STUDY ON HIGH PERFORMANCE HEAT TRANSFER ANDHEAT TRANSPORT WITH LESS ENERGY USING THIN FILM EVAPORATION HEAT TRANSFER PHENOMENA

本研究旨在澄清薄膜蒸发传热现象，并提高蒸发传热性能。在基础研究方面，设计并优化了多层网格曲面和交叉槽曲面这两种新型曲面几何结构。对气泡供给薄液膜表面的蒸发换热性能进行了测量。在应用研究中，我们研究了电子冷却和太阳能集热器。根据实验结果，找出了提高蒸发传热性能的最佳条件。

We studied to clarify thin-film evaporation heat transfer phenomena and to increase evaporation heat transfer performance. In basic research, we devised and optimized the new-type surface geometry of the multilayer-meshed surface and the cross-grooved surface. We measured evaporation heat transfer performance of the surfaces supplied with thin liquid film by bubbles. In application study, we studied the electronics cooling and the solar collector. As the results, we found the optimum conditions to increase the evaporation heat transfer performance.
