Detailed Implementation

[0033] 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.

[0034] like Figures 1 to 4 The thermal management device 100 according to an embodiment of the present invention is suitable for vehicles, and may also be applicable to ships or aircraft. The thermal management device 100 may include a compressor 11, an evaporator 13, and a condenser 12. The compressor 11 has an intake chamber 1106 and an exhaust chamber 1107 distributed along an axis, wherein the axis of the compressor 11 is distributed along the axis of the evaporator 13. Figure 2Extending horizontally, the evaporator 13 is arranged on the outer side of the suction chamber 1106 of the compressor 11 along the axis and connected to the suction chamber 1106. The condenser 12 is arranged on the outer side of the discharge chamber 1107 of the compressor 11 along the axis and connected to the discharge chamber 1107. The evaporator 13 is configured to use refrigerant phase change to refrigerate the heat exchange medium and / or the condenser 12 is configured to use refrigerant phase change to heat the heat exchange medium. The compressor 11 is located between the condenser 12 and the evaporator 13, and the compressor 11, condenser 12 and evaporator 13 are connected to form a refrigerant circulation loop. After being compressed by the compressor 11, the refrigerant flows into the condenser 12 for heat exchange. After heat exchange, the refrigerant flows out of the condenser 12 and flows into the evaporator 13 for a second heat exchange. After the second heat exchange, the refrigerant flows back into the compressor 11 and is compressed again by the compressor 11. The compressed refrigerant then re-enters a new cycle of refrigeration and heating. Compared to placing the condenser 12 and evaporator 13 on the same side of the compressor 11, placing the condenser 12 and evaporator 13 on opposite sides of the compressor 11 simplifies the assembly structure of the thermal management device 100, facilitates the individual installation and disassembly of the condenser 12 and evaporator 13, reduces the size of the condenser 12 and evaporator 13, and improves the integration of the thermal management device 100. Since the condenser 12 and evaporator 13 have different operating states and environments, separating the condenser 12 and evaporator 13 avoids mutual interference between the operating environments of the condenser 12 and evaporator 13, such as temperature factors, thereby improving the operational stability of the thermal management device 100.

[0035] Additionally, the thermal management device 100 may also include at least one charging valve, which connects to the suction chamber 1106 and / or the discharge chamber 1107, and is used to inject refrigerant into the compressor 11. Refrigerant can be charged into the compressor 11 through the charging valve.

[0036] The thermal management device 100 according to an embodiment of the present invention adopts a modular and miniaturized design, which is beneficial to reducing the amount of refrigerant used and facilitating the charging of refrigerant.

[0037] The evaporator 13 may be provided with a first heat exchange inlet 1301 and a first heat exchange outlet 1302, and the condenser 12 may be provided with a second heat exchange inlet 1201 and a second heat exchange outlet 1202. Through liquid circulation, the evaporator 13 can provide low-temperature liquid to external parts to achieve refrigeration; the condenser 12 can provide high-temperature liquid to external parts to achieve heating.

[0038] like Figure 1 and Figure 2In some embodiments, at least one charging valve includes a first charging valve 303 and a second charging valve 304. The first charging valve 303 is connected to the intake flow channel of the intake chamber 1106, and the second charging valve 304 is connected to the exhaust flow channel 1108 of the exhaust chamber 1107. By providing the first charging valve 303 and the second charging valve 304, the charging efficiency of the refrigerant can be improved, thereby increasing the production efficiency of the thermal management device 100.

[0039] The first charging valve 303 and the second charging valve 304 are located on the same radial side of the compressor 11. Radial direction can be referenced to the front-rear direction in the attached drawings. By placing the first charging valve 303 and the second charging valve 304 on the same side, it is convenient to charge refrigerant into the compressor 11 through the charging valves, improving charging efficiency and simplifying the charging process. Additionally, it facilitates the manufacturing and processing of the thermal management device 100. Optionally, as... Figure 5 The intake air passage of the intake chamber 1106 can be an eighth flow passage 108. The eighth flow passage 108 penetrates the low-pressure housing 111. One end of the eighth flow passage 108 is connected to the intake chamber 1106, and the other end of the eighth flow passage 108 is provided with a first filling valve 303 and is closed by the first filling valve 303.

[0040] like Figure 7 As shown, the high-pressure housing 112 may be provided with an exhaust channel 1108, wherein the high-pressure housing 112 may be provided with a mounting hole that penetrates the outer side of the high-pressure housing 112 and the inner circumferential surface of the exhaust channel 1108, wherein one end of the mounting hole is connected to the exhaust channel, and the other end is provided with a second filling valve 304 and is closed by the second filling valve 304.

