Abstract

The invention relates to a test system for cooling and/or heating at least one test piece comprising a platform, at least one heating and/or cooling fluid providing means coupled to the platform, at least one position means for reproducibly fixing the relative position of the fluid providing means to the at least one test piece and wherein the at least one position means is connected to the platform, the platform comprising at least one fastening means, in particular two openings for releasable coupling the fluid providing means for an at least temporarily fixing of the relative position of the fluid proving means to the test piece. It also relates to a test method.

First claim

The invention claimed is:

1. A test system for at least one chosen from cooling and heating a test piece comprising:
a platform,
a fluid conduit for providing at least one chosen from a heating fluid and a cooling fluid,
a positioning device coupling the fluid conduit to the platform for adjustably fixing a relative position of the fluid conduit with respect to the test piece; and
wherein the platform comprises a fastening device including two openings and the positioning device is connected to the platform via at least one of the two openings for adjustably coupling the fluid conduit to the platform for providing the adjustable fixing;
wherein at least one chosen from the platform and the positioning device includes at least one chosen from a marking and a grating for indicating a relative position of the position device with respect to the at least one of the two openings.

2. The test system according to claim 1 , wherein the at least one chosen from the heating fluid and the cooling fluid comprises at least one chosen from hot air, cool air, nitrogen and a liquid.

3. The test system according to claim 2 , wherein the liquid is water or oil.

4. The test system according to claim 1 , wherein the platform comprises an opening including a circular circumference in which the test piece is positionable to leave a portion of the test piece open to the fluid conduit.

5. The test system according to claim 1 , wherein the at least one chosen from the two openings includes an arc-shaped portion.

6. The test system according to claim 1 , and further comprising a fluid dissipating nozzle coupled to the fluid conduit.

7. The test system according to claim 6 , and further comprising a machine device for adjusting or fixing a spatial position of at least one chosen from the nozzle and the fluid conduit.

8. The test system according to claim 7 , and further comprising a temperature measurement sensor for measuring a temperature of the test piece and controlling the adjusting or fixing by the machine device based on the measured temperature of the test piece.

9. The test system according to claim 1 , wherein the fluid conduit is adjustably mounted to the positioning device to adjustably fix at least one chosen from a linear distance of the fluid conduit to the test piece and an angular position of the fluid conduit relative to the test piece.

10. The test system according to claim 1 , and further comprising a valve for adjusting a flow of the at least one chosen from the heating fluid and the cooling fluid.

11. The test system according to claim 10 , wherein the valve is a manually controlled valve.

12. The test system according to claim 10 , wherein the valve is an automatically controlled valve.

13. A method for testing a test piece under controlled thermal conditions, wherein:
a) providing a fluid conduit for providing at least one chosen from a heating fluid and a cooling fluid and providing that the fluid conduit is coupled to a platform,
b) releasably fixing a relative position of the fluid conduit with respect to the test piece with a positioning device wherein the positioning device is connected to the platform, the platform comprising a fastening device including two openings for releasably coupling the fluid conduit for providing the releasable fixing,
c) supplying the at least one chosen from the heating fluid and the cooling fluid through the fluid conduit to the test piece,
providing at least one chosen from the fluid conduit and the position device with at least one chosen from a marking and a grating for indicating at least one chosen from a linear position and an angular position of the fluid conduit with respect to the position device and using the at least one chosen from the linear position and the angular position to accurately position the fluid conduit with respect to the position device.

14. The method according to claim 13 , and further comprising achieving at least one chosen from a predetermined temperature profile and a spatial temperature profile in the test piece via the supplying the at least one chosen from the heating fluid and the cooling fluid through the fluid conduit to the test piece.

15. A test system for at least one chosen from cooling and heating a test piece comprising:
a platform,
a fluid conduit for providing at least one chosen from a heating fluid and a cooling fluid,
a positioning device coupling the fluid conduit to the platform for adjustably fixing a relative position of the fluid conduit with respect to the test piece; and
wherein the platform comprises a fastening device including two openings and the positioning device is connected to the platform via at least one of the two openings for adjustably coupling the fluid conduit to the platform for providing the adjustable fixing;
wherein at least one chosen from the fluid conduit and the position device includes at least one chosen from a marking and a grating for indicating at least one chosen from a linear position and an angular position of the fluid conduit with respect to the position device.
