DEVICE FOR HIGH-FREQUENCY ELECTROMAGNETIC ENERGY HIGH-DUTY DISTRIBUTION

摘要

The device for the planar high-power distribution of high-frequency electromagnetic energy falls into the area of utilization of new technological applications of dielectric heating. The purpose of the device for planar distribution is the sufficient homogenisation of the applied electromagnetic field in the working space of the drier body without the necessity of applying homogenisation in the mechanical way. The mentioned purpose is attained by the fact that the electromagnetic energy of the magnetron generator (1) is delivered proportionally into the working space of the drier body (2) by the n-branch piece (3) so that the electromagnetic energy is delivered into the working space through the funnel mouth (4) of the individual branches of the branch piece (3). To prevent undesired recoils of the electromagnetic energy back to the generator (1), the wedge-shaped elements (6) are placed on the planes perpendicular to the mouth of the parts of waveguides (5) and oriented by their thin part against the direction of the electromagnetic energy effect of the generator (1).<IMAGE>
