设计了热柱蒸发端和冷凝端吸液芯的结构,采用犁切-挤压加工方法成形热柱吸液芯,分析热柱吸液芯犁切-挤压成形特征、条件及成形机理。分析表明:犁切-挤压深度对吸液芯表面形貌起决定作用,犁切-挤压深度越大,表面形貌越好;沟槽间距只有在一定的范围内,才能形成优异的表面形貌。实验结果表明:当犁切-挤压深度为0.3mm、环状沟槽间距为0.4mm、径向沟槽夹角为3°时,热柱蒸发端形成较优的强化沸腾结构;当犁切-挤压深度为0.3mm、环状沟槽间距为0.4mm、轴向沟槽间距为π/3mm时,热柱冷凝端形成较优的冷凝强化结构。
The structures of the hot column evaporation end and the condensation end suction wick are designed. The hot column suction wick is formed by the method of plow cutting-extrusion, and the plow-extrusion characteristics, conditions and forming mechanism of the hot column suction wick are analyzed. The analysis shows that the plow-squeezing depth plays a decisive role on the topography of the wick, and the plow-squeeze depth is larger and the surface topography is better. Only when the spacing of the grooves is within a certain range can an excellent surface be formed Topography The experimental results show that when the cutting depth of the plow is 0.3mm, the distance between annular grooves is 0.4mm and the angle between radial grooves is 3 °, the evaporation edge of the hot column forms a better enhanced boiling structure. When the plow cutting - The depth of extrusion is 0.3mm, the spacing of annular groove is 0.4mm, and the axial groove spacing is π / 3mm, the condensation of the hot column will form a better condensation strengthening structure.
