PROBLEM TO BE SOLVED: To provide an outdoor unit of an air conditioning device capable of suppressing degradation of each of electric components of a control circuit and shortening of its lifetime, without increasing a size of a control box even when the control circuit including a boost converter is used.SOLUTION: A heat sink 61 to cool an inverter 6 for driving a compressor, a heat sink 71 to cool an inverter 7 for driving an outdoor unit fan, and a reactor 2 as one component of a boost converter are disposed on an outer surface of a back plate 11 of a control box 10 in a state of being exposed on an air channel. The reactor 2 is accommodated in a case 21 of rectangular parallelepiped shape, and disposed on a left obliquely-downward part of the heat sink 61, so that cooling air in the air channel flows to the heat sink 61 side. |
