Description

Technical Field

[0001] This application relates to the field of air-cooled units, and more particularly to an air-cooled unit and air conditioning system. Background Technology

[0002] In today's industrial and commercial sectors, air-cooled chiller units are widely used in various scenarios due to their efficient and convenient heat dissipation characteristics. Currently used air-cooled chiller units employ a two-stage radiator design in a V-shape, and this unique structure has demonstrated excellent performance in past heat dissipation practices. This design increases the contact area between the radiator and the air, utilizing airflow to remove heat and achieve highly efficient heat exchange.

[0003] However, with continuous technological innovation, the increasing demand for cooling has brought higher performance indicators and operational requirements to air-cooled units. While meeting cooling needs and improving cooling efficiency, the compressor also generates significantly more heat. The V-shaped radiator suffers from uneven airflow distribution, easily generating eddies or dead zones, leading to low heat exchange efficiency, suboptimal airflow paths, high wind resistance, and increased fan energy consumption. Furthermore, the two-blade radiator structure limits the heat exchange area, affecting the overall performance of the air-cooled unit.

[0004] Therefore, it is necessary to provide an improved air-cooled unit and air conditioning system to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0025] See Figure 1 As shown, this application provides an air-cooled unit 100, including a unit support 10, a fan assembly 20, and a heat exchange assembly 30. The fan assembly 20 and the heat exchange assembly 30 are mounted on the unit support 10. The fan assembly 20 is connected to the heat exchange assembly 30, and the fan assembly 20 is located above the heat exchange assembly 30. In embodiments of this application, there are multiple fan assemblies 20 and heat exchange assemblies 30.

[0026] The unit support frame 10 includes a bottom support 11, a plurality of vertical rods 12, and a plurality of horizontal rods 13. The vertical rods 12 are vertically connected to the bottom support 11. The horizontal rods 13 are connected to the vertical rods 12 and are arranged perpendicular to them. According to an embodiment of this application, some of the horizontal rods 13 are connected to the top of the vertical rods 12, and the remaining horizontal rods 13 are connected to the middle of the vertical rods 12. The heat exchange assembly 30 is connected to the plurality of vertical rods 12 and the horizontal rods 13 located in the middle of the vertical rods 12. The fan assembly 20 is located at the top of the unit support frame 10.

[0027] See Figures 2 to 4 As shown, the fan assembly 20 includes a fan body 21 and a fan cover 22. The fan body 21 is mounted on the fan cover 22, which is mounted on the heat exchange assembly 30. The fan cover 22 and the heat exchange assembly 30 together form a cavity 301 to prevent airflow leakage and ensure concentrated airflow on the inlet side 211 of the fan assembly 20. In the embodiments of this application, two fan bodies 21 are disposed above one heat exchange assembly 30.

[0028] According to other embodiments of this application, the fan cover 22 can be fixed to the heat exchange assembly 30 using mechanical connections such as snap-fit, magnetic attraction, or fixing bolts.

[0029] The side of the fan cover 22 closest to the heat exchange assembly 30 is the air inlet side 211 of the fan body 21, and the opposite side is the air outlet side 212 of the fan body 21. The exterior, cavity 301, air inlet side 211, and air outlet side 212 of the air-cooled unit 100 are sequentially connected to form a high-efficiency air duct. Air flows from the outside through the cavity 301, passes evenly through the heat exchange assembly 30, and then to the air outlet side 212, thereby reducing pressure drop and energy consumption.

[0030] The heat exchange assembly 30 includes four heat exchangers arranged in a W-shape, which, compared to the traditional V-shaped arrangement of two heat exchangers, increases the heat exchange area and improves heat transfer capacity. A fan assembly 20 is mounted on the four heat exchangers, and the fan assembly 20 and the four heat exchangers together form a cavity 301. The cavity 301 is connected to the air inlet side 211 of the fan assembly 20, forming a high-efficiency air duct. This ensures that air passes concentratedly through the four heat exchangers, reducing energy loss and external interference, and improving system reliability.

[0031] The four-stage heat exchanger includes two inner coils 31 and two outer coils 32 connected together. The distinction between the inner and outer coils allows for finer airflow control. The inner coils 31 handle heat exchange located in the middle of the air-cooled unit 100, while the outer coils 32 guide airflow at the edges of the air-cooled unit 100. The height of the outer coils 32 is greater than or equal to the height of the inner coils 31. In embodiments of this application, the inner coils 31 and outer coils 32 can be connected via sheet metal parts at the bottom.

