Description

Technical Field

[0001] This invention belongs to the technical field of heat exchange equipment, specifically relating to a wet air cooler for eliminating fogging peaks. Background Technology

[0002] As a common heat exchange device in the industrial field, wet air coolers are widely used in circulating water cooling scenarios in industries such as power and chemical engineering. They achieve cooling of process media through direct contact between sprayed water and air and by using evaporative heat exchange. To adapt to different ambient temperatures and operating load conditions, existing wet air coolers usually have evaporator coils installed inside the casing, along with a spray system, air inlet louvers, and defogging devices to meet requirements for cooling, antifreeze, and environmental emissions.

[0003] In the prior art, the wet air cooler solutions disclosed in patent documents such as CN120627728A, CN120426784A and CN120333187B mostly adopt a cross-flow evaporator coil structure, that is, air passes through the evaporator coil in a horizontal direction to complete heat exchange. This structure can achieve basic cooling function under normal operating conditions, but usually requires a large static pressure chamber and fan structure inside the equipment, resulting in a large overall footprint. At the same time, in condensation or anti-freeze operation scenarios, since the condensate or cooling medium needs to be discharged under gravity, the heat exchange tubes often need to be arranged at an angle. However, after the cross-flow evaporator coil is arranged at an angle, it is prone to uneven airflow distribution, increased air leakage and decreased heat exchange efficiency, and may even lead to localized dry spots and corrosion of the heat exchange tubes.

[0004] To meet cooling requirements under extreme operating conditions (high ambient temperature, overload operation, etc.), the existing technologies described above use peak cooling structures to introduce outside air for enhanced cooling of the spray water. However, these peak cooling structures are mostly relatively independent functional units. In non-peak operating modes, their corresponding airflow channels usually need to be closed, making them difficult to reuse in other operating conditions, resulting in the structure remaining idle for extended periods. When defogging is required, additional independent fresh air louvers or make-up air channels need to be installed on the equipment, increasing not only the complexity of the equipment structure and manufacturing costs but also the risk of air leakage due to increased openings in the housing. Furthermore, existing equipment suffers from problems such as high air resistance and increased energy consumption due to the cross-flow arrangement of the evaporator coils, water waste caused by the spray water from the peak device easily entering the mixing chamber and dispersing, and equipment damage caused by the freezing of the heat exchange medium in low-temperature environments. All of these issues restrict the performance improvement and application expansion of existing wet air coolers. Summary of the Invention

[0005] This invention provides a defogging peak wet air cooler to solve the problems mentioned in the background art, such as the defects in the evaporator coil arrangement, the difficulty in reusing the peak cooling structure under non-peak conditions, and the reliance on an additional air supply structure for defogging operation, which lead to complex equipment structure and high energy and water consumption.

[0006] The technical solution adopted in this invention is: a fog-reducing peak wet air cooler, including a housing, an installation chamber that runs vertically through the interior of the housing, an evaporator coil installed in the installation chamber, a first chamber connected to the installation chamber at the bottom of the inner cavity of the housing, and antifreeze louvers installed on the side wall of the housing where the first chamber is located.

[0007] A spike device is installed in the inner cavity of the box and near the side wall of the box. A spike louver is installed on the side wall of the box near the spike device. A second chamber is formed in the inner cavity of the box. The second chamber is located in the area outside the installation chamber. Air entering the inner cavity of the box from the spike louver can enter the second chamber after passing through the spike device.

[0008] At least one diamond-shaped anti-fogging packing is installed inside the housing and above the evaporator coil. Air flowing from bottom to top from the installation chamber and air flowing from the second chamber can pass through the diamond-shaped anti-fogging packing and eventually be discharged to the outside of the housing.

[0009] There are two rhomboid anti-fogging fillers, which are positioned above the outside of the installation chamber. A drag-reducing louver is installed between the two rhomboid anti-fogging fillers. A third chamber is connected above the installation chamber. The third chamber is located within the area enclosed by the two rhomboid anti-fogging fillers and the drag-reducing louver. The hot air passage of the two rhomboid anti-fogging fillers is connected to the third chamber, and the cold air passage of the two rhomboid anti-fogging fillers is connected to the second chamber.

