One end of the bottom of the inner wall of the exhaust warehouse 12 away from the communicating pipe 19 is fixedly connected with a collecting pipe 28, and one end of the collecting pipe 28 is fixedly connected with the top of the liquid storage warehouse 17.

[0046] In operation, the liquid storage bin 17 is arranged on the top of the inner wall of the ventilation body 1, the semiconductor refrigeration plate 16 is started at one end of the top of the liquid storage bin 17, and a plurality of refrigeration pipes 18 are arranged at the refrigeration end of the semiconductor refrigeration plate 16, so that the cooling liquid (the cooling liquid is mixed by water and alcohol, and the freezing point is -20℃) in the liquid storage bin 17 is continuously cooled by the refrigeration pipes 18. The liquid discharge pipe 27 is arranged at one end of the bottom of the inner wall of the liquid storage bin 17, so that the cooling liquid enters the annular pipe 22 along the liquid discharge pipe 27. The middle of the inner wall of the refrigeration bin 2 is provided with the heat dissipation fins 20, and the outer wall of the heat dissipation fins 20 is provided with the heat conduction blocks 21 on both sides. One end of the heat conduction blocks 21 is inside the annular pipe 22, so that when the cooling liquid enters the annular pipe 22, the surface temperature of the heat dissipation fins 20 is reduced by the cooling liquid passing through the heat conduction blocks 21, so that when the air discharged from the ventilation pipe 3 enters the refrigeration bin 2, the air passes through the heat dissipation fins 20, the temperature of the air is further reduced, the temperature difference between the exhaust bin 12 and the refrigeration bin 2 is further increased, so that the thermosyphon phenomenon is more obvious, and the flow rate of the air in the ventilation pipe 3 is effectively increased, and the air exhaust efficiency of the air inlet shell 4 is improved.

[0047] The water pump 26 is arranged at one end of the outer wall of the annular pipe 22 away from the liquid discharge pipe 27, so that the cooling liquid circulating in the annular pipe 22 is pumped into the liquid inlet pipe 25 arranged at the output end of the annular pipe 22 by the water pump 26. The partition plate 23 is arranged at one end of the bottom of the inner wall of the liquid storage bin 17, and one side of the outer wall of the partition plate 23 is connected with the outer wall of the liquid inlet pipe 25, so that the cooling liquid circulating is flowed into one side of the partition plate 23 along the liquid inlet pipe 25. Since the partition plate 23 is arranged at the side close to the refrigeration pipe 18, and the space in the liquid storage bin 17 is small, the discharged cooling liquid can quickly contact with the refrigeration pipe 18, and the cooling liquid re-cooled is discharged through the liquid outlet 24 arranged at one end of the outer wall of the partition plate 23 away from the liquid inlet pipe 25, so that the cooling cycle of the refrigeration bin 2 is completed, and the discharged cooling air enters the exhaust bin 12 through the communication pipe 19, and contacts with the heat conduction pipe 14, so that water vapor is generated on the surface of the heat conduction pipe 14. Since the heat conduction pipe 14 has a certain inclination angle, and the collection pipe 28 is arranged at one end of the bottom of the inner wall of the exhaust bin 12 away from the communication pipe 19, so that part of the distillate water not evaporated is dropped along the heat conduction pipe 14 into the exhaust bin 12, and is flowed into the collection pipe 28 along the inner wall of the exhaust bin 12, so that the distillate water is flowed into the liquid storage bin 17 along the collection pipe 28, so that the problem that the temperature of the ventilation pipe 3 is increased when the air in the underground building is extracted by the thermosyphon phenomenon in the conventional underground building energy-saving ventilation device, the temperature difference between the exhaust bin 12 and the ventilation pipe 3 is small, the ventilation efficiency is affected, the temperature difference between the exhaust bin 12 and the ventilation pipe 3 is increased, so that the thermosyphon phenomenon is obvious, and the flow rate of the air in the ventilation pipe 3 is effectively increased, and the air exhaust efficiency is improved.

[0048] The middle part of the ventilation pipe 3 is provided with a shunt bin 29, and the bottom of the inner wall of the shunt bin 29 is provided with a groove 30, one side of the outer wall of the shunt bin 29 is fixedly connected with a waste liquid pipe 31, and the inner wall of the waste liquid pipe 31 is threadedly connected with a blocking piece 32.

[0049] In work, when the outside temperature is high, the air in the ventilation pipe 3 is easy to be heated in the process of going to the refrigeration bin 2, so that the heated air leaves condensate water on the surface of the cooling fin 20 when the heated air contacts the cooling fin 20. When the condensate water falls from the surface of the cooling fin 20, the condensate water enters the shunt bin 29 along the ventilation pipe 3, and the condensate water is collected by the groove 30 arranged at the bottom of the inner wall of the shunt bin 29, so that the pipe is prevented from being damaged by the condensate water. When it is necessary to clean the condensate water stored in the shunt bin 29, the blocking piece 32 arranged in the waste liquid pipe 31 is removed, so that the condensate water is discharged along the waste liquid pipe 31.

By installing the ventilation main body 1 on the roof, and installing one end of the ventilation pipe 3 in the refrigeration bin 2 set on one end of the inner wall of the ventilation main body 1, by setting the exhaust bin 12 on the top of the ventilation main body 1, and setting the heat conducting pipe 14 on one side of the inner wall of the exhaust bin 12, by starting the semiconductor refrigeration plate 16, using the liquid cooling heat conducting bin 15 set on the heating surface to transfer heat to the heat conducting pipe 14, so that the exhaust bin 12 is continuously heated, at this time, the air in the exhaust bin 12 and the air in the ventilation pipe 3 produce temperature difference. Using the thermosyphon phenomenon, the air in the ventilation pipe 3 enters the exhaust bin 12 continuously, and in the process, using a plurality of filter plates 7 set in the filter bin 6 to filter the air in the underground building, so that the air enters the exhaust bin 12 along the ventilation pipe 3, and is discharged through the exhaust pipe 13 set on the top of the exhaust bin 12, further solving the problem that the traditional underground building energy-saving ventilation device is more complex in structure, leading to more cumbersome daily maintenance.
