抄録

The single-phase forced-oscillating-flow heat-pipes utilize the extraordinarily enhanced diffusion in oscillating flows inside channels. Dream pipes and COSMOS heat pipes are typical examples of such heat pipes and they have great potential for micro heat pipes and flexible heat pipes. On the other hand, they need external supply of power and so the optimization of system parameters is of great importance to reduce the power consumption. In the present paper, the optimum conditions achieving the highest effective thermal conductivity and/or the highest operating coefficient are analyzed for a given amplitude of the oscillating flow. The parameters in the optimization are the thermophysical properties of the operating liquid, the channel size and the frequency of oscillating flow. It is found that, under the optimized condition, COSMOS heat pipes excel dream pipes in thermal performance and ρc_p together with Pr is important to determine the optimum operating liquid.
