[0001] This application relates to the technical field of compressors, and more particularly to a compressor housing, compressor casing, compressor, and refrigeration system. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure refrigerant to high-pressure refrigerant, and it is an important power component of a refrigeration system.

[0008] The pressurization zone is used to install the compressor module, which is used to compress the refrigerant that enters the pressurization zone from the low-pressure zone.

[0009] In some embodiments, the flow channel is arranged axially around the compressor housing.

[0010] In some embodiments, the flow channel includes a first flow section and a second flow section that are connected.

[0011] The first flow section is arranged along the axial direction of the compressor housing, and one end of the first flow section is connected to the air inlet;

[0012] The second flow section is arranged axially around the compressor housing, one end of the second flow section is connected to the other end of the first flow section, and the other end of the second flow section is connected to the air outlet.

[0013] In some embodiments, the compressor housing includes:

[0014] A heat-conducting component having the aforementioned heat-conducting surface;

[0015] A cylindrical component is connected to the heat-conducting component and together with the heat-conducting component, forms the low-pressure zone and the pressurization zone; the cylindrical component has the air inlet.

[0016] The flow guide is located in the low-pressure area, connected to the heat-conducting component and the cylindrical component, and together with the heat-conducting component, forms the flow channel and the air outlet.

[0017] In some embodiments, the compressor housing further includes:

[0018] A support member, located within the low-pressure zone and connected to the heat-conducting member, has a shaft hole for accommodating the rotating shaft of the compression module, and the flow channel is arranged around the support member.

[0019] In some embodiments, a mounting groove is provided on the heat-conducting surface, and at least some of the electronic components of the controller are located in the mounting groove and are in thermal contact with the inner wall of the mounting groove.

[0020] Secondly, embodiments of this application provide a compressor housing, comprising:

[0021] The compressor housing described in the first aspect;

[0022] A compressor end cover is connected to the compressor housing and together with the compressor housing forms the high-pressure zone; along the axial direction of the compressor housing, the low-pressure zone, the boosting zone and the high-pressure zone are arranged sequentially, and the boosting zone is also connected to the high-pressure zone; the compressor end cover has an exhaust port that communicates with the high-pressure zone.

[0023] Thirdly, embodiments of this application provide a compressor, including:

[0024] Controller;

[0025] It also includes the compressor housing described in the first aspect or the compressor outer casing described in the second aspect, wherein the controller is mounted on the heat-conducting surface of the compressor housing and is in heat-conducting contact with the heat-conducting surface.

[0026] In some embodiments, the controller includes:

[0027] The outer casing is mounted on the heat-conducting surface and makes thermal contact with the heat-conducting surface.

[0028] Electronic components are mounted on the housing and are in thermal contact with the housing.

[0029] In some embodiments, a mounting groove is provided on the heat-conducting surface, and a clearance hole is provided in the area of ​​the housing opposite to the mounting groove. At least a portion of the electronic components of the controller are located in the mounting groove through the clearance hole and are in thermal contact with the inner wall of the mounting groove.

[0030] Fourthly, embodiments of this application provide a refrigeration system including the compressor described in the third aspect.

[0031] This application has at least the following beneficial effects:

[0032] The compressor housing has a low-pressure zone, a booster zone, a flow channel, an inlet, and an outlet. The flow channel connects the inlet and outlet, and the outlet connects to the low-pressure zone of the compressor housing, which in turn connects to the booster zone. With this design, external refrigerant enters through the inlet and flows in a concentrated manner under the constraint and guidance of the flow channel, forming a relatively accelerated flow state. It is then discharged into the low-pressure zone through the outlet. The refrigerant entering the low-pressure zone further enters the booster zone and is compressed by the compression module within the booster zone. Compared to related technologies where the refrigerant directly enters the low-pressure zone from the inlet and then diffuses naturally at a low velocity, the flow channel design makes the refrigerant flow path more concentrated, increasing the refrigerant velocity. Because the compressor housing has a heat-conducting surface in the area opposite to the flow channel, and this heat-conducting surface is used to make heat-conducting contact with the compressor controller, the refrigerant flowing at a relatively high speed in the flow channel helps to quickly remove the heat from the flow channel sidewall when it moves along the flow channel. This helps to quickly reduce the temperature of the heat-conducting surface opposite to the flow channel, which in turn helps the controller in heat-conducting contact with the heat-conducting surface to dissipate heat efficiently, thus improving the heat dissipation performance of the controller.

