摘要

摘要: 為了解決方管鋁型材冷卻不均的問題,利用有限元分析軟件Fluent,對方管鋁型材噴水冷卻的溫度場進行了三維瞬態數值模擬,分析了方管鋁型材特征點的溫度場變化規律,研究了擠出成形速度、噴嘴縱向間距及噴嘴橫向間距對方管鋁型材冷卻溫度場的影響.結果表明:擠出成形速度和噴嘴縱向間距對方管鋁型材縱向溫度場影響明顯,而噴嘴橫向間距對溫度場的影響主要表現在橫向上.采用最大的擠出成形速度、最小的噴嘴縱向間距和80mm的噴嘴橫向間距可以得到較均勻的冷卻溫度場.

Abstract: In order to solve the issue of uneven cooling of square tube aluminum profiles,three-dimensional transient numerical simulation for the temperature field of a square tube aluminum profile in spray cooling was carried out by the finite element analysis software Fluent.The change in temperature field at characteristic points in the square tube aluminum profile was analyzed.The influence of extrusion velocity,nozzle vertical separation distance and nozzle horizontal separation distance on the temperature field was researched.The results show that extrusion velocity and nozzle vertical separation distance have a great influence on the temperature field in the vertical direction;and nozzle horizontal separation distance has a great influence on the temperature field in the horizontal direction.With the maximum extrusion speed,minimum nozzle vertical separation distance and a nozzle horizontal separation distance of 80 mm,the temperature field of spray cooling can be more uniform.
