Description

Technical Field

[0001] This utility model belongs to the field of heat source tower technology, specifically relating to a noise reduction structure device for a closed heat source tower. Background Technology

[0002] Closed-loop heat source towers are widely used in regional energy stations, large commercial buildings, data centers, and other fields, possessing advantages such as energy efficiency, system cleanliness, safety, environmental protection, and stable operation. The finned heat exchanger is the core heat exchange component inside the closed-loop heat source tower. However, currently, closed-loop heat source towers experience significant vibration during operation, resulting in high noise levels. While noise reduction measures such as noise reduction panels and enclosed spaces are typically used during installation to mitigate noise, the effect is not significant. If installed near residential buildings, it may disturb nearby residents' rest, and the installation structure is complex and inconvenient. Patent CN 10953765 A discloses a non-co-flow V-shaped air-cooled modular unit outer frame, including a frame body, a chassis assembly, a column at each of the four corners of the chassis assembly, a crossbeam connecting the middle of the columns, a heat exchanger base installed between the crossbeams, a surrounding panel between the crossbeams and the chassis assembly, an electrical box installed between the surrounding panels, and a top beam assembly installed on the top of the columns. This invention features a simple structure and small footprint. The two chambers can monitor the temperature of the fins in each system independently via left and right temperature sensors, enabling independent defrosting and allowing for more precise system adjustments, reduced power consumption, and improved energy efficiency. However, the finned heat exchanger in the unit is installed via a triangular fan mounting plate and heat exchanger base. The support column does not provide optimal support and stability, resulting in an unstable installation structure and potential resonance and noise during fan operation. Therefore, there is a need to develop a simple, easy-to-install, closed-loop heat source tower installation device that provides sufficient airflow while offering good vibration and noise reduction. Utility Model Content

[0003] In order to solve the existing technical problems, this utility model provides a closed heat source tower noise reduction structure device to achieve good vibration reduction and noise reduction effect when the air volume is sufficient.

[0004] The technical solution of this utility model is: a closed heat source tower noise reduction structure device, including a finned heat exchanger, a column, a triangular plate, a chassis, a fan installation structure and a fan; the lower end of the finned heat exchanger is fixed to the chassis, the two ends of the inner side of two adjacent finned heat exchangers are connected by a triangular plate, and the outer side is supported by a column, the lower end of the column is fixed to the chassis.

[0005] The triangular plate includes a lower triangular plate, a middle left triangular plate, a middle right triangular plate and an upper triangular plate that are connected to each other. The two sides of the upper triangular plate are connected to the finned heat exchanger through corner stops.

[0006] The fan mounting structure is installed on the upper triangular plate and the upper end of the finned heat exchanger. The fan mounting structure is a grid-shaped structure. A reinforcing plate is set between the fan mounting structure and the upper end of the finned heat exchanger. The fan is installed on the fan mounting structure.

[0007] Furthermore, the finned heat exchanger is installed and fixed in a V-shape, and the relative angle between the two finned heat exchangers is 40°.

[0008] Furthermore, a diagonal brace is provided in the upper middle part of the column, and the lower end of the diagonal brace is fixed to the chassis.

[0009] Furthermore, the fan mounting structure includes a front upper crossbeam, a rear upper crossbeam, a left upper crossbeam, a right upper crossbeam, a middle support beam, and a middle upper crossbeam. The middle support beam is located between the left upper crossbeam and the right upper crossbeam, and the middle upper crossbeam is located between the front upper crossbeam and the rear upper crossbeam. The middle support beam is fixed to the finned heat exchanger by a reinforcing plate. The front upper crossbeam and the rear upper crossbeam are respectively fixed to the upper triangular plate, and the left upper crossbeam and the right upper crossbeam are respectively fixed to the finned heat exchanger.

[0010] Furthermore, the reinforcing plate has a U-shaped structure with the outer end bent downwards, and an upper baffle plate is installed on the upper part of the finned heat exchanger; the inner end of the reinforcing plate is connected to the intermediate support beam, and the outer end of the reinforcing plate is connected to the upper baffle plate of the finned heat exchanger.

[0011] Furthermore, the baffle is a trapezoidal structure, with its inner end face connected to the upper triangular plate and its lower end face connected to the upper end of the finned heat exchanger.

[0012] Furthermore, the triangular plate and the fan mounting structure are designed with ribs.

[0013] Furthermore, louvers are provided at the upper 1 / 3 of the finned heat exchanger.

[0014] Furthermore, the fan is a high-duct, low-noise fan.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] (1) This utility model fixes the finned heat exchanger with columns and triangular plates, and increases the stress points of the finned heat exchanger with baffles and reinforcing plates, making the overall structure more stable. The fan installation structure effectively reduces the resonance generated during the operation of the fan, reduces the noise generated by the vibration due to structural instability, and achieves a good noise reduction effect.

[0017] (2) The triangular plate of this utility model is divided into 4 areas, which avoids the defect that the whole triangular plate is too large and the plate is relatively soft, resulting in a large noise. In addition, the upper triangular plate is connected to the fan installation structure, which reduces the noise caused by the vibration of the fan resonance.

[0018] (3) The fan installation structure of this utility model adopts a grid-shaped structure. There is no need to set up a corresponding noise reduction plate to seal the top of the fan installation structure. After the fan is installed on the fan installation structure, the vibration and noise reduction effect of the fan installation structure can effectively reduce the structural vibration noise caused by the operation of the fan.

[0019] (4) By adding diagonal bracing to the columns, the original linear connection of the columns is changed to a surface connection, which increases the stability of the overall structure and further reduces noise.