[0054] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0055] Most current automotive air conditioning compressors use refrigerant for heat dissipation, such as Figure 10As shown in the figure, this diagram illustrates the structural layout and internal refrigerant flow of an automotive air conditioning compressor in related technologies. Specifically, low-temperature, low-pressure gaseous refrigerant flows into the low-pressure zone of the compressor from the inlet. The controller drives the motor to rotate, and the motor drives the moving scroll plate to rotate via the crankshaft mechanism. The moving scroll plate and the stationary scroll plate work together to draw the refrigerant from the circumferential edge into the pressurization zone, and then gradually compress it to the central region, forming a high-temperature, high-pressure gaseous refrigerant that flows to the high-pressure zone and is finally discharged from the compressor. At the same time, the heat generated by the electronic components of the controller is transferred to the end of the compressor housing through the controller housing. The inner wall of the compressor housing end contacts the refrigerant for heat exchange, and some of the heat is absorbed and carried away by the refrigerant, thereby cooling the electronic components of the controller.

[0056] The applicant discovered that due to the large volume of the compressor's internal cavity, the refrigerant flows at a low velocity near the inner wall surface at the end of the compressor casing after entering the low-pressure zone. This results in poor heat exchange between the inner wall surface and the refrigerant, leading to poor heat dissipation performance of the controller and making the controller's electronic components prone to thermal runaway. Figure 11 As shown, this figure illustrates a thermal simulation cloud diagram of a compressor in related technologies, by... Figure 11 It can be seen that the highest junction temperature of the controller's power module chip is 178.04℃, which is severely over-temperature (the standard requirement is <157℃). For example... Figure 12 As shown, this figure is a temperature cross-section diagram of a compressor in related technologies. Figure 12 It can be seen that the temperature of the inner wall surface at the end of the compressor casing is 97.2℃, the temperature of the refrigerant is 37.9℃, and the convective temperature difference is 59.3℃. The heat exchange performance between the inner wall surface at the end of the compressor casing and the refrigerant is poor. The poor convective heat transfer here is the main reason for the large temperature difference between the inner wall surface and the refrigerant.

[0057] In view of this, the inventors designed a compressor housing, a compressor outer shell, a compressor and a refrigeration system. By adding a flow channel to the inner wall of the low-pressure zone of the compressor housing, the refrigerant enters the compressor housing and first passes through the flow channel, forming local forced convection heat transfer on the inner wall surface of the low-pressure zone, thereby improving the overall heat dissipation effect of the electronic components of the controller.

[0058] The compressor housing 110, compressor outer shell 100, compressor 1000 and refrigeration system provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0059] like Figures 1 to 9As shown, the compressor housing 110 has a low-pressure zone 110a and a boosting zone 110b that are connected. The compressor housing 110 also has an inlet 110c, an outlet 110d, and a flow channel 110e connecting the inlet 110c and the outlet 110d. The flow channel 110e is connected to the low-pressure zone 110a through the outlet 110d. A heat-conducting surface 110f is provided in the area of ​​the compressor housing 110 opposite to the flow channel 110e. The heat-conducting surface 110f is used for heat-conducting contact with the controller 200 of the compressor 1000. The boosting zone 110b is used to install the compression module 300, which is used to compress the refrigerant transferred from the low-pressure zone 110a to the boosting zone 110b.

