型化するため騒音が増加するという問題があった。The installation foundation of the rotary electric machine is desired to have a flat and simple floor shape, and it is desired to have low noise for maintenance. However, in the conventional air-cooled heat exchanger type rotary electric machine, the mounting height of the external fan fan from the floor surface becomes large, so it is necessary to dig down the floor of the external fan fan mounting portion from the foundation of the rotary electric machine. Further, there is a problem that noise increases as the size of the external fan increases.

要はない。1 is a block diagram of an air-cooled heat exchanger type rotary electric machine according to an embodiment of the present invention. 1, the same parts as those in FIG. 2 are designated by the same reference numerals. The rotating shaft 1, the rotor 2, the inner fan fan 4, and the stator 5 are the same as those in FIG. In the present invention, the outer fan fan 3 is a double blade and is attached to one end of the rotary shaft 1. The wind sucked from both sides of the external fan fan 3 passes through the external fan fan cover 8 and passes through the pipe of the air-cooling heat exchanger 6.
The hot air circulated from the inside of the rotating electric machine to the air-cooling heat exchanger 6 via the inner fan fan 4 is heat-exchanged with the cool air of the outer fan fan 3 in the air-cooling heat exchanger 6. Twin wings fan fan 3
Since the air is sucked in from both sides, the air volume is divided into two, and the diameter can be made shorter than that of the conventional single-wing outer fan fan. As a result, the mounting dimension of the external fan fan 3 is within the center height of the rotary electric machine, and the bottom of the external fan fan cover 8 is on the foundation of the rotary electric machine, so it is not necessary to make a groove in the installation base of the rotary electric machine. .
