一、概述由于电力机车受到重量、体积的严格限制、对机车用功率器件,特别是对与其相匹配的风冷散热器的要求比地面装置苛刻得多,为解决好这个问题,我们先后花了十余年时间,在理论分析的基础上,经过大量的试验验证,终于成功地设计出了一种重量轻、体积小、热阻流阻均小、成本低的新型风冷散热器,这种新型散热器采用肋片分段叉排的结构,用钢模纯铝重力浇铸、便于制造,目前已开始批量地应 I. Overview As the electric locomotive subject to the weight and size of the strict restrictions on the locomotive power devices, especially with their matching air-cooled radiator requirements than the ground much harsh, in order to solve this problem, we have spent More than ten years, on the basis of theoretical analysis, after a lot of experiments and verification, finally successfully designed a light weight, small size, small thermal resistance flow resistance, low cost of the new air-cooled radiator, this The new radiator using ribs segmented fork rows of structures, with steel mold gravity casting of aluminum, easy to manufacture, has now begun volume should be
