DETAILED DESCRIPTION

[0072] The scroll compressor is a core component of the thermal management system of electric vehicles. Its structure and performance affect the energy consumption, noise and vibration level of the vehicle. The improvement of people's living standards and the thermal management requirements of electric vehicles have put forward higher requirements for the performance, noise and vibration of compressors. Variable speed is a way to improve the performance of compressors in response to variable working conditions. Realizing variable capacity (variable displacement) regulation based on variable speed will further improve the variable working condition performance of the compressor and expand the scope of use of the compressor.

[0073] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0074] like Figures 1 to 4The compressor 100 according to the embodiment of the present application comprises: a housing 20 and a plurality of compression units, wherein the plurality of compression units are arranged in the housing 20, and the compressor is used to compress a fluid. The compressor 100 according to the embodiment of the present application has a plurality of compression units, which can meet various working conditions and increase the application range of the compressor 100.

[0075] The multiple compression units in the present application can be arranged in parallel, series or mixed connection, or can be arranged so that some of the multiple compression units are connected to power, while the other compression units are not connected to power (not running). Through these arrangement forms, the displacement, pressure ratio, etc. of the compressor 100 can be adjusted. In order to adjust the displacement or pressure ratio of the compressor 100, the multiple compression units in the present application can include but are not limited to the following implementations.

[0076] Implementation method 1: Figure 1 and Figure 2 The plurality of compression units include a first compression unit 10a and a second compression unit 10b, and the first compression unit 10a and the second compression unit 10b have a first state and a second state.

[0077] like Figure 1 In the first state, the first compression unit 10a and the second compression unit 10b are connected in parallel, and the fluid can enter the compressor 100 from the suction port of the compressor, and enter the first compression unit 10a through the suction port of the first compression unit 10a, and enter the second compression unit 10b through the suction port of the second compression unit 10b. After being driven and compressed by the first compression unit 10a and the second compression unit 10b, the fluid is sent to the exhaust port of the compressor through the exhaust port of the first compression unit 10a and the exhaust port of the second compression unit 10b. Through the first compression unit 10a and the second compression unit 10b connected in parallel, the displacement of the compressor 100 can be the sum of the displacement of the first compression unit 10a and the displacement of the second compression unit 10b, and the compressor 100 can have a large displacement.

[0078] like Figure 2 , in the second state, the first compression unit 10a and the second compression unit 10b are connected in series. The fluid can enter the compressor 100 from the suction port of the compressor, and enter the first compression unit 10a through the suction port of the first compression unit 10a, and after being driven and compressed by the first compression unit 10a, it is sent out through the exhaust port of the first compression unit 10a; then enter the second compression unit 10b through the suction port of the second compression unit 10b, and after being driven and compressed by the second compression unit 10b, it is sent to the exhaust port of the compressor through the exhaust port of the second compression unit 10b. By connecting the first compression unit 10a and the second compression unit 10b in series, the volume ratio of the compressor 100 is the product of the volume ratio of the first compression unit 10a and the volume ratio of the second compression unit 10b, so that a large pressure ratio can be achieved.

[0079] The compressor 100 further includes a first valve group, and the first valve group is configured to control the first compression unit 10a and the second compression unit 10b to switch between the first state and the second state.

[0080] Optionally, in a first state, the first valve group controls the exhaust port of the first compression unit 10a to be connected to the exhaust port of the compressor, the intake port of the second compression unit 10b to be connected to the intake port of the compressor, and the first compression unit 10a and the second compression unit 10b are connected in parallel; in a second state, the first valve group is configured to control the exhaust port of the first compression unit 10a to be connected to the intake port of the second compression unit 10b, and the first compression unit 10a and the second compression unit 10b are connected in series.

[0081] The first valve group includes a first switch valve 213, which is used to control the on-off between the exhaust port of the first compression unit 10a and the suction port of the second compression unit 10b. In the first state, the first switch valve 213 is closed; in the second state, the first switch valve 213 is opened to connect the first compression unit with the second compression unit.

[0082] The first valve group also includes a first suction valve 212, and the suction port of the second compression unit can be selectively connected to the suction port of the compressor through the first suction valve 212. In some examples, the first suction valve 212 is configured as a one-way suction structure. That is, the first suction valve 212 is configured to be used for one-way conduction of airflow from the suction port of the compressor to the suction port of the second compression unit 10b, and when the fluid at the suction port of the second compression unit 10b flows toward the suction port of the compressor, it will be blocked by the first suction valve 212, wherein the first suction valve 212 has a certain opening pressure.

