Abstract(summary):

The intensified boiling and condensation wick structures of heat column were designed and manufactured by ploughing-extrusion (P-E) machining method. The forming process and mechanism were analyzed. The results show that the P-E depth plays a decisive role in forming of wick structure. The larger the P-E depth is, the better the surface characteristics are. Only when the groove spacing is in a certain range, superior surface structure can be formed in the wick. The better enhancement boiling structure forms at P-E depth of 0.3 mm, ringed groove spacing of 0.4 mm, and interior angle of radial groove of 3 degrees; the better enhancement condensation structure forms at P-E depth of 0.3 mm, ringed groove spacing of 0.4 mm, and axial grooves spacing of pi/3 mm.