[0041] Additionally, the thermal management device 100 may include a heating assembly mounted on the compressor 11, configured to heat the heat exchange medium using electric heating. Optionally, the heating assembly is located on one radial side of the compressor 11, and at least one charging valve is located near the opposite radial side of the compressor 11.

[0042] Optionally, the heating assembly has an electric heating inlet and an electric heating outlet, supplying heat to external parts through the circulation of a heat exchange medium. The heat exchange medium can be introduced into the vehicle's heat exchange channels, such as the battery heat exchange path, engine heat exchange path, electronic control heat exchange path, outdoor heat exchanger path, and air conditioning path. The heat exchange medium can be water or other media. Taking the air conditioning path as an example, the refrigerant output from the compressor 11 undergoes condensation and heat release, as well as evaporation and heat absorption, when passing through the heat exchanger assembly. The condensation and heat release of the refrigerant heats the heat exchange medium and, when the heat exchange medium passes through the air conditioning path, heats the vehicle interior; the evaporation and heat absorption of the refrigerant cools the heating medium and, when the heat exchange medium passes through the air conditioning path, cools the vehicle interior. Optionally, the heating assembly can be installed on the side of the compressor 11, and the heating assembly is powered by a control component located within the compressor 11. In addition, in a vehicle equipped with the thermal management device 100, a reversing valve assembly can be installed to switch the flow direction of the heat exchange medium for refrigerant cooling, refrigerant heating and electric heating, so as to control the heat exchange medium for refrigerant cooling, refrigerant heating and electric heating to flow to different channels.

[0043] like Figure 4 In some embodiments, the thermal management device 100 has a plurality of refrigerant channels connecting the compressor 11, the condenser 12 and the evaporator 13, and the charging valve and the plurality of refrigerant channels are located on one side of the compressor 11 in the radial direction.

[0044] In addition, a pressure relief valve 310 can be installed in the exhaust chamber 1107 of the compressor 11 to protect the internal cavity of the compressor 11 from structural damage due to excessive system pressure at any time.

[0045] In some embodiments, the thermal management device 100 further includes a liquid receiver assembly 14, a subcooler 15, and a first throttle valve 16, with the exhaust chamber 1107, condenser 12, liquid receiver assembly 14, subcooler 15, first throttle valve 16, evaporator 13, and suction chamber 1106 connected in a loop to facilitate heat transfer via refrigerant phase change.

[0046] The thermal management device 100 has multiple refrigerant channels, which connect the exhaust chamber 1107, condenser 12, receiver assembly 14, subcooler 15, first throttle valve 16, evaporator 13 and suction chamber 1106 to guide the flow of refrigerant. At least a portion of the multiple refrigerant channels may be arranged in a direction parallel to the axis of compressor 11.

[0047] like Figure 4The system includes multiple refrigerant flow channels, including a first flow channel 101, a second flow channel 102, and a third flow channel 103. The first flow channel 101 connects the exhaust chamber 1107 and the inlet of the condenser 12. The second flow channel 102 connects the outlet of the condenser 12 and the inlet of the receiver assembly 14. The third flow channel 103 connects the outlet of the receiver assembly 14 and the inlet of the subcooler 15. The refrigerant can be discharged from the compressor along the first, second, and third flow channels, flowing to one side of the compressor, and after passing through the condenser, receiver assembly, and subcooler, flowing to the other side of the compressor. The condensation and heat absorption process of the refrigerant takes place on one side of the compressor, which can improve the operating stability and energy efficiency of the compressor.

[0048] Optionally, the multiple refrigerant flow channels also include a fourth flow channel 104 and a fifth flow channel 105. The fourth flow channel 104 passes through the condenser 12 and the compressor 11, with one end connected to the outlet of the condenser 15. The fifth flow channel 105 connects the other end of the fourth flow channel 104 to the inlet of the first throttling valve 16, and extends in a direction perpendicular to the fourth flow channel 104. By providing the fourth and fifth flow channels, the refrigerant flow channel design can be facilitated. The fourth flow channel can guide the refrigerant from one side of the compressor to the other side, facilitating evaporation and heat absorption. The cooling capacity generated during this evaporation process can then be used to cool the heat exchange medium, improving the efficiency and effectiveness of cooling the heat exchange medium. Furthermore, by providing the fifth flow channel, the refrigerant passing through the fourth flow channel can be guided towards the inlet of the evaporator, simplifying the flow channel structure of the thermal management device.

