[0028] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Closed-circuit cooling towers primarily rely on the dual cooling effects of sprayed water and air to cool the refrigerant. Their working principle is that the refrigerant circulates within the coils inside the tower, while external sprayed water flows over the surface of these coils. Heat is dissipated through the evaporation of the sprayed water and the airflow. However, as... Figure 1 As shown, in existing closed-loop cooling tower designs, the coils are usually arranged in a serpentine pattern. Although this layout achieves heat exchange to a certain extent, its heat exchange efficiency is not optimal, so there is still room for improvement.

[0030] Based on the above background, this utility model proposes a new cooling tower that can not only significantly improve heat exchange efficiency, but also effectively reduce the overall volume.

[0031] Please refer to the following: Figure 2 , Figure 3The preferred embodiment of this utility model proposes a cooling tower including a tower body and a refrigerant coil component, a fan 1, a spray component, and a water collection component 2 disposed within the tower body. An airflow channel is provided within the tower body, the refrigerant coil component is located in the path of the airflow channel, the fan 1 is located at the air outlet end of the airflow channel, the spray component is located above the refrigerant coil component and is used to spray water onto the refrigerant coil component, and the water collection component 2 is used to collect the water flowing down from the refrigerant coil component. The refrigerant coil component adopts a spiral pipe 301 arranged in a double spiral pattern, and the spiral pipe 301 has a refrigerant inlet end 303 and a refrigerant outlet end 304.

[0032] It should be understood that the cooling principle of this cooling tower is as follows: the refrigerant flows within a closed coil, and heat is conducted through the pipe walls to the external spray water. The spray water evaporates, and the heat is carried away by the airflow. At the same time, in addition to the latent heat of vaporization, there is also sensible heat exchange between the air and the spray water, further reducing the refrigerant temperature.

[0033] Compared to the traditional serpentine arrangement, the refrigerant coil component of this invention adopts a double-helix structure. This structure guides air and spray water to fully contact each other within the helical path, achieving efficient heat exchange. Specifically, this design makes fuller use of the cooling tower's internal space, significantly increasing the contact area between the refrigerant coil and the spray water, thereby improving heat exchange efficiency. Simultaneously, the double-helix arrangement optimizes airflow distribution within the airflow channel, allowing air to flow more evenly through the refrigerant coil component, further enhancing the heat exchange effect. Furthermore, the double-helix arrangement results in a more compact spiral pipe structure, effectively reducing the overall volume of the cooling tower and the equipment's footprint while ensuring efficient heat exchange and improving space utilization. In practical applications, users can flexibly adjust parameters such as the diameter and pitch of the spiral pipe according to specific needs to achieve optimal heat exchange performance and equipment size configuration.

[0034] It should be noted that, Figure 2 A top view of a double-helix spiral pipe 301 is shown. In some alternative embodiments, the double-helix spiral pipe 301 may also be spirally arranged in the vertical cross-sectional direction.

[0035] In the preferred embodiment of this utility model, such as Figure 2 As shown, spiral fins 302 are provided on the outer circumference of the spiral pipe 301. It should be noted that the cross-sectional shape of the spiral fins 302 can be flexibly set according to actual needs, and is not limited here. In a preferred embodiment, the cross-sectional shape of a single fin in the spiral fins 302 is triangular.

[0036] This invention effectively increases the heat exchange area by adding spiral fins 302 to the outer circumferential surface of the spiral pipe 301. Furthermore, the spiral pipe 301 with spiral fins 302 can more efficiently guide the fluid to form turbulence and prolong the contact time between the fluid and the spiral pipe 301, thereby significantly improving heat exchange efficiency.

[0037] In the preferred embodiment of this utility model, such as Figure 3 As shown, the fan 1 is located at the center of the top of the tower; the airflow channel includes an air outlet channel facing the fan 1, and a first air inlet channel and a second air inlet channel located on both sides of the air outlet channel; the spiral pipe 301 includes a first spiral pipe 31 located in the first air inlet channel and a second spiral pipe 32 located in the second air inlet channel, and the first spiral pipe 31 and the second spiral pipe 32 are connected.

[0038] It should be noted that the tower body is provided with air inlets corresponding to the first and second air inlets, and air outlets corresponding to the air outlets. In a preferred embodiment, an air outlet facing the fan is located at the center of the top of the tower body, while the top and sides of the tower body are provided with first air inlets corresponding to the first air inlets. Simultaneously, the top and sides of the tower body are also provided with second air inlets corresponding to the second air inlets. Furthermore, a wind baffle assembly can be installed inside the tower body to separate the first air inlet, the second air inlet, and the air outlet.

[0039] This invention effectively improves heat exchange efficiency by setting up symmetrically distributed first spiral pipes 31 and second spiral pipes 32. This design not only makes the heat exchange process more efficient, but also effectively reduces the size of individual spiral pipes by optimizing the pipe layout, thereby alleviating the temperature gradient problem caused by uneven heat dissipation from individual spiral pipes to a certain extent. Furthermore, this design also has the advantage of reducing the overall height of the equipment, making the overall structure more compact while maintaining high-efficiency cooling performance. This not only facilitates equipment installation but also greatly improves the convenience of transportation.

