基于螺旋流道水冷技术提出一种新的千瓦级包层功率剥离器结构,并对其散热性能进行了研究。首先,将该结构与传统水冷式包层功率剥离器及热沉吸热式包层功率剥离器对比,验证了其实用性与优越性。其次,通过研究螺旋流道参量,发现热沉初始温度对剥离器的散热性能无明显影响,大直径的螺旋冷却管道及合适的冷却水初始温度将有利于散热。最后,实验发现在优化条件下该剥离器能有效剥离4200W以下的包层功率。在剥离1000W包层功率时,该剥离器温度峰值为300.49K、温度谷值为284.29K、温差为16.2K;同等功率下,相比于上述传统剥离器,其温度峰值最多降低了15.1%,温度谷值最多降低了10.3%,温差最多缩小了73.4%。

In this paper, a new structure of kilowatt-level cladding power stripper is proposed based on spiral flow channel water-cooling technology, and its heat dissipation performance is studied. First, the structure is compared with the traditional water-cooled cladding power stripper and the heat sink endothermic cladding power stripper to verify its practicability and superiority. Second, by studying the parameters of the spiral flow channel, it is found that the initial temperature of the heat sink has no significant effect on the heat dissipation performance of the stripper. The large diameter spiral cooling pipe and the appropriate initial temperature of the cooling water will help heat dissipation. Finally, it is experimentally found that the stripper can effectively strip the cladding power below 4200W under optimized conditions. When stripping 1000 W cladding power, the peak temperature of the striper is 300.49K, the temperature valley is 284.29K, and the temperature difference is 16.2K. Under the same power, compared with the above-mentioned traditional stripper, the peak temperature is reduced by up to 15.1%, the temperature valley is reduced by up to 10.3%, and the temperature difference is reduced by up to 73.4%.
