Then, the vortex coil 304 connected to the outer wall of the cooling outer cylinder 301 near the bottom is pre-buried into the soil at the installation location until the bottom of the conical mounting seat 313 is fixed. After the mounting flange 314 is fitted with the soil surface at the installation location (optionally, a layer of concrete structure can be laid on the pre-buried soil ground, and some bolts for connection and fixing can be pre-buried, so that the mounting flange 314 can be fixedly connected to the laid concrete ground through the pre-buried bolts to strengthen the stability of the connection and fixation between the cooling element 3 and the pre-buried soil ground), the cooling element 3 is connected and fixed to the installation ground through external fasteners, so that the heat energy during operation can be transferred to the ground in the later stage, the cooling efficiency of the entire system can be increased, and the service life of the tower 1 can be improved; After the above installation process is completed, the installation cylinder 401 is lifted and inserted into the top of the cooling outer cylinder 301 by a crane, so that the positioning groove 410 opened at the bottom of the installation cylinder 401 is inserted and engaged with the circular clamping ring 315, thereby covering and sealing the top of the heat absorption cavity 303 formed by the outer wall of the heat absorption inner cylinder 302 and the inner wall of the cooling outer cylinder 301 through the bottom of the installation cylinder 401 (the inside of the heat absorption inner cylinder 302 is coated with a material that accelerates heat absorption).

Finally, when passing through the interior of the vortex coil 304, it is transferred to the pre-buried soil, thereby completing the water cooling process in the entire process, avoiding the impact of excessive temperature on the operation of the internal equipment of the system during operation, and also avoiding the impact of excessive temperature on the internal working environment of the system; In rainy conditions, the falling rainwater flows into the fan-shaped water storage tank 508 through the water diversion trough 510 and the drainage trough 511 (after the tower 1 is hoisted, plugged, installed and fixed, the several fan-shaped plates 505 and the several fan-shaped inclined plates 507 fit together to form a complete disc and inclined cone, thereby activating a certain protective joint. After fitting together, the fan-shaped plates 505 and the fan-shaped inclined plates 507 that fit together are waterproof sealed by waterproof glue), and finally falls into the annular water storage tank set on the conical mounting seat 313 through several water pipes 509 (the annular water storage tank is an annular water tank structure, and its bottom is connected to a flow pipe connected to the inside of the liquid storage tank 311), and finally flows into the inside of the liquid storage tank 311, so that the collected rainwater can be used to perform water cooling and heat dissipation on the entire system in the later stage.
