Abstract
Description
Technical Field
[0001] This application relates to the field of air compression technology, and in particular to scroll compressors and oxygen generation equipment. Background Technology
[0002] Compressed air plays a crucial role as a power source in numerous fields, including industrial production, medical equipment, and food processing. The working principle of an oil-free scroll air compressor primarily involves compressing air through the rotational motion of a scroll. The equipment contains a fixed scroll and an eccentrically rotating scroll driven by a motor. During operation, the scroll creates a cavitation with gradually changing volume. When air enters, the cavitation expands and contracts, thus generating compressed air. Because it does not use lubricating oil, the oil-free scroll compressor provides pure compressed air, fundamentally avoiding the impact of oil contamination on product quality. This is particularly important for industries with extremely high air quality requirements, such as medical, food, and electronics manufacturing. It is especially suitable for applications with stringent air quality requirements, such as oxygen concentrators, ventilators, and dental equipment. The oil-free scroll compressor provides pure, pollution-free compressed air, ensuring the safety and stability of medical procedures.
[0003] Because there are many high-speed friction pairs inside the scroll compressor, a lot of heat is generated. Therefore, oil-free scroll compressors have high requirements for heat dissipation. Water cooling is usually used to dissipate heat from oil-free scroll compressors. However, because there are many parts that need heat exchange, the current water cooling method requires multiple heat exchange devices, which is costly and energy-intensive. Utility Model Content

[0095] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0096] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0097] Oil-free scroll compressors are a new type of high-efficiency fluid machinery with broad application prospects and market potential in various fields such as gas compression, refrigeration, air conditioning, engine turbocharging, and booster pumps. A scroll compressor consists of a fixed scroll plate composed of one or more profiles and a matching eccentrically rotating and translating moving scroll plate, forming a compressor capable of compressing volume. The fixed scroll plate is usually called the stationary scroll plate, and the eccentrically rotating and translating moving scroll plate is called the moving scroll plate. Under the action of a transmission mechanism, the moving scroll plate performs translational motion. During this translational motion, the moving scroll plate and the stationary scroll plate form multiple compression chambers with continuously changing volumes, thereby compressing air to produce compressed gas.
[0098] Because oil-free scroll compressors have many high-speed friction pairs inside, such as the moving scroll and stationary scroll, crankshaft and bearing, moving scroll and housing, and crankshaft and housing, these high-speed friction pairs, combined with the heat generated during air compression, will cause the scroll plate to heat up. Since the strength and elastic limit of the scroll plate metal decrease with increasing temperature, high temperature and severe deformation will cause the moving parts inside the compression chamber to interfere with each other, generating vibration and noise, reducing the compressed gas pressure, increasing gas leakage, and even reducing the life of the scroll compressor.
[0099] Oil-free scroll compressors are typically cooled by water. However, due to the numerous components requiring heat exchange, current water cooling methods necessitate multiple heat exchange devices, resulting in high costs and energy consumption. Specifically, an oil-free scroll compressor requires at least two sets of heat exchange equipment: one for water cooling the stationary scroll and the other for water cooling the motor housing. Currently, the cooling method for oil-free scroll compressors involves using separate heat exchange devices to cool the stationary scroll and the motor housing. The water cooling processes for the stationary scroll and the motor housing are independent and do not interfere with each other, leading to high costs and energy consumption in the heat exchange equipment of oil-free scroll compressors.
[0100] Based on this, this application provides a scroll compressor in which the heat exchange channels of the stationary scroll and the motor housing are interconnected. Therefore, the same set of heat exchange equipment can be used to cool the stationary scroll and the motor housing at the same time, thereby reducing water cooling costs and water cooling operation energy consumption.
[0101] This application provides a scroll compressor. In one embodiment, refer to... Figures 1 to 3 , Figure 1 This is an axial cross-sectional schematic diagram of an embodiment of the scroll compressor provided in this application. Figure 2 yes Figure 1 A three-dimensional structural diagram of a scroll compressor. Figure 3 yes Figure 2 The schematic diagram shows a scroll compressor 100, which includes a stationary scroll 110, a moving scroll 120, a motor 150, and a housing 130. One end of the housing 130 is connected to the stationary scroll 110. The moving scroll 120 and the motor 150 are respectively housed within the housing 130. One end of the moving scroll 120 meshes with the stationary scroll 110, and the motor 150 is connected to the other end of the moving scroll 120. The stationary scroll 110 is provided with a first heat exchange channel 101, one end of which is provided with a first channel opening 101A. The housing 130 is provided with a second heat exchange channel 102, one end of which is connected to the end of the first heat exchange channel 101 away from the first channel opening 101A, and the other end of the second heat exchange channel 102 is provided with a second channel opening 102A.
[0102] Among them, the stationary scroll 110 and the moving scroll 120 are the main components of the scroll compressor 100 that realize the gas compression function. One end of the moving scroll 120 meshes with the stationary scroll 110, and the two form a compression chamber 1112 for compressing gas. The eccentric rotation of the moving scroll 120 relative to the stationary scroll 110 can make the closed volume of the compression chamber 1112 formed between the moving scroll 120 and the stationary scroll 110 continuously change, thereby compressing the low-pressure gas drawn into the compression chamber 1112 into high-pressure gas and discharging it.
[0103] The motor 150 drives the moving scroll 120 to rotate eccentrically relative to the stationary scroll 110. The housing 130 surrounds the motor 150 to protect it from external damage. For example, the motor 150 is connected to a crankshaft 160, which passes through the housing 130 and connects to the moving scroll 120. The motor 150 drives the crankshaft 160 to rotate, thereby driving the moving scroll 120 to translate relative to the stationary scroll 110. Here, the translation of the moving scroll 120 relative to the stationary scroll 110 means that the moving scroll 120 only revolves around the stationary scroll 110 without rotating on its own axis.