[0020] (5) By adding louvers as air guides at the upper 1 / 3 of the finned heat exchanger, the wind speed is stabilized and the noise is further reduced.

[0021] (6) The structure of this utility model is simple and easy to install. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] Reference Figure 1-8 A noise reduction structure device for a closed heat source tower includes a finned heat exchanger 1, a column 2, a triangular plate 3, a chassis 4, a fan mounting structure 5, and a fan 6. The lower end of the finned heat exchanger 1 is fixed to the chassis 4. The two ends of the inner sides of two adjacent finned heat exchangers 1 are connected by the triangular plate 3, and the outer sides are supported by the column 2. The lower end of the column 2 is fixed to the chassis 4.

[0034] The triangular plate 3 includes a lower triangular plate 31, a middle left triangular plate 32, a middle right triangular plate 33 and an upper triangular plate 34 that are connected to each other. The two sides of the upper triangular plate 34 are connected to the finned heat exchanger 1 through the baffles 8.

[0035] The fan mounting structure 5 is installed on the upper triangular plate 34 and the upper end of the finned heat exchanger 1. The fan mounting structure 5 has a grid-shaped structure. A reinforcing plate 9 is provided between the fan mounting structure 5 and the upper end of the finned heat exchanger 1. The fan 6 is installed on the fan mounting structure 5.

[0036] Dividing the triangular plate 3 into multiple areas is beneficial for connecting with the finned heat exchanger 1 and the baffle 8, and also effectively avoids the large noise caused by the overall softness of the plate due to the large overall area of ​​the triangular plate 3.

[0037] The fan mounting structure 5 is a grid-shaped structure, with the fan 6 situated in four square open spaces. The fan 6 is not directly connected to the finned heat exchanger 1. The fan mounting structure 5 is added between the finned heat exchanger 1 and the fan 6, allowing the fan 6 to be mounted on a more stable structure, reducing the noise caused by the vibration of the connection structure due to resonance generated during the operation of the fan 6.

[0038] The angle baffle 8 and the reinforcing plate 9 enhance the aesthetics after connection, and also ensure that the finned heat exchanger 1 is not only stressed on the inner side, but also has an additional stress point on the outer side (e.g. Figure 8 As shown, the finned heat exchanger has three stress points: force F1 applied by the triangular plate 3, force F2 applied by the baffle 8, and force F3 applied by the reinforcing plate 9. The forces are balanced, making the overall structure more stable and thus achieving a noise reduction effect.

[0039] Furthermore, the finned heat exchanger 1 is installed and fixed in a V-shape, and the relative angle between the two finned heat exchangers 1 is 40°.

[0040] Furthermore, a diagonal brace 11 is provided in the upper middle part of the column 2, and the lower end of the diagonal brace 11 is fixed to the chassis 4. The addition of a diagonal brace 11 to each column 2 makes the support of the column 2 more stable.

[0041] Furthermore, the fan mounting structure 5 includes a front upper crossbeam 51, a rear upper crossbeam 52, a left upper crossbeam 53, a right upper crossbeam 54, a middle support beam 55, and a middle upper crossbeam 56. The middle support beam 55 is located between the left upper crossbeam 53 and the right upper crossbeam 54, and the middle upper crossbeam 56 is located between the front upper crossbeam 51 and the rear upper crossbeam 52. The middle support beam 55 is fixed to the finned heat exchanger 1 by a reinforcing plate 9. The front upper crossbeam 51 and the rear upper crossbeam 52 are respectively fixed to the upper triangular plate 34, and the left upper crossbeam 53 and the right upper crossbeam 54 are respectively fixed to the finned heat exchanger 1.

[0042] Furthermore, the reinforcing plate 9 has a U-shaped structure with the outer end bent downwards, and the upper baffle plate 12 is installed on the upper part of the finned heat exchanger 1; the inner end of the reinforcing plate 9 is connected to the intermediate support beam 55, and the outer end of the reinforcing plate 9 is connected to the upper baffle plate 12 of the finned heat exchanger 1.

[0043] Furthermore, the baffle 8 has a trapezoidal structure, with its inner end face connected to the upper triangular plate 34 and its lower end face connected to the upper end of the finned heat exchanger 1.

[0044] Furthermore, the triangular plate 3 and the fan mounting structure 5 are designed with ribs. The ribbed triangular plate 3 and the fan mounting structure 5 are more robust and sturdy, can withstand greater forces, and are more aesthetically pleasing.

[0045] Furthermore, louvers 13 are provided at the upper 1 / 3 of the finned heat exchanger 1.

[0046] Furthermore, the fan 6 is a high-duct, low-noise fan.

[0047] When the noise reduction structure device of the closed heat source tower of this utility model is working, the solution enters from the solution inlet of the finned heat exchanger 1 for circulation (e.g. Figure 7 (As indicated by the red arrow in the image), the wind blows in from between the columns 2 and out from the fan 6 (as shown in the image). Figure 7 (As indicated by the blue arrow in the image). The finned heat exchanger 1 is stably supported by the column 2 and the triangular plate 3, reducing the noise generated by vibration. The vibration generated by the fan 6 during operation is damped by the fan mounting structure 5, reducing the noise generated by the resonance and vibration of the finned heat exchanger 1 and the mounting structure during fan operation. The baffle 8 and the reinforcing plate 9 increase the stress points on the inner and outer sides of the finned heat exchanger 1, making the overall structure of the finned heat exchanger 1 more stable, thereby further reducing noise and ultimately achieving a good noise reduction effect.