[0083] The first valve group further includes a first exhaust valve 211, and the exhaust port of the first compression unit is selectively connected to the exhaust port of the compressor through the first exhaust valve 211. In some examples, the first exhaust valve 211 is configured as a one-way exhaust structure, that is, the first exhaust valve 211 is configured for one-way communication of the airflow from the exhaust port of the first compression unit 10a to the exhaust port of the compressor, and when the fluid at the exhaust port of the compressor flows toward the exhaust port of the first compression unit 10a, it will be blocked by the first exhaust valve 211, wherein the first exhaust valve 211 has a certain opening pressure.

[0084] The compressor 100 may further include a first exhaust chamber 2011, which is connected to the exhaust port of the first compression unit and can be selectively connected to the exhaust port of the compressor. The first exhaust chamber 2011 is connected to the exhaust port of the first compression unit 10a. After the fluid is compressed by the first compression unit 10a, it will flow to the first exhaust chamber 2011. In the first state, the first exhaust chamber 2011 is connected to the exhaust port of the compressor, and when the fluid pressure in the first exhaust chamber 2011 reaches a predetermined value, it will flow to the exhaust port of the compressor; in the second state, the first exhaust chamber 2011 is connected to the first suction chamber 2012.

[0085] The compressor 100 may further include a first suction chamber 2012, which is connected to the suction port of the second compression unit and may be selectively connected to the suction port of the compressor. The first suction chamber 2012 may be configured to be connected to the suction port of the second compression unit 10b, and the fluid in the first suction chamber 2012 may enter the second compression unit 10b. In the first state, the first suction chamber 2012 is connected to the suction port of the compressor, and when the fluid pressure in the first suction chamber 2012 is lower than a predetermined value, the fluid will flow from the suction port of the compressor into the first suction chamber 2012; in the second state, the first suction chamber 2012 is connected to the first exhaust chamber 2011.

[0086] The first exhaust chamber 2011 and the first suction chamber 2012 may be provided between the first compression unit 10a and the second compression unit 10b. Further, the first compression unit 10a and the second compression unit 10b are distributed along the axial direction of the housing 20, and a first partition 21 is provided between the first compression unit 10a and the second compression unit 10b, and the first partition 21 separates the first exhaust chamber 2011 and the first suction chamber 2012 along the axial direction of the housing 20. Through the first partition 21, the first exhaust chamber 2011 may be constructed in the space between the first partition 21 and the first compression unit 10a, and the first suction chamber 2012 may also be constructed between the first partition 21 and the second compression unit 10b, thereby simplifying the structure of the compressor 100.

[0087] Furthermore, in the first state and the second state, the first compression unit 10a and the second compression unit 10b are in transmission connection. In addition, the first compression unit 10a and the second compression unit 10b also have a third state, in which the first compression unit 10a and the second compression unit 10b are disconnected from transmission.

[0088] In combination with the foregoing, the compressor 100 may include but is not limited to the following operating modes.

[0089] Maximum displacement mode: Figure 1, the first compression unit 10a and the second compression unit 10b are connected in a transmission manner, and the first switch valve 213 (for example, a large displacement valve) can be controlled to be closed. At this time, the first compression unit 10a and the second compression unit 10b work in parallel, and the displacement of the system is the sum of the displacements of the first compression unit 10a and the second compression unit 10b. Figure 1 A part of the refrigerant enters the first compression unit from the side A of the first compression unit, is compressed by the first compression unit 10a, is directly exhausted to the first exhaust chamber 2011, is discharged to the exhaust channel 2005 through the first exhaust valve 211, is discharged from the exhaust port 2002 of the exhaust channel 2005, and is finally discharged from the exhaust port of the compressor; another part of the refrigerant enters the suction channel 2004 from the suction port 2001 of the suction channel 2004, is led to the first suction chamber 2012 through the first suction valve 212, is compressed by the second compression unit 10b, is exhausted to the third exhaust chamber 2030 on the outlet side of the second compression unit 10b, is discharged to the exhaust channel 2005, is discharged from the exhaust port 2002 of the exhaust channel 2005, and is finally discharged from the exhaust port of the compressor. Among them, the side A of the first compression unit and the suction port 2001 of the suction channel 2004 are both connected to the suction port of the compressor, and the exhaust port 2002 of the exhaust channel 2005 is connected to the exhaust port of the compressor.

