse, og disse studse vil have forskellig højde, således at studsenes ende fjernest fra varmeveksleren befinder sig i samme plan, der forløber parallelt med den første støttebund. Herved opnås en særlig enkel måde at montere varmeveksleren på en væg, hvorved risiko for utætheder undgås.The duct forming elements will form an integral part of the plate heat exchanger and will be manufactured simultaneously with the manufacture of the heat exchanger. This means that there is little risk of leaks. When using the duct elements, all the inlet and outlet openings of the heat exchanger are introduced into one and the same plane, which may be close to the side of the heat exchanger mounted on a wall in use. In other words, it can be said that the duct-forming element blinds an opening which is farthest from a wall and leads the medium into an inlet / outlet opening at the back of the heat exchanger. Hereby the heat exchanger can be easily connected to connecting pipes, all of which may be arranged in a pipe battery or on pipe hangers, all of which have placed such connecting pipes at the same distance from the wall on which the heat exchanger is also mounted. All inlet and outlet openings will preferably be provided with studs, and these studs will have different heights, so that the ends of the studs farthest from the heat exchanger are in the same plane extending parallel to the first support floor. This provides a particularly simple way of mounting the heat exchanger on a wall, thereby avoiding the risk of leaks.
Ifølge en foretrukket udførelsesform er de kanaldannende elementer dannet af separate oppressede pladedele, som indlægges og fastloddes i udstansede spor i den første støttebund. Ved at indlægge de kanaldannende elementer i det udstansede spor opnås en stor loddeflade, hvilket giver en stor sikkerhed for et tæt produkt, og samtidig opnås et æstetisk tiltalende produkt, der har en glat overflade. Idet en støttebund af styrkemæssige årsager har en relativ stor tykkelse, foretrækkes det, at pladetykkelsen for de kanaldannende elementer kun fremstilles i halv tykkelse, da den derved bliver lettere at oppresse.According to a preferred embodiment, the channel forming elements are formed of separate pressed plate parts which are inserted and fixed in punched grooves in the first support bottom. By inserting the channel forming elements in the punched groove, a large solder surface is obtained, which provides a high degree of security for a dense product, and at the same time an aesthetically pleasing product having a smooth surface is obtained. Since a support bottom has a relatively large thickness for strength reasons, it is preferred that the sheet thickness of the duct forming elements is only made in half thickness, as it thereby becomes easier to compress.
I det udstansede spor anvendes der derfor fortrinsvis en løs mellemplade, således at den totale pladetykkelse for mellempladen og pladedelene for det kanaldannende element har en tykkelse, som svarer til tykkelsen af bundpladen. Alternativt kan de kanaldannende elementer være separate oppressede pladedele, der er lagt uden på den første støttebund via en flange, som giver en stor loddeflade.Therefore, in the punched groove, a loose intermediate plate is preferably used so that the total plate thickness of the intermediate plate and the plate parts of the channel forming element have a thickness corresponding to the thickness of the base plate. Alternatively, the channel forming elements may be separate, pressed plate members which are laid out on the first support base via a flange which provides a large solder surface.
Anvendelsen af et udstanset spor i den første støttebund giver endvidere en fordel ved fremstilling af varmeveksleren, idet der spares et fikstur ved montagen af de kanaldannende elementer. Ved anvendelsen af det udstansede spor opnås der således en meget 3 DK 96 00205 U3 præcis placering af alle studsene, hvilket er meget vigtigt, da der stilles store krav til tolerancer for at undgå risiko for utætheder i varmeveksleren.The use of a punched groove in the first support floor further provides an advantage in producing the heat exchanger, saving a fixture in the assembly of the duct forming elements. Thus, when using the punched track, a very precise positioning of all the studs is achieved, which is very important as high tolerances are required to avoid the risk of leaks in the heat exchanger.
