Description

Technical Field

[0001] This application relates to the technical field of compressors, and particularly to an energy-saving integrated scroll electric compressor. Background Art

[0002] In the field of refrigeration technology, the compressor, as the power device of the refrigeration cycle system, is a driven fluid machine, and its main function is to lift low-pressure gas to high-pressure gas. Specifically, the compressor sucks in low-temperature and low-pressure refrigerant gas through the suction pipe, then compresses the gas using the internal mechanical structure, and finally discharges the high-temperature and high-pressure refrigerant gas through the discharge pipe, thereby providing power support for the entire refrigeration cycle.

[0003] Among many types of compressors, the electric scroll compressor is a positive-displacement compressor. Compared with other types of compressors, the electric scroll compressor has the characteristics of simple structure, small size, and light weight, which makes it competitive in many application scenarios. Its compression components mainly consist of a moving scroll disk and a stationary scroll disk, and the compression of gas is achieved through the relative movement between the two. For scroll compressors, volumetric efficiency and isentropic efficiency are the key factors affecting their overall efficiency. How to improve these two efficiency indicators has always been the focus and difficulty of research in this field.

[0004] During the actual operation of the electric scroll compressor, the heat dissipation problem has always been a difficult problem to be solved urgently. On the one hand, a large amount of heat is generated during the operation of the compressor motor. If this heat cannot be dissipated in a timely and effective manner, the motor temperature will continue to rise. Excessive temperature will accelerate the aging process of the insulating material, reduce its insulation performance, and thus affect the service life and operation reliability of the compressor. On the other hand, during the gas compression process, the gas temperature will rise. The high-temperature compressed gas will not only increase the power consumption of the compressor and reduce the compression efficiency. For example, high temperature may cause the sealing performance of the scroll disk to decline, thereby leading to an increase in leakage.

[0005] In addition, the common scroll electric compressors on the market usually place various components in a housing. Although this design simplifies the overall structure of the compressor to a certain extent, it brings some problems in the actual use process. For example, when maintenance or repair of the compressor is required, due to the tight integration of various components in a housing, the overall repair efficiency is low, and the disassembly and assembly process is cumbersome, which not only increases the maintenance cost and time, but may also cause secondary damage to the compressor due to improper operation. Therefore, although certain progress has been made in the field of refrigeration with electric scroll compressors, further improvements are still needed in terms of improving efficiency, solving the heat dissipation problem, and optimizing disassembly, assembly, maintenance, etc. Summary of the Invention

[0006] The purpose of the present application is to provide an energy-saving integrated scroll electric compressor, which can not only improve the heat dissipation efficiency and the operating efficiency of the compressor, but also has the advantages of convenient disassembly and assembly and easy maintenance. The purpose of the present application is achieved through the following technical solutions. The energy-saving integrated scroll electric compressor of the present application includes a base, a motor assembly, a fixed support assembly, a scroll disk assembly and a cover;

[0010] Wherein, the outer diameters of the motor housing, the support main body and the stationary disk housing are the same, and the base, the motor assembly, the fixed support assembly, the scroll disk assembly and the cover are stacked in sequence and sealed and fitted.

[0011] In one embodiment, the outer sides of the support main body, the stationary disk housing and the cover include first fixing holes, the base includes second fixing holes, the motor housing includes first fixing screw holes and second fixing screw holes.

[0017] In one embodiment, a medium inlet is formed on the motor housing, and a medium outlet is formed on the cover body.

[0018] In one embodiment, the moving disk base includes an accommodation cavity, an eccentric rotating block is arranged in the accommodation cavity, and an anti-self-rotation card slot is arranged between the accommodation cavity and the eccentric rotating block.

