Claims

[Claims for Utility Model Registration] (1) Hollow heat dissipation by corrugating a metal plate so that peaks and valleys are arranged alternately in the longitudinal direction and sealing both ends of each peak by welding. In a corrugated transformer tank having a heat dissipation fin structure having a fin portion formed therein, an outer reinforcing material is provided to surround the heat dissipation fin portion from the outside at a central portion in the width direction of the heat dissipation fin structure,
The outer reinforcing material is welded to the top of each heat dissipating fin, and an inner reinforcing material is provided at the widthwise central portion of the heat dissipating fin structure to contact the inside of the valley between the heat dissipating fin parts, and the inner reinforcing material is welded to the top of each heat dissipating fin. A transformer tank characterized by being welded to the valley between the heat dissipation fins. (2) Claim characterized in that the heat dissipation fin portion is locally recessed and provided with an inner protrusion that protrudes inside the heat dissipation fin portion, and the inner protrusion is not welded to the opposing metal plate portion. 1. The transformer tank according to 1. (3) The transformer tank according to claim 1 or 2, wherein a connecting member is attached between the heat radiation fin portion and the outer reinforcing member.
