Description

Technical Field

[0001] This invention relates to a thermal management system, and more particularly to an onboard agent-side decoupling system. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this invention and does not constitute prior art.

[0003] In vehicle-mounted thermal management systems, the main functions generally consist of refrigerant compression, cooling / cooling, and heating / cooling. In some scenarios, a water-cooled LCC (liquid cooler) acts as the condenser, and a water-cooled chiller acts as the evaporator. By intelligently controlling the circulation paths of the refrigerant and coolant, efficient cooling, heating, and energy recovery are achieved, making it particularly suitable for electric and hybrid vehicles. However, because the water cooler and chiller require simultaneous connection to both refrigerant and water lines, the intersection of these two different lines leads to a complex system structure, making low-cost and rapid installation difficult. Furthermore, to achieve rapid temperature regulation in the passenger compartment, refrigerant may be introduced into the passenger compartment, which carries lower safety risks, especially when using R290 refrigerant. Excessively long refrigerant pipes increase the risk of leakage, affecting thermal management efficiency and posing safety hazards.

[0058] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0059] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated in advance. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0060] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0061] Please see Figure 1 This embodiment provides a vehicle-mounted agent-side decoupling system, which includes:

[0062] Water cooler 22, water cooler 22 has a first condensate passage and a first water cooling passage;

[0063] Refrigerator 24, refrigerator 24 has a second condensate passage and a second water cooling passage;

[0064] At least two functional components with heat exchange capabilities;

[0065] The agent-side integrated mechanism 2 includes a compressor 21 and an expansion valve 22; the compressor 21, the first condensate circuit of the water cooler 22, the expansion valve 23, and the second condensate circuit of the refrigerator 24 are connected in series.

[0066] The first water-cooling passage is connected to at least one functional component with heat exchange function via a water channel;

[0067] The second water-cooling passage is connected to at least one functional component with heat exchange function via a water path.

[0068] Specifically, in the above structure, the corresponding water passage can be mixed or heat exchanged through the water-side valve island 1.

[0069] In the above structure, the water-side valve island 1 is mainly used to collect and exchange heat from water flows of different temperatures introduced from the agent-side integrated mechanism 2, passenger cabin mechanism 3, and fan heat exchange mechanism 4. It can mix cold and hot water flows according to actual needs to achieve temperature control. The water-side valve island 1 can switch between different flow channels through electronic control. In this embodiment, the water-side valve island 1 is a conventional multi-way valve body, such as a disc valve.

[0070] In actual operation, compressor 21 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant, which then enters the downstream water cooler 22. The high-temperature, high-pressure refrigerant heats the water flow in water cooler 22 and flows to expansion valve 23. After expansion and pressure reduction, it becomes a low-temperature, low-pressure refrigerant and enters the downstream refrigerator 24. The low-temperature, low-pressure refrigerant cools the water flow in refrigerator 24 and flows to gas-liquid separator 25. After gas-liquid separation, at least a portion of the refrigerant returns from the suction port to compressor 21 for the next cycle. Simultaneously, the heated water flow in water cooler 22 provides hot water to water-side valve island 1, and the cooled water flow in refrigerator 24 provides cold water to water-side valve island 1. Of course, as... Figure 9 As shown, in another embodiment, the function of the gas-liquid separator 25 can also be replaced by the liquid storage tank 30 downstream of the water cooler 22, which can be set as needed.

[0071] The cooler 22 in the agent-side integrated mechanism 2 is mainly used to directly supply high-temperature water to the water-side valve island 1, and the cooler 24 is mainly used to supply low-temperature water to the water-side valve island 1. The high-temperature water flows through the water-side valve island 1 through the corresponding functional element with heat exchange function, and is heated or used to dissipate heat from the water flow. Similarly, the low-temperature water flows through the water-side valve island 1 through the corresponding functional element with heat exchange function, and is cooled or used to heat the water flow. Under specific conditions, it is connected in series with the preset mechanism water circuit in the passenger cabin mechanism 3 and the fan heat exchange mechanism 4 to achieve the final thermal management function.

