[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The power distribution distributed DTU terminal device in this embodiment realizes rapid heat dissipation of the device through the cooperation of air channels and cooling fans, while having little impact on the structure.

[0021] like Figure 1 - Figure 4 As shown, the power distribution distributed DTU terminal device includes an outer shell 1 and an inner shell 2, the inner shell 2 is arranged in the outer shell 1, the DTU terminal is arranged in the inner shell 2, the outer shell 1 plays a role of protection and installation, an air channel is arranged between the side wall of the inner shell 2 and the inner wall of the outer shell 1, and a cabinet door 3 is arranged on the front side of the outer shell 1 to facilitate maintenance and installation of the DTU terminal. Inlet holes 31 and exhaust holes 32 are arranged at the edges of both sides of the cabinet door 3, and the air inlet holes 31 and the exhaust holes 32 are arranged in the up and down direction, wherein the air inlet holes 31, the air channel and the exhaust holes 32 form a U-shaped An air circulation channel is provided in the outer shell 1, and a heat dissipation fan 4 is provided in the outer shell 1. The heat dissipation fan 4 is provided corresponding to the exhaust hole 32. In actual use, when the heat dissipation fan 4 is running, fresh air enters through the air inlet hole 31, and then passes through the air channel. When passing through the air channel, the heat accumulated between the outer shell 1 and the inner shell 2 is taken away. The air carries the heat and is finally discharged through the exhaust hole 32, thereby realizing air circulation and achieving a good heat dissipation effect. At the same time, it has little impact on the entire DTU terminal equipment, and a good heat dissipation effect can be achieved without adding too much structure.

[0022] Specifically, Figure 4 As shown, the air passage includes a first channel 5, a second channel 6 and a third channel 7, wherein the first channel 5 is formed between the right side wall of the inner shell 2 and the right side wall of the outer shell 1, the second channel 6 is formed between the rear side wall of the inner shell 2 and the rear side wall of the outer shell 1, and the third channel 7 is formed between the left side wall of the inner shell 2 and the left side wall of the outer shell 1. After the air enters through the air inlet 31, it circulates through the first channel 5, the second channel 6 and the third channel 7 in sequence, and is discharged through the exhaust hole 32. Since the air inlet hole 31 and the exhaust hole 32 are both arranged in multiple numbers up and down, the airflow circulation can be realized quickly.
