Summary

Four types of physical models for the dynamic heat transfer characteristics of heat pipes are discussed, as well as their interrelationships and the physical significance of their parameters, by calculating the transient response of the heat transfer. Using four different heat pipes, the temperature response at each point within the heat pipe and the temperature of the cooling water were measured for a step change in the heat input, and the results were compared with the model predictions. The lumped-parameter model tended to underestimate the time constant of the thermal response, while the homogeneous model tended to overestimation. The predictions of the structural model and the step model were reasonably close to the experimental results.