[0032] According to the embodiments of this application, the two inner coil sections 31 are symmetrically arranged with respect to the central axis of the fan assembly 20, and the two outer coil sections 32 are symmetrically arranged with respect to the central axis of the fan assembly 20. The symmetrical arrangement of the heat exchange components 30 ensures airflow balance and system stability, avoids hot spots or vibrations on one side, and improves heat exchange uniformity and the lifespan of the air-cooled unit.

[0033] The two inner coil sections 31 include a first inner coil 311 and a second inner coil 312. The two outer coil sections 32 include a first outer coil 321 and a second outer coil 322. The first outer coil 321, the first inner coil 311, the second inner coil 312 and the second outer coil 322 are connected in sequence and arranged in a W-shape.

[0034] See Figure 2 As shown in the embodiment of this application, the height of the outer coil 32 is equal to the height of the inner coil 31. Specifically, the heights of the first inner coil 311 and the second inner coil 312 are equal to the heights of the first outer coil 321 and the second outer coil 322. The heat exchange assembly 30 also includes a first side baffle 33 and a second side baffle 34 disposed between the fan assembly 20 and the four-stage heat exchanger. The two ends of the first side baffle 33 are respectively connected to the fan cover plate 22 and the first outer coil 321. The two ends of the second side baffle 34 are respectively connected to the fan cover plate 22 and the second outer coil 322.

[0035] According to the embodiments of this application, by increasing the length of the inner coil 31 or the outer coil 32, the heat exchange area of ​​the coil can be increased, thereby increasing the heat exchange area of ​​the entire unit. When the height and length of the four heat exchangers are equal, the W-shaped four-section heat exchanger increases the heat exchange area by about 10% compared to the V-shaped two-section heat exchanger. In the embodiments of this application, when the length of each of the four heat exchangers is 697mm, the height H of the fan assembly 20 and the heat exchange assembly 30 is 1170mm, and its overall height is also less than that of the V-shaped air-cooled unit.

[0036] See Figure 3 As shown, this is another embodiment of the present application. The height of the outer coil 32 is greater than the height of the inner coil 31. Specifically, the heights of the first inner coil 311 and the second inner coil 312 are less than the heights of the first outer coil 321 and the second outer coil 322. The upper ends of the first outer coil 321 and the second outer coil 322 near the fan assembly 20 are both connected to the fan cover plate 22.

[0037] According to another embodiment of this application, the lengths of the first inner coil 311 and the second inner coil 312 are 555.7 mm, and the lengths of the first outer coil 321 and the second outer coil 322 are 832 mm. The height H of the fan assembly 20 and the heat exchange assembly 30 is 1037.6 mm, and its overall height is also less than the height of the V-shaped air-cooled unit.

[0038] The heat exchange assembly 30 also includes side sealing plates 35. The side sealing plates 35 cover the end faces of the four-section heat exchanger to seal the cavity 301, isolating it from the external environment and improving insulation and dustproof capabilities. In the embodiments of this application, the number of side sealing plates 35 is four: two side sealing plates 35 are disposed on the front end face of the four-section heat exchanger, and the other two side sealing plates 35 are disposed on the rear end face of the four-section heat exchanger. The cross-section of the side sealing plates 35 is V-shaped. Alternatively, the number of side sealing plates 35 can also be two: one side sealing plate 35 is disposed on the front end face of the four-section heat exchanger, and the other side sealing plate 35 is disposed on the rear end face of the four-section heat exchanger. In this case, the cross-section of the side sealing plates 35 is W-shaped.

[0039] According to other embodiments of this application, the side sealing plate 35 may be made of thermally insulating composite material or a removable panel, etc.

[0040] This application also provides an air conditioning system, including the air-cooled unit 100 and compressor module 200 as described above. The compressor module 200 is disposed within the unit bracket 10 and located below the heat exchange assembly 30. Specifically, the compressor module 200 is disposed on the bottom bracket 11.

[0041] The heat exchange assembly 30 of this application includes four heat exchangers arranged in a W-shape, resulting in a larger heat exchange area and improved heat transfer capacity, thereby increasing the heat exchange efficiency of the air-cooled unit 100. Simultaneously, the fan assembly 20 and the four heat exchangers together form a cavity 301 communicating with the air inlet side 211 of the fan assembly 20, optimizing the airflow distribution, thereby reducing energy loss and external interference, and improving the reliability of the air-cooled unit 100.

The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
