核级换热器防冻能力的研究与产品开发

摘要

针对北方核电站配套暖通设备用换热器在严寒天气下易冻伤的问题,通过对换热器排水能力的分析,提出结构优化方案.在满足抗震和热工性能要求的前提下,实现换热器在非能动状态下内部水份的自然排空.%To solve the easy frost-cracking problem of nuclear power plant HVAC heat exchangers in severe cold weather,proposes a structure optimization scheme based on the analysis of drainage capacity.To meet the requirements of anti-seismic and thermal performance,realizes the natural emptying of inner water in the passive state.