[0090] Maximum pressure ratio mode: Figure 2 , the first compression unit 10a and the second compression unit 10b are connected in transmission, and the first switch valve 213 (such as a large displacement valve) can be controlled to open. At this time, the first compression unit 10a and the second compression unit 10b work in series, and the system's content volume ratio is the product of the content volume ratios of the two groups of compression units. Figure 2 The intermediate refrigerant enters the first compression unit from the side A of the first compression unit, is compressed by the first compression unit 10a, and is exhausted to the first exhaust chamber 2011, enters the first suction chamber 2012 through the first switch valve 213, and is compressed by the second compression unit 10b, and is exhausted to the third exhaust chamber 2030 on the outlet side of the second compression unit 10b, and then is exhausted to the exhaust channel 2005 through the one-way exhaust structure, and then is discharged from the exhaust port 2002 of the exhaust channel 2005, and finally is discharged from the exhaust port of the compressor. Among them, the side A of the first compression unit is connected to the suction port of the compressor, and the exhaust port 2002 of the exhaust channel 2005 is connected to the exhaust port of the compressor. During operation, if the refrigerant pressure in the first exhaust chamber 2011 is high, the excess refrigerant will be discharged into the exhaust channel 2005 through the first exhaust valve 211; if the refrigerant pressure in the first intake chamber 2012 is low, the refrigerant in the intake channel 2004 can enter the first intake chamber 2012 through the first intake valve 212 to replenish the gas.

[0091] Small displacement mode: The first compression unit 10a and the second compression unit 10b are disconnected, the first compression unit 10a can be connected to the power source, and the second compression unit 10b is separated from the power source. Among them, the first switch valve 213 (such as a large displacement valve) can be set to a closed state (it can also be an open state, but since the second compression unit 10b is not running, it will affect the fluid circulation). At this time, the first compression unit 10a works alone, the displacement of the system is the displacement of the first compression unit 10a, and the compression ratio is the compression ratio of the first compression unit 10a. Reference Figure 1 , the refrigerant enters the first compression unit from one side A of the first compression unit, is compressed by the first compression unit 10a, and is directly exhausted to the first exhaust chamber 2011, and then discharged to the exhaust channel 2005 through the first exhaust valve 211, and then discharged from the exhaust port 2002 of the exhaust channel 2005, and finally discharged from the exhaust port of the compressor. Among them, the side A of the first compression unit is connected to the suction port of the compressor, and the exhaust port 2002 of the exhaust channel 2005 is connected to the exhaust port of the compressor.

[0092] Implementation method 2: Figure 3 and Figure 4 The plurality of compression units include a first compression unit 10a, a second compression unit 10b and a third compression unit 10c. The working modes of the compressor 100 may be further increased to further increase the range of the working conditions of the compressor 100.

[0093] The first compression unit 10a and the second compression unit 10b have a first state and a second state. The first state and the second state can refer to the first embodiment and can be implemented by using the solution of the first embodiment.

[0094] The second compression unit 10b and the third compression unit 10c have a fourth state and a fifth state.

[0095] like Figure 3 In the fourth state, the second compression unit 10b and the third compression unit 10c are connected in parallel. The fluid can enter the compressor 100 from the suction port of the compressor, and enter the second compression unit 10b through the suction port of the second compression unit 10b, and enter the third compression unit 10c through the suction port of the third compression unit 10c. After being driven and compressed by the second compression unit 10b and the third compression unit 10c, the fluid is sent to the exhaust port of the compressor through the exhaust port of the second compression unit 10b and the exhaust port of the third compression unit 10c. By connecting the second compression unit 10b and the third compression unit 10c in parallel, the displacement of the compressor 100 can be no less than the sum of the displacements of the second compression unit 10b and the third compression unit 10c, and the compressor 100 can have a large displacement.

[0096] like Figure 4In the fifth state, the second compression unit 10b and the third compression unit 10c are connected in series. The fluid can enter the compressor 100 from the suction port of the compressor, and enter the second compression unit 10b through the suction port of the second compression unit 10b, and after being driven and compressed by the second compression unit 10b, it is sent out through the exhaust port of the second compression unit 10b; then enter the third compression unit 10c through the suction port of the third compression unit 10c, and after being driven and compressed by the third compression unit 10c, it is sent to the exhaust port of the compressor through the exhaust port of the third compression unit 10c. By connecting the second compression unit 10b and the third compression unit 10c in series, the volume ratio of the compressor 100 is not less than the product of the volume ratio of the second compression unit 10b and the volume ratio of the third compression unit 10c, so that a large pressure ratio can be achieved.

[0097] The first compression unit 10a, the second compression unit 10b and the third compression unit 10c in the present application can be connected in series, in parallel or in mixed connection.

