Technical Field

[0001] This utility model belongs to the field of oxygen generator technology, and in particular relates to an oxygen generator heat dissipation system and an oxygen generator. Background Technology

[0002] An oxygen generator is a machine used to produce oxygen through air separation technology. In the process of producing oxygen, the oxygen generator uses an air compressor as its working power to compress filtered and purified air. Then, using the adsorption properties of molecular sieves, nitrogen and oxygen in the air are separated, and the nitrogen and waste gas are discharged, while a high concentration of oxygen is retained, thus achieving oxygen production.

[0003] Currently, with the gradual expansion of market demand and the increasing maturity of oxygen concentrator manufacturing technology, small and portable oxygen concentrators have slowly entered various consumer sectors. Besides medical institutions and home healthcare, small medical oxygen concentrators are also widely used in various outdoor activities requiring supplemental oxygen, such as mountaineering and altitude sickness emergency care.

[0004] When the altitude of the environment exceeds 2,500 meters, the oxygen extraction efficiency of conventional oxygen generation systems will decrease significantly due to the reduced oxygen content in the air. Therefore, it is necessary to increase the number of compressors and increase the power of individual compressors to increase the overall working power of the oxygen generator. However, the increase in power causes the oxygen generator to generate more heat, which places higher demands on the heat dissipation function of the oxygen generator. Conventional oxygen generator architectures often cannot meet the heat dissipation requirements. Utility Model Content

[0005] The purpose of this application is to provide a heat dissipation system for an oxygen generator, which aims to solve the problems pointed out in the background art.

[0006] The embodiments of this application are implemented as follows: an oxygen generator heat dissipation system includes: Oxygen concentrator casing; A compressor housing is located inside the oxygen generator housing. The compressor housing contains a compressor assembly, and the top of the compressor housing has several array-type heat dissipation openings. An array-type heat dissipation assembly is disposed on the top of the compressor housing. The array-type heat dissipation assembly has several array-distributed air outlets that cooperate with the array-type heat dissipation openings, and multiple array-distributed air intakes; and A heat sink is disposed above the array-type heat dissipation assembly, and a portion of the channels of the compressor assembly are connected to the heat sink.

[0007] Preferably, the array-type heat dissipation component includes multiple array-arranged fan devices, and the multiple array-arranged fan devices correspond one-to-one with the array-distributed air outlets and the multiple array-distributed air inlets. The heat sink is suspended above the plurality of fan units by a support mechanism.

[0008] Preferably, the compressor assembly is a dual-cylinder compressor or uses a dual compressor, with the two cylinder heads of the compressor assembly arranged on the left and right sides and facing upwards, so as to be opposite to the array-type heat dissipation openings.

[0009] Preferably, the array-type heat dissipation assembly includes two sets of fan assemblies, one on the left and one on the right, wherein each set of fan assemblies includes two or three fan devices; each set of fan assemblies is opposite to the cylinder head of the compressor assembly on the corresponding side.

[0010] Preferably, the air intake axes of the fan devices in each fan assembly are parallel to each other and are arranged horizontally along the front-back direction of the oxygen generator.

[0011] Preferably, the oxygen generator heat dissipation system further includes a dual-intake silencer assembly, which includes two sets of intake silencers, and the two sets of intake silencers are respectively connected to an air inlet disposed on the oxygen generator housing; The two sets of intake silencers are respectively located on the left and right sides above the compressor housing, and together with the heat sink, they surround the array heat dissipation assembly in the middle.

[0012] Preferably, the oxygen generator heat dissipation system further includes a dual nitrogen exhaust silencing component, which comprises two sets of nitrogen exhaust silencing devices; Two sets of nitrogen exhaust silencers are located above the compressor housing and behind the array-type heat dissipation assembly. Together with the two sets of intake silencers and the heat dissipation plate, they surround the array-type heat dissipation assembly in the middle.

[0013] Preferably, the heat sink covers the middle part of the two sets of fan assemblies, and the front and rear ends of the heat sink extend beyond the front and rear end faces of the two sets of fan assemblies in the vertical projection direction.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0020] like Figures 1-5 As shown in the embodiment of this application, an oxygen concentrator heat dissipation system is provided, which includes: Oxygen concentrator casing 100; A compressor housing 200 is disposed inside the oxygen generator housing 100. A compressor assembly 300 is disposed inside the compressor housing 200. A plurality of array-type heat dissipation openings 210 are provided on the top of the compressor housing 200. An array-type heat dissipation assembly 400 is disposed on the top of the compressor housing 200. The array-type heat dissipation assembly 400 has a plurality of array-distributed air outlets (not shown) that cooperate with the array-type heat dissipation openings 210, and a plurality of array-distributed air intakes 420; and A heat sink 500 is disposed above the array-type heat dissipation assembly 400, and a portion of the compressed gas output channel 320 of the compressor assembly 300 is connected to the heat sink 500.

