【摘? 要】針對某核電廠RRI/SEC板式換熱器旁路改造后無法按照傳熱系數(shù)來進行換熱器性能評價的現(xiàn)狀，論文給出了一種使用熱負荷來評價換熱器性能的方法，在曲線上方的試驗數(shù)據(jù)說明換熱器性能合格，可以實現(xiàn)冬季運行時換熱器試驗不需要進行運行模式切換。

【Abstract】The performance evaluation of RRI/SEC plate heat exchanger in a nuclear power plant can not be evaluated according to the heat transfer coefficient after the bypass modification， aiming at this situation， the paper puts forward a method to evaluate the performance of heat exchanger by using heat load， the test data above the curve shows that the performance of heat exchanger is qualified， which can realize the heat exchanger test in winter without switching operation mode.
