| 研究開始時の研究の概要 |
This work deals with optimization of loop heat pipe heat transfer performance using self-adaptive porous structures as wick. Sufficient pore size for each power leads to smaller pressure drop/better performance. Pore size variation range and efficiency of performance optimization will be clarified.

| 研究実績の概要 |
We designed, evaluated performance of the dual-evaporator loop heat pipe (LHP). PTFE membranes were used as wick. Operating characteristics of the LHP in various orientations was clarified. Effect of vapor/liquid distribution in reservoirs on the performance was discussed. One article was published on a high impact journal.
However, the pore size variation range of PTFE wick was limited due to its structure. Melamine foam, a novel material with open foam structure and superhydrophilicity which has not been used so far, was proposed. Pore size of melamine foam was controlled from 215 micron to 18 micron with very small changes in porosity and permeability. The melamine prototype exhibited better performance than the PTFE LHP.
