A suspend annular anode saturated reactor including fireproof enclosures, Two suspension arms, core radiator, Front composite connection bus bar, first and second hose couplings, Side Connecting Bus Bar, helical radiator, solenoid and core, The shape of the fire-proof enclosure is circular, solenoid, Iron core, spiral radiator, the core radiators are located in a fire-resistant enclosure, the twosuspension arms are respectively protruded from both radial ends of the fire-proof shell, the first hose joint is connected with the liquid inlet and is connected with the inlet end of the helical heat sink through the hose, The outlet end of the spiral heat sink is connected with the electromagnetic coil through a hose, a second hose joint and a coil water connection port, the other end of the electromagnetic coil is connected with a coil water outlet, the coil water connection port is arranged perpendicularly to the coil water outlet port, and the iron core heat sink surrounds the electromagnetic coil and the iron core. As that cool liquid is adopted for heat dissipation, the volume is small, the heat dissipation effect is good, and the installation design is reasonable.
