An ink jet apparatus includes a head, a circuit substrate, a cover frame, a heat sink, a fan, and a wall section. The cover frame supports the circuit substrate that has a drive circuit that drives the head inside of the cover frame and has a through hole. The heat sink that dissipates heat generated in the circuit substrate is disposed inside of the cover frame and has a part that is in direct or indirect contact with the circuit substrate. The fan generates air flow and is arranged such that the fan and the heat sink face to each other via the through hole. The wall section is disposed inside of the cover frame such that the air flow is not directly blown against the drive circuit and the air flow having changed a direction after blown against the heat sink is not blown against the drive circuit.

In one example, a dehumidifier for an inkjet printer includes a condensing unit and a chiller to circulate coolant through the condensing unit. The condensing unit is made of a thermally conductive material forming elongated exterior condensing surfaces and an interior coolant flow passage extending lengthwise between the condensing surfaces.

An inkjet printer includes solvent vapor generators that direct two flows of solvent vapor on each side of each printhead in the process direction toward media passing the printheads in the printer. The solvent vapor attenuates the evaporation of ink solvent from ink drops on the nozzle plates or from the ink in the nozzles of the printheads. Thus, the ink on the nozzle plates and in the nozzles does not dry out and the operational status of the inkjets is preserved.

A liquid ejecting device includes an ejecting head configured to eject liquid to a medium, a conveyance belt including an adhesive layer to which the medium is bondable, the conveyance belt being configured to convey the medium with the adhesive layer, a heating unit configured to heat the conveyance belt, a pressing unit configured to press the medium against the conveyance belt heated by the heating unit, a channel member configured to define a channel of the liquid to be supplied to the ejecting head, an airflow generation unit configured to generate airflow to be jetted to the conveyance belt past the pressing unit, and a heat exchange mechanism configured to exchange heat between a heat absorption unit configured to absorb heat and a heat dissipation unit configured to emit heat. The heat dissipation unit makes contact with the channel member, and the heat absorption unit is disposed in a course of an airway path through which the airflow moves.

A printing apparatus includes a heat transfer system for transferring heat away from or to a print medium moving in a movement direction through the printing apparatus. The heat transfer system includes a heat transfer member with a rotatable support surface configured for supporting the print medium. The heat transfer member is provided with at least one channel. The support surface is rotatable around an axis in order to move the print medium in the movement direction. A fluid circulation means is configured for supplying a fluid through said at least one channel. The at least one channel is configured such that, in operation, when fluid is supplied through said at least one channel, torque is generated in a fluido-mechanical manner around said axis, contributing to a rotational movement of the support surface of the heat transfer member.
