Description

Technical Field

[0002] Currently, scroll compressors are widely used in residential and commercial refrigeration and air conditioning systems. With the rapid development of new energy electric vehicles, electric scroll compressors are increasingly used in vehicle thermal management. Due to the limitations of the vehicle's installation space, the size of electric scroll compressors for automotive air conditioning is usually limited. On the other hand, with the popularization of high-voltage fast charging, the heat dissipation requirements of vehicle batteries and electric drives are rapidly increasing, placing higher demands on the cooling capacity of electric scroll compressors. Therefore, maximizing the compressor's suction capacity within limited dimensions has become a key research direction for electric scroll compressors used in automotive air conditioning.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] Currently, scroll compressors are widely used in residential and commercial refrigeration and air conditioning systems. With the rapid development of new energy electric vehicles, electric scroll compressors are increasingly used in vehicle thermal management. Due to the limitations of the vehicle's installation space, the size of electric scroll compressors for automotive air conditioning is usually limited. On the other hand, with the popularization of high-voltage fast charging, the heat dissipation requirements of vehicle batteries and electric drives are rapidly increasing, placing higher demands on the cooling capacity of electric scroll compressors. Therefore, maximizing the compressor's suction capacity within limited dimensions has become a key research direction for electric scroll compressors used in automotive air conditioning.

[0040] To address the aforementioned technical issues, this application provides a scroll plate 100, which can be applied to scroll compressors. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the vortex disk 100 provided in the embodiments of this application.

[0041] like Figure 1 As shown, the scroll plate 100 provided in this embodiment includes a stationary scroll tooth 110 and a moving scroll tooth 120. The moving scroll tooth 120 is engaged with the stationary scroll tooth 110 and is rotatable relative to the stationary scroll tooth 110 to realize the air intake function of the scroll plate 100. The stationary vortex tooth 110 may include a first starting segment 111, a first involute segment, and a first arc segment. The first involute segment is connected to the first starting segment 111, and the first arc segment is connected to the first involute segment. The first starting segment 111, the first involute segment, and the first arc segment are arranged in a spiral shape to form the stationary vortex tooth 110. Simultaneously, the moving vortex tooth 120 may include a second starting segment 121, a second involute segment, and a second arc segment. The second involute segment is connected to the second starting segment 121, and the second arc segment is connected to the second involute segment. The second starting segment 121, the second involute segment, and the second arc segment are arranged in a spiral shape to form the moving vortex tooth 120. The first arc segment and the first involute segment are tangent at their connection point; and / or the second arc segment and the second involute segment are tangent at their connection point. It should be noted that the first involute segment and the second involute segment are both involutes 140 set at different positions (i.e., stationary volute 110 or moving volute 120).

[0042] It is understood that, in this embodiment, since the accommodating size of the scroll disk 100 is fixed, and the first involute segment is involute, the first arc segment and the second arc segment can be set, and the first arc segment and the first involute segment can be tangent at their connection point, and / or the second arc segment and the second involute segment can be tangent at their connection point, so that within the involute range of the first involute 140, the arc surface of the arc segment can be used to achieve air intake space (i.e., within the involute range of the first involute 140) through the arc surface of the arc segment. Figure 1The further expansion of the first intake space 151 and the second intake space 152 shown in the figure maximizes the intake volume of the compressor within the limited size of the scroll plate 100 to ensure the cooling effect of the electric vehicle.

[0043] In some embodiments, such as Figure 1 As shown, the second arc segment may include a first arc segment 131, a second arc segment 132, and a third arc segment 133 connected one by one. The first arc segment 131 is connected to the second involute segment. The first arc segment 131, the second arc segment 132, and the third arc segment 133 are all located on the inner and outer sides of the moving vortex tooth 120. The central angles corresponding to the first arc segment 131 located on the inner and outer sides of the moving vortex tooth 120 are the same, and / or the central angles corresponding to the second arc segment 132 located on the inner and outer sides of the moving vortex tooth 120 are the same, and / or the central angles corresponding to the third arc segment 133 located on the inner and outer sides of the moving vortex tooth 120 are the same. This not only expands the air intake space within the vortex disk 100 but also simplifies the preparation of the second arc segment.

[0044] It should be noted that, in this embodiment, the first arc segment 131, the second arc segment 132, and the third arc segment 133 can be tangent to each other and set continuously.

[0045] Please continue to refer to Figure 1 The first involute segment may include a first involute 140 segment and two sets of second involute 140 segments respectively disposed on the inner and outer sides of the stationary vortex tooth 110. The first arc segment includes two sets of first arc segments 131, two sets of second arc segments 132 and a third arc segment 133. The first set of first arc segments 131, the first set of second arc segments 132 and the third arc segment are connected one by one and are all located on the outer side of the stationary vortex tooth 110. The second set of first arc segments 131 and the second set of second arc segments 132 are connected one by one and are all located on the inner and outer sides of the stationary vortex tooth 110.

