Description

Technical Field

[0001] This utility model relates to a muffler, specifically an array-type muffler. Background Technology

[0002] A cooling tower is a device used to lower water temperature. It achieves this by exchanging heat through the contact between water and air, using steam evaporation to carry away heat. Cooling towers are primarily used in industrial production and refrigeration / air conditioning systems to cool the water and ensure normal system operation. The working principle of a cooling tower is based on evaporative cooling, convective heat transfer, and radiative heat transfer. It uses water as a circulating coolant, absorbing heat from the system and releasing it into the atmosphere. Cooling towers typically have a packing layer inside, onto which hot water or steam is sprayed. The moisture is then carried away by natural or mechanical airflow, achieving the cooling effect. The design and application of cooling towers involve knowledge from multiple disciplines, including aerodynamics, thermodynamics, fluid mechanics, chemistry, biochemistry, materials science, static structural mechanics, and manufacturing technology. Therefore, a cooling tower is not merely a simple heat dissipation device but a product of the integration of multiple technologies. Silencers are usually installed at the air inlet of a cooling tower to reduce noise during operation.

[0003] Currently, the silencers at the air inlet of cooling towers in existing technologies generally use matrix-type and plate-type silencers, which have excessive flow resistance at the air inlet, thus affecting the air intake efficiency and consequently the cooling efficiency. Therefore, this application proposes an array-type silencer to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an array-type silencer to solve the problem mentioned in the background art that the silencers at the air inlet of the cooling tower generally use matrix-type and plate-type silencers, which have excessive flow resistance at the air inlet, thereby affecting the air intake efficiency and thus the cooling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An array-type silencer includes a wall panel. The wall panel contains several silencer units. The silencer units on the top and bottom sides of the wall panel are semi-hexagonal in design. The silencer units inside the wall panel and located between the semi-hexagonal silencer units are hexagonal in design. Airflow channels are provided between the semi-hexagonal and hexagonal silencer units. A first bracket is fixedly installed on the front sides of the semi-hexagonal and hexagonal silencer units in the same vertical direction. A second bracket is fixedly installed on the rear sides of the semi-hexagonal and hexagonal silencer units in the same vertical direction.

[0007] As a further embodiment of this utility model: the top and bottom of the first bracket and the second bracket are both inserted into the inner wall of the wall panel and slidably connected to the wall panel.

[0008] As a further improvement of this utility model, the inner top and inner bottom sides of the wall panel are provided with sliding grooves for sliding connection with the first bracket and the second bracket.

[0009] As a further improvement of this utility model: the rear side of each of the second brackets abuts against one side of the interior of the two slide grooves.

[0010] As a further embodiment of this utility model: each of the first brackets is symmetrically fixedly installed with a connecting block on its front side, and bolts are provided on the side of the two symmetrical connecting blocks that are close to each other. The bolts pass through the connecting blocks and are threadedly connected to the wall panel. Threaded grooves for threaded connection with the bolts are provided on the wall panel at the position corresponding to each bolt.

[0011] As a further improvement of this utility model, the connecting block is provided with a slot for matching the end of the bolt handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model replaces the traditional matrix and plate silencers with an array-type silencer. The silencer unit adopts a hexagonal structure with a guide fan at its end. The silencer units are connected by a bracket, which reduces the flow resistance during air intake and helps to improve the cooling efficiency of the cooling tower.

[0014] 2. This utility model installs the muffler unit by pushing the first bracket and the second bracket into the interior of the slide groove. When the muffler unit needs to be replaced, the bolts can be removed to pull out the first bracket and the second bracket together with the muffler unit, thus facilitating the replacement of the muffler unit.

[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] Please see Figures 1-3 In this embodiment of the utility model, the array-type silencer includes a wall panel 1. The wall panel 1 has a plurality of silencer units 2 inside. The silencer units 2 on the top and bottom sides of the wall panel 1 are semi-hexagonal in design. The silencer units 2 inside the wall panel 1 and located between the plurality of semi-hexagonal silencer units 2 are hexagonal in design. A guide duct 5 is provided between the semi-hexagonal silencer units 2 and the hexagonal silencer units 2. The front sides of the plurality of semi-hexagonal silencer units 2 and the plurality of hexagonal silencer units 2 in the same vertical direction are fixedly installed with a first bracket 4. The rear sides of the plurality of semi-hexagonal silencer units 2 and the plurality of hexagonal silencer units 2 in the same vertical direction are fixedly installed with a second bracket 6.

[0021] The top and bottom of the first bracket 4 and the second bracket 6 are inserted into the inner wall of the wall panel 1 and are slidably connected to the wall panel 1. The inner top side and inner bottom side of the wall panel 1 are provided with sliding grooves 3 for sliding connection with the first bracket 4 and the second bracket 6. The rear side of each second bracket 6 abuts against the inner side of the two sliding grooves 3, which facilitates the replacement of the silencing unit. The front side of each first bracket 4 is symmetrically fixed with a connecting block 10. The two symmetrical connecting blocks 10 are provided with bolts 9 on the side close to each other. The bolts 9 pass through the connecting block 10 and are threadedly connected to the wall panel 1. The wall panel 1 is provided with a threaded groove 8 for threaded connection with the bolt 9 at the position corresponding to each bolt 9.

[0022] The connecting block 10 has a slot 7 for fitting the rotating end of the bolt 9.

[0023] The working principle of this utility model is as follows:

[0024] In use, the first bracket 4 and the second bracket 6, on which the silencing unit 2 is installed, are pushed into the interior of the wall panel 1 through the upper and lower sliding grooves 3 until the rear side of the second bracket 6 is pressed against one side of the interior of the two sliding grooves 3. At this time, the threaded groove 8 on the wall panel 1 corresponds to the position of the through hole on the connecting block 10. Then, the bolt 9 is passed through the through hole and screwed into the threaded groove 8 on the wall panel 1 until the handle of the bolt 9 is housed in the slot 7. At this time, the silencing unit 2 is installed inside the wall panel 1 by the first bracket 4 and the second bracket 6. When air is intake, the silencing unit 2 is hexagonal, and the air guide duct 5 is located between multiple adjacent silencing units 2. The air enters from the air guide duct 5. Compared with the traditional matrix and plate silencers, the air intake has less flow resistance. When the silencing unit 2 needs to be replaced, the bolt 9 at the corresponding position is unscrewed, so that the first bracket 4 and the second bracket 6 can be pulled out from the interior of the sliding groove 3, thereby pulling out the entire silencing unit 2 together for easy replacement.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
