Experimental investigation of the transient behavior of micro heat pipes
Abstract
An experimental investigation was conducted on several small, tapered micro heat pipes specifically designed for use in the thermal control of ceramic chip carriers to verify the operation, measure the performance limits and transient behavior, and determine the accuracy of a previously developed numerical model. The experimental data are compared with the results of a previously developed analytical model to determine the accuracy of the model and verify the predicted trends. The transient numerical model is capable of accurately predicting the maximum transport capacity prior to the onset of dry out, the temperature distribution throughout the longitudinal position, and the temperature difference between axial locations on the heat pipe to within 0.3 C.
