EXPANSION RADIATOR FOR A HERMETICALLY CLOSED ELECTRICAL TRANSFORMER

摘要

The invention relates to an expansion radiator for a hermetically closed electrical transformer or a throttle to which a heat exchange fluid is delivered via an inflow means (2), is passed through an expansion shaft cavity (7) formed by an expansion shaft (9) and an associated cover part (6), and then is drained off via outflow means (12), characterised in that a flow guiding part (5) which steers the flow direction of the heat exchange fluid is arranged in a mouth region (4) between the inflow means (2) and the expansion shaft cavity (7).