[0019] In one embodiment, the motor housing, the support main body, the static disk housing, and the cover body have the same thickness, and a reinforcing rib structure is arranged on the outer side.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] In the present application, the motor assembly, the fixed support assembly, the scroll disk assembly, etc. are respectively integrated on their own structures to form parts of the component housing. Each component forms an independent and cooperating module, realizing modular design. The motor housing directly serves as a part of the compressor housing. By utilizing the structure of the motor housing, the heat generated by the operation of the motor can be more directly dissipated into the surrounding environment, effectively solving the problem of poor heat dissipation of the motor in traditional scroll compressors. The fixed support assembly and the scroll disk assembly also directly serve as a part of the compressor housing, improving the heat dissipation performance of the compression components.

[0022] By providing first fixing holes on the support main body, the static disk housing, and the cover body, second fixing holes on the base, and first fixing screw holes and second fixing screw holes on the motor housing, and using first fastening screws and second fastening screws for sealed connection, rapid connection between components is achieved. While ensuring the overall sealing performance of the compressor, when maintenance or repair is required, only the corresponding fastening screws need to be removed to conveniently separate each component, greatly simplifying the disassembly and assembly process and reducing the maintenance cost and time.

[0023] Corresponding sealing mating surfaces are respectively arranged between the base and the motor housing, between the motor housing and the support main body, between the support main body and the static disk housing, and between the static disk housing and the cover body, and sealing rings (including anti-displacement holes and anti-displacement limit posts) are arranged in each mating surface, effectively preventing the leakage of refrigerant gas. The use of the sealing ring ensures the sealing performance between components, while the anti-displacement holes and anti-displacement limit posts further ensure the stability of the sealing ring during installation and use, avoiding leakage problems caused by the displacement of the sealing ring. <https: / / www.google.com / patents / US12345678>[^1] [^1]: This is a placeholder for a patent link, which should be left unchanged as per the instructions. If there is a real patent link, it should be inserted here. In this case, since it's just a placeholder, it remains as is.

[0024] The buffer gasket provided between the fixed support component and the moving disk base can eliminate the errors in the processing or assembly process, reduce the radial clearance and axial clearance between the moving scroll disk body and the static scroll disk body, thereby effectively reducing the possibility of gas leakage, improving the volumetric efficiency and isentropic efficiency of the compressor, reducing the power consumption, and enhancing the overall performance of the compressor. The weight ring accommodating cavity provided in the moving disk base and the weight ring placed in the accommodating cavity can perform dynamic balance adjustment according to the actual operation conditions of the moving scroll disk body, effectively balance the unbalanced force generated during the operation of the moving scroll disk body, reduce vibration and noise, and improve the operation stability and reliability of the compressor.

[0025] In summary, through structural optimization, the energy-saving integrated scroll electric compressor of the present application has achieved beneficial technical effects in aspects such as heat dissipation, disassembly and assembly maintenance, sealing, bearing support, dynamic balance, structural simplification, and layout optimization, effectively improving the performance, reliability, and maintainability of the compressor, and reducing the manufacturing cost and operation power consumption.

