Thermal insulation/thermal collector assembly

DETAILED DESCRIPTION 1.
Purposes of the Invention It is an object of the present invention to improve an integrated thermally insulating arrangement of the kind initially recited such that it can be produced economically and such that an effective, durable thermally insulating arrangement is produced, which results in high collections of solar energy and low thermal losses at times of low outside temperatures while, at times of high outside temperatures, the acceptance of solar radiation energy is decreased.
These and other objects and advantages of the present invention will become evident from the description which follows.

Brief Description of the Invention The application of a particularly simple construction of the thermally insulating layer of thin elements allows the formation of simply produced open channels, having throughout a uniform internal diameter, which are well suited in like manner for the transfer of the radiation, the diffusion of humidity, and for the obtaining of a high mechanical strength under low use of material.
In this context, the use of particularly structured and, in particular, of wavy sheets of thermally insulating material, and preferably with the intermediate positioning of planar sheets of the same material are simple to process and result in a well-stiffened structure of the thermally insulating layer with channels of uniform diameter and a small diameter in comparison to the thickness of the thermally insulating layer, and this allows an economically favorable mass production using materials available at economically favorable conditions.
The thin elements forming the individual layers in the corrugated cardboard are in each case disposed at a layer distance from each other of from 1 to 20 mm, and preferably of from 3 to 10 mm.
The thickness of the sheets should amount to 0.
1 mm-2 mm.
The diameter, which in fact is designated as "lumen" because of the non-circular cross-section of the channels, amounts to 1 mm to 20 mm.
The ratio of the thickness of the sheets to the diameter of the channel width is not to be larger than 1:10
