DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1 to 3 According to the thermal management device 100 of the embodiment of the present utility model, it includes a protective component 10, and the protective component 10 has a accommodating cavity 101. The accommodating cavity 101 provides an installation space, and a temperature regulating module can be arranged in the accommodating cavity 101, so as to use the protective component 10 to provide protection for the temperature regulating module. The thermal management device 100 also includes a refrigerant component 20, at least a portion of the refrigerant component 20 is arranged in the accommodating cavity 101, and the refrigerant component 20 is configured to regulate the temperature by using the phase change of the refrigerant. In addition, the accommodating cavity 101 is filled with a flame retardant medium, and the flame retardant medium can be used to provide protection for the refrigerant component 20. When problems such as refrigerant leakage occur in the refrigerant component 20, the flame retardant effect of the flame retardant medium can limit the risk of combustion, explosion, etc. of the leaked refrigerant, thereby improving the stability and safety of the thermal management device 100.

[0029] In addition, the thermal management device 100 may further include a water-side assembly 30, which cooperates with the refrigerant assembly 20 for heat exchange. The heat exchange between the water-side assembly 30 and the refrigerant assembly 20 can be used to adjust the temperature of the water-side assembly 30, and the water-side assembly 30 can be used to extract heat or cold to facilitate temperature regulation. In addition, isolating the refrigerant assembly 20 can further improve the safety of the thermal management device 100.

[0030] According to the thermal management device 100 of the embodiment of the present invention, a flame retardant medium can be used for flame retardancy. Even if a refrigerant leak occurs, the flame retardant effect of the flame retardant medium can avoid risks such as refrigerant combustion and explosion, thereby improving the stability and safety of the thermal management device 100.

[0031] In addition, the refrigerant in the present invention can be set to a flammable refrigerant such as R290. The use of these refrigerants can improve the energy efficiency of the refrigerant component 20. However, the flammability of these flammable refrigerants causes certain safety hazards in the refrigerant component 20. Therefore, in the present invention, by setting a flame retardant medium, even if there is a problem of refrigerant leakage, the safety of the thermal management device 100 can be guaranteed under the flame retardant effect of the flame retardant medium.

[0032] In order to achieve flame retardancy of the refrigerant, the flame retardant medium can be set as a solid medium, a liquid medium or a gaseous medium. Preferably, the flame retardant medium is a gaseous medium, wherein the accommodating cavity 101 can be constructed as a closed cavity, and the flame retardant medium is a flame retardant gas. By filling the closed accommodating cavity 101 with flame retardant gas, the refrigerant component 20 can be effectively wrapped with the flame retardant gas. When the refrigerant leaks from the refrigerant component 20, the leaked refrigerant will enter the accommodating cavity 101. The flame retardant gas can prevent the refrigerant from burning or exploding, thereby improving the safety and stability of the refrigerant component 20. Among them, the flame retardant medium can be set to include non-flammable gas; the flame retardant medium can be set to include carbon dioxide, nitrogen and / or inert gas. In addition, the flame retardant medium is set to be a non-combustible gas, for example, the flame retardant medium is set to not contain oxygen.

[0033] like Figures 1 to 3In some embodiments, the protective component 10 includes a cover 11 and an electrical connector 12. The accommodating cavity 101 is provided in the cover 11, and the electrical connector 12 is provided in the cover 11, and the electrical connector 12 is electrically connected to the refrigerant component 20 and / or the water side component 30. The electrical connector 12 can be used to connect the refrigerant component 20 and / or the water side component 30 to electricity, and to pass signals with external components, so as to form a closed chamber in the cover 11, avoid leakage of the combustion medium in the cover 11, and avoid oxygen and other gases in the environment from entering the accommodating cavity 101, which can improve the stability and safety of the thermal management device 100. In addition, by providing the electrical connector 12, it is possible to facilitate the connection between the thermal management device 100 and external components, simplifying the installation and wiring of the thermal management device 100. The electrical connector 12 may include one or more.

