An induction electric heater comprises a magnetic core with windings located at legs thereof and a tube heat exchanger which encircles the legs with windings. A heat exchanger is made as at least a single-turn spiral, whose each turn comprises in series connected direct and return waves having the equal number of half-waves, opposite-directed, which change one another at the end core leg, points of wave crossing both turn and spiral are connected to one another. |