Detailed Embodiments

[0030] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only for explaining the present application and not for limiting the present application. Additionally, it should be noted that for the sake of description, only parts related to the present application rather than all structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0031] The terms "including" and "having" and any variations thereof in the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0032] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0033] With the increasing demands for energy conservation and emission reduction, equipment miniaturization, and convenient maintenance, traditional scroll electric compressors need to be improved in terms of structural design, heat dissipation efficiency, and maintenance convenience. Although traditional scroll electric compressors have advantages such as simple structure, small size, and light weight, in actual operation, if the heat generated by the motor during operation is difficult to dissipate efficiently, resulting in an increase in the motor temperature, it will not only affect the motor life but also may cause a series of failures due to high temperature. At the same time, the high temperature generated during the gas compression process will reduce the compression efficiency, increase power consumption, and affect the overall performance of the equipment. In addition, the components of the traditional compressor are integrated in a housing, and the disassembly and assembly maintenance process is cumbersome, which will increase the maintenance cost and time. The present application provides an energy-saving integrated scroll electric compressor with a new structure. Through structural design and layout optimization, the motor and scroll disk assembly are integrated, achieving efficient heat dissipation while simplifying the equipment structure and improving the maintenance convenience. Next, the specific structure and technical features of the energy-saving integrated scroll electric compressor of the present application will be introduced in detail. Please refer to Figures 1 to 3As shown in the figure, an energy-saving integrated scroll electric compressor in a preferred embodiment of the present application includes a base 100, a motor assembly 200, a fixed support assembly 300, a scroll disk assembly 400, and a cover body 500; the motor assembly 200 includes a motor housing 210, a motor stator 220, a motor rotor 230, and a rotating shaft 240. The motor stator 220 is fixedly arranged on the motor housing 210, and the rotating shaft 240 is fixed to the motor rotor 230. The fixed support assembly 300 includes a support main body and a bearing receiving hole arranged in the main body. The scroll disk assembly 400 includes a moving scroll disk body 420 and a stationary scroll disk body 410. The stationary scroll disk body 410 includes a stationary scroll strip and a stationary disk housing, and the moving scroll disk body 420 includes a moving scroll strip and a moving disk base. A scroll compression chamber is formed between the stationary scroll strip and the moving scroll strip. Among them, the outer diameters of the motor housing 210, the support main body, and the stationary disk housing are the same, and the base 100, the motor assembly 200, the fixed support assembly 300, the scroll disk assembly 400, and the cover body 500 are stacked in sequence and sealed and fitted together.

[0034] The motor assembly 200 is composed of a motor housing 210, a motor stator 220, a motor rotor 230, and a rotating shaft 240. As the power source of the compressor, the motor stator 220 is fixedly arranged on the motor housing 210 to provide a magnetic field for the rotation of the motor rotor 230. The rotating shaft 240 is fixed to the motor rotor 230. After being powered on, the motor rotor 230 drives the rotating shaft 240 to rotate at a high speed under the action of electromagnetic force. In particular, the lengths of the motor stator 220 and the motor rotor 230 are designed to be less than the length of the motor housing 210 and can be completely accommodated in the motor housing 210. The motor housing 210 can directly serve as a part of the compressor housing, and the overall structure is compact; the motor stator 220 is directly fixedly connected to the motor housing 210, providing a direct heat dissipation channel for the heat generated during the operation of the motor, effectively avoiding the accumulation of heat inside the motor stator 220 and reducing the risk of damage to the motor due to overheating.

[0035] The fixed support assembly 300 serves the functions of support and positioning. Specifically, it includes a support body and a bearing receiving hole provided within the body, providing a stable support framework for the internal structure of the compressor, and ensuring that each component maintains the correct position and relative relationship during operation. The bearing receiving hole is used to install the bearing, providing precise support and guidance for the rotation of the rotating shaft 240, and ensuring the smoothness and accuracy of the rotating shaft 240 during high-speed rotation. The scroll disk assembly 400 is the main compression component of the compressor, consisting of a moving scroll disk body 420 and a stationary scroll disk body 410. The stationary scroll disk body 410 includes a stationary scroll strip and a stationary disk housing. The stationary disk housing first serves as the carrier of the stationary scroll structure and secondly as one of the important components of the compressor housing, integrating the stationary scroll structure with the part forming the housing, simplifying the overall structure of the compressor. The moving scroll disk body 420 includes a moving scroll strip and a moving disk base. The moving scroll strip cooperates with the stationary scroll strip. Driven by the rotating shaft 240, the moving scroll disk body 420 makes a revolution and translational motion around the stationary scroll disk body 410, and a plurality of scroll compression chambers with continuously changing volumes are formed between the two. As the moving scroll disk body 420 moves, the medium is gradually inhaled, compressed, and discharged, realizing the compression process.

[0036] The outer diameters of the motor housing 210, the support body, and the stationary disk housing are the same, enabling better fitting and sealing when the components are stacked. The motor assembly 200, the fixed support assembly 300, the scroll disk assembly 400, and the cover body 500 are stacked in sequence and sealed and fitted together, capable of forming a closed compression space to prevent medium leakage.

