"Infrared Sträier"

The invention relates to an infrared heater with two-sided electrical connection for a heating conductor, which is in a cladding tube made of quartz glass »quartz, a glass that is difficult to melt or the like * is arranged.

are electrically heated infrared emitters made of quartz glass, Quurssgut. or a glass with a high melting point belc & omt? These infrared heaters, a wire or a wire spiral as a heating conductor benatzt ₀ adversely affect these infrared radiators that age for a longer operation of the radiator, in particular in the vertical £, the heating conductor sag, and arises as a result not a uniform Slühbild. As a result of the sagging fcaäiu.der .., the companion lightly burned through

Are infrared emitters also known _? in which the heat conductor parts are arranged in capillaries which are in a quartz "glass" or QuarsguttföiMi & ärper ". These infrared radiators have the disadvantage that they have a large mass and that the whole body does not warm up evenly, so that tensions occur which cause anIaS to hoist and, in severe cases, even cause the infrared radiation to burst. In addition, due to the relatively large mass of the radiator, there is a risk that sausage congestion will form, which will have a negative effect on the heating conductor parts:

Apart from thisea laefe.teilea the production requires ®i such an infrared emitter with capillaries a raise technical effort. "

The properties of the infrared radiators described above and shown in Figures 1-3 can be improved by the fact that the lamella, or the body with lamellar-like wings around its baw. its longitudinal axis is twisted. As an additional advantage, this results in an improvement in the positional stability of the heat conductor _t so that even if the infrared heater In is used for a very long time. vertical position, a collapse or irreversible vibration of the spiral-shaped heat conductor is avoided with absolute certainty, even with infrared radiators of about 1 πι length and more.

from heating coils with different inclinations that go through the spiral lamellae are separated from each other, a uniform distribution of radiation in all directions is also here ■ causes »

Me arrangement according to the invention of a twisted or untwisted lamella or a twisted or untwisted body with a lamella type organ. Wings within the cladding tube of an infrared radiator have proven particularly effective oei infrared radiators, whose cladding tube preferably has a clear width of 6 mm * in which a lamella of about 0.8-1.5 mm J3iclce with a small distance from the inner cladding tube wall incorporated <iat When using twisted fins haw.- of twisted bodies "jjj.it lamellar wings is the twist selects so- 'that, for example per 3 -. 5 cm length of the blade or of the blade-like body one turn is available Der The heating conductor is fed, for example, in such a way that the infrared heater has an output of about 4-7 watts / cm of the envelope tube surface.

In the. FIGS. 4 and 5 show an exemplary embodiment of the invention with a twisted lamella. FIG. 5 shows a ^ transverse; section through & s infrared radiator according to Figure 4. In Figures 4 and 5, the reference number 1 is assigned to the cladding tube. The lamella 2, which is twisted about its longitudinal axis, is arranged in this cladding tube with little clearance. chambers 3 »4 is the heat conductor 5 - designed« The heating conductor is electrically fed via,: the connection ends 6, 7, 6, 9. Even with the infrared radiators with a twisted lamella or a twisted body with lamellar blades, an electrical mode of operation, as already indicated above, is possible.
