Roofing plate with thermal conduction device

Field of application of the invention

The invention relates to a roofing plate, in particular made of concrete or ceramic materials, with a provided on the underside of plate Färmeleitvorrichtung.

Characteristic of the known technical solutions

In a known roofing tile of this type (DE-GM 75 25 656) should be at the bottom of a homogeneous or sufficiently close-meshed layer of good heat conducting material, preferably metal, arranged, which emits the heat generated by solar heat with low thermal resistance to a heat dissipating medium. The heat-removing medium is passed through a channel enclosed by the good heat-conducting material. Thus, each roofing plate includes a channel section which must be tightly connected to the roofed roof with the channel sections of the head and foot side adjacent roofing plate, which is obviously expensive, so that a simple deployment of such roofing panels is not given.

It is known per se that a heat transfer medium leading pipes from the ash cover plates separately attached to the roof structure (DE-OS 27 32 758). Serve here