[0037] In addition, from a technical perspective, forming the housing directly for each component and modularizing them into independent components enables independent processing and assembly of each component during the production and manufacturing process. During the maintenance and repair of the compressor, the modular components can be easily disassembled and replaced, reducing the maintenance difficulty and cost and improving the maintainability of the equipment.

[0038] In the structural design of the energy-saving integrated scroll electric compressor of the present application, the connection and sealing between each component are crucial. A plurality of first fixing holes are provided on the outer sides of the support body, the stationary disk housing, and the cover body 500. The distribution positions of these fixing holes can be calculated to ensure uniform force application during subsequent connection, avoiding component deformation or sealing failure caused by uneven force. Second fixing holes are also provided on the base 100, and their positions match the overall structural layout, providing a basis for the connection between the base 100 and the motor housing 210.

[0039] The motor housing 210 is provided with a first fixing screw hole and a second fixing screw hole correspondingly. The positions of the first fixing screw holes correspond one by one to the first fixing holes on the support body, the static plate housing and the cover body 500. When assembling, the first fastening screw 710 passes through the first fixing hole and is tightly connected to the first fixing screw hole, firmly and sealingly connecting the motor housing 210, the support body, the static plate housing and the cover body 500 together to form a tight integral structure. The second fastening screw 720 passes through the second fixing hole on the base 100 and is connected to the second fixing screw hole on the motor housing 210, realizing the sealed connection between the base 100 and the motor housing 210. Through this fastening connection method, the connection strength and sealing performance between the components of the compressor are ensured. It can withstand various forces and vibrations generated during the operation of the compressor, ensuring the relative positions of the components remain stable and unchanged. According to actual tests, there is no medium leakage under this connection and sealing method.

[0040] This modular connection method makes the assembly process of the compressor simpler and faster. Only need to connect the components together with fastening screws according to the predetermined order, which greatly shortens the assembly time and improves the production efficiency. During the maintenance process, if a certain component needs to be replaced, only need to remove the corresponding fastening screw, and the component can be easily separated, reducing the maintenance difficulty and cost. In addition, an outlet is provided at the center position of the static plate, and this outlet directly leads to the space formed by the static plate and the cover body 500, forming a circulation channel. The compressor outlet can be set on the cover body 500, and the size and shape of this outlet are designed according to the flow rate and pressure requirements of the compressor to ensure that the medium can be discharged from the compressor efficiently and stably and enter the subsequent circulation system. The optimized design of the compressor outlet on the cover body 500 ensures that the refrigerant gas can be discharged from the compressor efficiently and stably, and the efficient exhaust performance also helps to improve the volumetric efficiency of the compressor.

[0041] In the structure of the energy-saving integrated scroll electric compressor of the present application, the sealing and positioning between the components are crucial. In order to improve the sealing performance, in a further technical solution, a first sealing mating surface is designed between the base 100 and the motor housing 210, a second sealing mating surface is formed between the motor housing 210 and the support body, a third sealing mating surface exists between the support body and the static plate housing, and a fourth sealing mating surface is provided between the static plate housing and the cover body 500. The mating surfaces are processed with high precision and have extremely high surface flatness to ensure that the two can be tightly fitted.

[0042] To achieve an efficient sealing effect, corresponding sealing rings 600 are respectively arranged in each mating surface. The sealing rings 600 are made of rubber or elastic materials. The high-performance sealing rings 600 can closely fit the mating surface and fill in the tiny gaps. Even in high-pressure and high-temperature working environments, they can maintain a good sealing effect. At the same time, anti-displacement holes and anti-displacement limit posts can be further equipped. The anti-displacement holes cooperate with the corresponding convex structures to limit the movement range of the sealing ring 600 within the mating surface, preventing displacement caused by vibration or pressure changes. The anti-displacement limit posts further enhance the positioning stability of the sealing ring 600, ensuring that the sealing ring 600 is always in the correct sealing position, effectively avoiding leakage problems caused by the displacement of the sealing ring 600, and can also avoid misoperation during assembly. In a further improvement scheme, a sealing ring 600 accommodation groove is formed in the mating surface.

