Detailed Implementation

[0037] 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.

[0038] like Figures 1 to 3The thermal management device 100 according to an embodiment of the present invention is applicable to vehicles, and may also be applicable to ships or aircraft. The thermal management device 100 may include a compressor 11, a heat exchanger assembly, and a heating assembly 20. The heat exchanger assembly is connected to the compressor 11, and the compressor 11 can drive the refrigerant to circulate. When the refrigerant passes through the heat exchanger assembly, the heat exchanger assembly can be used to heat and / or cool the heat exchange medium. In other words, the heat exchanger assembly is configured to use a phase change of the refrigerant to heat and / or cool the heat exchange medium. Additionally, the heating assembly 20 is installed on the compressor 11 and is configured to heat the heat exchange medium using electric heating.

[0039] According to the embodiment of the present invention, the thermal management device 100 integrates an electric heating structure and a refrigerant heat exchange structure, which can utilize refrigerant phase change and electric heating to regulate temperature, optimize the temperature regulation effect on the vehicle, and improve the integration of the thermal management device 100.

[0040] The heating component 20 has an electric heating inlet 201 and an electric heating outlet 202, which provides heat to external parts through the circulation of the 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 by the compressor 11 will undergo condensation and heat release and evaporation and heat absorption when passing through the heat exchanger component. The condensation and heat release of the refrigerant can heat the heat exchange medium and heat the vehicle interior space when the heat exchange medium passes through the air conditioning path; the evaporation and heat absorption of the refrigerant can cool the heating medium and cool the vehicle interior space when the heat exchange medium passes through the air conditioning path.

[0041] Optionally, in some embodiments, the heating component 20 may be installed on the side of the compressor 11. In other embodiments, the heating component 20 is powered by a control component located in the compressor 11, which can reduce the length of the thermal management device along the axial direction and improve the space utilization of the thermal management device.

[0042] 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] In some embodiments, the thermal management device 100 further includes a control component for controlling the operation of the compressor 11. The control component is electrically connected to the heating component 20 and supplies power to the heating component 20. The control component can be used to supply power to the heating component 20 and control its operation, which simplifies the structure of the thermal management device 100 and optimizes its performance.

[0044] Of course, using the control components of the compressor 11 to supply power to the heating component 20 is only one embodiment of the present invention and is not a limitation on the scope of protection of the present invention. The compressor 11 and the heating component 20 in the present invention can be configured to be controlled or powered independently, etc.

[0045] like Figure 5 and Figure 6 In some embodiments, the compressor 11 may include a low-pressure housing 111, which has a spaced-apart suction chamber 1106 and an electrical control chamber, with at least a portion of the control component located in the electrical control chamber. This facilitates the integration of the compressor 11 and the control component and provides space for the control component to connect to the compressor 11 and the heating component 20, etc., thus facilitating the control of the thermal management device 100. Furthermore, by placing the control component in the low-pressure housing 111, the low pressure and low temperature of the suction chamber 1106 within the low-pressure housing 111 can be utilized for heat dissipation, effectively improving the operational stability of the control component.

[0046] The electrical control cavity includes a first cavity 1102 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 electrical control cavity, and the electric heating connector 309 is located on the side wall of the first cavity 1102 and is electrically connected to the control board and the heating assembly 20. 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 20, thereby realizing the power supply and power regulation for water heating.

[0047] In addition, the electrical control cavity also includes a second cavity 1103 located on the outer side of the periphery of the low-pressure housing 111. This improves the space utilization of the compressor 11 and facilitates its stable operation. The second cavity 1103 and the first cavity 1102 can be interconnected. This invention provides an electrical control cavity 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. The electrical control cavity contains two sets of high-voltage cables 311 (UVW three-phase lines): one set from the high-voltage connector of the compressor 11's motor stator, and one 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 compressor 11 stator. These two sets of high-voltage cables 311 can be located in the first cavity 1102.

[0048] In addition, a high-voltage connector 307 and a low-voltage connector are installed on the side wall of the electronic control cavity. 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.

[0049] 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.

[0050] 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.

[0051] In some embodiments, the control cavity has a heat dissipation surface near the intake cavity 1106. The control component includes power devices disposed within the control cavity, which are heat exchanged 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.

[0052] like Figure 3 and Figure 4 In some embodiments, the thermal management device 100 has multiple refrigerant channels connecting the compressor 11 and the heat exchanger assembly. The heating assembly 20 is located on one radial side of the compressor 11, and the multiple refrigerant channels are located near the opposite radial side of the compressor 11. Positioning the multiple refrigerant channels to the side of the heating assembly 20 reduces mutual interference between the heating assembly 20 and the refrigerant channels, enabling stable operation of both the heating assembly 20 and the heat exchanger assembly, and improving the stability of the thermal management system.

