摘要： The present invention is provided with: a compressor which is mounted on a bottom plate (50) having protrusions and recesses on the surface thereof and which compresses a refrigerant; and a noise insulation cover (51) which covers the entire perimeter of the side portion of the compressor, has a base shaped to match the protrusions and recesses of the bottom plate (50), and is mounted while the entire perimeter of the noise insulation cover is in contact with the bottom plate (50). The present invention is further provided with a noise insulation cap (52) for covering the upper part of the compressor. The noise insulation cap (52) is mounted and fitted to the entire perimeter of the upper end of the noise insulation cover (51). As a result of this configuration, the gap between the base of the noise insulation cover (51) and the bottom plate (51) having the protrusions and recesses can be reduced, and noise is prevented from leaking from the base of the noise insulation cover (51).

摘要： The present invention prevents an electrical component from being adversely affected by dew water and also prevents a coolant from absorbing heat other than heat from a cooling target when a heat-generating electrical component is cooled using the cooling heat of a coolant flowing through a coolant circuit. An electrical component cooling device (11A) comprises: coolant piping (28) that constitutes a coolant system of an outdoor unit; a heat sink (25) through the inside of which the coolant piping (28) extends and to a surface of which cooling heat of a coolant flowing through the coolant piping (28) is transmitted; electrical component fixing parts (25a, 25b) that are provided on the surface of the heat sink (25) and that fix in place electrical components (21, 22) having heat generating properties; and a heat insulation member (35a) that is provided so as to cover the surface of the heat sink (25) other than the areas where the electrical component fixing parts (25a, 25b) are located
