Problems solved by technology

As a result, due to the given position of the nodes of the parallel circuit, it may no longer be possible to freely choose the conductor route design
Furthermore, a higher conductor routing density may result at parallel nodes, which in turn has an effect on the temperature distribution on the carrier, especially on the heating surface

Embodiment Construction

[0084] figure 1 A top view of a first embodiment of an infrared panel radiator according to the invention is shown, which is generally assigned the reference number 100 . The infrared panel radiator 100 is suitable for use in an apparatus for producing flexible printed electronics (not shown). It comprises a plate-shaped substrate (which is a carrier within the scope of the invention) 101 , a conductor track 102 applied to the substrate 101 , and two conductor tracks 103 a , 103 b for electrical contacting of the conductor track 102 .

[0085] The plate-shaped substrate 101 is made of quartz glass having a chemical purity of 99.99% and a cristobalite content of 0.25%, to which elemental silicon is added in an amount of 5% of the total mass. The elemental silicon phase is homogeneously distributed in the quartz glass in the form of non-spherical domains. The largest average size (median) of the Si phase domains is in the range of about 1 μm to 10 μm. The density of the plate...

Abstract

Known infrared surface emitters comprise a carrier with a heating surface and with a conductor track applied to a conductor track covering surface of the carrier and consisting of an electroconductiveresistive material that generates heat as a current flows through, the conductor track comprising a first conductor track section for producing a first surface output and a second conductor track section for producing a second surface output different from the first surface output. The aim of the invention is to provide an infrared surface emitter with a high level of irradiation, designed to emit radiation with an irradiation strength that is as homogeneous as possible. To this end, the carrier contains a composite material comprising an amorphous matrix component and an additional componentin the form of a semiconductor material, and the first conductor track section and the second conductor track section are connected in series and differ from each other in terms of the covering density thereof and / or the conductor cross-section thereof.

Description

technical field [0001] The invention relates to an infrared panel radiator comprising a carrier with a heating surface and a conductor track (printed conductor, conductor circuit) made of an electrically conductive resistive material which generates heat and is absorbed when current flows Applied to a conductor track laying (occupancy, occupation) surface of a carrier, wherein the conductor track comprises a first conductor track segment for generating a first power per unit area and for generating a second power per unit area different from the first power per unit area of the second conductor line section. [0002] Infrared panel radiators within the scope of the invention exhibit heating surfaces with panel-like two-dimensional or three-dimensional emission properties. Their panel-like emission properties make them easy to adapt to the geometry of the surface of the heating item to be heated, making uniform irradiation of two or surfaces of the heating item in three dimens...
