对９种不同几何尺寸的冲击孔板及其换热靶板，在冷流压力损失控制在１０％以下时，测量其换热的平均努氏数，并依据结果分析冲击换热的影响和影响程度，最后采用多元线性回归法，将结果数据整理成换热的准则关系式。实验结果表明：（１）冲击换热的平均努氏数Ｎｕｄ随冲击孔的雷诺数Ｒｅｄ的增加呈上升趋势，（２）冲击换热的平均努氏数Ｎｕｄ在冲击间距Ｚｎ＝０．８ｍｍ～４．８ｍｍ内，随Ｘｎ／ｄ的增加呈下降趋势，（３）冲击间距Ｚｎ＝０．８ｍｍ～４．８ｍｍ内，冲击换热随冲击间距与冲击孔孔径之比Ｚｎ／ｄ增加而微弱上升，（４）在实验范围内冲击换热的平均努氏数可用下式表示：Ｎｕｄ＝０．２８１（Ｚｎ／ｄ）０．０７１（Ｘｎ／ｄ）－１．２９Ｒｅ０．７６ｄ，式中１５００≤Ｒｅｄ≤１００００，６．２５≤Ｘｎ／ｄ≤８．３３，０．５３≤Ｚｎ／ｄ≤３．００。
Nine kinds of impact orifice plates with different geometries and their heat transfer target plates were tested for the average Knoop number of the heat exchange when the pressure loss of the cold flow was under 10%, and the influence and impact of the impact heat transfer were analyzed based on the results Degree, the final use of multiple linear regression method, the results of the data into heat transfer criteria for the relationship. The experimental results show that: (1) The average Nudge number Nud of impact heat transfer increases with the increase of the Reynolds number Red of impact hole. (2) The average Nudge number Nud of impact heat transfer is about 0.8 ~ 4.8mm, it decreases with the increase of Xn / d. (3) Within the impact distance of Zn = 0.8mm ~ 4.8mm, the impact heat transfer increases slightly with the increase of Zn / d ratio between the impact space and the diameter of impact hole , (4) The average Knoop number of the impact heat transfer in the experimental range can be expressed as follows: Nud = 0.281 (Zn / d) 0.071 (Xn / d) -1.29Re0.76d, where 1500≤ Red≤10000, 6.25≤Xn / d≤8.33, 0.53≤Zn / d≤3.00.