[0060] The compressor 1000 can be of various types, including rotary vane compressors, scroll compressors, etc., and is not limited in this application. The compression module 300 is the working module of the compressor 1000. It is installed in the pressure boosting zone 110b and is used to mechanically compress the low-temperature, low-pressure refrigerant flowing from the low-pressure zone 110a into the pressure boosting zone 110b. Through internal structures (such as the meshing of the moving / stationary scroll plates in a scroll compressor, and the cooperation of the rotor and blades in a rotary vane compressor), the volume of the refrigerant is reduced, thereby increasing the pressure and temperature of the refrigerant and ultimately forming a high-temperature, high-pressure refrigerant. This provides a high-pressure gas source that meets the operating requirements for the subsequent circulation of refrigerant in the refrigeration system (such as flowing to the condenser to release heat).

[0061] The air inlet 110c is used to connect with the refrigerant from the outside. After the refrigerant enters through the air inlet 110c, it flows directionally along the flow channel 110e inside the compressor housing 110 and is finally discharged into the low-pressure zone 110a through the air outlet 110d for temporary storage. Subsequently, the refrigerant in the low-pressure zone 110a enters the pressurization zone 110b and completes the compression process under the action of the compression module 300.

[0062] like Figure 2 , Figure 3 and Figure 4 As shown, a heat-conducting surface 110f is provided in the area opposite to the flow channel 110e of the compressor housing 110. The heat-conducting surface 110f and the controller 200 transfer heat through heat-conducting contact. Specifically, it can be direct contact, or heat-conducting media such as heat-conducting adhesive or heat-conducting pads can be added between the two to enhance heat conduction. The specific form is not limited in this application.

[0063] The compressor housing 110 has a low-pressure zone 110a, a booster zone 110b, a flow channel 110e, an inlet 110c, and an outlet 110d. The flow channel 110e connects the inlet 110c and the outlet 110d. The outlet 110d connects to the low-pressure zone 110a of the compressor housing 110, and the low-pressure zone 110a connects to the booster zone 110b. With this design, external refrigerant enters through the inlet 110c and flows in a concentrated manner under the constraint and guidance of the flow channel 110e, forming a relatively accelerated flow state. It is then discharged into the low-pressure zone 110a through the outlet 110d. The refrigerant entering the low-pressure zone 110a further enters the booster zone 110b and is compressed by the compression module 300 within the booster zone 110b. Compared to the low-velocity state where the refrigerant directly enters the low-pressure zone 110a from the inlet 110c and diffuses naturally, the design of the flow channel 110e makes the refrigerant flow path more concentrated, thus increasing the refrigerant velocity. Since the compressor housing 110 has a heat-conducting surface 110f opposite to the flow channel 110e, and this surface 110f is used for heat-conducting contact with the controller 200 of the compressor 1000, the relatively high-speed refrigerant flowing within the flow channel 110e helps to quickly remove heat from the sidewalls of the flow channel 110e. This facilitates a rapid temperature reduction of the heat-conducting surface 110f opposite to the flow channel 110e, helping the controller 200, which is in heat-conducting contact with the surface 110f, to dissipate heat efficiently and improving the heat dissipation performance of the controller 200.

[0064] With this configuration, the heat generated by the electronic components 220 within the controller 200 can be quickly transferred to the refrigerant in the flow channel 110e via the heat-conducting surface 110f. The flowing refrigerant then rapidly carries the heat out of the compressor 1000, improving the heat dissipation effect of the controller 200 and effectively preventing thermal runaway of the electronic components 220. Figure 13 As shown, this figure illustrates the thermal simulation cloud diagram of the compressor in this application, by... Figure 13 It can be seen that the highest junction temperature of the controller's power module chip is 150.40℃, which is within the acceptable range (the standard requirement is <157℃). For example... Figure 14 As shown, this figure illustrates a temperature cross-section of the compressor in this application, by... Figure 14 It can be seen that the inner wall temperature of the flow channel 110e of the compressor housing 110 is 67.27℃, the refrigerant temperature is 39.54℃, and the convection temperature difference is 27.74℃. The heat exchange performance between the inner wall surface of the flow channel 110e of the compressor housing 110 and the refrigerant is good.

