    • In an information processing apparatus with a cooling structure using a heat transport measure such as a heat pipe and a liquid-cooling system, a heat radiation unit has reduced thickness and noise and an improved efficiency. Heat generated by a CPU is transmitted through a heat receiving header and a flexible tube to the heat radiation unit by liquid coolant transported by a pump. The heat radiation unit comprises a propeller, a wall surface in contact with the propeller, and a cooling pipe spirally wound around a propeller shaft in a plane perpendicular to the propeller shaft. Hot coolant is circulated so as to enter the central portion of the cooling pipe and to be discharged from the outer peripheral portion of the pipe. The cooling air from the propeller is made to flow from the central portion of the cooling pipe toward its peripheral portion. The cooling pipe is thermally connected to the wall surface so that the wall surface works as a heat spreader.
    • 在具有使用诸如热管和液冷系统之类的传热措施的冷却结构的信息处理设备中,散热单元具有减小的厚度和噪声并提高效率。 由CPU产生的热量通过由泵输送的液体冷却剂通过热接收头和柔性管传递到散热单元。 散热单元包括螺旋桨,与螺旋桨接触的壁表面,以及在与螺旋桨轴垂直的平面中螺旋地缠绕在传动轴上的冷却管。 热冷却剂循环进入冷却管的中心部分并从管的外周部排出。 来自螺旋桨的冷却空气从冷却管的中心部分向其周边部分流动。 冷却管与壁面热连接,使得壁面作为散热器工作。