The suction port of the third compression unit is selectively connected to the suction port of the compressor through the second suction valve 222. In some examples, the second suction valve 222 is configured as a one-way suction structure. That is, the second suction valve 222 is configured to be used for one-way conduction of airflow from the suction port of the compressor to the suction port of the third compression unit 10c, and when the fluid at the suction port of the third compression unit 10c flows toward the suction port of the compressor, it will be blocked by the second suction valve 222, wherein the second suction valve 222 has a certain opening pressure.

Through the second partition 22, the second exhaust chamber 2021 may be constructed in the space between the second partition 22 and the second compression unit 10b, and the second suction chamber 2022 may also be constructed between the second partition 22 and the third compression unit 10c, thereby simplifying the structure of the compressor 100.

[0106] In the fourth state and the fifth state, the second compression unit 10b and the third compression unit 10c are in transmission connection. In addition, the second compression unit 10b and the third compression unit 10c also have a sixth state, in which the first compression unit 10a and the second compression unit 10b are disconnected from each other.

At this time, the system displacement is the sum of the displacements of the first compression unit 10a, the second compression unit 10b and the third compression unit 10c, which is the maximum displacement. In this working mode, if Figure 3A part of the refrigerant enters the first compression unit from the side A of the first compression unit, is compressed by the first compression unit 10a, reaches the first exhaust chamber 2011, passes through the first exhaust valve 211 to the exhaust channel 2005, and then is discharged from the exhaust port 2002 of the exhaust channel 2005, and finally is discharged from the exhaust port of the compressor. At the same time, another part of the refrigerant enters the suction channel 2004 from the suction port 2001 of the suction channel 2004, enters the first suction chamber 2012 through the first suction valve 212, and then is compressed by the second compression unit 10b, reaches the second exhaust chamber 2021, passes through the second exhaust valve 221 to the exhaust channel 2005, and then is discharged from the exhaust port 2002 of the exhaust channel 2005, and finally is discharged from the exhaust port of the compressor. The last part of the refrigerant enters the air intake channel 2004 from the air intake port 2001 of the air intake channel 2004, enters the second air intake chamber 2022 through the second air intake valve 222, and then reaches the third air discharge chamber 2030 after being compressed by the third compression unit 10c, reaches the air discharge channel 2005 through the air outlet 2003, and then is discharged from the air discharge port 2002 of the air discharge channel 2005, and finally is discharged from the air discharge port of the compressor.

Among them, one side A of the first compression unit is connected to the suction port of the compressor, and the exhaust port 2002 of the exhaust channel 2005 is connected to the exhaust port of the compressor.

The first switch valve 213 is opened, and the second switch valve 223 is closed. At this time, the first compression unit 10a, the second compression unit 10b and the third compression unit 10c work in series. At this time, the maximum volume ratio of the system is the product of the volume ratios of the first compression unit 10a and the second compression unit 10b, and the displacement is the sum of the displacement of the first compression unit 10a and the displacement of the third compression unit 10c. In this working mode, a part of the refrigerant enters the first compression unit from one side A of the first compression unit, and after being compressed by the first compression unit 10a, reaches the first exhaust chamber 2011, and reaches the first suction chamber 2012 through the first switch valve 213, and then is compressed by the second compression unit 10b, reaches the second exhaust chamber 2021, and then enters the exhaust channel 2005 through the second exhaust valve 221, and is discharged from the exhaust port 2002 of the exhaust channel 2005, and finally is discharged from the exhaust port of the compressor; another part of the refrigerant enters the intake channel 2004 from the intake port 2001 of the intake channel 2004, enters the second intake chamber 2022 through the second intake valve, and then is compressed by the third compression unit 10c, reaches the third exhaust chamber 2030, reaches the exhaust channel 2005 through the outlet 2003, and is discharged from the exhaust port 2002 of the exhaust channel 2005, and finally is discharged from the exhaust port of the compressor. In the above process, if the pressure in the first exhaust chamber 2011 is too high, the refrigerant in the process can be discharged into the exhaust channel 2005 through the first exhaust valve 211; if the suction pressure in the first suction chamber 2012 is too low, the refrigerant in the suction channel 2004 will enter the first suction chamber 2012 through the first suction valve 212 for air replenishment.

[0113] Mode of medium pressure ratio and small displacement: the first compression unit 10a is connected to the second compression unit 10b in transmission, the second compression unit 10b is disconnected from the third compression unit 10c, the third compression unit 10c is not connected to power, the first switch valve 213 is opened, and the second switch valve 223 is closed.

