Key components of PSA systems include air compressors and controllers, which are prone to generating significant amounts of heat over extended periods, thus affecting oxygen quality and efficiency.

[0003] In existing technologies, heat dissipation for the aforementioned heat-generating components typically relies on air-cooling or water-cooling systems. While these cooling methods effectively reduce the operating temperature of heat-generating components, their energy consumption is relatively high, especially during continuous operation or in high-temperature environments, where energy consumption of the cooling system increases significantly, thereby raising the overall system operating costs. Furthermore, traditional cooling methods often come with increased maintenance costs, such as the need for regular cleaning of cooling fans or replacement of coolant, which adds an additional burden. Utility Model Content

[0004] The main objective of this invention is to provide an oxygen generating device and an air conditioner having the same, in order to solve the problem that the heat dissipation method for the heating components in existing oxygen generating devices is costly.

[0005] To achieve the above objectives, according to one aspect of the present invention, an oxygen generating device is provided, comprising: a molecular sieve component for separating oxygen and nitrogen; and a nitrogen venting component connected to the molecular sieve component, wherein the nitrogen venting component is provided with a nitrogen venting channel, and the nitrogen outlet of the nitrogen venting channel is disposed toward the component to be cooled, so that the nitrogen blown out through the nitrogen venting channel cools the component to be cooled.

[0006] Furthermore, the component to be cooled includes an air compressor assembly; at least a portion of the nitrogen outlet of the nitrogen venting channel is positioned toward the air compressor assembly so that nitrogen in the nitrogen venting channel is blown toward the air compressor assembly to cool the air compressor assembly.

[0007] Furthermore, the air compressor assembly includes: an air compressor in communication with the molecular sieve component; a mounting housing, in which the air compressor is disposed, at least a portion of the nitrogen venting component extends into the mounting housing, and the nitrogen outlet of the nitrogen venting channel is oriented toward the air compressor so that nitrogen is blown toward the surface of the air compressor to dissipate heat from the air compressor.

[0008] Furthermore, an extension body is provided on the mounting housing, extending from the mounting housing toward the direction of the nitrogen venting component; an installation channel is provided inside the extension body, and at least a portion of the nitrogen venting component is disposed within the installation channel, so that nitrogen gas is blown into the surface of the air compressor through the nitrogen outlet through the installation channel.

[0009] Furthermore, the oxygen generating device also includes a sealing component disposed between the installation channel and the nitrogen venting component. The sealing component is respectively fitted to the installation channel and the nitrogen venting component to seal the gap between the installation channel and the nitrogen venting component.

[0010] Furthermore, the components to be cooled include a controller, a molecular sieve component, and a nitrogen venting component, which are respectively connected to the controller; at least a portion of the nitrogen outlet of the nitrogen venting channel is positioned facing the controller so that nitrogen is blown onto the surface of the controller to cool it.

[0011] Furthermore, the component to be cooled also includes an air compressor assembly; the nitrogen outlet includes a first outlet and a second outlet, the first outlet being disposed toward the air compressor assembly and the second outlet being disposed toward the controller.

[0012] Furthermore, the controller is located on the side of the air compressor assembly; the nitrogen venting component includes a nitrogen venting end face and a nitrogen venting side face connected to each other, with a first outlet located on the nitrogen venting end face and a second outlet located on the nitrogen venting side face.

[0013] Furthermore, there are multiple first outlets, which are spaced apart on the nitrogen venting end face; and / or, there are multiple second outlets, which are spaced apart on the nitrogen venting side face.

[0014] According to another aspect of the present invention, an air conditioner is provided, including an outdoor unit and an oxygen generating device, wherein the oxygen generating device is disposed in the outdoor unit and is the oxygen generating device described above.

[0015] Furthermore, the outdoor unit includes a first installation space and a second installation space. The oxygen generating device is installed in the first installation space.

The second installation space is connected to the air compressor assembly of the oxygen generating device, so that the nitrogen in the air compressor assembly flows through the air compressor assembly and the second installation space under the guidance of the axial flow fan and is then discharged from the outdoor unit.