[0034] like Figure 4 The electrical connector 12 may include a housing 121 having a mounting opening, a pin 122 extending through the mounting opening, and a sealing connector 123 sealing the mounting opening and connected to the housing 121 and the pin 122, respectively. The pin 122 may be used to electrically connect to electronic components within the thermal management device 100, as well as to electrically connect to electronic components external to the thermal management device 100, thereby facilitating power supply to the thermal management device 100, communication with the thermal management device 100, control of the operation of the thermal management device 100, and / or obtaining information on the operating status of the thermal management device 100. Among them, the cover 11 can be provided with a mounting hole, and the shell 121 of the electrical connector 12 is installed on the cover 11 and fixedly connected to the periphery of the mounting hole, and a sealing structure can be provided between the shell 121 and the periphery of the mounting hole to close the mounting hole. The pin 122 can have an inner end and an outer end. The inner end of the pin 122 can face the inside of the accommodating cavity 101 and be used to connect the electronic components inside the thermal management device 100; the outer end of the pin 122 can face the outside of the accommodating cavity 101 and be used to connect the electronic components outside the thermal management device 100.

[0035] In addition, the electrical connector 12 may include one or at least two pins, such as Figure 4 As shown, the electrical connector 12 includes at least two pins, and a sealing connector is connected between the at least two pins and between the pins and the housing 121. The sealing connector is used to seal the installation port, wherein the sealing connector can be formed by one-piece plastic wrapping, ceramic terminal sintering or glue pouring.

[0036] like Figure 1The thermal management device 100 also includes an integrated control assembly 50, which is electrically connected to the water-side assembly 30 and the refrigerant assembly 20. The integrated control assembly 50 is provided with at least one connector, which is electrically connected to the electrical connector 12. The integrated control assembly 50 can be used to achieve centralized control of the water-side assembly 30 and the refrigerant assembly 20, thereby improving the integration of the thermal management device 100 and facilitating the control of the operation of the water-side assembly 30 and the refrigerant assembly 20. In addition, integrating the terminal terminals of the refrigerant assembly 20 and the water-side assembly 30 into the thermal management device 100 facilitates the electrical connection between the refrigerant assembly 20, the water-side assembly 30, and the electrical connector 12, simplifying the structure of the thermal management device 100.

[0037] like Figures 1 to 3 In some embodiments, the protective assembly 10 includes a housing 11 and a waterway connector 13. The housing 11 includes a receiving chamber 101, and the waterway connector 13 is provided on the housing 11. The waterway connector 13 is connected to the waterway of the waterside assembly 30. The waterway connector 13 enables connection between the waterside assembly 30 and an external waterway structure, so that water after heat exchange with the refrigerant assembly 20 can be sent out of the thermal management device 100, thereby facilitating connection of the thermal management device 100 with other waterway components and utilizing the thermal management device 100 to regulate the temperature of other components. For example, the thermal management system may include an air conditioning pipeline, which can be connected to the waterside assembly 30 in a loop. When the air conditioning pipeline needs to be used to regulate the temperature, the water in the waterside assembly 30 can be controlled to flow to the air conditioning pipeline to deliver cold water treated by the refrigerant assembly 20 to the air conditioning pipeline. After absorbing heat, the air conditioning pipeline flows to the waterside assembly 30 and exchanges heat with the refrigerant assembly 20, thereby achieving a heat exchange cycle.

[0038] In addition, by providing a water channel connector 13, it is possible to ensure effective sealing of the accommodating chamber 101, improve the sealing effect of the accommodating chamber 101, and further ensure the safety of the refrigerant assembly 20. The water channel connector 13 may include one or at least two, and water outlet and return may be achieved by providing two water channel connectors 13. Furthermore, a control valve or other structure may be provided to regulate the water channel, so as to facilitate temperature regulation of multiple components using the thermal management device 100. Of course, the water channel connector 13 may also include more than three, for example, one water outlet connector and multiple return water connectors; or multiple water outlet connectors and multiple return water connectors; or multiple water outlet connectors and one return water connector, etc.

[0039] Optionally, the refrigerant assembly may include an electric compressor 21, a first heat exchanger, a throttling element, and a second heat exchanger connected in a circulation loop. The water-side assembly may include a first heat exchange pipeline and a second heat exchange pipeline. One of the first heat exchange pipeline and the second heat exchange pipeline is connected to a heated load external to the thermal management device, and the other is connected to a cooled load external to the thermal management device. The first heat exchange pipeline exchanges heat with the first heat exchanger, and the second heat exchange pipeline exchanges heat with the second heat exchanger. The waterway connectors may include a first connector and a second connector connected to the first heat exchange pipeline, and a third connector and a fourth connector connected to the second heat exchange pipeline.

