Liquid-cooled-type cooling device

摘要

A liquid-cooled-type cooling device includes a casing (2) which has a cooling-liquid inlet (11) formed at a rear end portion of the casing and a cooling-liquid outlet (12) formed at a front end portion of the casing. A corrugated fin (17) for forming a plurality of flow channels through which a cooling liquid flows from the rear side toward the front side is disposed within the casing (2) to be located between the cooling-liquid inlet and the cooling-liquid outlet. A heat-generating-body mounting region is provided on an outer surface of a top wall (3) of the casing. Projections (23A, 23B) which come into contact with front and rear end portions of the corrugated fin (17) to thereby position the corrugated fin in the front-rear direction are provided on an inner surface of the bottom wall (4) of the casing at positions shifted, in the left-right direction, from an inner surface region corresponding to the heat-generating-body mounting region.
