Abstract
A water-cooled housing (100) comprises: a tubular passage section (20) which has a plurality of partition walls erected in the direction of the central axis at a prescribed angular interval on a substantially cylindrical inner wall to form a plurality of outward passages and a plurality of inward passages extending parallel to each other along the central axis between the plurality of partition walls and the outer peripheral surface of a motor (40); a first cover section (10) which closes a first opening of the tubular passage section (20) while having a plurality of returning passages that connects inward passages to next outward passages; a second cover section (30) which closes a second opening of the tubular passage section (20) while having a plurality of returning passages that connects outward passages to next inward passages; a water supply section (16a) which is provided on the first cover section (10) and connected to the entrance of a first outward passage; and a water drain section (17a) which is connected to the outlet of the last inward passage of the first cover section (10) or is connected to the outlet of the last outward passage of the second cover section (30).
