图6显示了本发明所述组件冷却系统的再一个变更实施例，组件包括7个散热器(R1、R2、R3、R4、R5、R6、R7)和6个晶闸管(H1、H2、H3、H4、H5、H6)，还包括电抗器L1、L2。散热器和晶闸管按R1、H1、R2、H2、R3、H3、R4、H4、R5、H5、R6、H6、R7的顺序依次间隔布置。所述组件的冷却系统包括两条冷却液输送支路，第一支路W1冷却液首先流入电抗器L1，从电抗器L1流出后从顺序布置散热器的奇数部分第一只散热器R1流入，按R1、R3、R5、R7顺序串联奇数部分散热器，从奇数部分最后一只散热器R7流出；第二支路W2冷却液首先流入电抗器L2，从电抗器L2流出后从顺序布置散热器的偶数部分最后一只散热器R6流入，按R6、R4、R2顺序串联偶数部分散热器，从偶数部分第一只散热器R2流出。其中，电抗器L1、L2的作用是限制 组件中晶闸管开通过程的电流上升率、承受冲电压，保护晶闸管。
综上所述，采用本发明的上述实施方案后，具有至少以下有益效果：
1)系统的管路结构简单，便于实施；
2)减少了接口数量，降低了发生泄漏的风险，提高了可靠性；
3)组件中每个电力电子器件的热应力基本相同，提高了换流阀组件的利用率；
4)减小了支路管路的流阻，降低了流量。
以上实施例仅为说明本发明的技术思想，不能以此限定本发明的保护范围，凡是按照本发明提出的技术思想，在技术方案基础上所做的任何改动，均落入本发明保护范围之内。
