叙述了大功率晶闸管直接浸入氟利昂冷却的结构原理,TF113氟利昂的性能和各种测量数据.介绍了能替代钼片和钙片的结构铜材料,列举了用结构铜制成而不用陶瓷外壳、可直接浸入氟利昂内冷却、热效率高的全焊接晶闸管管芯结构.得出了利用氟利昂冷却可缩小晶闸管组件体积和减轻其重量的结论. Describes the structural principle of high-power thyristor direct immersion Freon cooling, the performance of TF113 Freon and various measurement data.A structural copper material that can replace the molybdenum sheet and calcium sheet is introduced, the structure copper is used instead of the ceramic shell, Directly immersed in the Freon-cooled, thermally-efficient all-welded thyristor die structure, and concluded that the use of freon cooling can reduce the volume of the thyristor assembly and reduce its weight.