[0104] Typically, the motor 150 may include a stator 151 and a rotor 152. The stator 151 is fixed to the inner wall of the housing 130 and sleeved around the rotor 152. The crankshaft 160 passes through the rotor 152 and is fixedly connected to it. By supplying power to the stator coils of the stator 151, the stator coils of the stator 151 generate an electromagnetic effect with the magnets of the rotor 152, thereby causing the rotor 152 to rotate relative to the stator 151. When the rotor 152 rotates, it synchronously drives the crankshaft 160 to rotate.
[0105] In some embodiments, in order to achieve smooth rotation of the crankshaft 160, the end of the crankshaft 160 away from the rotor 152 extends to the connected moving scroll 120.
[0106] In some embodiments, in order to achieve axial support for the crankshaft 160 and smooth rotation of the crankshaft 160, a plurality of bearings are typically fitted on the crankshaft 160. For example, it may include a first crankshaft bearing 161, a second crankshaft bearing 162 and a third crankshaft bearing 163. The second crankshaft bearing 162 and the third crankshaft bearing 163 are respectively located at both ends of the crankshaft 160, and the first crankshaft bearing 161 is located between the second crankshaft bearing 162 and the third crankshaft bearing 163. The outer ring of the first crankshaft bearing 161 can be fixed to the end of the housing 130 facing the moving scroll 120, the outer ring of the second crankshaft bearing 162 can be fixed to the side of the moving scroll 120 away from the stationary scroll 110, and the outer ring of the third crankshaft bearing 163 can be fixed to the end of the housing 130 away from the moving scroll 120. Thus, the crankshaft 160 can rotate smoothly relative to the housing 130 through the first crankshaft bearing 161, the second crankshaft bearing 162, and the third crankshaft bearing 163, thereby driving the moving scroll 120 to move smoothly relative to the stationary scroll 110.
[0107] As the gas is compressed by the eccentric rotation of the moving scroll 120 relative to the stationary scroll 110, the gas pressure and temperature increase simultaneously. The heat is conducted to the stationary scroll 110, causing its temperature to rise as well. At the same time, the motor 150 also generates a large amount of heat when it is working. The heat generated by the motor 150 is transferred to the housing 130, causing its temperature to rise as well.
[0108] In this embodiment of the application, the first heat exchange channel 101 provided in the stationary vortex disk 110 is used for the flow of heat exchange medium. The heat exchange medium flowing through the first heat exchange channel 101 can exchange heat with the stationary vortex disk 110. The heat of the stationary vortex disk 110 can be transferred to the heat exchange medium flowing in the first heat exchange channel 101. As the heat exchange medium flows out, it carries away the heat of the stationary vortex disk 110, thereby achieving the cooling of the stationary vortex disk 110.
[0109] In this embodiment, the second heat exchange channel 102 provided in the shell 130 is used for the flow of heat exchange medium. The heat exchange medium flowing through the second heat exchange channel 102 can exchange heat with the shell 130. The heat of the shell 130 can be transferred to the heat exchange medium in the second heat exchange channel 102. As the heat exchange medium flows out, it carries away the heat of the shell 130, thereby achieving cooling of the shell 130.
[0110] Furthermore, since the first heat exchange channel 101 is connected to the second heat exchange channel 102, the first channel port 101A at one end of the first heat exchange channel 101 and the second channel port 102A at one end of the second heat exchange channel 102 are respectively used to connect the inlet 100A and the outlet 100B. For example, the first channel port 101A can be connected to the inlet 100A, and the second channel port 102A can be connected to the outlet 100B. The heat exchange medium entering from the inlet 100A can flow through the first heat exchange channel 101 and the second heat exchange channel 102 in sequence to cool the stationary vortex plate 110 and the shell 130, and then the heat exchange medium flows out from the outlet 100B.
[0111] The heat exchange medium involved in the embodiments of this application can be water, or other types of liquid or gaseous fluids. The heat exchange medium can be provided by an external heat exchange device, which provides the heat exchange medium to flow in from inlet 100A and out from outlet 100B.
[0112] The scroll compressor 100 provided in this application embodiment includes a stationary scroll 110, a moving scroll 120, a motor 150, and a housing 130. The motor 150 drives the moving scroll 120 to rotate eccentrically relative to the stationary scroll 110, thereby changing the volume of the compression chamber 1112 formed by the stationary scroll 110 and the moving scroll 120 to compress the gas. In the scroll compressor 100, since the first heat exchange channel 101 provided in the stationary scroll 110 is connected to the second heat exchange channel 102 provided in the housing 130, a heat exchange medium can be provided through a heat exchange device, such as a heat exchange apparatus. The heat exchange medium can be supplied from... The first flow channel 101A and the second flow channel 102A flow into one and out the other, and flow through the first heat exchange channel 101 and the second heat exchange channel 102 to cool the stationary scroll plate 110 and the shell 130. This reduces the heat generated by the stationary scroll plate 110 during gas compression and the heat transferred to the shell 130 when the motor 150 is working, thereby improving the reliability and stability of the scroll compressor 100. Furthermore, the scroll compressor 100 of this application can achieve cooling of the stationary scroll plate 110 and the shell 130 using the same set of heat exchange equipment, which has low cost and low energy consumption.
