The product as performed is characterized by the insertion in the stratified package of thermo-electric conductors to get a thermal control of the stratified package and of the wood board. 2. The wood board according to claim 1 characterized in that the stratified package is composed by two, three or more thermo-insulating materials with smooth surfaces and/or embossed surfaces facing inwards or outwards of the thermo-insulating package, with or without the inclusion of reflective materials. |
CONDUCTORS Technical Field
The current invention deals with a board of natural or composed wood (chipboard, MDF, plywood, oriented strand board, glued laminated timber, etc..) which improves the thermal properties of the original raw material, and it is used in various way as constructive element.
Background Art
The wood boards, known till now, are used in the various constructive elements in the original state, and for this they have the disadvantage of having poor insulating thermal properties.
The invention changes the properties of thermal insulation, through the execution of two (Fig. 1) or more cuts (Fig. 2) along the longitudinal direction of the bar and the insertion of a stratified package (Fig. 10 letter A) of thermal insulating materials.
Disclosure of the invention
The cuts truncate the cohesion of wood fibres producing a discontinuity which reduces the thermal conductivity. Reference terminology:
■ Length of cut: longitudinal direction of the bar;
■ Width of cut: transverse direction perpendicular to the surface of the bar;
■ Depth of cut: transverse direction parallel to the surface of the bar.
The surface of thermal insulating materials used in the stratified composed package can be striped, and/or dotted, and/or squared, and/or thumb etc.. .
The wood board are made from two (Fig. 1) or more incisions (Fig. 2) along the longitudinal direction, continuous and/or discontinuous, belonging to plans that are parallel to each other (Fig. 1 and 3) and/or inclined (Fig. 4).
The single incision lies on a plane that is parallel (Fig. 1 and 2) and/or inclined
(Fig. 3 and 4) compared to the different surfaces of the bar.
The cut of a surface is long as the entire wood board (Fig. 5) or it is formed by several cracks (Fig. 6) of different length, width and height, belonging to the same plane (Fig. 6), and/or to several planes parallel to each other (Fig. 7) and/or to several planes inclined to each other (Fig. 8).
The height of the cracks of the wood bar has equal or unequal thickness compared with the height of the cuts made on the same side and/or on different sides of the wood bar.
The width of the cracks of the wood bar has equal or unequal depth compared with the width of the cuts made on the same side and/or on different sides of the wood bar.
In the created cracks it is inserted a stratified package of two, three or more thermal insulating materials with smooth surface (Fig. 14 letter D) and/or with rough surface (Fig. 16 letter C).
The rough surface of the thermal insulating material is turned outwards or inwards of the stratified package.
The rough surface of the thermal insulating material is turned outwards of the stratified package to reduce the contact area between the wood and thermal insulating package inserted in the cuts, reducing the heat transmitted by conduction.
The rough surface of the thermal insulating material is turned inwards of the stratified package to reduce the contact area between the materials of the thermal insulating package, reducing the heat transmitted by conduction. The thermal stratified package, as performed, is inserted in the cuts made in the wood (Fig. 10 beds. A).
The stratified package can contain one or more layers of reflective material (Fig. 11, 12, 13 and 14 letter B), to reflect the heat back to the source, or to help reducing the leakage of heat from inside the building to outside, or to prevent the entry of the heat from outside the building to the interior.
To obtain a variable thermal control of the thermal insulating package, thermoelectric conductors are added in the stratified package (Fig. 15 beds. E), adding or replaced the the reflective layer. This system introduces an active thermal control of the stratified thermal insulating package. The stratified package is inserted in the cuts made in the wood board. The width of the cuts made on wood is variable; the size of the cuts or canal (Fig. 1 and 2) are proportional to the degree of thermal resistance that you want to obtain and to the section of wood manufactured. The scope of this invention is the building sector, and it can be used both as a finite element (Fig. 10) and as a structural component, and as support for other elements.
The wood board is workable to obtain frames (Fig. 10) and other products.
The wooden board is used individually (Fig. 5), or it is assembled in a modular way (Fig. 9), matching the various elements to form a continuous wood panel.