[0114] It should be noted that in the present application, the first embodiment is mainly described by taking multiple compression units including the first compression unit 10a and the second compression unit 10b as an example; the second embodiment is mainly described by taking multiple compression units including the first compression unit 10a, the second compression unit 10b and the third compression unit 10c as an example. However, this does not mean that the number of compression units in the present application can only be two or three. The number of compression units in the present application can also be set to four, five or six, etc. According to the previous description of the present application, it is easy to obtain the arrangement form of a larger number of compression units and the series, parallel or mixed connection, etc., which will not be repeated in the present application.

[0115] like Figures 1 to 4 In some embodiments of the present application, multiple compression units are distributed along the axial direction in the housing 20. This can facilitate the arrangement of multiple compression units and facilitate the switching of multiple compression units between parallel, series, and mixed modes. Among them, an exhaust cavity and an air intake cavity can be set between adjacent compression units, and a switch valve that can connect and disconnect the exhaust cavity and the air intake cavity is set.

[0116] Among them, multiple compression units can be set as a transmission connection structure, and a controllable coupling or clutch is connected between adjacent compression units. Thereby, the transmission connection or separation between the multiple compression units is realized, so that power can be selectively provided to one or more compression units through the driving member. Of course, the compression units in this application can also be set as independent drives; or partially linked, partially independently driven, etc.

[0117] In combination with the above-mentioned embodiments, structures such as suction chambers and exhaust chambers are provided between the plurality of compression units, and air can be sucked from the suction port of the compressor through the suction chamber, and the exhaust chamber can exhaust air toward the exhaust port of the compressor. In order to facilitate the flow of fluid, the peripheral wall of the shell 20 of the present application is provided with an exhaust channel 2005 arranged along the axial direction of the shell 20, and the exhaust channel 2005 is connected to the exhaust port of the compressor. In addition, the peripheral wall of the shell 20 can also be provided with an suction channel 2004 arranged along the axial direction of the shell 20, and the suction channel 2004 is connected to the suction port of the compressor. Thereby, the flow path can be simplified and the stability of the operation of the compressor 100 can be improved.

[0118] Optionally, in the axial direction, the displacement of the compression unit at the previous stage is greater than the displacement of the compression unit at the next stage, so that the operating stability of the compressor 100 can be improved.

[0119] According to the compressor 100 of the embodiment of the present application, a controllable coupling and a large-diameter valve (such as the aforementioned first switch valve 213 or the second switch valve 223) can be used to connect multiple groups of compression units in series into a multi-stage compression structure, the first-stage compression unit has the largest displacement, and the displacement of the subsequent compression unit is smaller than that of the previous compression unit. The multi-stage compression unit can improve the content volume ratio of the compressor 100, thereby improving the compression ratio of the compressor 100 and enhancing the adaptability of the compressor 100 to large pressure ratio working conditions. In addition, using a controllable coupling and a large-diameter valve, multiple groups of compression units can be selectively connected in parallel, in series or in mixed connection, etc., to form compressors 100 with different displacements, thereby improving the performance of the compressor 100 in variable working conditions.

[0120] In the series mode, the exhaust position of each compression unit is designed with an independent back pressure chamber, and the back pressure chamber is connected to the air intake channel 2004 and the exhaust channel 2005 through a one-way valve. This avoids the situation of "holding air" and "lack of air" between the two-stage compression, and improves the adaptability of the multi-stage compression structure to variable working conditions. The back pressure chamber may include the aforementioned first air intake chamber 2012 and the first exhaust chamber 2011; or include the aforementioned second air intake chamber 2022 and the second exhaust chamber 2021.

[0121] In addition, by using controllable couplings and large-diameter valves, several groups of compression units can be selectively connected in series and connected in parallel with the remaining compression units to achieve the function of simultaneously changing the displacement and the internal volume ratio, further expanding the operating range of the compressor 100.

[0122] Combination Figures 5 to 7 The compression unit in the present application may be a vortex compression structure, wherein, for example Figure 6 In some embodiments, the compression unit 10 includes a fixed scroll 101, a movable scroll 102 and an anti-self-rotation structure (not shown in the figure), the anti-self-rotation structure is relatively stationary with the fixed scroll 101, one of the movable scroll 102 and the anti-self-rotation structure is provided with at least one anti-self-rotation ring 1021, and the other is provided with a positioning portion, which can be positioned at the anti-self-rotation ring in a translational manner around a fixed radius. Optionally, a plurality of anti-self-rotation rings are processed on the back of the bottom plate of the movable scroll, and the anti-self-rotation function can be realized by cooperating with a plurality of pins fixed at other positions.

