| Abstract: | A study was made of the heat transfer characteristics of the spiral plate heat exchangers with non-circular pin fins through experiments.The heat-transfer analogy naphthalene sublimation technology was used to measure the convective heat exchange coefficients of the circular pin fins,the column surfaces of two kinds of oval-shaped pin fins,and the channel bottom of the columns when Re= 4 000~ 7 000,the heat transfer law of the spiral channels of the oval-shaped pin fins was derived,and the comprehensive performance was compared. |
