PROBLEM TO BE SOLVED: To provide a power control unit and electric device that are capable of appropriately cooling a first power controller and second power controller.SOLUTION: A power control unit 34 includes: a DC-DC converter 42 and inverter 44 arranged so as to be opposite to each other in the right and left direction; and a cooling passage 39 that is formed between the DC-DC converter 42 and inverter 44 and extends in the front and rear direction. The cooling passage 39 includes a coolant inlet 71a arranged on the DC-DC converter 42 side in the opposite direction and on the rear side in the front and rear direction. The inverter 44 is arranged so that the rear part of the inverter is shorter than that of the DC-DC converter 42; a slope 60b, as a guide part for guiding a coolant from the coolant inlet 71a to an opposite part of the DC-DC converter 42 and inverter 44, is provided on the rear side of the inverter 44. A separator 25 curving from part on a virtual line P, which extends to the rear side through the opposite part, toward the coolant inlet 71a is provided in the cooling passage 39.SELECTED DRAWING: Figure 7 |
