| 2 | 25x2.5 | 2.75 | 0.3 | 300 | 1.1 | 24.8 | 2.2 | 1.9 | 1000,Tp=1.0 |
| 3 | 19x2 | 2.8 | 0.3 | 300 | 0.9 | 18.8 | 1.65 | 2.1 | 125,Tp=0.8 |
| 4 | 19x2 | ~2.93 | 0.3 | 300 | 1.1 | 18.8 | 1.65 | 1110,Tp=0.9 |
The present invention in an experiment, using 9 ± 0.1 DEG C of refrigerant R134a saturation temperature, 12 DEG C of inlet water temperature, in-pipe flow speed
Variation range is 1-3m/s.
The present invention is that rectangular channel is increased on fin with the advantages of prior art, so that the liquid film between two fins can
Can mutually circulate by rectangular channel, it can thus make liquid film damaged, so as to increase the heat exchange efficiency of heat exchanger tube.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
