As shown in Fig. 1-2 3, a kind of heat exchanger tube, as shown in Figs. 1-3, including supervisor 11, fin 2 and end pipe 12, the master
Pipe 11 and end pipe 12 are made of aluminium, and the fin 2 is also made of aluminium, and the fin 2 is set as multiple, and along the master
Evenly spaced distribution on the length direction of pipe 11；In this present embodiment, the supervisor 11 and end pipe 12 are disposed as one, and
It is arranged for U-shaped structure, since wherein one end of supervisor 11 is closed, the end pipe 12 is then connected to one end of supervisor's opening
On, and the length of supervisor 11 is more than the length of end pipe 12；In other embodiment, the end pipe 12 may be alternatively provided as two, point
It is not connected on the left and right ends of supervisor 11, the supervisor is set as two straight tubes, and the end pipe is set as U-shaped structure；Specifically
