Using ploughing-extrusion method, a cross-connected finned micro-grooves structure was formed on the surface of copper strips with thickness of 0.4 mm. The structure was fabricated by making ‘V’-grooves in copper strips and perpendicular ‘V’-grooves on the opposite side that intersect the first set of grooves. Micro pores appear at the intersection of these cross-connected grooves, and micro fins...
In this paper, a rectangle- & V-channels interconnected boiling enhancement structure was manufactured by ploughing-extrusion and multi-tooth planing processes based on copper strips with 0.5mm in thickness. The rectangle channels are 0.5mm in width, 0.4mm in depth and 1mm in pitch. While in the opposite surface, the V-channels are 0.6mm in depth, 40° in groove angle and 0.48mm in pitch. These...
