Abstract

Systems. materials. and methods for heat management and protecting a manufactured article or surface from thermal damage. The protective materials have heat absorbing elements comprised of a metastable or a thermally stable material. The materials include particles with high thermal conductivity. thermally conductive protrusions or patterns. heat absorbing matrices or layers, or a combination thereof. The materials can be applied to an article to prevent or reduce thermal damage.

First claim

1 . A protective material for heat management and protecting an article from thermal damage, the protective material comprising heat absorbing elements, wherein the heat absorbing elements are comprised of a metastable or a thermally stable material.

2 . The protective material of claim 1 , further comprising a heat absorbing matrix having heat dissipating pathways and insulating spacers between said pathways, wherein the heat absorbing elements are disposed on or at least a portion thereof is embedded within the heat absorbing matrix, wherein the heat absorbing matrix is configured to separate the heat absorbing elements from each other.

3 . (canceled)

4 . The protective material of claim 2 , wherein the insulating spacers vary in size.

5 . The protective material of claim 4 , wherein the insulating spacers are larger closer to the heat absorbing elements and smaller further away from the heat absorbing elements.

6 . The protective material of claim 2 , wherein the pathways are narrower in size further away from the heat absorbing elements and thicker closer to the heat absorbing elements.

7 . The protective material of claim 2 , further comprising a separator that physically separates the heat absorbing elements from the heat absorbing matrix.

8 . The protective material of claim 2 , wherein the material is adapted to be applied on at least a portion of the article, wherein the heat absorbing matrix separates the heat absorbing elements from the article such that the heat absorbing elements are further away from the article.

9 . The protective material of claim 1 , wherein the heat absorbing elements have anisotropic thermal conductivity.

10 . The protective material of claim 9 , wherein the heat absorbing elements direct heat along a specific path that is longer or more difficult as compared to a traditional conductive path.

11 . The protective material of claim 9 , wherein the heat absorbing elements direct heat in a desired path, wherein the heat absorbing elements absorbs heat and guides it in a direction away from the article.

12 . The protective material of claim 1 , wherein the heat absorbing elements have isotropic thermal conductivity.

13 - 15 . (canceled)

16 . The protective material of claim 1 , wherein the heat absorbing elements are crystalline or amorphous.

17 - 19 . (canceled)

20 . The protective material of claim 1 , wherein the heat absorbing elements are configured to undergo degradation, dehydration or other physical or chemical processes to dissipate heat.

21 . (canceled).

22 . The protective material of claim 1 , wherein the heat absorbing elements are configured to be applied onto the article such that they propagate heat in a direction away from the article.

23 - 24 . (Canceled)

25 . The protective material of claim 2 , wherein the heat absorbing elements and the heat absorbing matrix are arranged concentrically to form cylindrical structures that propagate heat in a specific direction or to a specific area.

26 - 27 . (Canceled)

28 . The protective material of claim 1 , wherein the heat absorbing elements are protrusions projecting from the article.

29 . The protective material of claim 1 , further comprising a heat sink layer.

30 . The protective material of claim 1 , wherein the heat absorbing elements are thermally coupled to the heat sink layer.

31 - 37 . (Canceled)

38 . A protective material for heat management and protecting an article from thermal damage, the protective material comprising a heat absorbing layer disposed on the article, and thermally conductive protrusions that are dispersed on or in contact with the heat absorbing layer.

39 - 45 . (canceled)

46 . A method of preventing or reducing thermal damage to an article, the method comprising:
a. applying a heat absorbing layer protective material on a surface of the article; and b. applying thermally conductive protrusions on an opposing surface of the article such that the thermally conductive protrusions are disposed through the article and are in contact with the heat absorbing layer.

47 - 54 . (canceled)
