All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-8 , the present invention provides a technical solution: a highly efficient and energy-saving evaporative condenser structure, including a bottom plate 1, above which there is a heat exchange box 2 fixed thereto through a plurality of support legs 3.

A heat exchange pipe 6 located inside the heat exchange box 2 is connected between the liquid outlet pipe 5 and the intake pipe 4.

[0030] The spraying mechanism 7 is arranged on the bottom surface of the heat exchange box 2 and is used for spraying water mist onto the heat exchange tubes 6. The spraying mechanism 7 includes a water pipe 71 fixed to the bottom surface of the heat exchange box 2 through a plurality of fixing rods 76, a water pump 72 installed on the bottom surface of the heat exchange box 2, two water outlet pipes 74 rotatably connected to the top surface of the water pipe 71 and communicating with its inner cavity, two sprockets 77 respectively coaxially fixed on the circumferential outer walls of the two water outlet pipes 74 and located below the heat exchange box 2, and a motor 79 installed on the top surface of the water pipe 71 and used to drive the two sprockets 77 to rotate. The water outlet end of the water pump 72 is tightly sleeved with a water inlet pipe 73 communicating with the inner cavity of the water pipe 71. The water outlet pipes 74 penetrate through the bottom surface of the heat exchange box 2 and extend to the vicinity of the bottom end inside the heat exchange box 2. An atomizing nozzle 75 communicating with its inner cavity and located below the liquid outlet pipe 5 is fixed on the top surface of the water outlet pipe 74. The two sprockets 77 are connected by a chain 78. The water supply pipe of the external water supply tank is tightly sleeved with the water inlet end of the water pump 72, the external air supply pipe is tightly sleeved with the air inlet pipe 4, and the external liquid pipe is tightly sleeved with the liquid outlet pipe 5. Through the design of the spraying mechanism 7, water mist can be sprayed onto the heat exchange tubes 6, so that the gas inside the heat exchange tubes 6 can be condensed. And through the design of the spraying mechanism 7, the two atomizing nozzles 75 can be driven to rotate while spraying water mist, so that the contact between the water mist and the heat exchange tubes 6 is more sufficient and more uniform, and thus the whole device is more efficient and energy-saving.

[0031] In this embodiment, the spraying mechanism 7 further includes two driving gears 710 meshing with each other between the heat exchange box 2 and the water pipe 71, and a rotating shaft 711 coaxially connected to the output shaft of the motor 79. The two driving gears 710 are respectively coaxially fixed on the circumferential outer walls of the water outlet pipe 74 on the same side and the rotating shaft 711, so that the two sprockets 77 can be smoothly driven to rotate, and then the two water outlet pipes 74 and the two atomizing nozzles 75 can be smoothly driven to rotate.

[0032] In addition, an anti-slip plate 9 with a size adapted to the bottom end of the bottom plate 1 is fixed at the bottom end of the bottom plate 1, and the thickness of the anti-slip plate 9 is 2 - 7 cm, preferably 3 cm in this article, so as to increase the friction between the whole device and the ground, and thus make the whole device more stable during the working process.

[0033] Furthermore, sealing rings are provided at the contact parts of the air inlet pipe 4 with the heat exchange box 2 and the heat exchange tubes 6, sealing rings are provided at the contact parts of the liquid outlet pipe 5 with the heat exchange tubes 6 and the heat exchange box 2, sealing rings are provided at the contact parts of the water inlet pipe 73 with the water pump 72 and the water pipe 71, and sealing rings are also provided at the contact parts of the water outlet pipes 74 with the atomizing nozzles 75 on the same side and the water pipe 71, which can make the sealing performance of the whole device better and prevent the phenomenon of water or gas leakage during the transportation process.

[0034] Specifically, two atomizing nozzles 75 are symmetrically arranged inside the heat exchange box 2, and the distance between the atomizing nozzles 75 and the heat exchange tube 6 is 15-30 cm, preferably 18 cm in this article, so that the water mist sprayed by the two atomizing nozzles 75 can fully contact the heat exchange tube 6.

[0035] It is worth noting that the spray mechanism 7 also includes a protection box 712 fixed on the top surface of the water pipe 71, the motor 79 is located inside the protection box 712, and the rotating shaft 711 passes through the top surface of the protection box 712, which can protect the motor 79 and thus extend the service life of the motor 79.

[0036] It is worth noting that the distance between the protection box 712 and the driving gear 710 on the same side is 5-14 cm, and the distance between the protection box 712 and the water outlet pipe 74 on the same side is 4-10 cm. In this article, the distance between the protection box 712 and the water outlet pipe 74 on the same side is preferably 8 cm, so that the two water outlet pipes 74 and the two sprockets 77 can rotate smoothly, and then the two atomizing nozzles 75 can rotate smoothly.

[0037] Finally, it should be noted that the water pump 72, motor 79, fan 8 and other components involved in the utility model are all universal standard parts or components known to technical personnel in this field, and their structures and principles are all known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0038] In the specific use of this embodiment, when gas evaporation and condensation are required, first, the water supply pipe of the external water supply tank is tightly sleeved with the water inlet end of the water pump 72, the external air supply pipe is tightly sleeved with the air inlet pipe 4, and the external liquid pipe is tightly sleeved with the liquid outlet pipe 5. Then, after ventilation, the water pump 72, the motor 79 and the fan 8 are started through the external PLC. The water pump 72 transports the water in the external water supply tank to the inside of the water inlet pipe 73 through its water supply pipe. The water entering the inside of the water inlet pipe 73 then passes through the water pipe 71 and enters the inside of the two water outlet pipes 74. The water entering the inside of the water outlet pipe 74 then enters the inside of the atomizing nozzle 75 on the same side and is sprayed out.

[0039] Meanwhile, the output shaft of the motor 79 rotates to drive the coaxial rotating shaft 711. The rotation of the rotating shaft 711 drives the same-side driving gear 710 coaxially fixed thereto. The rotation of the driving gear 710 drives the rotation of another driving gear 710 meshing with it. The rotation of the other driving gear 710 drives the rotation of the same-side water outlet pipe 74 coaxially fixed thereto. The rotation of the water outlet pipe 74 drives the rotation of the same-side sprocket 77 coaxially fixed thereto. The rotation of the sprocket 77 drives the rotation of another sprocket 77 coaxially fixed thereto through a chain 78. The rotation of the other sprocket 77 drives the rotation of another water outlet pipe 74 coaxially fixed thereto. The rotation of the water outlet pipe 74 drives the rotation of the same-side atomizing nozzle 75 fixed thereto. The rotation of the two atomizing nozzles 75 can evenly spray water mist onto the surface of the heat exchange pipe 6. After the water mist absorbs heat, it evaporates into water vapor and rises. The fan 8 can disperse the water vapor, and the gas inside the heat exchange pipe 6 is liquefied due to heat release.