Såfremt varmeveksleren er forsynet med et yderligere kanaldannende element, der er indrettet til at optage en termoføler, kan der dannes en termofølerlomme, som er i kontakt med en af ind- og udløbsåbningeme. Et sådant yderligere kanaldannende element vil fortrinsvis have en orientering forløbende parallelt med planet for varmevekslerens ind- og udløbsåbninger. Herved vil termofølerelementet i en normal brugssituation være placeret inde under varmeveksleren og optage meget lidt plads. En termofølerlomme vil fortrinsvis være fremstillet af en separat oppresset pladedel, således som omtalt ovenfor. Ved dannelse af en termofølerlomme i et yderligere kanaldannende element kan der måles på mediet direkte ved en ind-/udløbsåbning. Det bliver muligt at anvende følerudstyr m.v., som kendes fra andre produkter til at styre/regulere gennemstrømningen gennem varmeveksleren. Selv om de kanaldannende elementer fortrinsvis udgøres af separate oppressede pladedele, vil det alternativt være muligt at fremstille disse kanaldannende elementer med en oppresning direkte af bundpladen.If the heat exchanger is provided with an additional duct forming element adapted to receive a thermocouple, a thermocouple pocket may be formed which is in contact with one of the inlet and outlet openings. Such additional duct forming element will preferably have an orientation extending parallel to the plane of the heat exchanger inlet and outlet. Hereby, in a normal use situation, the thermocouple element will be located under the heat exchanger and take up very little space. A thermo-sensor pocket will preferably be made of a separately pressed plate member, as discussed above. By forming a thermocouple pocket in a further duct forming element, the medium can be measured directly at an inlet / outlet opening. It becomes possible to use sensor equipment etc., which is known from other products to control / regulate the flow through the heat exchanger. Alternatively, although the channel forming elements are constituted by separate, pressed plate members, it will be possible to produce these channel forming elements with an upright directly from the base plate.
I en loddet pladevarmeveksler stilles der meget høje krav til tolerancer og samlinger, da de normalt er beregnet til et meget højt tryk på op til 150-200 bar. Den foreliggende opfindelse bibringer derfor en fordel ved at anvise en pladevarmeveksler, der kan fremstilles industrialiseret, og hvor et efterfølgende montagearbejde med rørtilslutninger, rørbøjninger m.v. er reduceret til et minimum. Herved er risiko for eventuelle lækager minimeret.In a brazed plate heat exchanger, very high demands are placed on tolerances and joints, as they are usually designed for a very high pressure of up to 150-200 bar. The present invention therefore provides an advantage of providing a plate heat exchanger which can be manufactured industrially and wherein a subsequent assembly work with pipe connections, pipe bends, etc. is reduced to a minimum. This minimizes the risk of any leaks.
Opfindelsen vil herefter forklares nærmere under henvisning til den medfølgende tegning, hvor fig. 1 viser et partielt snitbillede gennem en pladevarmeveksler til lodret mon tering på en væg med studsene vendende nedefter ifølge opfindelsen, fig. 2 et partielt eksploderet billede til illustration af de forskellige elementer, der indgår i en pladevarmeveksler ifølge opfindelsen, 4 DK 96 00205 U3 fig. 3 et partielt eksploderet billede af en anden udførelsesform for en varme veksler ifølge opfindelsen, fig. 4-8 forskellige enkeltelementer, som indgår i varmevekslere ifølge opfindel· sen.The invention will then be explained in more detail with reference to the accompanying drawing, in which fig. 1 shows a partial sectional view through a plate heat exchanger for vertical mounting on a wall with the studs facing downwards according to the invention; FIG. 2 is a partial exploded view illustrating the various elements included in a plate heat exchanger according to the invention; FIG. Figure 3 is a partially exploded view of another embodiment of a heat exchanger according to the invention; 4-8 different single elements included in heat exchangers according to the invention.
Indledningsvis bemærkes det, at tegningens forskellige figurer ikke er indbyrdes målfaste. Endvidere bemærkes det, at identiske henvisningsbetegnelser i de forskellige figurer, vil betegne identiske eller tilsvarende dele i de forskellige varmevekslere.Initially, it is noted that the various figures in the drawing are not mutually fixed. Furthermore, it is noted that identical reference numerals in the various figures will denote identical or similar parts in the different heat exchangers.
