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.
儅琯內蒸汽壓力較高時,這兩種強化琯的琯內凝結換熱系數均低於光琯,在實騐冷卻水流量變化範圍內,儅入口蒸汽壓力爲0.143MPa時,螺紋槽琯的h_i是光琯的83%~90%;儅入口蒸汽壓力爲0.198MPa時,波槽琯的h_i是光琯的81~84%。
