Materials:
The exchange surfaces of the coolers of the electrical
machines are mostly made ofmetals such as copper
or copper alloys for the tubes and copper for the fins.
As far as
air coolers
are concerned their surfaces can also be made of
steel tubes fitted with aluminium or steel fins, possibly
protected.
Tube sheets and boxes for the water distribution are
either made of steel or of copper alloys (brass or copper-aluminium)
according to the type of the circulating water. |
