[0002] In integrated chillers, the condensing unit typically uses air or water cooling for heat dissipation. However, when using air cooling alone, the heat dissipation efficiency is limited by the heat transfer capacity of the air. As the surrounding air temperature rises, the air's heat dissipation efficiency decreases, and its ability to continue absorbing heat weakens, resulting in reduced heat dissipation efficiency and poor cooling. When using water cooling alone, the water spray may not evenly cover the entire surface of the condensing unit to be cooled, resulting in poor heat dissipation in certain areas.

[0029] Please refer to Figures 1 to 6 The present invention proposes an integrated chiller 100, which includes: a shell 10, the shell 10 is provided with a accommodating chamber 11, the shell 10 is provided with an air inlet 12 and an air outlet 13 connected to the accommodating chamber 11, and the air inlet 12 is opened on opposite sides of the shell 10; a condenser assembly 20, the condenser assembly 20 is arranged in the accommodating chamber 11, and the condenser assembly 20 is arranged close to the air inlet 12; a wet film 30, the wet film 30 is arranged in the accommodating chamber 11 and is located on the side of the condenser assembly 20 facing the air inlet 12; and a water distributor (not shown in the figure), the water distributor is installed in the accommodating chamber 11, and the water outlet of the water distributor is located above the wet film 30.

[0030] Specifically, the integrated chiller 100 includes a shell 10, a condenser assembly 20, a wet film 30 and a water distributor. The shell 10 is used to install and protect internal components. The condenser assembly 20 is used to cool gas or steam and convert it into liquid. The water distributor is used to spray water and spray the water onto the wet film 30. The wet film 30 is arranged close to the condenser assembly 20. The wet film 30 is used to receive and guide water, which increases the actual contact area between water and air, is beneficial to the evaporation of water, and improves the heat dissipation effect of the condenser assembly 20.

[0031] The air inlet 12 and the air outlet 13 are connected to form an air duct, and the condenser assembly 20 and the wet film 30 are both arranged close to the air inlet 12. Therefore, when the water distributor sprays water to the wet film 30, the water flows through various parts of the wet film 30 by gravity, thereby increasing the contact area between water and air. When in use, the air passes through the wet film 30 and the temperature drops, so it can better take away more heat in the condenser assembly 20, forming a combined heat dissipation structure of air cooling and water cooling.

[0032] At the same time, air inlets 12 are provided on opposite sides of the housing 10. Air inlet from both sides ensures that air flows evenly into the housing 10, avoiding airflow deviation caused by unilateral air inlet. By allowing air to enter from both sides simultaneously, hot spots caused by uneven airflow can be reduced, helping to maintain overall temperature consistency. The opposite sides of the housing 10 can be the front and back, or the two side surfaces.

[0033] The wet film 30 can be placed around the condenser assembly 20 or attached to one side of the condenser assembly 20. As air passes through the wet film 30, water evaporates from the film 30 into the air. This evaporation of water from the wet film 30 absorbs heat, improving the condensation efficiency of the condenser assembly 20. Water is released to the wet film 30 through a water distributor. The wet film 30 is positioned close to the condenser, and an air duct is provided to dissipate heat from the condenser assembly 20 and evaporate the water on the wet film 30, resulting in an overall better cooling effect.

[0034] The evaporative condensing unit can be used in air-conditioning systems. The condenser cools the high-temperature and high-pressure refrigerant vapor discharged from the compressor 101, liquefies it, and removes the released heat through the cooling medium. It can also be used in chiller systems, industrial production, power plants and other fields.

[0035] The technical solution of the present invention is to set a wet film 30 on the side of the condenser assembly 20 facing the air inlet 12. The wet film 30 is set close to the water distributor. The water distributor ensures that water is evenly distributed on the wet film 30. Under the action of gravity, water penetrates downward along the wet film 30, and the contact area between air and water is increased through the wet film 30. Air inlets 12 are provided on the opposite sides of the shell 10. The air inlets on both sides can ensure that the air flows into the interior of the shell 10 evenly. After the wind passes through the wet film 30, the temperature drops significantly, so that the evaporation of water in the wet film 30 is used to absorb heat. When the cooled air passes through the condenser again, it can take away more heat in the condenser. The heat is dissipated by the combination of water cooling and air cooling, which improves the condensation efficiency of the condenser assembly 20 and achieves a good and uniform cooling effect.

[0036] In an embodiment of the present invention, two air outlets 13 are provided. The two air outlets 13 are provided at the top of the housing 10 , and each air outlet 13 is provided correspondingly to one air inlet 12 .

