The subject of the invention is metal panel with emitting and absorptive characteristics, specifically heating and cooling panel, used in particular in apparatus where heat energy is conveyed from fluids flowing in the heating or cooling systems. The key characteristic of the panel as proposed by the invention, stems from the fact that it consists of at least one heat pipe channel (2) which has a polygon shaped cross section, which is connected with the intermediate layer (1) on the outer surface (20), above which there protrudes the outer surface (20) of the heat pipe channel (2) formed by stamping. The heat pipe channel (2) has at least one longitudinal conduit (3) for condensate on its inner surface. The intermediate layer (1) between the heat pipe channels (2) has holes (4) punched out. Along one of the two longer edges (5) of the intermediate layer (1) there is a strip (6) which has width of (a), and which is bent in an S-shaped form, parallel to the plane of the intermediate layer (1), whereas at a distance equal to (a) from the other longer edge (5) there is parallel rim (7), which has a limiter (8) in form of a flange, with the height matching that of the strip's thickness (6), specifically L-shaped element (9) projecting towards the closer edge (5). The thickness (g) of the intermediate layer (1) is less than 0.25 of the cross section height (h) of the heat pipe channel (2) and / or is less than 0.01 of the distance (b) between the longer edges (5). The intermediate layer (1) is curved. The heat pipe channels (2) are on both sides of the intermediate layer (1). On at least one of the outer surface of the heat pipe channel there are two protrusions with a dent between them. The composition of the panel allows it to be immersed in ceramic material during production of thin wallboards to be used for indoor dry lining works in residential and office building, providing heating or cooling functions, in wall heating systems or as structural elements of heat tanks, where it is essential to transmit and absorb heat without interspersing the layers of fluids with stabilized temperature distribution. |
