The present invention relates to a radiator for transformer. The radiator of the present invention exchanges heat with the outside by passing insulating oil containing heat generated in the main body of a transformer. Multiple radiating plates (10) included in the radiator respectively form an internal flow path (13) inside by mutually combining a first panel (11) with a second panel (12). Distribution protrusions (20) and swirl prevention protrusions (30) are formed to protrude from the first panel (11) and the second panel (12) to the internal flow path (13). The distribution protrusions (20) have a hemisphere shape with a cut upper end, are arranged in line in a direction which is perpendicular to the flow direction of the insulating oil, and are formed to be dislocated from a line with adjacent distribution protrusions (20). The swirl prevention protrusions (30) are installed between the distribution protrusions (20) in the line of the distribution protrusions (20). The swirl prevention protrusions (30) prevent a swirl from being generated in the rear end of the distribution protrusions (20) by preventing the cross section of the flow of the insulating oil from being dramatically changed since the flow width of the insulating oil gradually becomes wider from the upper stream of the flow direction to the lower stream of the flow direction. According to the present invention like the forementioned, the size of the radiating plates (10) are relatively reduced by increasing the heat exchange efficiency of the radiating plates (10). |
