Description

Technical Field

[0001] This utility model belongs to the technical field of evaporative condensers, specifically relating to an enhanced evaporative condenser. Background Technology

[0002] Traditional evaporative condensers typically employ an integrated design, combining the fan, coil assembly, spray system, and water tank within a single housing. This monolithic structure has significant drawbacks in practical applications: 1. Poor maintenance continuity: When coil leaks or become clogged, the entire unit must be shut down for repair, severely impacting industrial production continuity and reducing efficiency. 2. High equipment replacement costs: Due to the strong coupling between components, upgrades require complete equipment replacement, rendering the residual value of older parts unusable. Especially when addressing the need for replacement with new environmentally friendly refrigerants, traditional structures struggle to achieve gradual upgrades. 3. Limited transportation and installation: The large size of monolithic condensers necessitates special permits for road transport, and on-site installation requires large lifting equipment. Existing modular solutions are mostly limited to separate fan and main unit designs, leaving the core heat exchange unit indivisible.

[0003] While recent modular designs (e.g., patent application CN214095046U) have made the condenser section independent, the coil system still uses a welded, fixed structure, and partial damage to a coil unit still requires replacement of the entire unit. More importantly, existing evaporative condensers generally use a centralized spray design for their water circuits. When a single coil unit fails, the entire spray system must stop operating, reducing efficiency. Although some designs propose zoned control valve schemes, their piping layout results in insufficient space for valve operation, requiring shutdown and pressure relief for actual maintenance. Therefore, this invention proposes an efficiency-enhancing evaporative condenser that improves heat exchange efficiency while meeting the core requirements of rapid isolation of faulty units without shutdown, compatibility between new and old modules, and convenient transportation. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an efficiency-enhancing evaporative condenser, comprising a fan module, a water tank module, and a coil module. The coil module is composed of at least one detachably connected coil module. Each of the fan module, water tank module, and coil module includes a housing. The housing ports of the fan module, water tank module, and coil module are all fastened together by bolts. A serpentine coil is installed inside the housing of the coil module. A spray pipe parallel to the serpentine coil is installed on the top of the serpentine coil. Spray nozzles are evenly installed on the body of the spray pipe. The inlet and outlet of the serpentine coil and the inlet of the spray pipe extend to the outside of the housing of the coil module. The inlet and outlet of adjacent serpentine coils and the inlet of the spray pipe are connected to a branch pipe by a flange.

[0005] As a preferred embodiment of this utility model, a fan body is installed on the top of the fan module housing, and a dehydration plate is fixed inside the fan module housing.

[0006] As a preferred embodiment of this utility model, a first control valve is installed at the inlet and outlet of the serpentine coil and at the connection of the corresponding diversion pipe, and a second control valve is installed at the inlet of the spray pipe and at the connection of the corresponding diversion pipe.

[0007] As a preferred technical solution of this utility model, the inlet of the diversion pipe connected to the spray pipe inlet is connected to the bottom of the housing of the water tank module, and a delivery pump is installed on the pipe body at the inlet of the diversion pipe connected to the spray pipe inlet.

[0008] As a preferred embodiment of this utility model, louvered windows are fixed on both sides of the housing of the water tank module.

[0009] As a preferred technical solution of this utility model, the serpentine coil body is uniformly welded with heat dissipation fins.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) This utility model not only avoids production losses caused by overall shutdown through the rapid isolation function of fault units, but also reduces unnecessary maintenance workload. Maintenance personnel only need to repair or replace the faulty coil module, without the need for large-scale disassembly and debugging of the entire condenser system; and can keep other modules running normally when some modules fail, reducing the number of equipment start-ups and shutdowns, thereby effectively extending the service life of the fan module, water tank module and the entire condenser system, and improving heat exchange efficiency; at the same time, each coil module is independently equipped with a spray pipe, which optimizes the heat exchange process in all aspects, reduces the decrease in heat exchange efficiency caused by spray system failure, significantly improves the overall heat exchange efficiency, and achieves the purpose of efficiency enhancement and stable operation.

[0012] (2) The progressive upgrade feature of this utility model enables enterprises to gradually optimize the equipment over a longer period of time according to their own needs and market technology development, thus maintaining the equipment's advanced nature. Simultaneously, the modular design facilitates transportation and on-site installation, significantly shortening transportation time and installation / commissioning cycles during industrial project construction; and eliminates the need for large lifting equipment for on-site hoisting, reducing safety risks caused by improper operation of large equipment. Furthermore, the simplified installation process lowers the requirements for the professional skills of installation personnel, further reducing the risk of equipment damage or substandard installation due to human error during installation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figures 1-4 The present invention provides the following technical solution: an efficiency-enhancing evaporative condenser, comprising a fan module, a water tank module, and a coil module. The coil module consists of at least one detachably connected coil module. The fan module, water tank module, and coil module all include a housing 1. The ports of the housing 1 of the fan module, water tank module, and coil module are all fastened together by bolts. A serpentine coil 2 is installed inside the housing 1 of the coil module. A spray pipe 3 parallel to the serpentine coil 2 is installed on the top of the serpentine coil 2. Spray nozzles 4 are evenly installed on the body of the spray pipe 3. The inlet and outlet of the serpentine coil 2 and the inlet of the spray pipe 3 extend to the outside of the housing 1 of the coil module. The inlet and outlet of the adjacent serpentine coil 2 and the inlet of the spray pipe 3 are all connected by a branch pipe 5 through a flange.

[0022] In order to enhance the heat exchange effect between air and water film and effectively recover water droplets that escape with the airflow, thereby reducing water waste and impact on the surrounding environment, in this embodiment, as a preferred technical solution of the present invention, a fan body 6 is installed on the top of the housing 1 of the fan module, and a dehydration plate 7 is fixed inside the housing 1 of the fan module.

