[0026] It should be noted that in order to further improve the heat dissipation performance at both ends of the coil, in the present embodiment, rectangular notches 23 are evenly spaced on the above-mentioned connecting ring plate 22, so that the connecting ring plate 22 forms a tooth shape, which not only improves the heat dissipation, but also makes the sheet between two adjacent rectangular notches 23 have a certain degree of mobility, thereby facilitating the installation and disassembly of the magnetic column 16.
