Description

Technical Field

[0001] This utility model belongs to the field of co-current evaporative cooling technology, specifically relating to a co-current integrated evaporative cooling unit. Background Technology

[0002] In the field of industrial refrigeration, evaporative condensers, as key heat exchange equipment, are widely used in process cooling systems in industries such as chemical, petroleum, and pharmaceutical. Traditional co-flow evaporative condensers generally adopt a split structure, consisting of an independent upper casing (containing a fan and spray system) and a lower casing (containing heat exchange tube assemblies and a water collection tank). This split design leads to the following significant drawbacks:

[0003] 1. Structural redundancy: The split structure requires an additional bottom support frame, which not only increases material costs but also causes the overall height of the equipment to exceed the standard, making it difficult to meet the size restrictions of container shipping.

[0004] 2. Difficult to maintain: Traditional water collection tanks use a closed welded frame. When the internal heat exchange modules are scaled or damaged, they must be completely disassembled and repaired, resulting in high maintenance costs and long downtime.

[0005] 3. Energy efficiency bottleneck: Existing equipment mostly uses high-power single fan configuration, which cannot meet the first and second level energy efficiency requirements of the new national standard. In addition, the PVC material air inlet structure has low strength and is easy to deform, which leads to air duct leakage and reduces heat exchange efficiency.

[0006] 4. Insufficient water conservation: Conventional sprinkler systems have poor water droplet distribution uniformity, with some areas having blind spots, resulting in water waste.

[0007] To address the aforementioned issues, the industry urgently needs a highly integrated, easy-to-maintain evaporative cooling system that meets energy and water conservation requirements. Although some improvement solutions have proposed modular designs, problems such as loose structure and poor maintainability still exist, failing to effectively solve the fundamental defects of the split structure. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a co-current integrated evaporative cooler, which solves the problems mentioned in the background technology.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a co-current integrated evaporative cooler, comprising: a static pressure air box, a heat exchange tube assembly disposed beside the static pressure air box, a spray tube assembly located above the heat exchange tube assembly, and a water collection tank connected to the spray tube assembly via a circulating water pump. The water collection tank integrates a high-efficiency heat exchange module, a water collector is provided at the bottom of the static pressure air box, and an integrated air inlet is configured at the front end of the equipment. The spray water from the spray tube assembly is cooled by the high-efficiency heat exchange module and returns to the water collection tank, forming a spray water circulation path via the circulating water pump. The height of the static pressure air box is flush with the spray tube assembly, and the air inlet is made of aluminum-zinc coated panel or stainless steel, with a thickness consistent with the outer steel plate of the integrated unit.

[0010] Preferably, the water collection tank eliminates the bottom frame and adopts a detachable panel splicing structure.

[0011] Preferably, the air inlet is an integral, detachable structure that is bolted to the integrated frame, serving both as a support and a wind direction guide.

[0012] Preferably, the front and rear side panels of the all-in-one machine have an integral sealed structure to prevent water leakage.

[0013] Preferably, the water collection tank is equipped with an inspection passage and an inspection door for internal equipment maintenance.

[0014] Preferably, a plurality of three-splash nozzles are evenly distributed at the bottom of the spray pipe assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By adopting an integrated structural design of half coil and half packing, the upper and lower boxes and supporting components of the traditional split evaporative cooler are integrated into a single unit, effectively eliminating the bottom frame structure and reducing the number of parts, thus significantly reducing equipment manufacturing costs. The panel-mounted water tank design, combined with the detachable panel structure, allows for the inspection and maintenance of the high-efficiency heat exchange module without disassembling the entire unit, greatly improving equipment maintainability.

[0017] 2. The overall structure is designed according to standard container dimensions. While ensuring a reasonable layout of internal functional components, the external dimensions of the equipment are minimized to meet the container loading requirements of overseas transportation and save on-site installation space. By configuring multiple small-diameter fans and using replaceable energy-efficient motors, the equipment's energy consumption meets the new national standard's Level 1 or Level 2 energy efficiency standards, while also reducing operating noise.

[0018] 3. The integrated air inlet structure made of aluminized zinc plate improves its resistance to deformation while achieving rigid coordination with the equipment shell through thickness matching. This ensures precise control of the air inlet angle and enhances the overall structural stability. The optimized design of the static pressure box height, combined with the fluid guiding structure of the water collector support plate, reduces airflow resistance and improves heat exchange efficiency.

[0019] 4. The spray pipe assembly uses a three-splash nozzle to achieve uniform water distribution, combined with a dual cooling mechanism of a high-efficiency heat exchange module, significantly improving water resource utilization. The front and rear integral sealed panel structure completely eliminates the leakage risk of traditional spliced ​​enclosures, ensuring the long-term reliability of the equipment.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. 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.