[0043] In addition, a limiting structure can be further arranged inside the compressor. The limiting structure can be a convex rib, a positioning pin or other forms of mechanical structures, which are arranged at specific positions of each component and cooperate with the corresponding structures on adjacent components. When the components are stacked in sequence, the limiting structure can accurately guide the installation position of the components, ensuring that each component is accurately in place according to the design requirements, and avoiding performance degradation or failures caused by installation deviations. During the assembly process of the compressor, even if there are certain errors by the operator, the limiting structure can play a guiding and corrective role, enabling the components to be accurately installed in the predetermined position. This helps to ensure the relative position accuracy between components, ensure the uniform gap between the moving scroll disk body 420 and the stationary scroll disk body 410, and improve the compression efficiency and performance of the compressor.

[0044] Furthermore, a partition is arranged on one side of the motor housing 210 close to the base 100. The partition includes a bearing fixing seat. The design of the bearing fixing seat can ensure the installation accuracy and stability requirements of the bearing. A positioning structure and installation holes are arranged inside. Through high-precision machining processes, the coaxiality and perpendicularity of the installation holes are guaranteed, enabling the bearing to be positioned at the predetermined position after installation, reducing vibration and noise problems caused by installation deviations. At the same time, the bearing fixing seat also has sufficient strength and stiffness to withstand various forces and torques generated during the operation of the bearing, ensuring that the bearing will not deviate during operation.

[0045] In the operation system of the compressor, the stable support of the rotating shaft 240 is one of the key factors to ensure the efficient and reliable operation of the compressor. In the technical solution of this application, the main bearing 250 and the auxiliary bearing 260 that are closely matched with the rotating shaft 240 are equipped. The auxiliary bearing 260 is arranged in the bearing fixing seat on the partition of the motor housing 210. The internal shape of the bearing fixing seat fits the outer shape of the auxiliary bearing 260, providing positioning and stable bearing for the auxiliary bearing 260. The main bearing 250 is installed in the bearing accommodating hole of the fixed support assembly 300. The size and shape of the bearing accommodating hole ensure that the main bearing 250 can be accurately installed therein and maintain good coaxiality with the rotating shaft 240. In order to further improve the installation accuracy and stability of the main bearing 250, a positioning step or a protruding structure may also be provided inside the bearing accommodating hole, which cooperates with the corresponding part of the main bearing 250 to prevent the main bearing 250 from having axial or radial displacement during operation. In addition, stiffeners or support structures may be designed around the bearing accommodating hole to enhance the overall strength of the fixed support assembly 300.

[0046] The reasonable setting of the main bearing 250 and the auxiliary bearing 260 provides support for the rotating shaft 240. The main bearing 250 mainly bears the main radial load of the rotating shaft 24, ensuring that the rotating shaft 240 does not have radial runout during high-speed rotation; the auxiliary bearing 260 plays an auxiliary support and positioning role, further improving the axial stability of the rotating shaft 240. The two work together, enabling the rotating shaft 240 to operate within a very small deviation range, greatly reducing the compressor vibration and noise problems caused by the instability of the rotating shaft 240.

[0047] In a further technical solution, a buffer gasket 310 is additionally provided between the fixed support assembly 300 and the moving disk base. It is made of a metal material or a polymer material with certain elasticity and corrosion resistance. The shape and size of the buffer gasket 310 match the contact surfaces of the fixed support assembly 300 and the moving disk base, and it can closely fit the two. Its surface is specially treated, and the moving disk base can slide relatively thereon with a very low friction coefficient. During the actual operation of the scroll compressor, there are inevitably certain radial and axial clearances in the compression chamber. Due to certain errors in the processing and assembly processes, an undesired clearance may be generated at the top of the compression chamber. The setting of the buffer gasket 310 can compensate for the errors in the processing or assembly process through its own elastic deformation, making the clearance between the moving scroll and the stationary scroll stable.

