摘要
随着内燃机车功率的不断提高,要求机车冷却系统散逸的热量越来越大,散热器数量的增加,使得冷却系统流程数也相应增大,导致机车冷却系统通水阻力和水系统压力都大幅度提高。在常规冷却系统设计方法的基础上,研究提出了多流程散热器。简要介绍了其结构特点、性能试验、传热性能指标对比及装车运用等情况。该多流程冷却系统具有冷却效率高、结构简单、水泵消耗的辅助功率小及冷却系统部件工作可靠性高等优点。
As the diesel locomotive power increases, there is the need for locomotive cooling system to dissipate more amount of heat. Increasing number of radiators results in increasing number of flow pathes of cooling system, and so the water flow resistance and water pressure in locomotive cooling system raise remarkably. Based on common design method for cooling system, this paper presents a multiple flow pathes radiator. The structural characteristics, performance test, comparison of heat transfer performance indexes and operations on locomotive, et al., were discussed. The multiple flow pathes cooling system has many advantages such as high cooling efficiency, simple structure, low power consumption by the cooling water pump and high reliability of cooling system parts.
