  • Patent number: 9864334
    Abstract: A recording-material cooling device includes a first cooling member, a second cooling member, an approach-and-separation member, and a positioning member. The first cooling member is disposed at a first face side of a recording material to absorb heat of the recording material. The second cooling member is disposed at a second face side of the recording material to absorb heat of the recording material. The approach-and-separation member brings the first cooling member and the second cooling member close to and away from each other. The positioning member positions the first cooling member and the second cooling member relatively brought close to each other by the approach-and-separation member.

  • Patent number: 9483018
    Abstract: A recording-material cooling device includes a first belt, a first cooling unit, and a second cooling unit. The first belt is disposed at a first face side of a recording material. The first cooling unit has a first heat absorbing surface to contact the first belt to absorb heat of the recording material. The second cooling unit has a second heat absorbing surface to directly or indirectly contact the recording material to absorb heat of the recording material. The second cooling unit is disposed at a second face side of the recording material. The first and second cooling units are offset from each other in a transport direction of the recording material. Each of the first and second surfaces has a shape in which an inner area protrudes beyond opposed ends in the transport direction. The first and second surfaces overlap each other in a direction crossing the transport direction.

  • Patent number: 9354601
    Abstract: A liquid type cooling device, which is incorporated in an image forming apparatus, includes a heat receiving part including a heat receiving unit to transport heat from a cooling target to a coolant and a heat releasing part including a heat releasing unit, a cooling fan, and an air flowing space. The heat releasing unit has a coolant flowing path and an air flowing path through which air passes and conducts heat exchange with the coolant. The air flowing space has an air inlet port and an air outlet port. When the air flowing path has an upstream region and a downstream region along a coolant flowing direction of the coolant flowing path, air at high temperature flows into the upstream region of the air flowing path. Alternatively, the heat releasing unit may have a coolant inlet port, a coolant outlet port, and the air flowing path.