[0053] like Figure 3In some embodiments, the compressor 11 has an intake chamber 1106 and an exhaust chamber 1107 distributed along an axis. The compressor 11 has an intake side 1104 and an exhaust side 1105 opposite each other along an axis. The heat exchanger assembly includes an evaporator 13 and a condenser 12. The evaporator 13 is arranged on the intake side 1104 of the compressor 11 and communicates with the intake chamber 1106. The condenser 12 is arranged on the exhaust side 1105 of the compressor 11 and communicates with the exhaust chamber 1107. 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 recompressed by the compressor 11. The compressed refrigerant then re-enters a new cycle of cooling 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.

[0054] 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.

[0055] In some embodiments, the heat exchanger assembly further includes a liquid receiver assembly 14, a subcooler 15, a first throttle valve 16 and a second throttle valve 17, and an exhaust chamber 1107, a condenser 12, a liquid receiver assembly 14, a subcooler 15, a first throttle valve 16, an evaporator 13 and an intake chamber 1106 are connected to form a circulation loop, and the exhaust chamber 1107, the second throttle valve 17 and the intake chamber 1106 are connected to form a bypass loop.

[0056] 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.

[0057] Additionally, the thermal management device 100 may have multiple refrigerant channels that connect the exhaust chamber 1107, condenser 12, receiver assembly 14, subcooler 15, first throttle valve 16, evaporator 13 and suction chamber 1106 to guide refrigerant flow. At least a portion of the multiple refrigerant channels may be arranged in a direction parallel to the axis of the compressor 11.

[0058] like Figure 3 The 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.

[0059] 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 setting the fourth flow channel 104 and the fifth flow channel 105, the formation of the refrigerant flow channels can be facilitated. The fourth flow channel can guide the refrigerant from one side of the compressor to the other side, facilitating the refrigerant's evaporation and heat absorption. The cooling capacity generated during this evaporation and heat absorption process can then be used to cool the heat exchange medium, thereby improving the efficiency and effectiveness of cooling the heat exchange medium. Furthermore, by setting 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.

[0060] 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.

[0061] Optionally, the multiple refrigerant flow paths also include a seventh flow path 107, an eighth flow path 108, and a ninth flow path 109. One end of the seventh flow path 107 is connected to the outlet of the evaporator 13, the eighth flow path 108 is connected to the other end of the seventh flow path 107 and the suction chamber 1106, and the eighth flow path 108 extends in a direction perpendicular to the seventh flow path 107. The ninth flow path 109 is connected to the outlet of the second throttle valve 17 and the other end of the seventh flow path 107, and the inlet of the second throttle valve 17 is connected to the exhaust chamber 1107. This facilitates the return of refrigerant through the refrigerant circuit and refrigerant bypass to the compressor's suction chamber via the eighth flow path, simplifying the flow path within the compressor and improving the compressor's operational stability.

[0062] In conjunction with the foregoing, at least one of the first flow channel 101, the second flow channel 102, the third flow channel 103, the fourth flow channel 104, the sixth flow channel 106, the seventh flow channel 107, and the ninth flow channel 109 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.

[0063] In combination with the aforementioned refrigerant integrated module, there are a total of no fewer than nine 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 connected to the fourth... The refrigerant flow channel 104 is vertically arranged 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 connects the outlet of the second throttle valve 17 and the inlet of the eighth flow channel 108.

[0064] 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.

[0065] 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 throttle valve 17 through the exhaust channel 1108, and then enters the suction chamber 1106 of the compressor 11 through the ninth channel 109 and the eighth channel 108. The ninth channel 109 and the eighth channel 108 enable hot gas bypass, increasing the refrigerant flow in the compressor 11, thereby allowing for greater heating power output and increasing the system's heating capacity.

[0066] like Figures 1 to 6 A charging valve is arranged in the suction flow passage of the suction chamber 1106 and / or the exhaust flow passage 1108 of the exhaust chamber 1107 of the compressor 11 for rapid charging of refrigerant into the refrigerant module on the production line. A first charging valve 303 is provided in the suction flow passage of the suction chamber 1106, and a second charging valve 304 is provided in the exhaust flow passage 1108 of the exhaust chamber 1107. The suction flow passage of the suction chamber 1106 can be the aforementioned eighth flow passage 108, and the exhaust flow passage 1108 of the exhaust chamber 1107 can be located within the exhaust chamber 1107 for refrigerant to be discharged from the exhaust chamber 1107. Optionally, the first charging valve 303 and the second charging valve 304 are located on the same side of the compressor 11 along the radial direction. The radial direction can be referred to as the front-rear direction in the accompanying 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 valve, thereby improving charging efficiency and simplifying the charging process. In addition, it also facilitates the production and processing of the thermal management device 100.

[0067] 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.

[0068] Optionally, the compressor 11 includes a low-pressure housing 111 and a high-pressure housing 112, with an intake chamber 1106 located in the low-pressure housing 111 and an exhaust chamber 1107 located in the high-pressure housing 112. A first throttle valve 16 is located in the low-pressure housing 111, and a second throttle valve 17 is located in the high-pressure housing 112. A subcooler 15 can also be located on the exhaust 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 exhaust side 1105 of the compressor 11. The first throttle valve 16 and the second throttle valve 17 can also be located on the side of the compressor 11 opposite to the heating assembly 20. 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.
