[0047] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0048] Combination Figures 1 to 10According to an embodiment of the present invention, a thermal management device 100 includes a compressor 10, a first valve 31, a second valve 32, and a heat exchange liquid storage assembly 20. The first inlet of the first valve 31 is connected to the exhaust chamber 1011 of the compressor 10, the second inlet of the second valve 32 is connected to a bypass port of the first valve 31, and the second outlet of the second valve 32 is connected to the suction chamber 1012 of the compressor 10. The third inlet of the heat exchange liquid storage assembly 20 is connected to the first outlet of the first valve 31, and the third outlet of the heat exchange liquid storage assembly 20 is connected to the exhaust chamber 1011 of the compressor 10. The first valve 31 is configured to selectively direct the refrigerant in the exhaust chamber 1011 to the second inlet of the second valve 32 and the third inlet of the heat exchange liquid storage assembly 20. By adjusting the opening degree of the first valve 31, the exhaust pressure can be controlled. By controlling the exhaust pressure, the input power of the compressor 10 can be indirectly changed, thereby changing the cooling and heating power of the thermal management device 100.
[0049] The compressor 10 can draw in air from the suction chamber 1012 and deliver it out from the discharge chamber 1011 after compression. The compressor 10 is mainly composed of related compressor components that can compress low-pressure refrigerant into high-pressure refrigerant. The heat exchange liquid storage assembly 20 is mainly composed of related heat exchange components that can control temperature. This improves the integration and structural strength of the compressor 10 and the heat exchange liquid storage assembly 20, and also helps to improve the total volume of the internal flow path of the compressor 10 and the heat exchange liquid storage assembly 20, making it easier to reduce the amount of refrigerant added.
[0050] According to an embodiment of the present invention, the thermal management device 100 increases the total flow rate of refrigerant through the compressor 10 via the return flow channels of the first valve 31 and the second valve 32, thereby increasing the output power of the compressor 10 and improving the heating capacity of the system. Adjusting the opening degree of the first valve 31 can also adjust the discharge pressure of the compressor 10, thus increasing the output power of the compressor 10 and achieving rapid heating.
[0051] The first valve 31 and the second valve 32 of this invention can be electronic expansion valves, proportional valves, or throttle valves, etc. Furthermore, the thermal management device 100 of this invention can be used in vehicles or other equipment requiring temperature regulation. This invention is primarily described in the context of vehicles, but this is not a limitation on the scope of protection of this invention.
[0052] In a vehicle, the thermal management device 100 is mainly connected to the vehicle's functional systems and is used to control the temperature of the vehicle's functional systems. The vehicle's functional systems may be electric drive systems, battery systems, temperature control systems or dehumidification systems in the passenger compartment, etc. The thermal management device 100 uses the refrigerant in it to exchange heat and achieve effective temperature control of the entire vehicle's electric drive system, battery system and passenger compartment.
[0053] In some embodiments of the present invention, the thermal management device 100 has a first operating mode. In the first operating mode, the first valve 31 controls the refrigerant flow from the exhaust chamber 1011 to the third inlet of the heat exchange liquid storage assembly 20. Specifically, in the first operating mode, the thermal management device 100 operates in normal cooling and heating mode. The high-pressure refrigerant compressed by the compressor 10 passes through the first valve 31 (which can be fully open) and enters the heat exchange liquid storage assembly 20. The refrigerant exchanges heat with the coolant in the heat exchange liquid storage assembly 20 and uses the coolant to exchange heat with the functional systems in the vehicle, which can meet the normal cooling and heating conditions. In this mode, the second valve 32 can be kept closed, and the medium in the refrigerant flow path and the water flow path in the heat exchange liquid storage assembly 20 exchanges heat, which can meet the basic functions of the thermal management device 100.
[0054] Additionally, refer to Figure 3 and Figure 4 The thermal management device 100 also has a second operating mode. In this mode, the first valve 31 controls the refrigerant flow from the exhaust chamber 1011 to the third inlet of the heat exchange reservoir assembly 20 and the second inlet of the second valve 32. Specifically, in the second operating mode, the thermal management device 100 can meet extremely low temperature requirements. When the ordinary refrigerant circulation cannot meet the system's cooling and heating needs, a portion of the refrigerant from the exhaust chamber 1011 can pass through the first valve 31 (which can be partially open) and enter the heat exchange reservoir assembly 20. The refrigerant exchanges heat with the coolant in the heat exchange reservoir assembly 20 and utilizes the coolant to exchange heat with the functional systems in the vehicle. Finally, it returns to the intake chamber 1012. Another portion of the refrigerant from the exhaust chamber 1011 passes through the first valve 31 (partially open) and the second valve 32 (partially open) and also enters the intake chamber 1012, completing the heating cycle. In this mode, the second valve 32 can remain open to meet the extreme cooling requirements of the thermal management device 100. Figure 3 and Figure 4 The diagram shows the refrigerant circulation path.
[0055] In some embodiments, the compressor 10 has a first end 1021 and a second end 1022 opposite to each other along its axis. The second end 1022 of the compressor 10 may be provided with an intake port 1203 and an exhaust port 1204. The heat exchange liquid storage assembly 20 is connected to the compressor 10 and connects the exhaust port 1204 and the intake port 1203. Further, the heat exchange liquid storage assembly 20 and the compressor 10 are distributed along the axis of the compressor 10, and the intake port 1203 and the exhaust port 1204 are located on the end face of the second end 1022 of the compressor 10. This facilitates the connection of the compressor 10 to the heat exchange liquid storage assembly 20.
[0056] Combination Figures 1 to 13The present invention also provides a compressor 10, wherein the compressor 10 includes a housing body 11 and an exhaust distribution component 12, the exhaust distribution component 12 being connected to the housing body 11. The first valve 31 and the second valve 32 in the aforementioned embodiments can be disposed on the exhaust distribution component 12, and the heat exchange liquid storage assembly 20 is connected to the exhaust distribution component 12. The exhaust distribution component 12 can be used to distribute the refrigerant discharged by the compressor 10, improving the integration of the compressor 10 and facilitating the assembly and maintenance of the compressor 10.
[0057] In addition, such as Figures 5 to 13 The present invention also provides an exhaust distribution component 12 for connecting the aforementioned housing body 11. The exhaust distribution component 12 may have a first mounting cavity 1031 and an exhaust flow channel 1041, the exhaust flow channel 1041 connecting the exhaust cavity 1011 and the first mounting cavity 1031, and a first valve 31 disposed in the first mounting cavity 1031. The exhaust flow channel 1041 can deliver refrigerant from the exhaust cavity 1011 and guide the refrigerant delivered from the exhaust cavity 1011 to the first mounting cavity 1031. By providing the first mounting cavity 1031 in the exhaust distribution component 12, the integration of the compressor 10 can be improved, and the pipe size can be reduced, thereby reducing the amount of refrigerant, reducing the safety risks caused by refrigerant leakage, and improving the stability and safety of the thermal management device 100.
