Abstract

A method including steps of (1) heating, with a heating system, an apparatus comprising an enclosure assembly and a temperature emulation assembly positioned within said enclosure assembly; (2) thermally isolating said temperature emulation assembly from said heating system with said enclosure assembly; (3) permitting conductive heat transfer to said temperature emulation assembly only through an enclosure assembly-leading end of said enclosure assembly; and (4) representing a hottest temperature and a coldest temperature of an article being emulated by said apparatus with said temperature emulation assembly.

First claim

What is claimed is:

1. A method comprising:
heating, with a heating system, an apparatus comprising an enclosure assembly and a temperature emulation assembly positioned within said enclosure assembly;
thermally isolating said temperature emulation assembly from said heating system with said enclosure assembly;
permitting conductive heat transfer to said temperature emulation assembly, via said enclosure assembly heated by said heating system, only through an enclosure assembly-leading end of said enclosure assembly; and
representing a hottest temperature and a coldest temperature of an article being emulated by said apparatus with said temperature emulation assembly.

2. The method of claim 1 , further comprising assembling said apparatus, comprising:
arranging an inner enclosure within an outer enclosure of the enclosure assembly;
arranging a plurality of thermally conductive plates in a stack within said inner enclosure;
positioning one of said plurality of thermally conductive plates at a stack-leading end in contact with a leading end faceplate of said outer enclosure;
arranging an insulator between outer enclosure-sidewalls of said outer enclosure and inner enclosure-sidewalls of said inner enclosure;
arranging a thermal barrier between an outer enclosure-lagging end faceplate of said outer enclosure and an inner enclosure-lagging end faceplate of said inner enclosure; and
arranging a thermal disruptor between said inner enclosure-sidewalls of said inner enclosure and said stack of said plurality of thermally conductive plates.

3. The method of claim 1 , further comprising:
generating a virtual thermal profile for a thermal model of said article;
generating a virtual thermal profile for a thermal model of said temperature emulation assembly;
comparing said virtual thermal profile for said thermal model of said temperature emulation assembly with said virtual thermal profile for said thermal model of said article; and
reconfiguring said temperature emulation assembly when said virtual thermal profile for said thermal model of said temperature emulation assembly does not match said virtual thermal profile for said thermal model of said article.

4. The method of claim 1 , further comprising inhibiting said conductive heat transfer to said temperature emulation assembly along any conductive heat transfer path except through enclosure assembly-leading end of said enclosure assembly.

5. The method of claim 1 , further comprising inhibiting convective heat transfer to said temperature emulation assembly along any convective heat transfer path.

6. The method of claim 1 , further comprising inhibiting radiative heat transfer to said temperature emulation assembly along any radiative heat transfer path.

7. The method of claim 1 , further comprising measuring temperatures of two locations of said temperature emulation assembly throughout a heating cycle, wherein measured temperatures of said two locations of said temperature emulation assembly represent said hottest temperature and said coldest temperature of said article being emulated by said apparatus.

8. The method of claim 7 , further comprising using said measured temperatures as inputs to control a temperature within said heating system and regulate a temperature of said article being emulated by said apparatus during said heating cycle.

9. The method of claim 8 , further comprising:
generating a thermal profile for said article;
generating a thermal profile of said temperature emulation assembly;
matching a first temperature of said thermal profile of said temperature emulation assembly with a hottest temperature of said thermal profile of said article; and
matching a second temperature of said thermal profile of said temperature emulation assembly with a coldest temperature of said thermal profile of said article, and
wherein said two locations of said temperature emulation assembly are selected to correspond to said first temperature and said second temperature of said thermal profile of said temperature emulation assembly.

10. The method of claim 1 , further comprising conductively transferring heat through said temperature emulation assembly from a temperature emulation assembly-leading end positioned proximate to said enclosure assembly-leading end to a temperature emulation assembly-lagging end.

11. The method of claim 10 , further comprising controlling a rate of said conductive heat transfer through said temperature emulation assembly from said temperature emulation assembly-leading end to said temperature emulation assembly-lagging end of said temperature emulation assembly.

12. The method of claim 10 , further comprising inhibiting convective heat transfer along said temperature emulation assembly from said temperature emulation assembly-leading end to said temperature emulation assembly-lagging end of said temperature emulation assembly.

13. The method of claim 12 , further comprising inhibiting radiative heat transfer along said temperature emulation assembly from said temperature emulation assembly-leading end to said temperature emulation assembly-lagging end of said temperature emulation assembly.

14. A method comprising:
heating, with a heating system, an apparatus comprising:
an enclosure assembly comprising an enclosure assembly-leading end and an opposed enclosure assembly-lagging end; and
a temperature emulation assembly mounted within said enclosure assembly and comprising a temperature emulation assembly-leading end located proximate to said enclosure assembly-leading end and a temperature emulation assembly-lagging end spaced away from said enclosure assembly-lagging end,
wherein said enclosure assembly thermally isolates said temperature emulation assembly and permits conductive heat transfer to said temperature emulation assembly, via said enclosure assembly, only through said enclosure assembly-leading end;

thermally isolating said temperature emulation assembly from said heating system with said enclosure assembly;
permitting conductive heat transfer to said temperature emulation assembly, from said heating system, only through said enclosure assembly-leading end of said enclosure assembly; and
representing a hottest temperature and a coldest temperature of an article being emulated by said apparatus with said temperature emulation assembly.

15. The method of claim 14 , further comprising inhibiting said conductive heat transfer to said temperature emulation assembly along any conductive heat transfer path except through said enclosure assembly-leading end of said enclosure assembly.

16. The method of claim 14 , further comprising inhibiting convective heat transfer to said temperature emulation assembly along any convective heat transfer path.

17. The method of claim 14 , further comprising inhibiting radiative heat transfer to said temperature emulation assembly along any radiative heat transfer path.

18. The method of claim 14 , further comprising measuring temperatures of two locations of said temperature emulation assembly throughout a heating cycle, wherein measured temperatures of said two locations of said temperature emulation assembly represent said hottest temperature and said coldest temperature of said article being emulated by said apparatus.