[0010] There are four rhomboid anti-fogging fillers, which are connected in sequence and each has a flow divider at its lower end. The four flow dividers divide the space above the installation chamber into an outer third chamber and a middle fifth chamber. Both the third and fifth chambers are connected to the installation chamber where the evaporator coil is located. An airflow distribution louver is installed at the lower end of the fifth chamber, and a makeup air louver is installed on the side wall of the housing where the fifth chamber is located. The cold air channels of the two rhomboid anti-fogging fillers located on both sides are connected to the second chamber.

[0011] The inner cavity of the box is formed with a mixing chamber above the rhomboid anti-fogging packing. The hot air channel and cold air channel of the rhomboid anti-fogging packing are both connected to the mixing chamber.

[0012] An exhaust fan is installed on the top of the enclosure.

[0013] It also includes a hot water tank and a cold water tank located at the bottom of the enclosure. The hot water tank is used to collect the hot water that falls back from the evaporator coil, and the cold water tank is used to collect the cold water that falls back from the peak device.

[0014] It also includes an evaporator coil spray device and a peak spray device. The evaporator coil spray device is used to transport and spray cold water from the cold water tank onto the evaporator coil, and the peak spray device is used to transport and spray hot water from the hot water tank onto the peak device.

[0015] The hot water tank is located at the bottom of the tank, near the center, while the cold water tank is located at the bottom of the tank. A guide pipe is provided below the peak device, which is configured to guide the cold water falling from the peak device to the cold water tank.

[0016] A water collector is installed inside the installation chamber and above the evaporator coil.

[0017] It also includes a fourth chamber, which is formed in the area between the peak device and the cold water pool, and the fourth chamber is connected to the first chamber.

[0018] The heat exchange tubes on the evaporator coil are arranged at an angle.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention adopts a counter-flow evaporator coil arrangement, which allows air to pass through the installation chamber from bottom to top and exchange heat with the evaporator coil. Compared with the traditional cross-flow arrangement, it has a higher heat exchange efficiency and can smoothly discharge condensate or cooling medium under condensation conditions or anti-freeze operation scenarios, avoiding local dry spots and corrosion problems. In addition, the counter-flow arrangement does not require a large static pressure chamber, which reduces wind resistance, increases system throughput, and significantly reduces the equipment footprint, which is conducive to compact layout in industrial sites.

[0021] 2. This invention connects the second chamber to the cold air channel of the diamond-shaped defogging packing, allowing outside air to enhance the cooling of the spray water during peak cooling mode; the peak channel can be closed during non-peak or defogging operation; in defogging mode, outside air can enter the cold air channel of the diamond-shaped defogging packing through the peak device and the second chamber to participate in heat exchange, eliminating the need for additional independent air supply louvers on the equipment, simplifying the equipment structure, reducing manufacturing costs and minimizing the risk of air leakage.

[0022] 3. Energy saving and consumption reduction: By setting up drag-reducing louvers, the overall air resistance of the equipment is effectively reduced. In peak mode and energy-saving mode, with the specific louver opening and closing logic, the energy consumption of the exhaust fan can be significantly reduced, achieving energy-saving operation of the equipment.

[0023] 4. Anti-fogging and environmentally friendly: The design of the hot and cold air channels using diamond-shaped anti-fogging filler allows for heat exchange between the humid and hot air and the fresh air in anti-fogging mode. This reduces the moisture content and relative humidity of the humid and hot air, keeping it away from saturation. As a result, it avoids the formation of white fog after mixing with the ambient air, reducing visual pollution and meeting environmental protection requirements.

[0024] 5. Water-saving and efficient: The guide pipe design at the bottom of the peaking device avoids mixing of hot and cold water. Furthermore, in energy-saving mode, evaporation is reduced to zero when the peaking device is shut down, minimizing spray water loss; the optimized spray water circulation path further improves water resource utilization efficiency.

[0025] 6. Anti-freeze protection: In low-temperature anti-freeze mode, by closing all louvers and stopping related devices, a "natural warm room" is formed inside the equipment, using the residual heat of the medium to maintain the internal temperature, preventing the heat exchange medium from freezing, and ensuring the safety and reliability of the equipment in severe cold environments.

[0026] 7. Multi-mode adaptation: The equipment has four operating modes: peak, energy saving, defogging, and antifreeze. It can be flexibly switched according to the ambient temperature and load requirements, which can not only meet the cooling requirements of peak conditions, but also adapt to the energy saving and environmental protection requirements of different operating conditions, making it suitable for a wide range of scenarios.