[0072] like Figure 1 As shown, by setting up the above system, the refrigerant side can be integrated (that is... Figure 1 The refrigerant-side integration mechanism 2 is located in the center of the system, resulting in a simple and highly safe pipeline organization. The entire refrigerant operation is integrated into the refrigerant-side integration mechanism 2, separate from other parts of the air conditioning system, and is not introduced into the passenger compartment. Figure 1 The passenger cabin mechanism 3 is located in a central position, which provides high safety. At the same time, the operation of the heat exchange water circuit is adjusted entirely through the water-side valve island 1. In the passenger cabin mechanism 3 and the fan heat exchange mechanism 4, heat control and distribution are achieved entirely by controlling the temperature of the water. This results in lower cost, easier pipeline organization, and higher safety.

[0073] In one embodiment, the electric heater 5 and the first water cooling passage of the water cooler 22 are connected in series to provide auxiliary heating for the water flow of the water cooler 22 when the heat source is insufficient. In this embodiment, the electric heater can be set to a power of 7 kW.

[0074] like Figure 1-8As shown, in this embodiment, the expansion valve 23 is an electronic expansion valve. Through the cooperation of the electronic expansion valve and multiple sets of sensors, high-precision monitoring of subcooling is achieved. This, combined with the gas-liquid separator 25, enables gas-liquid separation control, resulting in stable and highly accurate operation. In this embodiment, a first sensor 26 is connected in series between the compressor 21 and the gas-liquid separator 25. A second sensor 27 is connected in series between the compressor 25 and the water cooler 22. A water cooler temperature sensor 28 is connected in series between the water cooler 22 and the refrigerator 24. The first sensor 26 and the second sensor 27 are pressure and temperature sensors. In this embodiment, the expansion valve 23 is an electromagnetic expansion valve. The first sensor 26 upstream of the compressor 21 monitors the temperature and pressure of the refrigerant at the suction port to maintain equivalent operation. Similarly, for safety reasons, a second sensor 27 is also installed at the discharge port downstream of the compressor 21 for temperature and pressure monitoring, which is applicable to compressor structures without a pressure relief valve. The water cooler temperature sensor 28 upstream of the expansion valve 23 is mainly used for monitoring subcooling and coordinating with the electronic expansion valve to adjust the switch size. The gas-liquid separator 25 in this invention is mainly used to monitor subcooling. In conjunction with the corresponding sensors mentioned above, the monitoring results of subcooling are used to control the opening of the electronic expansion valve, so as to ensure the smooth flow of refrigerant.

[0075] like Figure 9 As shown, in another thermal management system with better cost control, the expansion valve 23 is configured as a thermostatic expansion valve. By placing the thermostatic expansion valve downstream of the water cooler 22, the refrigerant temperature can be controlled mechanically. Therefore, only a compressor temperature sensor 29 located downstream of the compressor 21 is needed to monitor superheat throughout the entire process, achieving stable refrigerant operation with fewer sensor components and lower cost. In this embodiment, pressure is controlled and superheat is detected using a thermostatic expansion valve. A liquid storage tank 30 located downstream of the water cooler 22 replaces the gas-liquid separator 25 for gas-liquid separation, reducing hardware costs while ensuring normal system operation.

[0076] Please see Figure 1 In one operating mode, the system cools the passenger cabin, maintains the temperature of the battery heat exchange unit 7, and dissipates heat from the drive motor heat exchange unit 8. Temperature control refers to keeping the temperature within a certain range, such as 20℃-30℃.

