Container refrigeration unit and method for fabricating the same

摘要

Disclosed is a casing structure by which stiffness of a casing of a container refrigeration unit for cooling the interior of a container can be increased without affecting the arrangement, shape, and maintainability of devices accommodated in the casing. A container interior side of the external casing (12) which constitutes the casing (11) is provided with flanges (34) which extend vertically and which are located at both end portions of the external casing (12) along a dimension of the container width. Each of the flanges (34) has a rectangular cylindrical portion (34a) extending vertically along the external casing (12).