[0040] In addition, a hose connection can be set between the water channel connector 13 and the water side component 30 to facilitate the installation and connection of the water side component 30 and the water channel connector 13, thereby improving the assembly efficiency of the thermal management device 100 and avoiding loose connections or affecting the sealing effect due to thermal expansion and contraction.

[0041] like Figures 1 to 3 In some embodiments, the protective assembly 10 includes a housing 11, an electrical connector 12, and a water connector 13. The electrical connector 12 and the water connector 13 can be arranged in the manner described in the aforementioned embodiments. Furthermore, the electrical connector 12 can be positioned higher than the water connector 13 to ensure electrical safety. Furthermore, the electrical connector 12 and the water connector 13 can be positioned on the same side wall or on different side walls of the housing 11. This facilitates the connection between the thermal management device 100 and external components, simplifies the installation of the thermal management device 100, and reduces installation costs.

[0042] like Figure 1 In some embodiments, the protective component 10 includes a cover shell 11, the accommodating cavity 101 is provided in the cover shell 11, and the refrigerant component 20 is separated from the wall of the cover shell 11 so that the refrigerant component 20 can be wrapped with the flame retardant medium filled in the cover shell 11 to achieve effective protection of the refrigerant component 20.

[0043] In addition, the thermal management device 100 further includes a support assembly 40, which is respectively connected to the refrigerant assembly 20 and the protection assembly 10. The support assembly 40 can be used to support and install the refrigerant assembly 20, thereby improving the stability of the thermal management device 100.

[0044] like Figures 1 to 3In some embodiments, the thermal management device 100 further includes a detector 14, which is configured to detect the refrigerant concentration, the temperature of the flame retardant medium, and / or the pressure of the flame retardant medium in the accommodating chamber 101. For example, the detector 14 can be configured to detect the refrigerant concentration in the accommodating chamber 101. Since a flame retardant medium is provided in the accommodating chamber 101, when a refrigerant leak occurs in the refrigerant assembly 20, the refrigerant will leak into the accommodating chamber 101. This ensures that when a refrigerant leak occurs, the detector 14 can quickly detect it, thereby avoiding the problem of undetectable refrigerant leakage due to the refrigerant being blown away, and improving the detection accuracy of refrigerant leakage. In addition, the working condition of the thermal management device 100 can be obtained by detecting the temperature, pressure, etc. of the flame retardant medium, so as to improve the stability and safety of the thermal management device 100.

[0045] Optionally, the detector 14 may include a refrigerant detection element, and the refrigerant detection element may include at least two sensors, which may be used for detection, and multiple sensors may simultaneously detect the refrigerant concentration at different positions in the accommodating cavity 101. Take the example of the refrigerant detection element including two sensors. For example, when the refrigerant concentrations detected by the two sensors are normal, it can be determined that no refrigerant leakage has occurred. For another example, when one of the sensors detects that the refrigerant concentration is normal, and the other sensor detects that the refrigerant concentration is too high; or the refrigerant concentrations detected by the sensors are all too high, it is considered that a refrigerant leakage may have occurred, and the accuracy of the detection results can be improved, so as to promptly detect the problem of refrigerant leakage and improve the stability of the operation of the thermal management device 100.

[0046] The present invention further provides a thermal management system comprising: the aforementioned thermal management device 100. Furthermore, the thermal management system may also include air conditioning piping, engine cooling piping, battery cooling piping, and other piping. By connecting these piping to the water pipe connector 13, the refrigerant assembly 20 is utilized for temperature regulation, resulting in a stable and highly secure structure.

[0047] The present invention further provides a vehicle, comprising: the aforementioned thermal management device 100; or the aforementioned thermal management system.

[0048] The utility model discloses a thermal management device 100 , a thermal management system and a vehicle, wherein the thermal management device 100 may include at least two components of a water side component 30 , a refrigerant component 20 , a support component 40 , a protection component 10 and an integrated control component 50 .

