The performance, vibration noise, reliability, sealing, etc. of electric compressors are all important factors affecting their operation.

[0003] At present, the static vortex wall of general compressors is closed, and the vortex air suction is not smooth, which leads to greater pressure loss, increased power consumption, and a decrease in the COP of the compressor. The COP of the compressor refers to the ratio of the cooling capacity of the compressor to the input power (the consumed electrical power W). The higher the COP value, the higher the efficiency of the compressor and the more energy-saving the air conditioner is. Summary of the invention

[0010] Optionally, the suction section occupies less than 80% of the circumference of the full circle.

[0011] Optionally, each of the outer retaining walls is provided with a first notch.

[0012] Optionally, a second notch is provided on a side of the stator disk where the stator vortex wall is not provided.

[0013] Optionally, a first ventilation groove is provided at the bottom of the first tooth top sealing groove, the width of the first ventilation groove is smaller than the width of the first tooth top sealing groove, and the first ventilation groove can be connected to the exhaust port.

It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0057] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0058] See also Figure 1The present invention provides an embodiment of a static scroll, comprising: a static disk 10, a static scroll wall 1 and a plurality of peripheral retaining walls, wherein the static disk 10 is a disc structure, and an exhaust port 11 is provided at the center of the static disk 10; the static scroll wall 1 is fixed to one end face of the static disk 10, the static scroll wall 1 and the static disk 10 are concentrically arranged, a first tooth top sealing groove 12 is provided at the top of the static scroll wall 1 along the vortex direction, and a first sealing strip 121 is provided in the first tooth top sealing groove 12; the height of the peripheral retaining wall is higher than the height of the static scroll wall 1, and the peripheral retaining wall is fixed to the end face of the static disk 10 and is located On the outside of the static vortex wall 1, the outer retaining wall includes a first sealing wall 101, a second sealing wall 102 and a supporting wall 103 arranged on the same circumference. The inner sides of the first sealing wall 101 and the second sealing wall 102 are fixed to the outer wall of the static vortex wall 1 and circumferentially block the static disc 10 into an air intake section a and a sealing section b. The supporting wall 103 is located on the air intake section a. There is a ventilation gap between the inner side of the supporting wall 103 and the outer side of the static vortex wall 1. The supporting wall 103 forms an air inlet 1011 with the first sealing wall 101 and the second sealing wall 102 respectively. When the static vortex and the movable vortex cooperate, a sealing ring is provided on the back of the movable vortex, and the sealing ring seals the sealing end b from the outside. Replacing the static disk baffle with a baffle structure with multiple intervals makes the air intake smoother, the cooling capacity increases, and the COP improves. The higher the COP value, the higher the efficiency of the compressor, and the more energy-saving the air conditioner is. That is, this structure can achieve the effect of saving electricity. At the same time, when the static scroll baffle is changed from continuous to interval, the weight of the static scroll is reduced. In addition, as the range of new energy vehicles is increasingly concerned, the requirements for lightweight vehicles are getting higher and higher, and the lightweighting of compressors and their internal components is imperative. By updating the closed static vortex wall to an open one, the weight of the scroll disk and compressor is reduced, and the range of new energy vehicles is increased.

[0059] Since the closed static vortex will have too many burrs during processing, updating the closed type to an open type can greatly improve the product process level and production efficiency, reduce production costs and improve product competitiveness.

[0060] In this example, see Figure 1 At least one third sealing wall 104 is provided on the sealing section b, and the inner side of the third sealing wall 104 is fixed to the static vortex wall 1 and blocks the sealing section b in the circumferential direction. The provision of the third sealing wall 104 can increase the overall strength of the static vortex retaining wall.

[0061] In this example, see Figure 1 The air intake section occupies less than 80% of the circumference of the whole circle, so as to ensure the air intake capacity.

[0062] In this example, see Figure 1, each of the outer retaining walls is provided with a first notch 105. Optionally, a second notch 106 is provided on the side of the static disk 10 where the static vortex wall 1 is not provided. The purpose of providing the first notch 105 and the second notch 106 is to facilitate the clamping of the static vortex by the fixture when the static vortex is processed. The notch can be positioned on the one hand, and on the other hand, the requirement for the clamping stroke of the fixture can be shortened.

[0063] In this embodiment, please refer to Figures 2 to 7 A compressor includes a fixed scroll and a movable scroll of any one of the above embodiments, the fixed scroll includes a fixed scroll wall 1, the movable scroll includes a movable scroll wall 2, the fixed scroll wall 1 is arranged on a fixed plate 10, and the movable scroll wall 2 is arranged on a movable plate, the fixed scroll wall 1 is provided with a first tooth top sealing groove 12 and a first sealing strip 121 arranged in the first tooth top sealing groove 12; the fixed scroll wall 1 and the movable scroll wall 2 have opposite rotation directions and can cooperate to form a plurality of compression chambers, specifically as follows Figure 2 As shown, when the movable scroll wall 2 and the static scroll wall 1 rotate relative to each other, compression chambers 1A, 1B, 2A and 2B are formed. Compression chambers 1A, 1B, 2A and 2B change dynamically during the rotation of the movable scroll wall 2. The compressed air in compression chambers 1A, 1B, 2A and 2B is discharged from the exhaust port 11 after being compressed. A second tooth top sealing groove 21 and a second sealing strip 211 placed in the second tooth top sealing groove 21 are provided on the movable scroll wall 2. A second ventilation groove 212 is provided at the bottom of the second tooth top sealing groove 21 along the rotation direction of the movable scroll wall 2. The second ventilation groove 212 is connected to the exhaust port 11 of the static scroll wall 1.