[0048] The buffer gasket 310 makes the axial clearance and radial clearance between the moving scroll and the stationary scroll more uniform and stable by compensating for machining and assembly errors, reducing the gas leakage in the compression chamber, and improving the volumetric efficiency of the compressor. Since the gas leakage is reduced, the energy consumed by the compressor during the compression process is correspondingly reduced. The absorption and dispersion of the axial gas force by the buffer gasket 310 reduce the load borne by the bearings, effectively reducing the power consumption of the scroll compressor. In addition, the elastic buffering effect of the buffer gasket 310 can effectively reduce the vibration and noise during the operation of the compressor.

[0049] In the design of the moving disk base structure in the technical solution of this application, more than 4 counterweight ring receiving cavities are provided (the specific number can be optimized according to the actual compressor model, specifications and balance requirements, such as 6, 8, etc.). The counterweight ring receiving cavities are evenly distributed inside the moving disk base, and their shapes and sizes are calculated to fit the counterweight rings of specific specifications. The counterweight ring receiving cavities can cooperate with the aforementioned gaskets to limit the counterweight rings in the receiving cavities, and the counterweight rings will not shake or shift after being placed. The positioning structure can be the protruding ribs or recessed card slots on the inner wall of the receiving cavity, which cooperate with the corresponding structures on the outer wall of the counterweight ring; the limiting device can be the elastic buckles or retaining pieces at the ends of the receiving cavity to fix the counterweight rings in place after they are put in.

[0050] The counterweight rings can be made of metal materials, such as tungsten alloy, lead alloy, etc., to ensure that the counterweight effect will not be affected by wear or corrosion during long-term use. The specifications of the counterweight rings can be designed diversely according to actual needs, such as different diameters, thicknesses and weights, so as to flexibly adjust the counterweight of the moving disk base. During the actual assembly process, the operator only needs to select the counterweight rings of appropriate specifications and quantities according to the balance test results of the moving disk base and put them into the corresponding counterweight ring receiving cavities to easily achieve counterweight adjustment. This assembly method greatly simplifies the configuration process of the counterweight block 440. Compared with the traditional method of welding or bolt-fixing the counterweight block 440 outside the moving disk base, it is more convenient and efficient and applicable to different specifications and scenarios. At the same time, since the counterweight ring receiving cavity is a groove-like structure formed inside the moving disk base, the bottom surface of the moving disk base can remain flat without obvious protruding structures, which is convenient for overall assembly. During the assembly process of the compressor, the flat bottom surface of the moving disk base can fit better with other components, reducing the assembly interference and clearance problems caused by the protruding structures, and improving the assembly accuracy and efficiency.

[0051] In the overall structural design of the compressor, the rational planning of the medium flow path is of vital importance. In the technical solution of the present application, the medium inlet is formed on the motor housing 210. Specifically, at a specific position of the motor housing 210, according to the requirements of the medium flow inside the compressor and the consideration of the overall layout, a medium inlet is opened through mechanical processing technology, such as drilling, milling, etc. The shape of the medium inlet is usually circular, and the diameter size is optimized according to factors such as the processing capacity of the compressor and the medium flow rate. At the same time, the medium outlet is formed on the cover body 500. At a suitable position of the cover body 500, a high-precision processing method is also used to form the medium outlet. The shape and size of the medium outlet match the scroll assembly 400, the exhaust channel and other structures inside the compressor to ensure that the medium can be smoothly discharged from the compressor after the compression process is completed. A special guide structure, such as a guide groove or a guide plate, may also be provided at the outlet to guide the medium to be discharged in a predetermined direction and speed, reduce turbulence during the discharge of the medium, and reduce energy loss.

