随着动力装置(包括内燃机车柴油机)的机组功率的增加,故在其冷却系统中采用传统的装置已越来越成为问题。也就是说,当现代的内燃机车单节功率为3000～4000马力时,冷却装置的体积要占机器间体积的12～18％,而其重量要占簧上重量的7～9％。制造它要用有色金属2.2～3.1吨,而让它工作时则要消耗柴 With the increase in unit power of power plants, including diesel locomotives, the use of conventional devices in their cooling systems has become increasingly problematic. That is to say, when the power of a modern diesel locomotive is 3,000 to 4,000 horsepower, the volume of the cooling device accounts for 12 to 18% of the volume of the machine and the weight of the cooling device accounts for 7 to 9% of the sprung weight. It uses non-ferrous metals to manufacture 2.2 ~ 3.1 tons, while letting it work will have to consume fuel
