Abstract

The invention relates to an arrangement in a plate heat exchanger (1). Between the plates are flow channels, every other one of which is designed to receive the flow of a heat-emitting medium and every second one of which a heat-absorbing medium. The flow channels for one of the media, preferably the heat-absorbing medium, are connected in parallel via inlet and outlet ports to manifolds for the said medium. In one section on two opposing sides an opening (9') with a side wall (10) running round the edge (9'') of the opening and inclined somewhat inwards is made in the plates. The said side wall has an interruption (10') so that, with the side walls (10) of the plates telescoped in one another and connected pressure-tightly with one another by a joining process the side walls (10) form walls of the manifolds (8, 9) and the side wall interruptions (10') form inlet and outlet ports (10'') between the manifolds (8, 9) and the flow channels.

Description

15 20 30 35 511 072 2 strörnningskanalema är inrättade att genomströmmas av ett värmeupptagande medium, i föreliggande fall komprimerad lufi från gasturbinens kompressor. In- strömningen av denna till rekuperatom markeras med en pil 3 och utströmningen med en pil 4. The disturbance ducts are arranged to be flowed through by a heat-absorbing medium, in the present case compressed lu fi from the gas turbine compressor. The inflow of this to the recuperator is marked with an arrow 3 and the outflow with an arrow 4.

För att uppnå hög verkningsgrad i överföringen av termisk energi från det värmeav- givande till det värmeupptagande mediet skall ju medieflödena vara i huvudsak mot- riktade. Detta är fallet inom ett med 5 betecknat parti av genomströmningskanalerna för det värmeupptagande mediet. Med 6 resp 7 markeras partier i nämnda genom- strömningskanaler där flödena ej är motriktade, utan varandra korsande.In order to achieve high efficiency in the transfer of thermal energy from the heat-emitting medium to the heat-absorbing medium, the media fl fates must be substantially opposite. This is the case within a portion denoted by 5 of the flow channels for the heat-absorbing medium. With 6 and 7, respectively, portions are marked in the said flow channels where fl the fates are not opposite, but intersecting.

Det värmeupptagande mediets flöde 3 in i rekuperatom 1 går via en sarnlingskanal 8, som via inloppsportar i resp strömningskanal för det värmeupptagande mediet kom- municerar med sarnlingskanalen 8. På motsvarande sätt finns en kommunikation via utloppsportar i resp strömningskanal till en samlingskanal 9 för det värmeupptagande mediets flöde 4 ut ur rekuperatom. Så som närmare skall förklaras i det följ ande ansluter inloppsportarna till genomströmningskanalemas parti 6, medan ut- loppsportarna ansluter till genomströmriingskanalemas parti 7.The fate of the heat-absorbing medium 3 into the recuperator 1 goes via a flow channel 8, which communicates with the flow channel 8 via inlet ports in the respective heat-receiving channel for the heat-absorbing medium. the fate of the medium 4 out of the recuperator. As will be explained in more detail below, the inlet ports connect to the portion 6 of the flow channels, while the outlet ports connect to the portion 7 of the flow channels.

Med hänvisning till figurema 2 och 3, vilka visar snitt A-A resp B-B av rekuperatom 1 i fig 1, skall nu närmare förklaras anordnandet av in- och utloppsportarna och samlingskanalerna 8,9. Eftersom förhållandena är analoga vid de båda samlings- kanalerna hänvisas endast till uppbyggnaden i anslutning till sarnlingskanalen 9 och de nämnda delsnitten A-A resp B-B illustrerade i figurerna 2 resp 3.With reference to Figures 2 and 3, which show sections A-A and B-B, respectively, of the recuperator 1 in Figure 1, the arrangement of the inlet and outlet ports and the collection channels 8,9 will now be explained in more detail. Since the conditions are analogous to the two collection channels, reference is made only to the construction in connection with the collection channel 9 and the mentioned sub-sections A-A and B-B, respectively, illustrated in Figures 2 and 3, respectively.

I plattorna, av vilka rekuperatom är uppbyggd, är i ett parti vid två motstående sidor a, b upptagen en öppning 9” med en runt öppningens 9” kant 9” löpande sarg 10.In the plates, of which the recuperator is built up, an opening 9 "is accommodated in a portion at two opposite sides a, b with an edge 10" running around the opening 9 "edge 9".

Denna är något snedställd inåt mot öppningen 9”. I ett mot partiet 7 gränsande avsnitt av sargen 10 ñnns ett avbrott 10”. Med plattomas sarger iskjutna i varandra såsom illustreras i ñ g 2 och trycktätt förenade med varandra, t ex genom lödning, bildar sar- gema 10 sarnlingskanalens 9 väggar och avbrotten 10” utloppsportarna 10”', som för- binder samlingskanalen 9 med genomströmningskanalema för det värmeupptagande mediet. Dessa genomströmningskanaler är i ñgurema 2 och 3 betecknade med 11 medan det värmeupptagande mediets flöde markerats med pilar 4”. Genomström- ningskanalema för det värmeavgivande mediet är på motsvarande sätt markerade med 12.This is slightly inclined inwards towards the opening 9 ”. In a section of the rim 10 bordering the party 7, there is an interruption 10 ”. With the edges of the plates slid into each other as illustrated in ñ g 2 and pressure-tightly connected to each other, for example by soldering, the walls 10 of the arm 10 and the breaks 10 form the "outlet ports 10" ', which connect the collection channel 9 to the flow channels 9 for the heat-absorbing medium. These flow channels are denoted by 11 in Figures 2 and 3, while the fate of the heat-absorbing medium is marked by arrows 4 '. The flow channels for the heat-emitting medium are correspondingly marked with 12.

Företrädesvis bildas avbrottet 10” i resp plattas sarg 10 på så, sätt att som schematiskt visas i fig 3 det mot avbrottet 10” svarande sargpartiet 10”” böjts så, att det bildar en 10 5 1 1 Û 7 2 3 vinkel ot med plattans plan. Därigenom uppnås att sargpartiet 10”° bildar en ledskena för det värmeupptagande mediets strömning genom in- och utloppsportarna (1 O' ') Med fig 4 illustreras att samlingskanalemas 8, 9 ytterväggar liksom även rekupera- toms kortsidor i ett alternativt utförande är utåtbuktade. Den utåtbuktade formen ger en ökad uycktålighet, som förbättrar rekuperatoms livslängd.Preferably, the break 10 "is formed in or flattened edge 10 in such a way that, as schematically shown in fi g 3, the edge portion 10" corresponding to the break 10 "is bent so that it forms an angle ot with the plate. plan. Thereby it is achieved that the edge portion 10 "° forms a guide rail for the flow of the heat-absorbing medium through the inlet and outlet ports (1 O ''). With fi g 4 it is illustrated that the outer walls of the collection channels 8, 9 as well as the short sides of the recuperator are alternatively curved outwards. The outwardly curved shape provides increased impatience, which improves the life of the recuperator.

Genom att anordna samlingskanalema 8,9, in- och utloppsportarna och partiema 5, 6 och 7 av varandra motriktade resp korsande medieflöden enligt uppfinningen uppnås alltså en kompakt uppbyggnad och enkel tillverkning av en rekuperator, samtidigt som denna får hög verkningsgrad.By arranging the collection channels 8,9, the inlet and outlet ports and the sections 5, 6 and 7 of mutually opposite and intersecting media outlets according to the invention, a compact construction and simple manufacture of a recuperator is thus achieved, at the same time as this has a high efficiency.
