Abstract

A heat-exchanger has a tubular body comprising first and second elongated sheets extending parallel inside the tube. The sheets are connected to each other along the opposite longitudinal edges of each sheet respectively, and along first and second seams extending parallel to the edges. The sheets, edges and seams delimit three parallel channels in the length direction of sheets. A heat-exchanger comprises a tube (1) for conducting a first medium that is to be cooled; and a tubular body arranged inside the tube for conducting a cooling medium. The tubular body comprises first and second elongated sheets (11, 12) extending in parallel inside the tube. The sheets are connected to each other along the opposite longitudinal edges (28, 29) of each sheet respectively, and along first and second seams (16, 17). The seams extend in parallel to the edges. The sheets, edges, and seams delimit three parallel channels (13, 14, 15) in the length direction of the sheets.

Description

Uppfinningens bakgrund Det är välkänt att ytans storlek på ett värmeöverförande element är en väsentlig faktor för konvektionen. Background of the Invention It is well known that the size of the surface of a heat transfer element is an essential factor for convection.
Rörförångare förses ofta med flänsar eller dylikt på utsidan och/eller insidan för att öka konvektionen mellan rör och media. Pipe evaporators are often fitted with flanges or the like on the outside and / or inside to increase the convection between pipes and media.
I rörförångare för livsmedel används mestadels släta ämnesrör för värmeöverföring som klarar de hygieniska kravet att vara lättdiskat. In pipe evaporators for food, smooth blank pipes are mostly used for heat transfer that meet the hygienic requirement to be easily washed.
Uppfinningens ändamål och viktigaste kännetecken Ändamålet med uppfinningen är att åstadkomma ett rörelement med stor ut- och in-vändig yta och som uppfyller hygieniska krav som ställs vid värmeväxling av livsmedel. The object and most important features of the invention The object of the invention is to provide a tubular element with a large outer and inner surface and which meets hygienic requirements set for heat exchange of foodstuffs.
Detta är löst i uppfinningen genom att två plana långsmala plåtar sammanfogats och formats till ett rörliknande element bestående av tre parallella kanaler som i ändarna övergår till en cylindrisk kanal. This is solved in the invention by joining two flat elongate plates and forming them into a tube-like element consisting of three parallel channels which at the ends merge into a cylindrical channel.
Formningen är gjord så att, om elementet placeras i ett rör med samma innerdiameter som elementets maximala yttermått, så är utrymmet för media utanför och i elementet lika stora. The molding is made so that, if the element is placed in a tube with the same inner diameter as the maximum outer dimension of the element, then the space for media outside and inside the element is equal.
Ritning med beskrivning Fig. 1 visar uppfiningen två projektioner samt snitten a-a och b-b.Drawing with description Fig. 1 shows the invention two projections and sections a-a and b-b.
Fig.2 visar uppfinningen vid snitt a-a placerad i ett rör, streckad linje, med samma innerdiameter som uppfinningens maximala mått.Fig. 2 shows the invention at sections a-a placed in a tube, dashed line, with the same inner diameter as the maximum dimensions of the invention.
Uppfinningen är tillverkad av två plana, långsmala plåtar med avsmalnande ändar. Plåtarna är sammanfogade i överkant (1) och i underkant (2) efter hela dess längd samt sammanfogade med två sömmar (3) parallellt och på samma avstånd från kanterna. Sömmarna (3) slutar där avsmalningarna mot ändarna börjar. The invention is made of two flat, elongate plates with tapered ends. The plates are joined at the top (1) and at the bottom (2) along their entire length and joined at two seams (3) in parallel and at the same distance from the edges. The seams (3) end where the taper towards the ends begins.
Det hopfogade ämnet är sedan format så att tre kanaler enligt snitt a-a bildas där sömmarna (3) finns och som övergår till en kanal med cirkulärt tvärsnitt i ämnets avsmalnande ändar enligt snitt b-b. The joined blank is then shaped so that three channels according to section a-a are formed where the seams (3) are located and which merge into a channel with a circular cross-section in the tapered ends of the blank according to section b-b.
Vid beräkning av uppfinningen överförd värmemängd med ekvationen Image available on "Original document" där A = den värmeöverförande ytan (m<2>), tl= gasen eller vätskans temperatur på något avstånd från den värmeöverförande ytan (°C), t2= den värmeöverförande ytans temperatur (°C), a = värmeövergångstalet W/ m2 °C som är en funktion av de strömmand mediets tillstånd och hastighet, så kan arian (A) användas både för beräkning av värmeöverföring från eller till elementet. When calculating the invention heat transfer with the equation Image available on "Original document" where A = the heat transfer surface (m <2>), tl = the gas or liquid temperature at some distance from the heat transfer surface (° C), t2 = the heat transfer surface temperature (° C), a = heat transfer coefficient W / m2 ° C which is a function of the state and velocity of the flowing medium, then the aria (A) can be used both for calculating heat transfer from or to the element.
