摘要:
In a cabinet, an inverter housing is mounted on an inverter housing mounting surface. Heat-exchanger-side pipe connection ports 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 are disposed so as to extend on a controller mounting side. A refrigerant supply line 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.

摘要:
A cast cylinder head 1 of an internal combustion engine to be mounted on a vehicle has an intake-side side wall 2i, an exhaust-side side wall 2e, and opposite end walls 3r and 3f. The walls 2i, 2e, 3r and 3f define a water jacket 8. A first cooling water exit part 11 and a second cooling water exit part 21 both having a solid structure are formed by casting integrally with one of the intake-side side wall 2i and the exhaust-side side wall 2e and with one of the end walls 3r and 3f, respectively. Cooling water exit openings 15,16 or 25,26 opening into the water jacket 8 are drilled selectively in either of the first cooling water exit part 11 and the second cooling water exit part 21 depending on the engine mounting position on the vehicle. Thus the same cylinder head can be used independently of the mounting orientation of the engine on the vehicle.
