FULLY CLOSED HORIZONTAL DYNAMO-ELECTRIC MACHINE

WIPO Patent Application WO/2012/001757

A1

A fully closed horizontal dynamo-electric machine is configured in such a manner that a rotor (5) and a stator (3), which are horizontally disposed, are contained in an airtight manner in a body frame (2), a refrigerant gas (10) sealed within the body frame (2) circulates through a refrigerant flow path to cool the rotator (5) and the stator (3), and water-cooled heat exchangers (11) for cooling the refrigerant gas (10) is provided in the middle of the refrigerant flow path. In a view of a side face of the dynamo-electric machine viewed in the direction perpendicular to the axis (6) of the rotor (5), the heat exchangers (11) are vertically disposed at positions near both the left and right ends of the body frame (2) on the front face side thereof and at positions near both the left and right ends of the body frame (2) on the rear face side thereof, and water supply openings (11b) and water discharge openings (11c) for the cooling water are provided on the upper side of the heat exchangers (11).