[0052] The movable disc base structure of the present application is provided with an accommodating cavity, which is located at the center of the movable disc base and has a regular cylindrical shape or a special-shaped structure optimized according to specific design requirements. An eccentric rotating block 430 is provided in the accommodating cavity. The eccentric rotating block 430 is made of a high-strength, wear-resistant and high-strength metal material, such as alloy steel that has undergone special heat treatment. It has the shape of a cylindrical base 100 and a column formed on the cylinder for connection to the rotating shaft 240. The column is eccentrically designed on the bottom of the cylinder, and the eccentric distance is calculated and matched according to the operating requirements of the movable disc base. The surface of the eccentric rotating block 430 is hardened to improve its wear resistance and fatigue resistance, and can maintain a stable size and shape during long-term high-speed operation.

[0053] To prevent the eccentric rotating block 430 from rotating during operation, an anti-rotation slot is provided between the accommodating chamber and the eccentric rotating block 430. This slot is formed by the interaction of a protrusion on the inner wall of the accommodating chamber and a groove on the outer wall of the eccentric rotating block 430. The protrusions are elongated and evenly distributed at specific locations on the inner wall of the accommodating chamber to ensure a tight fit with the groove on the eccentric rotating block 430. The groove matches the protrusion, with a moderate depth and width, effectively preventing rotation within the accommodating chamber.

[0054] The above structural design of the present application enables the rotating shaft 240 not to adopt the traditional crankshaft structure. The rotating shaft 240 is in the form of a straight shaft and is limited by the main bearing 250 and the auxiliary bearing 260. The main bearing 250 is installed in the bearing receiving hole of the fixed support assembly 300, and the auxiliary bearing 260 is arranged in the bearing fixing seat on the partition plate of the motor housing 210. Both the main bearing 250 and the auxiliary bearing 260 adopt high-precision and low-friction rolling bearings, such as angular contact ball bearings or cylindrical roller bearings, which can bear the radial and axial loads of the rotating shaft 240 and ensure the stability and precision of the rotating shaft 240 during operation. The structure is simplified and the cost is reduced. Traditional scroll compressors usually use a crankshaft to achieve the eccentric movement of the moving disk. The crankshaft structure is complex, the processing difficulty is large, and the cost is relatively high. However, in the present application, by setting a receiving cavity and an eccentric rotating block 430 in the moving disk base and cooperating with the anti-rotation card slot, the eccentric movement of the moving disk is achieved without using a crankshaft, greatly simplifying the overall structure of the compressor. The straight-shaft form of the rotating shaft 240 can ensure the stability and precision of the rotating shaft 240 during operation, reducing the vibration and noise generated by self-rotation. Due to the structural simplification, the installation and maintenance of the compressor become more convenient. The installation of the straight-shaft form of the rotating shaft 240 is simpler, and the installation and disassembly of the main bearing 250 and the auxiliary bearing 260 are also easier.

[0055] In the overall architecture design of the present application, the motor housing 210, the support body, the stationary disk housing, and the cover body 500 adopt a unified and modular design concept. The thickness design comprehensively considers factors such as the force condition, material performance, and heat dissipation requirements of the compressor under different working conditions. Through simulation verification, it can be ensured that each component can reduce the weight as much as possible while meeting the strength requirements, improving the overall energy efficiency of the compressor. On the outer side of these components, a rib structure can be further set, in the form of a streamline or a grid, etc., to enhance the rigidity and anti-deformation ability of the components. The ribs and the component body are manufactured by an integral molding process, improving the strength of the components, dispersing stress to a certain extent, reducing fatigue damage caused by excessive local stress, and extending the service life of the compressor.