[0021] In this embodiment, the oxygen generator refers to an oxygen generator that uses pressure swing adsorption air separation oxygen generation technology, which includes core components such as a compressor assembly, an adsorption tower assembly, a heat dissipation assembly, and a noise reduction assembly; and this application mainly improves the heat dissipation system of the oxygen generator.

[0022] In this embodiment, as Figure 1 As shown, the side where the user panel 700 is located on the oxygen concentrator housing 100 is considered the front, and the opposite side is considered the rear. The left and right directions mentioned below are also based on this. The adsorption tower is located at the rear of the oxygen concentrator housing 100. The overall spatial layout of the front of the oxygen concentrator housing 100 is divided into upper and lower parts. The lower part contains the base and the compressor housing 200 located on the base, while the upper part contains the array-type heat dissipation assembly 400, the heat dissipation plate 500, and other related accessories.

[0023] In this embodiment, the connection between a portion of the compressed gas output channel 320 of the compressor assembly 300 and the heat sink 500 means that a portion of the compressed gas output channel 320 of the compressor assembly 300 is in contact with the heat sink 500, or the channel penetrates through the heat sink 500. Preferably, the heat sink 500 includes a finned heat dissipation structure, and a portion of the compressed gas output channel penetrates through the finned heat dissipation structure of the heat sink 500, and is arranged in a zigzag pattern on the heat dissipation structure; this arrangement increases the heat dissipation area of ​​the compressed gas output channel.

[0024] In this embodiment, the outlet temperature of a typical compressor assembly is relatively high, while the outlet temperature of a high-power compressor assembly is even higher and sustained. If heat dissipation is not timely and effective, the equipment will affect the normal operation of subsequent components (such as the adsorption tower) due to prolonged high-temperature operation. Simultaneously, the circuit boards and electronic components operate in an abnormally high-temperature environment, making them prone to malfunctions or even direct damage, leading to a reduced equipment lifespan. This embodiment enhances the heat dissipation efficiency of the oxygen concentrator for the compressor assembly 300 by using an array-type heat dissipation assembly. Simultaneously, a heat sink 500, in conjunction with the array-type heat dissipation assembly, cools the compressed gas output channel 320 of the compressor assembly 300, significantly improving the overall heat dissipation efficiency of the oxygen concentrator.

[0025] Specifically, the array-type heat dissipation component 400 is equipped with multiple array-distributed air outlets and multiple array-distributed air intakes 420, supporting large-area heat dissipation and high-power heat dissipation. The multiple array-distributed air outlets not only increase the heat dissipation points, but also effectively target the heat-generating parts of the compressor component 300 for heat dissipation, thereby improving the heat dissipation effect.

[0026] Furthermore, the array-type heat dissipation component 400 has multiple array-distributed air intakes 420. The heat dissipation plate 500 is placed above the array-type heat dissipation component 400. When the array-distributed air intakes 420 draw air from multiple positions and directions, airflow can be formed at multiple positions and directions. This airflow can flow through the heat dissipation plate 500 from multiple positions and directions and carry away the heat on the heat dissipation plate 500, which greatly improves the heat dissipation effect of the heat dissipation plate 500 on the compressed gas output channel 320.

[0027] As one embodiment of this application, such as Figure 3 As shown, the array-type heat dissipation assembly 400 includes a plurality of array-arranged fan devices 430, which correspond one-to-one with the array-distributed air outlets and the plurality of array-distributed air inlets 420; the heat dissipation plate 500 is suspended above the plurality of fan devices 430 by a support mechanism.

[0028] Understandably, each fan unit 430 includes an air outlet and an air inlet 420. Multiple fan units 430 arranged in an array form an array-type heat dissipation assembly 400, which includes multiple array-type air outlets and multiple array-type air inlets 420. The array-type heat dissipation openings 210 are used to connect with the air outlets of the fan units 430, thereby enabling the fan units 430 to blow air to dissipate heat from the compressor assembly 300 inside the compressor housing 200.

[0029] As one embodiment of this application, such as Figures 3-5As shown, the compressor assembly 300 is a dual-cylinder compressor or a combination of two compressors. The two cylinder heads 310 of the compressor assembly 300 are arranged side by side and face upwards, opposite the array-type heat dissipation opening 210. Regardless of whether a dual-cylinder compressor or a combination of two compressors is used, the goal is to provide greater air compression power, enabling the oxygen concentrator to operate in harsh working environments (such as environments with thin air or low oxygen content). Furthermore, the cylinder heads 310 of the compressor assembly 300 collect the gas to be output to the next stage, which is at a high temperature and is also the primary target for cooling. Therefore, to improve heat dissipation efficiency, the cylinder heads 310 of the compressor assembly 300 are positioned upwards, opposite the array-type heat dissipation opening 210 above. Combined with the heat dissipation plate 500, the compressed gas output channel 320 is further cooled, greatly improving the overall heat dissipation efficiency of the oxygen concentrator.