[0058] The exhaust chamber 1011 includes a lubricating oil separation chamber 1205, and an exhaust passage 1041 connects the lubricating oil separation chamber 1205 and the first mounting chamber 1031. The lubricating oil separation chamber 1205 separates refrigerant and lubricating oil. After being compressed by the compressor 10, the refrigerant is sent to the exhaust chamber 1011. Because the compressor 10 operates at a high speed, lubricating oil is necessary to improve its operational stability. However, with the lubricating oil, the refrigerant discharged from the compressor 10 inevitably carries some lubricating oil. This lubricating oil-laden refrigerant enters the exhaust chamber 1011 and then flows into the lubricating oil separation chamber 1205. The lubricating oil separates in the lubricating oil separation chamber 1205, while the refrigerant is discharged through the exhaust passage 1041 and sent to the first mounting chamber 1031. The first mounting chamber 1031 then controls the refrigerant flow direction. By providing the exhaust channel 1041, the refrigerant flow rate in the system can be increased, thereby improving the performance of the thermal management device 100. Furthermore, the lubricating oil separation chamber 1205 can separate the lubricating oil carried in the refrigerant, increasing the amount of refrigerant in the refrigerant flow path and improving the operating performance of the compressor 10. Simultaneously, the separated lubricating oil can be easily returned to the compressor 10 for lubrication of the compression unit 14 within the compressor 10, thereby reducing the amount of lubricating oil used in the thermal management device 100.
[0059] Optionally, the exhaust channel 1041 is a straight channel extending obliquely from bottom to top. The lower end of the exhaust channel 1041 connects to the lubricating oil separation chamber 1205, and the upper end of the exhaust channel 1041 forms a first mounting cavity 1031, which penetrates the outer surface of the exhaust distribution member 12. Furthermore, the exhaust distribution member has a first cylindrical portion, within which the lubricating oil separation chamber can be located. Since the upper end of the exhaust channel penetrates the outer surface of the exhaust distribution member 12, the exhaust channel can be constructed by drilling holes in the outer surface of the exhaust distribution member 12. Moreover, the open upper end of the exhaust channel facilitates the installation of the first valve 31 within the first mounting cavity 1031, simplifying the assembly structure of the first valve 31. The installation of the first valve 31 can also close the opening of the exhaust channel 1041, improving the integration of the compressor 10.
[0060] In addition, the exhaust distribution component 12 has an exhaust port 1204 on its end face, which connects to the first mounting cavity 1031 and the third inlet of the heat exchange liquid storage assembly 20. The exhaust port 1204 facilitates the connection between the exhaust distribution component 12 and the heat exchange liquid storage assembly 20, simplifying the piping layout of the thermal management device 100 and facilitating its production, assembly, and maintenance. Furthermore, the exhaust distribution component 12 can be integrated with the heat exchange liquid storage assembly 20 into a single structure. For example, the exhaust distribution component 12 and the heat exchange liquid storage assembly 20 can be stacked and connected along the axis of the compressor 10. In this case, the exhaust port 1204 can connect with the third inlet of the heat exchange liquid storage assembly 20 along the axis of the compressor 10, further simplifying the structure of the thermal management device 100 and facilitating installation. Additionally, it can reduce the length of the refrigerant piping and decrease the amount of refrigerant used.
[0061] Combination Figures 11 to 13 In some embodiments, the exhaust distribution component 12 is provided with a second mounting cavity 1032 and a first bypass channel 1201. The first bypass channel 1201 connects the first mounting cavity 1031 and the second mounting cavity 1032, and the second valve 32 is disposed in the second mounting cavity 1032. The first bypass channel 1201 can be used to allow refrigerant to flow from the first mounting cavity 1031 to the second mounting cavity 1032. Thus, when the first inlet in the first valve 31 is connected to the bypass interface, the refrigerant delivered from the exhaust cavity 1011 will flow from the exhaust passage into the first bypass channel 1201, thereby using the first bypass channel 1201 to bypass the refrigerant, so as to improve the refrigerant return volume and optimize the performance of the thermal management device 100.
[0062] Optionally, the exhaust channel 1041 is configured as a straight channel. One end of the first bypass channel 1201 penetrates the outer surface of the exhaust separator and forms a first mounting base 1051 for mounting the first sensor 61. The first sensor 61 is used to monitor the exhaust pressure and temperature of the compressor 10 as an input signal for system regulation. The other end of the first bypass channel 1201 is connected to the second mounting cavity 1032. Since one end of the first bypass channel 1201 penetrates the outer surface of the exhaust distributor 12, an exhaust channel can be constructed by drilling holes in the outer surface of the exhaust distributor 12. Moreover, by opening the first bypass channel 1201, it is convenient to install the first sensor 61 at the open end of the first bypass channel 1201. This not only enables the closure of the open section of the first bypass channel 1201 to seal the refrigerant and prevent leakage, but also enables stable detection of the operating status of the compressor 10 and rapid understanding of the operating condition of the compressor 10.
[0063] Optionally, the first bypass channel 1201 and the exhaust channel 1041 intersect and connect, and the first mounting cavity 1031 is located at the intersection of the first bypass channel 1201 and the exhaust channel 1041. In this way, when the first valve 31 is located in the first mounting cavity 1031, it is convenient to connect the first inlet of the first valve 31 to the exhaust channel, and to facilitate the bypass interface of the first valve 31 to connect to the second valve 32, thereby simplifying the structure of the first valve 31 and facilitating the flow of refrigerant. Furthermore, in conjunction with the aforementioned embodiment, the exhaust distribution component 12 is provided with an exhaust port 1204, which is used to connect to the third inlet of the heat exchange liquid storage assembly 20. The exhaust port 1204 can be located at the intersection of the first bypass channel 1201 and the exhaust channel 1041, thereby further facilitating the installation of the first valve 31 and the switching of the flow path of the first valve 31.
[0064] In some examples, the first mounting cavity 1031 and the second mounting cavity 1032 are distributed circumferentially along the exhaust distribution member 12. This facilitates the installation and assembly of the first valve 31 and the second valve 32, and also optimizes the integration of the thermal management device 100. The first mounting cavity 1031 and the second mounting cavity 1032 can be located on the outer peripheral surface of the exhaust distribution member 12.
[0065] like Figures 11 to 13The exhaust distribution component 12 is provided with a second bypass channel 1202 and an intake port 1203. The second bypass channel 1202 connects the second mounting cavity 1032 and the intake port 1203, and the intake port 1203 connects to the third outlet of the heat exchange liquid storage assembly 20. The second bypass channel 1202 allows refrigerant to flow from the second mounting cavity 1032 to the intake port 1203. When the first inlet in the first valve 31 is connected to the bypass interface, the refrigerant delivered from the exhaust cavity 1011 will flow from the exhaust passage into the first bypass channel and the second bypass channel 1202, thereby achieving refrigerant bypass using the second bypass channel 1202 to improve the refrigerant return volume and optimize the performance of the thermal management device 100. Additionally, the intake port 1203 can be configured to penetrate the exhaust distribution component 12.
[0066] Optionally, the second bypass channel 1202 is configured as a straight channel, with one end penetrating the outer surface of the exhaust distribution member 12 and having a first plug 51, and the other end connecting to the second mounting cavity 1032. Since one end of the second bypass channel 1202 penetrates the outer surface of the exhaust distribution member 12, the second bypass channel 1202 can be constructed by drilling holes in the outer surface of the exhaust distribution member 12. Furthermore, the open end of the second bypass channel 1202 can be sealed by the first plug 51 to prevent refrigerant leakage.
