A ceiling or wall unit comprises a plurality of juxtaposed aluminum plates, whereby one rim of each plate is optionally inserted in a groove of an abutting plate. According to the invention, each aluminum plate is provided with at least one cooling pipe shaped integral with the plate, inner longitudinal ribs being provided in the cooling pipe. In this manner the plate can be used for cooling a room, the temperature of which is too high on account of the outdoor temperature or heat-producing machines, the lighting or like equipment. The inner longitudinal ribs of the cooling pipes increase the inner surface of the cooling pipes whereby the dimensions of the pipes and consequently of the plates can be correspondingly reduced. |
