Abstract
A liquid discharge head is provided which comprises a head body, a casing and a thermal insulator. The head body comprises a surface having one or more holes configured to discharge liquids therethrough. The casing, disposed on the head body, comprises a heat generator configured to generate heat and a heat sink configured to dissipate the heat. The thermal insulator is between the heat sink and the head body.
Claims10
A liquid discharge head, comprising:
- a head body comprising a surface having one or more holes configured to discharge liquids therethrough;
- a casing, disposed on the head body, comprising:
- a heat generator configured to generate heat;
- and
- a heat sink configured to dissipate the heat;
- and
- a thermal insulator between the heat sink and the head body.
4 more elements
A liquid discharge head, comprising:
- a head body comprising:
- a first surface comprising discharge holes, configured to discharge liquids therethrough;
- a second surface opposed to the first surface, comprising:
- a first opening defining an inlet for a liquid;
- and
- a second opening defining an outlet for undischarged liquid that has not discharged at the discharge holes;
- a supply flow channel between the first opening and the discharge holes, allowing the liquid to flow from the first opening to the discharge holes;
- and
- a return flow channel between the second opening and the discharge holes, allowing undischarged liquid to flow from the discharge holes to the second opening;
- a first wall member on the head body, comprising a first material;
- and
- a second wall member on the first wall member, comprising a second material that is higher in thermal conductivity than the first material.