[0113] Please see Figures 4 to 8 , Figure 4 yes Figure 1 A three-dimensional structural diagram of the stationary scroll plate in a scroll compressor. Figure 5 yes Figure 4 A three-dimensional schematic diagram of the internal structure of the stationary vortex disk. Figure 6 yes Figure 5 A top-view structural diagram. Figure 7 yes Figure 6 sectional view diagram, Figure 8 yes Figure 6 Another cross-sectional schematic diagram, in some embodiments, is also shown in the accompanying diagram. Figure 1 as well as Figures 4 to 8 The stationary volute 110 includes a first base plate 111 and a first volute tooth 112. The first volute tooth 112 is disposed on the side of the first base plate 111 facing the moving volute 120, and the first volute tooth 112 meshes with the moving volute 120. The first heat exchange channel 101 is disposed on the side of the first base plate 111 away from the moving volute 120.
[0114] For example, the moving scroll 120 includes a second base disk 121 and a second scroll tooth 122, and the first scroll tooth 112 of the stationary scroll 110 and the second scroll tooth 122 of the moving scroll 120 mesh with each other so that the stationary scroll 110 and the moving scroll 120 together define the compression cavity 1112.
[0115] Specifically, the stationary volute 110 is composed of a first base plate 111 and a first volute tooth 112, and the moving volute 120 is composed of a second base plate 121 and a second volute tooth 122. The first base plate 111 can be a groove structure that opens toward the moving volute 120, and the second base plate 121 can be a plate structure.
[0116] In this embodiment, the first heat exchange channel 101 is located on the side of the first base plate 111 facing away from the moving scroll plate 120. Since the side of the first base plate 111 facing away from the moving scroll plate 120 usually has a large end face area, the first heat exchange channel 101 can have a long heat exchange path, which allows the heat exchange medium in the first heat exchange channel 101 to have a better cooling effect on the stationary scroll plate 110. Furthermore, the fact that the first heat exchange channel 101 is located on the side of the first base plate 111 facing away from the moving scroll plate 120 does not affect the meshing of the first scroll tooth 112 and the second scroll tooth 122.
[0117] In some embodiments, the first heat exchange channel 101 includes a plurality of first heat exchange sub-channels 1010, which are connected in sequence. One first heat exchange sub-channel 1010 is connected to the first channel outlet 101A, and the other first heat exchange sub-channel 1010 is connected to the second heat exchange channel 102.
[0118] In this embodiment, the first heat exchange channel 101 includes a plurality of first heat exchange sub-channels 1010, which are connected in sequence and form a meandering flow path. For example, the meandering flow path can be S-shaped or Z-shaped. The heat exchange medium flowing in from the first channel opening 101A can flow through each of the first heat exchange sub-channels 1010 in sequence. Within the limited area of the first base plate 111, the heat exchange medium can have a longer flow path, and the cooling effect of the heat exchange medium on the stationary vortex plate 110 is better.
[0119] In some embodiments, one of the two outermost and innermost first heat exchange sub-channels 1010 may be connected to the first flow channel opening 101A, and the other may be connected to the second heat exchange channel 102. In this way, the heat exchange medium flowing out of the first flow channel opening 101A can flow in from one of the two outermost and innermost first heat exchange sub-channels 1010, flow through each of the middle first heat exchange sub-channels 1010 in sequence, and then flow out from the other of the two outermost and innermost first heat exchange sub-channels 1010, thereby realizing the tortuous flow of the heat exchange medium within the first heat exchange channel 101. Figures 5 to 7 The diagram shows the heat exchange medium flowing out of the first flow channel 101A into the innermost first heat exchange sub-channel 1010, then flowing through each of the middle first heat exchange sub-channels 1010 in sequence, and finally flowing out from the outermost first heat exchange sub-channel 1010.
[0120] In some embodiments, the plurality of first heat exchange sub-channels 1010 are arc-shaped and concentrically arranged to match the circular cavity structure of the compression chamber 1112, thereby achieving a compact layout of the plurality of first heat exchange sub-channels 1010 on the first base plate 111. In other embodiments, the shape and arrangement of the plurality of first heat exchange sub-channels 1010 are not limited thereto.
[0121] In some embodiments, a connecting channel 101B is further provided in the first base plate 111. The connecting channel 101B is located at the end of the first heat exchange channel 101 away from the first channel opening 101A. The first heat exchange channel 101 can be connected to the second heat exchange channel 102 through the connecting channel 101B.
[0122] The connecting channel 101B can extend along the axial direction of the stationary volute 110 to the side of the stationary volute 110 facing the housing 130, so as to connect the second heat exchange channel 102. And the connecting channel 101B can be located radially outside the compression chamber 1112 to avoid interfering with the operation of the compression chamber 1112.
[0123] In some embodiments, see again Figure 1 The housing 130 includes a first housing 131 and a second housing 132 connected to each other. The end of the first housing 131 facing away from the second housing 132 is connected to a stationary volute 110. The first housing 131 and the stationary volute 110 enclose a first receiving cavity 1301, and a moving volute 120 is disposed in the first receiving cavity 1301. The first housing 131 and the second housing 132 enclose a second receiving cavity 1302, and a motor 150 is disposed in the second receiving cavity 1302.
[0124] In this embodiment, the housing 130 is jointly formed by a first housing 131 and a second housing 132, which facilitates the installation of the motor 150 into the second housing 132. In other embodiments, it is also possible that the housing 130 adopts a one-piece structure.
