Description

Technical Field

[0001] This utility model relates to the field of tube bundle spraying technology, and more specifically, to an air-cooled tube bundle spraying device. Background Technology

[0002] Air-cooled tube bundles are important heat dissipation components, playing a crucial role in many fields. For example, air-cooled tube bundles mainly come in two shapes: straight tubes and bent tubes. Straight tubes have a relatively simple structure, providing direct and efficient heat dissipation, suitable for concentrated heat sources and single heat dissipation spaces. Bent tubes, on the other hand, have a more complex but flexible structure, adapting to different application environments through bending, improving space utilization efficiency, and are suitable for complex applications and confined heat dissipation spaces. Therefore, high-efficiency spray cooling is required during heat dissipation.

[0003] Most common spray devices have poor spray pressure during operation, resulting in low efficiency in heat dissipation and cooling. Furthermore, when the pump is stopped after cooling is complete, the tube bundle is easily damaged, internal components are destroyed, the lifespan of the device is reduced, and maintenance costs are increased.

[0004] For example, Chinese patent CN211503764U discloses an automatic spray cooling device for air cooler tube bundles, including a self-controlled water pump and a controller. The controller receives temperature signals from a remote thermometer in real time and can send control signals to control the start and stop of the self-controlled water pump. The remote thermometer is installed on the outlet pipe of the air cooler. Although this device is equipped with valves and a pump to control the water flow, it does not provide protection or buffering for the pipes when shutting down, which may cause damage to the pipes. Furthermore, although multiple nozzles are installed for cooling, the cooling and heat dissipation are not uniform, resulting in poor cooling efficiency.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an air-cooled tube bundle spray device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] An air-cooled tube bundle spraying device includes a water storage tank, a water pump at one end of the water storage tank, a first delivery pipe at the top of the water pump, a solenoid valve at the top of the first delivery pipe, a second delivery pipe connected to the top of the solenoid valve, a buffer mechanism at the top of the second delivery pipe, and a third delivery pipe at the top of the buffer mechanism. The third delivery pipe has an L-shaped structure and a plurality of linearly arranged nozzle assemblies at the top of the third delivery pipe. The two ends of the solenoid valve are connected to the first and second delivery pipes, respectively.

[0009] Furthermore, to alleviate pressure when the water source is shut off, extend pipeline life, and reduce maintenance costs, the buffer mechanism includes a rhomboid shell positioned at the top of the second conveying pipeline. Inside the rhomboid shell is a fixed plate with several evenly spaced water passages. A chuck is located at the bottom of the fixed plate. A movable column is positioned in the center of the fixed plate, with a buffer plate at its bottom. A central spur is located at the bottom of the buffer plate, and a buffer spring is positioned on the outer circumference of the central spur. The central spur and the buffer spring pass through a fixed rod positioned between the inner wall of the second conveying pipeline and extend below the fixed rod. Symmetrically arranged locking blocks are positioned on the outer circumference of the fixed plate, engaging with slots symmetrically positioned on both sides of the rhomboid shell, and the buffer plate also engages with the chuck. An arc-shaped buffer groove is formed inside the rhomboid shell.

[0010] Furthermore, to increase the water pressure and improve the delivery and heat dissipation efficiency of the nozzle, the nozzle assembly includes a contraction tube extending through one end of the third delivery pipe. A narrow throat is located at the top of the contraction tube, and an expansion tube is located at the top of the narrow throat. A spray head is located inside the top of the expansion tube. The diameter of the narrow throat is smaller than the diameters of the contraction and expansion tubes.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. When the water tank delivers water into the delivery pipe, the nozzles spray the pipe bundle to cool it down. By setting up a buffer mechanism and nozzle assembly, when the water from the water tank enters the delivery pipe, the nozzle assembly increases the pressure of the water source during water delivery, improving the delivery and heat dissipation efficiency of the nozzles. After heat dissipation, the water pump stops, and the buffer mechanism reduces the pressure on the pipe, relieving the pressure when the water source is shut off, thus increasing the lifespan of the pipe and reducing maintenance costs.

[0013] 2. By setting the nozzle assembly, the diameter of the contraction tube and expansion tube at the bottom of the spray head is larger than the diameter of the narrow throat tube. When the water source is delivered, the water source first passes through the contraction tube to the narrow throat tube for compression, which increases the power of the water source spray. Then, the water source with the power passes through the narrow throat tube to the expansion tube and is sprayed to the spray head, which improves the spray efficiency and power.

[0014] 3. By setting up a buffer mechanism, after the spray cooling and heat dissipation, when shutting down, the water power generated is used in conjunction with the buffer plate, arc-shaped buffer groove and water passage hole to buffer the water power and slowly shut off, thereby improving the impact of the power water source and increasing the service life of the pipeline.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, an air-cooled tube bundle spray device is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, an air-cooled tube bundle spraying device according to an embodiment of the present invention includes a water storage tank 1, a water pump 2 is provided at one end of the water storage tank 1, a first conveying pipe 3 is provided at the top of the water pump 2, a solenoid valve 4 is provided at the top of the first conveying pipe 3, a second conveying pipe 5 is connected to the top of the solenoid valve 4, a buffer mechanism 6 is provided at the top of the second conveying pipe 5, a third conveying pipe 7 is provided at the top of the buffer mechanism 6, the third conveying pipe 7 has an L-shaped structure, and a plurality of nozzle assemblies 8 arranged linearly are provided at the top of the third conveying pipe 7.

