PURPOSE:To mitigate the ununiformity of a radiating efficiency due to different circumferential conditions by a method wherein outside and inside panel groups are attached to an upper header and a lower header with different pitches respectively so as to give different radiating efficiencies respectively, in the radiator for an oil transformer or the like. CONSTITUTION:The panel group 13, having the width W' of panel and the pitch N1, and the panel group 14, having the width W' and the pitch N2, are connected so as to pinch a pair of upper and lower headers 12a, 12b, equipped with a coupling 11 for connection at one end in the lengthwise direction thereof, and the pitch N2 is determined so as to be larger than the pitch N1. In case they are attached to the oil transformer or the like, the panel group 14, having the larger pitch, is attached to the side, in which the radiating efficiency is worsened by the circumferential condition, or the inner side of the transformer when it is seen from the transformer tank 15. Thus, the ununiformity of the radiating efficiency due to the circumferential conditions is mitigated to improve the radiating efficiency as a whole. As a result, the necessary width as well as the number of sheets of the panel may be minimized and the external size thereof may be made smaller. |