[0040] In a preferred embodiment of this utility model, such as Figure 3 As shown, there are multiple first spiral pipes 31 and second spiral pipes 32; the multiple first spiral pipes 31 are stacked vertically, and any two adjacent first spiral pipes 31 can be connected by a connecting pipe; the multiple second spiral pipes 32 are stacked vertically, and any two adjacent second spiral pipes 32 can be connected by a connecting pipe.

[0041] This utility model employs a stacked design of the first spiral pipe 31 and the second spiral pipe 32, which guides air and spray water to fully contact each other in the spiral path, thereby achieving more efficient heat exchange.

[0042] In the preferred embodiment of this utility model, such as Figure 3 As shown, the spraying components include a first spraying component 51 and a second spraying component 52 located on the top of the tower and on both sides of the fan 1; the first spraying component includes a first water storage tank and a first spraying pipe connected to the first water storage tank, and a plurality of first nozzles are installed on the side of the first spraying pipe facing the first spiral pipe 31; the second spraying component includes a second water storage tank and a second spraying pipe connected to the first water storage tank, and a plurality of second nozzles are installed on the side of the second spraying pipe facing the second spiral pipe 32.

[0043] This invention, by comprising a first spray component 51 and a second spray component 52 corresponding to the first spiral pipe 31 and the second spiral pipe 32 respectively, enables more precise control of the flow rate and direction of the sprayed water, ensuring that the sprayed water can evenly cover the surfaces of the first spiral pipe 31 and the second spiral pipe 32. This design not only improves the efficiency of heat exchange but also effectively avoids localized overheating caused by uneven spraying. Furthermore, the independent arrangement of the first spray component 51 and the second spray component 52 makes equipment maintenance and repair more convenient and faster, reducing operating costs.

[0044] In a preferred embodiment of this utility model, an ultrasonic atomizing device is provided in the first water tank and the second water tank.

[0045] This invention utilizes ultrasonic atomization technology to transform liquid into tiny droplets. These tiny droplets have a larger surface area, resulting in faster evaporation, higher cooling efficiency, and reduced evaporation loss of spray water, thus lowering water consumption. Simultaneously, the tiny droplets undergo evaporative cooling through a double-helix spiral pipe. The spiral path increases the contact time between air and spray water, and the spiral structure provides a larger heat exchange area. Turbulence within the spiral path enhances heat transfer. Furthermore, by adjusting the ultrasonic frequency and power, the atomization amount and cooling effect can be precisely controlled, making it more suitable for the needs of modern commercial large-scale units.

[0046] In the preferred embodiment of this utility model, such as Figure 3 As shown, the first water storage tank is connected to the water collection component 2 through the first water supply pipeline 61, and the second water storage tank is connected to the water collection component 2 through the second water supply pipeline 62. A water pump 7 is installed on the first water supply pipeline 61 and the second water supply pipeline 62, and flexible joints are also installed on both sides of the water pump 7 for protection.

[0047] This invention connects the first and second water storage tanks to the water collection component, enabling the repeated recycling of water resources that have not been fully consumed, thereby improving water resource utilization efficiency and reducing overall water resource consumption.

[0048] In a preferred embodiment of this invention, a water flow switch 8 for adjusting the water flow rate is provided on the first water supply pipeline 61 and the second water supply pipeline 62. This design allows for more flexible control of water resource allocation and utilization. When increased cooling effect is required, the water flow rate can be increased by opening the water flow switch 8, allowing more water to be atomized and participate in the evaporative cooling process; conversely, when cooling demand is low, the water flow rate can be reduced to conserve water resources. This design not only improves water resource utilization efficiency but also makes this invention more flexible and adaptable in practical applications, better meeting the cooling needs of different scenarios.

[0049] In a preferred embodiment of this invention, the water collection component 2 is a water collection tank located at the center of the bottom of the tower body, and a water level sensor and a temperature sensor are installed inside the water collection tank. This design enables real-time monitoring of the water level and temperature within the water collection tank. The water level sensor accurately detects changes in the water volume within the tank. When the water volume reaches a preset threshold, it automatically triggers a corresponding control mechanism, such as starting or stopping the water pump 7, thereby ensuring that the water volume in the tank remains within a reasonable range, providing a stable water supply to the spray components and preventing water waste or shortage. The temperature sensor monitors the water temperature in the tank in real time, providing necessary data support for temperature adjustment, ensuring that the water temperature is within a suitable range for evaporative cooling before supplying water to the spray components, thus improving cooling efficiency. The overall design further enhances the stability and reliability of the device in practical applications.

[0050] In a preferred embodiment of this utility model, the tower body consists of a detachably connected upper tower body and a lower tower body. A portion of the refrigerant coil assembly, the fan 1, and the spray assembly are installed in the upper tower body, while the remaining portion of the refrigerant coil assembly and the water collection assembly 2 are installed in the lower tower body. This design facilitates separate production and assembly, thereby improving production efficiency and effectively reducing transportation costs. In a preferred embodiment, the refrigerant coil assembly includes five layers of first spiral pipes 31 and five layers of second spiral pipes 32. The uppermost first spiral pipe 31 and the uppermost second spiral pipe 32 of the refrigerant coil assembly are installed in the upper tower body, and the remaining four layers of first spiral pipes 31 and the remaining four layers of second spiral pipes 32 are installed in the lower tower body.