[0027] 8. Structural optimization: The spray water from the evaporator coil is further away from the side wall of the water tank, reducing the risk of water drift and adhesion; the coordinated design of the peak device and the main heat exchange structure not only expands the equipment functions but also ensures the stability of the heat exchange process and improves the overall performance of the equipment.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figure 1-4 As shown, a fog-reducing peak wet air cooler includes a housing 1. The housing 1 has a vertically penetrating installation chamber 106 inside. Specifically, two support plates 18 are vertically arranged in the middle of the housing 1, forming the vertically penetrating installation chamber 106 between the two support plates 18 and the side wall of the housing 1. An evaporator coil 3 is installed inside the installation chamber 106. A first chamber 101, connected to the installation chamber 106, is located below the inner cavity of the housing 1. Anti-freeze louvers 11 are installed on the side wall of the housing 1 where the first chamber 101 is located. The heat exchange tubes on the evaporator coil 3 are arranged at an angle. Compared to the arrangement of a cross-flow evaporator coil, this embodiment adopts a counter-flow evaporator coil 3 structure, allowing the heat exchange tubes of the evaporator coil 3 to be set in an angled structure. This improves heat exchange efficiency and allows the condensate or cooling medium to be quickly discharged under gravity under condensation and anti-freeze conditions.

[0038] A spike device 7 is installed in the inner cavity of the housing 1 near the side wall of the housing 1. A spike louver 10 is installed on the side wall of the housing 1 near the spike device 7. A second chamber 102 is formed in the inner cavity of the housing 1. The second chamber 102 is located in the outer area of ​​the installation chamber 106, that is, the second chamber 102 is located in the area between the spike device 7 and the support plate 18. Air entering the inner cavity of the housing 1 from the spike louver 10 can enter the second chamber 102 after passing through the spike device 7. Air entering the first chamber 101 from the antifreeze louver 11 can pass through the evaporator coil 3 to achieve the purpose of dual air intake. In addition, in the defogging mode, outside air can enter the cold air channel of the diamond-shaped defogging filler 6 through the peak device 7 and the second chamber 102 to participate in heat exchange. This allows the airflow channel formed by the peak device 7 and the second chamber 102 to be shared in both peak mode and defogging operation mode. There is no need to install an additional independent air supply louver on the equipment, which simplifies the equipment structure, reduces manufacturing costs, and reduces the risk of air leakage.

[0039] At least one diamond-shaped anti-fogging filler 6 is installed inside the housing 1 and above the evaporator coil 3. Air flowing from bottom to top through the installation chamber 106 and air flowing through the second chamber 102 can pass through the diamond-shaped anti-fogging filler 6 and eventually be discharged to the outside of the housing 1.

[0040] In this example, there are two rhomboid anti-fogging fillers 6. The two rhomboid anti-fogging fillers 6 are located above the outside of the installation chamber 106. A drag-reducing louver 5 is installed between the two rhomboid anti-fogging fillers 6. A third chamber 103 is connected above the installation chamber 106. The third chamber 103 is located in the area enclosed by the two rhomboid anti-fogging fillers 6 and the drag-reducing louver 5. The hot air passage of the two rhomboid anti-fogging fillers 6 is connected to the third chamber 103, and the cold air passage of the two rhomboid anti-fogging fillers 6 is connected to the second chamber 102.

[0041] The inner cavity of the housing 1 and above the diamond-shaped anti-fogging filler 6 is formed with a mixing chamber 4. The hot air channel and cold air channel of the diamond-shaped anti-fogging filler 6 are connected to the mixing chamber 4. An exhaust fan 2 is installed on the top of the housing 1. The exhaust fan draws outside air into the housing 1 through the peak louvers 10 and / or the anti-freeze louvers 11, and finally into the mixing chamber 4 before being discharged outward.

[0042] The system also includes a hot water tank 13 and a cold water tank 14 located at the bottom of the housing 1. The hot water tank 13 is used to collect hot water flowing back from the evaporator coil 3, and the cold water tank 14 is used to collect cold water flowing back from the peaking device 7. It also includes an evaporator coil spraying device 9 and a peaking spraying device 8. The evaporator coil spraying device 9 is used to transport and spray cold water from the cold water tank 14 onto the evaporator coil 3, and the peaking spraying device 8 is used to transport and spray hot water from the hot water tank 13 onto the peaking device 7. The evaporator coil spraying device 9 and the peaking spraying device 8 each include a water pump, pipes, and nozzles. The nozzles are connected to the pipes and are positioned above the evaporator coil 3 and the peaking device 7 to achieve a spraying effect. The hot water tank 13 is located near the center of the bottom of the housing 1, the cold water tank 14 is located at the bottom of the housing 1, and a guide pipe 12 is provided below the peaking device 7. The guide pipe 12 is configured to guide the cold water flowing back from the peaking device 7 to the cold water tank 14.

