<p><P>PROBLEM TO BE SOLVED: To make a sink section of an information processing device thin, silent, and highly efficient in the information processing device including a cooling structure using heat transmitting means. such as a heat pipe and a liquid cooling system. <P>SOLUTION: Heat produced in a CPU 1 is transmitted with the aid of a cooling fluid transported with a pump 5 to a sink section 200 after passage through a heat reception header 4 and a flexible tube 7. The sink section 200 comprises a propeller 9, a wall surface 12 in contact with the propeller 9, and a spiral cooling pipe 8 wound spirally around a rotary shaft 9(b) to provide a surface located perpendicularly to the propeller rotary shaft 9(b). The cooling fluid is circulated such that a high temperature cooling fluid is injected from a central portion of the cooling pipe 8 and is drained from an external peripheral portion. Cooling air from the propeller 9 is adapted to flow toward the peripheral portion from the central portion of the cooling pipe 9. Further, the wall surface 12 is adapted to be a heat spreader by thermally connecting the cooling pipe 8 to the wall surface 12. <P>COPYRIGHT: (C)2004,JPO</p> |
