Abstract
In some examples, a carriage for a printing system includes a printhead, a conduit to carry a cooling airflow to the printhead, a return chamber to receive a heated exhaust airflow produced from heating of the cooling airflow by the printhead, and a seal between the printhead and the return chamber to prevent the heated airflow from flowing to a location below the printhead.
Claims15
A carriage for a printing system, comprising:
- a printhead;
- a conduit to carry a cooling airflow to the printhead;
- a return chamber to receive a heated exhaust airflow produced from heating of the cooling airflow by the printhead;
- and
- a seal between the printhead and the return chamber to prevent the heated airflow from flowing to a location below the printhead.
2 more elements
A printing system comprising:
- a carriage that is moveable with respect to a print platform of the printing system;
- a printhead carried by the carriage to deliver an agent to a target on the print platform;
- and
- an active cooling subsystem attached to the carriage and comprising:
- an airflow generator;
- a tubular conduit connected to the airflow generator and in contact with the printhead, the tubular conduit to transport a cooling airflow produced by the airflow generator to the printhead;
- and
- an exhaust opening through which a heated exhaust airflow is to flow away from the print platform.
5 more elements
A method of forming a carriage for a printing system, comprising:
- mounting a printhead to a mounting structure of the carriage;
- attaching an active cooling subsystem to the carriage, the active cooling subsystem comprising an airflow generator and a tubular conduit connected to the airflow generator;
- and
- arranging the active cooling subsystem adjacent the printhead to provide a cooling airflow generated by the airflow generator through the tubular conduit to the printhead.
