Fluid manifold and methods of making the same

摘要

An ink manifold for use with a heater chip in an inkjet printhead, including a first planar surface and a second opposite planar surface, a plurality of ink channels located on the first planar surface of the ink manifold for supplying ink to the heater chip, and a plurality of ink ports located on the second opposite planar surface of the ink manifold, each of the plurality of ink ports being in liquid communication with a respective one of the plurality of ink channels, each of the plurality of ink channels having a bottom wall defined by bottom wall portions that rise from each ink port within the ink channel to a maximum height at an angle of at least 12 degrees.

1. An inkjet printhead, comprising:
a heater chip; an ink manifold coupled with the heater chip and comprising:
a first surface comprising a plurality of ink channels in fluid communication with the heater chip;a second surface that is opposite the first surface and comprising a plurality of ink ports in fluid communication with the respective plurality of ink channels, wherein two or more ink ports are in fluid communication with at least one ink channel;each of the plurality of ink channels having a wall defined by wall portions that incline from each ink port within the ink channel to a height at an acute angle with respect to the first surface of the ink manifold.
