Ink-jet print head and method thereof |
摘要 |
An ink-jet print head preventing thermal accumulation on a nozzle plate includes a substrate, a channel formed in the substrate to supply ink, a nozzle plate connected to the substrate and including a nozzle corresponding to the channel, a heat element formed in the nozzle plate to surround the nozzle, a thermal conduction layer formed on an upper side of the heat element formed between the thermal conduction layer and the heat element, and a thermal shunt spaced-apart from the heat element by a predetermined distance not to overlap the heat element in a direction parallel to the nozzle plate and connecting the thermal conduction layer to the substrate. Redundant heat generated from the heat element is not accumulated on a membrane of the nozzle plate but is rapidly absorbed into an inorganic thermal conduction layer formed in the membrane and is transferred to the bulk silicon substrate through a metallic thermal bridge, such as the thermal shunt.