[0056] Furthermore, a heat dissipation channel structure can be constructed inside the housing. According to the generation and transfer laws of heat inside the compressor, by optimizing the channel orientation, cross-sectional shape, and size, the cooling medium (air or liquid) can flow smoothly in the channel, efficiently carrying away the heat generated during the operation of the compressor. To further improve the heat dissipation efficiency. In a preferred solution, a fan is integrated into the base 100, designed with low noise and high air volume. Through reasonable layout and speed control, a stable air flow can be generated to accelerate the air circulation in the heat dissipation channel, achieving air-cooled heat dissipation. Additionally, a liquid-cooling function can be integrated. Special cooling medium interfaces are provided on the housing, through which cooling liquids such as water or special coolants can be connected. When the cooling liquid flows in the heat dissipation channel, it can directly contact the high-temperature components inside the compressor and rapidly reduce the component temperature through heat exchange. The air-cooling and liquid-cooling heat dissipation methods can be flexibly switched or combined according to the actual working conditions to ensure that the compressor maintains good heat dissipation performance under different ambient temperatures and load conditions.

[0057] In addition, important structures such as support seats and fixing rings are also included in the compressor assembly. The support seats are made of high-strength and high-stability materials, and their shapes and sizes are designed according to the installation requirements of each component of the compressor, which can provide reliable support for the compressor and ensure its stability and accuracy during operation. The fixing ring is used to fix and connect each component to prevent the components from loosening or displacing during operation.

[0058] As can be seen from the foregoing, the overall structure of the energy-saving integrated scroll electric compressor of the present application is compact, which is formed by sequentially stacking and sealingly fitting a base, a motor assembly, a fixed support assembly, a scroll disk assembly, and a cover body. The motor assembly serves as the power source and is composed of a motor housing, a motor stator, a motor rotor, and a rotating shaft. The motor stator is fixed to the motor housing, and the rotating shaft is fixed to the motor rotor. After being energized, the motor rotor drives the rotating shaft to rotate at a high speed. The fixed support assembly includes a support body and a bearing receiving hole, which provides a stable support framework for the internal structure of the compressor, ensuring the correct positions and relative relationships of each component during operation. The bearing receiving hole is used to install bearings, providing precise support and guidance for the rotation of the rotating shaft to ensure its smoothness and accuracy.

[0059] The scroll disk assembly is the main compression component, which is composed of a moving scroll disk body and a stationary scroll disk body. The stationary scroll disk body includes a stationary scroll strip and a stationary disk housing. The stationary disk housing serves as the carrier of the stationary scroll structure and an important part of the compressor housing, simplifying the overall structure. The moving scroll disk body includes a moving scroll strip and a moving disk base. The moving and stationary scroll strips cooperate with each other. Driven by the rotating shaft, the moving scroll disk body makes a revolution and translation movement around the stationary scroll disk body, forming a plurality of scroll compression chambers with continuously changing volumes, realizing the suction, compression, and discharge of the medium.

[0060] In the design of the moving disk base, a buffer gasket is added to compensate for machining or assembly errors through elastic deformation, stabilize the gap between the moving scroll and the stationary scroll, reduce gas leakage, improve volumetric efficiency, and reduce power consumption and running vibration noise. At the same time, multiple counterweight ring accommodating cavities are provided on the moving disk base, which are evenly distributed and the shape and size are adapted to specific specifications of counterweight rings. The counterweight rings are limited in the accommodating cavities through a positioning structure and a limiting device. The specifications of the counterweight rings can be designed diversely, which is convenient for flexibly adjusting the counterweight of the moving disk base according to the balance test results, simplifies the configuration process of counterweight blocks, and improves the assembly accuracy and efficiency.

[0061] In summary, through the optimized design and coordinated operation of each component, the energy-saving integrated scroll electric compressor of the present application adopts a unified and modular design concept for the motor housing, the support body, the stationary disk housing, and the cover body, achieving efficient, stable, and reliable compression functions, and at the same time having the advantages of compact structure, convenient installation and maintenance, good sealing performance, and low vibration and noise.

[0062] The above is only a specific implementation manner of the present application, and any improvement made on the premise of the present application concept is regarded as the protection scope of the present application.
