摘要:
A thermal ink jet printer having enhanced heat removal capability and method of assembling the printer. The thermal inkjet printer includes a thermal inkjet print bead adapted to hold an ink body therein. A heating element is adapted to be in fluid communication with the ink body for generating heat to heat the ink body. A vapor bubble forms in the ink body to eject an ink drop when the heating element causes the ink body to reach a predetermined temperature. Presence of the vapor bubble forces on ink drop out the printer to form an image on a recording medium. A conductive heat removal structure is in thermal communication with the heating element and is also in fluid communication with the ink body. Heat generated by the heating element is transferred from the heating element and into the heat removal structure. The heat removal structure then surrenders the heat to the ink body, which functions as an “infinite” heat sink. In this manner, the heat removal structure provides enhanced heat removal of heat generated by the heating element.
