<P>PROBLEM TO BE SOLVED: To provide a cooling tube structure in which a water-cooling type heat dissipation mechanism with improved cooling efficiency and cooling capability can be realized. <P>SOLUTION: The cooling tube structure comprises: an inner tube 12 provided coaxially in an outer tube 11 at a clearance from an inner wall of the straight outer tube 11; and plural spacers 13 (13a-13c) supporting the inner tube 12 in the outer tube 11 and having drift current faces (DF) generating a vortex flow (WP) along an outer periphery of the inner tube 12 to cooling water (Ca1) flowing in the outer tube 11. A flow rate of a cooling water (Ca2) flowing in the inner tube 12 is made faster than a flow rate of the cooling water (Ca1) flowing in the outer tube, and a flow channel 12a of the secondary cooling water (Ca2) for cooling the primary cooling water (Ca1) is formed in the inner tube 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
