Abstract

An electric compressor, including: a housing; a compression unit provided in the housing; a motor unit provided in the housing to drive the compression unit; and an inverter unit coupled to one side of the housing and controlling the motor unit, and the inverter unit includes: a support body disposed on one side of the housing; and an inverter cover coupled to one side of the support body; and the support body includes: a center part allowing a circuit board to be seated thereon; and a first receiving part extending from the center part toward a radially outer side of the center part, and having a noise reduction element disposed therein.

First claim

What is claimed is:

1 . An electric compressor, comprising:
a housing; a compression unit provided in the housing; a motor unit provided in the housing to drive the compression unit; and an inverter unit coupled to one side of the housing and controlling the motor unit, wherein the inverter unit further comprises:
a support body coupled to the one side of the housing; and
an inverter cover coupled to one side of the support body; and
wherein the support body further comprises:
a center part allowing a circuit board to be seated thereon;
a first receiving part extending from a radially outer side of the center part, and having a noise reduction element disposed therein; and
a second receiving part disposed in a line on a radially outer side of the first receiving part and has a high voltage connector disposed therein, wherein the high voltage connector is connected to the noise reduction element through a first bus bar, and the noise reduction element is connected to the circuit board through a second bus bar, and wherein the high voltage connector, the noise reduction element and the circuit board are integrated into the support body;
wherein an intelligent power module (IPM) connected to the circuit board is in contact with the housing.

2 . The electric compressor of claim 1 , wherein the support body further comprises a third receiving part extending from the radially outer side of the center part and having a low voltage connector disposed therein.

3 . The electric compressor of claim 2 , wherein the first receiving part and the third receiving part extend in parallel in a same direction from the center part.

4 . The electric compressor of claim 1 , wherein the inverter cover covers the center part and the first receiving part.

5 . The electric compressor of claim 1 , further comprising a metal electromagnetic wave shielding member surrounding the support body.

6 . The electric compressor of claim 1 , wherein a first sealing member is disposed between the inverter cover and the support body, and a second sealing member is disposed between the support body and the housing.

7 . The electric compressor of claim 1 , wherein a fastening member is installed to the housing by penetrating the inverter cover and the support body.

8 . The electric compressor of claim 1 , wherein a protrusion protruding toward the support body is provided on the one side of the housing so as to be contactable with the intelligent power module (IPM).

9 . The electric compressor of claim 1 , wherein the noise reduction element is welded to the first bus bar and the second bus bar.

10 . The electric compressor of claim 1 , wherein the noise reduction element is a common mode (CM) choke.

11 . An electric compressor, comprising:
a housing; a compression unit provided in the housing; a motor unit provided in the housing to drive the compression unit; and an inverter unit coupled to one side of the housing and controlling the motor unit, wherein the inverter unit further comprises:
a support body coupled to the one side of the housing; and
an inverter cover coupled to one side of the support body; and
wherein the support body further comprises:
a center part allowing a circuit board to be seated thereon; and
a first receiving part extending from a radially outer side of the center part, and having a noise reduction element disposed therein, wherein a speed rivet is installed to penetrate the circuit board and the support body, and a bolt is installed to the housing by penetrating the speed rivet.