[0049] Optionally, the multiple refrigerant flow channels also include a sixth flow channel 106, which connects the outlet of the first throttling valve 16 and the inlet of the evaporator 13. The sixth flow channel can be used to guide the refrigerant passing through the first throttling valve to the evaporator for evaporation and heat absorption, which can simplify the connection structure between the compressor and the evaporator and facilitate a stable connection between the compressor and the evaporator through docking.

[0050] In some embodiments, at least one of the first flow channel 101, the second flow channel 102, the third flow channel 103, the fourth flow channel 104, and the sixth flow channel 106 extends in a direction parallel to the axis of the compressor 11. This simplifies the structure of the thermal management device 100, facilitates its molding, and enables the refrigerant to flow smoothly, improving the stability of the refrigerant flow process and enhancing the heat exchange performance of the heat exchanger assembly.

[0051] In some embodiments, the thermal management device 100 further includes a second throttle valve 17, and the exhaust chamber 1107, the second throttle valve 17, and the suction chamber 1106 are connected to form a bypass circuit. Optionally, a first throttle valve 16 (e.g., an electronic expansion valve) is installed on the low-pressure housing 111 of the compressor 11, and a second throttle valve 17 (e.g., an electronic expansion valve) is installed on the high-pressure housing 112. The refrigerant flow rate and cooling / heating power of the system are adjusted by controlling the opening degree of the first throttle valve 16; the hot gas bypass function is adjusted by controlling the opening degree of the second throttle valve 17, and rapid heating can be achieved outside the operating temperature range of the heat pump through the hot gas bypass function.

[0052] The thermal management device 100 has multiple refrigerant channels, including a ninth channel 109, a tenth channel 1010, and an eleventh channel 1011. The ninth channel 109 is connected to the exhaust chamber 1107 and the inlet of the second throttle valve 17. One end of the tenth channel 1010 is connected to the outlet of the second throttle valve 17. One end of the eleventh channel 1011 is connected to the other end of the tenth channel 1010. The other end of the eleventh channel 1011 is connected to the intake chamber 1106. The tenth channel 1010 extends in a direction perpendicular to the eleventh channel 1011.

[0053] Optionally, the multiple refrigerant channels also include a seventh channel 107 and an eighth channel 108. One end of the seventh channel 107 is connected to the outlet of the evaporator 13, and the other end of the seventh channel 107 is connected to one end of the eighth channel 108 and the other end of the eleventh channel 1011. The eighth channel 108 is connected to the other end of the seventh channel 107 and the suction chamber 1106. The eighth channel 108 extends in a direction perpendicular to the seventh channel 107.

[0054] Furthermore, at least one of the seventh flow channel 107, the ninth flow channel 109, and the eleventh flow channel 1011 extends in a direction parallel to the axis of the compressor 11. This simplifies the structure of the thermal management device 100, facilitates its molding, and enables the refrigerant to flow smoothly, improving the stability of the refrigerant flow process and enhancing the heat exchange performance of the heat exchanger assembly.

[0055] In combination with the aforementioned refrigerant integrated module, there are a total of no fewer than 11 refrigerant flow channels. The first flow channel 101 flows out from the exhaust chamber 1107 of the compressor 11 and into the condenser 12; the second flow channel 102 flows out from the condenser 12 and into the receiver assembly 14; the third flow channel 103 flows out from the receiver assembly 14 and into the subcooler 15; the fourth flow channel 104 flows out from the subcooler 15, passes through the condenser 12, the high-pressure housing 112 of the compressor 11, and the low-pressure housing 111 of the compressor 11, and reaches the inlet of the first throttle valve 16; the fifth flow channel 105 is a section perpendicular to the fourth flow channel 104. The refrigerant flow channels are used to change the direction of refrigerant flow; the sixth flow channel 106 flows out from the outlet of the first throttle valve 16 and into the inlet of the evaporator 13; the seventh flow channel 107 flows out from the evaporator 13 and into the low-pressure housing 111 of the compressor 11; the eighth flow channel 108 is perpendicular to the seventh flow channel 107 and introduces the refrigerant from the evaporator 13 into the suction chamber 1106 of the compressor 11; the ninth flow channel 109, the tenth flow channel 1010 and the eleventh flow channel 1011 connect the outlet of the second throttle valve 17 and the inlet of the eighth flow channel 108.

