[0026] Two sets of storage chambers 2 are opened on the inner side of the support shell 1. One set of storage chambers 2 is the input and the other set of storage chambers 2 is the output. One side of the storage chamber 2 is connected to the connecting pipe 3. One end of the connecting pipe 3 is connected to the external structure through the connecting bolt 4 to facilitate the transmission of synthetic ammonia that needs to be cooled. The input end transmits synthetic ammonia to the inside of the storage chamber 2, the storage chamber 2 transmits synthetic ammonia to the inside of the U-shaped pipe 6, the U-shaped pipe 6 transmits synthetic ammonia to the inside of the output storage chamber 2, and the cooled synthetic ammonia is discharged through the output connecting pipe 3.

[0027] The storage tank 7 is fixed to the inner anti-corrosion layer 8, which is composed of anti-corrosion material to extend the service life of the storage tank 7. The anti-corrosion layer 8 is fixed to the guide plate 23, and the isolation plate 9 is fixed to several guide plates 23 on both sides to ensure the stability of the guide plates 23. Several guide plates 23 form a guide channel, in which the refrigerant moves. During the movement, it absorbs the heat inside the U-shaped tube 6, thereby improving the heat exchange efficiency of the synthetic ammonia.

[0028] One end of the assembly pipe 10 is bolted to a compressor 11. One side of the compressor 11 is connected to a water distribution chamber 13 via a pipe. A support frame 12 is installed on the outside of the water distribution chamber 13. A water guide chamber 16 is installed on the inside of the support frame 12. Several condenser pipes 14 are installed between the water distribution chamber 13 and the water guide chamber 16. Several heat dissipation plates 15 are installed on the outside of the several condenser pipes 14. A guide pipe 17 is installed on one side of the water guide chamber 16. A solenoid valve 18 is installed inside the guide pipe 17. The solenoid valve 18 is connected to an expansion valve 19 through the guide pipe 17.

[0029] One end of the assembly pipe 10 is connected to the compressor 11 by bolts. One side of the compressor 11 is connected to the water distribution chamber 13 by a pipe. The compressor 11 draws water from the storage tank 7 and transfers the water to the inside of the pipe. The pipe transfers the coolant to the inside of the water distribution chamber 13.

The cooled coolant is transferred to the inside of the guide chamber 16 and then to the inside of the guide pipe 17. The guide pipe 17 transfers the coolant to the inside of the solenoid valve 18. The solenoid valve 18 controls the coolant transfer speed and then transfers the coolant from the guide pipe 17 to the inside of the expansion valve 19. The expansion valve 19 throttles and reduces the pressure of the coolant, causing the coolant temperature to drop. The guide pipe 17 then transfers the coolant to the inside of the storage tank 7, where the internal guiding structure facilitates heat exchange.

[0030] Working principle: Compressor 11 draws water from storage tank 7 and transfers it to the pipeline. The pipeline then transfers coolant to water distribution chamber 13, which in turn transfers it to condenser coil 14. Condenser coil 14 guides the coolant movement and is fixed to several heat dissipation plates 15 on its outer side. Cooling fan 21 moves air forward to dissipate heat from condenser coil 14. The cooled coolant is then transferred to water guide chamber 16, which in turn transfers it to guide pipe 17. Guide pipe 17 then transfers the coolant to solenoid valve 18, which controls the coolant transfer speed. The coolant is transferred to the expansion valve 19, which throttles and reduces the pressure, causing the coolant temperature to drop. The guide pipe 17 transfers the coolant to the storage tank 7. The internal guiding structure of the storage tank 7 facilitates heat exchange. One set of storage chambers 2 is the input, and the other set is the output. One side of the storage chamber 2 is connected to the connecting pipe 3. One end of the connecting pipe 3 is connected to the external structure through the connecting bolt 4, which facilitates the transfer of the synthetic ammonia that needs to be cooled. The input end transfers the synthetic ammonia to the storage chamber 2, the storage chamber 2 transfers the synthetic ammonia to the U-shaped pipe 6, and the U-shaped pipe 6 transfers the synthetic ammonia to the output storage chamber 2. The cooled synthetic ammonia is then discharged through the output connecting pipe 3.