[0051] Building upon the aforementioned introduction to cooling towers, the following section will provide a detailed explanation of their cooling operation process.

[0052] The cooling efficiency calculation model for a cooling tower involves multiple factors, including the temperatures of the fluid being cooled before and after cooling, the ambient wet-bulb temperature, airflow rate, waterflow rate, and latent heat of vaporization. The detailed calculation model and formulas are as follows:

[0053] 1. Definition of cooling efficiency (η): Cooling efficiency represents the ratio of the temperature drop of the fluid to be cooled to the maximum possible temperature drop. The maximum temperature drop is the temperature drop of the fluid to be cooled from its initial temperature to the ambient wet-bulb temperature.

[0054]

[0055] Where t1 is the temperature of the fluid to be cooled before cooling (°C); T2 is the temperature of the fluid to be cooled after cooling (°C); T w The ambient wet-bulb temperature is (°C).

[0056] 2. Calculation of Evaporation Rate (E): Evaporation rate represents the amount of water evaporated in the cooling tower, which carries away heat through the latent heat zone.

[0057]

[0058] Where, m air Airflow rate (kg / s); h fg ω1 and ω2 are the latent heat of vaporization (J / kg); ω1 and ω2 are the inlet and outlet humidity of air (kg / kg dry air); m water c is the water flow rate (kg / s); p is the specific heat capacity of water (J / kg℃).

[0059] 3. Cooling efficiency in conjunction with evaporation rate: Cooling efficiency can also be calculated using sensible heat and latent heat exchange.

[0060]

[0061] This formula takes into account changes in water temperature and air humidity, thus comprehensively reflecting the cooling efficiency.

[0062] As can be seen from the above formulas, the smaller the air flow rate and latent heat of vaporization, and the larger the water flow rate, the higher the efficiency of the cooling tower.

[0063] The cooling tower proposed in this invention uses a double-helix spiral pipe as the refrigerant coil component and incorporates ultrasonic atomization technology. This design features ultra-high energy efficiency and maximizes space utilization in its structure, reducing the overall height of the equipment and making it suitable for more diverse scenarios.

[0064] like Figure 4 As shown, the operating principle of this cooling tower is as follows:

[0065] When the cooling tower is in operation, the water flow switch is turned on, and the water system begins circulation. As the water flows through the ultrasonic atomizing device, the device activates, atomizing the sprayed water into tiny droplets. These droplets then circulate with the system to the refrigerant coil components for evaporative cooling. The air and droplets are guided by a multi-layered, double-helix spiral pipe, ensuring full contact between them and achieving efficient heat exchange. Air rises along the spiral path, creating natural or forced convection. The droplets are sprayed from the top and flow downwards along the spiral structure surface, allowing for full contact between air and droplets, transferring heat from the droplets to the air for further efficient cooling. Simultaneously, the power and frequency of the ultrasonic atomizing device can be adjusted according to the overall system requirements, controlling the atomization amount of the sprayed water droplets, thus achieving self-adjustment and self-adaptation functions for the cooling tower. When the device stops operating, the water flow switch closes, and the water circulation stops. At this time, the descaling function of the ultrasonic device can be activated to effectively clean the scale buildup in the spiral pipes, ensuring the water quality of the circulating water and making it more environmentally friendly and efficient.

[0066] This invention employs a double-helix spiral pipe arrangement for refrigerant coil components, guiding the flow of air and water to ensure full contact between them within the spiral path, achieving efficient heat exchange. Furthermore, with the same contact area, this invention's device is smaller and more compact, saving more installation space and offering higher heat exchange efficiency, making it suitable for the structural planning and requirements of modern commercial large-scale units. In addition, ultrasonic atomization technology is used to atomize water into tiny droplets, which are then rapidly evaporated and cooled by airflow. This invention further enhances cooling efficiency by optimizing the airflow path and atomization effect, making it suitable for scenarios with high cooling performance requirements.

[0067] In summary, the cooling tower proposed in this invention can achieve efficient heat exchange, and the equipment has advantages such as energy saving and small size. Therefore, it can be applied to more scenarios such as industrial cooling, data centers, and commercial buildings, improving the reliability, safety, and practicality of the system.

[0068] Furthermore, the cooling tower proposed in this utility model can be applied to refrigeration systems, such as air conditioning systems. The refrigeration system includes a refrigerant circulation loop formed by a compressor, condenser, evaporator, and throttling valve. The cooling tower is connected to the refrigerant circulation loop. One refrigerant gas pipe 91 is connected to the refrigerant inlet end 303 of the refrigerant coil component, and one refrigerant liquid pipe 92 is connected to the refrigerant outlet end 304 of the refrigerant coil component.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