[0123] In addition, if Figure 4 and Figure 5 The fixed scroll 101 is provided with an exhaust hole 1002 and an exhaust structure 1006, and the exhaust structure 1006 may include a reed valve plate 10061, a lift limiter 10062 and a fastener 10063. The reed valve plate can only be opened in one direction, and the lift is limited by the lift limiter. The above structure is a possible form of the exhaust structure.

[0124] The arrangement of multiple compression units in the present application includes but is not limited to the following embodiments.

[0125] In the first embodiment, at least one of the plurality of compression units is configured as a multi-tooth scroll compression structure.

[0126] In the second embodiment, at least one of the plurality of compression units is configured as a single-tooth scroll compression structure.

[0127] In the third embodiment, a part of the plurality of compression units is configured as a multi-tooth scroll compression structure, and another part is configured as a single-tooth scroll compression structure. For example, the last stage compression unit is configured as a single-tooth scroll compression structure, and the other compression units are configured as multi-tooth scroll compression structures.

[0128] The present application adopts a multi-tooth scroll structure, which utilizes the characteristics of multiple teeth. Compared with traditional positive displacement compressors, it has fewer moving parts, simpler assembly, less vibration and noise, smaller overall structural dimensions, and a smoother energy conversion process.

[0129] like Figures 8 to 10The multi-tooth scroll compression structure includes a first scroll plate 11 and a second scroll plate 12. The first scroll plate 11 includes a first bottom plate 111 and a plurality of first scroll teeth 112. The plurality of first scroll teeth 112 are arranged on the first bottom plate 111. The second scroll plate 12 includes a second bottom plate 121 and a plurality of second scroll teeth 122. The plurality of second scroll teeth 122 are arranged on the second bottom plate 121. The plurality of first scroll teeth 112 construct a plurality of compression channels 1001. The first bottom plate 111 or the second bottom plate 121 is provided with a plurality of exhaust holes 1002. The plurality of exhaust holes 1002 are respectively connected to the plurality of compression channels 1001. The plurality of second scroll teeth 122 are respectively meshed with the plurality of first scroll teeth 112, so as to drive the fluid to the corresponding exhaust holes 1002 along the corresponding compression channels 1001.

[0130] The plurality of first scroll teeth 112 and the plurality of second scroll teeth 122 are respectively meshed to form a scroll compression structure, and respectively drive the fluid of the corresponding compression channel 1001 to flow to the corresponding exhaust holes 1002. The processes of compressing the fluid in the plurality of compression channels 1001 are relatively independent, which can reduce the mutual influence of the fluid compression processes in the plurality of compression channels 1001, and can reduce the clearance volume of the compression unit 10, thereby improving the performance of the compression unit 10. In addition, compared with the solution of discharging the fluid of the plurality of compression channels 1001 through the same opening, the present application exhausts the fluid through the plurality of exhaust holes 1002, which can avoid or reduce the problems such as turbulence caused by the fluid converging at the same opening and affecting the compression performance.

[0131] In the present application, the number of first scroll teeth 112 may be two, three, four, six, etc., the number of second scroll teeth 122 may be the same as the number of first scroll teeth 112 , and the number of compression channels 1001 may be the same as the number of first scroll teeth 112 .

[0132] In addition, if Fig.11 , the inner end of the compression channel 1001 is closed, and the exhaust hole 1002 is connected to the inner end of the corresponding compression channel 1001. When the first scroll 11 and the second scroll 12 cooperate to compress the fluid, the fluid will be driven to flow to the inner end of the compression channel 1001. When the inner end of the compression channel 1001 is closed, the fluid will be discharged through the corresponding exhaust hole 1002. Multiple compression channels 1001 can be separated, and each compression channel 1001 is independently exhausted through the corresponding exhaust hole 1002, which can reduce the influence of multiple compression channels 1001 on each other. Multiple first volutes 112 can be distributed along the circumference of the first bottom plate 111, and compression channels 1001 will be formed between adjacent first volutes 112, and the inner ends of the compression channels 1001 constructed between adjacent first volutes 112 are closed.

[0133] In addition, if Fig.11The first scroll plate 11 also includes a protrusion 1003, which is arranged on the first bottom plate 111. A plurality of first scroll teeth 112 are connected to the protrusion 1003 and are arranged around the protrusion 1003 to form an integrated multi-tooth structure. The inner end of the compression channel 1001 constructed between adjacent first scroll teeth 112 can be closed by the protrusion 1003, and the connection of the protrusion 1003 can improve the structural strength of the plurality of first scroll teeth 112 and the first scroll teeth 112 and the first bottom plate 111.

