Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] Please refer to Figures 1 to 4The present invention proposes an evaporative cooling integrated chiller 100, which includes: a shell 10, the shell 10 has an upper cavity 11 and a lower cavity 12, the shell 10 is provided with an air inlet 13 and an air outlet 14, the air inlet 13 is arranged between the upper cavity 11 and the lower cavity 12, and is communicated with the upper cavity 11, and the air outlet 14 is arranged on the top wall of the upper cavity 11; a condenser assembly 20, the condenser assembly 20 is arranged in the upper cavity 11; and a water separator (not shown in the figure), the water separator is arranged at the top of the shell 10, and the water separator port of the water separator is arranged toward the condenser assembly 20.

[0028] Specifically, the evaporative cooling integrated chiller 100 includes a shell 10, a condenser assembly 20 and a water separator. The shell 10 is provided with an upper cavity 11 and a lower cavity 12. The upper cavity 11 is used to install and fix the condenser assembly 20 and the water separator, and the lower cavity 12 is used to collect remaining water and install other components; the condenser assembly 20 is used to cool gas or steam and convert it into liquid; the water separator is used to spray water, and the water is sprayed into the condenser assembly 20 and the upper cavity 11.

[0029] The air inlet 13 of the shell 10 is arranged between the upper cavity 11 and the lower cavity 12, and the air outlet 14 is arranged on the top wall of the upper cavity 11, so as to form an air duct with air entering from below and air exiting from above; at the same time, the water divider sprays water downward from the top of the shell 10, so that the falling direction of water is opposite to the air flow direction.

[0030] When the direction of water flow is opposite to the direction of air flow, the contact time and contact area between water and air will increase, and more heat can be transferred from the air to the water, thereby improving the cooling efficiency of the condenser assembly 20 and improving the overall cooling effect.

[0031] Specifically, water flows from top to bottom, and air flows from bottom to top, so that hot air contacts the coldest water, and hot water contacts the cold air. Since heat is always transferred from a high temperature to a low temperature, heat exchange is most effective under this reverse flow condition, which can improve the heat exchange efficiency. At the same time, the water gradually heats up during the entire cooling process, while the air gradually cools down, which ensures that the temperature changes more evenly throughout the process, avoiding local overheating or overcooling, thereby improving the overall cooling performance.

[0032] In addition, since the air at the bottom of the lower cavity 12 is relatively cool, the evaporation rate of water can be reduced, thereby saving water resources for secondary utilization.

[0033] The size of the air inlet 13 and the size of the air outlet 14 can be set according to actual needs, as long as the air flows from bottom to top. The number of the air inlet 13 and the number of the air outlet 14 can also be set according to actual needs to adapt to different cooling requirements and environmental conditions.

[0034] The evaporative cooling integrated chiller 100 can be applied to air conditioning systems. The condenser assembly 20 cools the high-temperature and high-pressure refrigerant vapor discharged from the compressor 60 to liquefy it, and the released heat is taken away by the cooling medium. It can also be applied to industrial production or power plants.

[0035] The technical solution of the present invention is to arrange the air inlet 13 between the upper cavity 11 and the lower cavity 12, the air outlet 14 on the top wall of the upper cavity 11, and the water divider on the top of the shell 10, so that the air inlet direction is opposite to the water falling direction, the water flows from top to bottom, and the air flows from bottom to top, so that the contact time and contact area between water and air are increased. In the case of countercurrent, heat can be transferred from the air to the water, thereby improving the cooling efficiency and achieving a better cooling effect.

[0036] In an embodiment of the present invention, the air inlet 13 is opened along the circumference of the housing 10 .

[0037] In detail, the air inlet 13 opened along the circumference can allow air to enter the upper cavity 11 more evenly, thereby ensuring a more uniform airflow distribution in the entire cooling area where the condenser assembly 20 is located, and can reduce dead corners in the upper cavity 11 that are not easily covered by the airflow, so that the air can contact the condenser assembly 20 more comprehensively, and through heat exchange with water, it helps to improve the cooling efficiency and avoid the problem of local overheating.

[0038] At the same time, the circumferentially opened air inlet 13 can provide a larger total opening area, allowing more space for air to enter the system, thereby increasing the air intake volume. Due to the increase in the air intake area, the efficiency of the entire cooling system can be improved.

[0039] In one embodiment, if Figure 1 The shell 10 is configured to be in a rectangular parallelepiped shape, and the air outlets 14 are opened along the four sides of the shell 10 .

