Claims

[Scope of utility model registration request]

The central flat plate part of the corrugated heat sink is bent so that its base surfaces face each other, and the upper and lower edges of the fin-like overhanging parts are pressure welded. A first radiator that is welded and uses the fin-like overhang as a cooling path, and the flat plate portions at both ends of a plurality of first radiators are joined together and welded to a frame to form a side surface of an oil-filled electrical appliance tank. In the method, a flat plate is welded to the base surface of the corrugated heat sink, and an inlet and an outlet for the fin-like overhang are formed at both upper and lower edges of the flat plate,
The inflow port and the outflow port are connected to holes drilled in the side surfaces of two headers arranged with an interval in the vertical direction to form a second corrugated radiator, and this second corrugated radiator is connected to the An oil-filled electrical appliance characterized in that the second wave-shaped radiator is installed outside the first radiator so as to communicate with each hole in the upper frame plate and the lower frame plate of the electricity-injector tank.