[0064] In this embodiment, the movable disk is provided with the movable scroll wall 2 on one side, and the medium-pressure chamber 20 is provided at the center of the other side of the movable disk. At least one back-pressure hole 2121 is provided at the bottom of the second ventilation groove 212, and the back-pressure hole 2121 is connected to the medium-pressure chamber 20. The back-pressure hole 2121 can be one of the illustrated ones, or two or more, and the traditional high-pressure is directly throttled to medium pressure and introduced into the medium-pressure chamber 20. The pressure is changed to be intermittently connected to the exhaust port of the static scroll wall 1 through the second ventilation groove 212 of the movable scroll wall 2, and the high pressure is throttled to medium pressure through the throttling of the second scroll tooth top sealing groove 21 and introduced into the medium-pressure chamber 20 through the back-pressure hole 2121 in the groove. When the back pressure is too large, the degree of fit between the dynamic and static vortices is high, which reduces the gap between the second sealing strip 211 and the second tooth top sealing groove 21 and the second ventilation groove 212, thereby increasing the throttling effect, reducing the intermediate pressure, moving the dynamic vortex wall 2 away from the static vortex wall 1, reducing the contact force between the dynamic and static vortices, reducing wear and power consumption, and improving the performance of the compressor; when the back pressure is too small, the degree of fit between the dynamic and static vortices is low, which increases the gap between the second sealing strip 211 and the second tooth top sealing groove 21 and the second ventilation groove 212, thereby reducing the throttling effect, increasing the intermediate pressure, moving the dynamic vortex wall 2 close to the static vortex wall 1, increasing the contact force between the dynamic and static vortices, reducing compression chamber leakage, and improving the performance of the compressor. The exhaust port 11 can be located at the center of the static vortex wall 1, and the high-pressure gas in the compression chamber 1A, compression chamber 1B, compression chamber 2A, and compression chamber 2B is passed from the exhaust port 11 into the second ventilation groove 212, so that the high-pressure gas can generate a push-out force on the second sealing strip 211, thereby making the sealing effect of the first sealing strip 121 and the second sealing strip 211 better. Optionally, in order to ensure the floating effect of the tooth top sealing strip and the performance of the compressor, the cross-sectional area S1 of the second ventilation groove and the area S2 of the exhaust port, S1<1 / 5S2. In order to further ensure its floating effect, optionally, within the period of one relative rotation of the moving vortex and the static vortex, the conduction time length of the second ventilation groove and the exhaust port is not more than 3 / 4 of a circle.

[0065] In this embodiment, please refer to Figures 2 to 7 A compressor includes a fixed scroll and a movable scroll of any one of the above embodiments, the fixed scroll includes a fixed scroll wall 1, and the movable scroll includes a movable scroll wall 2, the fixed scroll wall 1 is provided with a first tooth top sealing groove 12 and a first sealing strip 121 placed in the first tooth top sealing groove 12; a first ventilation groove 122 is provided at the bottom of the first tooth top sealing groove 12 along the rotation direction of the fixed scroll wall 1, and the first ventilation groove 122 is connected to the exhaust port 11 of the fixed scroll wall 1; the fixed scroll wall 1 and the movable scroll wall 2 have opposite rotation directions and can cooperate to form a plurality of compression chambers, specifically as follows Figure 2As shown, when the movable scroll wall 2 and the static scroll wall 1 rotate relative to each other, a plurality of compression chambers can be formed. During the rotation of the movable scroll wall 2, dynamic changes occur. The compressed air in each compression chamber is discharged from the exhaust port 11 after being compressed. A second tooth top sealing groove 21 is provided on the movable scroll wall 2. A second ventilation groove 212 and a second sealing strip 211 disposed in the second ventilation groove 212 are provided at the bottom of the second tooth top sealing groove 21 along the rotation direction of the movable scroll wall 2. The second ventilation groove 212 is connected to the exhaust port 11 of the static scroll wall 1.

