<p>The present invention relates to a radiator for a transformer. According to the radiator of the present invention, heat exchange with the outside is performed while an insulating oil, which contains heat generated from a transformer main body, passes therethrough. The radiator is provided with multiple heat sinks (10), and the heat sinks (10) form an internal passage (13) therein as a first panel (11) and second panel (12) are coupled to each other. Distribution protrusions (20) and vortex prevention protrusions (30) are formed so as to protrude to the internal passage (13) from the first panel (11) and the second panel (12). The distribution protrusions (20), which have a hemispherical shape with a cut upper end, are arranged in rows in the direction orthogonal to the flow direction of the insulating oil, and the distribution protrusions (20) are formed so as to be dislocated from each other and from the adjacent rows of the distribution protrusions (20). The vortex prevention protrusions (30) are provided between the distribution protrusions (20) in the rows of the distribution protrusions (20). The width of the vortex prevention protrusion (30) increases from the upstream side to the downstream side in the flow direction of the insulating oil, and thus, a sudden change in the cross-sectional flow of the insulating oil is prevented and no vortex is generated at the back end of the distribution protrusion (20). According to the present invention, heat exchange efficiency is increased in the heat sink (10), and the heat sink (10) can be relatively reduced in size.</p> |
