Description

469 9 10 15 20 25 30 35 ...Å- 2 2 uppvärmt vatten från kylkanalerna i motorblocket till rören i värmeväxlarpaketet. För det andra är förbindningen mellan rör och anslutningsplatta svag. För det tredje skapar det nödvändiga avståndet mellan hålraderna i an- slutningsplattorna en spalt 27 genom värmeväxlarpaketet. I denna spalt sker ingen värmeöverföring. Av praktiska skäl låter man dock lamellaggregaten sträcka sig även över spalten, vilket skapar ett onödigt tryckfall för den för- biströmmande luften. i Huvudändamàlet med uppfinningen är att undanröja de ovan angivna nackdelarna hos den kända kylaren. 469 9 10 15 20 25 30 35 ... Å- 2 2 heated water from the cooling ducts in the engine block to the pipes in the heat exchanger package. Second is the connection between pipe and connection plate weak. For the third creates the necessary distance between the rows of holes in the the closing plates a gap 27 through the heat exchanger package. IN in this column no heat transfer takes place. For practical reasons however, the lamella assemblies are also allowed to extend over gap, which creates an unnecessary pressure drop for the the flowing air. in The main object of the invention is to eliminate them the above disadvantages of the known radiator.

Ett ytterligare ändamål är att åstadkomma en kylare som är effektivare än den kända kylaren och som samtidigt tar mindre plats i motorrummet.A further object is to provide a cooler which is more efficient than the known radiator and which at the same time takes up less space in the engine compartment.

Dessa ändamål uppnås med en fordonskylare av inled- ningsvis nämnt slag, vilken kännetecknas av att anslut- ningsplattorna vid varje hål har en från tanken utskjutan- de anslutningsstos; att rörens ändar har ett vidgat parti för mottagning av motsvarande anslutningsstos på anslut- ningsplattorna; och att rören i den första raden ligger tätt intill motsvarande rör i den andra raden utmed det rörparti som ligger mellan de vidgade partierna av röret.These objects are achieved with a vehicle radiator of initial mentioned type, which is characterized by the The plate at each hole has one projecting from the tank. the connection sockets; that the ends of the tubes have a widened portion for receiving the corresponding connection socket on the the plates; and that the pipes are in the first row close to the corresponding pipe in the second row along it pipe portion located between the widened portions of the pipe.

En fördel med kylaren enligt uppfinningen är att för- bindningen mellan värmeväxlarpaketet och anslutnings- plattorna kan göras starkare tack vare anslutningsstosar- nas inskjutning i rörändarna. Styrkan i konstruktionen kan ökas ytterligare om rören i den första raden förbindes med motsvarande rör i den andra raden i de rörpartier i res- pektive rad som anligger mot varandra.An advantage of the cooler according to the invention is that the connection between the heat exchanger package and the connection the plates can be made stronger thanks to the connection insertion into the pipe ends. The strength of the construction can further increased if the pipes in the first row are connected to corresponding pipes in the second row of the pipe sections in respective rows abutting each other.

En annan fördel med kylaren enligt uppfinningen är att rörets ände alltid hamnar i samma plan som motsvarande ändar på de andra rören. Detta ger en kylarkonstruktion med ett väldefinierat avstånd mellan anslutningsplattorna även om de platta rören före vidgningen av deras ändar har olika längd. Anledningen till detta är att vidgningen av rörändarna kortar röret från exempelvis 500 mm till 498 mm. Eventuella skillnader i ursprunglig rörlängd eli- 10 15 20 25 30 35 3 mineras under vidgningen av rörändarna. De vidgade par- tierna "tar upp" dessa skillnader i rörlängd och säker- ställer samma längd på de färdigbearbetade rören. Upp- finningen kommer nu att beskrivas närmare nedan med hjälp av ett utföringsexempel under hänvisning till medföljande ritningar.Another advantage of the radiator according to the invention is that the end of the pipe always ends up in the same plane as the corresponding one ends of the other tubes. This provides a radiator design with a well-defined distance between the connection plates even if the flat tubes before the widening of their ends have different length. The reason for this is the widening of the pipe ends shorten the pipe from, for example, 500 mm to 498 mm. Any differences in original pipe length eli- 10 15 20 25 30 35 3 mined during the widening of the pipe ends. The expanded par- "address" these differences in pipe length and safety sets the same length of the finished pipes. Up- The finding will now be described in more detail below with help of an embodiment with reference to the accompanying drawings.

Pig. 2 visar i sprängvy och schematiskt en fordons- kylare enligt uppfinningen.Pig. 2 shows in exploded view and schematically a vehicle cooler according to the invention.