[0049] Among them, the protection component 10 includes a cover 11, a detector 14, a flame retardant medium, a water connector 13 and an electrical connector 12. The protection component 10 has functions such as flame retardancy, detection, and protection. The flame retardant function can be achieved by non-flammable gas, the flame retardant medium can be a non-flammable gas, and the flame retardant medium can be carbon dioxide, nitrogen or an inert gas. The protection component 10 includes a cover 11, and the cover 11 can integrally wrap the refrigerant component 20 or the entire integrated module. The inside of the cover 11 is filled with a flame retardant medium to prevent the risk of explosion after leakage occurs. The refrigerant component 20 can be configured to be entirely wrapped in the cover 11. Among them, one side of the cover 11 can be directly or indirectly connected to the installation angle of the compressor 21 in the refrigerant component 20, and the other side of the cover 11 can be connected to the support component 40. In addition, the cover 11 can be connected to a support frame, and the support frame is used as a base to fix the thermal management device 100 to the vehicle body mounting frame or other fixed position.

[0050] The detector 14 may include one or more sensors, for example, a detector 14 configured to detect one or more of temperature, pressure, and refrigerant concentration. Through the protective assembly 10, when a refrigerant leak occurs, the refrigerant leaks into the flame-retardant medium, effectively preventing the risk of explosion caused by contact between the refrigerant and oxygen. This ensures ultimate safety while maintaining the compactness of the thermal management system.

[0051] An electrical connector 12 and a water connector 13 are sealed and installed on the cover 11. The electrical connector 12 is used to connect the internal electrical components to the external power supply and collection device. The water connector 13 is used to transport the internal coolant through the cover 11 to other components of the system. A two-way sealing structure is set between the electrical connector 12, the water connector 13, etc. and the cover 11. The two-way sealing structure is used to achieve airtight isolation between the internal cavity of the cover 11 and the external environment. The two-way sealing structure can adopt an integrated casting, injection molding, sintering and other processes. The electrical connector 12 mainly includes three parts: a pin 122, a shell 121, and a sealing connector 123. The sealing connector 123 has the effect of sealing and insulating at the same time, ensuring airtightness while ensuring the electrical safety of the terminal.

[0052] like Figure 5 The water side component 30 may include two or more components including a kettle 31, a flow channel plate, a water valve 32, a water pump 33, a water temperature sensor 34, a temperature and pressure sensor, a heat exchanger, and the like.

[0053] Optionally, in the water side assembly 30, the kettle 31 is located at the top, the flow channel plate is located at the bottom of the kettle 31, and is fixed or sealed relative to the bottom plate of the kettle 31. The kettle 31 contains one or more cavities, and a liquid level sensor for liquid level monitoring can be optionally added. The water valve 32 and the water pump 33 are relatively fixed or sealed relative to the flow channel plate, and the water valve 32 and the water pump 33 can be located simultaneously or separately on the other four surfaces of the kettle 31 except the upper surface and the bottom surface. The water side interface of the heat exchanger is relatively fixed or sealed relative to the flow channel plate to ensure that the water side flow channel in the heat exchanger can be connected to the flow channel of the water side assembly 30. The kettle 31, the flow channel plate, the water valve 32, the water pump 33, the heat exchanger and the remaining thermal management components of the vehicle together form the entire coolant circuit. Sensors are arranged in some of the flow channels of the loop to monitor the temperature or pressure of the fluid in this part of the flow channel.

