High-frequency coil structure capable of simultaneous producing five silicon cores and other crystal material

Abstract

The invention discloses a high-frequency coil structure capable of simultaneously producing five silicon cores and other crystalline materials, and relates to the technical field of the high-frequency coils. The high-frequency coil structure comprises a splitter box (14) for guiding current (15), and five inner bores (8) one inner bore (8) of which is arranged at the middle part of the high-frequency coil and four inner bores (8) of which are evenly distributed around the inner bore at the middle part in a 'cross' shape; an oblique opening (13) arranged on one side of a current delivery and cooling water delivery copper pipe A(11) and a current delivery and cooling water delivery copper pipe B(12) is in through connection with the inner bore (8) at the middle part; and the splitter box (14) extends outwards to the position between every two inner bores (8) except for the oblique opening (13) from the inner bore (8) at the middle part. The high-frequency coil structure can cause the current to evenly surround the five inner bores for running under the current splitting action of the splitter box while the current is running, thus realizing the purpose that the current is evenly distributed around the five inner bores.

Description

Technical field: [0001] The invention relates to the technical field of high-frequency coils, in particular to a new type of coil that can distribute current evenly around the inner hole, heat silicon cores or other crystal materials evenly through the current, and produce five silicon cores and other crystal materials at the same time. High frequency coil structure. Background technique: [0002] At present, silicon cores are used in a huge amount in China; in the existing process of producing silicon cores, monocrystalline silicon and other material crystal zone melting methods, most of them use a monocular high-frequency coil, and its working principle is as follows: When working, pass high-frequency current to the high-frequency coil, so that the high-frequency coil generates current to inductively heat the raw material rod, and the upper end of the heated raw material rod forms a melting zone, and then inserts the crystal into the melting zone, and slowly lifts the crys...

Problems solved by technology

[0006] After two years of use, the current running around the inner hole failed to achieve the expected purpose. As shown in the above two patent application documents, when the current runs around each inner hole, the inner hole in the middle will appear There are more currents running, and the surrounding current of the other four inner holes is affected by the principle of high-frequency current operation, so that the temperature of the inner hole connected to the inclined opening is much higher than the other four inner holes, especially the one farthest from the inclined opening. The inner hole (that is, the current takes a shortcut), due to the phenomenon of the current taking a shortcut, the result is that the diameter of the raised crystals is different, resulting in an increase in the number of defective products
