The traditional design method of Jacket heat exchanger has heavy workload and low efficiency. Based on Simulink module library,the design system of Jacket heat exchanger is developed to improve the design efficiency. This method can not only simulate the dynamic characteristics of Jacket heat exchanger under the intermittent heat transfer but also analyze the effect of the design parameters. The example analysis shows that the dynamic characteristic curves of intermittent heat transfer can be simulated so as to provide the basis to improve the efficiency of the heat exchanger,and the modification of parameters of the method is easy and visual and it is of good efficiency and engineering application value, thus to provide a new idea for the analysis of intermittent heat transfer of Jacket heat exchanger.
