Abstract

PURPOSE:To obtain a tank having high heat radiating effect and small size and light weight by bending in wavy shape a sheet-shaped thin steel plate to form a finlike extension when a tank for an oil-immersed electric device such as a transformer is constructed and composing the tank at the long side of two groups of perpendicularly crossing extensions. CONSTITUTION:Sheet-shaped thin steel plates 11 are bent in wavy shape to form finlike extensions 11a disposed at the prescribed interval, and reinforcing pieces 16 are welded to the ends of the extensions. Finlike extensions 11b are again formed at the flat part 14 of planar plate shape, are secured at the ends with reinforcing member 16, and wavy heat radiating plates 10A having finlike extensions is similarly formed via the flat part therebetween. The heat radiating plate 10A thus formed is disposed along the long side of a tank, and a wavy heat radiating plate 10B provided continuously with a number of finlike extensions 11a is provided ordinarily at the short side. Thus, a tank having low cost, high heat radiating effect and high mechanical strength can be obtained in this manner.
