Definitions
- the invention relates to a short-wave infrared radiator with at least one infrared radiator, which has a cladding tube which encloses a heating coil in a vacuum-tight manner electrical connection is provided via a pinch formed on the end face of the cladding tube, in which a molybdenum foil is melted, on the connection side from the cladding tube is brought out.
- Infrared radiators of this type are used, among other things, for polymerizing plastics or used for curing paints or drying paints. They are floodlights known, with a cladding tube that meanders or spirals in a radiation plane is bent. The cladding tube surrounds a heating coil with connections for an electrical Power supply is connected. The connections are usually on the front of the Cladding tube over flat bruises, in which a molybdenum film is melted is led out of the cladding tube.
- twin tubes are also known, in which a cladding tube has a longitudinal axis dividing central web divided into two parallel subspaces is, wherein a heating coil is usually arranged in both sub-rooms.
- the two Heating coils are in the area of one end of the twin tube with a contact pin connected, which protrudes through the central web.
- the electrical connections for the Heating coils are usually on one and the same end face of the twin tube Bruises brought out.
- the production of the known short-wave infrared radiators is relatively complex.
- the Areas around the electrical connections are unheated, which results in a flat arrangement several surface emitters leads to a reduction in the power density and in particular for applications of the floodlights in difficult to access or confined spaces can be disadvantageous, in particular the bulky electrical connection can be a hindrance can.
- the invention is therefore based on the object of a short-wave infrared radiator specify with high power density, which is easy to manufacture and easy to handle.
- the task is based on the short-wave infrared radiator described above solved according to the invention in that several interconnected infrared radiators forming a common radiation plane adjacent and parallel to each other are arranged, the connection-side end of the cladding tubes each with respect to the radiation plane is angled.
- a plurality of cladding tubes are arranged parallel to one another and next to one another.
- the cladding tubes lie directly next to one another without any space.
- Heating coils are roughly on a common level that defines the radiation level.
- the main radiation direction of the surface radiator runs perpendicular to the radiation plane.
- connection-side end of the cladding tube is in relation to the radiation plane angled. At least one becomes from the connection-side end of the cladding tube of the electrical connections for the heating coil.
- the cladding tubes are usually straight, at least in the radiation plane. However, they can also be curved in the radiation plane. The only essential thing is that several cladding tubes are arranged parallel to each other.
- the arrangement and shape of the cladding tubes according to the invention results in an infrared surface radiator in the form of an angle, one leg of the angle parallel to the radiation plane runs, and over the other leg, the electrical connections for the heating coils are led.
- By bending the ends of the cladding tubes on the connection side on the one hand short unheated partial lengths (of the cladding tubes) are realized in the radiation level, because the heating coils can each be brought close to the bend. This leads to a small unirradiated area and high power densities. And secondly become the bulky and rigid connecting wires for the electrical connection from the radiation level taken out what they are handling in particular the area heater difficult to reach places.
- the area heater shown in Figure 1 comprises two quartz glass twin tubes 1, which are lined up side by side, without spacing, parallel to each other.
- the twin tubes 1 are divided by a central web 2 into two sub-rooms each for receiving a heating coil 3.
- the connection-side end 4 of the surface radiator can be clearly seen from the front view according to FIG. This is angled upwards with respect to the radiation plane 14.
- the electrical connection for the heating coils 3 is made via the same end face (see also Figures 2 and 3) of the twin-tube radiator 1 via a pinch 5 into which a molybdenum film 6 is melted down. Therefore all electrical connection wires are also led out through one (connection-side) side of the panel radiator.
- the terminal-side bruises 5 each open into a cavity, which follows is referred to as tulip 7.
- the molybdenum film 6 with electrical is on both sides of the Qucheschung 5 Connection wires 8, 9 connected.
- the lead wire 8 is inside the tulip 7 out and covered by a strand 10 above the tulip.
- the two heating coils 3 within a twin tube 1 are in the area of the connection side End 4 facing away from end 11 of the surface radiator by a contact pin 12, which projects through the central web 2, is electrically connected to one another. Also the end 11 of each Twin tube radiator 1 is closed in a vacuum-tight manner by means of a pinch 13. Are there the adjacent bruises 11 in the form of a continuous web 13, the connects the two twin tubes 1 together.
- All (four) heating coils 3 are electrically connected in series in the exemplary embodiment.
- the radiation level of the surface radiator is indicated by a dashed line 14; it extends perpendicular to the leaf plane.
- the main emission direction is shown by the direction arrow 15.
- the top of the quartz glass twin tubes 1 is - except in the area of the bruises - covered with a gold reflector 16, which is shown in FIGS is symbolized by a dotted line.
- connection-side end 4 of the respective twin tubes 1 or of the surface radiator is bent upward by an angle of 90 ° with respect to the radiation plane 14 and opposite to the main emission light 15.
- the bend is carried out in the area of the film melting, as a result of which the melted-in molybdenum film 6 is bent upwards by 90 °.
- the bend is not drawn to scale, but rather is shown enlarged. Due to the bend, the heating coils 3 extend almost over the entire radiation level 14, so that only narrow unheated surfaces result in the area of the connection-side end 4 of the surface radiator. At least about half of the pinch 5 is omitted on an unheated surface.
- the fact that the electrical connections are bent upwards makes the heater easier to handle. Even small and angled rooms are easily accessible for the surface radiator according to the invention.
- the lateral dimensions of the surface radiator according to the invention in the radiation plane, which in this illustration runs parallel to the leaf plane, can be seen from the plan view according to FIG. 3 .
- the heatable area is 45 mm x 45 mm.
- Such a surface radiator is designed for a consumption of 500 W of electrical power, which corresponds to a power density of approximately 250 kW / m 2 , taking into account the external dimensions mentioned.
- short-wave infrared emitters can be used. These are parallel to each other arranged, fused together in the area of the web 13 and then in the area the melted film is angled by 90 °.