[0046] It should be noted that one end of one group of second involute segments 140 is connected to the first starting segment 111, and the other end is connected to the first group of first arc segments 131; at the same time, one end of the first involute segment 140 is connected to the first starting segment 111, and the other end is connected to the second group of first arc segments 131; one end of another group of second involute segments 140 is connected to the third arc segment 133, and the other end is connected to the second group of first arc segments 131.

[0047] In addition, in the above embodiments, the angles of the central angles corresponding to the inner and outer sides of the second group of first arc segments 131 on the inner and outer sides of the stationary vortex tooth 110 are the same, and / or the angles of the central angles corresponding to the inner and outer sides of the second group of second arc segments 132 on the inner and outer sides of the stationary vortex tooth 110 are the same, thereby expanding the air intake space inside the vortex disk 100 and making the preparation of the stationary vortex tooth 110 simpler.

[0048] Please see Figure 2 , Figure 2 for Figure 1 A schematic diagram showing the segmented breakdown of the moving scroll tooth 120 in the scroll disk 100. In some embodiments, such as... Figure 2 As shown, the moving vortex tooth 120 consists of the second starting segment 121 Second involute segment First arc segment 131 The second arc segment is 132. And the third arc segment 133 composition.

[0049] Second involute segment The center of the base circle is chosen to be the origin of the coordinate system, O0, with coordinates (x0=0, y0=0). Point A corresponds to the second involute segment. If the angle of expansion is φ0, then the second involute segment The mathematical expression is as follows:

[0050]

[0051]

[0052] In the formula:

[0053] Rg—Base circle radius;

[0054] —Shape line angle,

[0055] First arc segment 131 Let the center of the circle be O1, the coordinates be (x1, y1), and the corresponding central angle be φ1. Then the first arc is divided into segments 131. The mathematical expression is as follows:

[0056]

[0057]

[0058] In the formula:

[0059] R1 – First arc segment 131 radius;

[0060] —Shape line angle,

[0061] The second arc segment is 132. The center of the circle is O2, the coordinates are (x2, y2), and the corresponding central angle is φ2. Then the second arc is divided into 132 segments. The mathematical expression is as follows:

[0062]

[0063]

[0064] In the formula:

[0065] R2—Radius of the second arc segment 132;

[0066] —Expansion angle,

[0067] The third arc segment is 133. and the second involute segment The base circles are concentric, with the center coordinates (x0=0, y0=0) and the corresponding central angle is φ3. Therefore, the third arc is divided into segments of 133. The mathematical expression is as follows:

[0068]

[0069]

[0070] In the formula:

[0071] R3 - Third arc segment 133 radius;

[0072] —Shape line angle,

[0073] φ 总 —Total aspect ratio of the profile, φ 总 =φ0+φ1+φ2+φ3;

[0074] φ1, φ2, and φ3 should take values ​​under the following conditions:

[0075] 0 < φ1 ≤ π, 0 < φ2 ≤ π, 0 ≤ φ3 ≤ π;

[0076] 0 < φ1 + φ2 + φ3 ≤ 2π;

[0077] In the segmented expression of the above profile, the base circle radius Rg of the second involute segment, the radius R3 of the third arc segment 133 (i.e., the maximum outer diameter of the moving scroll tooth 120), the development angle φ0 of the second involute segment, the central angle φ1 corresponding to the first arc segment 131, the central angle φ2 corresponding to the second arc segment 132, and the central angle φ3 corresponding to the third arc segment 133 are the input parameters during profile design. The coordinates of the center O1 of the first arc segment 131, the coordinates of O2 of the second arc segment 132, the radius R1 of the first arc segment 131, and the radius R2 of the second arc segment 132 need to be solved based on the tangential continuity characteristics of the profile. The solution method is as follows—

[0078] Based on the base circle radius Rg and the development angle φ0 of the second involute segment, the coordinates (x, y) of point A can be determined. A ,y A )for:

[0079] x A =Rg*cosφ0+Rg*φ0*sinφ0;

[0080] y A =Rg*sinφ0-Rg*φ0*cosφ0;

[0081] Since point A is the second involute segment Segment 131 with the first arc From the point of tangency, we can know that line segment O1A is perpendicular to the second involute segment generator O0T at point A (tangent to the base circle at point T). The equation of line O1A can be expressed as:

[0082] y = y A +(xx A )*cot(φ0);

[0083] The first arc is divided into 131 segments. The coordinates (x1, y1) of the circle with center O1 satisfy:

[0084] y1=y A +(x1-x A )*cot(φ0); (1)

[0086] Since point B is the segment 131 of the first arc. Segment 132 with the second arc From the point of tangency, we can know that line segments O1B and O2B are collinear, and the coordinates (x1, y1) of point O1 and the coordinates (x2, y2) of point O2 have the following relationship:

[0087] (y2-y1) / (x2-x1)=cot(φ0+φ1); (2)

[0089] Similarly, point C is the starting point of segment 133 of the third arc, and its coordinates (x... C ,y C )for:

[0090] x C =R3*cos(φ0+φ1+φ2);

[0091] y C =R3*sin(φ0+φ1+φ2);

[0092] Since point C is the segment 132 of the second arc. Segment 133 with the third arc From the point of tangency, we can know that line segment O2C is collinear with line segment O0C, and the equation of line O2C can be expressed as:

[0093] y = y C +(xx C )*cot(φ0+φ1+φ2);

[0094] The second arc is divided into 132 segments. The circle with center O2 and coordinates (x2, y2) satisfies:

[0095] y2=y C +(x2-x C )*cot(φ0+φ1+φ2); (3)

[0097] Since line segments O1A and O1B have the same length, and line segments O2B and O2C have the same length, we can obtain the following formula:

[0098] |O1A|=|O1O2|+|O2B|=|O1O2|+|O2C|;

[0099] Right now:

[0100]

[0101] By solving equations (1) to (4) simultaneously, the coordinates (x1, y1) of point O1 and the coordinates (x2, y2) of point O2 can be obtained, and then the segment 131 of the first arc can be calculated. Segment 132 with the second arc Radius R1, R2:

[0102]

[0103]

[0104] Based on the above method, the profile of the inner side 122 of the moving vortex tooth can be obtained.

[0105] It is understandable that, since the hybrid profile of this scheme is a vortex profile with equal wall thickness, the 122 profile on the inner side of the moving vortex tooth can be offset outward by an equal distance from the wall thickness t of the vortex tooth to obtain the 123 profile on the outer side of the moving vortex tooth.

[0106] Furthermore, the starting segment of the 120 profile of the moving scroll tooth can be modified by PMP or by a combination of circular arc and straight line correction as needed to meet the milling cutter diameter requirements during scroll machining.

[0107] It should be noted that, based on the meshing characteristics of the moving and stationary scroll teeth 110, the eccentricity Ror of the outer 123 profile of the moving scroll tooth can be offset outward by an equal distance to obtain the 112 profile of the inner side of the stationary scroll tooth. Similarly, the eccentricity Ror of the inner 122 profile of the moving scroll tooth can be offset inward by an equal distance to obtain the 113 profile of the outer side of the stationary scroll tooth.

[0108] Please also see Figure 3 and Figure 4 , Figure 3 for Figure 1 The schematic diagram shown is of the intake volume inside the moving scroll tooth 122 of the scroll disk 100. Figure 4 for Figure 1 The diagram shows the intake volume of the inner side 112 of the stationary vortex tooth in the vortex disk 100.

[0109] In some embodiments, such as Figure 3 and Figure 4 As shown, the intake volume of the scroll disk 100 includes the intake volume V enclosed by the inner side 122 of the moving scroll teeth and the outer side 113 of the stationary scroll teeth. S1 The intake volume V enclosed by the outer side 123 of the moving vortex tooth and the inner side 112 of the stationary vortex tooth S2 ,in:

[0110] V S1 =S1*H=(S 动内 1+S 动内2 +S 动内3 +S 动内4 )*H;

[0111] B S1 =S2*H=(S 静内1 +S 静内2 +S 静内3 )*H;

[0112] In the formula:

[0113] S1—The air intake area formed by the inner side 122 of the moving vortex tooth and the outer side 113 of the stationary vortex tooth;

[0114] S2—The air intake area formed by the outer side 123 of the moving vortex tooth and the inner side 112 of the stationary vortex tooth;

[0115] S 动内1 —The air intake area enclosed by the involute 140 on the inner side 122 of the moving vortex tooth and the involute 140 on the outer side 113 of the stationary vortex tooth.

[0116] S 动内2 —The air intake area enclosed by the first arc segment 131 on the inner side 122 of the moving vortex tooth and the first arc segment 131 on the outer side 113 of the stationary vortex tooth;

[0117] S 动内3 —The air intake area enclosed by the second arc segment 132 on the inner side 122 of the moving vortex tooth and the second arc segment 132 on the outer side 113 of the stationary vortex tooth;

[0118] S 动内4 —The air intake area enclosed by the third arc segment 133 on the inner side 122 of the moving vortex tooth and the third arc segment 133 on the outer side 113 of the stationary vortex tooth;

[0119] S 静内1 —The air intake area enclosed by the outer side 123 involute 140 of the moving vortex tooth and the inner side 112 involute 140 of the stationary vortex tooth.