[0037] In detail, two air outlets 13 are set corresponding to the air inlet 12, which can achieve more effective airflow guidance. After the air enters from both sides of the shell 10, it flows directly through the condenser assembly 20 and is then discharged from the corresponding top air outlet 13. The condenser assembly 20 and the wet film 30 are set close to the air inlet 12, which can ensure that the air quickly reaches the condenser assembly 20 and the wet film 30 and quickly takes away the heat.

[0038] This design allows heat to be discharged from the corresponding air outlet 13 on the top through the shortest path, reducing the residence time of heat in the shell 10. The design of air inlet on both sides and air outlet on the top can ensure that the airflow is evenly distributed throughout the shell 10, avoiding local overheating and making the temperature inside the entire shell 10 more uniform.

[0039] In an embodiment of the present invention, the integrated chiller 100 further includes a circulation fan 50 , and each of the air outlets 13 is provided with a circulation fan 50 .

[0040] It is noteworthy that a circulation fan 50 is provided at each air outlet 13. The provision of the circulation fan 50 can enhance the air flow velocity at the air outlet 13, ensure sufficient air flow around the condenser assembly 20, speed up the exhaust speed of hot air, and thus improve the cooling efficiency.

[0041] In an embodiment of the present invention, two groups of the condenser components 20 and the wet films 30 are provided, and the two groups of the condenser components 20 are respectively arranged close to the two air inlets 12, and the two groups of the wet films 30 are respectively arranged on the side of the two groups of the condenser components 20 facing the air inlets 12.

[0042] In detail, the condenser assembly 20 and the wet film 30 are each provided in two groups and are separately arranged at two air inlets 12. Under high load conditions, the total heat exchange area can be increased, the heat exchange efficiency can be improved, and the heat exchange process can be accelerated, thereby enhancing the cooling capacity of the entire equipment. For large systems or applications requiring higher cooling capacity, higher cooling requirements can be met. The reasonable layout of the condenser assembly 20 and the wet film 30 optimizes the thermal management of the entire equipment.

[0043] In an embodiment of the present invention, the condenser assembly 20 includes a condenser body 21 and a support frame 22 . The support frame 22 is fixedly connected to the shell 10 . The condenser body 21 is mounted on the support frame 22 . The wet film 30 is mounted on the support frame 22 .

[0044] Specifically, the condenser body 21 is installed using a support frame 22, such as Figure 3 and Figure 4The condenser body 21 is fixed on the support frame 22, and the wet film 30 is also fixed on the support frame 22. The support frame 22 is fixedly connected to the shell 10, which can provide stable support to ensure that the condenser body 21 and the wet film 30 will not be displaced or damaged due to vibration or external force, and are easy to disassemble and install; the support frame 22 is hollowed out, and the remaining water can flow to the bottom of the shell 10 for collection and reuse; integrating the condenser body 21 and the wet film 30 on the same support frame 22 can save space and improve the space utilization inside the shell 10.

[0045] In an embodiment of the present invention, the wet film 30 includes multiple pieces, the condenser body 21 includes multiple condensation layers (not shown in the figure), the multiple condensation layers are arranged at intervals along the height direction, and the wet film 30 is arranged in two adjacent condensation layers.

[0046] In detail, the condensation layer refers to the pipe layer formed by the condensation tube extending along the height direction. There is a gap between adjacent condensation layers. Multiple wet films 30 are arranged. By placing the wet film 30 between two adjacent condensation layers, it can be ensured that the air can contact the condensation layer multiple times when passing through the wet film 30, thereby increasing the number of heat exchanges between the air and the condenser, and can make fuller use of the cooling effect of the wet film 30 to improve the overall cooling efficiency. At the same time, the multiple interactions between the wet film 30 and the condensation layer can increase the contact area and time between the air and the condenser, thereby improving the heat exchange efficiency.

[0047] In an embodiment of the present utility model, a partition 60 is also provided in the shell 10, and the partition 60 divides the accommodating cavity 11 into a first cavity 14 and a second cavity 15. The air inlet 12 and the air outlet 13 are both connected to the first cavity 14, and the condenser assembly 20, the wet film 30 and the water distributor are all arranged in the first cavity 14; the integrated chiller 100 also includes a circulating water pump 70, which is arranged in the second cavity 15, and the circulating water pump 70 is connected to the first cavity 14 and the water distributor.