[0125] Specifically, the first housing 131 can be a groove structure with its opening facing the moving scroll 120, and a first receiving cavity 1301 for accommodating the moving scroll 120 can be formed within this groove structure; the second housing 132 can be a groove structure with its opening facing the first housing 131, and a second receiving cavity 1302 for accommodating the motor 150 can be formed within this groove structure. The motor 150 can be installed into the second housing 132 firstly, and then the second housing 132 and the first housing 131 can be connected and fixed together with fasteners such as bolts to form an integral structure of housing 130. In this way, the motor 150 can be accommodated in the second receiving cavity 1302 formed by the first housing 131 and the second housing 132. At the same time, the first crankshaft bearing 161 can be installed on the first housing 131, and the crankshaft 160 can pass through the first crankshaft bearing 161 installed on the first housing 131 and be connected to the moving scroll 120.
[0126] In some embodiments, the second heat exchange channel 102 is provided only in the first housing 131. Thus, the heat exchange medium flowing through the second heat exchange channel 102 can cool the first housing 131 and its adjacent components.
[0127] In some embodiments, the second heat exchange channel 102 is provided only in the second housing 132. Thus, the heat exchange medium flowing through the second heat exchange channel 102 can cool the second housing 132 and its adjacent components.
[0128] In some embodiments, a second heat exchange channel 102 is simultaneously disposed in both the first housing 131 and the second housing 132. Thus, the heat exchange medium flowing through the second heat exchange channel 102 can simultaneously cool both the first housing 131 and the second housing 132, thereby further improving the cooling effect.
[0129] In some embodiments, a second flow port 102A is provided in the second housing 132. Thus, the heat exchange medium flowing out of the second flow port 102A can flow out of the second housing 132 and exit the second housing 132 through the outlet 100B.
[0130] In some embodiments, a second flow port 102A is provided in the first housing 131. Thus, the heat exchange medium flowing out of the second flow port 102A can flow out of the first housing 131 and exit the first housing 131 through the outlet 100B.
[0131] In some embodiments, the second heat exchange channel 102 is disposed in the second housing 132; the first housing 131 is provided with a heat exchange cavity 103, which is connected to the first heat exchange channel 101 and the second heat exchange channel 102 respectively.
[0132] In this embodiment, the heat exchange medium flowing through the second heat exchange channel 102 can exchange heat with the second shell 132, thereby achieving cooling of the second shell 132.
[0133] Furthermore, the first housing 131 is provided with a heat exchange cavity 103, which is used to connect the first heat exchange channel 101 and the second heat exchange channel 102. The heat exchange medium flowing out of the first heat exchange channel 101 can flow into the heat exchange cavity 103, and then flow out of the heat exchange cavity 103 and into the second heat exchange channel 102. The heat exchange medium flowing through the heat exchange cavity 103 can cool the first housing 131 and its adjacent components.
[0134] In some embodiments, see also Figure 1 as well as Figures 9 to 12 , Figure 9 yes Figure 1 A three-dimensional structural diagram of the first housing in a scroll compressor. Figure 10 yes Figure 9 A top view of the first shell structure. Figure 11 yes Figure 9 A three-dimensional structural diagram of the first shell from another perspective. Figure 12 yes Figure 9 A bottom view of the first housing structure is provided. The first housing 131 includes an end plate 1311, a surrounding plate 1312, and a baffle 1313. The two ends of the surrounding plate 1312 are respectively connected to the end plate 1311 and the stationary volute 110. The side of the end plate 1311 facing the stationary volute 110 has a first groove 1311A. The baffle 1313 is connected to the side of the end plate 1311 facing the first receiving cavity 1301 and covers the first groove 1311A. The first receiving cavity 1301 is formed between the baffle 1313 and the stationary volute 110. The baffle 1313 and the first groove 1311A enclose and form a heat exchange cavity 103. To more clearly illustrate the first receiving cavity 1301 and the first groove 1311A formed within the first housing 131, Figure 9 and Figure 10 Baffle 1313 is not shown.
[0135] In this embodiment, a first receiving cavity 1301 and a heat exchange cavity 103 are formed inside the first housing 131. The first receiving cavity 1301 and the heat exchange cavity 103 are physically isolated by a baffle 1313. The heat exchange medium flowing through the heat exchange cavity 103 can exchange heat with the first housing 131, thereby cooling the first housing 131. Since the heat exchange medium can provide a relatively low temperature environment for the heat exchange cavity 103, and the moving volute 120 housed in the first receiving cavity 1301 is adjacent to the heat exchange cavity 103, although the moving volute 120 is not in direct contact with the heat exchange medium in the heat exchange cavity 103, the heat of the moving volute 120 can still be transferred to the baffle 1313 through the air in the first receiving cavity 1301, and then to the heat exchange medium in the heat exchange cavity 103, thereby cooling the moving volute 120.
[0136] Meanwhile, the heat from the first crankshaft bearing 161 and the second crankshaft bearing 162 can also be transferred to the heat exchange medium in the heat exchange chamber 103, thereby achieving cooling of the first crankshaft bearing 161 and the second crankshaft bearing 162.
[0137] In order to improve the heat exchange effect between the heat exchange medium in the heat exchange cavity 103 and the moving scroll 120, heat dissipation teeth are provided on the side of the moving scroll 120 facing the end plate 1311 to increase the heat exchange area and thus improve the heat exchange effect.
[0138] In some embodiments, the end plate 1311 is provided with a crankshaft mounting hole 1303, the heat exchange cavity 103 is arranged in an arc shape and surrounds the crankshaft mounting hole 1303, and the two ends of the heat exchange cavity 103 along its extension direction are respectively connected to the first heat exchange channel 101 and the second heat exchange channel 102.
