Radiator.

The present invention relates to a radiator, whose members consist of two half-shells, have a weld seam on the circumference and are mounted next to each other Convection shafts with the room wall as a boundary form, while their outer surfaces form a radiation plate represent.

Radiator members of the type mentioned are known. They consist of two individual half-shells, which are one circumferential weld seam are connected to each other. It

there is also the disadvantage that at higher pressures The weld seams cannot withstand inside the radiator * A disadvantage was also the requirement special devices with which the exact fit of the two half-shells during the Schujeißvorgangs must be ensured what affects production costs.

The object of the invention is to provide the weak parts of the known Avoid executions, so that in addition to the economic benefit, an increase in the thermal efficiency and a very good heat transfer from the heating medium to the room air is achieved. The solution This task uird is seen in the fact that the two half-shells of the radiator are a coherent standing part form, which are folded up around a symmetrically arranged bending edge and welded to their contact edges.

These measures result in a quick and cheap manufacturing. The welded radiator members have a great strength even against high Operating pressures. As a result of the shortening of the weld seam, the material and time required are compared to the conventional one Radiator decreased.

In an embodiment of the invention, have; the stampings Crimps on after the half-shells have been folded be welded.

In this way there are cavities for the circulation of the Heating medium formed. At the same time, the strength of the shape is increased of the radiator so that you can get by with lower material thicknesses. The beads can be in one Production process, introduced the stamped part that their attachment after the one-time creation of the tool does not require any additional effort requires.

According to the invention it is also provided that the half-shells with shallow bulges to form narrow cavities and a deep bulge to form a wide cavity are provided.

As a result of this feature, the radiator members are given a general T-shape so that when they are put together large air ducts with large surfaces to form a radiator form, whereby a good heat transfer is ensured.

It is also very advantageous that the half-shells on

their circumferential edge next to the flanges with indentations bzLJ. Inlets are provided.

This ensures that the individual radiator elements when producing the same, especially when molding and when there is an excess, no excessive stress on the corners so that relatively cheap material can be used. It doesn't have to be from Hand autogenous re-welded to the radiator to be sealed, as in the absence of such crankings would be the case.

According to the invention, the radiators consist of individual ones Limbs, the composite radiator limbs a closed radiation surface in a manner known per se form, which adjoin one another at obtuse angles Outer walls of the wide cavities is composed.

In this version are the outer walls of the wide cavities not perpendicular to the connecting planes between the individual radiator members, like that that the result is a particularly large, flat ribbed surface. This causes surface enlargement a high thermal efficiency. At the same time you achieve one

enlarged radiation angle, so that the heat faster is distributed in the room. In this context it is advantageous that stepping forward through the crankings the flanges and thus a receding of the radiation plate is effected, so that there is an additional focus of the radiation.

It is also important that the back of the wide cavities, the side of the narrow one. Cavities and the Raurnwand in a known manner convection shafts form.

Due to the design with the help of the beads are included Channels or chimneys formed, which a particularly high heat utilization and a rapid circulation of the heated Allow air flow. Again, one is proportionate Large, quasi-ribbed surface available, with concentric heat radiation inwards, which gives off heat still improved.

In a further embodiment of the invention, the volume of the individual narrow cavities lower than that of the wide cavity. . "" .--

it is therefore mainly used in the front width Cavity, so that its heat emission is greatly increased. Overall, this measure contributes to the fact that one is with very small amounts of heating medium get by that who * relatively short heating times are possible, that despite the lower lijärme sales among the narrow ones Cavities, a high air velocity results.

Further features according to the invention and special advantages They are included in the following description based on the drawing explained in more detail. However, the invention is not intended to be restricted to the exemplary embodiment shown.

surface design of a radiator according to the invention.

The heater according to the invention shown in the drawing consists of a stamped part, which is shown in Figure 1 in plan view. It contains pressed-in narrow ones Beads 1 and wider beads 2 and is designed so that it can be folded up around a bending edge 3 can. The two halves of the folded part are denoted by 15 and 16. The punched part is on flanges 14 with openings 17 at both ends.

The folded stamped part is held together with weld seams k and on the flanges 14 with weld seams 5. Sieves 1 and 2 are spot welded. It can be seen in particular from FIG. 2 that narrow cavities 6 and 7 and a wide cavity 8 are formed when it is folded up. The heating medium flows through these cavities 6-8. In the illustrated embodiment, two double hollow spaces 6 and 7 are provided, but it would easily be possible to provide heating element members with one or more than two small hollow spaces.

The ualumen of the wide cavity 8 is larger than that

of the cavities 6 and 7. The outer walls 9 of the cavity 8 are not at right angles to the connecting plane of the radiator element, but make a small angle with it. The assembled radiator members thereby result a radiation surface, the arrangement of which is shown in FIG is shown schematically. The radiator therefore preferably radiates into the interior of the room in arrow direction 10 Heat from, and because of the angularly adjoining outer surfaces 9 with a widened radiation angle.

For the manufacture of radiator members it is important to that at points 11 and 12 next to the flanges 14 a Retraction or cranking 13 is provided, whereby the corner stress during Ueforming and Uwelding is decreased. Without this offset 13, the stress on the material would be too great because of the The material is then spread out into the region of the flanges 14 would, .um in a sense van der Einkröpf

13 to take away.

The bend 13 still allows the flanges

14 step forward a little above and below or the radiation plate to allow the composite outer surfaces 9 to step back somewhat in between, so that a bundling of the

Thermal radiation towards the interior of the room is achieved.

Bsi dam radiators according to the invention, the advantages of radiant heating are also connected to those of convection heating. The; Rear side of the wide cavities 8 which Seitenuände the schraalBn ■ cavities 6, 7 and the form ¹ Raumuand 2G namely Konvektionsschächte together, denoted in Figure 2 by 25 and 26th The heat is radiated concentrically into these convection shafts 25, -26, namely in the direction of the arrow 18 from the cavities 6, 7 and in the direction of the arrows 27, 28 from the rear of the cavity 8. As a result, a very good heat transfer is achieved from the heating medium to the room air, with the convection shafts 25, 26 having the shape of smooth-edged channels, so that a relatively high air velocity is created.

As indicated schematically in Figure 2, in the Arrow directions 30 and 31 still further radiator members scheduled merden. "
