随着单节功率为4000和6000马力(2944和4416kW)、轴重达25t的干线内燃机车的研制成功,其动力装置和辅助机组的布置条件就越为苛刻,从而产生了关于减小金属用量,其中包括降低冷却装置有色金属的消耗问题。2TЭ10Д(B、M)、T3060、2TЭ116型内燃机车的批量生产机油热交换器的有色金属用量约占冷却装置散热器用量的四分之一。因此,为干线内燃机车研制效率高、金属用量少的机油热交换器是很有实际意义的。
With the success of the development of mainline diesel locomotives with 4,000 and 6,000 horsepower (2944 and 4416 kW) and shaft weights of 25 tons, the layout of the power plant and auxiliary units has become more demanding, resulting in reductions in the amount of metal , Including reducing the consumption of non-ferrous metals in cooling units. 2TЭ10Д (B, M), T3060, 2T1111 diesel locomotive mass production Oil heat exchanger of non-ferrous metal consumption accounts for about a quarter of the cooling device radiator. Therefore, it is very meaningful to develop an oil heat exchanger with high efficiency and less metal consumption for main line diesel locomotives.