[0134] Alternatively, if Fig.12 The plurality of second volutes 122 are distributed along the circumference of the second bottom plate 121, and the adjacent second volutes 122 are spaced apart to form a vertical multi-tooth structure, so that the plurality of second volutes 122 are respectively meshed with the plurality of first volutes 112 to compress the fluid.

[0135] like Fig.13 , the first scroll plate 11 is provided with a first central through hole 1004, and a plurality of first scroll teeth 112 are distributed around the first central through hole 1004; and / or, as Fig.14 , the second scroll plate 12 is provided with a second central through hole 1005, and a plurality of second scroll teeth 122 are distributed around the second central through hole 1005. When the compression unit 10 is connected to the crankshaft, the crankshaft can be passed through the first central through hole 1004 and the second central through hole 1005, so that when the crankshaft rotates, the first scroll plate 11 and the second scroll plate 12 are driven to perform relative translational motion. In this way, the crankshaft can be used to connect and pass through the compression unit 10, so that multiple compression units 10 can be connected by crankshaft transmission.

[0136] Of course, the first scroll 11 may not be provided with the first center through hole 1004, and the end of the crankshaft may be connected to the first scroll 11; or, the second scroll 12 may not be provided with the second center through hole 1005, and the end of the crankshaft may be connected to the second scroll 12.

[0137] In addition, combined Figures 15 to 18 , at least two of the plurality of first scroll teeth 112 mesh with the corresponding second scroll teeth 122 with a phase difference. With this arrangement, when at least two first scroll teeth 112 compress the fluid, the corresponding exhaust holes 1002 will not exhaust at the same time, so that the fluids in the plurality of compression channels 1001 will be discharged from the compression unit 10 in sequence, and the vibration caused by the plurality of exhaust holes 1002 exhausting gas at the same time or stopping exhausting gas at the same time can be avoided.

[0138] Furthermore, the meshing of multiple first vortex teeth 112 with corresponding second vortex teeth 122 has a phase difference, and the meshing phase difference α between the sequentially adjacent first vortex teeth 112 and corresponding second vortex teeth 122 satisfies, α=360° / i, where i is the number of first vortex teeth 112 .

[0139] For example, the number of first scroll teeth 112 is 2, and the meshing phase difference between the adjacent first scroll teeth 112 and the corresponding second scroll teeth 122 in timing is 180°. In other words, when the compression flow path corresponding to one first scroll tooth 112 is in the exhaust stage, the compression flow path corresponding to another first scroll tooth 112 is in the intake stage; for another example, the number of first scroll teeth 112 is 3, and the meshing phase difference between the adjacent first scroll teeth 112 and the corresponding second scroll teeth 122 in timing is 120°. In other words, when the compression flow path corresponding to one first scroll tooth 112 is in the intake stage, the compression flow path corresponding to another first scroll tooth 112 is in the compression stage, and the compression flow path corresponding to one first scroll tooth 112 is in the exhaust stage; for another example, the number of first scroll teeth 112 is 4, and the meshing phase difference between the adjacent first scroll teeth 112 and the corresponding second scroll teeth 122 in timing is 90°. Of course, in the present application, the number of the first scroll teeth 112 may also be 5, 6, etc., which will not be elaborated in this application.

[0140] In the present application, one of the first scroll 11 and the second scroll 12 may be a fixed scroll, and the other may be a movable scroll. The movable scroll may move around the axis of the fixed scroll at a fixed orbital radius, thereby achieving compression of the fluid. The cooperation of the first scroll 11 and the second scroll 12 in the present application includes but is not limited to the following embodiments.

[0141] In one embodiment, in combination Figures 10 to 14 The first scroll 11 is configured as a fixed scroll, and the second scroll 12 is configured as a movable scroll. The second scroll 12 moves around the axis of the first scroll 11 at a fixed orbital radius.

[0142] In another embodiment, if Fig.19 and Fig. 20 The first scroll 11 is configured as a movable scroll, and the second scroll 12 is configured as a stationary scroll. The first scroll 11 moves translationally around the axis of the second scroll 12 at a fixed orbital radius.

[0143] The meshing process of the first scroll 11 and the second scroll 12 can be referred to Figures 15 to 18 The compression unit 10 of the present application will significantly reduce the vibration and noise of the compressor.