[0067] In addition, the first bypass channel 1201 and the second bypass channel 1202 are distributed circumferentially along the exhaust distribution member 12. The first bypass channel 1201 and the second bypass channel 1202 may be configured to have an included angle, and the second mounting cavity 1032 is provided at the connection between the first bypass channel 1201 and the second bypass channel 1202.
[0068] In conjunction with the foregoing, the exhaust distribution component 12 is provided with an exhaust flow channel 1041, a first mounting cavity 1031, a first bypass flow channel 1201, a second mounting cavity 1032, a second bypass flow channel 1202, an exhaust port 1204, and an intake port 1203. The exhaust flow channel 1041 is connected to the first mounting cavity 1031, the first bypass flow channel 1201 is connected to the first mounting cavity 1031 and the second mounting cavity 1032, the second bypass flow channel 1202 is connected to the second mounting cavity 1032, the exhaust port 1204 is connected to the first mounting cavity 1031, and the intake port 1203 is connected to the second bypass flow channel 1202.
[0069] In addition, the exhaust distribution component 12 is also provided with a first cylindrical portion 121. In the orthographic projection along the axis of the compressor 10, a first mounting cavity 1031 and a second mounting cavity 1032 are disposed around the first cylindrical portion 121. This facilitates the installation of the first valve 31 in the first mounting cavity 1031 and the installation of the second valve 32 in the second mounting cavity 1032, providing sufficiently large accommodating space for the first valve 31 and the second valve 32, and ensuring that the exhaust distribution component 12 has sufficient wall thickness to improve the stability and safety of the compressor 10.
[0070] Optionally, the air intake 1203 and the exhaust 1204 are located on the end face of the exhaust distribution component 12 to facilitate connection to the heat exchange liquid storage assembly 20.
[0071] Additionally, the thermal management device 100 having the exhaust distribution component 12 includes a compressor 10, a first valve 31, a second valve 32, and a heat exchange liquid storage assembly 20. The first valve 31 is located in the first mounting cavity 1031; the second valve 32 is located in the second mounting cavity 1032; the heat exchange liquid storage assembly 20 is connected to the exhaust port 1204 and the intake port 1203. The first valve 31 is configured to selectively direct the refrigerant discharged from the compressor 10 to the second valve 32 and the heat exchange liquid storage assembly 20.
[0072] Combination Figures 5 to 13 In some embodiments of the present invention, the exhaust distribution component 12 is further provided with a second mounting base 1052 and a viewing window channel 1206. The second mounting base 1052 is used to install the transparent viewing window 122, and the viewing window channel 1206 is a straight channel. One end of the viewing window channel 1206 is connected to the lower space of the exhaust chamber 1011, and the other end is connected to the second mounting base 1052. By providing the second mounting base 1052 and the viewing window channel 1206, the transparent viewing window 122 can be installed on the second mounting base 1052, thereby facilitating the observation of the internal condition of the exhaust distribution component 12 through the transparent viewing window 122, so as to facilitate timely replenishment of refrigerant, lubricating oil, etc., and also to facilitate the maintenance of the thermal management device 100.
[0073] Combination Figures 5 to 13 In some embodiments of the present invention, the exhaust distribution member 12 and the housing body 11 are distributed along the axis of the compressor 10. This facilitates the connection between the compressor 10 and the heat exchange liquid storage assembly 20 and improves the integration of the thermal management device 100. In addition, the exhaust distribution member 12 can be configured as an integral structure with at least a part of the housing body 11; the exhaust distribution member 12 can also be configured as a separate structure from the housing body 11.
[0074] Optionally, the heat exchange liquid storage assembly 20 and the exhaust distribution component 12 are distributed and connected along the axis of the compressor 10. This facilitates the connection between the exhaust distribution component 12 and the heat exchange liquid storage assembly 20, and shortens the piping between the exhaust distribution component 12 and the heat exchange liquid storage assembly 20, thereby reducing refrigerant consumption. Optionally, the housing body 11, the exhaust distribution component 12, and the heat exchange liquid storage assembly 20 are distributed and connected along the axis of the compressor 10, and the exhaust distribution component 12 is connected between the housing body 11 and the heat exchange liquid storage assembly 20.
[0075] Optionally, the exhaust distribution component 12 has a first cylindrical portion 121, and the shell body 11 has a second cylindrical portion 114, with the second cylindrical portion 114 passing through the first cylindrical portion 121. The first cylindrical portion 121 surrounds the second cylindrical portion 114, achieving a stable connection between the shell body 11 and the exhaust distribution component 12, and effectively sealing the exhaust distribution component 12 and the shell body 11. This improves the stability and sealing effect of the connection, thereby preventing refrigerant leakage and enhancing the stability and safety of the thermal management device 100.
[0076] In some examples, the exhaust distribution component 12 and the housing body 11 are separate yet connected as a single unit. Designing the exhaust distribution component 12 and housing body 11 as separate units simplifies their structure and reduces the manufacturing and assembly difficulty of the thermal management device 100. Conversely, connecting the exhaust distribution component 12 and housing body 11 as a single unit allows for the connection of the heat exchange reservoir assembly 20 or the vehicle after the exhaust distribution component 12 and housing body 11 are assembled, simplifying the installation process of the thermal management device 100, reducing costs, and improving stability.
[0077] Optionally, a second sealing ring 73 is provided between the exhaust distribution component 12 and the housing body 11. This can achieve an effective seal between the exhaust distribution component 12 and the housing body 11, improve the stability and sealing performance of the thermal management device 100, and prevent refrigerant leakage.
[0078] In some embodiments, the compressor 10 further includes a plurality of first fixing members distributed circumferentially along the compressor 10, which fix the exhaust distribution member 12 and the housing body 11. The first fixing members can be fixing bolts. The plurality of first fixing members can achieve uniform circumferential connection between the exhaust distribution member 12 and the housing body 11, improving the sealing performance between them and ensuring a stable connection.
[0079] like Figures 1 to 4In some embodiments of the present invention, the compressor 10 and the heat exchange liquid storage assembly 20 are distributed along the axis of the compressor 10. This facilitates the connection between the compressor 10 and the heat exchange liquid storage assembly 20 and improves the integration of the thermal management device 100. Additionally, the exhaust distribution member 12 can be configured as an integral structure with at least a portion of the housing body 11; alternatively, the exhaust distribution member 12 can be configured as a separate structure from the housing body 11.
[0080] Optionally, the heat exchanger assembly 20 and the compressor 10 are stacked and connected as a single unit. Designing the heat exchanger assembly 20 and the compressor 10 as separate units simplifies their structure and reduces the manufacturing and assembly difficulty of the thermal management device 100. Furthermore, connecting the heat exchanger assembly 20 and the compressor 10 as a single unit allows for assembly of the two components before connection to the vehicle, simplifying the installation process, reducing costs, and improving stability. Additionally, the stacked arrangement of the heat exchanger assembly 20 and the compressor 10 shortens the flow path and reduces refrigerant consumption.