[0065] like Figure 5 and Figure 8 As shown, in some embodiments, the flow channel 110e is arranged around the axial direction X of the compressor housing 110.

[0066] The compressor housing 110 is cylindrical in shape, and the flow channel 110e is designed as an annular shape around the X-axis of the compressor housing 110. This design allows for a good fit with the shape of the compressor housing 110, making full use of the internal space of the compressor housing 110 and reducing space waste between the flow channel 110e and other structures of the compressor housing 110. It also makes the layout of the flow channel 110e more closely conform to the original shape of the compressor housing 110, eliminating the need for additional adjustments to the main structure of the compressor housing 110 to accommodate the flow channel 110e. Furthermore, the inner wall of the annular flow channel 110e is a continuous and smooth arc. When the refrigerant flows within the annular flow channel 110e, the airflow direction can naturally transition along the arc-shaped inner wall. Compared to the corners and edges that may exist in the non-annular flow channel 110e, this reduces local airflow disturbances caused by abrupt changes in the shape of the flow channel 110e during refrigerant flow, thereby reducing the resistance encountered by the refrigerant during flow and helping to maintain a stable flow state, ensuring the continuous operation of the heat exchange process.

[0067] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the flow channel 110e includes a first flow section 110e1 and a second flow section 110e2 that are connected; the first flow section 110e1 is arranged along the axial direction X of the compressor housing 110, and one end of the first flow section 110e1 is connected to the air inlet 110c; the second flow section 110e2 is arranged around the axial direction X of the first flow section 110e1, and one end of the second flow section 110e2 is connected to the other end of the first flow section 110e1, and the other end of the second flow section 110e2 is connected to the air outlet 110d.

[0068] The first flow section 110e1 is positioned along the axial direction X of the compressor housing 110, meaning that the length of the first flow section 110e1 extends along the axial direction X of the compressor housing 110. After the refrigerant enters through the inlet 110c, it first flows along the first flow section 110e1, then enters the second flow section 110e2, and finally exits through the outlet 110d into the low-pressure zone 110a. This two-section design of the flow channel 110e, under the influence of the second flow section 110e2, keeps the inlet 110c away from the heat-conducting surface 110f, and thus away from components such as the controller 200 located on the heat-conducting surface 110f. Since the inlet 110c typically needs to be connected to external pipes, this layout, with the inlet 110c away from the heat-conducting surface 110f, provides sufficient space for the connection between the pipes and the inlet 110c, reducing interference between the pipes and the housing 210 of the controller 200.

[0069] like Figure 6 and Figure 9As shown, in some embodiments, the compressor housing 110 includes a heat-conducting element 111, a cylindrical element 112, and a flow guide 113. The heat-conducting element 111 has a heat-conducting surface 110f. The cylindrical element 112 is connected to the heat-conducting element 111 and together with the heat-conducting element 111 forms a low-pressure zone 110a and a pressurization zone 110b. The cylindrical element 112 has an air inlet 110c. The flow guide 113 is located within the low-pressure zone 110a, connected to the heat-conducting element 111 and the cylindrical element 112, and together with the heat-conducting element 111 forms a flow channel 110e and an air outlet 110d.

