Abstract
A cooling efficiency is increased. An inkjet head is provided with a head main body for jetting ink, a cooling pipe which has corrosion resistance to the ink, and through which the ink for cooling a drive circuit passes, and a cooling member which has higher thermal conductivity than that of the cooling pipe, in which at least a part of the cooling pipe is embedded, and which has recessed parts in at least a part of a portion surrounding the cooling pipe.
Claims13
A liquid jet head comprising:
- a jet section configured to jet liquid;
- a drive circuit operable to drive the jet section to jet the liquid;
- a cooling pipe which has corrosion resistance to the liquid, wherein the cooling pipe is configured to pass a cooling medium through the cooling pipe;
- and
- a cooling member which has higher thermal conductivity than thermal conductivity of the cooling pipe, wherein the cooling pipe is insert-molded in the cooling member, and the cooling member is in direct contact with the drive circuit in a vicinity of the cooling pipe, and further wherein the cooling member has at least one recessed part formed to at least partially surround the cooling pipe.
