Abstract
A modular magnetron for use in UV curing lamp assembly is disclosed. The modular magnetron includes a vacuum tube having a vacuum tube body, a top assembly, and a bottom assembly. The top assembly is configured to substantially overlay the vacuum tube. The bottom assembly is configured to substantially extend about the vacuum tube, the vacuum tube being positioned to partially protrude from the bottom assembly, the bottom assembly including a cooling assembly configured to employ a flexible clamp-type fitting about the vacuum tube body for substantially maintaining thermal and electrical conductivity. The top assembly is configured to be releasably fastened to the bottom assembly about the vacuum tube with removable fasteners.
Claims17
A modular magnetron for use in an ultraviolet radiation (UV) curing lamp assembly, comprising:
- a vacuum tube having a vacuum tube body;
- a top assembly configured to substantially overlay the vacuum tube;
- and
- a bottom assembly configured to substantially extend about the vacuum tube, the vacuum tube being positioned to partially protrude from the bottom assembly, the bottom assembly including a cooling assembly configured to employ a flexible clamp-type fitting about the vacuum tube body for substantially maintaining thermal and electrical conductivity,
- wherein the cooling assembly is liquid cooled,
- wherein the cooling assembly comprises a copper block heat sink having a cylindrical interior aperture bored to match the outer diameter of the vacuum tube body, a facing side of the copper block heat sink being split and fastened with bolts to produce a snug clamp-on fit of the cooling assembly to the vacuum tube body of the vacuum tube to allow repeated vacuum tube removal upon loosening of the bolts, and
- wherein the top assembly is configured to be releasably fastened to the bottom assembly about the vacuum tube with removable fasteners.
A method for manufacturing a modular magnetron for use in an ultraviolet radiation (UV) curing lamp assembly, comprising the steps of:
- providing a vacuum tube having a vacuum tube body, a top assembly configured to substantially overlay the vacuum tube, and a bottom assembly configured to substantially extend about the vacuum tube, the vacuum tube being positioned to partially protrude from the bottom assembly, the bottom assembly including a cooling assembly comprising a flexible clamp-type fitting, wherein the cooling assembly comprises a copper block heat sink having a cylindrical interior aperture bored to match the outer diameter of the vacuum tube body,
- splitting and fastening a facing side of the copper block heat sink with bolts to produce a snug clamp-on fit of the cooling assembly to the vacuum tube body of the vacuum tube to allow repeated vacuum tube removal upon loosening of the bolts;
- liquid cooling the cooling assembly;
- fitting the flexible clamp-type fitting about the vacuum tube body;
- receiving the vacuum tube in the bottom assembly and the top assembly;
- and
- fastening the top assembly to the bottom assembly about the vacuum tube with releasably removable fasteners.
