Abstract: A radiator chamber is provided in a top compartment of a package, whereas an engine is provided in a bottom compartment. Outside the package, a battery unit is attached to an external wall panel (e.g., lower panel) of the bottom compartment. The battery unit includes a dedicated unit ventilation fan and a unit ventilating section that introduces outside air into an enclosure of the battery unit. The enclosure has a lower portion thereof divided to accommodate a package ventilating section that ventilates the bottom compartment of the package. There is provided a detachable bottom compartment inspection window in the external wall panel below the battery unit.

Abstract: A package has its internal space divided into a top compartment and a bottom compartment. The bottom compartment contains the engine. The top compartment is further divided by a partition wall into a first top compartment (e.g., a radiator chamber) and a second top compartment (e.g., a device installation chamber). The partition wall has a spatial connection port. The second top compartment has an external wall panel (e.g., the rear, upper panel) located facing the spatial connection port, the external wall panel having a vent (e.g., a gallery) formed therethrough. There is provided a duct-shaped heatsink to deliver outside air introduced through the vent to the spatial connection port. Electric components, such as an inverter, are disposed directly on an external surface of the heatsink (on the top face).
