<p><P>PROBLEM TO BE SOLVED: To provide a blade server equipped with a cooling structure on which a high performance CPU is mounted. <P>SOLUTION: A groove is formed in a direction almost in parallel with a tube axial direction on the internal surface of a tube, and the cross-section of a fin column is exposed on the groove side face so that drainage performance of condensed operating fluid staying between fins can be increased. In installing a steam condensing tube, the groove is arranged at the lower side in the vertical direction of the center line of the tube axial direction of the steam condensing tube, and a steam condensing tube packed with wicks whose wire spacings are smaller than the fin spacings of the fin column is used for the inside of the groove. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
