Abstract
The method can include: using a mold, casting an encapsulation onto a workpiece including solidifying the encapsulation around the workpiece in the mold and extracting the encapsulation from the mold, and cooling the extracted encapsulation using a vortex tube.
Claims15
A system for encapsulating a workpiece, the system comprising:
- a casting station configured to cast an encapsulation around a workpiece;
- a cooling station having an enclosure configured to receive the encapsulation and workpiece, the enclosure including a first enclosure and a second enclosure;
- and
- a vortex tube having a pressurized air inlet, a cool air outlet fluidly connected to the pressurized air inlet, and a hot air outlet fluidly connected to the pressurized air inlet, the cool air outlet being fluidly connected to the enclosure,
- wherein the vortex tube includes a first vortex tube and a second vortex tube each having an inwardly facing cone blocking a central area within the hot air outlet, the inwardly facing cone is at a first position relative the hot air outlet when the encapsulation is at a first temperature, the first position causing temperature of air exiting the cool air outlet to be at a higher temperature and at a higher flow rate, and the inwardly facing cone is at a second position relative the hot air outlet when the encapsulation is at a second temperature, the second position causing the temperature of air exiting the cool air outlet to be at a lower temperature and a lower flow rate, the higher temperature being higher than the lower temperature, the higher flow rate being higher than the lower flow rate,
- the cool air outlet of the first vortex tube is fluidly connected to the first enclosure, the inwardly facing cone of the first vortex tube being at said first position;
- the cool air outlet of the second vortex tube is fluidly connected to the second enclosure, the inwardly facing cone of the second vortex tube being at said second position,
- wherein the first enclosure has a larger internal volume than the second enclosure, both the first enclosure and the second enclosure having a volume of less than 40 times a volume of the encapsulation.

- a vortex tube having a pressurized air inlet, a cool air outlet fluidly connected to the pressurized air inlet, and a hot air outlet fluidly connected to the pressurized air inlet, the cool air outlet being fluidly connected to the enclosure;
- wherein the cooling station is configured in a manner for the temperature of air exiting the cool air outlet to be at a higher temperature and at a higher flow rate when the encapsulation is at a first temperature, and to be at a lower temperature and a lower flow rate when the encapsulation is at a second temperature, the higher temperature being higher than the lower temperature, the higher flow rate being higher than the lower flow rate;
- wherein:
- the enclosure is a plurality of enclosures including a first enclosure and a second enclosure;
- the vortex tube is a plurality of vortex tubes including a first vortex tube and a second vortex tube;
- the cool air outlet of the first vortex tube is fluidly connected to the first enclosure and is tuned to said higher temperature and said higher flow rate;
- the cool air outlet of the second vortex tube is fluidly connected to the second enclosure and is tuned to said lower temperature and said lower flow rate;
- and
- wherein the first enclosure has a larger internal volume than the second enclosure, both the first enclosure and the second enclosure having a volume of less than 40 times a volume of the encapsulation.
