Apparatus for controlled freezing of melted solid ink in a solid ink printer
An apparatus controls dissipation of heat from melted ink within a component storing melted ink within a solid ink imaging device. The apparatus includes a housing, a passage within the housing that is configured to store melted ink, and a temperature control connector mechanically coupled to the housing and passage, the temperature control connector being configured to mitigate void formation in melted ink as the melted ink cools in the passage.
1. A component for holding melted ink in a solid ink printing system comprising:
a housing;
a passage within the housing that is configured to store melted ink; and
a thermal conductor mounted to the exterior of the housing and mechanically coupled to the housing and passage, the thermal conductor being configured to mitigate void formation in melted ink as the melted ink cools in the passage.
2. The component of claim 1 further comprising:
a heat sink mechanically connected to the thermal conductor to dissipate heat conducted by the thermal conductor from the melted ink within the passage.
3. The component of claim 1 wherein the thermal conductor is also mechanically connected to a heat source to enable heat to flow to the melted ink within the passage as the melted ink cools within the passage.
4. A component for holding melted ink in a solid ink printing system comprising:
a housing;
a passage within the housing that is configured to store melted ink; and
a thermal conductor extending through an exterior of the housing and mechanically coupled to the housing and passage, the thermal conductor being configured to mitigate void formation in melted ink as the melted ink cools in the passage.
5. The component of claim 4 further comprising:
a heat sink mechanically connected to the thermal conductor to dissipate heat conducted by the thermal conductor from the melted ink within the passage.
6. The component of claim 4 wherein the thermal conductor is also mechanically connected to a heat source to enable heat to flow to the melted ink within the passage as the melted ink cools within the passage.
7. A print head for ejecting melted ink onto an image receiving substrate comprising:
a housing;
a reservoir within the housing that is configured to store melted ink for ejection from the print head; and
a thermal control element that is mounted to an exterior of the housing at a position to thermally couple the thermal control element to the melted ink within a portion of the reservoir to enable the thermal control element to dissipate heat from the melted ink within the portion of the reservoir.
8. The print head of claim 7 further comprising:
a heat sink mechanically connected to the thermal control element to dissipate heat conducted by the thermal control element from the melted ink within the portion of the reservoir.
9. The print head of claim 7 further comprising:
a heat conductor mechanically connected to a heat source to supply heat to the melted ink within a passage in the print head as the melted ink cools within the passage.
10. The print head of claim 7 further comprising:
a taper within a portion of a passage in the print head to control heat dissipation from melted ink within the passage.
11. A print head for ejecting melted ink onto an image receiving substrate comprising:
a housing;
a reservoir within the housing that is configured to store melted ink for ejection from the print head; and
a thermal control element that is mounted to extend through an exterior of the housing to a position proximate the reservoir to thermally couple the thermal control element to the melted ink stored within the reservoir to control solidification of the melted ink within the reservoir.
12. The print head of claim 11 wherein the thermal control element is mounted to extend through the exterior of the housing to a position within the reservoir.
13. The print head of claim 11 further comprising:
a heat sink mechanically connected to the thermal control element to dissipate heat conducted by the thermal control element from the melted ink within the portion of the reservoir.
14. The print head of claim 11 further comprising:
a heat conductor mechanically connected to a heat source to supply heat to the melted ink within a passage in the print head as the melted ink cools within the passage.
15. The print head of claim 11 further comprising:
a taper within a portion of a passage in the print head to control heat dissipation from melted ink within the passage.