[0016] The oxygen generator, utilizing the technical solution of this invention, includes a molecular sieve component and a nitrogen purging component. The molecular sieve component separates oxygen and nitrogen. The nitrogen purging component is connected to the molecular sieve component and contains a nitrogen purging channel. The nitrogen outlet of the nitrogen purging channel faces the component to be cooled, allowing the nitrogen blown out through the channel to dissipate heat from the component. This nitrogen purging channel design allows the low-pressure nitrogen generated during molecular sieve desorption to be directly used for cooling the component, eliminating the need for additional energy input.

[0019] This application combines nitrogen removal and heat dissipation functions, achieving efficient integration and utilization of resources. It reflects the wisdom of the design and the pursuit of overall system optimization, thereby improving the performance and energy-saving and emission-reduction effects of the oxygen generation device.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] As mentioned in the background section, key components in existing oxygen generators include air compressors and controllers, which are prone to generating significant heat over extended periods, impacting oxygen quality and efficiency. Current solutions typically rely on air or water cooling systems to dissipate heat from these heat-generating components. While these methods effectively reduce the operating temperature of the heat-generating components, their energy consumption is relatively high, especially during continuous operation or in high-temperature environments, significantly increasing the overall system operating costs. Furthermore, traditional cooling methods often involve increased maintenance costs, such as the need for regular cleaning of cooling fans or replacement of coolant, adding an additional burden. Therefore, to address these technical problems, the oxygen generator provided in this application directs the nitrogen outlet 220 of the nitrogen venting channel 210 towards the component to be cooled, using nitrogen blown out through the venting channel 210 to dissipate heat from the component. Compared to traditional air or water cooling systems, this application utilizes nitrogen, a byproduct of the oxygen generation process, as the cooling medium, eliminating the need for additional energy consumption to drive cooling fans or circulate coolant, thus significantly reducing system energy consumption while ensuring effective heat dissipation. Over the long term, this energy-saving effect will translate into a significant reduction in operating costs. Traditional cooling systems require regular maintenance, such as cleaning fans or replacing coolant, while using nitrogen as a cooling medium reduces the need for direct maintenance of heat dissipation components due to nitrogen's cleanliness, thus lowering maintenance costs and workload and making the system simpler and more reliable to operate.

[0034] Please refer to Figures 1 to 3This application provides an oxygen generating device, including: a molecular sieve component 100 for separating oxygen and nitrogen; and a nitrogen venting component 200 connected to the molecular sieve component 100. The nitrogen venting component 200 is provided with a nitrogen venting channel 210, and the nitrogen outlet 220 of the nitrogen venting channel 210 is arranged facing the component to be cooled, so that the nitrogen blown out through the nitrogen venting channel 210 can cool the component to be cooled.

[0035] The oxygen generating device provided in this application includes a molecular sieve component 100 and a nitrogen removal component 200. The molecular sieve component 100 is used to separate oxygen and nitrogen. The nitrogen removal component 200 is connected to the molecular sieve component 100 and has a nitrogen removal channel 210. The nitrogen outlet 220 of the nitrogen removal channel 210 is oriented towards the component to be cooled, so that the nitrogen blown out through the nitrogen removal channel 210 can dissipate heat from the component. The design of the nitrogen removal channel 210 allows the low-pressure nitrogen generated during the molecular sieve desorption process to be directly used for cooling the component, without the need for additional energy input, which greatly reduces cooling costs and improves the energy efficiency ratio of the entire oxygen generating system, especially under continuous operation, where the energy-saving effect is particularly significant.

[0036] The cooling and purging effects of nitrogen help reduce performance degradation and failure rates of components that need to be cooled due to overheating, extend the service life of equipment, and reduce downtime and economic losses caused by equipment damage.

[0037] Nitrogen, as a clean and dry gas, can effectively remove dust and moisture accumulated on the surface of the components to be cooled when it is blown through the nitrogen purging channel 210. This reduces the frequency of regular cleaning and maintenance of these components, while also easing the pressure on the cooling system and lowering the overall maintenance cost.

