Description

Technical Field

[0001] This utility model belongs to the field of air conditioning cooling tower technology, specifically relating to a noise reduction cooling tower. Background Technology

[0002] In modern large public buildings, cooling towers are an important component of central air conditioning systems, generating significant noise during operation. Modern building spaces have strict noise environmental assessment requirements, and noise control is equally essential for public areas outside the building. This necessitates sound management measures to address the substantial noise generated by cooling towers. Cooling towers produce mechanical noise during operation, and significant intake noise is also generated at the air inlet of the tower.

[0003] In the noise control of cooling towers, sound barriers are a commonly used noise reduction measure. However, using sound barriers around cooling towers can bring a series of problems. Adding sound barriers will affect the normal air intake of the cooling tower and affect the cooling effect. The height and width of cooling tower sound barriers are generally very large, and they are mostly installed at high places, where they are subjected to high wind pressure. When constructing them, it is necessary to consider whether the original building is solid and whether there is a suitable installation location, which brings great difficulties to the design and construction of cooling towers. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides a noise-reducing cooling tower. By applying noise reduction treatment to the air inlet and the wall of the cooling tower, the noise of the cooling tower is reduced, thus meeting the noise requirements of the existing building environment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a noise-reducing cooling tower, comprising a top cover and a water receiving tray arranged in parallel, wherein the top cover and the water receiving tray are supported by multiple partition baffles, which can play a good supporting role.

[0006] The upper sections of adjacent partition panels are connected by an upper arc-shaped inner wall panel and an upper arc-shaped outer wall panel. An upper cavity is formed between the upper arc-shaped inner wall panel and the upper arc-shaped outer wall panel. The upper cavity is filled with polyurethane foam to form the first sound insulation layer.

[0007] The lower sections of adjacent partition baffles are supported by multiple first chambers. The first chambers are filled with polyurethane foam to form a second sound insulation layer. The adjacent first chambers and the partition baffles on both sides form a lower receiving cavity. A hollow second chamber is arranged in the lower receiving cavity. The lateral width of the second chamber is the same as that of the lower receiving cavity. Multiple ventilation holes are opened on the second chamber, which connect the inner and outer sides of the second chamber. An air intake channel is left between the second chamber and the first chamber placed above to ensure the smooth air intake of the cooling tower.

[0008] The bottom of the water receiving tray is supported by multiple legs, which are arranged at equal angles around the center of the water receiving tray. These legs support the tower body and detach it from the bottom surface, ensuring operational stability.

[0009] Preferably, the number of partition panels is 8, and the 8 partition panels are arranged at equal angles around the center of the top cover.

[0010] An insect-proof net is installed in the middle of the top cover to prevent flying insects from entering the cooling tower.

[0011] A protective net is installed on the outer side of the lower section of the adjacent partition panel. The protective net is a steel wire mesh with large holes. The protective net surrounds the second chamber and plays a protective role.

[0012] As a shape of the noise reduction module, the top of the second chamber is provided with a triangular protrusion, with one side of the triangular protrusion facing outward and the other side of the triangular protrusion facing inward.

[0013] As a shape of the noise reduction module, the top of the second chamber is provided with a hemispherical protrusion, and the arc surface of the hemispherical protrusion is arranged along the air intake direction of the air intake channel.

[0014] Compared with the prior art, the specific beneficial effects of this utility model are as follows: This utility model designs the cooling tower wall as a double-layer wall, and fills the cavity of the cooling tower wall formed by the double-layer wall with polyurethane foam to form a sound insulation layer, which can effectively reduce the large amount of noise generated at the air inlet of the cooling tower. Multiple second chambers are set at the air inlet of the cooling tower, and the multiple second chambers form a structure similar to louvers. When air passes through the second chamber with double-layer holes, the sound reflection effect can reduce the large amount of noise at the air inlet of the cooling tower. The use of second chambers with large holes also effectively reduces the air intake resistance at the air inlet and ensures smooth air intake. Attached Figure Description

Detailed Implementation

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. 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.