[0139] The crankshaft mounting hole 1303 is used for the crankshaft 160 to pass through and for accommodating and mounting the first crankshaft bearing 161. The heat exchange cavity 103 is arc-shaped and surrounds the crankshaft mounting hole 1303, which allows the heat exchange cavity 103 to avoid the crankshaft mounting hole 1303 and the first crankshaft bearing 161 inside it. Furthermore, the heat exchange cavity 103 occupies a large area on the end plate 1311, thereby improving the cooling effect on the moving scroll 120.
[0140] In some embodiments, the first housing 131 is further provided with an inlet hole 1031 and an outlet hole 1032. The heat exchange cavity 103 is connected to the communication channel 101B in the stationary vortex disk 110 through the inlet hole 1031, and the heat exchange cavity 103 is connected to the second heat exchange channel 102 through the outlet hole 1032. The inlet hole 1031 and the outlet hole 1032 may be respectively provided at both ends of the heat exchange cavity 103 along its extension direction. The inlet hole 1031 can extend axially along the first housing 131. One end of the inlet hole 1031 is located on the side of the first housing 131 facing the stationary vortex disk 110, and the other end of the inlet hole 1031 is located at the bottom of the heat exchange cavity 103 near the end plate 1311, so that the heat exchange medium enters the inlet hole 1031 from the connecting channel 101B and then flows into the heat exchange cavity 103. One end of the outlet hole 1032 is located on the side of the first housing 131 away from the stationary vortex disk 110, and the other end of the outlet hole 1032 is located at the bottom of the heat exchange cavity 103 near the end plate 1311, so that the heat exchange medium flows from the heat exchange cavity 103 into the second heat exchange channel 102 through the outlet hole 1032. Thus, the heat exchange medium flowing through the first heat exchange channel 101 flows out of the connecting channel 101B and enters the heat exchange chamber 103 through the inlet hole 1031 to cool the moving volute 120, and then flows into the second heat exchange channel 102 through the outlet hole 1032.
[0141] Please see Figures 13 to 16 , Figure 13 yes Figure 1 A three-dimensional structural diagram of the second housing in a scroll compressor. Figure 14 yes Figure 13 A top view of the second shell structure. Figure 15 yes Figure 13 A three-dimensional structural diagram of the second shell from another perspective. Figure 16 yes Figure 13 The bottom view of the second housing structure is shown in some embodiments. The second housing 132 is provided with at least one heat exchange hole 1021. The at least one heat exchange hole 1021 penetrates the second housing 132 along the axial direction of the second housing 132. The at least one heat exchange hole 1021 is arranged at intervals along the circumference of the second housing 132, and the at least one heat exchange hole 1021 is connected in sequence to form a second heat exchange channel 102.
[0142] The heat exchange hole 1021 serves as a channel through which the heat exchange medium flows. The heat exchange medium can enter one of the heat exchange holes 1021 and flow through the other heat exchange holes 1021 in sequence, and then flow through the second flow channel 102A to the outlet 100B for discharge.
[0143] The heat exchange hole 1021 extends through the second housing 132 along the axial direction of the second housing 132. For example, the heat exchange hole 1021 may be parallel to the axial direction of the second housing 132 or intersect the axial direction of the second housing 132. The heat exchange hole 1021 may extend along a straight line, a curve, or a broken line.
[0144] There is at least one heat exchange hole 1021. For example, there may be one, two, three, four, five or more heat exchange holes 1021. It is understood that the more heat exchange holes 1021 there are, the longer the flow path of the heat exchange medium, and therefore the better the heat exchange effect between the heat exchange medium and the second shell 132, and the better the cooling effect on the second shell 132. Figure 15 and Figure 16 The case where the number of heat exchange holes 1021 is six is shown.
[0145] When there is only one heat exchange hole 1021, the end of the heat exchange hole 1021 facing the first housing 131 is connected to the first heat exchange channel 101, and the end of the heat exchange hole 1021 away from the first housing 131 is connected to the second channel opening 102A.
[0146] When there are multiple heat exchange holes 1021, one of the heat exchange holes 1021 is connected to the first heat exchange channel 101 at the end facing the first housing 131, and the other heat exchange hole 1021 adjacent to it is connected to the second channel opening 102A at the end facing away from the first housing 131. The other heat exchange holes 1021 are connected in sequence.
[0147] In this embodiment, at least one heat exchange hole 1021 penetrating the second housing 132 is provided inside the second housing 132. The heat exchange hole 1021 is easier to process and form inside the second housing 132. For example, each heat exchange hole 1021 can be obtained by subtractive processing of the second housing 132, or each heat exchange hole 1021 inside the second housing 132 can be obtained simultaneously during the forming process of the second housing 132 by a process such as extrusion molding.
[0148] This embodiment illustrates one way in which the second heat exchange channel 102 is formed by sequentially connecting at least one heat exchange hole 1021 that penetrates the second housing 132 axially. In other embodiments, the second heat exchange channel 102 within the second housing 132 can also be other structures, such as a meandering connecting hole structure. For example, the second heat exchange channel 102 can also extend in a tortuous manner along the circumference of the second housing 132, with the aim of covering the circumferential surface of the second housing 132 as much as possible, so as to extend the flow path of the heat exchange medium within the second housing 132.