[0144] In some embodiments, a plurality of exhaust holes 1002 are provided on the static scroll for exhausting the plurality of compression passages 1001. The compression unit 10 also includes a crankshaft, which includes a main journal and a connecting rod journal. The main journal is rotatably connected to the static scroll, and the connecting rod journal is rotatably connected to the movable scroll, which is used to drive the movable scroll to translate around the axis of the static scroll with a fixed radius. The static scroll is provided with a central through hole, and a plurality of exhaust holes 1002 are distributed around the central through hole. The central through hole can be used for the crankshaft to pass through, and the static scroll can be used to provide support for the crankshaft. At the same time, the exhaust holes 1002 are arranged around the central through hole to facilitate the exhaust of the compression unit 10 and avoid the crankshaft passing through the central through hole affecting the exhaust of the compression unit 10.

[0145] The multi-tooth vortex structure used in the above structure can significantly reduce the gas torque pulsation and exhaust mass flow pulsation, and can reduce the overall vibration and noise of the compressor. Fig.21 As shown, taking R134a refrigerant as an example, assuming that the compressor displacement is 34cc, the displacement of each compression channel 1001 is 8.5cc, the suction pressure is 0.3MPa, the exhaust pressure is 1.5MPa, the suction superheat is 10K, and the compressor speed is 3000rpm, then the gas torque pulsation value is 0.06N*m, and the traditional single-tooth scroll compressor is 1.26N*m, and the pulsation value is reduced by 95%. The obvious improvement of the gas torque pulsation value and the offset of the gas force will effectively improve the vibration and noise problems of the compressor.

[0146] In other embodiments of the present application, Fig. 22 As shown, taking R134a refrigerant as an example, assuming that the compressor displacement is 34cc, the displacement of each compression channel 1001 is 8.5cc, the suction pressure is 0.3MPa, the exhaust pressure is 1.5MPa, the suction superheat is 10K, and the compressor speed is 3000rpm, then the exhaust mass flow pulsation value is 0.010kg / s, while that of the traditional single-tooth scroll compressor is 0.056kg / s, and the pulsation value is reduced by 82%.

[0147] like Fig.23 and Fig.24 The single-tooth scroll compression structure includes a third scroll 13 and a fourth scroll 14, the third scroll 13 includes a third bottom plate 131 and a third scroll tooth 132 arranged on the third bottom plate 131, the fourth scroll 14 includes a fourth bottom plate 141 and a fourth scroll tooth 142 arranged on the fourth bottom plate 141, the fourth scroll tooth 142 is meshed with the third scroll tooth 141, wherein one of the third scroll 13 and the fourth scroll 14 is a movable scroll and the other is a fixed scroll.

[0148] As shown in the figure, a compressor 100 according to a specific embodiment of the present application includes a crankshaft 30 , and the crankshaft 30 transmits torque to a first compression unit 10 a , a second compression unit 10 b , and a third compression unit 10 c .

[0149] The first compression unit 10a and the second compression unit 10b include a first exhaust chamber 2011, a first exhaust valve 211, a first coupling 41, a first switch valve 213, a first suction chamber 2012, and a first suction valve 212; the second compression unit 10b and the third compression unit 10c include a second exhaust chamber 2021, a second exhaust valve 221, a second coupling 42, a second switch valve 223, a second suction chamber 2022, and a second suction valve 222. In addition, the back of the third compression unit 10c is followed by a third exhaust chamber 2030.

[0150] Among them, the inner core process of the movable scroll and the fixed scroll of the compression unit is shown in the figure, and the fixed scroll moves around the axis of the crankshaft 30 with a fixed orbital radius (counterclockwise on the paper). The multiple vortex teeth (for example, four) of the movable scroll form multiple meshing points with the vortex teeth of the fixed scroll respectively, and form multiple independent compression channels 1001. When the multiple vortex teeth structures are exactly the same, the displacement of each channel is one Nth of the total displacement of the scroll (N is the number of vortex teeth of the movable scroll). Multiple meshing points divide the volume between the movable scroll and the fixed scroll into multiple crescent-shaped cavities. As the translation continues, the meshing points move, and the volume of the crescent cavity gradually decreases, thereby doing work on the refrigerant. As the volume of the refrigerant is compressed, its position gradually moves from the edge of the scroll to the center of the scroll, close to multiple exhaust holes 1002.

[0151] In addition, the aforementioned controllable coupling can be electromagnetically controlled or pneumatically controlled. The first switch valve 213 or the second switch valve 223 can be electromagnetically controlled or pneumatically controlled.
