Uppfinnare: A. G. F. Wallgren och K. E. Eyre11. Inventors: A. G. F. Wallgren and K. E. Eyre11.

Foreliggande uppfinning hanfor sig till kylare for forbranningsmotorer, vilka aro sam- mansatta av till en enhet hopbyggda platar, som foretradesvis hava ett korrugerat parti och vilka parvis mellan sig hava mellanrum, som genom oppningar vaxelvis stft i forbin- delse med till- och avlopp Mr de i kylaren varmevaxlande medlen. Uppfinningen avser att astadkomma en kylare av denna art, som forenar ett Mgt varmeutbyte med stor stadga och lag tillverkningskostnad och som dr äg- nad att framstallas i serietillverkning. Detta ernas vasentligen darigenom, att platarnas sidokanter aro uppvikta till relativt platarnas Ovriga partier at samma hall i vinkel forskju- tande flansar, som hava en sadan hOjd Over namnda ovriga partier, att de i grupper om tvd platars flansar Overlappa varandra, varvid platarna inbordes runt sidokanterna forenade svetsfogar Oro forlagda till de genom Overlappningen mot varandra anliggande flanspartierna. The present invention relates to coolers for internal combustion engines, which are composed of plates assembled into a unit, which preferably have a corrugated portion and which in pairs have spaces between them, which through openings are alternately connected in connection with inlet and drain Mr. the heat-exchanging agents in the radiator. The invention intends to provide a cooler of this kind, which combines a high heat exchange with a large charter and legal production cost and which is suitable for production in series production. This is essentially due to the fact that the side edges of the plates are folded up relative to the other parts of the plates at the same hall at angularly offset flanges, which have such a height above the other parts mentioned, that they overlap each other in groups of two plates, the plates being boarded around the side edges united welds Concerns located to the flange portions abutting by the overlap.

Uppfinningen skall nedan narmare beskrivas under hanvisning till a bifogade ritning som exempel visade utforingsformer, varvid Oven andr a uppfinningen kannetecknande egenskaper skola angivas. The invention will be described in more detail below with reference to the embodiments shown by way of example in the accompanying drawing, in which case other features of the invention may be stated.

I fig. 1 visas en enligt uppfinningen utford kylare sedd uppifran. Fig. 1 shows a cooler challenged according to the invention seen from above.

I fig. 2 visas ett parti av kylaren delvis i sektion efter linjeni fig. 1 och i storre skala. Fig. 2 shows a portion of the cooler partly in section along the line in Fig. 1 and on a larger scale.

I fig. 3 visas ett andparti av kylaren i sek- lion cites linjen IIIIII i fig. 1 och i annu storre skala. Fig. 3 shows a duck portion of the cooler in section cites line IIIIII in Fig. 1 and on an even larger scale.

I fig. 4 visas en modifierad utforingsform ay uppfinningen i liknande sektion som fig. 3. Fig. 4 shows a modified embodiment of the invention in a similar section as Fig. 3.

Den a ritningen visade kylaren ar sammansatt av 8.tta platar, generellt betecknade med 10 och i fig. 3 och 4 med 11-18. De hava en avlang form med lampligen avrundade kortsidor och aro i mitten fOrsedda med ett korrugerat parti 19. Korrugeringarna i t-va narliggande platar forltipa 1 vinkel mot varandra. The radiator shown in the drawing is composed of eight plates, generally indicated by 10 and in Figs. 3 and 4 by 11-18. They have an oblong shape with aptly rounded short sides and are in the middle provided with a corrugated portion 19. The corrugations in the two adjacent plates are at an angle to each other.

Platarnas kanter tiro ombojda till at samina hail i vinkel utskjutande flansar, vilken vinkel Or nagot mindre On 90°, sasom antytts vid 20, varvid dessa flansar hava en sadan h8jd, att de i den fardiga kylaren i grupper em Ire platars flansar Overlappa varandra. I platarnas andar finnas oppningar 21 och 22 for de mellan platarna befintliga mellanrummens vaxelvisa anslutning till till- och avlopp for de hada medlen, som passera kylaren. Medan salunda exempelvis platarna 13 ocli 14 i fig. 3 are fastsvetsade vid varandra vid Oppningen 21, tiro dessa platar i oppningen 22 i stallet likaledes genom svetsning fOrbundna med platarna 12 resp. 15. Pa detta satt kommer ankh vartannat mellanrum att -yid kylarens ejia sida stâ i forbindelse Died en anslutningsstuts 23 ftir ett till- eller avlopp och ndsta mellanrum med ett liknande till- eller avlopp f Or den brecividliggande anslutningsstutsen 24. Platparen 12, 13 och 14, 15 som 16, 17 Oro lampligen Oven pa spridda stallen fastsvetsade vid varandra vid kontaktstallena mellan partiets 19 korrugeringar, sasom antytts -vid 36. De mot varandra anliggande flanspartierna av platarna aro tre och tre hopsvetsade med varandra genom somsvetsning. The edges of the plates are then bent to form hil at an angle projecting flanges, which angle Or slightly less On 90 °, as indicated at 20, these flanges having such a height that they in the finished cooler in groups em Ire plates flanges overlap each other. In the spirits of the plates there are openings 21 and 22 for the alternating connection of the spaces between the plates to the inlet and outlet for the had means which pass the cooler. Thus, for example, while the plates 13 and 14 in Fig. 3 are welded together at the opening 21, these plates in the opening 22 in the stable are also connected by welding to the plates 12 and 12, respectively. 15. In this way, every other space will be connected to the outside of the radiator by means of a connecting socket 23 for an inlet or drain and the next space with a similar inlet or drain for the bridge-connecting connection socket 24. The plates 12, 13 and 14, 15 as well as 16, 17 Concerns about the scattered stables are welded together at the contact stalls between the corrugations of the portion 19, as indicated at 36. The abutting flange portions of the plates are three and three welded together by welding.

