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.