[0026] With the help of the above-mentioned technical solution of this utility model, when the water storage tank 1 is transported into the conveying pipe to transport water, the nozzle is used to spray and cool the pipe bundle; by setting the buffer mechanism 6 and the nozzle assembly 8, when the water source of the water storage tank 1 enters the conveying pipe, the nozzle assembly 8 increases the pressure of the water source when transporting water, thereby improving the conveying efficiency and heat dissipation efficiency of the nozzle. After heat dissipation, the water pump is stopped, and the buffer mechanism 6 is used to reduce the pressure on the pipe, thereby relieving the pressure when the water source is turned off, improving the life of the pipe, and reducing maintenance costs.

[0027] In one embodiment, the buffer mechanism 6 includes a rhomboid shell 601 disposed at the top of the second conveying pipe 5. A fixed plate 602 is disposed inside the rhomboid shell 601, and several water passage holes 603 are evenly distributed on the fixed plate 602. A chuck 604 is disposed at the bottom of the fixed plate 602. A movable column 605 is disposed in the middle of the fixed plate 602, and a buffer plate 606 is disposed at the bottom of the movable column 605. A central hub 607 is disposed at the bottom of the buffer plate 606, and a buffer spring 608 is disposed on the outer circumference of the central hub 607. The central hub 607 and the buffer spring 608 pass through a fixed rod 609 disposed between the inner wall of the second conveying pipe 5 and extend below the fixed rod 609. A locking block 610 is symmetrically disposed on the outer circumference of the fixed plate 602. The locking block 610 cooperates with a locking groove 611 symmetrically disposed on both sides inside the rhomboid shell 601, and the buffer plate 606 cooperates with the chuck 604. The rhomboid shell 601 has an arc-shaped buffer groove 6011 inside, which relieves the pressure when the water source is shut off, increases the life of the pipeline, and reduces maintenance costs.

[0028] The working principle of the buffer mechanism 6 is as follows: First, the locking block 610 of the fixed plate 602 is fixedly engaged with the locking groove 611 of the rhomboid shell 601. When the water source is turned on, the impact force of the water pushes the buffer plate 606 to move backward, and the central hub 607 and the buffer spring 608 are compressed backward by the fixed rod 609 under the push of the power. The movable column 605 moves backward in the middle of the fixed plate 602. Then, the water source is transported to the conveying pipe through the water passage 603 and the arc-shaped buffer groove 6011. When the water source is turned off, the remaining water impact force moves the buffer plate 606 forward, and the buffer plate 606 is closed and locked with the locking plate 604.

[0029] In one embodiment, the nozzle assembly 8 includes a converging tube 801 extending through one end of the third delivery pipe 7. A narrow throat 802 is located at the top of the converging tube 801, and an expanding tube 803 is located at the top of the narrow throat 802. A spray head 804 is located inside the top of the expanding tube 803. The converging tube 801 and the expanding tube 803 have the same structure, and the diameter of the narrow throat 802 is smaller than the diameters of both the converging tube 801 and the expanding tube 803, thereby increasing the water pressure and improving the delivery and heat dissipation efficiency of the nozzle.

[0030] The working principle of the nozzle assembly 8: When the water source reaches the contraction tube 801 through the third delivery pipe 7, the water source is compressed. The cross-sectional area of ​​the pipe gradually decreases, and the spray speed increases. Then, it is compressed again through the narrow throat 802. The flow rate of the water source reaches the critical state. Finally, it is released into the spray head 804 through the expansion tube 803. The flow rate of the water source is further accelerated and enters the spray head 804 for a large amount of spraying. The diameter of the narrow throat 802 is smaller than the diameter of the contraction tube 801 and the expansion tube 803. The diameter of the contraction tube 801 at the inlet is larger than that of the narrow throat 802, but gradually decreases to the diameter of the narrow throat 802.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical applications, when the water storage tank 1 uses the water pump 2 to transport water through the first transport pipe 3, the second transport pipe 5, and the third transport pipe, the solenoid valve 4 controls the amount of water being transported. During transport, the nozzle assembly 8 is used to increase the power of the spray (the working principle of the nozzle assembly 8 is as described above), thereby increasing the spray area. After heat dissipation, the water source is shut off. In the second transport pipe 5, the buffer mechanism 6 is used to buffer the impact force of the water source (the working principle of the buffer mechanism 6 is as described above).

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, when the water storage tank 1 delivers water into the delivery pipe, the spray head 804 sprays water onto the pipe bundle to cool and dissipate heat. By setting up the buffer mechanism 6 and the nozzle assembly 8, when the water source from the water storage tank 1 enters the delivery pipe, the nozzle assembly 8 increases the pressure of the water source during water delivery, thereby improving the delivery efficiency and heat dissipation efficiency of the spray head 804. After heat dissipation, the water pump 2 is stopped, and the buffer mechanism 6 reduces the pressure on the pipe, alleviating the pressure when the water source is shut off, thus improving the lifespan of the pipe and reducing maintenance costs. By setting up the nozzle assembly 8, the diameter of the contraction tube 801 and the expansion tube 803 at the bottom of the spray head 804 is larger than the diameter of the narrow throat tube 802. During water delivery, the water source first passes through the contraction tube 801 to the narrow throat tube 802 for compression, increasing the spray power of the water source. Then, the water source, powered by the narrow throat tube 802, passes through the expansion tube to the spray head 804 for spraying, improving the spray efficiency and power. By setting up a buffer mechanism 6, after spray cooling and heat dissipation, when closing, the water source power is generated. With the cooperation of the buffer plate 606, the arc-shaped buffer groove 6011, and the water passage hole 603, the power of the water is buffered and then slowly closed, which improves the impact of the power water source and increases the service life of the pipeline.
