Experimental investigation was conducted on the convective heat transfer coefficient in a vertical flat-plate evaporator of a loop-type heat pipe, of which the working fluid was distilled water. The evaporator was made of copper and the heating area dimensions were 190×114 ㎟. The condenser was an air-cooled fin-tube heat exchanger. Heat flux was varied from 5 to 139 kW/㎡, while the evaporator was maintained below 100°C. Three different evaporator surface conditions were compared: bare surface, screen mesh covered, and hybrid wick covered. The wick-covered surfaces exhibited distinctly higher heat transfer to bare surface, for heat fluxes higher than 88 kW/㎡. The bare surface showed moderately higher heat transfer coefficients for heat fluxes up to 69 kW/㎡, but decreased thereafter and eventually resulted in overheating at 106 kW/㎡. The surface with a hybrid wick exhibited a heat transfer coefficient of 10,300 W/㎡·K at a heat flux of 139 kW/㎡.
