Abstract (en)
[origin: WO2021022507A1] A cooling device (10) for a transformer (100) includes a row of three coil devices (2,4,6). The cooling device (10) comprises a first air fan (16) and a first ventilation unit (18). The first air fan (16) is arranged at a first side of a first coil device (4) of the three coil devices (2,4,6). The first ventilation unit (18) includes a first wing branch (13) coupling to the first air fan (16) and adapted to communicate air from the first air fan (16). The first wing branch (13) is adapted to extend into the bottom or the top of a first gap between the first coil device (4) and a second coil device (2), and comprises a first set of openings (15,17) adapted to communicate the air in the vertical direction. By utilizing embodiments of the disclosure, a better cooling effect can be achieved in a dry-type transformer (100).
