Abstract:
A cathode ray tube (1) comprising means (6) for generating at least one electron beam, a display screen (2), a deflection unit (11) having coils (21, 22) for deflecting the electron beam(s) across the display screen (2), and a yoke ring (23) which surrounds at least one of the coils (21, 22), said yoke ring (23) being provided with at least one cooling fin (25) for dissipating heat generated by the coils (21, 22), said cooling fin (25) thermally contacting the yoke ring by means of a plurality of lugs (27) which contact a surface of the yoke ring (23),characterized in that at least one of the lugs (27) of the cooling fin (25) is arranged so as to face the display screen (2) with a thermally contacting surface free end, and at least another of the lugs (27) is arranged so as to face away from the display screen (2) with a thermally contacting surface free end.
