ABSTRACT:
A transformer assembly comprises a tank body enclosing a transformer and a cooling liquid. A cooling collar is fixedly attached to the outer surface of the tank body. The cooling collar is formed separately from the tank body in a corrugated shape so as to be elastically expandably mounted onto the tank body. The collar is attached to the tank body by a thermally conductive epoxy. The corrugations of the collar define cooling fins for dissipating heat from the tank body. The cooling collar can be of one-piece or multi-piece construction, the latter comprising a plurality of collar segments hooked together in end-to-end fashion.
