<p>A heat exchanger panel suitable for cooling fluid filled electrical apparatus, such as electrical distribution and power transformers, and method of constructing same, which withstands substantially higher pressures without adding significantly to the weight of the heat exchanger. The metallic sheet which is used to construct the heat exchanger panel includes edges which define a substantially rectangular configuration, with predetermined opposite edges therof being folded to increase the edge thickness of the sheet prior to forming the fins. The fins are formed via bend lines which extend from folded edge to folded edge. This provides at least twice the material thickness where the heat exchanger panel is welded to the tank of the associated apparatus, and at least four times the material thickness where the folded fin is welded to form the fin cavity.</p> |