I fig 2 visas ett värmeväxlarpaket 1 till en fordons- kylare framställd enligt uppfinningen. Värmeväxlarpaketet omfattar i likhet med värmeväxlarpaketet i ovan beskrivna ~ konventionella fordonskylare två stycken anslutningsplat- tor 2, 3 varav den ena anslutningsplattan 2 utgör en av begränsningsytorna av en inloppstank (inte visad), medan den andra anslutningsplattan 3 utgör en av begränsnings- ytorna av en utloppstank (inte visad). Mellan anslut- ningsplattorna 2, 3 är två väsentligen parallella rader av platta rör 9 insatta och anordnade att avkyla och leda det strömmande vattnet från den ena tanken till den andra.Fig. 2 shows a heat exchanger package 1 for a vehicle cooler manufactured according to the invention. The heat exchanger package comprises, like the heat exchanger package in ~ described above conventional vehicle radiators two connecting plates tor 2, 3 of which one connection plate 2 constitutes one of the confinement surfaces of an inlet tank (not shown), while the second connection plate 3 constitutes one of the limiting the surfaces of an outlet tank (not shown). Between connections plates 2, 3 are two substantially parallel rows of flat tube 9 inserted and arranged to cool and guide it flowing the water from one tank to the other.

Anslutningsplattorna är försedda med två i anslutnings- plattans längdriktning löpande, väsentligen parallella rader av hål 5, vilka i tvär- resp längdriktningen är be- lägna på avstånd från varandra. I anslutning till hålen är s k stosar 6 riktade ut från anslutningsplattan i riktning mot de mellan plattorna belägna rören. De mellan plattorna anordnade platta rören är utvidgade vid sina respektive ändpartier 7 för åstadkommande av en större inlopps- och utloppsarea till resp från värmeväxlarpaketet 1 och åstad- kommande av en mjukare övergång mellan inlopps- resp ut- loppstankarna och rören. Rörändarna har emellertid mindre dimension än det tillplattade röret i övrigt sett i rörets huvudplan. Rörändarna vidgas så mycket och ges en sådan till stosarna anpassad form att rörändarna kan skjutas på stosarna och lödas fast på dessa för att bilda ett tätt och stabilt förband mellan anslutningsplatta och rören.The connection plates are provided with two in the connection the longitudinal direction of the plate continuously, substantially parallel rows of holes 5, which in the transverse and longitudinal directions are spaced apart. Adjacent to the holes are so-called sockets 6 directed out from the connection plate in the direction against the pipes located between the plates. Those between the plates arranged flat pipes are widened at their respective end portions 7 to provide a larger inlet and outlet area to and from the heat exchanger package 1, respectively, and coming of a smoother transition between inlet and outlet the flue tanks and pipes. However, the pipe ends have smaller ones dimension than the flattened pipe otherwise seen in the pipe master plan. The pipe ends are widened so much and given one shape adapted to the sockets that the pipe ends can be pushed on the sockets and soldered to them to form a tight and stable connection between the connection plate and the pipes.

Rören i den ena raden anligger mot röret i den andra raden 469 9'š2 10 15 20 25 30 35 4 utmed väsentligen rörens hela platta parti. Företrädesvis är rören hoplödda vid detta anliggningsparti 10 för att skapa en ytterligare förbättring av konstruktionens sta- bilitet och styrka.The tubes in one row abut the tube in the other row 469 9'š2 10 15 20 25 30 35 4 along substantially the entire flat portion of the tubes. Preferably the tubes are soldered together at this abutment portion 10 to create a further improvement of the construction stability and strength.

Växelvis med rören 9 i respektive rad är lamellaggre- gat 8 anordnade, vilka är av konventionell typ, för för- biledning av strömmande luft som utnyttjas för kylning av den i rören befintliga vätskan.Alternately with the tubes 9 in the respective row, the lamella 8 are provided, which are of the conventional type, for formation of flowing air used for cooling of the liquid present in the tubes.

Den ovan beskrivna utföringsformen i enlighet med föreliggande uppfinning har flera fördelar framför förut kända fordonskylare.The above-described embodiment according to The present invention has several advantages over the foregoing known vehicle coolers.

Anliggningen mellan de i tvärriktningen bredvid var- andra anordnade rören utmed väsentligen hela deras längd ger fordonskylaren en mindre tjocklek, vilket enligt be- räkningar ger minskad totalvikt på ca 12% till följd av minskad materialmängd i tank, anslutningsplatta och lamellaggregat. Tryckfallet på den förbiströmmande luften minskar vidare med ca 18% till följd av den minskade tjockleken.The abutment between those in the transverse direction next to each other arranged pipes along substantially their entire length gives the vehicle radiator a smaller thickness, which according to bills give a reduced total weight of about 12% due to reduced amount of material in tank, connection plate and lamella assembly. The pressure drop on the overflowing air decreases further by about 18% as a result of the decrease the thickness.

Utformningen av anslutningsplattor med stosar leder till minskat tryckfall på det strömmande vattnet, eftersom rören inte sticker in i tanken. Förbindningen mellan rör- ändarna och stosarna förstärks också eftersom lödning kan genomföras på en större yta.The design of connection plates with sockets leads to reduced pressure drop on the flowing water, because the pipes do not protrude into the tank. The connection between the ends and sockets are also reinforced as soldering can carried out on a larger surface.
