Description

7805240-4 h.) utvinning av energi ur t ex sjövatten. Aggregatet som utgör ett slutet system inne- hållande ett värmeutväxlingsmedium med nedsatt fryspunkt, kan läggas direkt í sjön. 7805240-4 h.) Extraction of energy from eg seawater. The unit, which is a closed system containing a heat exchange medium with a reduced freezing point, can be placed directly in the lake.

Uppfinningen kommer närmare att beskrivas nedan under hänvisning till bifogad rit- ning, som visar en utföringsform av uppfinningen.The invention will be described in more detail below with reference to the accompanying drawing, which shows an embodiment of the invention.

Fig. 1 visar schematiskt en anläggning, i vilken en eller flera värmeväxlare enligt uppfinningen kan ingå. Fig. 2 visar ett horisontellt snitt av en värmeväxlare enligt uppfinningen.Fig. 1 schematically shows a plant in which one or more heat exchangers according to the invention can be included. Fig. 2 shows a horizontal section of a heat exchanger according to the invention.

I fig. 1 betecknar l en ej närmare visad anordning för cirkulation av ett värme- utväxlingsmedium, t ex en vätska med nedsatt fryspunkt,genom ett på botten av en sjö nedlagt rörsystem 2. Sjövattnets temperatur kan vara ca +2°C, medan vätskan med nedsatt fryspunkt kan ha temperaturen -400.In Fig. 1, 1 denotes a device not shown in more detail for circulating a heat exchange medium, for example a liquid with a reduced freezing point, through a pipe system 2 laid at the bottom of a lake. The temperature of the seawater can be approx. + 2 ° C, while the liquid with reduced freezing point can have a temperature of -400.

Systemet 2 innefattar två parallella rör 3 och 4 mellan vilka ett eller flera värme- växlarrör 5, nedan henämnda huvudrör, är anslutna. Vätskan med nedsatt fryspunkt tillförs under tryck genom röret 3, varefter vätskan strömmar genom rören 5, såsom I ilarna visar vari enom värme u tas av vätskan, så att dennas tem eratur sti er a 8 till ca +l°C vid inträdet i röret 4. Den sålunda utvunna värmen tillvaratas av anordningen 1 på konventionellt sätt, varigenom temperaturen hos vätskan, som lämnar anordningen l,åter sjunker till ca -400.The system 2 comprises two parallel pipes 3 and 4 between which one or more heat exchanger pipes 5, hereinafter referred to as main pipes, are connected. The liquid with reduced freezing point is supplied under pressure through the tube 3, after which the liquid flows through the tubes 5, as shown in the arrows in which heat is taken out of the liquid, so that its temperature rises from 8 to about + 1 ° C upon entering the tube 4. The heat thus obtained is recovered by the device 1 in a conventional manner, whereby the temperature of the liquid leaving the device 1 drops again to about -400.

Ett av huvudrören i tig. 1 visas i detalj i fig. 2. Huvudröret 5 är i ena änden tätande fastsatt mot en ringformig fläns 6 på rörets 3 mantelyta och i andra änden tätande fastsatt mot en ringformig fläns 7 bildad av en utkragad kant på en i rörets 4 mantel upptagen cirkulär öppning 8.One of the main pipes in tig. 1 is shown in detail in Fig. 2. The main tube 5 is at one end sealingly attached to an annular flange 6 on the mantle surface of the tube 3 and at the other end sealingly attached to an annular flange 7 formed by a cantilevered edge on a circular received in the mantle 4 of the tube 4. opening 8.

Huvudröret 5 innehåller fyra inre, med huvudröret S i huvudsak koncentriska rör 9-12.The main tube 5 contains four inner ones, with the main tube S substantially concentric tubes 9-12.

Rörets 3 mantel är försedd med en cirkulär öppning 13, vars kant är utkragad till bildning av en ringformig fläns 14, kring vilket röret 9 är tätande fastsatt.The jacket of the tube 3 is provided with a circular opening 13, the edge of which is cantilevered to form an annular flange 14, around which the tube 9 is sealingly fastened.

Röret 10 är medelst avståndsorgan 15 fastsatt koncentriskt kring röret 9 på något avstånd från rörets 3 mantelyta. Rörets 9 fria ände mynnar på något avstånd från den närbelägna änden hos röret 10, vilken är tillsluten med en ändvägg l6._ Röret ll är tätande fastsatt mot en ringformig fläns 17 på röret 3. Röret 12 är medelst avståndsorgan 18 fastsatt koncentriskt kring röret ll på något avstånd från rörets 3 mantelyta. Rörets 12 närmast röret 4 belägen ände är tillsluten medelst en ändvägg 19, som är belägen på något avstånd från rörets ll fria ände. 7805240-4 Vätska som inkommer till röret 9 genom öppningen l3'i röret 3 strömmar först genom röret 9 och därefter fram och åter genom mellanrummen mellan rören 9-12 och 5, såsom visas med pilar i fig. 2. Härigenom erhålls en kontrollerad temperaturgradient från kontaktytan mellan vatten och den energiupptagande ytan till den kallaste delen i det energiupptagande mediet, varigenom undviks en påfrysning av huvudrörets 5 kon- taktyta med vattnet.The tube 10 is fixed by means of spacers 15 concentrically around the tube 9 at some distance from the circumferential surface of the tube 3. The free end of the tube 9 opens at some distance from the proximal end of the tube 10, which is closed with an end wall 166. The tube 11 is sealingly attached to an annular flange 17 on the tube 3. The tube 12 is fixed concentrically around the tube 11 by means of spacers 18. at some distance from the 3 mantle surface of the pipe. The end of the tube 12 closest to the tube 4 is closed by means of an end wall 19, which is located at some distance from the free end of the tube 11. Liquid entering the tube 9 through the opening 13 in the tube 3 flows first through the tube 9 and then back and forth through the spaces between the tubes 9-12 and 5, as shown by arrows in Fig. 2. This gives a controlled temperature gradient from the contact surface between water and the energy-absorbing surface to the coldest part of the energy-absorbing medium, whereby a freezing of the contact surface of the main pipe 5 with the water is avoided.

Rören 9-12 kan med fördel utgöras av tunnväggiga, billiga plaströr. Endast på huvud- röret 5 behöver man ställa högre krav på diffusionstäthet.The pipes 9-12 can advantageously consist of thin-walled, cheap plastic pipes. Only on the main pipe 5 do higher requirements need to be set for diffusion density.

Proportionerna mellan zonerna A och B, se fig. 2, liksom antalet rör och dessas dimensioner och längder väljes så, att optimal uttemperatur erhålls hos det värme- bärande mediet.The proportions between zones A and B, see Fig. 2, as well as the number of pipes and their dimensions and lengths are chosen so that optimal outlet temperature is obtained for the heat-carrying medium.

Uppfinningen är ej begränsad till den visade utföringsformen, utan ett stort antal modifikationer därav är tänkbara inom ramen för efterföljande patentkrav.The invention is not limited to the embodiment shown, but a large number of modifications thereof are conceivable within the scope of the appended claims.
