Referring to FIG. 8, after being started, the external power portion 30 draws the air from the air intake vent 121 into the first external air duct A, and then the external power portion 30 exhausts the air in the ventilation room 22 out of the tube tower, to form a flow channel for external circulation heat dissipation on the sealing room 21, and an air flow direction is W in the figure. After being started, the first power portion 31 extracts heat in the sealing room, exhausts the heat into the first internal air duct of the first heat exchanger through the second ventilation opening 216, and then returns the heat to the sealing room 21 through the first ventilation opening 215, to form an air flow and circulate the air flow. In this process, the heat exhausted from the first power portion 31 into the first internal air duct passes through the heat exchange core and the air in the first external air duct for heat dissipation, and then returns to the sealing room 21, to form a flow channel for internal circulation heat dissipation on the sealing room 21, and an air flow direction is N in the figure, to implement both internal circulation heat dissipation and external circulation heat dissipation on the sealing room 21.

After being started, the second power portion 33 extracts the heat in the sealing room, exhausts the heat into the second internal air duct of the second heat exchanger through the second ventilation opening 216, and then returns the heat to the sealing room 21 through the third ventilation opening 217, to form internal circulation heat dissipation. The device is mounted in the support area, and may be in close contact with the third side plate 26, thereby helping remove the heat. Setting of the second heat exchanger further assists heat dissipation of the first heat exchanger, and heat dissipation of a communications device with a relatively large heat emission volume can be more efficient, thereby reducing damage to the device.
