Experimental study on the heat transfer coefficient and flow resistance of the tube when the air is obliquely scouring the tube bundle is carried out. The experimental results are also analyzed. The correlation between heat transfer and flow resistance under the experimental conditions is given. The design of the tube bundle provides the data basis.The experimental results show that the tube bundle with oblique flushing has a better overall heat transfer effect than the horizontal scouring.
