Abstract:
The present invention comprises an inverter and a case that houses the inverter. The case has a bottom section that extends along a horizontal plane, and a side wall section that protrudes upward from an outer edge of the bottom section. The bottom section is provided with a main recessed section that opens upward, a first recessed section and a second recessed section that are recessed downward from a bottom surface of the main recessed section, a first flow passage that extends along the horizontal plane, through the interior of the bottom section, and opens to the first recessed section and an outside surface of the case, and a second flow passage that extends along the horizontal plane, through the interior of the bottom section, and connects the second recessed section and the outside surface of the case. The opening of the main recessed section is covered by a section of the inverter. Pipes through which a refrigerant flows are respectively connected to the openings to the outside surface of the case of the first flow passage and the second flow passage. A section of the second flow passage overlaps with the main recessed section when viewed from a vertical direction.