[0081] Optionally, a first sealing ring 73 is provided between the heat exchange liquid storage assembly 20 and the compressor 10. This can achieve effective sealing between the heat exchange liquid storage assembly 20 and the compressor 10, improve the stability and sealing performance of the thermal management device 100, and prevent refrigerant leakage.
[0082] In some examples, the thermal management device 100 further includes a plurality of second fasteners distributed circumferentially along the compressor 10, which fix the compressor 10 and the heat exchange liquid storage assembly 20. The second fasteners can be fixing bolts, and the multiple second fasteners can achieve a uniform circumferential connection between the compressor 10 and the heat exchange liquid storage assembly 20, improving the sealing between them and ensuring a stable connection.
[0083] In addition, such as Figures 5 to 10 The present invention also provides a compressor 10 of a thermal management device 100, wherein the compressor 10 has a first end 1021 and a second end 1022 opposite to each other along an axis, the compressor 10 has an intake chamber 1012 located at the first end 1021, and an exhaust chamber 1011 located at the second end 1022, and the second end 1022 has an intake port 1203. The intake port 1203 may be configured to connect to the third outlet of the aforementioned heat exchange liquid storage assembly 20 and the second outlet of the second valve 32.
[0084] The compressor 10 includes a first housing portion 111 and a second housing portion 112. A compression unit 14 is housed within the first housing portion 111, and the second housing portion 112 is located outside the first housing portion 111. An air intake passage 1042 is located within the second housing portion 112. One end of the air intake passage 1042 is connected to an air intake port 1203, and the other end is connected to an air intake chamber 1012. By placing the air intake passage 1042 externally, the volume of the compressor 10 can be reduced, space utilization improved, and the internal flow path of the compressor 10 simplified, thereby simplifying the structure of the first housing portion 111 and facilitating refrigerant flow.
[0085] In some embodiments, the first housing portion 111 extends along the axis of the compressor 10, and the second housing portion 112 extends parallel to the axis of the compressor 10. This can reduce flow resistance during refrigerant flow and improve the performance of the thermal management device 100.
[0086] Optionally, the compressor 10 further includes a third housing portion 113 connected to the first housing portion 111 and the second housing portion 112. The third housing portion 113 can improve the connection strength between the first housing portion 111 and the second housing portion 112. The axis of the first housing portion 111 and the axis of the second housing portion 112 can be parallel to each other and extend along the axis of the compressor 10. The third housing portion 113 can also be a plate extending along the axis of the compressor 10, and a plate extending radially and axially along the first housing portion 111.
[0087] like Figures 5 to 10 In some embodiments, the compressor 10 has a low-pressure housing 13 at its first end 1021 and an exhaust distribution member 12 at its second end 1022. The low-pressure housing 13 has a connecting channel that connects the intake chamber 1012 and the intake channel 1042. A first housing portion 111 is connected between the low-pressure housing 13 and the exhaust distribution member 12, and a second housing portion 112 is also connected between the low-pressure housing 13 and the exhaust distribution member 12. This simplifies the structure of the compressor 10 and improves its stability and structural strength.
[0088] The connecting channel includes a first channel 1301, which is located outside the suction chamber 1012. The first channel 1301 can be used to connect the suction channel 1042 and the suction chamber 1012, and connect the suction chamber 1012 with the lower space of the suction chamber 1012, so that the compression unit 14 can draw air from the suction chamber 1012.
[0089] The connecting channel also includes a second channel 1302, which connects the first channel 1301 and the suction chamber 1012. The second channel 1302 can be used to guide the refrigerant located in the first channel 1301 outside the suction chamber 1012 to the suction chamber 1012, so as to facilitate the suction of the suction chamber 1012.
[0090] In some embodiments, the first channel 1301 is a straight channel extending in a direction perpendicular to the axis of the compressor 10. One end of the first channel 1301 penetrates the outer surface of the low-pressure housing 13 and is provided with a second plug 52. This facilitates the forming of the first channel 1301, simplifies the structure of the low-pressure housing 13, and reduces the difficulty of processing the low-pressure housing 13. The first channel 1301 can be constructed by drilling holes in the outer surface of the low-pressure housing 13, and the open end of the first channel 1301 can be closed by the second plug 52 to prevent refrigerant leakage.
[0091] Optionally, the first channel 1301 extends in the vertical direction.
[0092] In some embodiments, the second channel 1302 is a straight channel extending in a direction perpendicular to the axis of the compressor 10. One end of the second channel 1302 penetrates the outer surface of the low-pressure housing 13 and is provided with a third plug 53. This facilitates the forming of the second channel 1302, simplifies the structure of the low-pressure housing 13, and reduces the processing difficulty of the low-pressure housing 13. The second channel 1302 can be constructed by drilling holes in the outer surface of the low-pressure housing 13, and the open end of the second channel 1302 can be closed by the third plug 53 to prevent refrigerant leakage.
[0093] Optionally, the second channel 1302 connects to the lower part of the intake chamber 1012, which facilitates the intake of air by the compressor 10.
[0094] In some embodiments, the low-pressure housing 13 is further provided with a third mounting cavity 1033, which is connected to a connecting flow channel. The compressor 10 also includes a refrigerant charging valve 34, which is located in the third mounting cavity 1033. The refrigerant charging valve 34 allows for convenient charging of refrigerant into the compressor 10, simplifying the processing and assembly of the thermal management device 100, improving its stability and cooling / heating capacity, reducing energy consumption, and promoting energy conservation and environmental protection. The refrigerant charging valve 34 can be used for vacuuming the compressor 10 and charging the refrigerant.
[0095] In some embodiments, the low-pressure housing 13 is further provided with a fourth mounting cavity 1034, which is connected to a flow channel. The compressor 10 also includes a second sensor 62, which is disposed in the fourth mounting cavity 1034. The second sensor 62 can be configured to detect the refrigerant temperature and pressure in the suction chamber 1012, the suction flow channel 1042, etc., in order to facilitate the control of the thermal management system.
[0096] In some embodiments, the first end of the compressor 10 is provided with an electronic control cavity for mounting electronic devices. Electronic devices, the electronic control cavity, etc., can be integrated into the compressor 10, increasing the integration level of the compressor 10 and reducing its size.
[0097] Furthermore, the electronic device includes a high-voltage connector 133, which is installed in and extends out of the electrical control cavity for connecting a high-voltage wiring harness; and / or, the electronic device includes a low-voltage connector 134, which is installed in and extends out of the electrical control cavity for connecting a low-voltage wiring harness; and / or, the electronic device includes a stator connector, which is installed in and extends out of the electrical control cavity for connecting a stator 151; and / or, the electronic device includes an integrated circuit board 161, which is installed in the electrical control cavity and electrically connects the high-voltage connector 133 and the low-voltage connector 134. A stator connector mounting hole 1306 is designed on the low-voltage housing 13 for sealing and insulating the stator connector from the low-voltage housing 13. Through the stator connector mounting hole 1306, communication and conductivity between the integrated circuit board 161 and the stator 151 can be achieved.