[0021] like Figure 1-2 As shown, a noise-reducing cooling tower includes a top cover 1 and a water receiving tray 2 arranged in parallel. The top cover 1 and the water receiving tray 2 are supported by multiple partition baffles 3, which can play a good supporting role. An insect-proof net 12 is installed in the middle of the top cover 1 to prevent flying insects from entering the cooling tower. The water receiving tray 2 is used to collect water.

[0022] The upper inner side of the adjacent partition baffle 3 is seamlessly welded with an upper arc-shaped inner wall panel 4, and the upper outer side of the adjacent partition baffle 3 is seamlessly welded with an upper arc-shaped outer wall panel 5. A hollow double-layer upper cavity is formed between the upper arc-shaped inner wall panel 4 and the upper arc-shaped outer wall panel 5. The upper arc-shaped inner wall panel 4, the upper arc-shaped outer wall panel 5 and the partition baffle 3 are all made of stainless steel. Polyurethane foam is filled in the upper cavity to form the first sound insulation layer 6.

[0023] The lower sections of adjacent partition panels 3 are supported by multiple first chambers 7. The first chambers 7 are filled with polyurethane foam to form a second sound insulation layer 8, which further improves the sound insulation effect.

[0024] The adjacent first chamber 7 and the partition baffles 3 on both sides form a lower receiving cavity. A hollow second chamber 9 is arranged in the lower receiving cavity. The lateral width of the second chamber 9 is the same as the lateral width of the lower receiving cavity. The interior of the second chamber 9 is hollow. Multiple ventilation holes 10 are opened on the outer wall of the second chamber 9. The ventilation holes 10 connect the inner and outer sides of the second chamber 9. An air intake channel is left between the second chamber 9 and the first chamber 7 placed above to ensure the smooth air intake of the cooling tower.

[0025] The bottom of the water receiving tray 2 is supported by multiple legs 11. The multiple legs 11 are arranged at equal angles around the center of the water receiving tray 2. The multiple legs 11 support the tower body and detach it from the bottom surface to ensure the stability of operation.

[0026] Preferably, the number of partition baffles 3 is 8, and the 8 partition baffles 3 are arranged at equal angles around the center of the top cover 1.

[0027] A protective net is arranged on the outer side of the lower section of the adjacent partition baffle 3. The protective net is a steel wire mesh with large holes. The protective net surrounds the second chamber 9 and plays a protective role.

[0028] like Figure 3 As shown, as a shape of the noise reduction module, the top of the second chamber 9 is provided with a triangular protrusion 13, one side of the triangular protrusion 13 is placed on the outside, and the other side of the triangular protrusion 13 is placed on the inside. Multiple second chambers 9 are arranged to form a shape similar to venetian blinds.

[0029] like Figure 4 As shown, as a shape of the noise reduction module, the top of the second chamber 9 is provided with a hemispherical protrusion 14. The arc-shaped surface of the hemispherical protrusion 14 is arranged along the air intake direction of the air intake channel. The arc-shaped air intake channel can ensure smooth airflow and avoid howling and unnecessary noise.

[0030] This invention designs the cooling tower wall as a double-layer wall, and fills the cavity of the cooling tower wall formed by the double-layer wall with polyurethane foam to form a sound insulation layer, which can effectively reduce the large amount of noise generated at the air inlet of the cooling tower.

[0031] Multiple second chambers 9 are installed at the air inlet of the cooling tower, forming a structure similar to louvers. When air passes through the second chambers 9 with double-layered perforations, sound waves are scattered and absorbed upon encountering them. Upon encountering the inner side of the second chambers 9, the sound waves are reflected and diffracted. Some of the reflected sound waves reduce noise, while some diffracted sound waves form a sound shadow zone behind them, where sound wave interference occurs, thus significantly reducing sound noise. Furthermore, an air intake channel is provided between the second chambers 9 and the first chamber 7 located at the top, ensuring unobstructed airflow into the cooling tower.

[0032] Due to the effect of sound reflection, a large amount of noise at the air inlet of the cooling tower can be reduced. The use of a second chamber 9 with large holes also effectively reduces the air intake resistance at the air inlet, ensuring smooth air intake.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall be included within the scope of the present utility model.
