散热器的发展趋势是钢制散热器逐步取代铸铁散热器。但是在近期内,铸铁散热器仍将被大量采用。我们与辽宁省黑山县铸造厂承担了改造大60型散热器的研制任务,已取得积极成果。我们认为大60的外形几何尺寸是可取的,经过多年的安装使用没有什么问题,可以在外形尺寸不变的条件下就其金属耗量大、传热效率较低、外形不够美观、承受压力低这些主要缺点进行改造。对原大60进行解剖,发现绝大部分产品的主体壁厚是不均 The development trend of radiators is that steel radiators gradually replace cast iron radiators. However, in the near future, cast iron radiators will still be used in large quantities. Together with the foundry of Heishan County, Liaoning Province, we undertook the task of reconstructing the Big 60 radiator and achieved positive results. We believe that the 60’s geometry is desirable. After many years of installation and use, there is no problem. It can have large metal consumption, low heat transfer efficiency, unattractive appearance and low pressure under the same dimensions. These major shortcomings are transformed. Anatomy of the original large 60, found that the body wall thickness of most products is uneven