[0077] In this mode, the first water-cooling passage is connected in series with the outlet of the water cooler 22, the first valve port 11, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the eighth valve port 18, the drive motor heat exchange unit 8, the eighth valve port 18, the fourteenth valve port 114, and the inlet of the water cooler 22. The coolant flows sequentially through the outlet of the water cooler 22, the first valve port 11, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the eighth valve port 18, the drive motor heat exchange unit 8, the eighth valve port 18, the fourteenth valve port 114, and the inlet of the water cooler 22. In this embodiment, the high-temperature fluid that absorbs heat from the water cooler 22 and the drive motor heat exchange unit 8 sequentially is transported to the fan heat exchange unit 41 in the fan heat exchange mechanism 4 for external heat dissipation. During the heat dissipation process, the heat exchange fan 42 can be used to accelerate the heat dissipation speed.

[0078] The second water-cooling passage is connected in series with the outlet of the refrigerator 24, the thirteenth valve port 113, the second valve port 12, the cooler 31, the fifth valve port 15, the twelfth valve port 112, and the inlet of the refrigerator 24. Cooling fluid flows sequentially through the outlet of the refrigerator 24, the thirteenth valve port 113, the second valve port 12, the cooler 31, the fifth valve port 15, the twelfth valve port 112, and the inlet of the refrigerator 24. Similarly, in this embodiment, the low-temperature fluid cooled by the refrigerator 24 is transported to the cooler 31, and then blown by the blower 33 through the cooler 31 to cool the passenger cabin.

[0079] Simultaneously, the water path of the battery heat exchange unit 7 and the high-temperature fluid from the water cooler 22 and the low-temperature fluid from the refrigerator 24 are mixed in the water-side valve island 1. After flowing into the water-side valve island 1 through the tenth valve port 110, it flows back to the battery heat exchange unit 7 through the eleventh valve port 111. Therefore, the temperature of the battery heat exchange unit 7 can be controlled.

[0080] Please see Figure 2 In one of the operating modes, the system dehumidifies the passenger cabin, maintains and controls the temperature of the battery heat exchange unit 7, and dissipates heat from the drive motor heat exchange unit 8. Temperature control refers to keeping the temperature within a certain range, such as 20℃-30℃.

[0081] In this mode, the first water-cooling passage is connected in series with the outlet of the water cooler 22, the first valve port 11, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the eighth valve port 18, the drive motor heat exchange unit 8, the eighth valve port 18, the fourteenth valve port 114, and the inlet of the water cooler 22. The coolant flows sequentially through the outlet of the water cooler 22, the first valve port 11, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the eighth valve port 18, the drive motor heat exchange unit 8, the eighth valve port 18, the fourteenth valve port 114, and the inlet of the water cooler 22. The first water-cooling passage is also connected in series with the outlet of the water cooler 22, the first valve port 11, the third valve port 13, the heater 32, the fourth valve port 14, the fourteenth valve port 114, the eighth valve port 18, and the inlet of the water cooler 22. The coolant flows sequentially through the outlet of the water cooler and the heater 32 before returning to the inlet of the water cooler. In this embodiment, the high-temperature fluid that absorbs heat from the water cooler 22 and the drive motor heat exchange unit 8 sequentially is transported to the fan heat exchange unit 41 in the fan heat exchange mechanism 4 for external heat dissipation. During the heat dissipation process, the heat exchange fan 42 can be used to accelerate the heat dissipation speed. At the same time, in this embodiment, the high-temperature fluid heated by the water cooler 22 is also transported to the heater 32, and then the blower 33 blows it through the heater 32 to heat the passenger cabin.

[0082] The second water-cooling passage is connected in series with the outlet of the refrigerator 24, the thirteenth valve port 113, the second valve port 12, the cooler 31, the fifth valve port 15, the twelfth valve port 112, and the inlet of the refrigerator 24. Cooling fluid flows sequentially through the outlet of the refrigerator 24, the thirteenth valve port 113, the second valve port 12, the cooler 31, the fifth valve port 15, the twelfth valve port 112, and the inlet of the refrigerator 24. In this embodiment, the low-temperature fluid cooled by the refrigerator 24 is transported to the cooler 31, and then blown by the blower 33 through the cooler 31 to cool the passenger cabin.