[0098] Optionally, the first end 1021 of the compressor 10 is provided with an end plate 131 and an end cover 132 covering the end plate 131. The end cover 132 is farther away from the second end 1022 of the compressor 10 than the end plate 131. The end plate 131 is provided with a high-pressure connector mounting hole 1304, a low-pressure connector mounting hole 1305, a stator connector mounting hole 1306, a power device heat dissipation surface 1303 and / or a cover plate mounting hole 1307. The high-pressure connector mounting hole 1304 and the low-pressure connector mounting hole 1305 penetrate the end plate 131 and are located outside the suction chamber 1012. The low-pressure connector 134 can be located in the low-pressure connector mounting hole 1305, and the high-pressure connector 133 can be located in the high-pressure connector mounting hole 1304. Since the low-pressure connector mounting holes 1305 and 1304 penetrate the end plate 131, the wiring ports of the high-pressure connector 133 and the low-pressure connector 134 can be located on the side of the end plate 131 facing the second end 1022. This facilitates the wiring of the compressor 10, reduces the space occupied by the compressor 10, and improves space utilization. The heat generated by the power module 162 on the integrated circuit board 161 is efficiently conducted through the heat dissipation surface 1303 of the power device. The heat conducted to the low-pressure housing 13 is released into the refrigerant through convection heat exchange between the low-pressure housing 13 and the refrigerant.
[0099] In addition, the end plate 131 is also provided with stator connector mounting holes 1306, power device heat dissipation surface 1303 and / or cover plate mounting holes 1307. This facilitates the installation of electronic components, circuit boards, etc., and heat dissipation of power devices, thereby improving the stability of compressor 10 operation and optimizing compressor 10 performance.
[0100] In addition, the end face formed by the second end 1022 is in contact with the surface of the heat exchange liquid storage assembly 20, so that the exhaust port 1204 and the suction port 1203 integrated in the second end 1022 are connected to the refrigerant flow path on the heat exchange liquid storage assembly 20, ensuring the normal circulation of refrigerant in the thermal management device 100, while reducing the use of connecting pipes and reducing the overall volume of the thermal management device 100; the compressor 10 and the heat exchange liquid storage assembly 20 are integrated and assembled by means such as bolt connection, snap connection, and plug connection, improving the connection reliability of the compressor 10 and the heat exchange liquid storage assembly 20, and thereby further ensuring the circulation reliability of the internal refrigerant.
[0101] The first end 1021 is used to connect to the vehicle power supply. When the first end 1021 and the second end 1022 are arranged opposite each other, that is, when the heat exchange liquid storage assembly 20 is located on the side of the compressor 10 away from the first end 1021, the installation space on that side is reasonably utilized. In other words, the space occupied on other sides of the thermal management device 100 can be effectively reduced, freeing up space for the assembly of other components and reducing interference. Of course, in other embodiments, depending on the specific distribution of the exhaust port 1204 and the intake port 1203 of the compressor 10, the heat exchange liquid storage assembly 20 can partially surround the compressor 10 or be connected to the periphery of the compressor 10.
[0102] The first end 1021 is provided with a connector for connecting to the power supply. The connector includes a high-voltage connector 133 and a low-voltage connector 134 arranged at intervals from top to bottom.
[0103] In some embodiments, the compressor 10 is provided with an electric unit and a compression unit 14. The electric unit is located inside the first housing portion 111. The electric unit includes a stator 151, a rotor 152 and a main shaft 153. The main shaft 153 is connected to the rotor 152. The stator 151 drives the rotor 152 to rotate. The main shaft 153 is connected to the compression unit 14. One end of the main shaft 153 is connected to the compression unit 14 and is provided with a first balance block 154. And / or, one end of the rotor 152 is away from the compression unit 14 and is provided with a second balance block 155.
[0104] In conjunction with the foregoing, the compressor 10 of the present invention may include: a low-pressure housing 13, a low-pressure connector 134, a high-pressure connector 133, an end cover 132, a mounting bracket 74, an exhaust distribution component 12, etc.
[0105] The high-voltage connector 133 connects to the vehicle's high-voltage wiring harness to provide high-voltage electricity to the compressor 10 and implements the interlock function of the high-voltage system. The low-voltage connector 134 connects to the vehicle's low-voltage wiring harness to provide low-voltage control signals to the compressor 10. The vehicle controls the compressor 10 and receives feedback signals from the compressor 10 through the low-voltage connector 134. The integrated circuit board 161 receives the control signals from the low-voltage connector 134 and converts the DC power from the high-voltage connector 133 into AC power with adjustable frequency and voltage, generating a rotating magnetic field through the stator coil 151. The rotor 152 rotates under the action of the rotating magnetic field, and the rotational motion occurs around the axis formed by the first bearing 173 and the second bearing 174. A first balance block 154 and a second balance block 155 are installed at the ends of the main shaft 153 and the rotor 152, respectively. The first balance block 154 and the second balance block 155 counteract the unbalanced forces generated by the movement of the rotor 152 and the compression unit 14, reducing the vibration of the compressor 10.
[0106] The compression unit 14 may include a stationary scroll and a moving scroll. The stationary scroll is stationary relative to the housing body 11, and the moving scroll and rotor 152 are connected together via a main shaft 153. The moving scroll undergoes helical translation under the drive of the rotor 152. Refrigerant enters and exits the compressor 10 through the exhaust distribution component 12. The exhaust distribution component 12 is machined with an exhaust port 1204 and an intake port 1203. The refrigerant enters the compressor 10 through the intake port 1203 and exits the compressor 10 through the exhaust port. In this invention, the first plug 51, the exhaust distribution component 12, the second plug 52, and the third plug 53 are connected and fixed to the low-pressure housing 13 by welding or by threading and adding a sealing ring 73.
[0107] Optionally, the low-pressure housing 13 is designed with a first bearing bracket 171, in which a first bearing 173 is installed, supporting the end of the main shaft 153. The low-pressure housing 13 is also designed with a second bearing bracket 172, in which a second bearing 174 is installed, supporting the end of the main shaft 153. A mounting bracket 74 is designed on the low-pressure housing 13 for fixing the compressor 10 assembly to the vehicle. An accessory bracket and accessory mounting holes 701 are designed on the low-pressure housing 13 for fixing other accessories on the refrigeration system.
[0108] The refrigerant enters the suction channel 1042 through the suction port 1203, and then enters the low-pressure chamber of the compressor 10. Within the low-pressure chamber, it flows through the stator 151 and rotor 152 of the motor before entering the compressor 10 chamber formed by the moving and stationary scroll plates. The refrigerant is compressed within the moving and stationary scroll plates. High-pressure refrigerant gas is discharged from the central exhaust port of the stationary scroll plate. The refrigerant forces open the exhaust valve plate 141 and enters the exhaust distribution component 12. In the oil distribution channel of the exhaust distribution component 12, the refrigerant and lubricating oil are separated. The separated lubricating oil flows through the oil return hole to the vicinity of the second bearing 174 to lubricate it. The end of the oil distribution channel connects to the first valve 31 and the exhaust port 1204, and the exhaust pressure is regulated by the first valve 31. The exhaust port 1204 connects to an external heat exchanger to achieve heat and mass transfer between the refrigerant and the refrigeration system.
