STRUCTURAL ELEMENT FOR SURFACE HEATING AND COOLING SYSTEMS AND PROCESS FOR MANUFACTURING SUCH ELEMENTS

摘要

A structural element for surface heating and cooling systems in the form of a self-supporting sandwich construction with a stable heat-conducting plate (501) forming the top flange and a lower stable plate (502) bonded in a shear-resistant manner to the heat-conducting plate through a heat-insulating layer (504) made of a suitable plastics material, preferably polyurethane foam. Heat-transfer channels (503) with heat-conducting connections are located on the lower surface of the heat-conducting plate (501) to which they are bonded. A process for the manufacture of such structural elements is proposed, in which the profiles forming the heat-transfer channels (503) are secured to the lower surface of the upper heat-conducting plate (501) by the pressure of a heat-insulating layer (504) foamed under lateral sealing into the space between the upper and lower plates (501 and 502) supported externally and kept a certain distance apart.
