It might be a possible solution for the increasing energy consumption for thermal management because of its high effectiveness. Previous research on the ECE has investigated several possible methods to build a model based on ECE and feasibilities to increase the efficiency of the model. But there has been no study on all the factors that may affect the performance of the device. Thus, in this paper, we designed a cooling device based on ECE and simulated it by using the control variates method showing that a high efficiency can be reached through stated model.展开更多

It is an extension of the thermal control. This discussion introduces the concept and development of thermal management, presents the aspects of thermal management and further extends its application to subsystems of the space station.展开更多
