Embodiment Construction

[0019] An inverter device according to one aspect of the present disclosure includes: a circuit board provided with an inverter circuit on the front surface and a heat dissipation part on the back surface; a first case part provided with an opening for exposing the heat dissipation part; The periphery of the support heat dissipation part; and the second case part is provided with a rib structure that is pressed against the surface of the circuit board and presses the circuit board toward the side of the first case part, and the first case part is mounted on the second case part. The circuit board is held between the first case portion and the second case portion.

[0020] In this inverter device, the heat dissipation part included in the back surface of the circuit board on which the inverter circuit is provided is exposed from the opening of the first case part. Therefore, it is possible to efficiently dissipate the heat generated on the circuit board from the heat sink to th...

Abstract

An inverter unit (30) of the present invention comprises: a circuit board (31) provided with a power device (37) and a capacitor (38) forming an inverter circuit on a front surface (36a), and an exposure region (SA) provided on a rear surface (36b); a lower case (33) that is provided with an exposure opening (59) for exposing the exposure region (SA), and supports the periphery of the exposure region (SA); and an upper case (32) provided with a rib structure (46) that is pressed against the front surface (36a) of the circuit board (31) to compress the circuit board (31) toward the lower case (33), the lower case (33) being attached to the upper case (32). The circuit board (31) is sandwiched between the lower case (33) and the upper case (32).

Description

technical field [0001] The present disclosure relates to inverter devices and electric compressors. Background technique [0002] Patent Document 1 and Patent Document 2 disclose an inverter type electric compressor. The electric compressor of Patent Document 1 includes a casing in which an electric motor and a compression mechanism are built, and an inverter housing portion is provided on the outer periphery of the casing. An inverter device is arranged in the inverter housing. The inverter unit converts DC current supplied from a high-voltage power source into three-phase AC current. Furthermore, the inverter device supplies three-phase alternating current to the electric motor. The electric compressor of Patent Document 2 includes a compression mechanism, an electric motor that drives the compression mechanism, and an inverter control device that controls the electric motor. Integrate these devices. The inverter control device includes a control board and a power boa...
