The objective of the study is to realize theheat transfer device of wickless two phase fluid loop applying the spontaneous condensate drop movement with the temperature distribution on the heat transfer surface in the vapor-liquid phase change system.The binary mixture of water and ethanol was enclosed in the apparatus as a working fluid. The horizontal arrangement of heat transfer surface was adopted to reduce the effect of gravitational force. As a result, it was shown that the realization of wickless heat pipe was possible by applying the spontaneous condensate drop movement in the water-ethanol binary mixture system with temperature gradient of heat transfer surface.Itwas shown the enough transportation rate of heat.

该研究的目的是实现无芯的两相流体环的热传递装置，该回路施加自发的冷凝水掉落运动，并在蒸气液相变变的热传递表面上的温度分布。采用了传热表面的水平排列，以减少重力的作用。结果，可以通过将自发的冷凝物降落运动在水 - 乙醇二元混合系统中施加，并具有热传递表面的温度梯度，从而实现了无焊热管的实现。
