[0065] In an embodiment, referring to Figure 1 and Figure 3 , the tower structure further comprises a plurality of sealing plates 4; each sealing plate 4 is installed on all the second cross beams 31 along the height direction of the base 1 and the vertical beams 21 on the outer sides of the adjacent two tower frames 2 along the circumferential direction of the base 1; the tower-type heat exchange device further comprises a heat energy recycler 5 and a chimney cover 6; the heat energy recycler 5 is arranged in the central space of the tower structure and located at the center of the plurality of heat exchanger units; and the chimney cover 6 is installed at the top of the tower structure and arranged concentrically with the heat energy recycler 5.

[0066] As an example, the tower structure further comprises a plurality of sealing plates 4; a plurality of heat exchanger units generate hot air in the tower structure when working in the tower structure, and the hot air contains heat. In order to reasonably utilize resources, each sealing plate 4 is installed on all the second cross beams 31 in the height direction of the base 1 and the vertical beams 21 outside the adjacent two tower frames 2 in the circumferential direction of the base 1 during installation. In this way, a sealed space can be formed in the entire tower structure, and the hot air generated by the plurality of heat exchanger units can be collected in the central space of the tower structure. The heat energy recovery device 5 is arranged in the central space of the tower structure and located at the center of the plurality of heat exchanger units. The heat energy recovery device 5 can absorb the heat in the hot air generated by the heat exchanger units. Through waste heat recovery technology, the heat generated by the plurality of heat exchanger units when working in the tower structure can be utilized again, such as for power generation, heating or process heating. Therefore, the overall utilization efficiency of energy is improved, the demand for raw energy is reduced, and the cost of energy procurement is reduced. The chimney cover 6 is installed at the top of the tower structure and arranged concentrically with the heat energy recovery device 5. Specifically, the chimney cover 6 comprises a top cover 61 and a chimney 62. The top cover 61 is installed at the top of the tower structure and seals the central space of the tower structure. The chimney 62 is a cylindrical structure and can communicate with the heat energy recovery device 5. When the temperature of the hot air in the central space of the tower structure is higher than the outdoor temperature, there is a pressure difference between the inside and outside of the tower structure. Under the chimney effect of the chimney 62, the hot air is sucked out by the chimney 62 after passing through the heat energy recovery device 5. The hot air passes through the heat energy recovery device 5 during the suction process, and the heat in the hot air is absorbed and utilized by the heat energy recovery device 5. The prerequisite for installing the heat energy recovery device 5 is that the heat generated by the heat exchanger units makes the temperature of the hot air in the central space of the tower structure higher than 60 degrees. When the temperature is lower than 60 degrees, the heat energy recovery device 5 can not be installed.

[0067] In an embodiment, referring to Figure 8 The heat energy recovery device 5 comprises an outlet water tank 51, an inlet water tank 52 and a plurality of connecting water pipes 53.

One end of each connecting water pipe 53 is connected to the outlet water tank 51, and the other end of each connecting water pipe 53 is connected to the inlet water tank 52. The inlet water tank 52 is provided with an air outlet 54, and the air outlet 54 is located at the center of the plurality of connecting water pipes 53.

[0068] As an example, the heat energy recycler 5 comprises an outlet water tank 51, an inlet water tank 52 and a plurality of connecting water pipes 53. The outlet water tank 51 is used to store hot water that absorbs heat, and a water outlet is arranged on the outlet water tank 51 to facilitate people to use the hot water in the outlet water tank 51.

When installed, the outlet water tank 51 and the inlet water tank 52 are arranged at intervals along the height direction of the base 1. Specifically, the outlet water tank 51 is installed on the base 1, the plurality of connecting water pipes 53 are arranged at intervals in a ring shape on the outlet water tank 51, and the inlet water tank 52 is installed on the plurality of connecting water pipes 53. In this way, the cold water in the inlet water tank 52 can flow into the outlet water tank 51 through the plurality of connecting water pipes 53. In the process of flowing, the heat in the hot air generated by the plurality of heat exchanger units is absorbed by the plurality of connecting water pipes 53, so as to heat the cold water flowing through the connecting water pipes 53, thereby improving the overall utilization efficiency of energy, reducing the demand for original energy and reducing the cost of energy procurement. An air outlet 54 is arranged on the inlet water tank 52, and the air outlet 54 is located at the center of the plurality of connecting water pipes 53. In this way, when the temperature of the hot air in the middle space of the tower structure is higher than the outdoor temperature, there is a pressure difference between the inside and outside of the tower structure. Under the chimney effect of the chimney 62, the hot air is sucked out of the chimney 62 through the air outlet 54 of the heat energy recycler 5. In the process of being sucked out, the hot air passes through the heat energy recycler 5, and the heat in the hot air is absorbed and utilized by the heat energy recycler 5.

[0069] In an embodiment, with reference to Figure 1 , Figure 2 and Figure 3 , the tower heat exchange device further comprises a sensor and an air pressure regulator 7. The sensor is arranged in the tower structure and connected to the air pressure regulator 7, and is used to output a pressure signal. The air pressure regulator 7 is arranged at the chimney opening of the chimney cover 6, and is used to adjust the air pressure in the middle space of the tower structure according to the pressure signal.

[0070] As an example, the tower heat exchange device further comprises a sensor and an air pressure regulator 7; during installation, the sensor is arranged in the tower structure and connected with the air pressure regulator 7, so that the pressure in the tower structure can be monitored in real time and a pressure signal is output; the air pressure regulator 7 is arranged at the chimney opening of the chimney cover 6, and can adjust the air pressure in the middle space of the tower structure according to the pressure signal output by the sensor. Normally, the hot air generated by the heat exchanger unit works through the pressure difference generated by the chimney effect, and when the pressure difference between the inside and outside of the tower structure is insufficient due to strong wind interference, the sensor starts the air pressure regulator 7 to adjust the pressure in the tower structure; in this way, the energy-saving effect is more prominent, the chimney effect effectively reduces the power consumption of the air pressure regulator 7, and is more in line with the development concept of energy saving and emission reduction and circular economy. The air pressure regulator 7 adopts a fan structure.

[0071] In an embodiment, referring to Figure 1 and Figure 2 , the tower heat exchange device further comprises a solar charging module 8 and a lighting lamp; the lighting lamp is arranged on the tower structure; the solar charging module 8 is arranged outside the tower structure and connected with the lighting lamp and the air pressure regulator 7.

[0072] As an example, the tower heat exchange device further comprises a solar charging module 8 and a lighting lamp; during installation, the lighting lamp is arranged on the tower structure, which can provide lighting function and provide convenience for installation and disassembly of the heat exchanger unit. The solar charging module 8 is arranged outside the tower structure and connected with the lighting lamp and the air pressure regulator 7; in this way, the solar charging module 8 can be charged by solar energy, and provide power for the lighting lamp and the air pressure regulator 7 during power failure, and assist the heat energy recovery device 5 to maintain a weak working state.
