Abstract

The invention provides an electric control unit and an electrical device, wherein a first electric control device and a second electric control device can be properly cooled. In the electric control unit (34), a DC-DC converter (42) and an inverter (44) are oppositely arranged on the left and right direction. Between the DC-DC converter (42) and the inverter (44), a cooling passage (39) is formed to extend along the front-back direction. The refrigerant inlet (71a) of the cooling passage (39) is arranged on the side of the DC-DC converter (42) in the opposite direction, and is arranged on the rear side thereof along the front-rear direction. In addition, the rear side of the inverter is shorter than the DC-DC converter, and is provided with an inclined part (60b) as a guiding part and configured to guide the refrigerant from the opposite part of the DC-DC converter and the inverter towards the refrigerant inlet (71a). In the cooling passage (39), a curved divider panel (25) is arranged towards the refrigerant inlet (71a) through passing through an imaginary line (P).

Description

technical field [0001] The present invention relates to a power control unit and an electrical device, in particular to a power control unit and an electrical device equipped with a first power control device and a second power control device. Background technique [0002] A high-voltage battery is mounted on a hybrid vehicle or an electric vehicle as a drive source of an electric motor. In recent years, it has been studied to place a high-voltage battery and a power control unit connected to the high-voltage battery in a vehicle interior. For example, Patent Document 1 proposes a mounting mechanism in which a high-voltage battery and a battery of a power control unit are arranged between a pair of seats arranged in the left-right direction of a vehicle (for example, refer to Patent Document 1). [0003] In Patent Document 1, a DC-DC converter and an inverter constituting a power control unit are housed in a casing in a stacked state, and are arranged on a central tunnel. ...