[0038] This application combines nitrogen removal and heat dissipation functions, achieving efficient integration and utilization of resources. It reflects the wisdom of the design and the pursuit of overall system optimization, thereby improving the performance and energy-saving and emission-reduction effects of the oxygen generation device.

[0039] Specifically, the component to be cooled includes an air compressor assembly 300; at least a portion of the nitrogen outlet 220 of the nitrogen venting channel 210 is disposed toward the air compressor assembly 300 so that the nitrogen in the nitrogen venting channel 210 is blown toward the air compressor assembly 300 to cool the air compressor assembly 300.

[0040] Air compressors generate a significant amount of heat during operation, especially in their compression cylinder. Using nitrogen as a heat dissipation medium allows for precise control of nitrogen flow, ensuring that heat is rapidly dissipated from the hottest parts of the compressor, thus maintaining its operating temperature within an ideal range. This not only improves the compressor's efficiency but also reduces the equipment failure rate caused by overheating.

[0041] Traditional heat dissipation methods, such as air cooling or water cooling systems, are effective in heat dissipation, but they come with high energy consumption and water resource usage. This application utilizes nitrogen generated during the oxygen production process for heat dissipation, requiring no additional energy input, reducing the energy consumption of the cooling system, and also avoiding water waste, reflecting the concept of environmentally friendly and sustainable heat exchange in the equipment design.

[0042] Nitrogen has a certain flow rate and cleaning properties. When it is blown towards the air compressor through the nitrogen venting channel 210, it not only carries away heat, but also effectively blows away dust and impurities inside and outside the air compressor, preventing these particles from entering the compression cylinder, reducing wear, and extending the service life of the air compressor and its related components.

[0043] By utilizing the natural properties of nitrogen for heat dissipation, this method avoids the need for complex coolant circulation structures or high-power fans compared to traditional cooling systems, thus reducing system complexity and maintenance difficulty. It also reduces the maintenance cycle and cost of the cooling system and improves the operational stability of the equipment.

[0044] In the specific implementation process, the air compressor assembly 300 includes: an air compressor 310, which is connected to the molecular sieve component 100; a mounting housing 320, in which the air compressor 310 is disposed, at least a portion of the nitrogen venting component 200 extends into the mounting housing 320, and the nitrogen outlet 220 of the nitrogen venting channel 210 is disposed facing the air compressor 310 so that nitrogen is blown onto the surface of the air compressor 310 to dissipate heat from the air compressor 310.

[0045] Air compressor 310 generates a large amount of heat during the air compression process, causing the temperature to rise and affecting compression efficiency and equipment lifespan. Nitrogen gas is introduced to air compressor 310 through nitrogen venting channel 210. The flow of nitrogen gas can carry away heat, achieving direct cooling of the air compressor and helping to maintain it within the optimal operating temperature range, thereby improving overall performance.

[0046] Using nitrogen as a cooling medium can replace or reduce the use of traditional air-cooled or water-cooled systems, thus reducing the energy consumption of the cooling system. Nitrogen, as a byproduct, is already produced in the oxygen production process, requiring no additional energy or water resources, thereby achieving energy reuse and reducing the operating costs of the oxygen production unit.

[0047] Nitrogen purging effectively removes dust and impurities from the surface of the air compressor 310, reducing performance degradation and maintenance frequency caused by contaminant accumulation. Simultaneously, the cooling effect of nitrogen reduces the possibility of overheating, further extending the equipment's lifespan and lowering maintenance costs.

[0048] Nitrogen is an inert gas that is non-flammable and non-explosive. Introducing nitrogen into the mounting housing 320 of the air compressor 310 can create a relatively closed and low-oxygen environment, reducing the risk of fire caused by high temperature in the air compressor and enhancing the safety and reliability of the system.

[0049] Furthermore, an extension body 321 is provided on the mounting housing 320, and the extension body 321 extends from the mounting housing 320 toward the direction of approaching the nitrogen venting component 200; an installation channel 322 is provided inside the extension body 321, and at least a portion of the nitrogen venting component 200 is provided in the installation channel 322, so that nitrogen gas is blown into the surface of the air compressor 310 through the nitrogen outlet 220 outlet and the installation channel 322.