[0149] In some embodiments, at least one heat exchange hole 1021 includes a first heat exchange hole 1021A, a second heat exchange hole 1021B, and at least one third heat exchange hole 1021C. The at least one third heat exchange hole 1021C is disposed circumferentially between the first heat exchange hole 1021A and the second heat exchange hole 1021B. One end of the first heat exchange hole 1021A facing the first housing 131 is connected to the first heat exchange channel 101, and the other end of the first heat exchange hole 1021A is connected to an adjacent third heat exchange hole 1021C. One end of the second heat exchange hole 1021B facing away from the first housing 131 is connected to an adjacent third heat exchange hole 1021C, and the second heat exchange hole 1021B is also connected to the second channel opening 102A. At least one third heat exchange hole 1021C is disposed at intervals and connected sequentially along the circumferential direction of the second housing 132.
[0150] Wherein, the first heat exchange hole 1021A is a heat exchange hole 1021 used to connect the first heat exchange flow channel 101, the second heat exchange hole 1021B is a heat exchange hole 1021 used to connect the second flow channel opening 102A, and the third heat exchange hole 1021C refers to each heat exchange hole 1021 located in the circumferential direction of the second shell 132 between the first heat exchange hole 1021A and the second heat exchange hole 1021B.
[0151] The number of third heat exchange holes 1021C can be one or more. Figure 15 and Figure 16 The illustration shows a case where there are four third heat exchange holes 1021C located in the circumferential direction of the second housing 132 between the first heat exchange hole 1021A and the second heat exchange hole 1021B. In other embodiments, the number of third heat exchange holes 1021C located in the circumferential direction of the second housing 132 between the first heat exchange hole 1021A and the second heat exchange hole 1021B can also be one, two, three, five, etc.
[0152] Thus, the heat exchange medium flowing out of the first heat exchange channel 101 can flow through the first heat exchange hole 1021A, then flow through each of the third heat exchange holes 1021C in sequence, and finally flow through the second heat exchange hole 1021B and then flow out of the outlet 100B through the second channel opening 102A. When the heat exchange medium flows through the second shell 132, it can have a longer heat exchange path, resulting in a better cooling effect on the second shell 132.
[0153] The second flow channel 102A can be disposed between the end of the second housing 132 facing the first housing 131 and the end facing away from the first housing 131. That is, the second flow channel 102A can be disposed on the circumferential sidewall of the second housing 132, so that the second flow channel 102A can be conveniently connected to the outlet 100B without interfering with the connection between the first housing 131 and the second housing 132. In other embodiments, it is also possible that the second flow channel 102A is disposed on the end face of the second housing 132.
[0154] In some embodiments, see again Figure 1 as well as Figure 9 and Figure 10 The first housing 131 is provided with a first connecting hole, which is connected to the first heat exchange channel 101 and the first heat exchange hole 1021A respectively.
[0155] In this embodiment, the first heat exchange channel 101 in the static vortex disk 110 and the first heat exchange hole 1021 in the second housing 132 are connected by a first connecting hole in the first housing 131. The heat exchange medium flowing through the first heat exchange channel 101 can enter the first heat exchange hole 1021 through the first connecting hole.
[0156] The first connecting hole refers to an intermediate connecting channel located inside the first housing 131, connecting the first heat exchange channel 101 inside the stationary volute 110 and the first heat exchange hole 1021 inside the second housing 132. This first connecting hole can be the heat exchange chamber 103 used for cooling the moving volute 120, as mentioned above; or it can be a flow channel for the heat exchange medium without cooling the moving volute 120.
[0157] When the first connecting hole includes a heat exchange cavity 103 for cooling the moving scroll 120, the first connecting hole also includes the inlet hole 1031 and the outlet hole 1032 mentioned above. The inlet hole 1031, the heat exchange cavity 103, and the outlet hole 1032 are sequentially connected to form the first connecting hole. In this way, the heat exchange medium flowing through the first heat exchange channel 101 first enters the heat exchange cavity 103 through the inlet hole 1031 to cool the first crankshaft bearing 161 and the second crankshaft bearing 162 of the moving scroll 120, and then enters the first heat exchange hole 1021A through the outlet hole 1032 to cool the second housing 132.
[0158] When the first connecting hole serves only as a flow channel for the heat exchange medium, it can be located within the enclosure 1312 of the first housing 130. This allows the heat exchange medium within the first connecting hole to not cool the moving scroll 120, but merely serve as a flow channel for the heat exchange medium. In this way, the heat exchange medium flowing through the first heat exchange channel 101 directly enters the first heat exchange hole 1021A through the first connecting hole to cool the second housing 132.
[0159] In some embodiments, see again Figure 11 and Figure 12 The first housing 131 has a first connecting groove 131A at one end facing the second housing 132, and the second housing 132 has a second connecting groove 1041 at one end away from the first housing 131. One of the third heat exchange holes 1021C and its adjacent third heat exchange hole 1021C are respectively connected to the first connecting groove 131A, and one of the third heat exchange holes 1021C and its adjacent third heat exchange hole 1021C are respectively connected to the second connecting groove 1041.
[0160] The first connecting groove 131A serves as a connecting channel between two adjacent third heat exchange holes 1021C. The first connecting groove 131A can be a recessed structure formed on the side of the first housing 131 facing away from the second housing 132. Specifically, a protruding ring 1310 is provided on the side of the first housing 131 facing away from the second housing 132. The first connecting groove 131A is formed on the side of the protruding ring 1310 facing the second housing 132, and the protruding ring 1310 also serves as the part where the first housing 131 and the second housing 132 are connected.