[0043] A water collector is installed in the installation chamber 106 and above the evaporator coil 3. The water collector is mainly used to intercept the liquid water vapor that rises with the airflow. The intercepted water then flows back to the hot water pool 13, which achieves the effect of water saving.

[0044] It also includes a fourth chamber 104, which is formed in the area between the peak device 7 and the cold water pool 14, and the fourth chamber 104 is connected to the first chamber 101. This arrangement is because the guide pipe 12 is located in the fourth chamber 104, and the fresh air entering the box 1 from the outside can exchange heat with the water in the guide pipe 12, thereby further reducing the water temperature in the guide pipe 12.

[0045] Regarding principles and operating modes:

[0046] Now combined Figure 1The peak operation mode of the present invention is described as follows: In peak mode, the antifreeze louvers 11, peak louvers 10, and drag-reducing louvers 5 are all open. Under the action of the induced draft fan 2, the fresh air is divided into two paths. One path enters the fourth chamber 104, the first chamber 101, and the evaporator coil 3 sequentially through the antifreeze louvers 11, where it exchanges heat with the evaporator coil 3. The humid air after heat exchange enters the mixing chamber 4 through the hot air passage of the drag-reducing louvers 5 and the diamond-shaped anti-fog packing 6 from the third chamber 103. The other path of fresh air enters the peak device 7 through the peak louvers 10 and exchanges heat with the spray water. The humid air after heat exchange enters the mixing chamber 4 through the cold air passage of the second chamber 102 and the diamond-shaped anti-fog packing 6, and is finally discharged into the atmosphere by the induced draft fan 2. The spray water undergoes heat exchange with the evaporator coil 3, causing its temperature to rise. Under the influence of gravity, it falls into the hot water tank 13. The peak spray device 8 transports the hot water in the hot water tank 13 to the peak device 7. The spray water, after being cooled by the peak device 7, is transported to the cold water tank 14 by the guide pipe 12. The evaporator coil spray device 9 transports the cold water in the cold water tank 14 to the evaporator coil 3 for heat exchange, and so on.

[0047] Now combined Figure 2 The energy-saving operation mode of the present invention is explained as follows: When the ambient temperature is low and peak operation is not required, the energy-saving mode is executed. The anti-freeze louvers 11 and the drag-reducing louvers 5 are opened, and the peak operation louvers 10 are closed. Under the action of the induced draft fan 2, fresh air enters the fourth chamber 104, the first chamber 101, and the evaporator coil 3 through the anti-freeze louvers 11 in sequence, and exchanges heat with the evaporator coil 3. The humid and hot air after heat exchange enters the mixing chamber 4 through the hot air channels of the drag-reducing louvers 5 and the diamond-shaped anti-fog packing 6, and is finally discharged into the atmosphere by the induced draft fan 2. Due to the opening of the drag-reducing louvers 5, the pressure of the whole equipment is reduced and the operating energy consumption is low. Peak spray device 7 and peak spray device 8 are in a stopped state. The spray water undergoes indirect heat exchange with the evaporator coil 3, causing its temperature to rise. Under the influence of gravity, it falls into the hot water tank 13. The side plate of the hot water tank 13 is lower than that of the cold water tank 14, or an overflow pipe is installed. The spray water after heat exchange overflows from the hot water tank 13 to the cold water tank 14. The evaporator coil spray device 9 transports the spray water from the cold water tank 14 to the evaporator coil 3 for indirect heat exchange, and this cycle continues. Since peak spray device 7 is in a stopped state, the evaporation rate of peak spray device 7 is reduced to zero, making the equipment more water-efficient.

