Ink jet apparatus has two piezoelectric actuators (106, 108) arranged back-to- back on parallel thermal management surfaces (50a, 50b) of a water-cooled chassis (100). The chassis is formed by the bringing together of two concave plastic moulded parts (102, 104), having high thermal conductivity. A common nozzle (112) plate attached to the two actuators helps to ensure accurate nozzle alignment.
L'invention concerne un appareil à jet d'encre comprenant deux actionneurs piézo-électriques (106, 108) agencés dos à dos sur des surfaces (50a, 50b) gestion thermique parallèles d'un châssis (100) refroidi par de l'eau. Ledit châssis est formé par rapprochement de deux parties concaves (102, 104) moulées en plastique à conductivité thermique élevée. Une buse commune (112) plate fixée aux deux actionneurs permet d'aligner ladite buse avec précision.
