<p>In a cabinet (1), an inverter housing (2) is mounted on an inverter housing mounting surface (5). Heat-exchanger-side pipe connection ports (3) are disposed so as to extend through the inverter housing mounting surface toward a heat exchanger for use as an air-cooling device. Further, controller-mounting-side pipe connection ports (6) are disposed so as to extend on a controller mounting side (7). A refrigerant supply line (8) is a refrigerant passage through which a refrigerant is cyclically fed from the refrigerant cooling device. One end of the refrigerant supply line is connected to the heat-exchanger-side pipe connection ports or the controller-mounting-side pipe connection ports, while the other end is connected to the refrigerant cooling device that penetrates an appropriate part of a wall of the cabinet and is situated in a proper position outside the cabinet.</p> |
