Definitions
- the invention relates to a radiator, in particular Tube radiator made of several arranged and Similar links connected together at the hubs according to the preamble of the first claim.
- the flow openings are provided Headpieces made from 2 half-shells made by Flash butt welding can be connected to each other.
- the Head pieces have pipe connection 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) connected.
- the pipe connection pieces of the individual half-shells are formed relatively long so that the laser both a linear as well as a semicircular movement must execute. Furthermore, the long Pipe connection piece a very small height of the smallest Design not possible.
- the invention has for its object a Tube radiator to develop another one Simplifying the manufacturing process and at the same time a minimum overall height of the smallest design is guaranteed.
- the tube radiator is there known manner from several arranged together and like connected together at the hubs Links consisting of end pieces between them Pipes are welded in, the end pieces from welded together without burrs by laser welding Half shells are formed. According to the invention, too the pipes with the pipe connection piece and the individual Links joined together by laser welding. Also all other connections of the tube radiator manufactured for the first time by laser welding, i.e. the Connection of the pipes with the pipe connection piece of the hubs, the connection of the individual links, the attachment of the Blind washers as separation between forward and return and optionally attaching the blind and / or connection cover is done by laser welding.
- the vertically down Pointing connecting pieces are on the corresponding End pieces can be attached by laser welding.
- the attachment of the Blind disk is preferably carried out simultaneously with the Connect the two end pieces, between which the Blind disc is arranged.
- To the parallelism of the Ensuring radiator links is also in the Blind plate opposite side of the radiator a breakthrough between the end pieces Disc arranged which is the same sheet thickness as that Has dummy disc. This disc is also preferred simultaneously with the laser welding of the end pieces connected to this.
- the pipe connecting pieces of the end pieces are designed that to connect the sheet metal shells by the laser in Area between the pipe connection piece only one circular movement must take place.
- the Pipe connection piece very short, which in the smallest design, which results from welding the both sheet metal shells results in a much smaller one Height than in 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 faces 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 tubes R have on their contact surfaces have the same external dimensions and lie against each other in the butt joint on. Between them 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 connected. At both end pieces 2.1 of the radiator element 1.1 connection cover 5 are attached by laser welding.
- connection cover 5 Flow V connected and at the upper end piece 2.1 that is Thermostatic valve screwed into the connection cover.
- the radiator element 1.n arranged at the other end indicates its bottom end piece 2.n 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.
- FIG 2 is a radiator 1.1 in the form of a Four-pillar shown in side view.
- 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 rings are Recognize contact surfaces A. Via the flow openings D the transport of the heating medium by one Radiator section to the next radiator section guaranteed.
- the pipe connection piece 4 have no 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 no rectilinear area is more circular breakthroughs formed. Through this novel Shape can change the overall height compared to conventional radiators be reduced by a few centimeters.
- the tin shells are the smallest in their circumference welded together. For the manufacture of tubular radiators Larger designs, these hollow bodies are e.g. in the Partition plane T divided, and between the connecting pieces of these two parts (end pieces) through the pipes R. Laser welding welded in.
- the blind disk 7 is shown in FIG. 5, illustration a).
- the disc 8 also has one area 8.1 on the edge and an opening 8.2 to the flow openings of the heating medium there too ensure (Fig. 5, representation b).
- a tube radiator in which the connections for pre and Point the 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 on.
- At the upper end piece 2.1 of the radiator element 1.1 is the thermostatic valve T via a connection cover 5 connected.
- connection cover and the blind cover With the welding of the connection cover and the blind cover the usual welding of one is no longer necessary 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.
