Beschreibung
Zusammenfassung:	An air heating device for a hairdryer comprises an inner tubular body (2) extending along a central axis (A) and provided with an outer surface (2b) from which a plurality of mutually angularly spaced, radial baffles (4) extend so as to define a plurality of angular sectors (S), a corrugated resistive coil (6) extending circumferentially around the inner tubular body (2), a safety device (9) placed in electrical connection with said corrugated resistive coil (6), a thermostat (10) placed in electrical connection with the corrugated resistive coil (6), and an outer tubular body (16) made of insulating material and arranged coaxially with the inner tubular body (2) around the corrugated resistive coil (6). The safety device (9) and the thermostat (10) are respectively housed in a first (S1)and a second angular sector (S2), which are adjacent to each other and separated by a shared radial baffle (11), and the corrugated resistive coil (6) comprises a plurality of first turns (7a) provided with two rectilinear po