[0030] As one embodiment of this application, such as Figures 3-5 As shown, the array-type heat dissipation assembly 400 includes two sets of fan assemblies, each set containing two or three fan devices 430. Each set of fan assemblies corresponds to the cylinder head 310 of the compressor assembly 300 on the corresponding side. In this embodiment, the main heat dissipation parts of the dual-cylinder compressor or dual compressor are on its two cylinder heads 310. Therefore, the array-type heat dissipation assembly 400 is divided into two sets corresponding to them to improve heat dissipation efficiency. To avoid making the oxygen concentrator too large, while meeting the high-power operation requirements, the power of the compressor assembly 300 is controlled within a reasonable range, thereby matching the required number of fan devices to meet the heat dissipation needs. In this embodiment, four fans are preferred, which can ensure the heat dissipation requirements of a high-power compressor while keeping the compressor's size relatively portable.

[0031] When the preferred number of fans is 4, the 4 fan devices 430 can form a 2*2 array. The air inlets of the 4 fan devices 430 all face outwards to avoid mutual interference between the air intake of adjacent fan devices 430 as much as possible, and also to avoid the air intake of the fan devices 430 being obstructed by the heat sink 500 above.

[0032] As one embodiment of this application, the air intake axes of the fan devices 430 in each fan assembly are parallel to each other and are arranged horizontally along the front-back direction of the oxygen generator.

[0033] Understandably, the air inlet 420 of the fan device 430 is generally set as a cylinder, and the axis of this cylinder is the air inlet axis. The direction of the air inlet axis of the fan device 430 is arranged along the front and rear horizontal direction of the oxygen concentrator, which means that the air inlet axis of the fan device 430 is horizontal and parallel to the front and rear direction of the oxygen concentrator. Because the size of the fan device 430 in the direction of the air inlet axis is small, this arrangement can reduce the overall volume of the oxygen concentrator and make the structure more compact.

[0034] As one embodiment of this application, such as Figures 2-5 As shown, the oxygen generator heat dissipation system also includes a dual-intake silencing component, which includes two sets of intake silencing devices 610, and the two sets of intake silencing devices 610 are respectively connected to an air inlet provided on the oxygen generator housing 100. The two sets of intake silencers 610 are respectively located on the left and right sides above the compressor housing 200, and together with the heat sink 500, they surround the array heat sink 400 in the middle.

[0035] In this embodiment, a dual-intake muffler assembly is configured in the oxygen generator cooling system to match the intake volume requirements of a dual-cylinder compressor or a dual-compressor system, while reducing the intake noise of the compressor under high-power operation. Specifically, to enhance the intake airflow of the array-type cooling assembly 400 and thus improve its cooling effect on the heat dissipation plate 500, two sets of the intake mufflers 610 are arranged in a surrounding manner on the left and right sides of the array-type cooling assembly 400.

[0036] Furthermore, traditional oxygen concentrators are generally equipped with a single air intake silencer. However, when an oxygen concentrator is equipped with a more powerful compressor component, its air intake volume increases significantly, and therefore its air intake noise also increases greatly. In order to reduce noise, it is often necessary to add noise reduction medium (such as noise reduction cotton) to the air intake silencer. However, the noise reduction medium will generate a large air resistance. Combined with the already increased air intake volume, traditional oxygen concentrators cannot meet the air intake volume requirements of high-power compressor components at all.

[0037] In this embodiment, the intake requirements of the high-power compressor component are met by setting up dual intake channels and configuring dual intake silencers. It can be understood that both intake channels are equipped with intake silencers, which not only share the intake volume but also share the task of noise reduction. This effectively overcomes the problem that traditional single-intake silencers have high intake resistance and high intake noise when the compressor component power is high.

[0038] As one embodiment of this application, such as Figures 2-5 As shown, the oxygen generator heat dissipation system also includes a dual nitrogen exhaust silencing component, which comprises two sets of nitrogen exhaust silencing devices 620. Two sets of nitrogen exhaust silencers 620 are located above the compressor housing 200 and arranged behind the array-type heat dissipation assembly 400. Together with the two sets of intake silencers 610 and the heat dissipation plate 500, they surround the array-type heat dissipation assembly 400 in the middle.

[0039] In this embodiment, a dual nitrogen exhaust silencer assembly is configured in the oxygen generator cooling system to match the nitrogen exhaust requirements of a dual-cylinder compressor or a dual-compressor system, while reducing the nitrogen exhaust noise of the compressor under high-power operation. Specifically, to enhance the intake airflow of the array-type cooling assembly 400 and thus improve its cooling effect on the heat dissipation plate 500, two sets of nitrogen exhaust silencers 620 are positioned behind the array-type cooling assembly 400, working in conjunction with two sets of intake silencers 610 to form an enclosed enclosure around the array-type cooling assembly 400.

