摘要:
An image forming apparatus includes an air-conditioning section to control at least one of temperature and humidity of air, a first passage to guide the air sent off by the air-conditioning section to a temperature-controlled portion in the image forming apparatus, an air-intake section to take in the air from outside of the image forming apparatus, and a second passage to guide the air taken in by the air-intake section to the temperature-controlled portion.

A liquid-cooling-type cooling device includes a circulatory path for coolant that cools a temperature rise portion; a heat absorbing unit that absorbs a heat from the temperature rise portion by the coolant; a heat radiating unit that radiate the heat from the coolant; a pump that circulates the coolant; and a plurality of liquid-contacting metal portions that comes into contact with the coolant, each of the liquid-contacting metal portions being made of a metal material. At least one of the liquid-contacting metal portions is grounded.

A cooling device using a liquid coolant, including a heat receiving part separatably contactable to a target to be cooled detachably installable in an image forming apparatus, a heat releasing part to release heat from the liquid coolant, a circulation channel through which the liquid coolant is circulated between the heat receiving part and the heat releasing part, and a pump operatively connected to the circulation channel to convey the liquid coolant through the circulation channel. The circulation channel has a flexible part and a metal part continuous with the flexible part.

A cooling device includes a heat receiving unit arranged to contact with a cooling target to receive heat of the cooling target; a heat radiating unit configured to radiate heat of coolant; a tank configured to store therein the coolant; a circulating path configured to circulate the coolant through the heat receiving unit, the heat radiating unit, and the tank; a pump configured to transfer the coolant in the circulating path; and a liquid transfer detecting unit configured to detect liquid transfer of the coolant. The liquid transfer detecting unit includes a detector arranged above a liquid level of the coolant stored in the tank at a position where the coolant having flowed into the tank is hit when the coolant is transferred. The detector is arranged so as to be visible from the outside of the tank.

摘要:
A cooling device including at least two cooling members to cool a recording medium passing thereover, a coolant circulation unit to circulate a coolant, and tubing that connects the coolant circulation unit to the cooling members and through which the coolant circulates. Each of the cooling members includes a heat-absorbing surface that directly contacts the recording medium or indirectly contacts the recording medium via a thermal transmission member, an internal channel provided within each of the cooling members through which the coolant circulates, and a channel inlet and outlet formed at downstream and upstream ends of each of the cooling members in a direction of conveyance of the recording medium, respectively. One of an interval and a thermal insulator is provided between the cooling members.