[0120] S 静内2 —The air intake area enclosed by the first arc segment 131 on the outer side 123 of the moving vortex tooth and the first arc segment 131 on the inner side 112 of the stationary vortex tooth;

[0121] S 静内2 —The air intake area enclosed by the second arc segment 132 on the outer side 123 of the moving vortex tooth and the second arc segment 132 on the inner side 112 of the stationary vortex tooth;

[0122] H – 110 tooth height for both moving and stationary spiral teeth;

[0123] Based on the obtained profile equation, the intake area of ​​each part is calculated to obtain the intake volume of the mixed profile.

[0124] Please see Figure 7 , Figure 7 A schematic diagram comparing the intake volume of the hybrid-shaped scroll disk 100 provided in this application embodiment and the involute-shaped scroll disk in the prior art. (See attached diagram.) Figure 7 As shown, by adjusting the central angle φ1 corresponding to the first arc segment 131, the central angle φ2 corresponding to the second arc segment 132, and the central angle φ3 corresponding to the third arc segment 133, different intake volumes can be obtained. While maintaining the base circle radius Rg and the total development angle φ... 总Under the premise that the tooth height H, eccentricity Ror, and maximum outer diameter of the 120mm moving scroll tooth are consistent, several typical angles of φ1, φ2, and φ3 were selected for intake volume calculation, and compared with the involute 140mm curve under the same conditions. The results are as follows: Figure 7 As shown in the figure. The calculation results show that the intake volume of the hybrid profile can be increased by 5.5% to 10.1% compared with the involute 140, and the intake volume is significantly increased. This allows the compressor's intake volume to be increased to the maximum extent within the limited size of the scroll plate 100, so as to ensure the cooling effect of the electric vehicle.

[0125] Unlike applications in home and commercial air conditioners, the electric scroll compressor 100 used in automotive air conditioners operates in a harsher environment, which places stricter requirements on the reliability of the compressor. Therefore, it is necessary to maximize the reliability of the compressor within a limited size.

[0126] Please see Figure 5 , Figure 5 This is a schematic diagram of the overall structure of the scroll disk 100 provided in another embodiment of this application. Figure 5 As shown, in another embodiment, the second arc segment may include a first arc segment 131, a second arc segment 132, and a third arc segment 133 connected one by one. The first arc segment 131, the second arc segment 132, and the third arc segment 133 are all disposed on the inner and outer sides of the moving volute 120, and the central angles corresponding to the inner and outer sides of the first arc segment 131 on the moving volute 120 are the same, and / or the central angles corresponding to the inner and outer sides of the second arc segment 132 on the moving volute 120 are the same, and / or the third arc segment 133... The central angles of the segments 133 on the inner and outer sides of the moving volute 120 are the same. The first arc segment 131 located on the inner side 122 of the moving volute is connected to the second starting segment 121, and the first arc segment 131 located on the outer side 123 of the moving volute is connected to the second involute segment. This allows for the improvement of the inner volute thickness of the moving volute 120 or the stationary volute 110 by setting arc segments that are thicker than the involute 140 in the inner ring of the moving volute 120 or the stationary volute 110, thereby improving the reliability of the volute disk 100.

[0127] Furthermore, such as Figure 5As shown, in the above embodiment, the first arc segment may include two sets of sequentially connected first arc segments 131, second arc segments 132, and third arc segments 133. One set of first arc segments 131, second arc segments 132, and third arc segments 133 is located inside the stationary volute tooth 110. The first arc segment 131 in one set is connected to the first involute segment, and in the same radial direction of the volute disk 100, the radius of the first arc segment 131 in one set is approximately the same as the radius of the third arc segment 133 located inside the moving volute tooth 122. Meanwhile, the other set of first arc segments 131, second arc segments 132, and third arc segments 133 is located outside the stationary volute tooth 110. The first arc segment 131 in the other set is connected to the first starting segment 111, and the third arc segment 133 in the other set is connected to the first involute segment.

[0128] It should be noted that in this embodiment, the first arc segment 131, the second arc segment 132, and the third arc segment 133 can be set internally and continuously. At the same time, the various data in this embodiment can refer to the calculation method mentioned above.

[0129] Please see Figure 6 , Figure 6 This is a schematic diagram of the overall structure of the vortex disk 100 provided in another embodiment of this application. In another embodiment, such as... Figure 6 As shown, there are at least two sets of first and second involute segments, and each of the first and second arc segments includes at least two sets of sequentially connected first arc segments 131, second arc segments 132, and third arc segments 133. Specifically, at least two sets of first arc segments 131, at least two sets of second arc segments 132, and at least two sets of third arc segments 133 in the first arc segment are staggered with at least two sets of first involute segments; and / or at least two sets of first arc segments 131, at least two sets of second arc segments 132, and at least two sets of third arc segments 133 in the second arc segment are staggered with at least two sets of second involute segments. This achieves a balance between high reliability and high air intake of the scroll plate 100.
