Abstract
A fluid machine includes a housing including a suction port through which fluid is drawn, an electric motor accommodated in the housing, and a drive device configured to drive the electric motor. The drive device includes a circuit board, a heat-generating component, and a metal member. The circuit board includes a pattern wire. The circuit board is opposed to an outer surface of the housing. The heat-generating component is located between the circuit board and the outer surface of the housing and spaced apart from the circuit board. The heat-generating component generates electromagnetic noise. The metal member is at least partially located between the circuit board and the heat-generating component. The metal member is configured to transmit heat from the heat-generating component to the housing and absorb or block the electromagnetic noise.
