<p>The present invention relates to a heat-radiating device for a transformer. According to the present invention, heat generated from a transformer body (11) is transferred to insulation oil and is discharged to the outside at radiators (15). First cooling fans (20) and second cooling fans (30) are used for heat radiation at the radiators (15). Multiple first cooling fans (20) are arranged at different heights starting from the upper portion of the radiators (15) to the lower portion thereof. The second cooling fans (30) are arranged on the lower portion of the radiators (15) to form a cooling air flow from the lower portion of the radiators (15) to the upper portion thereof. The second cooing fans (30) are arranged on the lower portion of a radiator (15) lying opposite the radiator (15) on which the first cooling fans (20) are arranged. According to the present invention, the first cooling fans (20) and the second cooling fans (30) have different wind amounts. The wind amount of the first cooling fans (20) increases towards the upper portion of the radiators (15) and increases towards an outer chest (13) of the radiator body (11). The wind amount of the second cooling fans (30) increases in proportion to the distance from the radiator (15) on which the first cooling fans (20) are installed, and increases in proportion to the proximity to the outer chest (13). The present invention, as described above, is advantageous in that design of the radiators (15) of the heat-radiating device is optimized, and the heat-radiating capability improves comparatively.</p> |
