PANEL FOR FLOOR HEATING

PURPOSE:To achieve uniform temp. distribution by a method wherein the air in a cylindrical body of each flow element is sealed up tightly between a flat plate for the lower plate and the element to act as a heat insulating layer and projections placed at the closed end parts of the cylindrical body provide a fluid passage between the outer wall of the closed part and a flat plate for the upper plate. CONSTITUTION:Each flow element 20 enables its outer wall of a cylindrical body 21 to adhere each other and its open end part to adhere on a flat plate 10 for the lower plate. The upper part side of the element 20 fixes a flat plate 30 for the upper plate by using projections 22. By this constitution, a heat insulating layer 23 is formed by sealed air between each element 20 and the plate 10 and a fluid passage provided by the projections 22 is formed between the outer wall of a closed end part and the flat plate 30. As the projections 22 are located with various relative angles and arrangements in the fluid passage, the fluid is branched off in various directions by the projections 22. As a result, a labyrinth-shaped passage is formed and as the fluid flows complicatedly in the overall region of a panel, uniform temp. distribution is obtained.
