核级换热器防冻能力的研究与产品开发

Research and product development of anti-freezing capability of nuclear heat exchangers

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.
