Title (EN) FLUIDIC EJECTION DEVICES WITH ENCLOSED CROSS-CHANNELS
(FR) DISPOSITIFS D'ÉJECTION FLUIDIQUE À CANAUX TRANSVERSAUX ENSERRÉS
Abstract:
(EN) In one example in accordance with the present disclosure, a fluidic ejection device is described. The device includes a fluidic ejection die embedded in a moldable material. The die includes an array of nozzles. Each nozzle includes an ejection chamber and an opening. A fluid actuator is disposed within the ejection chamber. The fluidic ejection die also includes an array of passages, formed in a substrate, to deliver fluid to and from the ejection chamber. The fluidic ejection die also includes an array of enclosed cross-channels. Each enclosed cross-channel of the array of enclosed cross-channels is fluidly connected to a respective plurality of passages of the array of passages. The device also includes the moldable material which includes supply slots to deliver fluid to and from the fluidic ejection die. A carrier substrate of the device supports the fluidic ejection die and moldable material.
(FR) Selon un exemple, la présente invention concerne un dispositif d'éjection fluidique. Le dispositif comprend une matrice d'éjection fluidique incorporée dans un matériau pouvant être moulé. La matrice comprend un réseau de buses. Chaque buse comprend une chambre d'éjection et une ouverture. Un actionneur fluidique est disposé à l'intérieur de la chambre d'éjection. La matrice d'éjection fluidique comprend également un réseau de passages, formés dans un substrat, pour distribuer un fluide vers et depuis la chambre d'éjection. La matrice d'éjection fluidique comprend également un réseau de canaux transversaux enserrés. Chaque canal transversal enserré du réseau de canaux transversaux enserrés est en communication fluidique avec une pluralité respective de passages du réseau de passages. Le dispositif comprend également le matériau pouvant être moulé qui comprend des fentes d'alimentation pour distribuer un fluide vers et à partir de la matrice d'éjection fluidique. Un substrat de support du dispositif supporte la matrice d'éjection fluidique et le matériau pouvant être moulé.
