Patent ID: 8515303

Claim:
A liquid-cooling type cooling device which cools a temperature rising part of an image forming apparatus by forming a circulating route of a liquid cooling medium, comprising: a heat receiving section which causes the liquid cooling medium to absorb heat of the temperature rising part; a radiator which causes the heat of the liquid cooling medium to release; and a pump which circulates the liquid cooling medium, wherein the heat receiving section includes a heat receiving main body including a flowing route of the liquid cooling medium, a contacting surface for contacting the temperature rising part, and a heat receiving main body covering part which covers outer surfaces other than the contacting surface of the heat receiving main body; and the heat receiving main body covering part includes a material whose heat conductivity is lower than the heat conductivity of the heat receiving main body, wherein the flowing route penetrates the heat receiving main body that has a solid body other than the flowing route, the solid body encircles and contacts the flowing route, and the flowing route within the heat receiving main body is a continuous uniform flow route.
