发明名称 Ink flow heat exchanger for inkjet printhead
摘要 An ink conduit for an inkjet printhead is disclosed which increases the velocity of ink flowing across the back surface of a substrate and into ink ejection chambers. The increased velocity of ink across the back surface of the substrate results in greater removal of heat from the substrate. This increased ink velocity is achieved by providing narrow ink conduit openings proximate to the back surface of the substrate. To avoid air bubbles becoming trapped in the relatively narrow ink conduit, one or more pockets are formed to allow the accumulation of bubbles, so that the bubbles do not affect the ink flow through the ink conduit and into the ink ejection chambers.
