Abstract

A method of forming a wick assembly is disclosed including positioning an inner ring in a first wick, positioning the inner ring in a second wick, abutting an end of the first wick with an end of the second wick, positioning an outer ring about a portion of the first wick and a portion of the second wick, positioning a mandrel within the inner ring, positioning a die about the outer ring, and applying a force to the die, wherein the force couples the outer ring, the inner ring, the first wick, and the second wick together to form the wick assembly.

Claims (60)

1. A method of forming a wick assembly, the method comprising:

positioning an inner ring in a first wick;

positioning the inner ring in a second wick;

abutting an end of the first wick with an end of the second wick;

positioning an outer ring about a portion of the first wick and a portion of the second wick;

positioning a mandrel within the inner ring;

positioning a die about the outer ring; and

applying a force to the die, wherein the force couples the outer ring, the inner ring, the first wick, and the second wick together to form the wick assembly.

2. The method of claim 1 , further comprising removing the die from the wick assembly.

3. The method of claim 2 , further comprising diffusion bonding the wick assembly.

4. The method of claim 1 , further comprising removing the mandrel from the wick assembly.

5. The method of claim 1 , further comprising:

defining a first edge at the end of the first wick, wherein the first edge is perpendicular to the length of the first wick; and

defining a second edge at the end of the second wick, wherein the second edge is perpendicular to the length of the second wick;

wherein abutting the end of the first wick with the end of the second wick comprises abutting the first edge at the end of the first wick with the second edge at the end of the second wick.

6. The method of claim 1 , further comprising:

defining first fingers at the end of the first wick; and

defining second fingers at the end of the second wick;

wherein abutting the end of the first wick with the end of the second wick comprises interlacing the first fingers with the second fingers.

7. A method of preparing a heat pipe, the method comprising:

forming a wick assembly, comprising:

positioning an inner ring in a first wick;

positioning the inner ring in a second wick;

positioning an outer ring about a portion of the first wick and a portion of the second wick;

positioning a die about the outer ring; and

applying a force to the die, wherein the force couples the outer ring, the inner ring, the first wick, and the second wick together to form the wick assembly,

diffusion bonding the wick assembly; and

positioning the diffusion bonded wick assembly in the heat pipe.

8. The method of claim 7 , further comprising positioning a mandrel within inner ring prior to applying the force to the die.

9. The method of claim 8 , further comprising removing the mandrel from the wick assembly after applying the force to the die.

10. The method of claim 7 , wherein forming the wick assembly further comprises abutting an end of the first wick with an end of the second wick.

11. The method of claim 10 , further comprising:

defining a first edge at the end of the first wick, wherein the first edge is perpendicular to the length of the first wick; and

defining a second edge at the end of the second wick, wherein the second edge is perpendicular to the length of the second wick;

wherein abutting the end of the first wick with the end of the second wick comprises abutting the first edge at the end of the first wick with the second edge at the end of the second wick.

12. The method of claim 10 , further comprising:

defining first fingers at the end of the first wick; and

defining second fingers at the end of the second wick;

wherein abutting the end of the first wick with the end of the second wick comprises interlacing the first fingers with the second fingers.

13. A method of forming a wick assembly, the method comprising:

positioning an inner ring in a first wick comprising a first characteristic;

positioning the inner ring in a second wick comprising a second characteristic, wherein the second characteristic is different than the first characteristic;

abutting an end of the first wick with an end of the second wick;

positioning an outer ring about a portion of the first wick and a portion of the second wick;

positioning a mandrel within the inner ring;

positioning a die about the outer ring; and

applying a force to the die, wherein the force couples the outer ring, the inner ring, the first wick, and the second wick together to form the wick assembly.

14. The method of claim 13 , further comprising removing the die from the wick assembly.

15. The method of claim 14 , further comprising diffusion bonding the wick assembly.

16. The method of claim 13 , wherein the first characteristic comprises a material of the first wick and the second characteristic comprises a material of the second wick.

17. The method of claim 13 , wherein the first characteristic comprises a length of the first wick and the second characteristic comprises a length of the second wick.

18. The method of claim 13 , wherein the first characteristic comprises a porosity of the first wick and the second characteristic comprises a porosity of the second wick.

19. The method of claim 13 , further comprising:

defining a first edge at the end of the first wick, wherein the first edge is perpendicular to the length of the first wick; and

defining a second edge at the end of the second wick, wherein the second edge is perpendicular to the length of the second wick;

wherein abutting the end of the first wick with the end of the second wick comprises abutting the first edge at the end of the first wick with the second edge at the end of the second wick.

20. The method of claim 13 , further comprising:

defining first fingers at the end of the first wick; and

defining second fingers at the end of the second wick;

wherein abutting the end of the first wick with the end of the second wick comprises interlacing the first fingers with the second fingers.
