<p>PURPOSE: A transformer case of a module type radiation fin structure is provided to increase heat radiation effect by the simple structure of insulation oil circulation. CONSTITUTION: A case main body (31) comprises an upper main body (31a) in which a cover plate (36) is combined in the upper side and a lower main body (31b) which is separated from the upper main body. A heat radiation fin module (32) is combined with each side of the case main body. The heat radiation fin module comprises a joining plate (34) and a heat radiation fin (35) protruding on the joining plate. A plurality of inlets and outlets connected to the main chamber are formed in the joining plate. A junction wall combined with the joining plate (40) is formed in the heat radiation fin.</p> |
