Title: ELECTRICALLY DRIVEN PUMP
Abstract:
Provided is an electrically driven pump (1) for sucking in a refrigerant and discharging the refrigerant. The electrically driven pump (1) is provided with: a pump region (P) in which a pump chamber (100a) is disposed, the pump chamber (100a) having a suction opening (101) which sucks in the refrigerant and a discharge opening which discharges the sucked-in refrigerant; a motor region (M) in which a motor (300) is disposed, the motor (300) rotating an impeller (200) disposed within the pump chamber (100a); and a motor drive circuit region (D) in which a circuit board (420) is disposed, the circuit board (420) having mounted thereon a plurality of circuit components (410) for driving the motor (300). The motor drive circuit region (D) is disposed adjacent to the pump chamber (100a) through which the refrigerant sucked in from the suction opening (101) flows.
