The present invention relates to a radiator for a transformer. The radiator of the present invention comprises: an upper header pipe (10) connected to the upper portion of an enclosure of the transformer body; a plurality of radiating plates (20) connected to the upper header pipe (10) in sequence to receive an insulating oil; a lower header pipe (10') that returns the insulating oil, which has released heat to external air while flowing within the radiating plates (20), into the enclosure; and bridge pins (30) installed in air passages (22) formed between the radiating plates (20) to exchange heat with external air while making contact with the external air. The bridge pins (30) are formed of a material having a high heat transfer rate and include first and second attachment parts (31, 32) installed to make contact with the outer surfaces of the radiating plates (20) and a connecting part (33) that interconnects the first and second attachment parts (31, 32). The connecting part (33) has a through-hole (35) formed therein to allow air to pass through the through-hole. According to the present invention, it is possible to reduce a difference in temperature between the radiating plates (30), thereby enhancing the heat exchange efficiency. |