[0048] Now combined Figure 3The defogging operation mode of the present invention is described as follows: When the ambient temperature further decreases, and the humid and hot air at the outlet of the induced draft fan 2 mixes with the low-temperature ambient air to form white fog, the defogging mode is executed. The antifreeze louvers 11 and the peak louvers 10 are opened, while the drag-reducing louvers 5 are closed. Under the action of the induced draft fan 2, the fresh air is divided into two paths, which enter the fourth chamber 104, the first chamber 101, and the evaporator coil 3 sequentially through the antifreeze louvers 11, respectively, and exchange heat with the evaporator coil 3. The humid and hot air after heat exchange passes through the third chamber 103. The hot air from the rhomboid anti-fogging packing 6 enters the mixing chamber 4 through the hot air channel, while another stream of fresh air enters the peak device 7 through the peak louver 10. At this time, the peak device 7 is still in a non-operational state, serving only as a channel for introducing fresh air. The fresh air passes through the peak device 7 and the second chamber 102 into the cold air channel of the rhomboid anti-fogging packing 6. The fresh air and the humid heat from the outlet of the evaporator coil 3 undergo heat exchange through the rhomboid anti-fogging packing 6. The humid hot air in the hot air channel is condensed, and condensate is released. The condensate falls back to the evaporator coil 3 for heat exchange again and is reused. The humid hot air that has undergone heat exchange through the rhomboid anti-fogging packing 6 and the fresh cold air are mixed in the mixing chamber 4 under the action of the induced draft fan 2. Compared with the original nearly saturated humid hot air at the outlet of the evaporator coil 3, the mixed humid air has a lower moisture content, lower relative humidity, and lower temperature, moving away from the 100% relative humidity line. It is then discharged into the atmosphere to come into contact with the low-temperature ambient air, making it less likely to produce white fog.

[0049] Now combined Figure 4 The antifreeze mode of the present invention is explained as follows: When the ambient temperature drops further and the heat exchange equipment is no longer needed to cool the medium, the antifreeze mode is executed. At this time, the antifreeze louvers 11, the drag-reducing louvers 5, and the peak louvers 10 are all closed, and the induced draft fan 2, the peak spray device 8, and the evaporator coil spray device 9 are all stopped. Since all the louvers are closed, the induced draft fan 2 will not generate suction, and the medium in the evaporator coil 3 retains heat, forming a natural warm room inside the equipment, which is beneficial for the equipment to prevent freezing.

[0050] Example 2

[0051] like Figure 5 As shown, the difference between this embodiment and the first embodiment above is that: in this embodiment, there are four diamond-shaped anti-fogging fillers 6, which are connected in sequence and each has a flow divider 17 at its lower end. The four flow dividers 17 divide the space above the installation chamber 106 into an outer third chamber 103 and a middle fifth chamber 105. Both the third chamber 103 and the fifth chamber 105 are connected to the installation chamber 106 where the evaporator coil 3 is located. An airflow distribution louver 15 is installed at the lower end of the fifth chamber 105, and a makeup air louver 16 is installed on the side wall of the housing 1 where the fifth chamber 105 is located. The cold air channels of the two diamond-shaped anti-fogging fillers 6 located on both sides are connected to the second chamber 102.

[0052] In peak mode, the airflow distribution louvers 15 are open and the makeup air louvers 16 are closed. The hot and humid air from the outlet of the evaporator coil 3 passes through the third chamber 103 and the fifth chamber 105, and then enters the mixing chamber 4 through the diamond-shaped defogging packing 6. In defogging mode, the airflow distribution louvers 15 are closed and the makeup air louvers 16 are open. The hot and humid air from the outlet of the evaporator coil 3 is blocked by the airflow distribution louvers 15 and enters the hot air passage of the third chamber 103 and the diamond-shaped defogging packing 6. One path of fresh air enters the cold air passage of the diamond-shaped defogging packing 6 through the peak louvers 10, the peak device 7, and the second chamber 102. Another path of fresh air enters the fifth chamber 105 through the makeup air louvers 16 and then enters the cold air passage of the diamond-shaped defogging packing 6. The fresh air and the hot and humid air from the outlet of the evaporator coil 3 undergo heat exchange at the indirect wall of the diamond-shaped defogging packing 6.

[0053] In this embodiment and Embodiment 1, the rhomboid anti-fogging filler 6 is arranged symmetrically with respect to the central axis of the housing 1, and the number of each filler is an even number, for example, 4 in this embodiment and 2 in Embodiment 1. As the size of the housing 1 increases, the number of rhomboid anti-fogging filler 6 can be increased accordingly, for example, to 6, 8, 10 or more.

[0054] It is also understood that in other embodiments, the rhomboid anti-fogging filler 6 may also be arranged in an asymmetrical manner relative to the central axis of the housing 1, and the number of them may be an odd number, such as 1, 3, 5, 7, etc.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
