Abstract: An ink jetting apparatus includes a nozzle module, a driving module, and a membrane. The nozzle module includes an ink chamber for reserving ink, and a nozzle hole for permitting ink in the ink chamber to be jetted therethrough. The driving module includes a working fluid chamber charged with working fluid, a heater disposed in the working fluid chamber, and a plurality of fins fixed to the heater, which are heated by the heater. By pressure from a bubble produced during the heating of the working fluid chamber by the heater, the membrane is curved into the ink chamber, and ink in the ink chamber is jetted through the nozzle hole. Since the bubble is divided by a plurality of fins on the heater, the bubbles disappear rapidly when the heater stops heating. Accordingly, the high-speed operation of the ink jetting apparatus becomes possible, and the ink jetting apparatus is more stably driven.
