蜗状铝合金散热型材模具
本专利技术涉及一种铝合金散热器用型材生产模具,特别是涉及一种蜗状铝合金散热型材模具。
技术介绍
现有作为散热器的铝型材都是在由基板和翼板构成,使用时基板与发热部件接触连接,然后靠翼板散热,现有翼板都是开放式的并排排列,翼板靠与空气直接接触将热量散发到空气中,所以空气流动性对其散发效率至关重要,在没有风时这种结构无法形成较大的对流,所以散热效率较低。这种铝合金型材多是通过挤出工艺来生产,生产挤出成型中空管状产品时,铝合金坯先要进入多个流道到达挤出口,再汇合融为一体由挤出口挤出成型,铝合金坯进入多个流道过程中分离成多路无形提高了阻力,需要更高的挤压压力才能成型,多路铝合金坯汇合时受工艺条件稳定性影响也容易出现褶皱或裂隙,这些仍有待于技术解决。