[0066] In this embodiment, a medium-pressure chamber 20 is provided at the center of one side of the movable scroll wall 2 away from the static scroll wall 1, and at least one back-pressure hole 2121 is provided at the bottom of the second ventilation groove 212, and the back-pressure hole 2121 is connected to the medium-pressure chamber. The back-pressure hole 2121 can be one of the ones shown in the figure, or two or more, and the traditional high-pressure is directly throttled to medium pressure and introduced into the medium-pressure chamber 20. The pressure is changed to be intermittently connected to the exhaust port of the static scroll wall 1 through the second ventilation groove 212 of the movable scroll wall 2, and the high pressure is throttled to medium pressure through the throttling of the second scroll tooth top sealing groove 21 and introduced into the medium-pressure chamber 20 through the back-pressure hole 2121 in the groove. When the back pressure is too large, the dynamic and static vortexes fit well, so that the gap between the second sealing strip 211 and the second ventilation groove 212 is reduced, thereby increasing the throttling effect, reducing the medium pressure, and the dynamic vortex wall 2 moves away from the static vortex wall 1, and the dynamic and static vortex contact force is reduced, reducing wear and power consumption, and improving the performance of the compressor; when the back pressure is too small, the dynamic and static vortexes fit well, so that the gap between the second sealing strip 211 and the second ventilation groove 212 is increased, thereby reducing the throttling effect, increasing the medium pressure, and the dynamic vortex wall 2 moves close to the static vortex wall 1, and the dynamic and static vortex contact force is increased, reducing compression chamber leakage, and improving the performance of the compressor. The exhaust port 11 can be located at the center of the static vortex wall 1, and the high-pressure gas is passed from the exhaust port 11 into the first ventilation groove 122 and the second ventilation groove 212, so that the high-pressure gas can generate a push-out force on the first sealing strip 121 and the second sealing strip 211 respectively, so that the sealing effect of the first sealing strip 121 and the second sealing strip 211 is better. Optionally, in order to ensure the floating effect of the tooth top seal strip and the performance of the compressor, the total cross-sectional area of ​​the first ventilation groove S1, the total cross-sectional area of ​​the first ventilation groove S3, the area of ​​the exhaust port S2, S1<1 / 5S2, and S3<1 / 5S2. In order to further ensure its floating effect, optionally, within the period of one relative rotation of the movable scroll and the static scroll, the conduction time length of the first ventilation groove, the second ventilation groove and the exhaust port is no more than 3 / 4 of a circle.

[0067] In this embodiment, please refer to Figure 7, the groove width of the first ventilation groove 122 is smaller than the groove width of the first tooth top sealing groove 12, and the groove width of the second ventilation groove 212 is smaller than the groove width of the second tooth top sealing groove 21. Optionally, the first ventilation groove 122 is a square groove, and the first ventilation groove 122 and the first tooth top sealing groove 12 form a T-shaped structure, and the second ventilation groove 212 is a square groove, and the second ventilation groove 212 and the second tooth top sealing groove 21 form a T-shaped structure.

[0068] By setting the groove width of the first ventilation groove 122 to be smaller than the groove width of the first tooth top sealing groove 12, it is possible to avoid the first sealing strip from sinking, and at the same time it is possible to ensure that the high pressure gas can exert a force on the first sealing strip 121, thereby ensuring the floating sealing effect of the first sealing strip 121 and the second sealing strip 211. By setting the groove width of the second ventilation groove 212 to be smaller than the groove width of the second tooth top sealing groove 21, it is possible to avoid the second sealing strip from sinking, and at the same time it is possible to ensure that the high pressure gas can exert a force on the second sealing strip 211, thereby ensuring the floating sealing effect of the first sealing strip 121 and the second sealing strip 211.

[0069] In this embodiment, please refer to Figure 7 , the width of the first ventilation groove 122 is smaller than the width of the first tooth top sealing groove 12, and the width of the second ventilation groove 212 is smaller than the width of the second tooth top sealing groove 21.

By setting the width of the first ventilation groove 122 smaller than the width of the first tooth top sealing groove 12, it is possible to avoid the first sealing strip from sinking, and at the same time, it is possible to ensure that the high-pressure gas can exert a push-out force on the first sealing strip 121, thereby ensuring the floating sealing effect of the first sealing strip 121 and the second sealing strip 211.

[0070] In summary, the present invention changes the static disk baffle into a plurality of baffle structures arranged at intervals, so that the air intake is smoother, the cooling capacity is increased, and the COP is improved. The higher the COP value, the higher the efficiency of the compressor, and the more energy-saving the air conditioner is. That is, this structure can achieve the effect of saving electricity. At the same time, when the baffle of the static vortex is changed from continuous to interval, the weight of the static vortex is reduced. Moreover, as the cruising range of new energy vehicles is paid more and more attention, the requirements for lightweight vehicles are getting higher and higher, and the lightweighting of compressors and their internal components is imperative. By updating the closed static vortex wall to an open type, the weight of the vortex disk and the compressor is reduced, and the cruising range of new energy vehicles is improved.

[0071] Since the closed static vortex will have too many burrs during processing, by updating the closed type to an open type, the product process level and production efficiency can be greatly improved, the production cost can be reduced, and the competitiveness of the product can be improved. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
