Study on Kilowatt-Level Cladding Power Stripper Using Spiral Flow Channel Water-Cooling Technology
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%.
