The present invention provides a scroll type fluid machine which enables both of a fixed scroll and an orbiting scroll to be cooled by means of a cooling fan, and which enables an overall size of the machine to be compact. Cooling fans 38 A and 38 B are connected to a rotary shaft 18 between an electric motor 15 and orbiting scrolls 26 A and 26 B. Outer cases 3 A and 3 B are provided with flow inlet openings 42 A and 42 B, flow outlet openings 43 A and 43 B, scroll ducts 44 A and 44 B and cooling device ducts 46 A and 46 B. Compression portions 6 A and 6 B are operated by rotatably driving the rotary shaft 18 using the electric motor 15 . In this instance, the cooling fans 38 A and 38 B are rotated with the rotary shaft. Therefore, with a simple structure having no electric fans, the fixed scrolls 7 A and 7 B, the orbiting scrolls 26 A and 26 B and the cooling device 47 can be efficiently cooled, and a compressor having a compact size and a high cooling performance can be formed.
