Definitions

  • the invention relates to a tube radiator made of several arranged together and together on the hubs connected similar members.
  • Headpieces made from two sheet metal half shells made by Flash butt welding are interconnected.
  • the Head pieces have pipe connecting pieces that with pipes are connected, the pipes being the height of the Determine tube radiators.
  • the tubes are also butt-welded inserted between the head pieces.
  • the individual links are followed by Resistance welding (spot welding with overlapping Spots, similar to roller seam welding) related.
  • the invention has for its object a Tube radiator to develop another one Simplify the manufacturing process and at the same time a minimum overall height of the smallest design is guaranteed.
  • the tube radiator is there thereby consisting of several similar types arranged next to each other Radiator members made from welded sheet metal shells are formed, the sheet metal shells flow openings for the heating medium and hub-shaped contact surfaces Have connection of the same radiator members, the welded sheet metal shells, which the form the smallest design in the area of Pipe connecting pieces have circular openings.
  • All other connections of the tube radiator will also be preferably produced by laser welding, i.e. the Connection of the pipes with the pipe connection piece of the hubs, the attachment of the blind washers as a separation between Forward and reverse and optionally attaching the blind and / or Connection cover is made by laser welding. Also the connecting pieces pointing vertically down are on at the corresponding end pieces by laser welding fixable.
  • the blind disc between the flow and return is not arranged in the end piece for the first time, but lies between the contact surfaces of two end pieces.
  • the blind washer is preferably attached simultaneously with the connection of the two end pieces, between which the blind washer is arranged.
  • the pipe connection pieces are designed so that Connecting the sheet metal shells by the laser in the area only a circular one between the pipe connections Movement must take place. For this are the pipe connection pieces very short, which means that with the smallest design, resulting from the welding of the two sheet metal shells together results in a significantly lower overall height than the previous versions of tube radiators is possible.
  • Fig. 1 shows a tube radiator with several similar radiator members attached to each other 1.1, 1.2, 1.3 to 1.n in the front view.
  • each Radiator element 1.1, 1.2, 1.3 to 1.n consists of two End pieces 2.1, 2.2, 2.3 to 2.n, between which pipes R are arranged.
  • the end pieces 2.1, 2.2, 2.3 to 2.n point at their contact surfaces A flow openings D for the Heating medium.
  • each End piece 2.1, 2.2, 2.3 to 2.n is made of two sheet metal parts 3 welded together by laser welding, so that at the Butt surfaces of the sheet metal parts 3 a circumferential liquid-tight and burr-free weld seam N1 becomes.
  • Each radiator element 1.1, 1.2, 1.3 to 1.n instructs the end pieces 2.1, 2.2, 2.3 to 2.n pipe connection piece 4 (see Fig. 2), the number of which is the number of pipes R to be used corresponds.
  • the pipe connection piece 4 and the pipes R have on their contact surfaces have the same external dimensions and lie against each other in the butt joint on. Between the two is also done by laser welding an all-round, liquid-tight and burr-free Weld seam N2 produced.
  • the radiator elements 1.1, 1.2, 1.3 to 1.n are also with each other by laser welding related.
  • At both end pieces 2.1 of the radiator element 1.1 connection cover 5 are attached by laser welding.
  • At the lower end 2.1 is the 5 on the connection cover Flow V connected and at the upper end 2.1 is that Thermostatic valve screwed into the connection cover.
  • the radiator element 1.n arranged at the other end indicates its bottom end piece 2.n has a connection cover 5 for the return R on and at the upper end piece 2.n a blind cover 6 is attached by laser welding. Between the first radiator element 1.1, which of the Lead V is supplied and the subsequent Radiator member 1.2 is between the lower end pieces 2.1 and 2.2 a blind washer 7 is welded in. This Blind disk 7 is not, as was previously the case, in the interior but is the outside between the two contact surfaces Radiator links of the lower end pieces 2.1 and 2.2 also attached by laser welding.
  • each Radiator element 1.1 has at the end pieces 2.1 in total four pipe connecting pieces 4 and accordingly four pipes R on.
  • the pipe connection piece 4 do not have a straight line Area on, there is only a radius r between them intended. This makes the height of the smallest design of a tube radiator reduced to a minimum.
  • Figure 3 is the smallest design using the example of a three column shown. The fact that at the pipe connection 4 there is no longer a straight line area circular breakthroughs formed.
  • FIG. 5 An end piece in the form of an upper hub 2.1 with a welded blind cover 6 is shown in Figure 4.
  • the blind disk 7 is shown in FIG. 5, illustration a). This is a circular sheet metal part with a area 7.1 offset from the edge, which is the handling facilitates and centering in the flow opening guaranteed.
  • the disc 8 also has one area 8.1 on the edge and an opening 8.2 on in order to flow through the heating medium ensure (Fig. 5, representation b).
  • a tube radiator in which the connections for pre and Point return V / R vertically downwards and on the first and second radiator element 1.1 and 1.2 are arranged in Figure 6 shown.
  • the connecting pieces for flow and return to the lower To weld end pieces 2.1 and 2.2 by laser At the lower end piece 2.1 of the radiator element 1.1 and both end pieces of the other end, not shown arranged radiator element 1.n are for closing the outward flow openings blind cover 6 welded.
  • the thermostat valve T At the upper end piece 2.1 of the radiator element 1.1 is the thermostat valve T via a connection cover 5 connected.
  • connection cover and the blind cover there is no longer any need to weld one Thread ring in the end piece, making for most Embodiments a much more material-saving Manufacturing is guaranteed.
  • a threaded ring e.g. be welded in for nippling. this happens preferably also by laser welding.