[0161] In this embodiment, a first connecting groove 131A is provided at the end of the first housing 131 facing the second housing 132. One of the third heat exchange holes 1021Cs can be connected to its adjacent third heat exchange hole 1021C through the first connecting groove 131A. This allows for communication between one end of two adjacent third heat exchange holes 1021Cs, thus enabling a smooth deflection of the heat exchange medium flowing through the two adjacent third heat exchange holes 1021Cs. Simultaneously, a second connecting groove 1041 is provided at the end of the second housing 132 away from the first housing 131. One of the third heat exchange holes 1021Cs can be connected to its adjacent third heat exchange hole 1021C through the second connecting groove 1041. This allows for communication between the other end of two adjacent third heat exchange holes 1021Cs, thus enabling a smooth deflection of the heat exchange medium flowing through the two adjacent third heat exchange holes 1021Cs. Therefore, the heat exchange medium can have a meandering flow path when flowing through each of the third heat exchange holes 1021Cs.
[0162] Furthermore, in this embodiment, the connecting channel between two adjacent third heat exchange holes 1021C is set at one end of the first housing 131 facing the second housing 132, which can further extend the path of the third heat exchange hole 1021C within the second housing 132.
[0163] The number of first connecting grooves 131A is related to the number of third heat exchange holes 1021C. All the third heat exchange holes 1021C can be grouped in pairs, and each group of third heat exchange holes 1021C corresponds to one first connecting groove 131A.
[0164] Figures 11 to 14 The diagram shows a scenario where there are four third heat exchange holes 1021C and two first connecting slots 131A. It can be reasonably inferred that when there are six third heat exchange holes 1021C, there are three first connecting slots 131A; when there are eight third heat exchange holes 1021C, there are four first connecting slots 131A; and when there are ten third heat exchange holes 1021C, there are five first connecting slots 131A.
[0165] In some embodiments, see again Figure 15 and Figure 16 The second housing 132 is provided with a third connecting groove 1042 at one end away from the first housing 131. The third connecting groove 1042 is connected to the first heat exchange hole 1021A and one of the third heat exchange holes 1021C respectively.
[0166] In this embodiment, a third connecting groove 1042 is provided at the end of the second housing 132 away from the first housing 131. The first heat exchange hole 1021A and one of the third heat exchange holes 1021C can be connected through the third connecting groove 1042. The heat exchange medium flowing out of the first heat exchange hole 1021A can flow into the third heat exchange hole 1021C through the third connecting groove 1042, so as to realize the smooth diversion of the heat exchange medium when it flows through the first heat exchange hole 1021A and one of the third heat exchange holes 1021C.
[0167] In some embodiments, the second housing 132 is provided with a fourth connecting groove 1043 at one end away from the first housing 131. The fourth connecting groove 1043 is connected to the second flow channel 102A and one of the third heat exchange holes 1021C.
[0168] In this embodiment, a fourth connecting groove 1043 is provided at one end of the second housing 132 away from the first housing 131. The heat exchange medium flowing out from a third heat exchange hole 1021C adjacent to the second heat exchange hole 1021B can enter the fourth connecting groove 1043, then flow out from the fourth connecting groove 1043 and into the second heat exchange hole 1021B, and then flow out of the second flow channel 102A, thereby realizing the smooth turning of the heat exchange medium when it flows through the third heat exchange hole 1021C and the second flow channel 102A.
[0169] The number of fourth connecting grooves 1043 is related to the number of third heat exchange holes 1021C. Apart from one third heat exchange hole 1021C adjacent to the first heat exchange hole 1021A and one third heat exchange hole 1021C adjacent to the second heat exchange hole 1021B, the remaining third heat exchange holes 1021C are grouped in pairs, and each group of third heat exchange holes 1021C corresponds to one fourth connecting groove 1043.
[0170] Figure 15 and Figure 16 The illustration shows a case where there are four third heat exchange holes 1021C and one fourth connecting groove 1043. In other embodiments, it can be reasonably inferred that when there are six third heat exchange holes 1021C, there are two fourth connecting grooves 1043; when there are eight third heat exchange holes 1021C, there are three fourth connecting grooves 1043; and when there are ten third heat exchange holes 1021C, there are four fourth connecting grooves 1043.
[0171] In some embodiments, when the second housing 132 is provided with a second connecting groove 1041, a third connecting groove 1042, and a fourth connecting groove 1043 at the end opposite to the first housing 131, in order to achieve mutual isolation between the second connecting groove 1041, the third connecting groove 1042, and the fourth connecting groove 1043, a rib 1320 is also provided on the side of the second housing 132 opposite to the first housing 131. A rib 1320 is provided between the second connecting groove 1041 and the third connecting groove 1042, a rib 1320 is provided between the second connecting groove 1041 and the fourth connecting groove 1043, and a rib 1320 is provided between the third connecting groove 1042 and the fourth connecting groove 1043, thereby achieving mutual isolation between the second connecting groove 1041, the third connecting groove 1042, and the fourth connecting groove 1043.
[0172] In some embodiments, the second heat exchange channel 102 includes at least one connecting groove 104, and the at least one connecting groove 104 is respectively disposed at one end of the housing 130 away from the stationary vortex disk 110.
[0173] Continue reading Figure 1 The scroll compressor 100 also includes a control component 140, which is connected to the end of the housing 130 away from the stationary scroll 110 and is electrically connected to the motor 150.
[0174] The control component 140 is used to control the operation of the motor 150. Specifically, it can be used to control the speed of the motor 150, thereby controlling the speed of the eccentric rotation and translation of the moving scroll plate 120 relative to the stationary scroll plate 110.
[0175] In related technologies, the control component 140 is usually a component independent of the scroll compressor 100, which can cause the wiring between the control component 140 and the motor 150 to be too long. The wires connecting the control component 140 and the motor 150 will have a heat problem. The excessively long wires generate more heat, which in turn causes a large amount of power loss.
