- the invention relates to a method for producing an infrared radiator by providing it a twin tube, which has an inner web, the two in the tube longitudinal direction separating running subspaces from each other, introducing a first heating coil into the first Partial space, insertion of a connecting wire or a second heating coil in the second Subspace, connecting the first, lower end of the first heating coil with one by one End face of the twin tube outward power supply, and connecting the second, upper end of the first heating coil with the connecting wire arranged in the second subspace or with the second heating coil arranged in the second partial space.
- the lamp bulb is in the form of a twin tube made of quartz glass, in which two tubular sections by an intermediate web are spatially separated from each other.
- the twin tube is divided into two equal steel sections over its length. Everyone who Both sections of the twin pipe consist of two halves of the room, with each of the four Partial halves a heating coil is arranged.
- the heating coils of each radiator section are connected in series in pairs. Every heating coil is at its free lower end with a connecting wire for the power supply Mistake.
- the electrical connections for each pair of heating coils are connected to a common one Front of the twin pipe over a vacuum-tight squeeze into the two Molybdenum foils are melted out of the twin tube.
- the heating coils of each pair of heating coils are each made using an M-shaped molybdenum wire connected with each other.
- the molybdenum wire engages the top of the Heating coil and is parallel via a first U-shaped bend within the subspace led back to the heating coil close to the lower end.
- the inner tube of the twin tube is drilled out over a length of a few centimeters or milled out. Between the top of the bruise and the bottom of the land bore an incision of a few millimeters remains. Through this incision therethrough the molybdenum wire extends under a second U-shaped bend in the other Subarea where it is connected to the second heating coil. Seen across both rooms the molybdenum wire is thus M-shaped, with a mirror plane running in the inner web. To avoid short circuits, the molybdenum wire is in the area of the heating coils surrounded by a quartz glass capillary tube.
- the heating coils are centered by means of spacers evenly distributed over their length kept within their subspace.
- the heating coil is in the known infrared radiator with great effort in the twin tube introduced, the spacers on the inner walls of the respective subspaces issue.
- the heating coil is subjected to strong mechanical loads. After assembling it is not de-energized, so that there is a risk that it will become humped during operation or their length - and thus the length of the heating zone - changes. This leads to the known Infrared emitters to failures.
- a twin-tube radiator is known from German utility model DE-U1 91 15 621, in which the two heating coils are connected to one another by means of a molybdenum bracket, the molybdenum bracket engages in the respective ends of the heating coils.
- the inner web is proposed remove the twin pipe from the front by milling or drilling.
- the molybdenum bracket is inserted into the slot created in this way and then the front side of the twin tube squeezed together.
- the known method requires processing of the twin tube and the assembly of the molybdenum bracket from the open end out. To make it easier to insert the molybdenum bracket into the heating coil end faces the molybdenum bracket is easily deformable. However, this leads to changes in position when the radiator is used the heating coils.
- twin-tube infrared radiator in the form of a twin tube is in the German Utility model DE-U1 89 13 683 described.
- an infrared heater is created by melting two individual emitters on the face side generated twice the length, the individual radiators can be switched independently of one another are separated from each other by a partition.
