Abstract
This invention is about a method and a device for equalizing warming processes in dielectric loads using electric/electromagnetic fields at frequencies below 900 MHz. Characteristic for the invention is that the load is surrounded by a field equalizing material and that the load and the electric/electromagnetic field is moved relative to each other.
Claims11
An appliance for reducing overheating of areas in a dielectric load placed in an electric/electromagnetic field at one or several frequencies below 900 MHz characterized by that the dielectric load is surrounded completely or partly by one or several dielectric material and that the a equalization of heat in the load is obtained by moving the load or a part/parts of the load and the electric/electromagnetic field relative to each other.
A device for reducing overheating of areas in a dielectric load placed in an electric/electromagnetic field at one or several frequencies below 900 MHz, the dielectric load consists of one or several dielectric materials and is surrounded completely or partly by one or several dielectric materials, the load and the surrounding matters is placed in a cavity equipped with an antenna/applicator alternatively between a pair of capacitors placed in a shielding cage characterized by that the dielectric material surrounding the dielectric load is deformed one or several times during a warming process.
