Claims

[Scope of utility model registration request]

(1) Provide a heat exchange chamber with cooling pipes in the stator frame,
In a fully enclosed pipe-cooled rotating electrical machine, in which internal air that has cooled the rotating electrical machine body is circulated around the cooling pipe, and outside air is circulated through the cooling pipe for heat exchange, the cooling pipe is screwed onto the end with a nut. A completely enclosed pipe-cooled rotating electrical machine characterized by a fully enclosed pipe-cooled rotating electric machine that is fastened to the end plate of a heat exchange chamber.

(2) The fully enclosed pipe-cooled rotating electric machine according to claim 1, wherein the end of the cooling pipe on the outside air inlet side is shaped like a trumpet and is engaged with the end plate of the heat exchange chamber.

(3) Utility model registration claim 1, characterized in that the cooling pipe has spacers each having a depth of a predetermined gap with respect to the end plate of the heat exchanger at both ends, and nuts are screwed thereto. The fully enclosed pipe-cooled rotating electric machine described.