[0024] The following reference Figures 1-2 This application describes an embodiment of a co-current integrated evaporative cooler.

[0025] An integrated evaporative air cooler includes: a static pressure box 1, a heat exchange tube assembly 2 located beside the static pressure box 1, a spray tube assembly 3 located above the heat exchange tube assembly 2, and a water collection tank 5 connected to the spray tube assembly 3 via a circulating water pump 4. The water collection tank 5 integrates a high-efficiency heat exchange module 6. The static pressure box 1 is equipped with a water collector 7 at the bottom and an integrated air inlet 8 at the front end of the equipment. The spray water from the spray tube assembly 3 is cooled by the high-efficiency heat exchange module 6 and returns to the water collection tank 5. The circulating water pump 4 forms a spray water circulation path. The height of the static pressure box 1 is flush with that of the spray tube assembly 3. The air inlet 8 is made of aluminum-zinc coated panel or stainless steel, and its thickness is the same as that of the outer steel plate of the integrated unit.

[0026] Furthermore, the bottom frame of the water collection tank 5 is eliminated, and a detachable panel splicing structure is adopted. After the rear panel is removed, the high-efficiency heat exchange module 6 can be repaired or replaced.

[0027] Furthermore, the angle of the water collector 7 support plate at the bottom of the static pressure air box 1 has been optimized through fluid dynamics calculations, and it has a flow guiding function.

[0028] Furthermore, the air inlet 8 is an integral, detachable structure that is bolted to the integrated frame, serving both as a support and a wind direction guide.

[0029] In a further embodiment, the front and rear side panels of the all-in-one machine have an integral sealed structure to prevent water leakage.

[0030] In a further embodiment, the water collection tank 5 is provided with an inspection passage and an inspection door for internal equipment maintenance.

[0031] In a further embodiment, several three-splash nozzles are evenly distributed at the lower part of the spray pipe assembly 3.

[0032] In a further embodiment, the integrated machine is designed with container dimensions to suit maritime transport.

[0033] The specific working process of a co-current integrated evaporative cooler according to the present application is described in conjunction with the above embodiments: the working process of the integrated cooler revolves around the circulation and coordinated heat dissipation of the refrigerant, spray water, and air, and is implemented as follows:

[0034] 1. Refrigeration medium circulation: The refrigerant enters the serpentine heat exchange tube group 2 from the air inlet 8 and flows in a "top in, bottom out" manner, releasing heat to the tube wall; the heat is transferred to the external spray water film and air through the tube wall to complete the initial cooling.

[0035] 2. Spray water circulation: The circulating water pump 4 pumps the cooling water in the water collection tank 5 to the spray pipe assembly 3, and sprays it evenly onto the surface of the heat exchange pipe assembly 2 through the lower three-splash nozzle to form a water film. After evaporation and heat absorption, the water flows through the high-efficiency heat exchange module 6 for further cooling, and finally falls back to the water collection tank 5 for recycling.

[0036] 3. Airflow and heat dissipation: External air enters at a set angle through the integrated air inlet 8 (aluminized zinc / stainless steel material), passes through the high-efficiency heat exchange module 6 to absorb the heat generated by the evaporation of the water film, and then passes through the water collector 7 to remove water droplets before being drawn out by the fan in the static pressure air box 1. The height of the static pressure air box 1 is flush with the spray pipe assembly 3, which reduces wind resistance and increases wind speed, thereby enhancing heat exchange.

[0037] 4. Structural optimization and maintenance:

[0038] Frameless design: The bottom frame of the water collection tank 5 is eliminated, and a detachable panel is used for splicing. During maintenance, the panel can be removed to pull out the high-efficiency heat exchange module 6 for cleaning scale.

[0039] Maintenance access: A maintenance access is provided inside the water collection tank 5, through which maintenance personnel can enter to handle faults.

[0040] Static pressure box optimization: The lower water collector 7 support plate is designed with a flow guiding angle to reduce wind resistance and guide airflow.

[0041] Compact design: The overall design is based on the size of a shipping container, saving space and facilitating transportation, thus meeting the needs of overseas markets.

[0042] 5. Key collaborative components:

[0043] The air inlet 8 has both airflow guiding and support functions, and is made of sturdy and durable material;

[0044] The high-efficiency heat exchange module 6 achieves dual cooling of water and air;

[0045] The static pressure fan box 1 improves heat dissipation efficiency by reducing its height and using a flow-guiding design.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
