%X 目前，蓄热式换热器可以大幅提高设备的热交换效率以及温度效率，同时可以满足特殊换热环境下的需求。但对于换热温度、加热时间以及压降确定的情况下，传统方法无法完成蓄热式换热器的设计。本文以压降和加热时间为双重收敛标准，提出了一种新的周期性换热蓄热式换热器设计计算方法。克服了蓄热式换热器在周期性换热过程中不同流量和通流时间等约束条件下的设计难点，解决了其双向换热长度、加热时间、压降和温度分布等计算问题。本文提出的方法简化了蓄热式换热器的设计过程，具有很强的工程应用价值。<br />
At present, regenerative heat exchangers can greatly increase heat transfer efficiency and temperature efficiency, and can meet the requirements of special heat exchange conditions. But under the condition that heat transfer temperature, heating time and pressure drop have been determined, the traditional method cannot complete the design of regenerative heat exchanger. This paper proposed a new design method of periodic regenerative heat exchanger which takes the pressure drop and the heating time as the double convergence standards. This method overcomes the design difficulties of the regenerative heat exchanger in the periodic heat transfer process, such as different flow rates and flow time constraints. And the calculation problems of the bidirectional heat transfer length, heating time, pressure drop and temperature distribution are solved. The method proposed in this paper simplifies the design process of the regenerative heat exchanger and has a strong engineering application value.
