目前,我国各型内燃机车上运用的都是扁管串平片式散热器。这种散热器结构比较落后,由于它在设计、制造和工艺上的不足,导致传热系数低。这不仅影响了机车柴油机的功率发挥,而且给内燃机车的效率、轮周功率、成本等经济技术指标带来一定影响。本文试对东风型机车扁管串平片式散热器谈一些看法。 (一)对扁管串平片式散热器存在问题的分析我厂在十多年修车实践中,每当炎夏季节,常出现机车油、水温度偏高,尤其是近年来油、水温度超高的现象普遍出现,日益显示了东风型内燃机车冷却能力的不足。南方一些 At present, all types of diesel locomotives in our country are flat tube type flat type radiators. This radiator structure is relatively backward, due to its design, manufacturing and technology deficiencies, resulting in low heat transfer coefficient. This not only affects the power of locomotive diesel engine to play, but also to the efficiency of diesel locomotives, power and cost of the week and other economic and technical indicators have a certain impact. This paper tries to Dongfeng locomotive flat tube string flat radiator discuss some views. (A) of flat tube string flat radiator problems analysis I plant repair practice in more than a decade, whenever the summer season, locomotive oil, water temperature is high, especially in recent years, oil and water temperature Ultra-high phenomenon is widespread, increasingly shows the lack of cooling capacity of Dongfeng diesel locomotive.
