This utilizes the heat absorption of water evaporation to achieve efficient condensation cooling. The suction fan enhances airflow circulation, accelerates water evaporation and heat exhaust, and significantly improves the unit's cooling efficiency.

At the same time, the triangular guide block guides the spray wastewater back to the water collection chamber, realizing water resource recycling and reducing energy consumption and water waste. 2. This invention links the intelligent water control system with the mixing device and the control system. The control panel can intelligently send control signals to drive the electric push rod to extend and retract the water control device. The spray water volume is precisely adjusted through the cooperation of the sealing block and the tension sleeve, flexibly adapting to different cooling load requirements. At the same time, the spiral blades of the mixing device stir the water collection chamber to recover water, avoiding impurities from accumulating and clogging the pipes, ensuring uniform water temperature. The filter screen intercepts external impurities, and the partition plate divides the internal space of the unit, further improving the unit's operational stability and service life. It solves the problems of inconvenient water volume adjustment, easy impurity accumulation, cumbersome maintenance, and poor operational stability in the prior art, realizing intelligent, efficient, and stable operation of the unit throughout the entire process. Moreover, the threaded connection design of the connecting sleeve and the diversion shroud facilitates component maintenance and repair, reducing operation and maintenance costs.

[0023] like Figure 5 As shown, the water control device 36 includes a fixing block 361 disposed inside the water collection tank 35. A connecting rod 363 is fixedly connected to the rear end of the fixing block 361, and the rear end of the connecting rod 363 extends outside the water collection tank 35. The end of the connecting rod 363 located outside the water collection tank 35 is U-shaped and fixedly connected to the electric push rod 37. Multiple sealing blocks 362 that fit with the pipes of the water collection tank 35 are sleeved on the outer wall of the end of the connecting rod 363 located inside the water collection tank 35. Tension sleeves 364 are fixedly connected between the sealing blocks 362 and between the sealing blocks 362 and the fixing block 361. The sealing blocks 362 and the tension sleeves 364 cooperate to ensure the sealing performance during the water control process, prevent the spray water from leaking, and realize the flexibility of tension adjustment, ensuring accurate and stable water volume adjustment and improving the reliability of water control.

[0024] like Figure 2 As shown, the mixing device 4 includes a motor 41 fixedly installed on the outer wall of the rear end of the frame 1. The output end of the motor 41 is fixedly connected to a rotating shaft 42, and the other end of the rotating shaft 42 extends through the outer wall of the frame 1 into the water collection chamber 16. A spiral blade 43 is connected to the outer wall of the end of the rotating shaft 42 located inside the water collection chamber 16. The spiral blade 43 rotates and stirs the recycled water in the water collection chamber 16 to prevent impurities in the water from accumulating and clogging the pipes. At the same time, it makes the water temperature uniform, improves the stability and continuity of spray cooling, and extends the service life of the unit.

[0025] like Figure 1 and Figure 4 As shown, the control system 2 includes a control console 21 with a smart chip, which is fixedly installed on the front outer wall of the frame 1, and a signal receiver 22 fixedly installed on the rear end of the electric push rod 37. The control console 21 has a built-in signal generator. The control console 21 is linearly connected to the motor 41 and the electric push rod 37 to realize intelligent linkage control. The intelligent control console 21 cooperates with the signal transceiver mechanism to realize the linkage intelligent control of the motor 41 and the electric push rod 37, eliminating the need for manual adjustment, improving the convenience of unit operation, and realizing automated and intelligent operation.

[0026] like Figure 2As shown, the inner wall of the mounting frame 14 is provided with a fixed step 141 for placing the cooler 6, and a guide block 142 is fixedly connected to the inner edge of the lower end of the mounting frame 14; the guide block 142 is triangular in shape, and the guide end extends to the water outlet at the lower end of the mounting frame 14; the fixed step 141 enables the cooler 6 to be quickly positioned and installed, and the triangular guide block 142 guides the spray wastewater to flow quickly into the water collection chamber 16, avoiding water accumulation and blockage, and improving the convenience of unit maintenance and operational stability.

[0027] like Figure 2 and Figure 3 As shown, the airflow guiding mechanism 7 includes an airflow guiding box 71 fixedly connected inside the cooling chamber 19, and an airflow guiding hood 73 fixedly installed on the front side of the mounting frame 14; the pipe opening of the airflow guiding hood 73 extends into the mounting frame 14 to achieve directional airflow guidance; the airflow guiding box 71 and the airflow guiding hood 73 cooperate to achieve directional airflow guidance of the cooling airflow, so that the airflow acts precisely on the surface of the cooler 6, enhances the evaporative cooling effect, reduces airflow loss, and improves cooling efficiency.

[0028] like Figure 3 As shown, the upper end of the flow box 71 is provided with a through port 711 corresponding to the output end of the fan unit 5. A connecting sleeve 72 is integrally formed on the outer wall of the flow box 71 near the flow hood 73. A suction fan is fixedly installed inside the connecting sleeve 72. The connecting sleeve 72 extends into the flow hood 73 to realize enhanced airflow guidance. The suction fan and the connecting sleeve 72 cooperate to enhance the airflow delivery force, accelerate the evaporation rate of the surface of the cooler 6, further improve the cooling efficiency of the unit, and adapt to high load cooling requirements.