[0070] The controller 200 can be mounted on the heat-conducting component 111 and make thermal contact with the heat-conducting surface 110f of the heat-conducting component 111. The cylindrical component 112 is fixedly connected to the heat-conducting component 111. After the cylindrical component 112 and the heat-conducting component 111 are fixedly connected, they together form a low-pressure zone 110a and a pressurization zone 110b. The compression module 300 is installed in the pressurization zone 110b formed by the cylindrical component 112. The flow guide 113 is located in the low-pressure zone 110a and is fixedly connected to both the heat-conducting component 111 and the cylindrical component 112. The heat-conducting component 111 and the flow guide 113 together form a flow channel 110e and an outlet 110d. During the high-speed flow of the refrigerant along the flow channel 110e, it exchanges heat with the heat-conducting component 111 and can quickly remove the heat on the heat-conducting component 111, thereby causing the temperature of the heat-conducting surface 110f of the heat-conducting component 111 to drop rapidly, thus cooling the controller 200. It is understandable that the heat-conducting component 111 needs to be made of a material with certain thermal conductivity, such as aluminum, copper and other metals, so that the heat generated by the controller 200 can be transferred to the heat-conducting component 111 through the heat-conducting surface 110f, and then transferred to the inner wall of the flow channel 110e formed by the heat-conducting component 111 and the flow guide 113, and finally absorbed by the refrigerant flowing in the flow channel 110e, and enter the low-pressure zone 110a with the refrigerant through the outlet 110d.

[0071] The heat-conducting component 111 and the cylindrical component 112 can be fixedly connected by welding, snap-fit, or other methods, or they can be integrally formed by casting, machining, or other methods (i.e., they are a single structure without additional connection), and this application does not impose any limitations on this. Similarly, the flow-guiding component 113 and the heat-conducting component 111 can be fixedly connected by welding, snap-fit, or other methods, or they can be integrally formed by casting, machining, or other methods, and this application does not impose any limitations on this. The cylindrical component 112 can be a tubular structure such as a round tube or a square tube, and this application does not impose any limitations on this.

[0072] In some embodiments, the flow channel 110e includes a first flow section 110e1 and a second flow section 110e2, the cylindrical member 112 has the first flow section 110e1, and the heat-conducting member 111 and the flow guide member 113 together form the second flow section 110e2.

[0073] like Figure 8 and Figure 9As shown, in some embodiments, the compressor housing 110 further includes a support 114 located within the low-pressure zone 110a and connected to the heat-conducting member 111. The support 114 has a shaft hole 114a for connection with the rotating shaft 310 of the compression module 300.

[0074] In these embodiments, the compressor 1000 can be a scroll compressor or a rotary vane compressor, etc., and the compression module 300 of these compressors 1000 has a rotating shaft 310. The shaft hole 114a of the support member 114 is used to support the rotating shaft 310 and limit the position of the rotating shaft 310. A bearing can be installed in the shaft hole 114a, and the rotating shaft 310 is rotatably mounted in the bearing. The support member 114 facilitates the installation of components such as the compression module 300.

[0075] In some embodiments, the flow channel 110e is disposed around the support 114.

[0076] The support member 114 is located within the low-pressure zone 110a and needs to provide support for the shaft 310 of the compression module 300. There is a certain amount of unused space around it. The flow channel 110e is set around the support member 114, so that the flow guide 113 can directly utilize this space. There is no need to open up an additional independent area in the low-pressure zone 110a for arranging the flow guide 113. This can reduce the space occupied by the flow guide 113 in the overall space of the low-pressure zone 110a, avoid the forced expansion of the volume of the low-pressure zone 110a due to the addition of the flow guide 113, and ensure that the temporary storage capacity of the refrigerant in the low-pressure zone 110a is not affected.

[0077] like Figure 6 As shown, in some embodiments, a mounting groove 110g is provided on the thermally conductive surface 110f, and at least some of the electronic components 220 of the controller 200 are located in the mounting groove 110g and are in thermally conductive contact with the inner wall of the mounting groove 110g.

[0078] With this design, the electronic components 220 of the controller 200 can be placed in the mounting slot 110g and directly contact the inner walls of the mounting slot 110g, such as the peripheral wall and bottom wall, for thermal conduction. The heat dissipation path of the electronic components 220 is shorter, which improves the heat dissipation efficiency of the electronic components 220, thereby improving the heat dissipation efficiency of the controller 200.

