The lower side of the casing 1 is connected to an air inlet check valve 12 connected to the air outlet of the air pump 2, and the air inlet check valve 12 is connected to the rubber layer. The air inlet check valve 12 is provided with a lock structure located on the casing 1 to fix the air inlet check valve 12. The casing 1 is injected with an immersed heat-conducting liquid, and one end of the heat pipe 31 extends into the immersed heat-conducting liquid. The casing 1 is fixed with an exhaust head 101 located above the immersed heat-conducting liquid by bolts, and the exhaust head 101 is connected to a one-way conduction channel connected to the casing 1 and the rubber layer;

[0037] When in use, the air intake check valve 12 is fixed to the casing 1 through the locking structure, and then the casing 1 is turned over so that the air intake check valve 12 is facing upward. At this time, the air intake check valve 12 is in a conducting state, and the immersion heat-conducting liquid is injected into the casing 1 through the air intake check valve 12. After the injection is completed, the air pump 2 is connected to the air intake check valve 12 through a pipeline, and then the casing 1 is turned over so that the air intake check valve 12 is placed downward, and then the casing 1 is fixed to the communication tower.
