蒸发冷却是一种主要用于牵引变流器的冷却技术。蒸发冷却组件内部为自然循环的冷却剂，外部采用通风冷却。组件为铸铝结构，十分坚固，适用于最苛刻的周围条件。至80年代末，正在使用的或已经定货的蒸发冷却组件已超过3300套。它们在大功率GTO变流器上的应用显示了特别的优越性。一个典型的应用实例是德国DB铁路的401型（ICE）动车组的变流器。尽管使用的冷却剂R113属于目前有争议的碳氟化合物，但是蒸发冷却仍将是对环境无危害的可靠技术。
Evaporative cooling is a cooling technique that is used primarily for traction converters. Evaporative cooling components inside the natural circulation of coolant, the external use of ventilation cooling. The components are cast aluminum and are extremely robust for the most demanding ambient conditions. By the end of the 1980s, more than 3,300 evaporative cooling modules were in use or already ordered. Their use in high-power GTO converters shows particular advantages. A typical application example is the converter of the Type 401 (ICE) EMU in the German DB Railway. Despite the fact that the coolant R113 used is currently the most controversial fluorocarbon, evaporative cooling will remain a reliable technology that is environmentally friendly.