1 betegner en øverste støttebund, og 2 betegner en nederste støttebund. Derimellem er anbragt et antal på for eksempel 8-32 varmevekslerplader 3, hvoraf kun én er vist for overskuelighedens skyld. Varmeveksleren indeholder endvidere en topplade 4 og en bundplade 5, som er placeret mellem pladestablen og støttebundene 1,2.1 denotes an upper support floor and 2 denotes a lower support floor. In between there are arranged a number of, for example, 8-32 heat exchanger plates 3, only one of which is shown for the sake of clarity. The heat exchanger further contains a top plate 4 and a bottom plate 5, which is located between the plate stack and the support bottoms 1,2.
Hver varmevekslerplade 3 har en bølgeformet overflade 6 samt to sidestillede åbninger 7,8 ved hver ende. Åbningerne 7,8 forbinder hvert andet mellemrum mellem pladerne 3 for at danne kanaler for mediet, der strømmer gennem varmeveksleren. Den nederste støttebund 2 (se fig. 5 og 6) er forsynet med ind- og udløbsåbninger 7\8’ ved hver ende med en placering svarende til placeringen for gennemstrømningsåbningeme 7,8 i var-mevekslerplademe 3. Åbningerne 7’ udgør i den viste udførelsesform en del af et udstanset spor 9 i den nederste bundplade 2.Each heat exchanger plate 3 has a wavy surface 6 as well as two juxtaposed openings 7.8 at each end. The openings 7,8 connect every other space between the plates 3 to form channels for the medium flowing through the heat exchanger. The lower support base 2 (see Figs. 5 and 6) is provided with inlet and outlet openings 7 \ 8 'at each end with a position corresponding to the location of the flow openings 7,8 in the heat exchanger plates 3. The openings 7' form in the shown embodiment. embodiment part of a punched groove 9 in the lower base plate 2.
Sporene 9 er beregnet til optagelse af et kanaldannende element i form af en separat oppresset pladedel 10 (se fig. 8). Den oppressede pladedel 10 har en pladetykkelse svarende til den halve af pladetykkelsen for støttebunden 2.1 bunden af et spor 9 indlægges der derfor en separat indsatsplade 11 (se fig. 7), som samtidig definerer åbningen 7\ Ovenover indsatspladen 11 anbringes den oppressede pladedel 10 med den ene ende 12 over åbningen 7\ Ved den anden ende 13 af den oppressede pladedel 10 er der dannet en åbning 14. Når den oppressede pladedel er monteret i sporet 9, vil den således danne en kanal, der forløber skråt i retning bagud mod et plan 15 gennem de to andre åbninger 8’. Åbningen 14 vil befinde sig i nævnte plan 15, således at alle ind- og udløbsåbninger fra varmeveksleren er placeret på en linie langs nævnte plan. Ind- og udløbsåbningemeThe grooves 9 are intended to receive a channel forming element in the form of a separately pressed plate portion 10 (see Fig. 8). The pressed-up plate portion 10 has a plate thickness equal to half the plate thickness of the support base 2.1 the bottom of a groove 9, therefore a separate insert plate 11 is inserted (see Fig. 7), which at the same time defines the opening 7 \ Above the insert plate 11, the pressed-up plate part 10 is placed with one end 12 over the opening 7 \ At the other end 13 of the pressed plate portion 10 is formed an opening 14. When the pressed plate portion is mounted in the groove 9, it will thus form a channel extending obliquely in the rearward direction towards a plane 15 through the other two apertures 8 '. The opening 14 will be in said plane 15 so that all inlet and outlet openings from the heat exchanger are located on a line along said plane. The inlet and outlet openings
5 DK 96 00205 U3 8’ og 14 er forbundet med studse 16,17, som vil have en forskellige længde. Studsen 17, der er beregnet til at blive placeret i åbningen 14, vil således være kortere end studsen 16, der er beregnet til at være placeret i åbningen T. Herved vil studsenes ydre ende 18 alle befinde sig i samme plan, der forløber stort set parallelt med den første støttebund 2. Dette letter en montering. Planet 15, hvori ind- og udløbsåbningeme 8’, 14 er placeret, vil befinde sig ved den side 19 af varmeveksleren 1, som i brug vil være monteret på en væg. Studsene 16,18 vil således være placeret nær ved væggen.And DK 14 00205 U3 8 'and 14 are connected to studs 16,17 which will have a different length. Thus, the socket 17, which is intended to be placed in the opening 14, will be shorter than the socket 16, which is intended to be located in the opening T. Hereby, the outer end 18 of the socket will all be in the same plane extending substantially parallel to the first support base 2. This facilitates mounting. The plane 15 in which the inlet and outlet openings 8 ', 14 are located will be located on the side 19 of the heat exchanger 1, which will be mounted on a wall in use. Thus, the studs 16,18 will be located near the wall.