[0023] In order to quickly and independently cut off the medium flow of the corresponding module when some coil modules or spray pipes 3 fail, realize the rapid isolation of the faulty unit, ensure the normal operation of other parts of the condenser, and improve the convenience and efficiency of operation and maintenance, in this embodiment, as a preferred technical solution of the present invention, a first control valve 8 is installed at the connection between the inlet and outlet of the serpentine coil 2 and the corresponding branch pipe 5, and a second control valve 9 is installed at the connection between the inlet of the spray pipe 3 and the corresponding branch pipe 5.

[0024] In order to provide a stable and pressurized water flow to the spray pipe 3, and to ensure that the cooling water can be sprayed evenly and efficiently on the surface of the serpentine coil 2 to maintain good heat exchange conditions, in this embodiment, as a preferred technical solution of the present invention, the inlet of the spray pipe 3 is connected to the bottom of the housing 1 of the water tank module, and a delivery pump 10 is installed on the pipe body at the inlet of the branch pipe 5 connected to the inlet of the spray pipe 3.

[0025] In order to adjust the ventilation inside the water tank module, optimize the heat dissipation environment of the cooling water inside the water tank, maintain a suitable temperature of the cooling water, and thus improve the heat exchange efficiency of the entire condenser, in this embodiment, as a preferred technical solution of the present invention, louvered windows 11 are fixed on both sides of the housing 1 of the water tank module.

[0026] In order to increase the contact area between the serpentine coil 2 and the surrounding air and spray water film, enhance the heat transfer process, significantly improve the heat exchange performance of the condenser, and meet the demand for efficient heat dissipation in industrial production, in this embodiment, as a preferred technical solution of the present invention, heat dissipation fins 12 are uniformly welded to the body of the serpentine coil 2.

[0027] In this embodiment, the dehydration plate 7 is a known technology that is widely used in daily life. Through its unique wave-like design, it increases the contact area and path length between the gas and the dehydration plate 7. A series of grooves and protrusions are formed between adjacent corrugations. This structure guides the airflow to generate complex turbulence as it passes through, causing water droplets mixed in the airflow to impact the surface of the corrugated plate due to inertia. The heavier water droplets slide down the surface of the dehydration plate 7 under the action of gravity and flow back to the water collection area of ​​the condenser.

[0028] In summary, with the help of the above-described technical solution of this utility model,

[0029] Overall heat exchange process: The high-temperature gaseous working fluid generated in industrial production is diverted through the diversion pipe 5 at the inlet end of the serpentine coil 2 and then enters the serpentine coil 2 in the coil module. At the same time, the cooling water in the water tank module, under the action of the delivery pump 10, flows from the bottom of the water tank module shell 1 through the corresponding diversion pipe 5 into the corresponding spray pipe 3. The spray nozzles 4 evenly distributed on the body of the spray pipe 3 spray the cooling water onto the surface of the serpentine coil 2, forming a water film. Simultaneously, the fan body 6 at the top of the fan module starts, drawing in the surrounding air. The air flows from bottom to top, making full contact with the water film on the surface of the serpentine coil 2. During this process, the cooling water absorbs the heat of the high-temperature gaseous working fluid in the serpentine coil 2 and evaporates, carrying away a large amount of latent heat, causing the gaseous working fluid to condense into a liquid state in the serpentine coil 2, completing the heat exchange process.

[0030] Ease of Operation and Maintenance: The coil module consists of multiple detachably connected coil modules. When a serpentine coil 2 within a coil module experiences a leak, blockage, or other malfunction, the faulty coil module can be quickly isolated by closing the first control valve 8 at the connection point between the inlet / outlet of the serpentine coil 2 and the corresponding branch pipe 5, as well as the second control valve 9 at the connection point between the inlet of the spray pipe 3 and the corresponding branch pipe 5. Other normally functioning coil modules can continue operating without requiring a complete shutdown, greatly improving operational continuity and reducing the impact on industrial production.

[0031] Equipment upgrade flexibility: Since the housings of the fan module, water tank module, and coil module are all bolted together at port 1, each module has good independence. When facing the need for replacement with new environmentally friendly working fluids or equipment upgrades, the corresponding modules can be replaced individually as needed, making full use of the remaining value of old components, reducing equipment replacement costs, and achieving gradual upgrades.

[0032] Convenience of transportation and installation: The modular design reduces the size of each part of the condenser, facilitating road transport without the need for special permits. On-site hoisting also eliminates the need for large lifting equipment, reducing installation difficulty and cost.

[0033] Fan module: The forced airflow generated by the fan body 6 not only promotes the evaporation of water on the surface of the water film and accelerates the heat exchange rate, but also intercepts and recycles water droplets mixed in the air through the dehydration plate 7 fixed inside the fan module housing 1, avoiding water waste and impact on the surrounding environment.

[0034] Water tank module: The louvered windows 11 fixed on both sides of the water tank module can adjust the ventilation volume, ensuring that the cooling water temperature in the water tank is maintained within a suitable range, preventing the water temperature from being too high and affecting the heat exchange efficiency. At the same time, the water tank provides a stable water source for the spray system, ensuring that the spraying process continues.

[0035] Coil Module: The heat dissipation fins 12, evenly welded to the body of the serpentine coil 2, increase the contact area between the coil and the air and water film, enhancing the heat transfer effect. The inlet and outlet of the adjacent serpentine coil 2 and the inlet of the spray pipe 3 are connected through the diversion pipe 5, making the water flow distribution in each coil module more uniform and improving the heat exchange efficiency of the entire coil module.

[0036] Finally, it should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
