The invention belongs to the technical field of transformer cooling, and discloses a ship propeller and a matched phase-shifting transformer cooling water system.The ship propeller comprises a gearbox, a power shaft is installed in the middle of the gearbox, a bearing box is installed at the rear end of the power shaft, and a spiral propelling device is installed at the output end of the bearing box; a power assembly located on the outer side face of the power shaft is installed between the gearbox and the bearing box, and a phase-shifting transformer body is arranged on one side of the gearbox. A traditional closed type water cooling structure is abandoned, an open type structure is adopted, when a ship enters water, external water flow is directly sucked for heat dissipation, cooling liquid circularly flowing in a pipeline is not used for heat dissipation, a fan does not need to be arranged for heat dissipation of the cooling liquid, heat is taken away through a large amount of water flow in a river, and heat dissipation efficiency is improved. The water flow sucked by the cooling system every time is low in temperature, the pressure of the cooling system is reduced, and then the cooling efficiency is improved.
本发明属于变压器冷却技术领域,且公开了一种船舶推进器及其配套移相变压器冷却水系统,包括齿轮箱,所述齿轮箱的中部安装有动力轴,所述动力轴的后端安装有轴承箱,所述轴承箱的输出端安装有螺旋推进装置,所述齿轮箱和轴承箱之间安装有位于动力轴外侧面的动力组件,所述齿轮箱的一侧设有移相变压器本体。本发明通过摒弃传统的封闭式水冷结构,转而采用开放式的结构,即通过船只下水时,直接吸取外部的水流来进行散热,而非使用管道内循环流动的冷却液进行散热,也无需设置风扇进行冷却液的散热,通过河流中大量的水流来带走热量,使得冷却系统每次吸取的水流均为温度较低的水流,降低冷却系统压力,进而提高冷却效率。
