HOT HF COMPONENT WITH HF CAVITY

Abstract

A hot HF component equipped with an HF cavity which is delimited by a jacket includes at least one internal protrusion, the jacket comprising at least one internal canal following the contour of its internal surface to allow the flow of a heat transport fluid intended to remove heat energy originating from the cavity.

Claims

1. A hot HF component equipped with a plurality of HF cavities which is delimited by a jacket comprising at least one internal protrusion, said jacket comprising at least one internal canal following the contour of its internal surface to allow the flow of a heat transport fluid intended to remove heat energy originating from the cavity.

2. The hot HF component as claimed in claim 1, wherein an internal canal is flush with the internal surface of the jacket.

3. The hot HF component as claimed in claim 1, wherein an internal protrusion is a lip or an iris.

4. The hot HF component as claimed in claim 1, wherein the external part of the portions of the internal canal on the outside of the internal protrusions comprises an external cover layer.

Description

[0023] The invention will be better understood by studying a number of embodiments described by way of entirely nonlimiting examples and illustrated by the attached drawing in which:

[0024] FIG. 1 schematically illustrates a hot HF component equipped with an HF cavity, according to the prior art;

[0025] FIG. 2 schematically illustrates a hot HF component equipped with an HF cavity, viewed in section, according to the prior art;

[0026] FIG. 3 schematically illustrates a hot HF component equipped with an HF cavity, viewed in section, with iris-like internal protrusions, according to the prior art;

[0027] FIG. 4 schematically illustrates a hot HF component equipped with an HF cavity, viewed in section, with lip-like internal protrusions, according to the prior art;

[0028] FIG. 5 schematically illustrates a hot HF component equipped with an HF cavity, viewed in section, according to one aspect of the invention; and

[0029] FIG. 6 schematically illustrates a hot HF component equipped with an HF cavity, viewed in section, according to another aspect of the invention.

[0030] Across all of the figures, elements that have identical references are similar.

[0031] FIG. 5 illustrates, according to one aspect of the invention, a hot HF component 1 equipped with an HF cavity 4 which is delimited by a jacket 3 comprising at least one internal protrusion 5. The jacket 3 comprises at least one internal canal 6 following the contour of its internal surface 7 to allow the flow of a heat transport fluid intended to remove heat energy originating from the cavity 4.

[0032] The internal canal 6 is flush with the internal surface 7 of the jacket 3.

[0033] What is meant by an internal canal 6 flush with the internal surface 7 of the jacket 3 is that part of the wall of the internal canal 6 forms part of the internal surface 7 of the protrusion. Its thickness is configured to take account of the mechanical stresses it is called upon to withstand.

[0034] An internal protrusion 5 may be a lip or an iris.

[0035] FIG. 6 illustrates, according to one aspect of the invention, a hot HF component 1 equipped with an HF cavity 4 which is delimited by a jacket 3 comprising at least one internal protrusion 5. The jacket 3 comprises at least one internal canal 6 following the contour of its internal surface 7 to allow the flow of a heat transport fluid intended to remove heat energy originating from the cavity 4. The external part of the portions of the canal 6 on the outside of the internal protrusions 5 comprises an external cover layer 8.

[0036] The present invention allows the cavity to be cooled as close as possible to its surface, thereby making it possible to significantly improve the cooling of the hottest regions.