[0109] The integrated circuit board 161 receives the control signal from the low-voltage connector 134 and converts the DC power from the high-voltage connector 133 into AC power with adjustable frequency and voltage, which generates a rotating magnetic field through the stator coil 151. The rotor 152 rotates under the action of the rotating magnetic field, and the rotational motion occurs around the axis formed by the first bearing 173 and the second bearing 174.
[0110] In the technical solution of this invention, the integrated assembly of the thermal management device 100 and the internal flow path are achieved by directly connecting the compressor 10 and the heat exchange liquid storage component 20. This ensures that the thermal management device 100 can achieve temperature control of the vehicle's functional systems. Moreover, compared with connecting pipes to connect various components, the number of connecting pipes can be reduced, the integration of the thermal management device 100 can be improved, and the total volume of the flow path inside the thermal management device 100 can be reduced, thus reducing the risk of refrigerant leakage. At the same time, the amount of refrigerant added can be significantly reduced and the structural strength of the device can be increased, thereby improving the safety of the thermal management system. In addition, the assembly method of integrating the two major assemblies can save the assembly time of the thermal management system and meet the requirements of the graded assembly of the main assembly line.
[0111] like Figure 1 and Figure 2The present invention also provides a heat exchange reservoir assembly 20, which includes a reservoir 21 and at least one heat exchanger. The reservoir 21 and at least one heat exchanger are integrated into a single unit. Furthermore, by integrating the heat exchange reservoir assembly 20 into a single unit, the assembly of the thermal management device 100 and the connection of its internal flow paths are achieved. Compared to using connecting pipes to connect various components, this reduces the number of connecting pipes, increases the integration of the thermal management device 100, thereby reducing the total volume of the flow channels within the thermal management device 100, lowering the risk of refrigerant leakage, and significantly reducing the amount of refrigerant added while increasing the structural strength of the device, improving the safety of the thermal management system, and saving assembly time for the thermal management system and meeting the requirements of graded assembly on the final assembly line. The reduction in refrigerant added increases the safety of the flammable and explosive thermal management system, improving the overall vehicle safety level.
[0112] Optionally, the receiver 21 and at least one heat exchanger are stacked along the axis of the compressor 10. This simplifies the flow path within the heat exchange assembly and reduces flow resistance. Additionally, the receiver 21 may integrate a desiccant and / or a filter, thereby improving the operating performance of the heat exchange receiver assembly 20, increasing the proportion of gaseous refrigerant in the refrigerant flow path, and optimizing the performance of the compressor 10.
[0113] Optionally, the liquid receiver 21 and at least one heat exchanger are integrated into a single unit by welding or bolting. This improves the stability and structural strength of the heat exchange liquid receiver assembly 20, ensures the sealing between components, and prevents refrigerant leakage, thereby enhancing the stability and safety of the heat exchange liquid receiver assembly 20. Furthermore, refrigerant flow is achieved between adjacent units of the liquid receiver 21 and at least one heat exchanger through internal flow channels.
[0114] In some embodiments, a first observation window 211 is provided at the bottom of the reservoir 21; and / or, a second observation window 212 is provided on the side of the reservoir 21. The first observation window 211 and the second observation window 212 are used to observe the refrigerant state inside the reservoir 21 and at the outlet of the reservoir 21. This allows for convenient observation of the internal state of the reservoir 21, facilitating the assembly and maintenance of the thermal management device 100.
[0115] The heat exchange liquid storage assembly 20 has independent refrigerant and coolant flow paths. The second end 1022 of the compressor 10 has an exhaust port 1204 and an intake port 1203. The refrigerant flow path connects to the compressor 10 through the exhaust port 1204 and intake port 1203, allowing the refrigerant in the compressor 10 to flow into the refrigerant flow path of the heat exchange liquid storage assembly 20 through the exhaust port 1204 and exchange heat with the coolant in the coolant flow path. After heat exchange, the refrigerant re-enters the compressor 10 through the intake port 1203, completing one cycle. Optionally, the refrigerant flow path is located between the third inlet and the third outlet.
[0116] The heat exchange reservoir assembly 20 has at least one coolant flow path, each coolant flow path corresponds to a functional system, and each is connected in a closed loop with the refrigerant flow path. In this way, the refrigerant in one refrigerant flow path exchanges heat with the coolant in multiple coolant flow paths, thereby achieving effective temperature control of the vehicle's electric drive system, battery system, and passenger compartment. This helps to improve the functional integration of the heat exchange reservoir assembly 20, further simplify the system flow path, and reduce costs.
[0117] Each heat exchanger corresponds to a specific functional system, enhancing the functional integration of the heat exchange and storage assembly 20. Utilizing the structural characteristics of the heat exchanger—namely, the closely arranged plates forming channels where the hot and cold fluids do not communicate—the heat exchanger occupies less floor space compared to other types. Thus, in conjunction with the layered arrangement of the storage tank 21, the space occupied by the heat exchange and storage assembly 20 can be reduced to a certain extent. Simultaneously, effective temperature control is achieved through heat exchange between the refrigerant and coolant entering the heat exchange and storage assembly 20. The storage tank 21 and the heat exchanger assembly can be integrally connected using methods such as brazing.
[0118] In some embodiments, at least one heat exchanger includes a condenser 22 and an evaporator 23, with a liquid receiver 21 located between the condenser 22 and the evaporator 23. Specifically, the heat exchanger assembly includes a condenser 22 and an evaporator 23 stacked together, with the liquid receiver 21 located between the condenser 22 and the evaporator 23. Since the refrigerant flowing out of the condenser 22 is in a two-phase state, the liquid and gaseous refrigerants can be separated in the liquid receiver 21 using its built-in flow channels. Then, the liquid refrigerant flows out through the bottom corner holes of the liquid receiver 21 and flows to the evaporator 23, ensuring the evaporation rate of the evaporator 23, ensuring that the refrigerant expands in the evaporator 23 and fully absorbs the heat of the coolant, and improving the heat exchange efficiency between the refrigerant flow path and the coolant flow path.
[0119] Placing the liquid receiver 21 between the condenser 22 and the evaporator 23, and rationally designing the flow paths between the liquid receiver 21, the condenser 22 and the evaporator 23, ensures that the connecting flow paths between the condenser 22 and the liquid receiver 21, and between the liquid receiver 21 and the evaporator 23 are as short as possible. This helps to simplify the flow paths within the heat exchange liquid receiver assembly 20, avoid excessive pressure and heat loss due to excessively long flow paths, and improve the smoothness of refrigerant flow and the heat exchange efficiency with the corresponding coolant.
[0120] The coolant flow path through the condenser 22 can be used to control the temperature and humidity inside the passenger compartment. The coolant flow path through the evaporator 23 can be used to control the temperature of the battery system and the temperature and humidity inside the passenger compartment. The remaining coolant flow paths can be equipped with additional heat exchangers or independent external radiators to control the temperature of the electric drive system, so that all functional systems of the vehicle can achieve good operating conditions, ensuring the driving and riding comfort of the driver and passengers, and also ensuring the stable and reliable operation of the vehicle.
[0121] In some embodiments, the liquid reservoir 21 is provided with a gas-liquid separation unit connected in series between the condenser 22 and the evaporator 23.
