Lightweight heat-conducting plates of compressed expanded graphite material have layer planes which are preferably disposed so as to be parallel to the surface so that heat conduction in a lateral direction is preferred to heat conduction perpendicular to the plate plane. The heat-conducting plates are suitable for the transmission of heat of floor-heating, wall-heating, ceiling-heating and other flatly disposed heating systems and air-conditioning ceilings, for the transmission of heat and the dissipation of heat in buildings, automobiles, machines, installations and containers. The heat-conducting plates are dimensionally stable without the addition of binder and aggregates and can be produced in a continuous process. A composite component having at least one heat-conducting plate and a method for production of heat-conducting plates are also provided.

Heat-conducting plate of expanded graphite, composite and method for production

Die Erfindung betrifft Warmeleitplatten aus verdichtetem Graphitexpandat, dessen Schichtebenen bevorzugt parallel zur Flache angeordnet sind, so dass die Warmeleitung in lateraler Richtung gegenuber der Warmeleitung senkrecht zur Plattenebene bevorzugt ist. Die erfindungsgemasen Warmeleitplatten sind geeignet zur Warmeubertragung von Fusboden-, Wand-, Decken- u.a. flachig angeordneten Heizungen, Klimadecken, zur Warmeubertragung und Warmeabfuhr in Gebauden, Automobilen, in Maschinen und Anlagen und Behaltern. Die Warmeleitplatten sind ohne Zusatz von Binder und Zuschlagstoffen formstabil und konnen in einem kontinuierlichen Verfahren hergestellt werden.

Production and drying of thick walled components comprises using micro-fine flexible hot conductors made from thin metal foils of less than 0.6 mm thickness as energy source. The components molded from a wet molding composition are heated to 500 deg C or more and dried. Preferred Features: The metal foils have a thickness of 0.04-0.5 mm and are made from sheet metal, steel or high grade steel having an ohmic resistance of 0.1-1.5 ohm/m. The energy source is operated with a voltage of 2-70 V.

The current-conducting materials are operable as electrical resistance heating and on the contact and binding layer (2) is adhered a cover layer (5) comprising a heat-conducting plate-shaped lining. As a support plate, a vacuumed vacuum heat insulating plate is provided with a vacuum-tight casing of refined steel plate and filled with a microporous heat insulating material. The vacuum heat insulating plate has a heat conductivity in accordance with German Industrial Standard DIN 52612 of less than 0.01 W/mK. The support plates have a thickness of 10-40 mm and as heat insulating material contain micro-glass fibres, powder-form inorganic oxide, micro-silica and/or infusorial earth.

Flat insulating material has pressure supporting points in the form of supporting parts made of a material of high compression strength and good thermal insulating properties arranged at a specified distance in the insulating material. Preferred Features: The supporting parts are inserted, pressed or adhered into the flat insulating material from the upper to the lower side through holes. The supporting parts are made of porcelain, stone, mullite, aluminum oxide, zirconium silicate, zirconium mullite or zirconium corundum.

The apparatus is intended for drying large monolithic components which consist of concrete or refractive materials and are formed of a wet mass with use of a mould. Introduced into the mould, this mass (concrete, porous concrete, high density concrete etc.) is compacted, dried and possibly sintered. An energy source capable of producing heat energy is inserted into the mould so that it is located at the centre component to be produced.