[0050] By placing a portion of the nitrogen venting component 200 within the mounting channel 322, it is ensured that nitrogen gas, after being blown out from the nitrogen outlet 220, is directly and effectively blown onto the surface of the air compressor 310, achieving precise control over the air compressor's heat dissipation. This design avoids energy loss of nitrogen gas during transmission, improves heat dissipation efficiency, and thus ensures the stability and performance of the air compressor during long-term operation.

[0051] The extension design of the extended body 321 toward the nitrogen venting component 200 not only makes reasonable use of the space of the mounting housing 320, but also minimizes the distance between the nitrogen venting component 200 and the air compressor 310, simplifying the system structure and enhancing the overall integration and compactness.

[0052] When nitrogen gas is blown onto the surface of the air compressor 310 through the installation channel 322, it not only carries away heat but also has a cleaning effect. It helps to remove dust, moisture and other impurities from the surface of the air compressor and the surrounding environment, improves the environmental quality of equipment operation, reduces equipment wear and failures caused by environmental pollution, and thus extends the service life of the air compressor and its related components.

[0053] Furthermore, the oxygen generating device also includes a sealing component disposed between the installation channel 322 and the nitrogen venting component 200. The sealing component is respectively fitted to the installation channel 322 and the nitrogen venting component 200 to seal the gap between the installation channel 322 and the nitrogen venting component 200.

[0054] The sealing component effectively blocks the airflow between the installation channel 322 and the nitrogen venting component 200, ensuring that nitrogen does not leak during the process of blowing onto the surface of the air compressor 310, maintaining the stability of nitrogen flow and pressure, thereby ensuring the efficiency and effect of heat dissipation and providing a guarantee for the stable operation of the air compressor.

[0055] By sealing the gaps, dust, moisture, and other potentially harmful substances from the outside can be isolated, protecting the air compressor and nitrogen exhaust components 200 from the influence of the external environment, reducing equipment failures and safety hazards caused by foreign object intrusion, and improving the safety level of the entire oxygen generation unit.

[0056] The sealing component can also effectively reduce the noise when nitrogen flows out through the gap between the nitrogen venting component 200 and the installation channel 322, and ensure the sealing performance between the two through the sealing component.

[0057] The components to be cooled include a controller 500, a molecular sieve component 100, and a nitrogen venting component 200, which are respectively connected to the controller 500. At least a portion of the nitrogen outlet 220 of the nitrogen venting channel 210 is positioned toward the controller 500 so that nitrogen is blown toward the surface of the controller 500 to cool the controller 500.

[0058] As a core component of the oxygen generation system, the controller 500's internal electronic components are sensitive to temperature. By using nitrogen to dissipate heat, the controller's operating temperature can be effectively controlled, preventing performance degradation or failure of electronic components due to high temperatures, thus ensuring the controller's long-term stable operation.

[0059] Traditional heat dissipation methods can increase the risk of fire due to controller operation in high-temperature environments. Nitrogen, as an inert gas, is non-flammable and does not support combustion. Using it for heat dissipation can significantly reduce the fire hazard in the area where the controller is located, thus improving the safety performance of the entire oxygen generation system.

[0060] The high-speed flow of nitrogen can also blow away dust and impurities from the controller surface, keeping it clean, which helps optimize signal transmission efficiency, reduce system failures caused by poor contact, and further improve the reliability and efficiency of the equipment.

[0061] In the specific implementation process, the component to be cooled also includes an air compressor assembly 300; the nitrogen outlet 220 includes a first outlet 221 and a second outlet 222, the first outlet 221 is set toward the air compressor assembly 300, and the second outlet 222 is set toward the controller 500.

[0062] The first outlet 221 directly dissipates heat from the air compressor assembly 300, effectively reducing the high temperature during air compressor operation and improving its operational stability and efficiency. Simultaneously, the second outlet 222 cools the controller 500, preventing controller malfunction due to overheating, ensuring normal controller operation, and enhancing the reliability of the entire system.

