When the temperature reaches a certain temperature, the air pressure reaches a predetermined value, which will press down the heat-insulating sealing floating plate. The water in the cold water tank flows toward the heat exchange pipeline under the pressure of the heat-insulating sealing floating plate. The water flows in the heat exchange pipeline and finally flows into the water storage cavity. At the same time, the water flowing in the heat exchange pipeline exchanges heat with the hot air on the top of the cabinet cavity and cools down the hot air in the cabinet cavity. This not only improves the use stability and safety of the devices in the cabinet cavity, but also eliminates the need to use additional electrical heat dissipation equipment for heat dissipation, thereby reducing the cost required for heat dissipation.

The heat exchange pipeline 3 is arranged at the top of the cabinet cavity 11 and is located below the heat transfer layer 111. The heat exchange pipeline 3 is distributed in an "S" structure, and one end of the heat exchange pipeline 3 is connected to the bottom side of the cold water tank 13, and the other end is connected to the liquid surface above the water storage cavity 14.

[0036] In this embodiment, when the temperature in the cabinet 1 is high, the hot air is concentrated on the top of the cabinet cavity 11 and heats the air in the air cavity 12 through the heat transfer layer 111. The air in the air cavity 12 increases in temperature, so the air pressure increases. When the temperature reaches a certain temperature, the air pressure reaches a predetermined value, which will press down the heat-insulating sealing floating plate 4. The water in the cold water tank 13 flows toward the heat exchange pipeline 3 under the pressure of the heat-insulating sealing floating plate 4. The water flows in the heat exchange pipeline 3 and finally flows into the water storage cavity 14. At the same time, the water flowing in the heat exchange pipeline 3 exchanges heat with the hot air at the top of the cabinet cavity 11 and cools down the hot air in the cabinet cavity 11. This not only improves the use stability and safety of the devices in the cabinet cavity 11, but also eliminates the need to use additional electrical heat dissipation equipment for heat dissipation, thereby reducing the cost required for heat dissipation.

[0040] Furthermore, as a preferred embodiment, in order to improve the heating effect of the heat transfer layer 111 toward the air cavity 12, the heat transfer layer 111 is a copper plate layer.

[0041] Furthermore, as a preferred embodiment, the bottom of the heat transfer layer 111 has a plurality of long grooves 1111 , which increase the contact area between the bottom of the heat transfer layer 111 and the hot air in the cabinet cavity 11 , and further improve the heating effect of the heat transfer layer 111 toward the air cavity 12 .

[0042] Furthermore, as a preferred embodiment, the cross-section of the long groove 1111 is a “V”-shaped structure, which further increases the contact area between the bottom of the heat transfer layer 111 and the hot air in the cabinet cavity 11 .

[0043] Furthermore, as a preferred embodiment, the bottom of the water storage chamber 14 is connected to the bottom of the cold water tank 13 via a connecting hole 191 , and a blocking member 5 is provided in the connecting hole 191 , and the blocking member 5 can be operated to open or block the connecting hole 191 .

[0045] In this embodiment, during heat dissipation operation, as the water storage amount in the water storage chamber 14 increases, the water pressure on the sealing plate 52 increases. When the water pressure on the sealing plate 52 is greater than the elastic force of the spring 51, the sealing plate 52 will be pushed away from the sealing surface, so that the water in the water storage chamber 14 flows into the cold water tank 13 through the connecting hole 191, and the cold water tank 13 is replenished with water, thereby realizing the recycling of water.
