#CMT# #/CMT# The device (1) has a cover layer (3) extending over a surface (8) of a base layer (2). A heating element (4) is inserted in the base and cover layers to provide thermal energy (9) over a bottom surface (11) of the cover layer. The base and cover layers comprise a support material (5). Insert elements (6) i.e. aluminum grit, with high thermal conductivity are arranged in the support material. The insert elements are arranged in the cover layer and/or a region of the base layer between the heating element and the cover layer. #CMT#USE : #/CMT# Floor heating device for a rail vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The insert elements are arranged in the support material, thus reducing weight of the device without adversely affecting homogeneous heat distribution on a floor area, while enhancing heat transmission by the heating element, preventing heat emission downward to a chassis to a large extent and obviating voltages at junctions between the base and cover layers. The insert elements are arranged in the cover layer and/or the region of the base layer between the heating element and the cover layer, thus achieving efficient heat flow to the cover layer and/or to the floor area, while preventing heat flow into the covering layer in an opposite direction. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of a floor heating device for a rail vehicle. 1 : Floor heating device 2 : Base layer 3 : Cover layer 4 : Heating element 5 : Support material 6 : Insert elements 8 : Surface of base layer 9 : Thermal energy 11 : Bottom surface of cover layer #CMT#METALLURGY : #/CMT# The insert elements are made of aluminum and/or copper. #CMT#POLYMERS : #/CMT# The support material is made of plastic, glass-fiber reinforced plastic and curable resin. The device comprises a stabilization layer made of glass-fiber reinforced plastic. |