[0063] By using nitrogen gas simultaneously for cooling both the air compressor component 300 and the controller 500, the nitrogen gas, a byproduct of the oxygen production process, is fully utilized, avoiding resource waste. Compared to a separate cooling system, this integrated design significantly reduces energy consumption, achieving the goals of energy conservation and emission reduction.

[0064] Nitrogen, as a dry and clean gas, effectively removes dust and moisture from the surfaces of the air compressor and controller through purging via the first outlet 221 and the second outlet 222, reducing equipment wear and corrosion caused by environmental factors. This not only reduces maintenance frequency and costs but also extends the equipment's lifespan.

[0065] Controller 500 may be in a high-oxygen environment due to oxygen leakage, increasing the risk of component oxidation and sparking. The second outlet 222 uses nitrogen purging, which reduces the oxygen concentration around the controller, providing fire and explosion protection and significantly improving the overall system safety.

[0066] The controller 500 is located on the side of the air compressor assembly 300; the nitrogen venting component 200 includes a nitrogen venting end face 201 and a nitrogen venting side face 202 connected to each other, a first outlet 221 is provided on the nitrogen venting end face 201, and a second outlet 222 is provided on the nitrogen venting side face 202.

[0067] The design of the positions of the first outlet 221 and the second outlet 222 ensures that nitrogen gas can be precisely blown onto the surfaces of the air compressor and the controller, respectively, achieving directional cooling of different components, avoiding ineffective dispersion of heat dissipation resources, and improving the efficiency and targeting of nitrogen heat dissipation.

[0068] The differentiated design of placing the controller 500 on the side of the air compressor assembly 300, and the nitrogen discharge end face 201 and nitrogen discharge side face 202 of the nitrogen discharge component 200, not only saves space but also makes the equipment layout more reasonable, enhances the overall integration and compactness, and helps the equipment to be miniaturized and modularized.

[0069] By directly applying nitrogen to critical heat dissipation components of the equipment, reliance on traditional cooling equipment is reduced, thus lowering system energy consumption. As a byproduct of the oxygen production process, the reuse of nitrogen not only reduces energy waste but also lowers the operating costs of the cooling system, achieving the system's energy-saving and consumption-reducing goals.

[0070] The nitrogen venting side 202 blows nitrogen gas toward the controller 500, providing additional fire protection for the controller. The inert properties of nitrogen effectively reduce the oxygen concentration in the environment around the controller, reducing the risk of fire caused by high temperatures or electrical faults.

[0071] There are multiple first outlets 221, and the multiple first outlets 221 are spaced apart on the nitrogen discharge end face 201; and / or, there are multiple second outlets 222, and the multiple second outlets 222 are spaced apart on the nitrogen discharge side face 202.

[0072] The multiple outlet design allows nitrogen to be distributed more evenly onto the surfaces to be cooled, especially on the surfaces of the air compressor assembly 300 and the controller 500. The spaced outlets ensure that nitrogen can form a stable airflow at critical parts of these components, improving heat dissipation efficiency, effectively dispersing and removing heat evenly, and preventing localized overheating.

[0073] By adjusting the number and spacing of different outlets, the flow direction and flow rate of nitrogen can be flexibly controlled according to actual working conditions to adapt to different heat dissipation requirements. This design flexibility allows the system to better cope with temperature changes in the air compressor and controller under different loads, ensuring the stability and safety of the equipment under various operating conditions.

[0074] like Figure 4 and Figure 5 As shown, this application also provides an air conditioner, including an outdoor unit 600 and an oxygen generator 700, wherein the oxygen generator 700 is disposed inside the outdoor unit 600, and the oxygen generator 700 is the oxygen generator 700 of the above embodiment.

[0075] The outdoor unit 600 includes a first installation space 601 and a second installation space 602. The oxygen generating device 700 is disposed in the first installation space 601. The air conditioner also includes an axial flow fan 800 disposed in the second installation space 602. The second installation space 602 is connected to the air compressor assembly 300 of the oxygen generating device 700, so that the nitrogen in the air compressor assembly 300 is discharged from the outdoor unit 600 after flowing through the air compressor assembly 300 and the second installation space 602 under the guidance of the axial flow fan 800.