[0176] In this embodiment, the control component 140 is integrated into the scroll compressor 100, and the wiring path between the control component 140 and the motor 150 can be greatly shortened. Therefore, the problem of power loss caused by excessive heat generated by the wires due to excessive wiring can be reduced.
[0177] The heat exchange medium flowing through the connecting groove 104 at the end of the housing 130 away from the stationary vortex disk 110 can also exchange heat with the control component 140, thereby cooling the control component 140 and improving the reliability and stability of the operation of the control component 140.
[0178] The structure of the connecting groove 104 can be referred to as the second connecting groove 1041, the third connecting groove 1042 and the fourth connecting groove 1043 in the above embodiments.
[0179] Continue reading Figure 1 Please refer to the following: Figures 17 to 21 , Figure 17 yes Figure 1 A three-dimensional structural diagram of the control component 140 in a scroll compressor. Figure 18 yes Figure 17 A top view of the control component 140. Figure 19 yes Figure 17 A three-dimensional structural diagram of the control component 140 from another perspective. Figure 20 yes Figure 17 A bottom view of the control component 140. Figure 21 yes Figure 18 A cross-sectional schematic diagram of the control component 140. In some embodiments, the control component 140 includes a control box 141 and a circuit board 142. The circuit board 142 is disposed inside the control box 141. The control box 141 is connected to the housing 130. The circuit board 142 is electrically connected to the motor 150. The side of the control box 141 facing the housing 130 is provided with a second groove 1411, which communicates with at least one communicating groove 104.
[0180] The control component 140 includes a control box 141 and a circuit board 142. The control box 141 is the outer shell of the control component 140 and is fixedly connected to the side of the housing 130 facing away from the stationary volute 110. The circuit board 142 is the core control component of the control component 140. Multiple control modules are integrated on the circuit board 142. The circuit board 142 is housed in the control box 141, and the control box 141 can protect the circuit board 142.
[0181] The second groove 1411 provided on the surface of the control box 141 is used to connect with the connecting groove 104 provided on the housing 130. The heat exchange medium flowing through the second heat exchange channel 102 in the housing 130 can enter the second groove 1411 on the surface of the control box 141 through the connecting groove 104, thereby improving the cooling effect on the circuit board 142 of the control box 141.
[0182] Specifically, the circuit board 142 is provided with multiple control modules in the area corresponding to the second groove 1411. When the control modules are working, they will generate a lot of heat. By placing the control modules that generate heat on the surface of the control box 141 in the second groove 1411, more heat exchange medium will accumulate in the second groove 1411, thereby enabling more effective cooling of the control modules.
[0183] The portion of the circuit board 142 outside the area corresponding to the second groove 1411 is typically provided with fasteners such as bolts for fixing the circuit board 142. The circuit board 142 is fixed to the side of the control box 141 facing the housing 130 by bolts and other fasteners. The circuit board 142 is usually not completely against the side of the control box 141 facing the housing 130, but has a certain distance from the side of the control box 141 facing the housing 130 to avoid the part of the circuit board 142 used for wiring the motor 150 (for example, the side of the circuit board 142 facing the housing 130 is provided with terminals for wiring the motor 150). Therefore, in this embodiment, the second groove 1411 is provided on the surface of the control box 141. The second groove 1411 can avoid the part of the circuit board 142 used for wiring the motor 150, and at the same time can be against other parts of the circuit board 142 to cool the circuit board 142 as much as possible.
[0184] Continue reading Figure 1 as well as Figures 18 to 21 In some embodiments, the control component 140 further includes a first connector 143 and a second connector 144, which are electrically connected to the circuit board 142 respectively. The first connector 143 and the second connector 144 extend from inside the control box 141 to outside the control box 141 respectively. The first connector 143 can be used as a motor power connector to connect to the power supply to provide power to the motor 150 and drive the motor 150 to work, thereby improving the stability and reliability of the motor 150 during operation. The second connector 144 can be used as a signal connector for the circuit board 142 to connect to the power supply to transmit signals to the circuit board 142.
[0185] This application also provides an oxygen generating device, which includes a scroll compressor, the specific structure of which is described in the above embodiments. Typically, the oxygen generating device also includes a molecular sieve and a heat exchanger, the heat exchanger being connected between the scroll compressor and the molecular sieve.
[0186] In this system, a scroll compressor is used to generate high-pressure air, which is then passed into a molecular sieve to produce high-concentration oxygen. This type of oxygen generator can also be called a molecular sieve oxygen generator.
[0187] Because the high-pressure air produced by the scroll compressor is at a high temperature, the temperature of the high-pressure air entering the molecular sieve during operation is also high. This reduces the performance of the molecular sieve and consequently affects the oxygen production efficiency of the oxygen generator. The heat exchanger is used to exchange heat with the high-pressure air produced by the scroll compressor, thereby reducing the temperature of the high-pressure air entering the molecular sieve.
[0188] The heat exchange device may include, but is not limited to, heat exchange tubes. Two molecular sieves may be provided, and the air discharged from the heat exchange device may alternately enter the two molecular sieves.
[0189] The working principle of this oxygen generator is roughly as follows: outside air enters the scroll compressor, which compresses the air. As the pressure increases, the temperature also increases. The high-temperature air then enters the heat exchanger for heat exchange. The compressed air after heat exchange then enters the molecular sieve to produce oxygen. The produced oxygen can enter the storage tank and then be supplied to users through the oxygen outlet (the oxygen production process of the molecular sieve oxygen generator is existing technology and will not be described in detail).
[0190] Since this oxygen generating equipment adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