[0048] Specifically, the shell 10 is divided into a first cavity 14 and a second cavity 15 by setting a partition 60. The first cavity 14 is used to install a water distributor, a condenser assembly 20 and a wet film 30, so that a circulating water tank 61 is formed in the first cavity 14. The remaining water will flow into the first cavity 14. By setting a circulating water pump 70 to connect the first cavity 14 and the water distributor, water can continue to flow between the first cavity 14 and the water distributor, which can maintain the normal operation of the system. The circulating water pump 70 can provide the necessary pressure to ensure that water flows along a predetermined path in the system.

[0049] At the same time, since the air inlet 12 and the air outlet 13 are both arranged in the first cavity 14, the air flow path is clear, which can ensure that the air directly contacts the condenser assembly 20 and the wet film 30 after the air duct, thereby more effectively performing heat exchange and helping to improve cooling efficiency.

[0050] The separate design helps avoid direct contact between water and electrical components, reducing potential safety hazards, such as preventing condensate from damaging the water pump, and helping to extend the overall service life of the equipment. It also facilitates subsequent maintenance and inspection. For example, if cleaning the condenser or inspecting the circulating water pump 70 is required, these operations can be performed in separate chambers without interfering with each other.

[0051] The specific structure of the separator 60 can be set according to the actual required cavity shape, and can be set as a single plate or as multiple plates connected by bending.

[0052] In an embodiment of the present utility model, a partition 16 is further provided in the second cavity 15, and the partition 16 divides the second cavity 15 into a first installation space 151 and a second installation space 152, and the circulating water pump 70 is installed in the second installation space 152; the integrated chiller 100 also includes a distribution box 80 or a chilled water tank, and the distribution box 80 or the chilled water tank is installed in the first installation space 151 and placed on the partition 16.

[0053] It is worth noting that Figure 4 A partition 16 is also provided in the second cavity 15, which divides the second cavity 15 into a first installation space 151 above and a second installation space 152 below. The first installation space 151 is used to install the distribution box 80 or the chilled water tank, and the second installation space 152 is used to install other equipment such as the compressor 101 and the liquid storage tank 102.

[0054] The second cavity 15 is further divided by the partition 16, so that equipment with different functions can be separated. Different equipment is located in different spaces and can be maintained and repaired independently. The mutual influence between electrical equipment and water-related equipment can be reduced, the safety can be improved, the space can be fully utilized, the waste of space can be avoided, and centralized management is facilitated.

[0055] In an embodiment of the present invention, the distribution box 80 is installed in the first installation space 151 , and the housing 10 is provided with an opening 17 at the position of the distribution box 80 . A detachable cover 18 is provided at the opening 17 .

[0056] Detailed, such as Figure 2The design of the opening 17 and the detachable cover 18 allows for quick access to the distribution box 80, facilitating maintenance, inspection or emergency processing. There is no need to dismantle the entire housing 10. Necessary operations can be performed by simply opening the cover 18, which improves work efficiency, facilitates daily management and inspection, ensures that the distribution box 80 is in good working condition, and improves safety. Normally, the cover 18 is closed to protect the distribution box 80 from the influence of the external environment and reduce the risk of entry of pollutants such as dust and moisture.

[0057] In an embodiment of the present utility model, the partition 60 includes a circulating water tank 61 and a baffle 62. The circulating water tank 61 is arranged in the shell 10. The baffle 62 is connected to the circulating water tank 61 and is used to cooperate with the side wall of the circulating water tank 61 to separate the accommodating cavity 11 into a first cavity 14 and a second cavity 15.

[0058] It is worth noting that the circulating water tank 61 and the baffle 62 cooperate to separate the accommodating chamber 11 into a first cavity 14 and a second cavity 15. The circulating water tank 61 is located in the first cavity 14, and the remaining water on the water distributor, condenser assembly 20 and wet film 30 will flow into the circulating water tank 61.

[0059] The circulating water tank 61, as one of the partitions 60, serves both as a water storage device and as a space divider. This eliminates the need for additional partitioning structures, simplifies the internal layout, and fully utilizes the internal space of the housing 10. This integrated water storage and partitioning function simplifies system design. Furthermore, the circulating water tank 61, acting as a partition 60, reduces the risk of water leakage and improves safety. Adjusting the position of the circulating water tank 61 allows for flexible adjustment of the spatial distribution between the first cavity 14 and the second cavity 15.

[0060] In addition, the evaporative cooling integrated chiller 100 further includes a compressor 101 and a liquid storage tank 102 . The compressor 101 and the liquid storage tank 102 are both arranged in the second cavity 15 . The compressor 101 is connected to the condenser assembly 20 , and the liquid storage tank 102 is communicated with the condenser assembly 20 .

[0061] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