[0029] like Figure 3 As shown, the outer wall of the connecting sleeve 72 is provided with external threads. The connecting sleeve 72 extends into the inside of the pipe of the diversion hood 73 and is fixedly connected to the diversion hood 73 through the internal and external thread engagement, realizing detachable assembly. The threaded connection enables quick disassembly and assembly of the connecting sleeve 72 and the diversion hood 73, which facilitates the maintenance, repair and replacement of the suction fan and the diversion hood 73, reduces the unit maintenance cost and improves the convenience of equipment operation and maintenance.

[0030] Working principle of Example 1: Outside air is filtered through the filter screen of the air inlet 11 at the rear end of the frame 1 and then enters the air inlet chamber 15. The fan unit 5 is started and the airflow is directed to the surface of the cooler 6 through the flow guide mechanism 7. The water control system 3 sprays the recycled water from the water collection chamber 16 onto the cooler 6, and uses the heat absorption of water evaporation to cool the cooler 6. The wastewater after spraying flows into the water collection chamber 16 through the guide structure. The mixing device 4 stirs the water to prevent impurities from settling and realizes water resource recycling. The control system 2 intelligently controls the operation of each component to adapt to different cooling needs.

[0031] Spray cooling is a method for the unit to achieve efficient cooling. The spray pump 31 draws recycled water from the water collection chamber 16 and delivers it to the distribution box 33 through the connecting pipe 32. The distribution box 33 evenly distributes the water to multiple distribution pipes 34 and then delivers it to the water collection tank 35 to achieve equal distribution of water volume. The water control device 36 in the water collection tank 35 adjusts the water flow rate according to the cooling load requirements and delivers it to the spray pipe 121 through the connecting port 351. Multiple spray heads 122 at the lower end of the spray pipe 121 spray water evenly and finely onto the surface of the cooler 6. After the water comes into full contact with the cooler 6, it evaporates quickly and absorbs the heat of the medium in the cooler 6, thereby achieving condensation cooling. The wastewater after spraying flows quickly into the water collection chamber 16 along the triangular guide block 142 of the mounting frame 14 to complete one cycle, realizing the reuse of water resources and reducing energy consumption.

[0032] The core function of the airflow guide is to ensure that the cooling airflow acts precisely and efficiently on the surface of the cooler 6, thereby improving the evaporative cooling efficiency. After the fan unit 5 starts, it sends the filtered air from the outside into the air intake box 71 of the cooling chamber 19. The port 711 on the air intake box 71 is precisely connected to the output end of the fan unit 5 to ensure that all the airflow enters the air intake box 71. A suction fan is installed in the connecting sleeve 72 on one side of the air intake box 71. After the suction fan starts, it strengthens the airflow delivery force and delivers the airflow in the air intake box 71 to the air intake hood 73 at high speed. The pipe opening of the air intake hood 73 extends into the mounting frame 14 to guide the airflow to the surface of the cooler 6, so that it can fully contact the water sprayed on the cooler 6, accelerate the evaporation of water, and at the same time remove the heat generated by evaporation, further improving the cooling effect. The connecting sleeve 72 and the air intake hood 73 are connected by threads, which can be flexibly disassembled and installed, making it easy to maintain the suction fan and the air intake hood 73.

[0033] Intelligent water control enables dynamic adjustment of the spray water volume to adapt to different cooling loads. The control panel 21 (with built-in intelligent chip and signal generator) sends control signals, which are received by the signal receiver 22 at the rear of the electric push rod 37. The electric push rod 37 drives the water control device 36 to extend and retract according to the signal. The connecting rod 363 of the water control device 36 drives the fixed block 361 and the sealing block 362 to move. The sealing block 362 fits into the pipe of the water collection tank 35. The movement of the sealing block 362 changes the pipe conduction area, thereby adjusting the spray water volume (the water volume decreases when the sealing block 362 is in contact with the pipe and increases when it is away from the pipe). The tension sleeve 364 between the sealing blocks 362 can be flexibly stretched while ensuring sealing performance to prevent spray water leakage and ensure accurate and stable water volume adjustment. The control panel 21 is linearly linked with the motor 41 and the electric push rod 37, which can synchronously control the mixing device 4 and the water control device 36 to achieve intelligent operation of the entire process.

[0034] Mixing device 4: Motor 41 drives the rotating shaft 42 and spiral blades 43 to rotate, stirring the recycled water in the water collection chamber 16 to prevent impurities in the water from accumulating and clogging the pipes, while also ensuring uniform water temperature and stable spray cooling; Filter screen: intercepts dust and impurities in the outside air to prevent them from entering the unit and clogging the pipes and contaminating the cooler 6, thus extending the service life of the unit; Partition plate 18: divides the inside of the frame 1 into the air guide chamber 17, the air inlet chamber 15 and the water collection chamber 16, ensuring that each part does not interfere with each other and improving the orderly operation of the unit.
