Low-temperature gas flow insertion in printing system dryers

摘要

Systems and methods are provided for inserting low temperature gas into dryers of printing systems. The system comprises a dryer, which includes a heating element and a flow generator. The heating element is within an interior of the dryer and is able to heat a web of printed media as the web travels through the interior. The flow generator is within the interior and is operable to directly project an impinging jet of gas along a width of the web that deflects heated air proximate to the web. The gas is cooler than the heated air.

主权项

1. An apparatus comprising:
a dryer of a printing system; a heating element within an interior of the dryer that is operable to apply radiant heat to a web of printed media as the web travels through the interior; a flow generator within the interior that is operable to directly project an impinging jet of gas along a width of the web that deflects heated air proximate to the web, wherein the gas is cooler that the heated air; a reflector that is positioned between the flow generator and the heating element and is oriented to reflect radiant heat from the heating element away from the flow generator; and
an insulated jacket that surrounds an external surface of the flow generator and receives a volume of gas that insulates the external surface of the flow generator from the heated air.
