1. A package fluid machine having a main intake port that takes in the fluid, comprising:
a plurality of compressor units disposed in a plurality of stages in a longitudinal direction of the package fluid machine,
each of the plurality of compressor units including a compression portion that compresses a fluid, a motor that drives the compression portion, and a cooling fan that is driven by the motor;
wherein the compressor unit, the compression portion and the motor are arranged in the same stage,
a machine chamber in which the plurality of compressor units are disposed;
an inverter chamber which is adjacent to the machine chamber and in which multiple inverters are disposed in the longitudinal direction corresponding to the each of compressor units;
a partition wall that partitions off the machine chamber from the inverter chamber and has multiple openings corresponding to each of the compressor units; and
a plurality of inverter intake ports that are disposed in the inverter chamber to take in a cooling gas to each of the multiple inverters,
wherein for each of the plurality of the compressor units, the cooling fan is disposed on a side of the machine chamber, a respective opening of the multiple openings being located on the side, and
the cooling fan is driven to cause the cooling gas to flow from a respective one of the inverter intake ports to the opening to cool the inverter.
