Magnetic energy induction heating coil that high energy efficiency was protected against radiation

An object of the utility model is to provide a magnetic energy induction heating coil that high energy efficiency was protected against radiation, concrete method is: the coil is evenly around on quartz glass tube, and a plurality of magnetic stripes are fixed in the coil outside through the silica gel circle, the magnetic stripe both ends are equipped with the turning, and the magnetic stripe turning is inboard fixed towards the coil, and back leading line circle center is concentrated at coil outside formation magnetic conduction passageway with outside divergent magnetic field to these magnetic stripes. Magnetic field concentrates that the hub of a spool can reduce the external radiation, improve induction heating efficiency, the interference that reduces control circuit makes the complete machine more stable in high -power long -time running, its simple structure, low cost, simple to operate on. 本实用新型的目的在于提供种高能效防辐射的磁能感应加热线圈，具体方法是：线圈均匀绕于石英玻璃管上，多个磁条通过硅胶圈固定于线圈外侧；磁条两端设有拐角，磁条拐角朝向线圈内侧固定，这些磁条在线圈外侧形成导磁通道将外侧发散磁场集中
