Engine generator

摘要

An engine generator (10) comprises a fan cover (78) made of die-cast aluminum alloy, and a power control unit including an aluminum base sheet (91). The base sheet (91) has a power control circuit (95) formed thereon. The fan cover (78) includes a mounting portion (114) to be attached to the power control unit. When the power control unit is attached to the fan cover (78), a surface (112) of the aluminum base sheet (91) comes into intimate contact with an outer surface (113) of the mounting portion (114). Heat generated at the unit is transmitted to the fan cover (78), and then released from the fan cover (78) serving as a heat releasing member. <IMAGE>
