Because of the colliding flow, the heat transfer efficiency in this region is high. When the blower handles high-temperature fluid, the amount of heat that enters from the blower side to the motor side by heat conduction is large, and unless this is blocked, the temperature of the bearing or the motor rises.

In the above example, the double-barrel structure is used, but any other method may be used as long as an appropriate amount of air can be introduced from each flow hole. Further, although cooling air is used as the cooling fluid, it goes without saying that the cooling fluid may be, for example, various cooling gases other than air.

体機械。3. A motor-integrated fluid machine in which a fluid machine and its drive motor are integrated, and a cooling fluid is introduced into at least both sides of the stator in the casing of the drive motor casing. A plurality of cooling fluid introduction holes are provided, a slit through which cooling fluid flows is provided at the center of the stator of the drive motor, and a cooling fluid discharge passage communicating with the slits is passed through the casing. The cooling fluid introduced through the plurality of cooling fluid introduction holes flows into the gap between the stator and the rotor from both ends and cools the motor discharged through the slit and the cooling fluid discharge passage. A cooling fluid passage is formed, a gap is provided between the casing of the fluid machine and the driving motor, and a cooling fluid introduction hole for introducing a cooling fluid into the gap is provided in the casing or drive of the fluid machine. Motor And a cooling fluid discharge passage communicating with the cooling fluid in the gap, penetrating the casing of the fluid machine or the casing of the drive motor, and flowing into the gap from the cooling fluid introduction hole. A fluid integrated with a motor, characterized in that a cooling fluid passage is formed to radiate heat transmitted from the fluid machine side to the motor side, the cooling fluid flowing through the gap and being discharged through the cooling fluid discharge passage. machine.