Bundpladen 2, der er vist i fig. 6, er beregnet til anvendelse i en varmeveksler, som er illustreret i fig. 1 og 2 sammen med den oppressede pladedel 10 og indsatspladen 11.The bottom plate 2 shown in FIG. 6 is intended for use in a heat exchanger illustrated in FIG. 1 and 2 together with the upright plate portion 10 and insert plate 11.
I fig. 1 og 2 er varmeveksleren vist med en orientering, som den normalt vil have i brug, nemlig med studsene 16,17 vendende nedefter.In FIG. 1 and 2, the heat exchanger is shown in an orientation that it would normally use, namely with the studs 16,17 facing downwards.
I fig. 3 er varmeveksleren vist med bunden i vejret i forhold til den brugssituation, der er vist i fig. 1.1 denne figur er der illustreret en yderligere udførelsesform, hvor der i venstre side er dannet et yderligere kanaldannende element 20. Dette kanaldannende element 20 er dannet af en oppresset pladedel, der udgør en termofølerlomme, som er placeret med en orientering forløbende stort set parallelt med varmevekslerens bredderetning. Det kanaldannende element 20 er i den viste udformning dannet ud i et med en del 21 svarende til den oppressede pladedel 10, men som er forsynet med en sideåbning, således at der er etableret en forbindelse mellem den kanal, som dannes af delen 21, og den kanal, som dannes af delen 20. Begge disse kanaler er i forbindelse med åbningen T.In FIG. 3, the heat exchanger is shown with the bottom in relation to the use situation shown in FIG. In this figure, a further embodiment is illustrated, in which a further channel forming element 20 is formed on the left side. This channel forming element 20 is formed by an upwardly pressed plate part constituting a thermocouple pocket which is positioned with an orientation extending substantially parallel to the heat exchanger width direction. In the illustrated embodiment, the channel forming element 20 is formed in one with a part 21 corresponding to the pressed plate part 10, but which is provided with a side opening, so that a connection is established between the channel formed by the part 21, and the channel formed by the portion 20. Both of these channels are in connection with the opening T.
Det kanaldannende element 20’s oppressede plade har en åbning 22, der er forsynet med en studs 23, og som er indrettet for at optage et termofølerelement 24. Termofølerele-mentet er placeret på en understøtning bestående af en oppresset pladedel 25. Den oppressede pladedel 25 har en halv tykkelse, ligesom pladen, der benyttes til det kanaldannende element 20, også har en halv tykkelse i forhold til bundpladen 2. Understøtningen 25 omfatter en del 26, der i det væsentlige svarer til indsatspladen 11.The upright plate of the channel forming element 20 has an opening 22 provided with a stud 23 which is adapted to receive a thermo-sensing element 24. The thermo-sensing element is located on a support consisting of an upright plate member 25. The upright plate member 25 has half the thickness, just like the plate used for the channel forming element 20, also has a half thickness relative to the base plate 2. The support 25 comprises a part 26 which corresponds substantially to the insert plate 11.
