Experimental Study on Performance of Flat Finned Tube Water Catcher
摘要
Abstract
A flat finned tube water catcher is designed in this paper,and its condensation heat transfer and water catching performance are tested experimentally under the conditions of simulated heat source initial mass of 50-90 kg,simulated heat source initial temperature of 50-80℃and coolant liquid temperature of 1-7℃.The results show that the change trend of actual instantaneous heat exchange amount in vacuum pre-cooling process can be divided into three stages,which first rises slowly(lasting about 100 s),followed by a sharp increase and rapid decrease,eventually stabilizing after about 1 400 s.The larger the initial mass of the simulated heat source,the higher the initial temperature of the simulated heat source and the lower the temperature of the coolant liquid,the greater the instantaneous heat exchange amount,with a maximum of 78.84 kW.The average water vapor capture rate is 89.77%,which is better than the smooth tube baffle structure under the same working conditions.The temperature of coolant liquid has the greatest influence on the water vapor capture rate.When the temperature rises from 1 to 7℃,the water vapor capture rate decreases from 93.47%to 82.37%.The measured overall heat transfer coefficient of the catcher ranged from 32.28 W/(m²·K)to 55.11 W/(m²·K),primarily affected by the mass of simulated heat source.关键词