[0040] Furthermore, traditional oxygen concentrators are generally equipped with a single nitrogen exhaust silencer. However, when an oxygen concentrator is equipped with a more powerful compressor component, its nitrogen exhaust volume also increases significantly. As a result, its nitrogen exhaust noise also increases greatly. In order to reduce noise, it is often necessary to add noise reduction medium (such as noise reduction cotton) to the nitrogen exhaust silencer. However, the noise reduction medium will generate a large air resistance. Combined with the already increased nitrogen exhaust volume, traditional oxygen concentrators cannot meet the nitrogen exhaust volume requirements of high-power compressor components at all.

[0041] In this embodiment, the nitrogen discharge requirements of the high-power compressor component are met by setting up dual nitrogen discharge channels and configuring dual nitrogen discharge silencers. It can be understood that both nitrogen discharge channels are equipped with nitrogen discharge silencers, which not only share the task of exhaust volume but also the task of noise reduction. This effectively overcomes the problem that traditional single-nitrogen-discharge silencers have high nitrogen discharge resistance and noise when the compressor component power is high.

[0042] As one embodiment of this application, such as Figures 2-5 As shown, the heat sink 500 covers the middle part of the two sets of fan assemblies, and the front and rear ends of the heat sink 500 extend beyond the front and rear end faces of the two sets of fan assemblies in the vertical projection direction. In the vertical projection direction, at least one-third of the air intake 420 of each fan device 430 is located directly below the heat sink 500, and at least one-fifth of the air intake 420 is not located directly below the heat sink 500.

[0043] In this embodiment, the heat sink 500 covers the middle part of the two sets of fan components, but does not completely cover the left and right sides above the matrix heat sink components. The purpose is to leave a certain space on the left and right sides so that it forms an airflow passage between the two sets of air intake silencers 610 on the left and right sides and the two sets of nitrogen exhaust silencers 620 at the rear. This allows for a more obvious airflow to pass through both the left and right ends of the heat sink 500, thereby improving the heat dissipation efficiency of the left and right ends of the heat sink 500.

[0044] Furthermore, the front and rear ends of the heat sink 500 are directly opposite the air intake 420 of the fan device 430 in the projection direction. In order to improve the heat dissipation effect, the front and rear ends of the heat sink 500 are set to extend beyond the front and rear outer end faces of the two sets of fan components in the vertical projection direction. Due to the enclosure effect of the surrounding dual air intake silencer components, dual nitrogen exhaust silencer components, and the oxygen generator housing 100 at the front, the part of the heat sink 500 that extends beyond the front and rear outer end faces of the fan components will be subjected to a large upward and downward airflow "scouring" during the air intake process. To ensure adequate heat dissipation at both ends of the heat sink 500, a portion of space needs to be provided in the projection direction of the heat sink 500. This allows some airflow to be drawn into the air intake 420 of the fan device 430 from the upper side, creating an airflow "scouring" effect on the left and right sides of the heat sink 500. Therefore, in the vertical projection direction, at least one-third of the air intake 420 of each fan device 430 is located directly below the heat sink 500, and at least one-fifth of the air intake 420 is not located directly below the heat sink 500. This ensures sufficient airflow at the front and rear ends of the heat sink 500 while also supplementing the airflow scouring effect at the left and right ends, resulting in a more balanced overall heat dissipation effect and higher heat dissipation efficiency for the heat sink 500.

[0045] In one embodiment of this application, an oxygen generator is also provided, which includes the oxygen generator heat dissipation system described in any of the above embodiments.

[0046] The oxygen concentrator provided in the above embodiments of this application includes an array-type heat dissipation component with multiple array-distributed air outlets and multiple array-distributed air inlets in its heat dissipation system, and a heat dissipation plate disposed above the array-type heat dissipation component. A portion of the compressed gas output channel of the compressor component is connected to the heat dissipation plate. The multiple array-distributed air outlets and air inlets of the array-type heat dissipation component can support large-area heat dissipation and high-power heat dissipation. The multiple array-distributed air outlets not only increase the heat dissipation points but also effectively target the heat-generating parts of the compressor component, thereby improving the heat dissipation effect. Furthermore, the array-type heat dissipation component has multiple array-distributed air inlets. With the heat dissipation plate disposed above the array-type heat dissipation component, when the array-distributed air inlets draw air from multiple positions and directions, airflow can be formed at multiple positions and directions. This airflow can flow through the heat dissipation plate from multiple positions and directions, carrying away the heat on the heat dissipation plate and greatly improving the heat dissipation effect of the heat dissipation plate on the compressed gas output channel.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
