摘要

Thermoelectric coolers (TECs) were used to cool a low-temperature chemical reactor (LTR).A combined theoretical/experimental study of the heat transfer in LTR with TECs was undertaken.First,two models of a TEC with a LTR junction were developed to evaluate the equilibrium and transient temperatures of the reactor inner wall.Next,two methods were used to determine the parameters of these models.Finally,the relationship between the transient temperatures of the reactor inner wall and cooling times was established.The results show that the calculated results of transient temperatures are in good agreement with the corresponding experimental data.
