Patent ID: 11287145

Abstract:
A fluid machine that performs efficient cooling of a control system, such as a control device. The fluid machine is provided with: a fluid machine body; a drive source; a control device; a housing in which the fluid machine body, the drive source, and the control device are housed; and a cooling fan. The housing has a plurality of intake openings for introducing cooling air into the interior thereof and one exhaust opening, and includes a partition wall which partitions the interior of the housing into a first compartment and a second compartment and which has a communication portion providing communication between the first compartment and a part of the second compartment. A first intake opening among the plurality of intake openings is disposed in a housing wall of the first compartment in which at least the control device is disposed, and a second intake opening is disposed in a housing wall of the second compartment in which at least the drive source is disposed. The exhaust opening discharges the cooling air that has flowed from the first intake opening into the second compartment via the communication portion and that has cooled one of the fluid machine body and the drive source, and the cooling air that has been taken in via the second intake opening. A part of the control device is disposed facing an area of the first compartment downstream of the first intake opening and upstream of the communication portion.
