| Abstract: | In this paper,a miniature helical evaporator has been designed,fabricated,and tested.The characteristics of boiling heat transfer and pressure drop is studied experimentally.Based on the experimental results,a correlation for the frictional factor was obtained as Reynolds number varies from 1460 to 10000.The experimental results indicated that the miniature evaporator can transfer over 300W heat energy. |
