The air heat exchange device according to claim 5, characterized in that: A buffer groove (16) is provided at the connection between the shell (1) and the anti-seismic ring (6), and elastic blocks (160) are provided inside the buffer groove (16) and at the upper and lower ends of the anti-seismic ring (6).

7. The air heat exchange device according to claim 1, characterized in that: A temperature sensor is arranged inside the water outlet pipe (13), a circulation pipe (17) is arranged between the water outlet pipe (13) and the water inlet pipe (12), and a switching valve is arranged on the circulation pipe (17).

8. The heat exchange method of an air heat exchange device according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1, connecting the air inlet pipe (15) to an external heat source, and connecting the water inlet pipe (12) to an external water source; S2, the external heat source passes through the first coil (20), the second coil (21) and the vertical pipe (22) in sequence, and finally passes through the exhaust pipe (14) and is discharged from the shell (1) for collection; S3, the water source entering the shell (1) exchanges heat with the heat source of the first coil (20), the second coil (21) and the vertical pipe (22), and the temperature of the water increases, and the water is finally discharged from the shell (1) through the outlet pipe (13) to be used by downstream equipment; S4. During the operation of the device, the length of the branch pipe (220) on the extension pipe (221) is adjusted using the adjustment component (3) according to the demand for water temperature of the downstream equipment, so as to adjust the heat exchange amount between the first coil (20), 21-the second coil (21) and the vertical pipe (22) and the external water source.
