FIELD: smoking accessories.
SUBSTANCE: invention relates to an arrangement for induction heating containing an annular channel. Present invention also relates to an aerosol generating device comprising an induction heating assembly. To increase the efficiency of the induction heater, assembly (10) for induction heating comprises first induction coil (12) configured to generate a first variable magnetic field when the variable electric current flows through first induction coil (12). Assembly (10) for induction heating also comprises second induction coil (14) configured to generate a second variable magnetic field when the variable electric current flows through second induction coil (14). Arrangement (10) for induction heating also comprises flux concentrator (20) located around first induction coil (12) for distortion of first variable magnetic field generated by first induction coil (12). Flow concentrator (20) has a tubular shape and contains main part (24) located around first induction coil (12). Main part (24) has an inner diameter, a first end and a second end. Flow concentrator (20) also comprises first end part (26) at first end of main part (24). First end part (26) has an inner diameter, wherein inner diameter of first end part (26) is less than inner diameter of main part (24). Flow concentrator (20) also comprises second end part (28) at second end of main part (24). Second end part (28) has inner diameter, wherein inner diameter of second end part (28) is less than inner diameter of main part (24). Inner surface (30) of flow concentrator (20) forms annular channel (32) between first end part (26) and second end part (28). First induction coil (12) is located inside annular channel (32) between first end part (26) and second end part (28).
EFFECT: higher efficiency of induction heater.
