Tank for liq. cooled transformers - has each cooling element in side walls closed against tank inner space by strips over entire height, to form channels

摘要

The side walls of the tank are folded from sheet metal and contain a series of cooling elements. Each such element is closed almost over its entire height by a strip (3) against the tank inner space (1). Simultaneously it forms an orthogonal channel, connected on top and bottom by horizontal channels to the tank inside. The horizontal channels have a greater inside width than the orthogonal channel due to embossed notches (5) transversely to the edges of the folded sheet metal. Preferably the inside width of the horizontal channels is twice that of the orthogonal one. Additional strips may divide the cooling elements into several orthogonal channels for parallel partial flows.