[0054] Among them, the kettle 31 serves as a device for storing and replenishing coolant, while also taking into account the gas-liquid separation function of the return liquid. When the water side circuit is short of water, the coolant can be replenished to the inlet of the water pump 33 in time. The water valve 32 serves as a flow distribution component. It has an interface for connecting to the flow channel plate. It can realize opening and closing or proportional adjustment in different modes to connect different interfaces to realize different fluid paths in each mode. There is at least one water pump 33, for example, including a heating water pump 33 for connecting to the heating circuit, a battery water pump 33 for the battery circuit, or an electric drive water pump 33 for connecting to the electric drive circuit. The water pump 33 serves as a power drive device for the water side flow channel, responsible for providing power to the fluid in the flow channel and driving the fluid to circulate in the flow channel at a certain flow rate. The flow channel plate has flow channels and interfaces for connecting the water valve 32, water pump 33 and various temperature control components of the vehicle outside the integrated module to form a circulation flow path. The heat exchanger can realize heat exchange between the coolant and the refrigerant on the refrigerant side to control the temperature of the high and low temperature fluids in the water side flow path, so as to achieve efficient energy comprehensive utilization and improve system performance. The sensor includes at least one, which is installed at the inlet or outlet flow channel of the heat exchanger so as to accurately detect the temperature of the flow channel and thus switch and control the corresponding mode.

[0055] like Figure 6 The refrigerant assembly 20 includes a compressor 21, a refrigerant plate 22, a valve device 25, a temperature sensor 24, a pressure sensor, a liquid reservoir 26 or two or more components of a gas separator and various heat exchangers.

[0056] In the refrigerant assembly 20, the compressor 21 is used as the base, and the liquid storage device, heat exchange assembly 23, refrigerant plate 22, refrigerant valve, and sensor are all directly or indirectly fixed relative to and sealedly connected to the compressor 21. Flow channels are also provided inside the refrigerant plate 22 and the heat exchange assembly 23 to jointly form an internal flow channel that is not connected to the outside. The heat exchange assembly 23 includes a plurality of heat exchangers with different functions, such as a cooler Chiller, a heater WCC, a subcooler SC, etc. Sensors are arranged in the upper part of the flow channel of the refrigerant plate 22 to monitor the temperature or pressure of the refrigerant in the required flow channel. The refrigerant plate 22 can be stacked with the flow channel plate, and the heat exchange assembly 23 includes a first heat exchanger and a second heat exchanger arranged on opposite sides of the refrigerant plate 22. The first heat exchanger and the second heat exchanger can be stacked on the lower surface of the refrigerant plate 22. The accumulator 26 may be disposed below the refrigerant plate 22 and between the refrigerant plate 22 and the compressor 21, with the first heat exchanger and the second heat exchanger disposed on opposite sides of the accumulator 26. The lower end of the accumulator 26 may be configured to be shaped to fit the compressor 21.

[0057] The electric compressor 21 is used to drive the refrigerant circulation flow. The refrigerant flow rate in the refrigerant-side system can be adjusted by adjusting the speed. The valve device 25 includes at least one or more of a solenoid valve, an electronic expansion valve, and a one-way valve. The solenoid valve is responsible for opening and closing the flow channel to coordinate the switching of the flow path between different modes. The electronic expansion valve is responsible for throttling the fluid flow and pressure in the flow channel to achieve the temperature requirements in different modes. The one-way valve acts as a control valve for the direction of fluid flow, allowing only one-way flow to prevent backflow in specific modes and ensure normal operation of the mode. The sensors in the refrigerant assembly 20 include at least one or more of a temperature sensor 24, a pressure sensor, or a temperature-pressure integrated sensor. They are selectively installed at the heat exchanger outlet, the liquid reservoir 26, or the gas separator inlet to detect the pressure and temperature of the fluid at the corresponding location. The heat exchanger can simultaneously achieve energy exchange between the refrigerant and the coolant or between the refrigerant and the refrigerant. The liquid reservoir 26 includes a liquid storage chamber, a liquid separation chamber, a liquid return pipe, a filter, and a desiccant, which are used to store excess refrigerant liquid that does not participate in the system circulation to ensure normal operation of the system. The gas-liquid separator includes an inlet, a return air pipe, a gas-liquid separation chamber, and an installation and fixing component, which separates the refrigerant before it enters the compressor 21 to separate the gas and liquid, thereby preventing the compressor 21 from sucking liquid and causing reliability risks such as liquid hammer.

[0058] The support assembly 40 includes a support frame, a damping pad, and other components. The support frame can be connected to the compressor 21 and the housing 11 to provide support for the compressor 21. The damping pad can cooperate with the support frame and the compressor 21 to provide vibration damping for the compressor 21, thereby reducing vibration transmitted from the compressor 21 to the housing 11 and improving the stability of the thermal management device 100.