[0079] like Figure 1 , Figure 3 and Figure 4As shown, based on the same inventive concept, this application also provides a compressor housing 100, including: a compressor end cover 120 and the aforementioned compressor housing 110. The compressor end cover 120 is connected to the compressor housing 110 and together with the compressor housing 110 forms a high-pressure zone 110h. Along the axial direction X of the housing, a low-pressure zone 110a, a boosting zone 110b, and a high-pressure zone 110h are arranged sequentially, and the boosting zone 110b is also connected to the high-pressure zone 110h. The compressor end cover 120 has an exhaust port 120a that communicates with the high-pressure zone 110h.

[0080] The compressor end cover 120 is fixedly connected to the compressor housing 110, which can be done by snap-fit, bolt connection, or other means, and is not limited in this application. Since the compressor housing 100 includes the aforementioned compressor housing 110, it naturally has all the beneficial effects of the compressor housing 110, which will not be elaborated here.

[0081] like Figure 1 and Figure 2 As shown, based on the same inventive concept, this application also provides a compressor 1000. The compressor 1000 includes a controller 200 and further includes the aforementioned compressor housing 110 or the aforementioned compressor outer casing 100. The controller 200 is mounted on the heat-conducting surface 110f and makes heat-conducting contact with the heat-conducting surface 110f. Since the compressor 1000 includes the aforementioned compressor housing 110, it naturally possesses all the beneficial effects of the compressor housing 110, which will not be elaborated here.

[0082] In some embodiments, the controller 200 includes a housing 210 and electronic components 220. The housing 210 is mounted on a thermally conductive surface 110f and is in thermal contact with the thermally conductive surface 110f. The electronic components 220 are mounted on the housing 210 and are in thermal contact with the housing 210.

[0083] During the operation of the compressor 1000, the heat generated by the electronic components 220 is first transferred to the housing 210 of the controller 200, and then transferred to the heat-conducting surface 110f of the compressor housing 110 through the heat-conducting contact between the housing 210 and the heat-conducting surface 110f. At the same time, the refrigerant flows continuously along the flow channel 110e inside the compressor housing 110, quickly absorbing the heat from the heat-conducting surface 110f and carrying it out of the housing, forming a stable heat dissipation cycle.

[0084] like Figure 2 As shown, in some embodiments, the housing 210 includes a cover 211 and a body 212. The body 212 has a receiving groove. The cover 211 is placed on the receiving groove and is detachably connected to the body 212. The body 212 is fixedly connected to the heat-conducting surface 110f and is in heat-conducting contact. Electronic components 220 are installed in the receiving groove of the body 212 and are in heat-conducting contact with the body 212.

[0085] like Figure 2 and Figure 6 As shown, in some embodiments, a mounting groove 110g is provided on the heat-conducting surface 110f, and a clearance hole 210a is provided in the area of ​​the housing 210 opposite to the mounting groove 110g. At least some electronic components 220 of the controller 200 are located in the mounting groove 110g through the clearance hole 210a and are in heat-conducting contact with the inner wall of the mounting groove 110g.

[0086] With this design, the electronic components 220 of the controller 200 can pass through the clearance hole 210a and be placed in the mounting groove 110g, and directly make thermal contact with the inner walls such as the peripheral wall and bottom wall of the mounting groove 110g. The heat dissipation path of the electronic components 220 is shorter, which improves the heat dissipation efficiency of the electronic components 220, thereby improving the heat dissipation efficiency of the controller 200.

[0087] Based on the same inventive concept, this application also provides a refrigeration system, including the compressor 1000 described above.

[0088] Since this refrigeration system includes the aforementioned compressor 1000, it naturally possesses all the beneficial effects of the compressor 1000, which will not be elaborated upon here. The refrigeration system may also include a condenser, an evaporator, a throttling device (such as an expansion valve, capillary tube, etc.), and refrigerant pipelines connecting the various components. The components are connected in series through pipelines to form a closed refrigerant circulation loop. Through the phase change of the refrigerant, heat is transferred from the area requiring cooling (such as a car cabin or equipment heat dissipation area) to the external environment, thereby providing cooling capacity to the target area and meeting cooling or temperature control requirements.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