Hopfogningen av paketet tillgar pa fOlj ande satt: Som ett forsta arbetstempo punktsvetsas platparen 12, 13 och 14, 15 samt 16, 17 parvis vid varandra vid 36. Deras appningarna 22 begransande partier Oro fortfarande fritt atkomliga fran sidorna, varfor svetsningen av dessa partier kan ske med tillhjalp av svetsverktyg, som fran sidorna obehindrat kunna foras mot partierna ifraga. Den kylarens oversida bildande platen 11, som uppbdr gangade kragar 25, 26 mitt for oppningarna 21, 22 och som hava omvikta flansar, som overlappa platens 12 flansar, fastsvetsas sedan vid platparet 12, 13. Dessa tre platars fldnsar kunna sammanfogas utifran medelst svetsverktyg, sâ att en hopsvetsning dem emellan kan ske ge- 2— — nom somsvetsning, sasom antytts vid 27. Nasta operation blir att skjuta dessa tre platar over ett platpar 14, 15, som pa samma satt hopfogas Hied platen 13 genom svetsfogar 28. Samma gEller aven for det sista platparet 16, 17. Vidare hopsvetsas platarna runt oppningarna 21, 22, vilket -vid utfOringsformen enligt fig. 1-3 sker med tillhjalp av svetsverktyg, som aro sa utforda, att de na in i mellanrummen mellan platarna. Den understa platen 18 forenas med platen 17 genom rundgaende somsvetsning vid 29, och slutligen svetsas platarna 17 och 18 runt oppningen 21. Platen 18 Or vid 8ppningarna 21, 22 utatbOjd sasom visas yid 30, 31. The joining of the package is done as follows: As a first working tempo, the plate pairs 12, 13 and 14, 15 and 16, 17 are spot welded to each other in pairs at 36. Their openings 22 adjacent parts are still freely accessible from the sides, so the welding of these parts can be done with the help of welding tools, which from the sides can be passed unhindered towards the parties in question. The top surface of the radiator forming the plate 11, which has raised collars 25, 26 opposite the openings 21, 22 and which has folded flanges which overlap the flanges of the plate 12, is then welded to the plate pair 12, 13. These three plate flanges can be joined together by welding tools. so that a weld can be made between them by 2— - by welding, as indicated at 27. The next operation will be to slide these three plates over a pair of plates 14, 15, which in the same way are joined together Hied plate 13 by welds 28. Same also for the last pair of plates 16, 17. Furthermore, the plates are welded together around the openings 21, 22, which - in the embodiment according to Figs. The bottom plate 18 is joined to the plate 17 by circumferential welding at 29, and finally the plates 17 and 18 are welded around the opening 21. The plates 18 or at the openings 21, 22 are bent out as shown at 30, 31.

Det framgar av ovanstaende att platarna genom sin speciella utformning enligt uppfinningen kunna parvis hopfogas genom svetsningsoperationer, som ge fullt tillforlitliga f o-gar. Platarna 11, 13, 15 aro inbordes lika utforda, likasa platarna 12, 14, 16. It appears from the above that the plates, due to their special design according to the invention, can be joined in pairs by welding operations, which give fully reliable joints. Plates 11, 13, 15 are inboard equally challenging, as are plates 12, 14, 16.

Anslutningsstutsarna 23, 24 aro avsedda att fastgangas i kanaler, som passeras av de resp. medlen. For att darvid dessa stutsar skola vara atkomliga utifran, aro pa kragarna 25, 26 anbragta lostagbara grupper 32, 33, efter vars avlagsnande stutsarna kunna kringvridas med tillhjalp av ett -verktyg, sasom en mej sel. The connection sockets 23, 24 are intended to be fixed in channels which are passed by the resp. the means. In order for these nozzles to be accessible from the outside, detachable groups 32, 33 are arranged on the collars 25, 26, after which the removal nozzles can be rotated by means of a tool, such as a seal.

Utforingsformen enligt fig. 4 skiljer sig frau den foregaende i huvudsak endast dorigenom, att Oppningarna 21, 22 hava fran plat till plat tilltagande diameter. Platarna hava 90° omvikta kantpartier 34 och aro hopsyetsade vid 35. The embodiment according to Fig. 4 differs from the foregoing substantially only in that the openings 21, 22 have from flat to flat increasing diameter. The plates have 90 ° folded edge portions 34 and are sewn together at 35.

Uppfinningen är givetvis icke begransad till de visade utforingsformerna utan kan varieras i rnanga avseenden inom ramen av patentanspraken. The invention is of course not limited to the embodiments shown but can be varied in many respects within the scope of the patent claims.
