Abstract

A method of manufacturing a heat transfer system is provided that includes, in one form, preparing a heat conducting array by perforating at least a portion of the heat conducting array, placing the heat conducting array around foam elements, placing a heat conducting spreader along one surface area of the foam elements, placing a lower skin over the heat conducting spreader, placing an upper skin over an opposite surface area of the foam elements to create a structural assembly, and curing the structural assembly. A material of the foam elements flows through the perforated portion of the heat conducting array during the curing step.

Claims (37)

1. A method of manufacturing a heat transfer system comprising:

preparing a heat conducting array by perforating at least a portion of the heat conducting array;

placing the heat conducting array around foam elements;

placing a heat conducting spreader along one surface area of the foam elements;

placing a lower skin over the heat conducting spreader;

placing an upper skin over an opposite surface area of the foam elements to create a structural assembly; and

curing the structural assembly by a vacuum autoclave,

wherein a material of the foam elements flows through the perforated portion of the heat conducting array during the curing step.

2. The method according to claim 1 , wherein the heat conducting array is a pyrolytic graphite sheet (PGS) material.

3. The method according to claim 1 , wherein the heat conducting spreader is a pyrolytic graphite sheet (PGS) material.

4. The method according to claim 1 , wherein the heat conducting array defines at least one upper cap, at least one lower cap, and a wall portion extending between at least one upper cap and at least one lower cap when placed around the foam elements, and the wall portion is perforated.

5. The method according to claim 1 further comprising applying a moisture-proof layer over the upper skin.

6. The method according to claim 5 , wherein the moisture-proof layer is an ethylene-co-methacrylic acid (EMAA) material.

7. A method of manufacturing a heat transfer system comprising:

preparing a heat conducting array by perforating at least a portion of the heat conducting array, the heat conducting array comprising a pyrolytic graphite sheet (PGS) material;

placing the heat conducting array around foam elements;

placing a heat conducting spreader along one surface area of the foam elements, the heat conducting spreader comprising a pyrolytic graphite sheet (PGS) material;

placing a lower skin over the heat conducting spreader;

placing an upper skin over an opposite surface area of the foam elements to create a structural assembly; and

curing the structural assembly by a vacuum autoclave,

wherein a material of the foam elements flows through the perforated portion of the heat conducting array during the curing step.

8. The method according to claim 7 , wherein the heat conducting array defines at least one upper cap, at least one lower cap, and a wall portion extending between at least one upper cap and at least one lower cap when placed around the foam elements, and the wall portion is perforated.

9. The method according to claim 7 further comprising applying a moisture-proof layer over the upper skin.

10. The method according to claim 9 , wherein the moisture-proof layer is an ethylene-co-methacrylic acid (EMAA) material.

11. A method of manufacturing a heat transfer system comprising:

preparing a heat conducting array by perforating at least a portion of the heat conducting array;

placing the heat conducting array around foam elements;

placing a lower skin over one surface area of the foam elements;

placing an upper skin over an opposite surface area of the foam elements to create a structural assembly; and

forming the structural assembly under heat and pressure,

wherein a material of the foam elements extends through the perforated portion of the heat conducting array during the forming step.

12. The method according to claim 11 , wherein the heat conducting array is a pyrolytic graphite sheet (PGS) material.

13. The method according to claim 11 further comprising placing a heat conducting spreader between the lower skin and the core elements.

14. The method according to claim 13 , wherein the heat conducting spreader is a pyrolytic graphite sheet (PGS) material.

15. The method according to claim 11 , wherein the heat conducting array defines at least one upper cap, at least one lower cap, and a wall portion extending between at least one upper cap and at least one lower cap when placed around the core elements, and the wall portion is perforated.

16. The method according to claim 11 , wherein the structural assembly is cured in a vacuum autoclave.

17. The method according to claim 11 , wherein the structural assembly is formed in a press.
