Description

Technical Field

[0001] This utility model relates to the field of cooling technology, specifically to a dry cooler. Background Technology

[0002] Ultra-large dry coolers are mainly used in cooling systems for large industrial facilities, data centers, etc. Their function is to dissipate the heat of high-temperature fluids into the atmosphere through air cooling, thereby achieving the cooling and temperature reduction of the fluids.

[0003] Large-scale dry-cooled chillers have a large cooling capacity. When the actual demand is low, these chillers still consume a significant amount of electricity to operate, but the cooling output far exceeds the actual requirement, leading to energy waste. Even under low-power demand, the compressors, fans, and other components of large-scale dry-cooled chillers still need to operate according to their own operating parameters. Prolonged operation under this low-load condition may increase equipment wear and tear and shorten its lifespan, which, in the long run, also represents a waste of resources. Utility Model Content

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0025] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this patent. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0026] In related technologies, ultra-large dry coolers have a large cooling capacity. When the actual demand is low, the dry cooler still consumes a large amount of electrical energy to operate, but its cooling output far exceeds the actual need, leading to energy waste. Even under low-power demand, the compressor, fan, and other components of the ultra-large dry cooler still need to operate according to their own operating parameters. Long-term operation under this low-load state may increase equipment wear and shorten its service life, which is also a waste of resources in the long run. There are also problems such as excessive noise during operation and low utilization of the internal flow field of the dry cooler.

[0027] In view of this, the present invention provides a dry cooler, such as... Figure 1-4 As shown, a dry cooler includes a frame 10 and two end plates 50, which are respectively disposed at both ends of the frame 10 in its length direction, and the two end plates 50 and the frame 10 form a cavity; characterized in that it further includes a plurality of first partitions 20 and a plurality of second partitions 30, the first partitions 20 extending along the width direction of the frame 10, and the plurality of first partitions 20 being spaced apart in the cavity along the length direction of the frame 10, thereby dividing the cavity into a plurality of sub-cavities;

[0028] The second partition 30 extends along the length of the frame 10. The multiple second partitions 30 correspond one-to-one with the multiple sub-cavities. The second partition 30 is disposed in the sub-cavities and divides the sub-cavities into two air ducts. The two air ducts are respectively provided with an air inlet area 12 communicating with the corresponding air duct on their opposite sides. The top of the two air ducts is respectively provided with an air outlet area 11 communicating with the corresponding air duct.

[0029] Specifically, it also includes multiple fans 110, multiple heat exchange components 120, multiple sub-inlet pipes 122, and multiple sub-outlet pipes 121. Each air outlet zone 11 is provided with at least two fans 110, and the at least two fans 110 are arranged at intervals along the length direction of the frame 10. Each air inlet zone 12 is provided with at least two heat exchange components 120, and the at least two heat exchange components 120 are arranged sequentially along the height direction of the frame 10. Each air inlet zone 12 is provided with one sub-inlet pipe 122 and one sub-outlet pipe 121. The inlets and outlets of all the heat exchange components 120 in each air inlet zone are respectively connected to the corresponding sub-inlet pipe 122 and the corresponding sub-outlet pipe 121 through pipelines.

[0030] By setting a first and second partition, the interior of the dry cooler is divided into multiple air ducts. When the cooling demand is low, the fans and heat exchange components of some air ducts can be operated, which can reduce energy consumption. The number of fans operating in the ultra-large dry cooler can be flexibly adjusted according to the cooling demand, which helps to achieve energy-saving goals and reduce operating costs. Specifically, each sub-cavity has two air ducts, and each air duct is equipped with four fans and four heat exchange components. Each air duct can operate independently, and the working time and load are relatively reduced. This helps to reduce fan wear, extend the service life of fans and related equipment, and reduce equipment maintenance costs and replacement frequency.

[0031] In some embodiments, all heat exchange components 120 of each air inlet zone 12 have the same angle relative to the height direction of the frame 10. The heat exchange components 120 located on both sides of the same sub-cavity have a gradually increasing distance between corresponding heat exchange components 120 in the height direction of the frame 10 and from the bottom to the top of the frame 10.

[0032] In some embodiments, a plurality of spray pipes 40 are also included, each of which corresponds to one of the heat exchange components 120; the spray pipes 40 are disposed on the side of the heat exchange component 120 away from the second partition 30, and the spray pipes 40 are used to cool the airflow flowing toward the heat exchange component 120.

[0033] In some embodiments, the spray pipe 40 is arranged along the length direction of the frame 10, and a plurality of spray heads 41 are provided on the spray pipe 40, with the plurality of spray heads 41 spaced apart along the length direction of the spray pipe 40. The liquid inlet end of the spray pipe 40 is used to connect to an external cooling water source, and the spray pipe 40 is used to provide cooling water to the spray heads 41, which are used to spray cooling water onto the corresponding heat exchange components 120. The spray heads 41 can form uniform atomized droplets, further cooling the gas flowing towards the heat exchange components 122, significantly improving the heat exchange efficiency of the dry cooler, and is suitable for cooling requirements in high heat flux density scenarios.

[0034] In some embodiments, a spray pipe support is also included, which is disposed on the frame 10. The spray pipe support is provided with a plug portion 42 for mounting the spray pipe 40. The plug portion 42 is provided with a through hole for the spray pipe 40 to pass through, and the spray pipe 40 passes through the through hole.

[0035] Specifically, the insertion part 42 can be a clamp set on the bracket or a through hole directly opened on the bracket; the clamp consists of two metal ears and a fastening bolt, the two metal ears are joined together to form the through hole, and the clamp fastens the spray pipe to the frame 10 by tightening the bolt; or the through hole is directly opened on the bracket. The spray pipe 40 is directly installed with the frame 10 through insertion.

[0036] To further optimize the airflow field within the duct, in some embodiments, such as Figure 3 As shown, it also includes multiple guide plates 31, which are inclinedly arranged on the two side walls of the second partition 30, and the multiple guide plates 31 are arranged at intervals along the height direction of the frame 10. The guide plates 31 are used to turn the airflow flowing to the second partition 30 toward the direction of the air outlet 11, and the guide plates 31 can make the airflow smoother in the process of flowing toward the fan.

[0037] In some embodiments, in the height direction of the frame 10 and in the direction from the bottom of the frame 10 to the top of the frame 10, the included angle between the plurality of guide plates 31 and the second partition plate 30 increases sequentially.

[0038] In some embodiments, the guide plate 31 includes a connecting area 311 and a bending area 312 bent and connected to the top of the connecting area. The connecting area 311 is attached to the side wall of the second partition 30, and the included angle between the bending area 312 and the second partition 30 is formed as the included angle α between the guide plate 31 and the second partition 30.

[0039] In some embodiments, the included angle α ranges from 10 degrees to 40 degrees. Specifically, refer to... Figure 3 In this embodiment, three guide plates 31 are provided. Along the height of the frame 10 and from the bottom to the top of the frame 10, the angles between the three guide plates 31 and the second partition 30 are 15 degrees, 25 degrees, and 35 degrees, respectively. This invention does not impose special limitations on the angles between the guide plates 31 and the second partition 30; these angles can be adjusted according to actual needs. This invention changes the flow direction of the airflow entering the duct at the bottom of the dryer / cooler by using the guide plates 31, guiding the airflow towards the direction of the fan, reducing the direct impact of the airflow on the second partition 30, improving the airflow effect within the dryer / cooler duct, and also reducing the noise during dryer / cooler operation to some extent.

[0040] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