[0076] When the oxygen generator 700 operates in the first installation space 601, the generated nitrogen gas is guided by the axial flow fan 800 to the second installation space 602 and then discharged, achieving effective heat dissipation for the air compressor. This thermal management strategy ensures a balanced internal temperature for the air conditioner, avoids the impact of localized overheating on air conditioning performance, and improves the overall efficiency and operational stability of the air conditioner.

[0077] By using nitrogen, a byproduct of the oxygen production process, for heat exchange inside the air conditioner, the traditional air-cooled or liquid-cooled heat dissipation method is replaced, reducing the energy consumption of additional cooling equipment.

[0078] The controller 500 of the oxygen generator 700 is located in a high-oxygen environment, posing a certain fire hazard. Through the axial flow fan 800, nitrogen can be directed to cover the controller 500, creating a safe low-oxygen environment. This significantly reduces the risk of fire caused by overheating of components and improves system safety.

[0079] Compared to traditional fan or motor cooling methods, the axial fan 800 combined with nitrogen circulation effectively reduces operating noise, creating a quieter and more comfortable user environment and improving the user experience.

[0080] The oxygen generator 700 also includes an oxygen storage tank 900. The oxygen separated by the molecular sieve component 100 is introduced into the oxygen storage tank 900, where the oxygen is stored and then introduced into the indoor unit.

[0081] Specifically, the oxygen generation system discharges a large amount of nitrogen during the adsorption-desorption cycle. Nitrogen is discharged through the molecular sieve four-way valve, silenced by a silencer 400, and then discharged to the oxygen controller and air compressor chamber via a nitrogen venting component 200. ① The temperature of the discharged nitrogen generally does not exceed 40℃, and its velocity will result in an even lower temperature. The air compressor operating temperature is generally 70-100℃. Using an axial flow fan with negative pressure 800, nitrogen can quickly pass through the air compressor to dissipate heat and simultaneously purge the compressor, preventing dust from entering the compressor cylinder. ② Nitrogen is an inert gas. The controllers (including the oxygen controller and outdoor unit controller) may be in a high-oxygen environment due to oxygen leakage, which can easily cause oxidation or sparking of components, creating a combustion safety hazard. The nitrogen venting protects the controller, and the velocity of the discharged nitrogen can also purge dust from the controller, eliminating the need for a controller cover and reducing costs.

[0082] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0083] The oxygen generating device provided in this application includes a molecular sieve component 100 and a nitrogen removal component 200. The molecular sieve component 100 is used to separate oxygen and nitrogen. The nitrogen removal component 200 is connected to the molecular sieve component 100 and has a nitrogen removal channel 210. The nitrogen outlet 220 of the nitrogen removal channel 210 is oriented towards the component to be cooled, so that the nitrogen blown out through the nitrogen removal channel 210 can dissipate heat from the component. The design of the nitrogen removal channel 210 allows the low-pressure nitrogen generated during the molecular sieve desorption process to be directly used for cooling the component, without the need for additional energy input, which greatly reduces cooling costs and improves the energy efficiency ratio of the entire oxygen generating system, especially under continuous operation, where the energy-saving effect is particularly significant.

[0084] The cooling and purging effects of nitrogen help reduce performance degradation and failure rates of components that need to be cooled due to overheating, extend the service life of equipment, and reduce downtime and economic losses caused by equipment damage.

[0085] Nitrogen, as a clean and dry gas, can effectively remove dust and moisture accumulated on the surface of the components to be cooled when it is blown through the nitrogen purging channel 210. This reduces the frequency of regular cleaning and maintenance of these components, while also easing the pressure on the cooling system and lowering the overall maintenance cost.

[0086] This application combines nitrogen removal and heat dissipation functions, achieving efficient integration and utilization of resources. It reflects the wisdom of the design and the pursuit of overall system optimization, thereby improving the performance and energy-saving and emission-reduction effects of the oxygen generation device.