[0040] In the embodiment of the present invention, a grille 16 is provided at the air inlet 13 .

[0041] It is worth noting that Figure 1 A grille 16 is provided at each air inlet 13. Providing a grille 16 at the air inlet 13 can prevent larger foreign objects from entering the interior of the device, protect the internal components from damage, and guide the airflow to be more evenly distributed in the condenser assembly 20 and the upper cavity 11, thereby improving the heat exchange efficiency.

[0042] In an embodiment of the present invention, a plurality of air outlets 14 are provided, and the plurality of air outlets 14 are evenly spaced apart on the top wall of the upper cavity 11 .

[0043] In detail, there are multiple air outlets 14, and multiple air outlets 14 can be matched with multiple air inlets 13. A larger air outlet area allows more air to be discharged from the upper cavity 11 at the same time, which can quickly discharge a large amount of heat and ensure that the airflow is evenly distributed in the upper cavity 11, avoiding local airflow that is too fast or too slow, which helps to maintain the airflow balance inside the system and improve the cooling efficiency. Increasing the air outlet area allows more air to contact water, thereby enhancing the heat exchange effect.

[0044] By making full use of the space and rationally arranging multiple air inlets 13 and multiple air outlets 14, the space inside the shell 10 can be better utilized, so that the air can more fully cover the area that needs to be cooled and exchange heat with water, further improving the cooling capacity of the condenser assembly 20.

[0045] In the embodiment of the present invention, a circulation fan 30 is provided at the air outlet 14 .

[0046] It is worth noting that Figure 1 A circulation fan 30 is provided at each air outlet 14. The circulation fan 30 can enhance the air flow velocity at the air outlet 14, ensure sufficient air flow around the condenser assembly 20, speed up the exhaust speed of hot air, and thus improve the cooling efficiency.

[0047] In an embodiment of the present invention, the evaporative cooling integrated chiller 100 further includes a wet film 40 , which is disposed between the condenser assembly 20 and the air inlet 13 and extends along the direction of the condenser assembly 20 .

[0048] Specifically, Figure 2 A wet film 40 is provided between the condenser assembly 20 and the air inlet 13. When the air passes through the wet film 40, water evaporates from the wet film 40 into the air. The evaporation of water in the wet film 40 can be used to absorb heat and perform cooling.

[0049] The wet film 40 cooperates with the air duct on the shell 10. The wet film 40 is arranged close to the air inlet 13 and also close to the condenser assembly 20, and is extended along the direction of the condenser assembly 20 to obtain a larger contact area with the condenser assembly 20. By setting the wet film 40, the actual contact area between water and air can be increased, which is beneficial to the evaporation of water, and can improve the heat dissipation effect of the condenser assembly 20, thereby achieving a good cooling effect.

[0050] In an embodiment of the present invention, a partition 15 is provided in the lower cavity 12, and the partition 15 divides the lower cavity 12 into a first chamber 121 and a second chamber 122, and the first chamber 121 is connected to the upper cavity 11; the evaporative cooling integrated chiller 100 also includes a circulating water pump 50, and the circulating water pump 50 is provided in the second chamber 122, and the circulating water pump 50 is connected to the first chamber 121 and the water distributor.

[0051] In detail, the lower cavity 12 is divided into a first chamber 121 and a second chamber 122 by setting a partition 15. The first chamber 121 is connected to the upper cavity 11 to receive the remaining water for secondary use, and the second chamber 122 is used to install the circulating water pump 50.

[0052] A circulating water tank 17 is formed in the first chamber 121, and the remaining water flows into the first chamber 121. The first chamber 121 and the water distributor are connected by arranging a circulating water pump 50, so that water can continuously flow between the upper chamber 11, the water distributor and the first chamber 121, thereby maintaining the normal operation of the system. The circulating water pump 50 can provide the necessary pressure to ensure that water flows along a predetermined path in the system.

[0053] The separation design helps to avoid direct contact between water and electrical components, reduces potential safety hazards, such as preventing condensed water from damaging the circulating water pump 50, helps to extend the overall service life of the equipment, and also facilitates subsequent maintenance and repair work. For example, if it is necessary to clean the condenser assembly 20 or check the circulating water pump 50, they can be done in different cavities respectively without interfering with each other.

