Abstract
- The saturated reactor is used in the DC converter valve to protect thyristors. A fluid-solid coupling heat dissipation model was established for the saturated reactor in this study, which included water cooling, heat conduction, heat convection and heat radiation. By the means of finite element method, the temperature and flow field distribution were calculated, which indicated that the low thermal conductivity of epoxy resin hinders the heat dissipation of the saturated reactor. To research effects of thermal conductivity on heat dissipation, the heat dissipation performance of saturated reactor with different epoxy resins was numerical simulated by using this model. The results showed that the heat dissipation performance of the saturated reactor can be effectively improved by the rise of the thermal conductivity of epoxy resin, but the marginal benefit of increasing the thermal conductivity of epoxy resin is gradually reduced. Meanwhile, high-thermal conductivity epoxy resin could have the longer service life under the same operation conditions. [ABSTRACT FROM AUTHOR]
