E-shaped combined liquid cooling heat dissipation structure

The invention belongs to the technical field of aviation electrical, and provides an E-shaped combined liquid cooling heat dissipation structure for a switched reluctance motor controller in an aviation high-voltage direct-current switched reluctance high-power starting/power generation system. Comprising N parallel cold plates and a long cold plate which is connected with the N parallel cold plates and is vertical to the N parallel cold plates, one side, far away from the long cold plate, of each of the N cold plates is also connected with a liquid inlet pipe; cooling liquid flows into the N cold plates in parallel through the liquid inlet pipe to cool the N cold plates. And cooling the long cold plate after flowing out of the N cold plates, and converging and flowing out. 本发明属于航空电气技术领域，针对航空高压直流开关磁阻大功率起动/发电系统中的开关磁阻电机控制器提出了一种"E型"组合式液冷散热结构。包括：N块平行冷板和与N块平行冷板相连且垂直的长冷板；所述N块冷板远离长冷板一侧还连接有进液管；冷却液经进液管平行流入N块冷板，对N块冷板进行冷却；从N块冷板流出后对长冷板进行冷却并汇集流出。
