An ion-drag pump is utilized to enhance the heat transport capacity of micro heat pipes. An analytical model is developed to estimate the maximum heat transport capacity as a function of the applied electric field. The model demonstrates that four times increase in heat transport capacity is made possible through application of an electric field. The model predictions are shown to match experimental data well. Given the potential for augmentation of heat transport capability, a transient analytical model was developed to permit variation of the electric field with applied thermal load. A proportional-integral-derivative controller was used to simulate active temperature control. The feasibility of achieving the active temperature control was demonstrated experimentally.
