Claims (1)

[Scope of utility model registration request] An overhanging oil chamber extends outward from the tank side wall surface using a wavy heat dissipating plate formed by bending a thin steel plate into a wave shape and forming a large number of heat dissipating fins, and the overhang oil chamber is arranged so as to be substantially parallel to the tank side wall. In an oil-immersed equipment equipped with a tank formed with a plurality of overhanging heat radiating parts having the heat radiating fins protruding from the sides, the height dimensions of the plurality of overhanging heat radiating parts are sequentially made different. The lower or upper part is not shaped like a step,
An oil-immersed device characterized in that the stepped portion is provided with an air blower that blows air through an air duct in a direction parallel to the heat radiation fins.
