[0001] This invention relates to the field of water cooling technology, specifically to an auxiliary closed-loop circulating water water-saving and energy-saving cooling system based on a combination of dry and wet cooling. Background Technology

[0002] With the development and progress of industrial production, a large amount of energy is consumed, and a large amount of heat energy is also generated. During the production process, many pieces of equipment require cooling water to lower the temperature and maintain normal operation, which leads to a continuous increase in water and energy consumption. However, existing cooling water systems have a single operating mode and are difficult to cope with the cooling needs of different environments, especially cooling systems based on evaporative air cooling technology, which have high water consumption and low heat exchange efficiency.

[0003] Therefore, it is necessary to provide a water-saving and energy-efficient cooling system based on a dry-wet combined auxiliary closed-loop circulating water system to solve the problems mentioned in the background art. Summary of the Invention

The tower body has an air inlet end on its periphery, which is equipped with a louvered fan. The top of the tower body has an air outlet end. A heat exchange tube assembly connected in series with the second tube body is arranged between the air inlet end and the air outlet end. The first spray assembly is located above the heat exchange tube assembly, and the second spray assembly is located below the heat exchange tube assembly.

[0006] Furthermore, as a preferred embodiment, the louvered fan uses galvanized steel louvers.

[0007] Furthermore, as a preferred embodiment, the heat exchange tube assembly includes multiple heat exchange tubes arranged in parallel, and the heat exchange tubes are serpentine.

The mounting frame is provided with multiple spray heads on the side near the heat exchange tube assembly, and each spray head corresponds to a heat exchange tube.

The auxiliary spray component in the first spray assembly can spray the right side of the heat exchange tube, and the auxiliary spray component in the second spray assembly can spray the left side of the heat exchange tube.

[0009] Furthermore, as a preferred embodiment, both the first spray assembly and the second spray assembly further include a drive base, a telescopic rod, a first corrugated pipe, and a second corrugated pipe. The left side of the drive base is connected to the mounting frame via the first corrugated pipe, and the right side of the drive base is connected to the mounting frame via the second corrugated pipe. Telescopic rods are also embedded on the left and right sides of the mounting frame, and the telescopic ends of the telescopic rods are connected to the drive base.

[0010] A liquid supply chamber is provided in the middle of the drive seat, and a liquid supply through hole is provided on the side of the liquid supply chamber near the auxiliary spray assembly. The liquid supply through hole is sealed and connected to the liquid inlet of the auxiliary spray assembly by a first sealing ring.

[0027] Please refer to Figures 1-6. In this embodiment of the invention, a water-saving and energy-saving auxiliary machine closed-loop circulating water cooling system based on dry and wet combination is provided, including a main unit intercooling tower 1 and a user terminal 3 connected in series on a first pipe body 2 to form a closed loop. A second pipe body 6 is also connected in parallel on the first pipe body 2, and a dry air cooling tower 4 and an evaporative air cooling tower 5 are connected in series on the second pipe body 6.

[0028] It should be explained that multiple valves and pumps are installed on both the first pipe body 2 and the second pipe body 6, so that the water can flow either on the first pipe body 2 or on the second pipe body 6.

[0029] During implementation, the operating mode is as follows:

[0030] (1) When the temperature is above 20℃, the equipment enters the air-cooled + evaporative cooling (i.e., dry and wet combined series) mode:

[0031] When the ambient temperature exceeds 20℃, dry air cooling cannot meet the process cooling requirements, and evaporative cooling must be used for cooling. At this time, the main air cooling tower 1 is in a shutdown state, while the dry air cooling tower 4 and the evaporative air cooling tower 5 are in a working state. Priority is given to increasing the fan frequency in the dry air cooling tower 4, and then the water supply capacity of the evaporative air cooling tower 5 is gradually increased. The fan frequency in the evaporative air cooling tower 5 is adjusted according to the set temperature of the effluent process, so as to meet the process cooling requirements while achieving water-saving and energy-efficient operation.

[0032] (2) When the temperature is below 20℃, the equipment switches to the main unit cooling tower cooling mode through the valve.

[0033] (3) Water-saving operation: prioritize the use of dry air cooling to cool the circulating water, make full use of the temperature rise of the air to bear the heat dissipation load of the cooling water, and minimize the water consumption due to evaporation.

[0034] In this embodiment, the evaporative air-cooled tower 5 includes a tower body 51, a heat exchange tube assembly 55, a first spray assembly 56, and a second spray assembly 57. The tower body 51 has an air inlet end on its periphery, and a louvered fan 52 is provided at the air inlet end. The top of the tower body 51 has an air outlet end. A heat exchange tube assembly 55 connected in series with a second tube body 6 is provided between the air inlet end and the air outlet end. The first spray assembly 56 is located above the heat exchange tube assembly 55, and the second spray assembly 57 is located below the heat exchange tube assembly 55.

[0035] By configuring two spray components, namely the first spray component and the second spray component, the heat exchange tube group 55 can be fully covered by spray, thus ensuring the effect of evaporative air cooling.

[0036] As a preferred embodiment, the louvered fan uses galvanized sheet louvers, which are reliable and durable, and prevent water splashing and loss.

