It connects.
What the present invention passed through is designed to provide a kind of external transformer radiator, by the inner cavity of transformer
Heat-conducting plate is arranged in top；The heat conducting pipe outside transformer is arranged in heat-conducting plate connection, and if being provided on the pipe shaft of heat conducting pipe
Dry cooling fin.Heat-conducting plate, which absorbs, to be conducted rapidly after the heat of cooling oil by heat conducting pipe to outside transformer and will be hot by cooling fin
Amount is spilt into air.In this radiation processes, cooling oil avoids the wind of leakage without being recycled to outside transformer
Danger.The structure for simplifying transformer simultaneously, reduces occupied area.Heat-conducting plate thermal conductive contact face is big simultaneously, improves thermally conductive
Efficiency.Setting heat-conducting plate does not destroy the structure of inside transformer yet in the lumen, i.e., does not destroy the electromagnetic field knot of inside transformer
Structure, therefore not will cause point discharge effect, eliminate security risk.