[0056] In both cooling and heating modes, the refrigerant, pressurized by the compressor 11, flows out of the exhaust chamber 1107, passes through the first flow channel 101, and enters the condenser 12. In the condenser 12, the refrigerant dissipates heat. The dissipated refrigerant then flows through the second flow channel 102 into the liquid receiver assembly 14, where the gaseous and liquid refrigerant are separated. The liquid refrigerant then flows through the third flow channel 103 into the subcooler 15, where it further dissipates heat and reduces its enthalpy. The refrigerant exiting the subcooler 15 flows through the fourth flow channel 104 and the fifth flow channel 105 into the inlet of the first throttling valve 16, where it is throttled. The throttling amount is adjusted by the opening of the first throttling valve 16. The throttled refrigerant then flows through the sixth flow channel 106 into the evaporator 13, where it absorbs heat from the water side to cool the water. After evaporation, the refrigerant enters the suction chamber 1106 of the compressor 11 through the seventh flow channel 107 and the eighth flow channel 108, completing a full refrigerant cooling and heating cycle. During the cooling and heating cycle, the second expansion valve 17 is closed throughout, and no refrigerant flows.

[0057] When the ambient temperature is below the temperature range within which the heat pump can operate normally, the refrigerant in the evaporator 13 cannot evaporate effectively, limiting the refrigerant flow and heating capacity of the system. At this time, the refrigerant flows out of the exhaust chamber 1107 of the compressor 11, enters the inlet of the second throttling valve 17 through the ninth flow channel 109, and then flows through the tenth flow channel 1010, the eleventh flow channel 1011, and the eighth flow channel 108 into the suction chamber 1106 of the compressor 11. The hot gas bypass function is achieved through the eighth flow channel 108, the ninth flow channel 109, the tenth flow channel 1010, and the eleventh flow channel 1011, increasing the refrigerant flow within the compressor 11, thereby enabling the output of greater heating power and increasing the system's heating capacity.

[0058] like Figure 3 In some embodiments, the compressor 11 includes a low-pressure housing 111 and a high-pressure housing 112. A suction chamber 1106 is located in the low-pressure housing 111, and a discharge chamber 1107 is located in the high-pressure housing 112. The thermal management device 100 further includes a first throttling valve 16 and a second throttling valve 17. The first throttling valve 16 controls the refrigerant flow rate, and the second throttling valve 17 controls the bypass refrigerant flow path. The first throttling valve 16 is located in the low-pressure housing 111, and the second throttling valve 17 is located in the high-pressure housing 112. A subcooler 15 can also be located on the discharge side 1105 of the compressor 11. The subcooler 15 and the condenser 12 can also be welded together to form a single unit. A liquid receiver assembly 14 can also be located on the discharge side 1105 of the compressor 11. The first throttling valve 16 and the second throttling valve 17 can also be located on the side of the compressor 11 away from the heating assembly. The above-mentioned configuration can improve the integration of the thermal management device 100, thereby facilitating its high integration and miniaturization. It also enables the thermal management device 100 to be configured as a single module, which facilitates its production and assembly, and reduces its production and maintenance costs.

[0059] In addition, the compressor 11 is designed with a bearing housing 305, in which a sliding bearing is installed, which supports the end of the motor shaft of the compressor 11.

[0060] In addition, the low-pressure housing 111 and the high-pressure housing 112 are each designed with 3 connecting brackets. The brackets are connected to the vibration isolation pads by bolts, and the vibration isolation pads are connected to the vehicle body to isolate the vibration of the compressor 11.

[0061] In some embodiments, a first sensor 301 is arranged on the side of the exhaust passage 1108 of the exhaust chamber 1107 to detect the exhaust pressure and / or exhaust temperature of the compressor 11; and / or, a second sensor 302 is arranged at the end of the intake passage of the intake chamber 1106 to detect the intake pressure and / or intake temperature of the compressor 11. This allows for timely monitoring of the compressor 11's operating status, facilitating stable operation control. Furthermore, based on the operating status of the first sensor 301 and the second sensor 302, the opening degrees of the first throttle valve 16 and the second throttle valve 17 can be controlled to optimize the compressor 11's performance. The sensors can be pressure sensors, temperature sensors, etc., and optionally, both pressure and temperature sensors can be integrated.

