A short-wave infrared surface radiator, with at least one infrared radiator, is equipped with a cladding tube. The cladding tube encloses, in a vacuum-tight manner, a heating element, which has an electric connection that is guided out of the cladding tube on a connection-side end via a pinch on a face of the cladding tube. A molybdenum foil is sealed into the cladding tube. Several infrared radiators that are connected to each other are arranged in an adjacent and parallel design while forming a joint radiating plane, with the connection-side end of the cladding tubes each being angled with regard to the radiating plane. The cladding tubes are fused together in an area of their front side that is opposite an angled section.

Short-wave infrared surface radiator assembly with angled connection

An infrared radiator has a twin tube with an inner bridge that separates two housings which run along the longitudinal direction of the tube. A first heating spiral arranged in a first one of the housings is provided with an external electrical current supply and has a first end connected to a connection wire or a second heating spiral arranged in the second housing. A bore is formed in the inner bridge adjacent a second end of the first heating spiral and through which a connection body can extend from one housing into the other housing. The first heating spiral is thereby electrically connected to the connection wire or the second heating spiral. At least the first heating spiral is mounted under pull tension in the housing. Furthermore, for simplifying the mounting of the heating spiral of the infrared radiator, the bore is formed by boring through the jacket of the twin tube and the inner bridge. The connection body is then inserted into the through bore and the inner bridge, and is electrically connected to the first heating spiral and to the connection wire or to the second heating spiral. The bore is then closed off.
