The invention relates to a metal ceiling panel for a heat radiating ceiling which can be arranged in a coplanar array with like ceiling panels or it can be secured to the upper side of selected metal sheets which are arranged in a coplanar array. The panel of the invention has a central, lengthwise extending broad rib formation defining a channel of part-cylindrical form which is adapted to receive a heating pipe in good heat conducting contact therewith. The rib formation also has portions adapted to receive the ends of a one-piece band used to hold the heating pipe in the channel. The portions of the rib which receive the ends of a one-piece band may have enlarged inner end portions adapted to receive pins inserted at the ends of the panels for aligning the ends of adjoining panels in a line extending parallel to the pipe. The edges of the panels may have a tongue and groove arrangement for engaging adjoining panels. The panels have major surfaces which are substantially flat except for the rib formation extending outwardly from one major surface and optional ribs formed by grooves on the opposite major surface for greater heat dissipation efficiency of the panel. A clip which extends about the pipe has a part circular central section which lies against the pipe, two legs which extend obliquely outwards from the central section and the free ends of the legs extend inwards towards each other to form retaining feet.
A ceiling panel means for a heat radiating ceiling comprising a panel which has oppositely-facing first and second major surfaces and is extruded in one piece from a metal having good heat conduction properties, said first major surface having formed thereon an integral central, lengthwise extending solid broad rib formation defining lengthwise extending channel means of part-cylindrical form having a predetermined radius of curvature, for having seated therein a lengthwise extending pipe conveying a heat transfer fluid, said pipe having an external radius of curvature substantially equal to said predetermined radius of curvature, said solid broad rib formation providing means for retaining a one-piece band extending about said pipe to connect said channel means to said pipe in good heat conducting contact with said panel and providing a broad metal heat conductive path to said second major surface, whereby said panel, when connected to said pipe, radiates heat directly to a space below said second major surface.
A ceiling panel system comprising an array of metal sheets each having major upper and lower surfaces, which sheets are arranged in substantially coplanar relation, and at least two ceiling panels extending parallel to each other, each ceiling panel having oppositely-facing first and second major surfaces and being formed in one piece from a metal having good heat conduction properties, said first major surface having formed thereon a central, lengthwise extending broad rib formation defining lengthwise extending channel means, of part-cylindrical form having a predetermined radius of curvature, for receiving a lengthwise extending pipe conveying a heat transfer fluid, said pipe having an external radius of curvature substantially equal to said predetermined radius of curvature, said broad rib formation providing means for retaining a one-piece band extending about said pipe to connect said channel means to said pipe in good heat conducting contact with said panel, the ceiling panels having their second major surfaces secured in close face-to-face contact with said major upper surfaces of respective sheets of said array.
