An inverter module according to an embodiment of the present invention comprises: a high voltage circuit unit which generates an inverter control voltage and a motor driving voltage by using a first DC voltage; a high voltage circuit pattern which electrically connects the high voltage circuit unit; a low voltage circuit unit which communicates with an external device by using a second DC voltage having a smaller magnitude than the first DC voltage; and a low voltage circuit pattern which electrically connects the low voltage circuit unit. The high voltage circuit pattern and the low voltage circuit pattern are spaced apart from each other.

Inverter module and electric compressor comprising same

Disclosed herein is a motor-driven compressor with an inverter that is connected with an external power source via a connector part and controls a driving part which drives a compressing part to compress fluid. A printed circuit board is provided between the connector part and the driving part. Thus, noise transmitted from the driving part to the connector part is reduced, so that it is possible to minimize the transmission of the noise to an external power source.

Electric compressor

Disclosed herein is an electric compressor including: a main housing () having therein a suction chamber into which low-temperature refrigerant is drawn; an inverter housing () including an internal seating surface () formed adjacent to the suction chamber, with at least one inverter element () fixed at a surface thereof to the internal seating surface () while making contact with the internal seating surface (), the at least one inverter element () conducting heat to the main housing (); and at least one heat dissipation cover () disposed toward the main housing () while facing another surface of the inverter element () and enclosing the inverter element (), the at least one heat dissipation cover () having therein a receiving space () in which the inverter element () is received.

An apparatus for cooling an inverter of a vehicle which receives power supplied from a vehicle battery and controls the rotation speed of a motor, wherein the apparatus includes an inverter housing configured to support the inverter, and a heat dissipation unit provided at a predetermined position in the inverter housing and configured to come into contact with an outer circumferential surface of the capacitor so that heat of the capacitor is transferred to the inverter housing.

Device for radiating heat of capacitor of an inverter in an electric compressor

Disclosed herein is an apparatus for cooling an inverter of a vehicle which receives power supplied from a vehicle battery and controls the rotation speed of a motor. The apparatus includes an inverter housing configured to support the inverter, and a heat dissipation unit provided at a predetermined position in the inverter housing and configured to come into contact with an outer circumferential surface of the capacitor so that heat of the capacitor is transferred to the inverter housing.

An electric compressor includes a cover. The cover is reinforced by forming straight ribs, ring ribs, connection ribs, or hexagonal ribs having a honeycomb structure. The straight ribs, rings ribs, connection ribs, or hexagonal ribs are formed on the inner side or the outer side of a body of the cover on a side of an inverter.