[0054] At the same time, the air inlet 13 and the air outlet 14 are both connected to the upper cavity 11, and the air flow path is clear, which can ensure that the air directly contacts the condenser assembly 20 after entering from the air inlet 13, thereby more effectively performing heat exchange and helping to improve cooling efficiency.

[0055] like Figure 3 A water tank 17 is formed in the first chamber 121. The first filter membrane and the second filter membrane are fixedly installed at a position between the water tank 17 and the wet membrane 40 inside the first chamber 121. The first filter membrane and the second filter membrane are distributed in parallel inside the first chamber 121. The circulating water pump 50 is connected to the water tank 17 for secondary use.

[0056] In an embodiment of the present invention, the partition 15 includes a first section 151 and a second section 152, the first section 151 is vertically arranged in the lower cavity 12, one side of the second section 152 is connected to the free end of the second section 152, and the other side of the second section 152 extends and is connected to the inner wall of the shell 10 near the bottom of the air inlet 13, and the second section 152 is inclined.

[0057] It is worth noting that Figure 4 The first section 151 of the partition 15 is arranged vertically so that the first chamber 121 and the second chamber 122 are separated vertically. The second section 152 of the partition 15 is connected to the shell 10 and is arranged at an angle so that the first chamber 121 and the second chamber 122 are completely separated and help guide the water flow to the bottom of the first chamber 121 so that the water can flow more smoothly to the circulating water pump 50. This design reduces the dead corners of the water flow and avoids the formation of water accumulation and sediment.

[0058] The design of the partition 15 can effectively control the water flow, prevent water from overflowing or flowing into areas that should not be entered, thereby improving the safety of the equipment.

[0059] In an embodiment of the present invention, the evaporative cooling integrated chiller 100 also includes a compressor 60 and a liquid storage tank 70, both of which are arranged in the second chamber 122, the compressor 60 is connected to the condenser assembly 20, and the liquid storage tank 70 is connected to the condenser assembly 20.

[0060] Specifically, by connecting the compressor 60 to the condenser assembly 20, it is possible to ensure that the refrigerant can circulate through the system quickly and effectively, thereby improving the refrigeration efficiency. The liquid storage tank 70 is connected to the condenser assembly 20, which ensures that there is sufficient refrigerant reserve in the system and also helps to stabilize the operation of the system.

[0061] Placing the compressor 60, the liquid storage tank 70 and other major components together in the second chamber 122 can make better use of the space, make the overall structure more compact, facilitate maintenance and repair, and improve safety.

[0062] Furthermore, in one embodiment, if Figure 2 , two compressors 60 and two liquid storage tanks 70 are provided, and two groups of condenser assemblies 20 are provided, and each group of condenser assemblies 20 is equipped with a group of compressors 60 and liquid storage tanks 70. Under high load conditions, the total heat exchange area can be increased, and the heat exchange efficiency can be improved, thereby improving the cooling capacity of the entire evaporative cooling integrated chiller 100. For large systems or applications requiring higher refrigeration capacity, higher refrigeration requirements can be met.

[0063] In an embodiment of the present invention, the evaporative cooling integrated chiller 100 further includes an evaporator 80 , which is disposed in the second chamber 122 , and the evaporator 80 is communicated with the condenser assembly 20 and the liquid storage tank 70 , respectively.

[0064] In detail, the evaporator 80 is arranged in the second chamber 122 and is spaced apart from the condenser assembly 20, which can reduce mutual interference between the two and simplify the circulation path of the refrigerant, so that the refrigerant can flow more smoothly from the condenser assembly 20 to the evaporator 80, and then return to the compressor 60 or the liquid storage tank 70.

[0065] The good connection between the evaporator 80, the condenser assembly 20 and the liquid storage tank 70 can ensure that the refrigerant can effectively absorb heat in the evaporator 80, thereby improving the cooling efficiency.

[0066] At the same time, placing the evaporator 80 in the second chamber 122 can make it easier to perform inspection and maintenance work.

[0067] In addition, an expansion valve (not shown) is connected between the evaporator 80 and the condenser assembly 20, so that the refrigerant flow rate can be controlled by adjusting the opening to ensure that the appropriate refrigerant pressure and temperature are always maintained in the evaporator 80, while preventing liquid refrigerant from entering the compressor 60 and causing a "liquid hammer" phenomenon.

[0068] In addition, an electrical box 90 is provided in the second chamber 122 to realize centralized management and control of various electrical components in the device.

[0069] 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 changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
