Single and two phase microchannel cooling is studied by models and experiments. For single phase cooling three models are discussed: a molecular dynamics model, a Monte Carlo method and a continuum model (CFD), Also microchannel cooling experiments with water and air as coolant are discussed. The experiments and the simulations show good agreement. A pulsating heat pipe is considered as an example of two phase cooling. A one--dimensional model and experiments are compared. The trends are predicted well by the model. However, there is a large difference in absolute values between the model and the experiments. Therefore the model needs some modifications for the three-dimensional phenomena that occur in the experiments.

Pulsating heat pipes: a challenge and still unsolved problem in heat pipe science

Modern micro electronics thermal management is facing considerable challenges in the wake of miniaturizing of components leading to higher demands on net heat flux dissipation. This paper highlights the salient features of Pulsating Heat Pipes (PHPs), a novel research topic in the heat pipe science, having potential applications in thermal management of micro/power electronics. This apparently simple cooling device, is considerably intriguing for theoretical and experimental investigations alike. Fundamental operating principle, flow characteristics, design parameters and limitations are discussed in detail. The unresolved open questions which are subject to further investigations are also outlined.