[0083] Simultaneously, the water path of the battery heat exchange unit 7 and the high-temperature fluid from the water cooler 22 and the low-temperature fluid from the refrigerator 24 are mixed in the water-side valve island 1. After flowing into the water-side valve island 1 through the tenth valve port 110, it flows back to the battery heat exchange unit 7 through the eleventh valve port 111. Therefore, the temperature of the battery heat exchange unit 7 can be controlled.

[0084] Specifically, the cooler 31 and the electric heater 32 in the passenger cabin mechanism 3 can be operated intermittently, so that the cooler 31 plays a condensing role, and water in the air condenses in the cooler 31 and is discharged to achieve dehumidification. Then, the heater 32 is used to heat the air that is blown out by the blower 33, so as to maintain the stability of the passenger cabin temperature while ensuring dehumidification, so as to achieve the purpose of regulating humidity without excessive temperature regulation, and avoiding cooling the passenger cabin in environments where cooling is not required.

[0085] Please see Figure 3 In one of the operating modes, the system heats the passenger cabin, maintains and controls the temperature of the battery heat exchange unit 7, and dissipates heat from the drive motor heat exchange unit 8. Temperature control refers to keeping the temperature within a certain range, such as 20℃-30℃.

[0086] In this mode, the first water-cooling passage is connected in series with the outlet of the water cooler 22, the first valve port 11, the third valve port 13, the heater 32, the fourth valve port 14, the fourteenth valve port 114, and the inlet of the water cooler 22. The coolant flows through the outlet of the water cooler and the heater 32 in sequence and then returns to the inlet of the water cooler. It is then transported to the heater 32 by means of the high-temperature fluid heated by the water cooler 22, and then blown by the blower 33 through the heater 32 to heat the passenger cabin.

[0087] The second water-cooling passage is connected in series with the outlet of the cooler 24, the thirteenth valve port 113, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the ninth valve port 19, the drive motor heat exchange unit 8, the eighth valve port 18, and the inlet of the cooler 24. The coolant flows sequentially through the outlet of the cooler 24, the thirteenth valve port 113, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the ninth valve port 19, the drive motor heat exchange unit 8, the eighth valve port 18, and the inlet of the cooler 24. In this embodiment, the low-temperature water output from the cooler 24 absorbs heat in the drive motor heat exchange unit 8 and is then transported to the fan heat exchange unit 41 in the fan heat exchange mechanism 4 for external heat dissipation. During the heat dissipation process, the heat exchange fan 42 can be used to accelerate the heat dissipation speed.

[0088] Simultaneously, the water path of the battery heat exchange unit 7 and the high-temperature fluid from the water cooler 22 and the low-temperature fluid from the refrigerator 24 are mixed in the water-side valve island 1. After flowing into the water-side valve island 1 through the tenth valve port 110, it flows back to the battery heat exchange unit 7 through the eleventh valve port 111. Therefore, the temperature of the battery heat exchange unit 7 can be controlled.

[0089] Please see Figure 4 In one of the operating modes, the passenger cabin is ventilated, the battery heat exchange unit 7 is cooled, and the drive motor heat exchange unit 8 is cooled.

[0090] In this mode, the first water-cooling passage is connected in series with the outlet of the water cooler 22, the first valve port 11, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the eighth valve port 18, the drive motor heat exchange unit 8, the eighth valve port 18, the fourteenth valve port 114, and the inlet of the water cooler 22. The coolant flows sequentially through the outlet of the water cooler 22, the first valve port 11, the seventh valve port 17, the fan heat exchange unit 41, the sixth valve port 16, the eighth valve port 18, the drive motor heat exchange unit 8, the eighth valve port 18, the fourteenth valve port 114, and the inlet of the water cooler 22. In this embodiment, the high-temperature fluid that absorbs heat from the water cooler 22 and the drive motor heat exchange unit 8 sequentially is transported to the fan heat exchange unit 41 in the fan heat exchange mechanism 4 for external heat dissipation.
