Patent attributes
An inkjet head includes a flow passage unit having an ink flow passage formed therein, in which ink flows, and an actuator unit secured to the flow passage unit. The actuator unit is configured to apply a discharge energy to the ink within the ink flow passage. The inkjet head also includes a driver IC configured to supply a drive signal to the actuator unit, a plurality of plates extending from the flow passage unit, and a cover member secured to the plurality of plates. The cover member, the plurality of plates, and the flow passage unit define a closed space, and the driver IC is disposed within the closed space. Moreover, the driver IC opposes at least a portion of an inside surface of one of the plurality of plates and is thermally coupled to the one of the plurality of plates, and an outside surface of the one of the plurality plates has a heat radiation property which is greater than a heat radiation property of the inside surface of the one of plurality of plates.
