DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment 1

[0025] like Figure 1 and Figure 2As shown, the first embodiment of the present invention proposes a modular evaporative air cooler, which is used to reduce the temperature of the medium input into the modular evaporative air cooler to achieve the purpose of cooling or condensing the medium.

[0026] Please refer to Figure 1 and Figure 2 The modular evaporative air cooler includes a box body, on which a water tank 5, an evaporative tube bundle group 4, a spray assembly 3, a precooling tube bundle 2 and a fan assembly 1 are arranged in sequence from bottom to top. The evaporative tube bundle group 4 includes a plurality of evaporative tube bundle units 11, and the evaporative tube bundle unit 11 includes a first tube box group 9, a heat exchange tube 10 and a second tube box group 8 which are connected in sequence, wherein the first tube box group 9 and the second tube box group 8 are respectively located on opposite sides of the box body, and the axis of the heat exchange tube 10 is a straight line passing through the first tube box group 9 and the second tube box group 8 respectively, and a connecting pipe 12 is arranged on the first tube box group 9, and the end of the connecting pipe 12 away from the first tube box group 9 is connected to the precooling tube bundle 2, and the connecting pipe 12 is used to introduce the medium precooled by the precooling tube bundle 2 into the corresponding evaporative tube bundle unit 11 for cooling, so as to divert the medium in the precooling tube bundle 2 to each of the evaporative tube bundle units 11.

[0027] Specifically, the number of the evaporator tube bundle units 11 in the evaporator tube bundle group 4 in the modular evaporative air cooler provided in this embodiment can be flexibly set according to actual needs, and the heat exchange tubes 10 in the evaporator tube bundle units 11 are all connected to the first tube box group 9 and the second tube box group 8 by straight tubes, which is convenient for transportation and installation. At the same time, a single evaporator tube bundle unit 11 can be removed from the bottom of the box for maintenance, which is convenient for troubleshooting the leakage points on the heat exchange tube 10 during maintenance, and thus convenient for maintenance of the modular evaporative air cooler; each of the evaporator tube bundle units 11 in the modular evaporative air cooler is separately connected to the pre-cooling tube bundle 2, so that the medium passing through the pre-cooling tube bundle 2 can be dispersed into each of the evaporator tube bundle units 11, thereby dispersing the processing volume of the medium and making the pressure drop of the medium in each of the evaporator tube bundle units 11 lower, which is beneficial to improving the cooling effect of the medium while extending the service life of the equipment.

[0028] like Figure 2As shown, the modular evaporative air cooler further includes an input pipe 6 and an output pipe 7, wherein the input pipe 6 is in communication with the precooling tube bundle 2, and the output pipe 7 is in communication with the first tube box group 9. The input pipe 6 is used to introduce the medium to be cooled into the precooling tube bundle 2, and the output pipe 7 is used to discharge the cooled medium out of the evaporative tube bundle unit 11, and the input pipe 6, the connecting pipe 12 and the output pipe 7 are respectively in communication with the precooling tube bundle 2 and the evaporative tube bundle unit 11 by using bent pipes, so that the input pipe 6, the connecting pipe 12 and the output pipe 7 extend in a direction away from the box body, thereby alleviating the influence of the thermal stress generated when the medium flows in the input pipe 6, the connecting pipe 12 and the output pipe 7 on the modular evaporative air cooler.

[0029] like Figure 2 As shown, the heat exchange tube 10 includes a steel inner tube and an aluminum outer tube, and the aluminum outer tube wraps the steel inner tube. The heat exchange tube 10 uses an aluminum outer tube composited on the outer side of the steel inner tube so that the steel inner tube and the aluminum outer tube are combined into a whole, so that a layer of aluminum layer with uniform thickness is attached to the outer side of the steel inner tube, thereby improving the corrosion resistance of the heat exchange tube 10 and extending the service life of the evaporation tube bundle unit 11.

[0030] Please refer to Figure 1 , the first pipe box group 9 includes at least one pipe box and includes at least one of a plug-in pipe box, a removable cap-type pipe box, a removable cover-plate type pipe box and a welded pipe box, and the second pipe box group 8 includes at least one pipe box and includes at least one of a plug-in pipe box, a removable cap-type pipe box, a removable cover-plate type pipe box and a welded pipe box. The type and quantity of the pipe boxes in the first pipe box group 9 and the second pipe box group 8 can be selected according to actual working conditions, and when the first pipe box group 9 includes multiple pipe boxes, it can be composed of a single type of pipe box or different types of pipe boxes, and when the second pipe box group 8 includes multiple pipe boxes, it can be composed of a single type of pipe box or different types of pipe boxes. The number and type of the pipe boxes used can be flexibly selected and can meet the use requirements. In this embodiment, the first pipe box group 9 and the second pipe box group 8 respectively use plug-in pipe boxes.

[0031] Please combine Figure 1 and Figure 2The spray assembly 3 includes a water pump and a spray pipe connected to the water pump. The water pump is connected to the water tank 5. The spray pipe extends above the evaporation tube bundle group 4 and is provided with a spray head facing the evaporation tube bundle group 4. The water pump is used to pump the water in the water tank 5 into each of the spray heads along the spray pipe, and spray the water onto the heat exchange tubes 10 in each of the evaporation tube bundle units 11 through the spray heads to form a water film on the surface of the heat exchange tubes 10, and the water not attached to the heat exchange tubes 10 falls into the water tank 5, so as to improve the utilization rate of water resources.

[0032] In detail, the fan assembly 1 includes at least two exhaust fans, which are arranged in a row on the box. In this embodiment, the box is provided with four exhaust fans, and the four exhaust fans respectively generate flowing airflows to accelerate the evaporation of the water film on the surface of the heat exchange tube 10, so as to improve the air cooling effect.

[0033] like Figure 1 and Figure 2 As shown, the working process of the modular evaporative air cooler provided in this embodiment is: the medium to be cooled enters the precooling tube bundle 2 through the input pipe 6, and the flowing airflow blown out by the fan assembly 1 acts on the precooling tube bundle 2 for air cooling. The air-cooled medium then enters the corresponding evaporative tube bundle unit 11 through each of the connecting pipes 12, and the spray assembly 3 is used to spray water on the heat exchange tube 10 to form a water film on the surface of the heat exchange tube 10. At the same time, the flowing airflow blown out by the fan assembly 1 accelerates the vaporization of the water film on the surface of the heat exchange tube 10, thereby performing water cooling. The cooled medium is discharged from the evaporative tube bundle unit 11 from the output pipe 7.
