1-19. (canceled)
An electric compressor comprising:
- a housing;
- a motor provided inside the housing;
- a compression mechanism receiving power from the motor and compressing a refrigerant;
- and
- an inverter controlling the motor, wherein the inverter comprises a circuit board on which a plurality of elements is mounted and a frame coupled to the circuit board, and wherein the frame comprises a support plate, a side plate protruding from the support plate toward the circuit board, an array plate on which a switching element connected to the circuit board is arranged, and a connection bar connecting the support plate and the array plate.
An inverter manufacturing equipment comprising:
- a first dummy plate fixed to a frame of an inverter having a circuit board on which a plurality of elements of an electric compressor are mounted and the frame on which a switching element is disposed;
- and
- a second dummy plate coupled to the first dummy plate to contact the switching element and to fix and radiate the switching element and the plurality of elements.
An inverter manufacturing method comprising:
- a first preparation step of inserting a guide pin of an inverter manufacturing equipment into a fastening hole of a frame of an inverter and seating the inverter on a first dummy plate, wherein the inverter manufacturing equipment comprises the first dummy plate fixed to the inverter of an electric compressor and a second dummy plate coupled to the first dummy plate to contact the inverter, fix elements of the inverter, and radiate heat from the elements of the inverter;
- a second preparation step of coupling the second dummy plate to the first dummy plate, fixing the elements of the inverter, and connecting the elements to the heat proof plate of the second dummy plate;
- a soldering step of soldering the elements;
- and
- a withdrawing step of withdrawing the inverter from the inverter manufacturing equipment.