[0122] Optionally, at least one heat exchanger further includes a subcooler 24, which is connected in series between the condenser 22 and the evaporator 23. Alternatively, the subcooler 24 may be located between the condenser 22 and the liquid receiver 21; or the subcooler 24 may be located between the evaporator 23 and the liquid receiver 21. The subcooler 24 allows for secondary heat exchange between the condensed saturated liquid and the coolant, further increasing the subcooling of the refrigerant, reducing flash gas generated during throttling, and thus helping to increase the evaporation rate of the evaporator 23 and improve heat exchange efficiency.
[0123] like Figures 1 to 2 The subcooler 24 is located between the liquid receiver 21 and the condenser 22. The subcooler 24 has a through hole for connecting the condenser outlet of the condenser 22 and the condenser inlet of the liquid receiver 21, serving as a channel connecting the condenser 22 and the liquid receiver 21. This ensures that the refrigerant flowing out of the condenser 22 can pass through the subcooler 24 (without heat exchange) and enter the liquid receiver 21, achieving separation of the liquid and gaseous refrigerants. The liquid receiver 21 also has a bottom corner hole for connecting to the subcooling inlet of the subcooler 24, ensuring that the liquid refrigerant flows sequentially through the bottom corner hole and the subcooling inlet into the subcooler 24 for secondary heat exchange, and flows out of the subcooler 24 through the subcooling outlet. The subcooling outlet connects to the throttling inlet of a throttling device, such as an expansion valve. Alternatively, in other embodiments, the subcooler 24 is located between the liquid receiver 21 and the evaporator 23.
[0124] In some embodiments, the heat exchange liquid storage assembly 20 further includes a third valve 33, which is connected in series between the condenser 22 and the evaporator 23. The third valve 33 is used to control the flow of refrigerant from the condenser 22 to the evaporator 23. The third valve 33 is located at the inlet of the evaporator 23. On the one hand, it controls the flow rate of refrigerant into the evaporator 23, ensuring that the refrigerant flowing out of the outlet of the evaporator 23 is in a gaseous state, reducing the liquid refrigerant content, thereby reducing the possibility of liquid slugging when the refrigerant enters the compressor 10, and avoiding insufficient cooling due to insufficient refrigerant flow, ensuring the cooling capacity of the evaporator 23 and improving the heat exchange efficiency. On the other hand, it can throttle the low-temperature and high-pressure liquid refrigerant through the throttling orifice of the third valve 33 to become a low-temperature and low-pressure mist-like liquid refrigerant, meeting the evaporation conditions of the liquid refrigerant, thereby improving the evaporation heat absorption efficiency.
[0125] To further improve the integration of the heat exchange reservoir assembly 20, in one embodiment, the third valve 33 is integrated into the reservoir 21. It is understood that, in conjunction with... Figures 1 to 4 The liquid receiver 21 integrates a throttling channel, which is independently set and does not communicate with the built-in channel of the liquid receiver 21. The throttling channel has a throttling inlet that connects to the subcooling outlet of the subcooler 24 and a throttling outlet that connects to the inlet of the evaporator 23. This can realize the pressure and flow regulation of the refrigerant flowing from the condenser 22 to the evaporator 23. At the same time, it helps to improve the integration of the liquid receiver 21 and the third valve 33, reduce external piping, and thus improve the integration of the heat exchange liquid receiver assembly 20 and reduce the space occupied by the heat exchange liquid receiver assembly 20.
[0126] The refrigerant flow path is used for the refrigerant flowing in from the third inlet to exchange heat in sequence through the condenser 22, the liquid receiver 21, the subcooler 24 and the evaporator 23, and also for the refrigerant after heat exchange to flow back to the third outlet through the liquid receiver 21, the subcooler 24 and the condenser 22.
[0127] The heat exchanger can be a plate heat exchanger, which uses plates stacked together. The gaps between adjacent plates form a first inter-plate flow channel and a second inter-plate flow channel that are not interconnected. The first inter-plate flow channel is configured as a refrigerant flow path for refrigerant flow and is connected to the exhaust port 1204 of the compressor 10 through corner holes on the plates. The second inter-plate flow channel is configured as a coolant flow path for coolant flow and is connected to the corresponding functional system. The refrigerant and coolant exchange heat through the plates.
[0128] Specifically, such as Figure 1 To and Figure 4Taking the subcooler 24 located between the liquid receiver 21 and the condenser 22 as an example, the first inlet and the first outlet on the condenser 22 are connected through the first coolant flow path and are used to connect the corresponding functional system, so that the coolant in the coolant flow path of the condenser 22 can exchange heat with the coolant in the first coolant flow path; the second inlet and the second outlet on the evaporator 23 are connected through the second coolant flow path and are used to connect the corresponding functional system, so that the coolant in the coolant flow path of the evaporator 23 can exchange heat with the coolant in the second coolant flow path.
[0129] In normal cooling and heating processes, the heat exchange liquid storage assembly 20 is connected to the compressor 10 through the condenser 22. The third inlet of the condenser 22 is directly connected to the exhaust port 1204 of the compressor 10, so that the refrigerant can directly enter the condenser 22 through the third inlet (exhaust port 1204), liquefy and release heat to the coolant, and complete the heat exchange. In order to avoid refrigerant leakage, a first sealing ring 73 is set between the third inlet and the exhaust port 1204.
[0130] To ensure that the refrigerant that has completed heat absorption flows back to the compressor 10 to re-enter the cycle, the receiver 21 has a through hole connecting the evaporator 23 and the condenser 22. This through hole connects to a portion of the refrigerant flow path formed by the overlapping corner holes on the evaporator 23 and the portion of the refrigerant flow path formed by the overlapping corner holes on the condenser 22. This allows the refrigerant that has completed heat absorption to pass through the evaporator 23, receiver 21, subcooler 24, and condenser 22 in sequence, and enter the compressor 10 through the suction port 1203. Together with the refrigerant flow path in the compressor 10, it completes one cycle.
[0131] To ensure the reliability of heat exchange within the heat exchange and storage assembly 20, in one embodiment, a first heat insulation pad is provided on the outside of the evaporator 23, specifically positioned between the evaporator 23 and the storage tank 21. When the refrigerant undergoes a vaporization reaction within the evaporator 23, it prevents the refrigerant from absorbing heat from the storage tank 21 to a certain extent. When the first heat insulation pad completely encloses the evaporator 23, it also prevents the refrigerant from absorbing heat from the surrounding area of the evaporator 23, such as heat from the storage tank 21 or heat from the external environment. Furthermore, it reduces the heat dissipation of the refrigerant after heat absorption, thereby reducing the impact on the downstream circulation.
[0132] In one embodiment, a second heat insulation pad is provided on the outer periphery of the heat exchange liquid storage assembly 20. The second heat insulation pad wraps the evaporator 23, the liquid storage tank 21, the subcooler 24 and the condenser 22, thereby improving the heat insulation effect of the heat exchange liquid storage assembly 20.
