CLASS 17 f: 4/01 INT. CLASS F 25 h PATENT PERIOD FROM 15 FEBRUARY 1957 GRANTED ON 23 FEBRUARY 1961 PUBLISHED ON 25 APRIL 1961 Ans. 1492/11) 57 on 15/2 1957Harlin a drawing A HUET, PARIS, FRANCE Heat exchangers with flanged ribs Priority requested Iran 21 February 1b56 France) ay diametrical flanges on the riiren, which flanges are bent at the same time as the riiren orb. form continuations of each other in the finished loop, which resembles a cylinder with almost continuous viigg.

Vid dylika rorslingor strommar det yttre yarmemedlet i sammanhangande skikt tangs slingans ut- och insida (fig. 3). In the case of such rudder loops, the outer yarm means flows in a coherent layer on the outside and inside of the pliers loop (Fig. 3).

Enligt uppfinningen Or endast yartannat roryary forsett med dylika diametralt motsatLa flansar, vilka kunna luta at samma eller fran det ena flansforsedda riirvarvet till nOsta It motsatta hall. According to the invention, only the second roryary is provided with such diametrically opposite flanges, which can be inclined at the same or from one flanged circumference to the opposite hall.

Uppfinningen beskrives narmare nedan under hanyisning till bifogade ritning. The invention is described in more detail below with reference to the accompanying drawing.

Fig. 1 visar i sidovy en viirmevaxlarslinga med slata Fig. 2 och 2a visa sehematiskt bockningen av ett rOr med diametralt motsatta flansar. Fig. 1 shows in side view a wire exchanger loop with slat Figs. 2 and 2a show seematically the bending of a tube with diametrically opposite flanges.

Fig. 3 visar i sektion en slinga rued flansar enligt en Mind utforingsform. Fig. 3 shows in section a loop of rued flanges according to a Mind embodiment.

Fig. 4 visar en rOrslinga enligt uppfinningen. Fig. 4 shows a pipe loop according to the invention.

Fig. 1 visar en varmevaxlare med en Itanal a, genom vilken ett varmemedel strommar i pilens 13 riktning, varvid varmeutbyte ager rum med ett eller tva varmemedel, som stromma inuti en slinga b, vilken I. ex. utgOres av tya skruvlinjeformade, koaxiella rot.. Fig. 1 shows a heat exchanger with an Itanal a, through which a heating means flows in the direction of the arrow 13, heat exchange taking place with one or two heating means flowing inside a loop b, which I. ex. consists of tya helical, coaxial root ..

Det Or som bekant mojligt att bocka flansforsedda rot. Mir flansarna Oro belagna i det diametrala plan, som Or vinkelratt mot bockningsplanet. Dylik boaning visas i fig. 2 och 2a, dar roret c Or forsett med diametrala, langsga.ende flansarlibret rullas Over hoekningstrissan e, mot vilken det tryekes medelst stodtrissor 11, P. Av fig. 2a framgar, att de diametrala flansarna (11, dm fa plats melIan bockningstrissan e och stodtrissan P. It Or, as is well known, possible to bend flanged root. Mir flanges Oro coated in the diametrical plane, which Or perpendicular to the bending plane. Such a bore is shown in Figs. 2 and 2a, where the rudder c Or provided with diametrical, longitudinal flange rib is rolled over the corner pulley e, against which it is pressed by means of support pulleys 11, P. Fig. 2a shows that the diametrical flanges (11, dm get space between the bending pulley e and the pulley P.

I fig. 3 visas hur ett ror c fOrsett med diametrala, langsgaende flansar (11, dm formats till en rOrslinga. Mr man bar en slinga, som Midas av tva koaxiella rOr, kan bockningen ay roret e och av det rOr g, som befinner sig inuti (left a, she samtidigt Over bockningstrissan e. Fig. 3 shows how a rudder c provided with diametrical, longitudinal flanges (11, dm formed into a rudder loop. sig inside (left a, she at the same time Over the bending pulley e.

Om man yill Ora en slinga med tatare vary, kan man minska filinsarnas d', dm bredd och till och med utesluta den ena Hansen varvid flansarna komma i kontakt med den slata nedre delen av det oyanfor belagna rOryarvet. If you want to make a loop with a tatter vary, you can reduce the width of the fil's d ', dm and even exclude one Hansen, whereby the flanges come into contact with the smooth lower part of the oyanfor coated rOry heritage.

Enligt uppfinningen anbringar man emellertid Hansen endast pa vissa sektioner av roret c, varvid detta forblir gall: daremellan, sa att man erhaller en slinga, hos vilken Tartannat vary Or for sett med flansar och de mellanliggande varven Oro slata. Detta askadliggtires i fig. 4 for varven 1, 2, 3, 4, 5. Varvets 1 diametrala flansar (11, dm Oro efter bockningen krokta shsont visas ph figuren, sh att flansen dm blir belagen i ett plan, som ungefar tangerar den narmast oyanfor belagna delen av rorvarvet nr 2. Sasom framgar ay figuren luta flansarna (11, dm onwaxlande ht olika hit% ht ena ballet hos riirvarv nr 1, at andra hos vary nr 3 osv., sa att en verksam bestrykning ay de sliita roryarven 2, 4 osv. erhalles. According to the invention, however, Hansen is applied only to certain sections of the tube c, this remaining bile: in between, so that a loop is obtained, in which Tartannat varies or for seen with flanges and the intermediate turns Oro slata. This is not shown in Fig. 4 for the turns 1, 2, 3, 4, 5. The diametrical flanges of the turn 1 (11, dm. oyanfor covered part of the rudder yard no. 2. As can be seen from the figure, the flanges (11, dm unwaxande ht different hit% ht one ballet at rudder turn no. 1, that others at vary no. 3, etc., , 4, etc. are obtained.

FOr att underlhtta flansarnas dl, dm bock-fling i den onskade riktningen anordnar man urtagningar h vid olika stallen pa Hansen. To facilitate the flanges of the flanges, ie bend-flake in the desired direction, recesses are arranged at the various stables on Hansen.
