Considering thermohydrodynamic instabilities in the design of cooling systems has become a trend, which has led to the evolution of thermal management. However, such instabilities, which cause flow perturbations, are difficult to explain by using physical theories. The aim of this study was to use a parameter-based modeling technique, namely the response surface methodology (RSM), to characterize the dynamics of multiloop heat pipes (MLHPs) under various heat loads. The RSM, which is based on statistics, was used to determine the relationship between the design parameters and thermal responses of MLHPs, which are represented using polynomials. Th aim of our RSM modeling was to explore the condensation process in MLHPs. Through this exploration, the optimal heating load condition was determined for MLHPs. In the operation range of 10–110 W, MLHPs exhibited high performance at a charge ratio of 31.1% to 44.2% and poor performance at a charge ratio from 71% to 84%. The RSM can be used to find solutions to avoid the failure of chaotic cooling devices.