[0133] In addition, since the heat exchange liquid storage assembly 20 is connected to the compressor 10 through the condenser 22, and the refrigerant outlet of the condenser 22 and the compressor 10 is directly connected to the suction port 1203 of the compressor 10, the refrigerant enters the compressor 10 directly through the refrigerant outlet (suction port 1203). In order to avoid refrigerant leakage, a second sealing ring 73 is provided between the refrigerant outlet and the suction port 1203.
[0134] Optionally, the upper part of the receiver 21 is provided with an oil detection pipe 66, which is connected to the inlet of the third valve 33. The oil detection pipe 66 can be connected to external testing equipment to detect the state of the refrigerant. This facilitates the detection of the oil level in the receiver 21. Optionally, the receiver 21 is provided with a third sensor 63, configured to detect the outlet refrigerant temperature and / or pressure of the evaporator 23. Further, the receiver 21 is provided with a fourth sensor 64, configured to detect the inlet refrigerant temperature and / or pressure of the third valve 33. Further, the receiver 21 is provided with a fifth sensor 65, configured to detect the outlet refrigerant temperature and / or pressure of the third valve 33.
[0135] In some embodiments, the water cooling flow path includes a first flow path 201 and a second flow path 202, with the first flow path 201 located in the condenser 22 and the second flow path 202 located in the evaporator 23.
[0136] The present invention also proposes a thermal management system, wherein the vehicle includes the aforementioned thermal management device 100 and / or the aforementioned compressor. The specific structure of the compressor and the thermal management device 100 is as described in the above embodiments. Since the present thermal management system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0137] The present invention also proposes a vehicle, which includes the aforementioned compressor, thermal management device, thermal management system and / or vehicle. The specific structure of the compressor, thermal management device, thermal management system and / or vehicle refers to the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0138] This invention provides a thermal management device 100, which includes a compressor 10, a heat exchange and liquid storage assembly 20, multiple sensors, fixing bolts, multiple valves (which may be electronic expansion valves), a refrigerant charging port, vibration damping pads 72, and a support base 71. The compressor 10 includes a housing 11 and an exhaust distribution component 12. The liquid storage and heat exchange assembly may include an evaporator 23, a condenser 22, a subcooler 24, and a liquid receiver 21.
[0139] The exhaust distribution component 12 is equipped with a first valve 31, a second valve 32, a first sensor 61, a transparent window 122, etc.
[0140] The reservoir 21 is equipped with a third sensor 63, a fourth sensor 64, a fifth sensor 65, a third valve 33, a first observation window 211, a second observation window 212, and an oil detection tube 66, etc.
[0141] The thermal management device 100 includes a refrigerant circuit and a coolant circuit. Both circuits operate in closed loops and exchange heat through heat exchangers (including an evaporator 23, a condenser 22, and a subcooler 24), thereby achieving effective temperature control of the vehicle battery, electric drive system, and passenger compartment. The condenser 22, subcooler 24, receiver 21 (which integrates a desiccant and filter), and evaporator 23 are stacked sequentially along the axis of the compressor 10, away from the compressor 10.
[0142] The condenser 22, subcooler 24, liquid receiver 21 (which integrates desiccant and filter) and evaporator 23 are integrated into a whole by welding or bolting. The refrigerant flows through the internal flow channels of adjacent heat exchangers or liquid receivers 21.
[0143] The compressor 10 and the heat exchange liquid storage assembly 20 are connected as a whole by a sealing ring 73 and bolts. The refrigerant flows and undergoes phase change between the two to heat and cool the externally flowing coolant. Different sub-components of the compressor 10 are connected by sealing rings 73 and bolts. The coolant enters and exits through the inlet and outlet of the evaporator 23 and the condenser 22 to achieve heat exchange between the coolant and the refrigerant.
[0144] A refrigerant flow channel is formed on the side of the heat exchanger liquid storage assembly 20 by welding or bolting. The welded flow channel inlet is connected to the exhaust distribution component 12 by a sealing ring 73 and bolts. A refrigerant flow channel is formed on the side of the heat exchanger liquid storage assembly 20 by welding or bolting. The welded flow channel outlet is connected to the compressor 10 suction flow channel 1042 by a sealing ring 73 and bolts.
[0145] In conjunction with the foregoing, the thermal management device 100 of the present invention has a first operating mode and a second operating mode.
[0146] In the first operating mode: After being compressed by the compressor 10, the high-pressure refrigerant flows out through the first valve 31 (fully open) and the exhaust distribution component 12, and then enters the condenser 22 through the sealing ring 73. In the condenser 22, the refrigerant releases heat into the coolant (which can be antifreeze). After exiting the condenser 22, the refrigerant passes through the internal through-hole of the subcooler 24 and enters the receiver 21. In the receiver 21, the liquid and gaseous refrigerant are separated, and the liquid refrigerant flows into the inlet of the subcooler 24 through the outlet of the receiver 21. In the subcooler 24, the refrigerant and coolant undergo secondary heat exchange, further increasing the subcooling degree of the refrigerant. After exiting the subcooler 24, the refrigerant enters the inlet of the third valve 33 integrated on the receiver 21 from the outlet of the subcooler 24. In the third valve 33, the refrigerant flow rate is regulated and throttled. The refrigerant flowing out of the third valve 33 enters the evaporator 23 through the refrigerant channel integrated on the receiver 21. In the evaporator 23, the refrigerant expands and absorbs heat from the coolant. The refrigerant that has completed heat absorption flows out from the side of the water-cooled evaporator 23 and enters the refrigerant channel on the side of the heat exchanger and receiver 21. The refrigerant enters the suction channel 1042 of the compressor 10 through the sealing ring 73, and is finally drawn into the low-pressure chamber of the compressor 10. The drawn-in low-pressure refrigerant is pressurized by the high-pressure chamber of the compressor 10 and flows out from the exhaust distribution component 12 to complete one cycle. In this mode, the second valve 32 remains closed. The coolant exchanges heat with the evaporator 23 and the condenser 22. If the heat exchanger in the passenger compartment is connected to the coolant in the evaporator 23, it achieves the function of cooling or demisting; if the heat exchanger in the passenger compartment is connected to the coolant in the condenser 22, it achieves the function of heating or defrosting.
[0147] In the second operating mode, when the normal refrigerant circulation cannot meet the system's heating demand, a portion of the refrigerant flows out of the exhaust distribution unit 12 through the first valve 31 (partially open), then through the sealing ring 73 and into the condenser 22. The refrigerant entering the condenser 22 then flows sequentially through the condenser 22, the receiver 21, the subcooler 24, the third valve 33, and the evaporator 23, finally being drawn into the compressor 10 through the suction channel 1042. Simultaneously, another portion of the refrigerant passes through the first valve 31 (partially open) and the second valve 32 (partially open) and also enters the compressor 10's suction channel 1042. Within the compressor 10's suction channel 1042, the two refrigerant paths mix. After mixing, the refrigerant is pressurized again by the compressor 10 and flows out to the exhaust distribution unit 12, completing the heating cycle. The return flow channels through the first valve 31 and the second valve 32 increase the total flow rate of the refrigerant through the compressor 10, increasing the compressor 10's output power and improving the system's heating capacity. The discharge pressure of the compressor 10 can be adjusted by regulating the opening of the first valve 31, which can also increase the output power of the compressor 10 to achieve rapid heating.