[0037] To improve the heat exchange effect, the heat exchange tube group 55 includes a plurality of heat exchange tubes 551 arranged in parallel, and the heat exchange tubes 551 are serpentine.

[0038] In this embodiment, the first spray assembly 56 and the second spray assembly 57 have the same structure, both including a mounting frame 561, spray heads 562, and auxiliary spray assembly 563. The mounting frame 561 is provided with a plurality of spray heads 562 on the side near the heat exchange tube group 55, and the spray heads 562 are respectively corresponding to the heat exchange tubes 551. An auxiliary spray assembly 563 is also provided on one side of the spray head 562 and is hinged to the mounting frame 561. The auxiliary spray assembly in the first spray assembly 56 can spray the right side of the heat exchange tube 551, and the auxiliary spray assembly in the second spray assembly 57 can spray the left side of the heat exchange tube 551.

[0039] It should be understood that, in order to enable the auxiliary spray component in the first spray assembly 56 to spray the right side of the heat exchange tube 551 and the auxiliary spray component in the second spray assembly 57 to spray the left side of the heat exchange tube 551, the first spray assembly 56 and the second spray assembly 57 should be arranged in a centrally symmetrical manner.

[0040] The first spray assembly 56 and the second spray assembly 57 each include a drive base 564, a telescopic rod 567, a first corrugated pipe 568 and a second corrugated pipe 569. The left side of the drive base 564 is connected to the mounting frame 561 via the first corrugated pipe 568, and the right side of the drive base 564 is connected to the mounting frame 561 via the second corrugated pipe 569. The left and right sides of the mounting frame 561 are also embedded with telescopic rods 567, and the telescopic ends of the telescopic rods 567 are connected to the drive base 564.

[0041] The drive seat 564 has a liquid supply chamber 565 in the middle. The liquid supply chamber 565 has a liquid supply through hole on the side near the auxiliary spray assembly. The liquid supply through hole is sealed and connected to the liquid inlet of the auxiliary spray assembly 563 by a first sealing ring 5611.

[0042] The first sealing ring 5611 is elastic;

[0043] The mounting frame 561 is hinged to the auxiliary spray assembly 563 using a hinged arc seat 566.

[0044] It should be explained that while spraying water onto the surface of the heat exchange tubes can lower the temperature through evaporative cooling, it can also potentially generate scale. This is mainly because dissolved gases, hardness substances, organic matter, microorganisms, and other factors in the water can accumulate on the surface and form scale. Additionally, the salinity of the water can also affect scale formation. This scale can easily impair the heat exchange efficiency.

[0045] In this embodiment, during implementation, the position of the drive seat 564 can be changed by adjusting the extension and retraction of the telescopic rod 567, thereby driving the auxiliary spray assembly 563 to deflect, so that the auxiliary spray assembly 563 sprays at different spray angles, thereby achieving spraying at different height positions of the heat exchange tube. This spraying can help achieve full water coverage of the heat exchange tube, and the high spraying intensity can clean the surface of the heat exchange tube, preventing dirt from affecting the heat exchange effect.

[0046] In a preferred embodiment, the second bellows 569 is filled with an elastic pad.

[0047] In this embodiment, the auxiliary spray assembly 563 includes a spray pipe body 5631 and a nozzle 5632. The spray end of the spray pipe body 5631 is connected to the nozzle 5632. An arc seat 5633 is sleeved on the outside of the spray pipe body 5631 for hinged connection with the hinged arc seat 566. A second sealing ring 5612 is also sleeved on the outside of the spray pipe body 5631 and abuts against the surface of the first sealing ring 5611.

[0048] In this embodiment, an inner ring seat 5634 is provided on the inner wall of the spray pipe body 5631, and a ring bladder 5635 is attached to the inner surface of the inner ring seat 5634.

[0049] The first bellows 568 is filled with liquid and is connected to the main pipe, which is connected to the annular bladder 5636 via a branch pipe 5610.

[0050] In this embodiment, in the initial stage, the nozzle 5632 is oriented close to the first end of the heat exchange tube 551, and the first end of the heat exchange tube 551 is the end close to the nozzle 5632.

[0051] It is particularly important to note that in the initial stage, the nozzle 5632 is oriented close to the first end of the heat exchange tube 551, which is the end close to the nozzle 5632. When the drive seat is moved and the first corrugated pipe 568 is compressed by the telescopic rod, the drive seat can adjust the spray angle of the auxiliary spray assembly 563, that is, adjust the orientation of the nozzle 5632 so that its orientation gradually moves away from the first end of the heat exchange tube 551. At this time, although the distance between the point where the liquid sprayed by the nozzle falls on the heat exchange tube 551 and the nozzle increases, the first corrugated pipe 568 is compressed and is filled with liquid. The first corrugated pipe 568 is connected to the main pipe, which is connected to the ring bladder 5636 through the branch pipe 5610. Therefore, the ring bladder will expand, thereby reducing the water volume in the spray tube body 5631 and increasing the water pressure. This ensures that the liquid falling on the heat exchange tube 551 can still clean the surface of the heat exchange tube with a relatively constant water pressure.

[0052] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