[0062] This invention discloses a thermal management device 100. The thermal management device 100 mainly includes: a compressor 11 (whose main components include: a motor stator, a motor rotor, a low-pressure housing 111, a high-pressure housing 112, a bearing bracket 305, a control box, a high-pressure connector 307, and a low-pressure connector, etc.), a condenser 12, an evaporator 13, a subcooler 15, a first throttling valve 16, a second throttling valve 17, a first charging valve 303, a second charging valve 304, a pressure relief valve 310, and heating components, etc. The control box houses components such as a PCB board, capacitors, inductors, and IGBT modules.

[0063] The thermal management device 100 can form an independent and complete refrigerant circulation system. It provides power to the compressor 11 through high voltage electricity and controls the compressor 11 and electronic expansion valve through a low-pressure system. The module assembly realizes the functions of cooling and heating. The thermal management device 100 realizes heat exchange with the external system through the evaporator 13 and the condenser 12.

[0064] In some embodiments, the compressor 11 may include a low-pressure housing 111, which has a spaced-apart suction chamber 1106 and a mounting chamber 1102. At least a portion of the control assembly is disposed in the mounting chamber 1102. This facilitates the integration of the compressor 11 and the control assembly and provides space for the control assembly to connect to the compressor 11 and heating components, thereby facilitating the control of the thermal management device 100. Furthermore, by placing the control assembly in the low-pressure housing 111, the low pressure and low temperature of the suction chamber 1106 within the housing can be utilized for heat dissipation, effectively improving the operational stability of the control assembly.

[0065] The mounting cavity 1102 includes a first cavity located on the outer side of the end of the low-pressure housing 111. The control assembly includes a control board and an electric heating connector 309 electrically connected to the control board. The control board is located in the mounting cavity 1102, and the electric heating connector 309 is located on the side wall of the first cavity and electrically connected to the control board and the heating assembly. A vertically arranged electric heating connector 309 is provided on the side of the compressor 11 for connecting the control board and the heating assembly, thereby enabling power supply and power regulation for water heating.

[0066] Additionally, the mounting cavity 1102 also includes a second cavity located on the outer side of the peripheral wall of the low-pressure housing 111. This improves the space utilization of the compressor 11 and facilitates stable operation of the compressor 11. The second cavity and the first cavity can be interconnected. This invention provides a mounting cavity 1102 in the low-pressure housing 111 and houses at least a portion of the control components therein. The control components may include a control board, capacitors, inductors, IGBT modules, and high-voltage cables 311, etc. Figure 6 The mounting cavity 1102 contains two sets of high-voltage cables 311 (UVW three-phase lines): one set from the high-voltage connector of the motor stator of the compressor 11, and the other set from the control board. The two sets of high-voltage cables 311 intersect on the side of the low-pressure housing 111 of the compressor 11 and are connected by welding. This enables the control board to supply power and control the stator of the compressor 11. These two sets of high-voltage cables 311 can be located in the first cavity.

[0067] In addition, a high-voltage connector 307 and a low-voltage connector are installed on the side wall of the mounting cavity 1102. The high-voltage connector 307 connects to the high-voltage wiring harness of the vehicle, providing high-voltage electricity to the compressor 11 and realizing the interlocking function of the high-voltage system. The low-voltage connector connects to the low-voltage wiring harness of the vehicle, providing low-voltage control signals to the compressor 11. The vehicle controls the compressor 11 and receives feedback signals from the compressor 11 through the low-voltage connector.

[0068] The control board receives control signals from the low-voltage connector and converts the DC power from the high-voltage connector 307 into AC power with adjustable frequency and voltage, which generates a rotating magnetic field through the stator coils. The motor rotor rotates under the influence of this rotating magnetic field.

[0069] The moving scroll 306 of the compressor 11 and the motor rotor are connected together through the motor main shaft. The moving scroll 306 generates a spiral translation under the drive of the motor rotor.

[0070] In some embodiments, the mounting cavity 1102 has a heat dissipation surface near the intake cavity 1106. The control component includes power devices disposed within the mounting cavity 1102. The power devices are heat-exchange matched with the heat dissipation surface for heat exchange between the power devices and the refrigerant within the intake cavity 1106. A heat dissipation surface is designed on the low-pressure housing 111. The heat generated by the power module (IGBT module) on the control board is efficiently conducted through the heat dissipation surface. The heat conducted to the low-pressure housing 111 is released into the refrigerant through convection heat exchange between the low-pressure housing 111 and the refrigerant.
