    When entranced steam pressure is 0.103MPa, the corrugated tube's condensation heat transfer coefficient h_i increase of 10%~32% compared with that of bare tube; the spiral fluted tube's condensation heat transfer coefficient h_i increase of 11%~40% compared with that of bare tube; on the condition of high steam pressure, these two enhanced tubes' condensation heat transfer coefficient h_i is lower than that of bare tube, in the range of cooling water flow, when the entranced steam pressure is 0.143MPa, the h_i of spiral fluted tube is about 83%~90% of the bare tube's h_i;when the entranced steam pressure is 0.198MPa the corrugated tube's h_i is about 81%~84% of the bare tube's h_i. The result of the helix spring insert's enhance condensation heat transfer experimental investigation shows: when the entranced steam pressure is 0.143MPa, the h_i of tube within the helix spring insert is about 15%~25% higher than that of bare tube, but the total pressure drop is about 8.1 times of the bare tube.
    当管内蒸汽压力较高时,这两种强化管的管内凝结换热系数均低于光管,在实验冷却水流量变化范围内,当入口蒸汽压力为0.143MPa时,螺纹槽管的h_i是光管的83%~90%;当入口蒸汽压力为0.198MPa时,波槽管的h_i是光管的81~84%。
